SU1228882A1 - Wet dust trap - Google Patents

Description

The invention relates to gas cleaning of gases from poorly wettable dusts using solutions of surface-active substances (PVA) 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 degree of dust collection and reduce energy costs.

FIG. 1 shows the wet scrubber of FIG. 2 — node I in FIG. one.

The device includes a housing 1, the lower part of which is filled with liquid, the upper partition 2 and the lower partition 3 partially immersed in the liquid, fixed to it, forming between each other a slotted S-shaped channel (impller), a collector 4, inlets 5 and outlet 6 for gas and a drain nipple 7. The bottom partition 3 of the slotted channel contains heating elements 8, and through-channels 9 are made in the part immersed in this partition, passing through the heating elements 8. The surface of the lower partition 3 is convex abzhena heat torus 10.

The device works as follows.

The dust-laden gas flows through the feed pipe 5 into the body 1 and rushes into the slotted S-shaped channel formed by the upper 2 and lower 3 partitions, which carries the liquid. Fluid entrained in the gas stream flows onto

the surface of the lower partition 3, where it mixes with the heated liquid ejected from the lower part of the housing 1 through the through channels 9 passing between the heating elements 8. Partially heated liquid flows with a thin turbulized flow along the surface of the lower partition 3 and is heated by the heating elements 8 to the optimum temperature.

The dusty gas flow, the passage through the S-shaped slit channel, collides with the surface of the heated fluid, the particles ache under the action of inertial forces penetrate into the fluid layer and are trapped by it. This contributes to the surfactant solution, heated to the optimum temperature. The purified gas passes through the drop catcher 4, where it is released) from drip moisture. The cleaned and dried gas is discharged through the pipe 6, and the dust collected by the liquid is periodically removed through the pipe 7.

Thus, a thin turbulized layer of liquid flows over the surface of the lower partition of the S-shaped channel, where the dust collects mainly, heated to the optimum temperature and provides a high degree of dust collection while economically using energy to heat the liquid directly involved in the dust collection process.

In the dust collector, only that part of the liquid that is directly involved in the cleaning process is heated.
