The invention relates to the means of combined cleaning of dust and gas emissions carried away into the atmosphere and can be used in the chemical, metallurgical, mining and other industries, for example, to capture any dispersion and concentration of dust and wet - any concentration of insoluble and soluble in a liquid reagent. fine dust and gases, as well as for automatic overload and accumulation of trapped dust and gas components into collections under vacuum.

The purpose of the invention is to increase the efficiency of gas dusting, to expand the functionality of the plant due to the accumulation of dust of various fractions, of any concentration, and to reduce dropletitis.

assembled from layers of a sieve with a layer of thin foam rubber with a closed apex, facing down, fixed to the surface of the pipeline, and with a base to the rim of a hinged removable cover 22 of the apparatus 6, an outlet 23 for connecting the drop catcher with a booster, and gauge glass 24 with pointers the lowest (LL) and the highest (LL) levels of solution standing in apparatus b, collection 25 for accumulating pulp, stop valves: 26 for sampling pulp and its drain 27 for pouring liquid reagent, sampling the solution and its drain, suction pipe BKA 28 for suction from the duct 29 of the dust-gas mixture. In addition, there is also an inlet pipe 30 and a device 31 for sampling and instrumental measurements.

The installation works as follows.

In the foam apparatus 6, through the valve 26, liquid reagent is poured to the kainite level of the liquid (NU gauge glass 24). The intake tube 28 is placed in the flue 29.

The mover is turned on, a vacuum is created in the installation, elastic valves-shutters 2 and 4 are flattened, attracted to the bulkheads of the neck 5 and overlap these necks (hoppers) of chamber 1 and cyclone 3.

When the driving device is turned on and the unit operates in the laboratory mode of the technological process, the suction of the dust-gas (emission) mixture components begins with the intake pipe 28 from areas of different size, for example, the circular section of the duct 29.

With the passage of dust and gas flow through the device 31, samples are taken to determine the content of dusty components, gas and a set of instrumental measurements (temperature, speed, volume, humidity, etc.).

Then, the dust-gas flow enters the inlet pipe 30 into the inertial cochlear chamber 1, where a large fraction of dust is captured into the bunker, then the floating dust passes from the chamber into cyclone 3, where the average fraction of dust falls into the bunker, and the fine dust fraction and gases pass through the pipeline 7 from the cyclone 3 come under the foaming element 8 of the apparatus 6 with a liquid reagent. Here, as they pass through the nozzle with tip 12 with the ejecting effect of the vacuum flow of the dust-gas mixture on the liquid reagent, the mixture with the reagent moves through the screen of the screen of the truncated cone 10 into the outer foaming element 13 and is intensively mixed, and the process of suppression and separation ends, and
