    The invention relates to the drying of brown coal with a high moisture content and can be used in the chemical and other industrial sectors.
    The aim of the invention is to reduce energy costs.
    The drawing shows a plant for drying brown coal with high
    in content.
    The installation contains a bunker 1 for the original brown coal, a vibrating conveyor 2 in the form of a swinging trough, a vibrating screen 3 with pipeline A of the water gland, a vertically inclined belt conveyor 5, an intermediate bunker 6, - a lock chamber 7, a heater 8 with a drum screen 9 inside the drive 10, the psuch chamber 11, the autoclave 12 for treating coal with steam at a higher pressure with a rotating drum screen 13 with a screw inside the drive 14, a lock chamber 15, a desiccant 16 in the form of a vibrating dryer connected to the dedusting device 17 dp of dry coal, canopy — 1 ШВ collectors 18 for collecting waste water, pressure relief device 19 (steam generator and intermediate tank), heat exchanger 20 with heating cavity 21, 22 m separator of steam .
    Piston chambers 7,11,15 and screens 9 and 13 are equipped with drives with continuously variable rotation speed (not shown).
    The autoclave 12 is provided with pipelines 23 with discharge valves for discharging waste water to the mounted collectors 18 and pipes 24 for supplying saturated steam. Hinged collectors 18 are equipped with COj outlet nozzles 25 with sludge discharge nozzles 26 and a pipeline 27 for connecting to a steam generator, which in turn has a first steam line 28 for communicating with the heating cavity 21, heat exchange 1shka 20 dp heating the heat carrier supplied to the dryer 16, a second steam line 29 connecting the steam generator with a heater 8 having a line 30 for discharging waste water, connected to the separator inlet of 22 m of the steam to which the pipeline 3I is connected, is connected5

    with the output of the heating cavity 21 of the heat exchanger 20. A separator of 22 m of that pair is connected to the vibrating conveyor 2 by spraying coal via a pipe 32, and a couple to a vibrating screen 3 by tapping a pipe 33.
    Installation for drying brown coal works as follows
    The brown coal supplied from the bunker 1 gets onto the conveyor 2 made in the form of a swinging chute, where it is sprayed with hot water supplied through the pipeline 32. The coal is then heated to 40 - 60 Co. Then the heated coal is supplied to the vibrating screen 3. secondary steam and wastewater that heat the original coal.
    Vibrating screen's upper grating product 3 with a grain size of 3-40 mm falls on a vertically inclined conveyor belt 5 with a large lifting angle, through which it is fed through an intermediate hopper 6 and a rotating lock chamber 7 into the preheater 8. Inside it is a drum screen 9 seconds 10o drive To the heater 8 are connected lines 29 and 30 for steam supply and waste water, respectively. The preheater 8 is connected to the autoclave 12 through a rotating sluice chamber. Inside the autoclave 1 2 a rotating drum screen 13 with an actuator 14 is also placed.
    Pipes 24 and 23 are connected to autoclave 12 for supplying bulk steam and discharging waste water, respectively.
    The preheater is heated up to a maximum at a pressure of 15 bar and is preferably maintained at 120-150 Co. In autoclave 12, a drying process takes place, for which the coal is treated with saturated hot or superheated steam at a pressure of approximately 45 bar depending on the initial coal and residual its moisture content. The coal is discharged from the autoclave through the lock chamber 15, which is connected to the desiccant 16. In it, the coal is treated with a heated coolant, as a result of which the moisture evaporates further. The desiccant 16 is made in the form of a vibrating dryer connected to the dedusting device. The hot coolant is piped from the heat exchanger through the dryer through the dryer. Dried coal is discharged from the discharge conveyor 17
    It is most preferable to carry out drying in an autoclave with superheated steam. In this case, the steam is heated in such a way that upon subsequent evaporation of moisture contained in the coal, the vapor is saturated. In this way, saving of feed water and energy for steam generation is achieved, less condensate is formed, due to which the volume of wastewater to be treated is reduced. The problems associated with the use of superheated steam are simplified due to the previous preheating of the coal with steam under pressure, it remains only to take into account the moisture content of the coal after it is heated,
    The wastewater pipelines 23 are connected to the mounted collectors 18, in which the water removed from the coal and the condensate formed during the condensation of saturated steam are collected. Formed COj is discharged through nozzles 25, and solid components are discharged through nozzles 26 for sludge. The hot water through the pipeline 27 is sent to the pressure relief device 19 (steam generator), in which the pressure is reduced and as a result, steam is generated. The hot water is supplied to the heat exchanger 20 to preheat the heat transfer fluid entering the dryer. 22 m of that steam is directed to the separator through the pipeline. Secondary steam leaving the separator 22 is supplied to vibrating screen 3 through conduit 33, and hot water is directed to vibrating conveyor 2 through conduit 32. Excess water outflow through conduit 4 is diverted into the eyes tnye facilities.
    The steam generated in the pressure relief device 19, via line 29, is supplied to the preheater. The condensate withdrawn from the preheater via line 30 can be mixed with wastewater supplied through the pipeline from the heat exchanger cavity to separator 22 to separate the secondary steam.

    The saturated steam supplied to the autoclave 12 is expediently introduced by means of hydro-jet nozzles from above, onto the outer side of the casing of the drum screen. Thanks to this, it is also possible to prevent clogging of the holes in the casing of the drum disc It is preferable to use the drums of the slit construction. When using coal with a particle size of 3-40 mm, the degree of filling of the drum screen used as a dryer can be up to 60%. The capacity of the plant shown in the drawing can easily be increased to 60 tons / hour (for one drum screen). the coal in the autoclave 12 depends on the grain size of the coal, for coal with smaller particles it is smaller (for coal with a grain size of 5-20 mm, 5 minutes, with a size of 10-30 mm, 10 minutes and with a size of 20-40 mm, 20 min)
