Abstract

The invention relates to the wet cleaning of gases with the use of surfactants, can be used in the woodworking industry for cleaning ventilation emissions from dust of polyester varnishes and allows to increase the reliability of work and reduce energy consumption. The device includes a housing (K) 1, the lower part of which is filled with liquid, the upper 2 and lower 3 partitions forming a slotted channel (impeller), a droplet separator 4 with baffle plates (OD), gas inlets and outlets 6 and 7, drain pipe 8, a supply tank 9 for supplying components with hydrophilic properties, a tank 11 for components with hydrophobic properties, connected by a main through channels and openings to the outer surfaces of the OP. Dust gas enters through pipe 6 at K1, passes an impeller, where it interacts with a liquid with a surfactant solution, and is directed through drip catcher 4 to the outlet pipe 7. The passage between the OD, the gas is released from the droplet moisture, which wets them and does not stick, and flows down in the form of drops in the lower part of K1, 4 Il.

Description

with a liquid with a surfactant solution, and is directed through the drip tray to the outlet nozzle 7. The passage between the OP, the gas is freed from droplet moisture, which, falling on the OP, does not wet them and does not stick, but drains into the lower part K 1 . il.

The invention relates to the scrubbing of gases from poorly wettable dusts using surfactant solutions and can be used in various branches of the national economy, in particular, in the woodworking industry for cleaning ventilation emissions from dust of polyester varnishes.

The purpose of the invention is to increase the reliability of work and reduce energy consumption by eliminating the overgrowth of the dust separator plates.

FIG. 1 shows a wet dust collector, a general view; in fig. 2 is a section A-A in FIG. one; fig. 3, embodiments of the component supply to the surface of the fender plates.

The wet dust collector comprises a housing 1, the lower part of which is filled with liquid, the upper partition 2 and the lower partition 3 partially submerged in the liquid, which are fixed with the slotted S-shaped channel (impeller), drip catcher + with baffle plates 5, supply pipes 6 and gas outlet 7, the drain pipe 8, the supply tank 9 with a metering device

10dl components with hydrophilic properties (for example, Sulfasid-31 according to Specification 6-А487-79), an additional tank 11 with a metering device 12 for antifoaming components with hydrophobic properties (for example, a pressure relief device according to Specification 6-02-892-, level gauge the device 13, the water supply control device 1. The baffle plates 5 comprise channels 15 and holes 16, communicated

with line 17 connecting tank

11 with the outer surface of the plates. Wet dust collector works

in the following way.

The dust-laden gas enters through the inlet pipe 6 into the housing 1 and rushes into the slotted S-shaped channel 17 between the partitions 2 and 3, entrains the liquid. Pass

through the channel, the gas stream collides with the liquid, dust particles under the action of inertial forces penetrate into the liquid layer and are trapped by it. This is facilitated by a surfactant solution containing components with hydrophilic properties (for example, the wetting agent Sulfasid-31). From the tank 11 with the metering device 12 the defoaming component with hydrophobic properties (for example,) is continuously supplied through the pipeline to the channels 15 of the fender plates 5 of the drip catcher A. From the channels 15 through the holes 16 this component flows to the surface of the fender plates 5 and under the influence of the gas flow spreads over the entire surface in a thin layer. When a gas stream passes through a droplet separator, the liquid droplets containing dust collected in it fall on the surface of the baffle plates with a hydrophobic layer, lose speed and flow down to the bottom of the casing as droplets. In this case, the hydrophobic properties of the component (e.g. EAE-AO) are used. The excess component flows through the baffle plates into the lower part of the housing, where it mixes with the liquid and the component coming from the tank 3 and performs the direct functions of the anti-foaming agent, thus forming a solution providing a high degree of dust collection.

The cleaned and dried gas is discharged through the nozzle 7, and the dust collected by the liquid is periodically removed through the drain nozzle 8. When the liquid level drops below the level specified as a result of the sludge discharge, the level gauge 13 turns on the fresh water supply unit 1.

The use of the proposed technical solution allows at least a 30% reduction in operating costs associated with the periodic cleaning of the drip tray plates from dust adhering to them, and avoiding the growth of hydraulic resistance.
