:AND

The utility model relates to energy, in particular to devices for cleaning flue gases.

.Wet inertial ash collectors (C1fubbers) with an efficiency of about 85% are known. Ash collectors contain a hollow cylinder, lined with anticorrosive material inside. Its inner walls are washed inexorably by water, which flows down them from top to bottom. Flue gases are brought to the scrubber tangentially from below, due to which they receive a vortex movement, while the ash is pressed to the walls of the scrubber and washed down with water. The purified gases through the upper pipe are discharged to the exhaust fan. Their efficiency is significantly higher than that of dry mechanical ash collectors (about 85%). Up to 0.2 l of water is consumed for cleaning 1 m of gas. The disadvantage of limiting the widespread use of scrubbers

there is a need for industrial sewage and a significant consumption of water and the inability to utilize heat heated by flue gases of water (V.Kpanin. Boiler plants of small and medium power. Publishing House of Literature on Construction. M. 1968. p.252).

Known contact water economizers that use the heat of the exhaust gases to heat water during the combustion of natural gas. Such economizers include a housing with a water distributor located in it, gas ducts for supplying fyachy gas and for discharging cooled gas, a nozzle, a heated tank with a gas shutter and a device for its purging (I.Z. Aronov.

Use of heat of exhaust gases from gasified boiler houses. M.

Energy. 1967) - a prototype.

The disadvantage of contact water economizers is that they have a narrow scope - only for gasified boiler houses ..

The technical task of the claimed utility model is to expand the scope of contact economizers, in particular for solid and liquid

TOSH1IV ..

The technical problem is achieved by the fact that in the known device comprising a housing with a water distributor located therein, flues for supplying hot gas and cooling gas, nozzles, a heated water tank with a water seal and a purge device, a water heat exchanger and a screw feeder, a tank are installed in the heated water tank has the ability to decant ash particles, and also has the ability to heat

FROM hot flue gases.

Comparison of the claimed utility model with the prototype shows that it has the following features:

- a water heat exchanger and a screw feeder are installed in the heated water tank;

-tank has the ability to decant ash particles;

- The tank has the ability to heat from hot flue gases. Therefore, the claimed utility model meets the criterion of "novelty. The inventive utility model can be made on a standard

equipment using well-known techniques, poetry} it meets the criterion of "industrial applicability.

gases 5, nozzle 6, a water trap 7, a heated water tank 8 in which a heat exchanger 11 is located, a pipe for removing solid particles 9, a valve 10, a screw feeder 12, a gas jacket 13.

The device operates as follows.

Hot gases through the duct 4 are introduced under the layer of nozzle 6, irrigated with water. Cooled gases are discharged from the upper part through the duct 5, and hot water is collected in the heated water tank 8. The tank 8 is made in such a volume that solid particles are deposited (decanted) in its lower part. At the top of the tank there was a water trap 7, through which heated water Tociynac into the heating system. The precipitated solid particles together with part of the water are discharged into a special container and sent to the ash dump by screw feeder 12 through a pipe 9 and a valve 10. A heat exchanger 11 is installed in the tank 8, which allows receiving heated water not contaminated with aeol particles.

The inventive utility model allows to increase the efficiency by 10 - 12% due to the disposal of TenJiaj / flue gases, depending on the temperature of the flue gases.
