Description

(54) DEVICE FOR WET GAS CLEANING OF DUST

This invention relates to the field of wet scrubbing.

A device for wet scrubbing of gases is known, comprising a housing with a guide skirt, inside of which a droplet separator is arranged axially, a foaming agent with a suction diffuser and an impeller mounted on the shaft.

However, the known device is ineffective, consumes a lot of water.

The purpose of the invention is the intersification of the cleaning process and reduction of the device dimensions.

For this, the film former is made of a set of rings installed with an adjustable gap and interconnected by bridges, and the droplet separator is in the form of a reverse truncated cone, to the larger base of which a truncated cone is attached to a smaller base, forming an intake device with a reverse truncated cone.

FIG. 1 shows the proposed device for wet gas cleaning, general view; in fig. 2 is a section along A-A in FIG. one;

in fig. 3 - the same, top view.

In the upper part of the housing 1 of the device for wet cleaning of gases from dust along the suction nozzle 2, which forms the incision, and in the lower part there is a valve 3 for removing the sludge. A skirt 4 is installed in the body, at the bottom of which the forming skirt has the shape of a torus; droplet separator 5, made in the form of two truncated cones inserted one into the other and facing opposite bases in such a way that the large base of the small cone is the small base of the large cone 6. The small cone is rigidly connected to the large cone adjacent the large base to the suction inlet the fan 7, and a small base - to the film maker 8 and is made in the form of a set of zigzag empellers.

The film former 8 has the shape of a cylinder in which annular grooves are formed along a generatrix at a certain distance from one another. In the lower part of the film former, a suction diffuser 9 with a mesh 10 is installed. An impeller 11 is mounted on the elongated wap of the fan.

The device works as follows. When starting up, for example, a grinding machine, a fan is simultaneously turned on. The air to be cleaned enters the housing 1 through the suction nozzle 2, envelops along the defining skirt 4 and through the lower edge of the skirt, made in the form of a torus, passes into the multistage hydraulic cleaning zone formed by the film former 8 Air passed through the cleaning system and falls onto the droplet separator 5, installed at a certain angle, and then through the fan to the exhaust. Separate with. dust in the form of pulp flows into a collection box with a valve 3. When the fan shaft is rotated, at the end of which turbine 11 is mounted, water passes through the grid 10 of the diffuser 9 into the internal cavity of the film former 8, from which, due to centrifugal force and a certain shape of the cross section of the film former, the multi-stage water curtain.

Subject invention

A device for wet gas cleaning of dust, comprising a housing with a guide skirt, inside of which are an axis separator, a film former with a suction diffuser and an impeller mounted on the shaft, characterized in that, in order to intensify the process of dust cleaning and size reduction of the device, the film former is made from a set of rings installed with a regulating gap and interconnected by bridges, and a drop is separated in the form of a reverse truncated cone, to the larger base of which, coaxially a truncated cone is attached to it by a smaller base, which forms an intake device with a reverse truncated cone.
