Description

The invention relates to wet dust collecting devices and can be used in dust cleaning and / or air cleaning systems in various industries.

In dust removal systems, dust separation is usually carried out in two stages, while the first stage uses mainly centrifugal dry dust collectors, and the second one uses bag filters or wet dust collectors, and one of the conditions for the effective operation of the latter is the possibility of continuous removal of water contaminated with dust from them (sludge).

Known wet dust collector containing a cylindrical housing, inlet nozzles for introducing a dusty air mixture and water, an outlet nozzle for venting cleaned air, connected by a pipe to a traction inducer, an outlet nozzle for venting sludge connected to a water seal [Baltrenas P.V. Dust removal of air at building materials enterprises. M .: Stroyizdat, 1990 - p.122].

The disadvantage of such a dust collector is that the water trap is prone to rapid clogging due to the deposition of dust particles on the bottom and walls of the water trap.

Known wet dust collector containing a cylindrical housing, inlet nozzles for introducing a dusty air mixture and water, an outlet nozzle for removing cleaned air, connected by a pipe to a traction inducer, an outlet nozzle for removing sludge connected to a water seal [Donat E.V. Pneumatic dusting in the shops of industrial enterprises. M .: VTsSPS Profizdat, 1960 - p.130]. The water seal is made in the form of an open sump and the removal of sludge can be carried out continuously.

The disadvantage of this device is that at the bottom of the valve there is a rapid accumulation of a layer of dust particles, which tends to

self-compaction and an increase in the height of the layer with time, which leads to the overlap of the cross section of the pipeline.

Known wet dust collector containing a cylindrical housing, inlet nozzles for introducing a dusty air mixture and water, an outlet pipe for removing cleaned air, connected by a pipe to a traction inducer in the form of a liquid ring vacuum pump, an outlet pipe for removing sludge, connected by a pipe with a water seal equipped with a pipe for supplying additional water in a pulsating mode from the traction stimulator to the bottom space of the hydraulic seal [Certificate of the Russian Federation for utility model No. 27899, cl. B01D 47/02, 2003].

This dust collector has a limitation due to the fact that the pulsating mode of supplying additional water can only be carried out using a liquid ring pump, and the presence of a pipeline of considerable length immersed in a water trap increases the height of the dust collector.

The task to which the proposed utility model is directed is to ensure the operational reliability of the dust collector by expanding the functionality of the hydraulic seal.

This problem is solved in that in a wet dust collector containing a cylindrical housing, inlet nozzles for a dusty air mixture and water, an outlet nozzle for exhausting cleaned air, connected by a pipe to a draft inducer, an outlet nozzle for removing sludge connected to a water seal, the latter contains at least one the U-shaped elbow is made of a flexible tubular element, connected to the outlet pipe to discharge sludge by means of a corrugated tubular element and equipped with means for shaping Nia water seal, its vibration, sludge level control in the conical part of the wet dust collector, siphoning and changing the flow cross section of the flexible tubular member.

The means for shaping the hydraulic lock can be made in the form of brackets, one end of each of them is fixed on the hydraulic lock, and the other on the console.

The means for vibrating the valve can be connected to the corrugated tubular element.

Means for regulating the level of sludge conical part of the wet dust collector can be made in the form of a rack - level gauge.

The presence of at least one U-shaped elbow in the trap eliminates the possibility of breakthrough of atmospheric air into the volume of the wet dust collector.

The implementation of the hydraulic lock from a flexible tubular element allows you to give it any shape during the process of setting its operating mode.

Connecting a water trap to the outlet pipe to discharge sludge by means of a corrugated tubular element allows you to use the capabilities of this element from the point of view of it as a rotary elbow.

The supply of a hydraulic lock means for its shaping makes it possible to fix the optimal shape.

The supply of a water trap with a means for vibrating it makes it possible to improve the transportation of sludge and to prevent its deposition.

Providing a water trap with means for regulating the level of sludge in the conical part of the wet dust collector makes it possible to adjust its operating mode depending on the operating conditions of the dust collector itself.

The implementation of the means for shaping the hydraulic lock in the form of brackets, one end of which is mounted on the hydraulic lock, and the other on the console, allows you to use the capabilities of simple and reliable suspensions.

The connection of means for vibrating the hydraulic lock to the corrugated tubular element provides a pumping effect at the inlet of the sludge in the latter.

The implementation of the means for regulating the level of sludge in the conical part in the proposed utility model of a wet dust collector in the form of a rack - level gauge provides simplicity, convenience and speed of adjustment.

The utility model is illustrated by drawings, which depict:

figure 1 - wet dust collector with a water seal, General view;

figure 2 - water seal with one U-shaped elbow with suspension elements;

figure 3 - water seal with two U-shaped elbows;

figure 4 - corrugated tubular element;

figure 5 - elements of a water trap with means for regulating the level of sludge in the conical part of the wet dust collector;

The wet dust collector contains a cylindrical housing 1 with a nozzle 2 for introducing dusty air, a nozzle 3 for introducing working water, a nozzle 4 for venting cleaned air connected through an elbow 5 to a pipe 6 with a traction inducer (not shown), a nozzle 7 for venting sludge connected to the corrugated tubular elements 8 with a water seal 9. The latter contains at least one U-shaped elbow, is made of a flexible tubular element and is equipped with means for shaping the water seal, its vibration, and adjustments sludge level in the conical part of the wet dust collector.

The means for shaping the hydraulic lock can be made in the form of brackets 10 of adjustable length, one end of each of them is fixed to the hydraulic lock 9 using, for example, a clamp 11, and the other, for example, on the console 12 (or traverse, etc.).

The vibrating means (not shown in FIG.) Of the hydraulic lock 9 (a vibration exciter of any known design can be used as this means) can be connected to the corrugated tubular element 8 and acts on it through a system of springs 13 tightened by flanges 14.

The means for regulating the sludge in the conical part of the wet dust collector can be made in the form of a rack - a level gauge 15 along which a horizontal bracket 16 can be moved, fixed at one end on the rack 15 using a latch 17, and the other on the shutter 9 with a clamp 18.

To change the bore of the flexible tubular element, an adjustable clamp of any known construction can be used (not shown in FIG.).

Wet dust collector operates as follows.

Polluted air (usually from the first stage of dust collection, where cyclones are used) enters through the inlet pipe 2 into the housing 1, where water is simultaneously supplied through the inlet pipe 3. As a result of the process, the dry cleaned air is discharged from the housing 1 from above through the pipe 4, then along the elbow 5 and through pipeline 6 to the traction stimulator, from which it is released into the atmosphere.

Dust particles trapped by water enter the lower (conical) part of the housing 1, where through the nozzle 7 and the corrugated tubular element 8 are discharged in the form of sludge into the hydraulic seal 9.

A water trap 9, having at least one U-shaped elbow, facilitates the removal of sludge through its discharge end at a speed provided by the flow of water to trap the dust entering the pipe 3.

The corrugated element 8 during operation of the wet dust collector is subject to compressive forces - decompression, while improving the process of hydrotransport of sludge through the hydraulic seal. This effect can be enhanced by connecting this element to a vibration actuator, which forcibly acts on the element, as well as on the hydraulic lock through a system of springs 13, mounted on the flanges 14.

The hydraulic shutter shaping system can be used to intensify sludge hydrotransport using one or several brackets 11 spring-loaded or elastic.

Regulation of the level of sludge in the conical part of the housing 1 depending on its density, the required discharge rate, etc. produce by moving up and down the discharge cone of the hydraulic lock 9 relative to the rack - level gauge 15.
