    one
    The invention relates to coal gasification, in particular to waste treatment devices of a coal gasification plant.
    The closest to the proposed technical essence and the achieved result is a device for waste treatment, including a downwardly narrowing tank, a slag-containing water supply pipeline connected to the central pipe, removal of slag in the bottom, flow of purified water in the upper part and separation wall l,.
    However, such a device design is coupled with the danger of clogging the channel for purified water with buoyancy slag.
    Object of the invention: nciBHui process reliability
    To this end, the waste treatment device, which includes a downwardly narrowing tank, a slag-containing water supply pipeline connected to the central pipe, a slag discharge in the bottom, an overflow, purified water in the upper part and a partition wall, is provided with an additional chamber located between the central pipe and the wall of the tank including two radial and horizontal partitions, the flow of purified water and the slag outlet, and the partition is vertically vertical to the central pipe with formation of two sections, the upper part of one of which is connected to the second camera.
    It is advisable to divide the partition equal to half the length of the pipe.
    In the second embodiment, the goal is achieved by the fact that in a waste treatment device, including a narrowing
    to the bottom of the tank, the pipeline supplying slag-containing water connected to the central pipe, the removal of slag in the bottom, the flow of purified water
    in the upper part and the dividing partition, the latter is located along the longitudinal axis of the tank with two sections, the upper edge of the partition is located above the flow of purified water, one of the sections is equipped with a 1ilak branch pipe located in the upper part below the upper edge of the separation partition, and the pipe
    d races; polzzzhena over the central part of the se (the station with a pipe outlet slag.
    FIG. 1 shows a first embodiment of a waste treatment device, a slit; in fig. 2 - the same, top view; in fig. 3 is the same as the second embodiment; in fig. 4 - the same, top view,
    The proposed device (FIG. 2) contains a reservoir 1 located vertically with a narrow end.
    - down, pipe 2, additional chamber 3 formed by radial partitions 4 and horizontal partition 5, pipeline b of slag-containing water supply, outlet 7
    0 slag, the flow of 8 purified water, the partition wall 9, the tray 10 discharge of purified water. The partition wall 9 divides the interior of the pipe into two
    5 sections L1 and 12 and ends in the middle of pipe 2, i.e. half way through pipe 2. The device also contains drain pipes 13 and 14 for purified water
    The device works as follows.
    in a way.
    Slag-containing water flows through pipe b into pipe 2. Slag particles leaving the inlet .-
    piping 6 and entering in connection with the pump pressure forcibly down into the pipe 2, have a different specific gravity. Particles with buoyancy due to a lower specific weight compared to water are constantly affected by lift force, which is overcome in the supply pipe 6 by pump pressure. At the end of the dividing partition 9, the slag particles are able to break out of the feed stream and rise again into the pipe section 12, then the slag particles having buoyancy flow from the pipe section 12 into the chamber-3, and at the tray 10 with a rather weak flow of water are retained or accumulate.
    Slag particles with a specific gravity higher than water flow out of pipe 2 downward and continue their trajectory of movement in the direction of the lower end 1, at the lower end of which they are collected. Particles can be withdrawn from there continuously or at regular intervals. Purified water through tray 10 and overflow 8 enters the different discharge lines 13 and 14.
    Separating slag particles with buoyancy using tray 10 and chamber 3 requires repeated periodic cleaning or emptying of chamber 3. Otherwise, if chamber 3 is not fully filled with water along with drain pipe 13, slag particles simultaneously enter through drain tray . The drain pipes 13 and 14 can also be interconnected and connected to the drum screen.
    According to the second embodiment (Figs. 3 and 4), the device comprises a tank 1, a pipe 2, a dividing wall 3, which divides the tank 1 into two sections 4 and 5, a slag-containing pipeline 6, discharging slag 7 in the bottom, and overflow 8 of purified water nipple 9
    removal of slag, pipe 10 removal of purified water.
    The device according to the second variant operates as follows. .
    The slag containing water leaving the feed pipe b is throttled through pipe 2 and is fed to the water surface of section 5, to particles that have buoyancy, due to the low specific weight compared to water.
    there is a hydrostatic lifting force which contributes to the fact that these particles remain on the surface. The overflow of these particles into the overflow 8 5 is prevented by the clarified water mirrors located above and the edge of the partition 3 ..
    Slag particles with a higher specific wave compared with water come out of pipe 2 and continue to move towards the lower end of tank 1, where they are collected and from where they can be withdrawn continuously or at certain time intervals.
    The clarified water is discharged through the overflow 8 and the nozzle 10. At the nozzle 9, the slag particles with buoyancy can be unloaded continuously or at certain intervals of time. In addition, optionally, a mechanical grid is installed in section 5, which additionally removes slag particles having a buoyancy.
    The proposed device removes most of the slag particles from the water, so that the water can be safely sent to the existing
    0 a system for wastewater, either by recirculation, is again fed to the water bath in the gasification reactor or to the series-connected waste heat boiler.
    5, the slag is temporarily collected in its pure form, i.e. not mixed with other waste products and products, which opens up various possibilities for its further use.
