The invention relates to air scrubbers from suspended particles and can be applied in chemical, textile and other industries in the purification of air used for recirculation from fire and explosive organic and synthetic dust.

The purpose of the invention is to improve the efficiency of air purification and fire and explosion safety.

FIG. 1 shows a dust collector circuit; general view; fig 2 is the same., in operation, when the energy level decreases; in fig. 3 - node I in FIG. 1.

Dust collector contains case 1, with inlet 2 and outlet 3 nozzles, partitions 4 and 5, droplet separator 6 “Case 1 is partially filled with liquid, and in its lower part it is

A discharge outlet 7 for removal of sludge, an overflow pipe 8 with a main tank in the form of a tank 9 with an overflow pipe 10 and a mobile strap 11. The housing is also equipped with a branch pipe 125 in communication with the atmosphere, a branch pipe | 3 for clean water dogs. Partitions 4 and divide the court with 1 into compartments 14 and .- dusty and dust-free air. The partition 4 is fixed to the upper part of the corgus 1, and its part is partially submerged in the liquid, the partition 5 is partially placed in the liquid and acts as the upper part above its level. The partition 4 is provided in its lower part from the side of the compartment 14 of dusty air with a catchment tray 16 with openings 1 / in the bottom (Fig. 2). Vertical film-forming plates 8 mounted parallel to the partition 4 are fixed under the openings 17 to the bottom of the tray. a drop catcher b partition 4 of the sleep section; holes 19 to drain the captured water into the catchment tray 16 (Fig. 2); the gap 20 between the bulkheads 4 and 5 has a Venturi pipe profile. The partition 5 is made hollow and provided with openings 21 (FIG. 2) in the constricted portion of the gap 20. The cavity of the partition 5 communicates with the disk through the openings 22 in the lower portion. Above the gap 20 to the partition 4 is attached the separator 23 in the form of a sloping visor. Nozzle I am installed at the level of water overflow from compartment 15.

Dust collector works as follows.

Under the action of the vacuum created by the aspiration system fan, the water level in compartment 14 of housing 1 decreases, and in compartment 15 it rises between the water surface and the lower edge of the partition 4 and plates 18, a gap is formed through which the cleaned air entering the housing through the inlet 2S passes into the gap 20 where it comes into contact and is rinsed with water entrained by it, as a result of which it is cleaned of dust. The cleaned air bends around the droplet binder 23 and through the droplet separator 6 and the nozzle 3 passes into the recirculation duct or is released into the atmosphere. Water held up in the drift catcher 6 through holes 19 of the stee - kaet across the wall of the partition 4 into the tray 16, where through the holes 17 it hits the plates 18 and flows down in the form of a film, the stream of dusty gas intersects. Due to the fact that the gas flow intersects several film water curtains, an intensive dispersion of phases is ensured with a constant renewal of the contacting surfaces, which creates optimal conditions for the water. dust has been collected and its sediment removed. ZTR of gas flow around the lower edges of the plates, the latter acquire oscillatory movements (vibrate), which leads to dispersion of the film and improve the wetting of dust. In the case of making the gap 20 in the form of a cross section of the pipe, the flow of humidified gas, passing through the constricted part creates a vacuum in this place, under the influence of which water through the holes 22, the cavity of the partition 5 and holes 21 is sucked in and sprayed in the gas flow This increases the efficiency of gas cleaning from dust.

In case of dust ignition on machines or suction air ducts connected to nozzle 2, the dust collector that is in working condition is a reliable flame arrester, since flame propagation is possible only to the surface of the water in the dusty air compartment. Further spread of the flame is impossible, since the burning dust particles are almost completely

are trapped in gap 20 between persoods 4 and 5, and the burning gases are cooled and moistened upon contact with

WATER. In cases where the aspiration aspiration system is switched on when the dust collector is not filled with water to the required level, the aspiration system sucks the air from the room in which the dust collector is installed through the safety pipe 12 as having less resistance than the pipe 2. The air that passes through the narrowed part of the gap 20, due to the vacuum in this place, draws through the holes 22 located at the bottom of the casing 1, then through the cavity and the openings 21 water remaining on the bottom of the casing 1, and sprays it. Accidentally trapped burning particles from nozzle 2 are moistened and extinguished by sprayed water. During the operation, the dust collector at the required water level, with the dust absorbed by it, is poured over the upper edge of the partition 5. Dust collected, depending on its density and wettability, is immersed in water and discharged as sludge through the nozzle 1 or floats to the surface of the water and output through the nozzle 8 fitted with a water seal. The upper water level in compartment 15 is set using the movable strip 11. The drainage of polluted water (sludge) is compensated for by supplying clean water from the water supply system through the nozzle 13.

The technical and economic efficiency of the proposed dust collector is to improve the quality of air purification up to 15–20% by increasing the intensity of dust wetting when a stream of dusty air passes through several film water curtains formed during the discharge of waste water through the film-forming plates and the gap between the partition wall.

MI, the implementation of which in the form of a cross section of the Venturi tube provides for the spraying of the aspirated fluid. This increases fire and explosion hazard due to spraying of BREEDS in the gap between the plates in the event of a significant decrease in the water level from normal due to the possibility of water being sucked for spraying between the plates of the IC under the very bottom of the case through the holes located on the bottom end of the hollow partitions.
