Description

The invention relates to devices for wet dust collection and can be applied in all areas of the industry. A device for wet gas cleaning is known, comprising a housing with a conical bottom, an inlet nozzle, a grate, nozzles, irrigations, stationary flush nozzles and a device for removing sludge l3. The disadvantage of this dust collector is that it is not suitable for trapping fibrous, in particular textile dust, due to the fact that when it is used according to the scheme of partial circulation of water, the nozzles and the grid are clogged with fiber, and the cleaning efficiency drops sharply. The closest to the invention in technical essence and the achieved result is a wet dust collector comprising a horizontal pinhole housing, an inlet for air, a nozzle for supplying water and removing sludge 2. A disadvantage of the known device is its unreliable operation during air purification with fiber dust. The purpose of the invention is to increase the versatility and reliability of the dust collector, especially when trapping fibrous materials, simplifying the design, reducing capital and operating costs. This goal is achieved by the fact that a wet dust collector, including a housing, an air inlet, a water supply and a sludge removal nozzle, is equipped with two profiled partitions placed under the water supply nozzle, one of which is movable and the inlet is designed as a confuser, the output edge which is located under profiled partitions. It is advisable to provide the body with a convex flap installed under the confuser and equal to its width, and a spillway tube located above the lower point of the body.

FIG. 1 shows a wet dust collector; in FIG. 2 - the same, top view.

The dust collector includes a round section housing 1, in the upper part of which there is a water supply chamber formed by a part of the housing and profiled blades - movable 2 and fixed 3. The chamber is connected to fitting 4 for supplying water. Under the water supplying chamber, through the wall of the casing, a confuator 5 is inserted, the nozzle of which is located in front of the slit of the water supply chamber. In the bottom of the housing there is a spillway 7 and a sludge settling tank 8, and a drift catcher 9 at the end.

Dust collector works as follows.

Water through the nozzle 4 enters the water supply chamber. Moving profiled blade 2 regulate the uniformity and magnitude of the water supply. The dusty air through the confusor 5 at a rate of 2-ZO m / s is supplied under the water supply chamber, ejects the water flow and breaks it up into small particles. Transportable and the water on the dust is mixed, thrown to the walls of the housing 1, hit them and a water mirror at the bottom of the housing. Further, the flow is twisted by the outer wall of the confuser and the inner wall of the plate 6 and exits into the non-irrigated part of the body 1, where it continues to move and clean. Caught Drone falls into the sludge trap. Passing the drip catcher 9, the air is emitted into the atmosphere or fed to the plant for recycling.

The application of the proposed dust separator will allow you to catch various

types of dusts, including fibrous textile dusts, which clog the dust-separating devices of other dust-separators, for example, bar solutions, and do not wash them off,

In the water supply chamber, the water at a low speed is discharged through a much wider opening than in the nozzles, which eliminates its clogging and increases the reliability of operation. Making the water supply chamber and the whole dust collector is simpler and cheaper.

Claims (2)

1. A wet dust collector comprising a horizontal, cylindrical body, an inlet for air, a water supply nozzle and a sludge removal, characterized in that, in order to increase the versatility and reliability of the operation, to reduce capital and operating costs, the dust collector is equipped with two profiled partitions, one of which is installed with the possibility of movement, and the inlet is made in the form of a confuser, the output edge of which is located under the profiled partition s. 2. A dust collector according to claim 1, which is based on the fact that the body is provided with a convex shield installed under the confuser and equal to its width, and overflow pipe located above the bottom of the hull.
