The invention relates to a technique for cleaning gases from solid, liquid and gaseous impurities and can be used in any sector of the national economy in the wet cleaning of gases in irrigation scrubbers, foam apparatus, etc.

The purpose of the invention is to improve reliability by ensuring the stability of drop-collecting in all gas streams passing through the apparatus.

Figure 1 shows the apparatus section; figure 2 - section aa in figure 1; Fig. 3 is an embodiment of the device with the closed (tightly adjacent or welded to the body) end of the gas exhaust pipe.

The apparatus includes a housing 1, equipped with a nozzle 2 of the gas inlet and a gas outlet nozzle 3. In the lower part of the housing 1 absorbent devices 4 are placed (in this case irrigation nozzles). A drop-breaking guide grating 5 with plates 6 symmetrically inclined from the center is installed above them. The nozzle 3 is installed with a minimum clearance (5-10 mm) to the wall of the housing 1, which, due to the large resistance, eliminates the release of undressed gases and provides drainage on the inner walls pipe 3 liquid. To improve the flow of the pipe 3 can be installed not only horizontally (as shown in Fig.), But with a slope in the direction opposite to the output end. In the upper part of the nozzle 3 there is a longitudinal slit 7 above which the eccentric shaft 9 with the handle 10 is mounted for rotation around the axis 8. The ribs 11 are fixed on the outer surface of the nozzle 3. The plates 12 fixed to the body 1 are inserted between them. The ribs 11 and the plates 12 tilted toward the loose edge. Above the plates 12 along the edge fixed on the housing 1, collectors 13 are placed.

The end of the pipe 3 can also be closed, i.e., tightly abut or be welded to the housing 1. In this case, holes 14 are provided for draining the accumulated liquid from the cavity of the pipe 3.

The device works as follows.

Through the nozzles 4 in the apparatus serves irrigating fluid. At the same time through the pipe 2 enters the purified gas. Upon contact with the falling particles of the irrigating liquid, the absorption of harmful impurities from the ascending gases and at the same time their moistening occur. Part of the droplets is separated by a droplet throat grating 5. When

further upward movement of gases pass

through a maze of ribs 11

and plates 12, additionally dried, through the slit 7 is fed into the pipe 3 and

out of the apparatus.

The eccentric shaft 9 in the device is necessary to adjust the size of the slit 7 during operation of the device. Such adjustment is necessary, since the process parameters (the magnitude and temperature of the gases to be cleaned, their humidity) can vary. A reduction in the gap leads to an increase in the resistance of the apparatus (ie, to an increase in the energy consumption for its operation), and an increase in the gap to a deterioration in the drop-detection. Therefore, the operators select the gap gap, which, given the parameters of the gas, provides the required gas drying by the regulations with the lowest hydroresistance of the apparatus. It follows that the implementation of a predetermined slit value without installing an eccentric shaft narrows the possibilities of stable drop-recovery when changing the parameters of the gas flow. The installation of the eccentric shaft solves the problem of operative adjustment of the gap size.

Periodically through the collectors 13 serves washing fluid, cleaning the growths from the ribs 11 and plates 12.

The use of the proposed apparatus allows to increase its reliability by ensuring the stability of trapping moisture droplets with harmful impurities in all gas streams passing through the apparatus, thus reducing environmental pollution.

The average degree of drift recovery reaches 98%. At the same time, there are no significant deviations from the average parameter throughout the entire cross section of the gas outlet pipe, t, e, of the gas slip with lower exponents

drip drop.
