Abstract

FIELD: ventilation.

SUBSTANCE: device comprises a housing 1 in the form of a hollow cylinder with exit holes, a pallet 6, a water supply tool. Inside the housing, a rotating shaft 2 with a water supply cavity is installed, on which the inclined blades of the aerosol fan 3, the impeller 5, and the set of grids 4, oriented transversely to the aerosol flow, are serially installed and secured. The impeller is made in the form of four hollow tubes with holes at the ends. The pallet is installed on the side of the set of grids. Rotation of the shaft is due to the energy received from the explosive water effervescence, when it leaves the holes at the ends of hollow tubes.

EFFECT: ability to purify the air from aerosols at any place due to its mobility; the possibility to use in case of fire to precipitate smoke in order to improve visibility.

Description

The invention relates to devices for cleaning air from aerosols, and in particular to devices for the deposition of aerosols.

The problem of air purification is solved using various devices (precipitation chambers, cyclones, acoustic method of aerosol deposition, various filters, etc.), united by a common problem - the impossibility of their use in fires in order to improve visibility in smoke, due to the stationary devices , or insufficient productivity, or the difficulty of implementing the deposition method.

Known invention related to devices for cleaning and processing emissions "High-speed centrifugal spray mixing grid for the exhaust pipe." It consists of a rotating spray pipe; bushings of the shaft, inclined blades and spray mesh. The shaft sleeve is fixedly mounted on the spray tube. Inclined blades are mounted on the front of the shaft sleeve. The spray net is located on the rear of the shaft. Spray holes directed to the shaft sleeve are located on the side wall of the spray pipe. Many inclined spray grooves are located on the side wall of the shaft sleeve. The technical result of the invention is the possibility of delaying the flow of air flowing along the inner wall of the pipe, which ensures appropriate contact of emissions with the wall of fog created by the spray grid, which ensures cleaning of emissions.

The closest in technical essence and the achieved effect is a device for draining and cleaning steam-gas mixture (SU No. 1181691 dated 12/30/1983). The device includes a housing with covers. Inside the case there is a perforated chipper. The device also includes a Venturi pipe with a static flow swirl, an irrigation water collector, nozzles for supplying a contaminated vapor-gas mixture and water, and a nozzle for draining used irrigation water and impurities. The device allows to increase the degree of drainage and gas purification. However, the device has a complex structure and can not be used as a mobile device, as well as to capture fine aerosols and used to precipitate smoke in a fire in order to improve visibility.

Taking into account the problems of the inability to use existing devices for the deposition of smoke in a fire in order to improve visibility, the object of the invention is to provide the necessary zone of visibility in a fire.

The technical result of the invention is the ability to clean the air of aerosols anywhere due to its mobility, as well as the possibility of use in a fire for the deposition of smoke in order to improve visibility.

To achieve the claimed technical result, the aerosol deposition device comprises a housing, a tray and means for supplying water. According to the invention, the housing is made in the form of a hollow cylinder with outlet openings. Inside the casing there is a rotating shaft with a water supply cavity on which inclined fan blades for aerosol supply are mounted and fixed sequentially, an impeller made in the form of four hollow tubes with holes at the ends, and a set of grids oriented transversely to the aerosol flow. The pallet is installed on the side of the grid kit. The rotation of the shaft is carried out due to the energy received from the explosive boiling of the supplied water when leaving the holes at the ends of the hollow tubes.

The invention is further illustrated by an example of a specific implementation of the device and the drawings, in which:

FIG. 1 is a schematic illustration of an aerosol deposition apparatus;

FIG. 2 is a schematic illustration of the impeller of a device.

As shown in FIG. 1, the aerosol deposition device consists of a housing 1 made in the form of a hollow cylinder 1, a shaft 2 with a water supply cavity installed inside the housing 1 using hinges (not shown in the drawing), which allows the shaft 2 to rotate freely. On the shaft 2, inclined fan blades 3, an impeller 5 and a set of grids 4 are sequentially mounted and rigidly fixed. The impeller 5 (Fig. 2) is made in the form of four hollow tubes installed at an angle to each other with holes at the ends. A set of grids 4 for increasing the degree of aerosol deposition should contain at least two grids installed parallel to each other and across the flow of the deposited aerosol, namely across the hollow cylinder. In the lower part of the housing there are openings for the exit of air cleared of aerosol. The housing is installed on the pallet 6, while the pallet 6 is placed on the side of the set of grids 4.

The device operates as follows. The device is installed in a smoky room and a shaft 2 with a cavity is connected to a source of heated water, while water should be supplied under pressure from 2 to 20 MPa and have a temperature of 100 ° C to 300 ° C. Water in the direction of arrow 7 (Fig. 1) is supplied through the shaft 2 to the impeller 5. The tubes of the impeller 5 have openings at their ends, and when water exits the openings of the impeller tubes 5, explosive boiling occurs and the formation of temperature-activated water. Due to the energy of explosive boiling, the shaft 2 begins to rotate, on which the inclined blades 3 and the mesh 4 are rigidly fixed. Due to the rotation of the inclined blades 3, smoke inside the body 1 is sucked up, which is an aerosol. Inside the case 1, the temperature-activated water is mixed and aerosol particles are mixed, as a result of which the mixture is deposited on the grid set 4. Under the action of centrifugal forces, the deposition products are discarded on the periphery of the grid set 4 - the grids self-clean, the precipitation products flow down the walls of the housing 1 in pan 6, and the cleaned air goes back into the room through the holes in the lower part of the housing 1 in the direction of the arrow, as shown in FIG. one.
