(54) DEVICE FOR OBTAINING A PENISTIC AEROSOL

(57) It relates to the metallurgical industry and can be used to combat dust in air. The purpose of the invention is to increase the foaming efficiency and reduce the power consumption of the device. The air flow supplied to the casing 1 rotates the impeller 2 with rectangular curved blades with holes around the axis of the Impeller 2. At the same time, the rectangular curved blades with holes with a convex side are moistened in the container 4 with the frother solution. Under the action of the air flow, bubbles of foam aerosol are blown out of the holes of the blades when rotating. 2 Il.

The invention relates to the metallurgical industry and can be used to combat dust in the air in the chemical, construction and other industries.

The aim of the invention is to increase the efficiency of foaming and reduce the energy intensity of the device.

FIG. 1 is a schematic diagram of an apparatus for producing a foam aerosol; in fig. 2 is a section A-A in FIG. one.

 A device for producing a foam aerosol comprises a housing 1, an impeller 2 with rectangular curved blades with holes, an axis 3 of the impeller and a container 4 with a foaming agent solution.

The device works as follows.

The air flow supplied to the casing 1 rotates the impeller 2 around axis 3, and the rectangular curved blades with the impeller openings are moistened with a convex side in the reservoir 4 with the foaming agent solution, from the openings of which bubbles rotate under the action of the air flow to blow foam foam.

The proposed device is characterized by simplicity of design with. high dust collection efficiency,

Curved rectangular blades with holes allow bubbles of larger diameter to be blown out, which improves the efficiency of the device.

The absence of the proposed device, the need for supply under pressure of the solution of the foaming agent reduces energy consumption.

The possibility of clogging the holes to form bubbles of foam aerosol is eliminated.

As a source of air flow can be used any ventilation systems, various types of fans.

The proposed device cleans the environment from dust of different dispersity.

Form l, and the invention

A device for obtaining a foam aerosol, comprising a housing with openings for air supply and removal of foam, a container with a foaming agent solution and a device for blowing bubbles, which, in order to increase the efficiency of foam generation and reduce the energy intensity of the device, the device for blowing bubbles is made impeller with perforated curved blades of rectangular shape mounted for rotation and immersion of the blades in a container with a foaming agent solution, The blades are mounted with a concave surface towards the air inlet and a convex one towards the hole for the removal of foam.

Claims (1)

Claim A device for producing foam aerosol, including a housing with holes for supplying air and removing foam, a container with a foaming solution and a device for blowing bubbles, characterized in that, in order to increase the efficiency of foam generation and reduce the energy consumption of the device, the device for blowing bubbles is made in the form impellers with perforated curved blades of a rectangular shape, mounted with the possibility of rotation and immersion of the blades in a container with a foaming agent solution, and installed fall off the concave surface toward the opening of the air supply and convex - toward the opening for discharging foam.
