    An apparatus and arrangement is disclosed for cooling glowing coke in a dry circuit which utilizes a cooling chamber divided by cooling walls into a plurality of parallel vertically extending cooling channels. The cooling walls are supplied with a cooling medium for indirectly cooling the glowing coke. A coke discharge mechanism in the form of a chute having a comb-like end and paddle wheels between the teeth of the comb is provided at the bottom of each cooling channel to discharge coke from the cooling chamber in a controlled fashion to an underlying after-chamber. Each cooling channel is provided with cooling gas for directly cooling the glowing coke. An arrangement utilizing the apparatus supplies cooling gas directly to the cooling channels which, after passing out of the cooling chamber, passes into a waste heat boiler which is supplied with water so that it is heated by the now hot cooling gas to produce steam. Cooling water is also provided to the cooling walls for producing additional steam and for being heated in the waste heat boiler.

    专利说明:

    The invention relates to dry quenching of coke, in particular to a coke quenching device.
    A device for dry quenching of coke is known, comprising a prechamber with a charging opening for introducing hot coke, a cooling chamber below it, equipped with means for supplying cooling gas and coke removal located at its lower end, and means for withdrawing gas located between the prechamber and a cooling chamber, the prechamber and the cooling chamber are made of fire-resistant material, and the device for supplying the cooled gas contains a tower stand, located in the lower part along the vertical cooling chamber axis 1.
    A disadvantage of the known device is that in order to ensure the required quality of quenching, quantities of cooling gases must circulate, which requires not only an adequate consumption of electrical energy for the fan, but also the use of a corresponding device for dedusting the cooled gas. In addition, due to the refractory lining, before putting the device into operation, as well as before putting the device into operation after repair work, it must be heated for several days.
    The purpose of the invention is to reduce energy consumption.
    This goal is achieved by the fact that, in the proposed coke dry quenching device containing a prechamber with a charging opening for introducing hot coke, there is a cooling chamber below it, equipped with means for supplying cooling gas and removing coke located at its lower end, and means for exhausting gas, located between the prechamber and the cooling chamber, the cooling chamber is provided with vertical parallel internal cooling walls connected to means for circulating refrigerant and steam laid spaced 0.060, 15 of their height to form a cooling zone, i.ustroystvo has several tools for removing coke arranged underneath each cooling zone.
    The cooling gas supply means has channels with a surface sloped in the direction of the coke exit, located above the coke removal means; internal cooling walls made of pipes.
    Cooling KciMepa is made with a square or rectangular cross section.
    FIG. 1 shows the device; vertical section in FIG. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - part of cooling zones with a discharge device, horizontal section; Fig. 5 shows a device with two feed openings, a vertical section; FIG. 6 is a section BB in FIG. .five,
    A device for cooling coke consists of a pre-chamber 2 with refractory lining 1, having feed ports 3 for hot coke, parallel and horizontal channels 4 for removing heated inert circulating gas and a common channel 5 for gas exhaust b.
    Below the prechamber is a vertical cooling chamber 7 with a quadrant or rectangular cross section, the outer walls 8 of which are made with water cooling in the upper part. In order to avoid deformation, the walls are provided with an external support 9. The vertical cooling chamber 7 is provided with vertical - parallel water-cooled flat walls 10, which are located at a distance with the formation of cooling zones 11,. sootvetsnuitsem 0,06-0,15 of their height. The walls 10 have distribution pipes 12 and collector pipes 13. 1 distribution pipes 12 are installed on steel bearing walls 14 perpendicular to the pipes 12. To the top, the bearing walls transform into screens 15 of refractory material and serve to direct coke and gas, as well as Stabilization of the walls 8 and 10. On the screens 15 there are supports 16 for the pre-chamber. Along the lower portion of the supporting walls 14, a cooling gas supply channel 17 is provided, which is made with a triangular cross section. At the lower end of the cooling zones 11, cooling gas is fed through the holes 18 in the channels .. 17 into the scarlet coke located in the cooling zones 11. The skew surface 19 of the channel 17 senses the pressure of the vertical layer and allows the coke to be efficiently discharged at the discharge chute 20 in which the direction of the coke pattern changes, and at its end, made in the form of a comb 21, the flow stops.
    Between the teeth of the comb 21, the teeth of the swiveling unloading plug 22 pass, and each time a constant amount of coke is unloaded from the front end of the chute 20 into the chamber 23. All unloading forks under the cooling gas supply channel are located on a common shaft 24 "All shafts are directed outwards and have a common drive (not shown), which is made with the possibility of infinitely variable control, as a result of which the rate of fall of coke in all cooling zones 11 is the same and can be easily adjusted to the flow rate of coke. The chamber 23 has inclined side surfaces along which the coke moves to the lowest point, where the scraper conveyor 25 is capable of moving. infinitely adjustable, discharging coke. A protective cover 26 prevents overloading of the scraper conveyor 25. The diverter 27 doses coke to the scraper conveyor. . The device works in the following way. The coke enters the prechamber 2 through the charging opening 3. The cooling gas is directed through the distribution pipe 28 and the pipe 29 to the channels 17 for supplying the cooling gas. An adjusting valve 30 is located in each pipe 29 for setting the gas quantity, so that the cooling gas is evenly distributed over the entire cross section of the cooling chamber 7. Coke is additionally cooled by the refrigerant supplied to the water-cooled flat walls 10. The energy savings achieved by the invention are considerable. So, for example, with a coke consumption of 60 t / h, a coke temperature of 1000 ° C and a cooled coke temperature of 200 ° C, saving electrical energy to operate the cooling gas circulation fan is 80%, since under such conditions only 60,000 HMV of cooling is needed gas compared to 95,000 nm / h according to the prototype. With an amount of 60,000 circulating gas, and due to the low resistance due to the formation of cooling zones 11, the fan consumes only 1.44 kWh / t of coke, while at 95,000 HMV4 the fan consumes 7.2 kWh / t of coke. When the distance between the water-cooled walls is less than 0.06 in height, for example, 0.04 in height, high-pressure steam production, which is an additional advantage of the proposed solution over the known one, is reduced by 60-70%. When the condition is greater than 0.15, for example, 0.2 heights, the amount of circulating gas should increase by 35-40%, otherwise the required condition of the extinguishing mode is not provided; but increasing the amount of gas leads to an undesirable increase in power consumption. Reducing the time for heating the device before its operation is an additional advantage of the proposed device over the known one. So, for example, in the case of a known device, the heating carried out by supplying hot air lasts about 2-3 days, and in the case of the proposed device, it does not take longer than 24 hours. Cokpa It-time for heating is due to the fact that only the prechamber was made with refractory lining (cooling chamber is made of metal), while the known solution provides for the implementation of a refractory lining of the entire device (without heating, the device's service life is insufficient). The advantage of the proposed device is that due to the formation of cooling zones, not only the cooling capacity is increased, but the heat can also be utilized for direct steam production.
