Inertial vortex dust collector for wet cleaning of dusty gas

The invention relates to a technique for cleaning gas from dust suspended in it by contacting a dust and gas stream with a liquid, for example, water, and can be used in various industries, for example, in cleaning dust with vapors of chemicals and gases adsorbed on it.

A vortex inertial dust collector is known for wet cleaning of dusty gas from dust suspended in it, containing a cylindrical body, two tangential inlet pipes, an upper axial exhaust pipe, a lower central inlet gas pipe with a swirl, a cowl, a device for supplying water in the form of a pipe and a distribution disk and a hopper for collecting dust and water (see the description of the invention for the USSR copyright certificate No. 835467, IPC VO1D 45/12, publication 07.06.81).

A disadvantage of the known dust collector is the lack of cleaning efficiency. The objective of the claimed utility model is to increase the cleaning efficiency.

The essence of the utility model is that in an inertial vortex dust collector for wet cleaning of dusty gas from dust suspended in it, containing a cylindrical body, at least one tangential inlet pipe for dusty gas, an upper axial exhaust pipe, a lower central inlet gas pipeline with a swirl, a fairing , a device for supplying water and a hopper for collecting dust and water, a device for supplying water is made in the form of nozzles installed in the housing tangentially along the flows of the gas-dust mixture and bottom with at least two diametrically opposite sides of the body.

The essence of the utility model is illustrated by the drawing, where in FIG. 1 shows the inventive dust collector, a General view in section. An inertial vortex dust collector for wet cleaning of dusty gas from dust suspended in it, as well as dust containing chemical vapor, contains a cylindrical body 1, tangential inlet pipe 2 for dusty gas, the lower central gas inlet 4 with swirl 5, fairing 6, a device for feeding water in the form of nozzles 7 installed in the housing 1 tangentially along the contaminated gas and dust mixture from above and nozzles 8 installed from below tangentially along the contaminated gas and dust mixture. The nozzles 7 and 8 are located on two diametrically opposite sides of the housing 1. The dust collector has a hopper 9 for collecting dust and water.

The dust collector works as follows:

Dusty gas enters from below through the central inlet gas pipe 4 into the housing 1 and is twisted by a swirl 5. A tangentially dusty gas is supplied to the inlet through the inlet pipe 2. Water for irrigation of the gas flow enters through nozzles 7, tangentially from two diametrically located sides of the housing 1. Water entrained by the gas flow sprayed in the housing 1, washing the dust particles, moistens them, which contributes to their adhesion into conglomerates, and also dissolves the chemicals adsorbed on the dust particles.

Another part of the liquid (water) is sprayed from below through nozzles 8 also located tangentially from two diametrically opposite sides of the housing 1. Water enters the swirl 5 under the cowling 6, is actively sprayed along the housing 1 and, together with the dusty gas supplied through the lower central inlet gas pipe 4, moves in the housing 1 towards the flow of gas supplied from above. The gas is cleaned of dust with the simultaneous washing of dust from chemicals that dissolve in water. Dust particles settle in the hopper 9, which also receives water with dissolved chemical compounds. The purified gas is discharged through the upper axial exhaust pipe 3.

The water supply to the nozzles is regulated in such a way as to provide the necessary time for the dust to contact the water to wet the dust particles and absorb the vapors of chemical compounds carried away with dust from technological equipment (not shown in the drawing).

Water with dissolved chemical products and settled dust from the hopper 9 is fed into an intermediate tank (not shown in the drawing) and can be sent for neutralization, or again fed into the housing 1 of the vortex inertial dust collector for irrigation.

The inventive device vortex dust collector was tested during the cleaning of wood dust, containing; formaldehyde-containing; its compounds from the processes of manufacturing woodworking products.

In the dust collector D 1500 mm. a gas-dust mixture was supplied in an amount of 30,000 with a dust content of 1174 mg / m, formaldehyde E-5

140 mg / m. After cleaning, the dust content was 23.48 mg / m, formaldehyde 1.29 mg / m.

Thus, the design of the dust collector can significantly increase the efficiency of cleaning.
