=11°÷24° к горизонтальной касательной линии 14 наружной поверхности корпуса и непосредственно соединенной с цилиндрической частью 15 корпуса, капельно-пылегазовая смесь плавно и поэтому с низким гидравлическим сопротивлением входит в цилиндрическую часть 15 и идет далее вниз по усеченному конусу нижней части 16 корпуса в виде пристеночного нисходящего капельно-пылегазового вихря. Во входном патрубке 1 для газа, цилиндрическом патрубке 9 и переходнике 10 происходят тепломассообменные процессы, а в тангенциальной улитке 12, цилиндрической 15 и нижней части 16 корпуса, кроме тепломассообменных процессов дополнительно осуществляется центробежная сепарация капельно-пылегазовой смеси, вследствие которых происходит абсорбция вредных газов каплями жидкости, осаждение частиц пыли на каплях жидкости, прижатие капель жидкости с уловленными газами и частицами пыли к внутренней поверхности улитки 12, цилиндрической 15 и нижней частей 16 корпуса. В результате газы очищаются от пыли и вредных газовых компонентов, а капли жидкости с уловленными пылью и вредными газами образуют на внутренней поверхности улитки 12, цилиндрической 15 и нижней частей 16 корпуса вращающуюся нисходящую пленку, которая в виде шлама стекает через шламовыпускное отверстие 17 нижней части 16 корпуса в сборник 18 шлама, и через его патрубок 19 шлам удаляется. Грубо очищенные газы с остаточным содержанием вредных газовых компонентов, частиц пыли и капель жидкости в нижней части 16 корпуса разворачиваются на 180° и в виде внутреннего восходящего газового вихря плавно удаляются из корпуса в спиральную улитку 26 через выходной цилиндрический патрубок 20 для газа, диффузор 24 с углом γ=30°÷45° и его выходное отверстие 25, через отверстие 27 в центре нижней стороны 28 спиральной улитки 26. Очищенные газы удаляются из спиральной улитки в выходной газоход 50 очищенного газа через выход 30 спиральной улитки 26. В спиральной улитке 26 происходит дополнительная центробежная сепарация капельно-пылегазового вихря и его раскручивание в прямопоступательный газовый поток на выходе 30 из спиральной улитки 26, благодаря чему происходит дополнительная очистка газов от вредных газовых компонентов, частиц пыли и капель жидкости и одновременно снижение гидравлического сопротивления устройства. Капли жидкости образуют на внутренней поверхности боковой стороны 29 спиральной улитки 26 вращающуюся пленку жидкости, которая удаляется в виде шлама из спиральной улитки 26 через отверстие 31 прямоугольной формы на боковой стороне 29 спиральной улитки 26 у ее выхода 30, и по направляющей пластине 33 пленка жидкости попадает в цилиндрический желоб 38, через отверстие 37 прямоугольной формы в нем. В цилиндрическом желобе 38 пленка жидкости закручивается и тем самым не происходит выброса капельно-пленочной жидкости обратно в спиральную улитку 26. Попадание пленки жидкости в цилиндрический желоб 38 и закручивание пленки жидкости в нем происходит благодаря прикреплению направляющей пластины 33 под углом θ=155°÷165° к поверхности боковой стороны 29 спиральной улитки 26, сопряженному соединению направляющей пластины 33 с отверстием 37 прямоугольной формы цилиндрического желоба, креплению внешней поверхностью цилиндрического желоба 38 к вертикальному краю 40 отверстия 31 прямоугольной формы улитки 26, ближнему от выхода 30 спиральной улитки 26, сверху, а также тому, что снизу направляющая пластина 33 и цилиндрический желоб 38 закрыты крышкой 41 и днищем 42. Вращающая и нисходящая пленка жидкости из цилиндрического желоба 38 удаляется в сборник 18 шлама через нижний торец 43 цилиндрического желоба 38, соосно прикрепленные конфузор 44 с углом φ=30°÷45°, корпус 45 задвижки 46, трубопровод 47 и соединение с крышкой 48 сборника 18 шлама. Вместе с пленкой жидкости возможно эжекционное удаление в сборник 18 шлама капельного аэрозоля благодаря тому, что трубопровод 47 цилиндрического желоба 38 соединен с крышкой 48 сборника 18 шлама под углом ψ=30°÷45° к ее плоскости по ходу вращения газов внутри сборника 18 шлама. Расход капельного аэрозоля регулируется посредством задвижки 46.From the inlet duct 49, crude gas is supplied to the inlet 1 for gas. At the same time, liquid is sprayed perpendicularly to the gas stream in the gas inlet 1 through three sprinklers of the liquid spraying device: the liquid is supplied to the inlet pipes 5 of the annular pipe 4, the intermediate pipes 6 with pairs of nozzles 7 installed in the holes 3 of the gas inlet 1. Outgoing two jets of liquid from each pair of nozzles 7 as a result of their collision are sprayed in the inlet pipe 1 for gas in the form of a finely dispersed droplet stream transverse to the dust and gas stream in it. The droplet-dust-gas mixture formed inside the inlet pipe 1 for gas from the gas inlet pipe 1 made in the form of a confuser with an angle β = l5 ° ÷ 25 ° smoothly enters the cylindrical pipe 9, in which the interaction of liquid droplets is effective in turbulent speed mode with dust and gas and then smoothly through the adapter 10 is fed into the input 11 of the cochlea 12 of the housing with minimal hydraulic resistance. In the cochlea 12, the axis 13 of which has an angle of inclination

= 11 ° ÷ 24 ° to the horizontal tangent line 14 of the outer surface of the casing and directly connected to the cylindrical part 15 of the casing, the dust / gas mixture smoothly and therefore with low hydraulic resistance enters the cylindrical part 15 and goes further down the truncated cone of the lower part 16 of the casing in the form of a parietal descending droplet-dust-gas vortex. Heat and mass transfer processes occur in the gas inlet 1, cylindrical pipe 9 and adapter 10, and in addition to the heat and mass processes, centrifugal separation of the dust / gas mixture is carried out in addition to the heat and mass transfer processes in the tangential scroll 12, cylindrical 15 and lower part 16 of the housing, due to which harmful gases are absorbed by drops liquids, the deposition of dust particles on liquid droplets, the pressing of liquid droplets with trapped gases and dust particles to the inner surface of the cochlea 12, cylindrical 15 and lower astey 16 housing. As a result, the gases are cleaned of dust and harmful gas components, and liquid droplets with trapped dust and harmful gases form a rotating downward film on the inner surface of the cochlea 12, cylindrical 15 and lower parts 16 of the body, which flows in the form of sludge through the sludge outlet 17 of the lower part 16 housing in the collector 18 of the sludge, and through its pipe 19, the sludge is removed. Coarse cleaned gases with a residual content of harmful gas components, dust particles and liquid droplets in the lower part of the housing 16 are rotated 180 ° and smoothly removed from the housing into the spiral scroll 26 through the cylindrical outlet pipe 20 for gas, diffuser 24 s angle γ = 30 ° ÷ 45 ° and its outlet 25, through the hole 27 in the center of the lower side 28 of the spiral scroll 26. The purified gases are removed from the spiral scroll into the outlet gas duct 50 of the purified gas through the outlet 30 of the spiral scroll 26. cial cochlea 26 occurs more centrifugal separation of dust and gas-drip vortex and its unwinding in pryamopostupatelny gas stream at the outlet 30 of the spiral of the cochlea 26, whereby there is additional cleaning gas from harmful gas components, dust particles and liquid droplets and simultaneously decrease the hydraulic resistance of the device. Drops of liquid form a rotating liquid film on the inner surface of the side 29 of the spiral snail 26, which is removed as sludge from the spiral snail 26 through a rectangular opening 31 on the side 29 of the spiral snail 26 at its outlet 30, and the liquid film enters along the guide plate 33 into a cylindrical trough 38, through a hole 37 of a rectangular shape in it. In the cylindrical groove 38, the liquid film is twisted and thus the droplet-film liquid is not ejected back into the spiral cochlea 26. The liquid film enters the cylindrical groove 38 and the liquid film twists in it due to the attachment of the guide plate 33 at an angle θ = 155 ° ÷ 165 ° to the surface of the side 29 of the spiral scroll 26, the conjugate connection of the guide plate 33 with the hole 37 of the rectangular shape of the cylindrical trough, fixing the outer surface of the cylindrical trough 38 to the vertical the steel edge 40 of the hole 31 of the rectangular shape of the scroll 26, closest to the exit 30 of the spiral scroll 26, from above, and also the fact that the bottom of the guide plate 33 and the cylindrical groove 38 are closed by the cover 41 and the bottom 42. The rotating and descending liquid film from the cylindrical groove 38 is removed into the sludge collector 18 through the bottom end 43 of the cylindrical trough 38, the confuser 44 coaxially attached with an angle φ = 30 ° ÷ 45 °, the valve body 45, pipe 47 and the connection to the cover 48 of the sludge collector 18. Together with the liquid film, ejection droplet aerosol can be removed into the collector 18 due to the fact that the pipe 47 of the cylindrical trough 38 is connected to the cover 48 of the slurry collector 18 at an angle ψ = 30 ° ÷ 45 ° to its plane along the rotation of the gases inside the slurry collector 18. The flow rate of the drip aerosol is regulated by means of a valve 46.

The technical result of using the device for wet gas purification is to reduce the hydraulic resistance of the device by 2.5 ÷ 5.0 kPa while increasing productivity to 500 ÷ 1000 thousand m ³ / h and gas cleaning efficiency to 99.0 ÷ 99.5% him.
