    FIELD OF THE INVENTION
    The present invention relates to the field of a solid waste incineration processing technology, in particular, it relates to a municipal solid waste incinerator or specifically to a municipal household waste incinerator. BACKGROUND OF THE INVENTION
    Existing waste processing technologies mainly include incineration, landfill, composting, waste recycling, etc. In these common waste processing technologies, the incineration process has the advantages of reducing the bulk of the waste notably, being completely without prejudice, occupying a small land area, using waste heat and minimizing secondary pollution, etc., which is in accordance with our country's sustainable development strategy.
    In existing incineration processes and devices, there are various forms of grid-type incinerators, the application of which occupies more than 80% of the total amount of the waste incineration market around the world. In one type of incinerator, all grates in the incinerator body are reverse pusher type grates, or specifically, reverse thrust grates, via tilt and reverse, or specifically a reverse thrust, the bottom layer residue of material layers move up and the top material layer residue layer moves down, the residue is turned over and stirred continuously into full contact with the air, and thus the residue is completely burned. By the way, due to the fact that the reverse pushing action of the reverse pusher type grids can correspondingly prolong the residence time of the waste within the incinerator, under the same treatment capacities, the reverse pusher type grid has an area smaller than the grid of the pusher type. The existing problems of this type of incinerator are listed as follows: firstly, for solid waste, or specifically domestic waste in our country having the characteristics of high water content and complex ingredients, etc., a transportability of the reverse pusher type grid to the waste is relatively poor, in particular the bottom layer waste from the material layers in the drying stage is very likely to coagulate into batters or cakes and adhere to the surfaces of the grids, and It thus stops the movement or moves very slowly, and only when the water content in the drying stage gradually decreases, the residue is transported further. Second, in the drying stage, the bottom layer residue can adhere to the surfaces of the grids locally and thereby block the primary air holes in the grids and affect the air supply, in particular on drying, and prolong the drying time, delay ignition for residue combustion, increase residue residence time inside the incinerator in the whole process, which will directly affect the incineration process inside the incinerator. Thirdly, due to the fact that a material pusher continuously feeds material to the incinerator, in the drying stage, the upper layer waste is extruded to be transported forward, while the bottom layer waste is transported in such a way. relatively slow, therefore, the movement speed of the top layer residue and the bottom layer residue are obviously different.
    Additionally, in another type of incinerator, all the grates in the incinerator body are pusher-type grates or, specifically, thrust-forward gratings, by means of tilt and thrust, or specifically thrust forward, the layers of material entire residues move downwards, the grates and layers of material move in the same direction, and through height differences between front grates and rear grates or grate courses, the residue is loosened and turned over, and the residue becomes moving forward fully in contact with the air, and thus the residue is completely burned off. The existing problems of this type of incinerator are listed as follows: firstly, in order to guarantee the residence time of the waste within the incinerator, the grate areas are flagged to be larger or the grate courses are designed to be more long, thus the height or length of the incinerator is increased and the cost is increased. Second, the gratings and the layers of waste material move in the same direction, when the layers of waste material are higher, the relative height difference between adjacent gratings is lower and the relative travel is shorter, the moving residue is almost presented in a relatively steady state, thus a bad effect on stirring and mixing is obtained, and the residue is not fully dry and cannot be completely burned, resulting in inefficient combustion and efficiency. of low combustion, which is difficult to meet the requirement of a clinker ignition loss. Thirdly, by the way, before being evaporated, the leachate in the residue layers is pushed to flow forward through the grids, thus the drying time of the residue is increased, all the leachate, which is not accumulated along the time, it is evaporated to be changed to steam inside the incinerator, which increases the water content in the smoke, thereby affecting the incinerator process. The residue is delayed from ignition to combustion, thus the residence time of the residue within the incinerator in the entire process is increased and greatly affects the incineration process. Fourthly, the incineration process controls the movement of the grates in a periodic control mode, that is, the grates move at a certain time and then stop, after breaking, the grates continue to move. For solid waste in our country having the characteristics of high water content and complex ingredients, etc., the time change in stopping and moving is greater, and the process parameters are regulated at a relatively high frequency. Therefore, the incineration process parameters need to be regulated when the incinerator is used in different regions and the control method also needs to be adjusted accordingly. Fifthly, the grids stop for a part of the time in the periodic control mode, if the time is too long then the grids are likely to be burned in the lower position of the material layer, whereas the upper position of the layer of material is not fully dry and it is difficult to be incinerated completely, if the time is too short then it cannot ensure the residence time inside the incinerator, which will result in a low combustion efficiency, in both cases being difficult to meet the clinker ignition loss requirement. Sixth, if the waste incinerator is divided into too many sections, then the complexity of the mechanism will be increased, thus the failure rate and cost being higher, and a higher requirement for the system algorithm is created. control.
    Furthermore, there is a grate-type incinerator with two-section type grates within the incinerator, wherein a front section adjacent to a hopper includes downwardly sloping reverse pusher-type grates, and a rear section adjacent to a hopper. slag includes pusher type grates. Inclined reverse pusher type grids work in the drying and combustion stage, horizontal pusher type grids work in the burning stage, there is a height difference between the two sections, thus a release of residue and a turning of the layers of waste material are carried out, the waste transported forward fully contacts the air, thereby the waste being completely incinerated. The existing problems of this type of grid type incinerator are listed as follows: firstly, for solid waste in our country having the characteristics of high water content and complex ingredients, etc., the transport capacity of the Reverse pusher type grids for the waste is weaker, particularly in the waste drying process, there are the same problems as in the entire reverse pusher type grids. Second, in the burning stage with pusher type grates, the waste is basically incinerated into clinker, most of this clinker having a very small size, and with the development of the burning stage the clinker content increases until it reaches the cinker ignition loss requirement, i.e. the movement of horizontal pusher type grates transports very small size clinker, which has a very high probability of entering an underlying primary air chamber through spaces between grates or primary air orifices, thus the air chamber discharging a large amount of clinker, which is unfavorable for the unified collection and treatment of clinker. Thirdly, clinker or ash may enter a moving mechanism part inside the primary air chamber, which will cause severe abrasion wear on kinematic parts thereby affecting normal operation of the mechanism, and clinker may accumulate on a fixed plate or a fixed beam, thereby affecting the function of the primary air passing through the layers of material and entering the incinerator to aid combustion and burning of the waste.
    To summarize, typical alternative grid type waste incinerators have their respective advantages, but they need to solve the following problems and drawbacks in a real application in our country:1. For solid waste in our country having the characteristics of high water content and complex ingredients, etc., the transport capacity of the reverse pusher type grids for the waste is relatively weak, particularly in the drying stage, the layer of waste material has a high probability of coagulating into batters or cakes and adhering to grid surfaces, thereby affecting the drying process and waste transport;2. In reverse pusher type grids, in the drying stage, the bottom layer residue can adhere to the grid surfaces locally and thereby block the primary air holes in the grids, prolonging the drying time, increasing the drying time. Residue residence within the incinerator in the entire process, which will directly affect the incineration process within the incinerator;3. Because the material pusher continuously feeds the material to the incinerator, in the drying stage, the top layer residue is extruded to be transported forward, while the bottom layer residue is transported relatively slowly, therefore, the movement speed of the top layer residue and that of the bottom layer residue are obviously different;4. In order to guarantee the residence time of the waste within the incinerator, the grate areas are signaled to be larger or the grate courses are designed to be longer, thus the height or length of the incinerator is increased and the cost is increased;5. Pusher type grids and layers of waste material move in the same direction, when layers of waste material are higher, the relative height difference between adjacent grids is lower or the relative travel is more short, the moving residue is almost presented in a relatively stationary state of being, thus a bad effect on stirring and mixing is obtained, the residue is not fully dry and cannot be fully burned, resulting in inefficient combustion and a low combustion efficiency, which is difficult to adapt to the clinker ignition loss requirement;6. Before being evaporated, the leachate in the residue layers is pushed to flow forward through the pusher type grids, thereby the drying time of the residue is increased, all the leachate, which is not accumulated over time, is evaporated to be changed into steam within the incinerator, which increases the water content in the smoke, thereby affecting the incineration process;7. For pusher type grates, the incineration process controls the movement of the grates in a periodic control mode. For solid waste in our country having the characteristics of high water content and complex ingredients, etc., the time change in stopping and moving is greater and the process parameters are regulated at a high relative frequency, so that the incineration process parameters need to be regulated when the incinerator is used in different regions and the control method also needs to be adjusted accordingly;8. The grates stop for a part of the time in the periodic control mode, if the time is too long then the grates will have probabilities of being burned in the lower position of the material layer, whereas the upper position of the material layer it is not fully dry and it is difficult to be incinerated completely, if the time is too short then it cannot ensure the residence time inside the incinerator, which will result in a low combustion efficiency, in both cases, being difficult to adapt to the clinker ignition loss requirement;9. If the waste incinerator is divided into too many sections, then the complexity of the mechanism will be increased, thus the failure rate and cost are higher, and a higher requirement for the control system algorithm is created;10 . In the burning stage with pusher type grates, the waste is basically incinerated into clinker, most of it being clinker with a very small size, and with the development of the burning stage, the clinker content increases until it reaches the requirement. loss of clinker ignition, i.e. the movement of horizontal pusher type grates transports very small sized clinker, which has a high probability of entering an underlying primary air chamber through spaces between the grates or air holes primary, thus the air chamber discharging a large amount of clinker, which is unfavorable for the unified collection and treatment of the clinker.
    Furthermore, clinker or ash may enter a moving mechanism part within the primary air chamber, which will cause severe abrasion wear on the kinematic parts, thereby affecting the normal operation of the mechanism, and clinker may accumulate on a fixed plate or a fixed beam, thereby affecting the function of the primary air to pass through the layers of material and enter the incinerator to aid combustion and burning of the waste.

    One end of the material push platform is occupied with the leading end of the drying section grid with a large height difference to ensure that the residue can fall onto the pusher drying section grid to be completely plugged. For the drying section grid, in order to ensure the residue transporting effect and prevent ineffective grid residue transport or accumulation in a dough or cake, when the residue is dried and burned, the entire grid is a grid of pusher type, the heads of the grate pieces face a low end of the entire grate. For the 10 burning and burning section grate, the entire grate is a reverse pusher type grate, the heads of grate pieces face towards a high end of the entire grate, which is useful for the boost control effect of the residence time of the residue within the incinerator and thoroughly mixing and agitating the residue, thereby ensuring the reliability of residue transport and the technical effect of incineration of the combustion and burning section. The left and right levers of the pusher type section and the reverse pusher type section are connected to the movable beams for the formation of lever frames, which have high structural strength and can guarantee movement synchronization every 20 grate grid plate in the same section. The lever is supported by the support roller device, which can reduce the resistance to the lever movement, improve the operation reliability and stability of the grate system, and increase the service life.

    A pre-drying air chamber is provided under the material pushing platform and an accumulation window is provided at a lower end of the pre-drying air chamber, an upper end of the pre-drying air chamber has a shaped like a horn, which is larger at the top and smaller at the bottom, and a hot air supply window is provided in the side wall of the horn. the pre-drying air chamber through the hot air supply window and is blown to the material thrust platform, treats the residue on the material thrust platform through a primary preheat and drying, the residue after the Pre-heating and drying treatment is fed to the two-section type grid inside the incinerator, thus it can shorten the drying time in the drying section, reduce the water content in the residue and increase the heat value of incinerator. tion of the waste. A lower end of the pre-drying air chamber has a leachate accumulation function leaking from the material pushing platform, which is favorable for comprehensive leachate treatment.

    The primary air holes provided in the heads of two adjacent grate pieces in the width direction are also alternated transversely, forward and backward. As a result, it has a function of obviously disturbing, cutting and mixing the longitudinal and transverse residue and increasing the instability of the residue in the grate, at the same time being favorable to the fixed connection between the grate pieces in the same row. The front ends of the grates are aligned with each other and each piece of grate is subjected to a uniform force, and each row of movable grate plates can operate smoothly and permanently.

    The drive mechanism of the pusher type section is arranged at the leading end, ie, under the material pusher device of the incinerator, there is little equipment. For waste with a higher water content, there is more leachate, which is likely to corrode device components. In this case, the front swingarm drive mechanism or the front direct drive mechanism can be used to better solve the leachate problem and reduce corrosion of device components. For the residue with a lower water content, there is some leachate, which is less likely to corrode device components.
