Description

t

This invention relates to devices.

SWH wet gas cleaning, to dedust and neutralize exhaust gases of drying plants in the production of potassium chloride.

A shock scrubber de-5 gas scrubber is known - a Doyle scrubber consisting of a hull, an inlet pipe into which a Cone is inserted, and ° vertical partitions l.

A disadvantage of this device is the lack of devices for separating liquid droplets from outgoing gaas.

The closest to the proposed technical essence and the achieved result is a scrubber that includes a housing, a hopper for collecting irrigating liquid, a device for introducing contaminated gas, nozzles for extracting the purified gas and the waste liquid 2.

The drawback of the device is a high level of fishery with an increased consumption of energy from the flue gases.

The purpose of the invention is to reduce the hydraulic resistance, increase the cleaning efficiency and reduce the bryagunos.

The goal is achieved by the fact that the device for introducing contaminated gas is equipped with a cap with vertical gaps, pockets placed in the gaps and having outlet pipes, the axes of which are directed at a solid angle to the inner surface of the housing, while the bottom wall of the pocket is located above the bottom edge the cap and is made with a hole in the cavity of the cap.

In addition, the cap is made rectangular in shape, and the upper walls of the cap and pockets are inclined.

Claims (2)

FIG. 1 shows a scrubber, with a view, FIG. 2 shows a section A-A in FIG. 1. It consists of a vertically mounted cylindrical body 1 having a bottom and a lid. In the lower part of the housing there is a device 2 for introducing a contaminated gas, equipped with a nozzle 3 for 78 to start and spray water, as well as a nozzle 4 for discharging waste liquid, connected to overflow 5 to maintain a predetermined level of water in the scrubber. Inside the housing, a nozzle 6 is installed along its axis to discharge the purified gas. It is passed through the lid and bottom and communicates with the atmosphere with its open ends. On the pipe 6 in that part, which is located under the cover of the housing, there are windows 7 for the gas to enter the pipe. A device 2 for introducing contaminated gas is provided with a rectangular bell 8 which is hermetically coupled to the pipe 9. In the inclined upper wall and the lower end wall adjacent to it there are two slots 10 (their number can be changed) into which the pockets 1.1 are inserted also rectangular with an inclined upper wall and outlet nozzles 12. The peculiarity of the pocket is that in the part that is located inside the cap, the bottom wall is made with a window 13, the bottom wall of the pocket is located above the lower edge of the cap. In addition, the axis of the output nozzles 12 are directed tangentially to the surface of the housing or close to it at an acute angle. The device operates as follows: In the lower part of the gas scrubber housing, water or other irrigation fluid is poured to a normal level, which is heated by means of the overflow device 5. Then the irrigation fluid is fed to the nozzle 3. After that, a gas containing impurities of dust or harmful gases is introduced into the gas scrubber through the device 2 for the introduction of contaminated gas. The irrigating liquid is supplied to coagulate the dust on the liquid droplets, inject the necessary reagents into the scrubber and compensate the consumption of the irrigating liquid for the removal of the captured product as its concentration increases. The contaminated gas enters through the collet 9 of the cap into the cap 8, changes direction and hits the mirror of the liquid. A large number of splashes are formed in the gas impact gas shock fluid that penetrates the entire mass of air. A part of them is deposited, another is captured by the air flow and with it rushes into the window 13 of the pocket 11 in the form of a gas suspension, which then goes out through the output 4 of the pipe 12 into the internal volume of the aerosol and gently hits the cylindrical wall of the housing 1, followed by vakrutkoy flow. As a result of hitting the wall, as well as as a result of swirling flow, water particles are deposited on the wall and drain into the lower part of the device, where they are mixed with the spray liquid. The cleaned gas enters the windows 7 of the nozzle 6 and is discharged from the device through the upper or lower branch, depending on the layout. Excess irrigation fluid is continuous & but it is removed from the gas scrubber through the pipe 4 with the help of the overflow device 5. The leakage of the crude gas from the cap 8 into the internal volume of the apparatus, the pocket, is prevented by the fact that the bottom wall of the pocket 11 is located above the lower edge of the cap water seal. Due to the soft blow of the gas-spring against the wall, the kinematic energy of the rectilinear flow emerging from the pocket 11 is converted into the energy of the rotational motion. Claim 1. Gazoochistitel, which includes a housing, a hopper for collecting irrigation liquid, a device for introducing contaminated gas, nozzles for discharging cleaned gava and waste liquid, characterized in that, in order to reduce flow resistance, increase cleaning efficiency and reduce bruising, the device the gas inlet is equipped with a bell and with vertical slits, pockets placed in the cracks and having outlet pipes, the axes of which are directed under the acute angle of the inner surface to The body is at the same time the bottom wall of the pocket is located above the bottom edge of the hood and is made with an OTW version in the cavity of the hood. 2. The gas cleaner according to claim 1, wherein the hood is rectangular in shape, and the upper walls of the kappa and the pockets are inclined.
