Abstract

The invention is intended to separate suspended particles from gas and improves the efficiency of trapping dust from a gas stream. The coronating and precipitating electro-DE1, in the form of truncated cones, are fixed and alternate with each other. The coronation cone is made with slots, and the settling cone with openings in such a way that both the inner and outer surfaces of the sedimentation cone are

dative. The dust-laden gas falls under the corona cone 2 and passes between the slots or plates. At the same time, the particles get charged and, together with the gas, move under the sedimentation cone 3. The charged particles settle on the inner surface of the precipitation cone, and the air with the non-segregated particles passes through the holes and falls under the next corona cone. When passing through the apertures of the precipitation cone 3, the air is braked, partially swirls and, washing the outer surface of the precipitation cone, is deposited on its outer surface. 3 il.

The invention relates to a device for separating suspended particles from gases using an electrostatic effect and can be used in all sectors of the national economy for cleaning gas from pshi.

The purpose of the invention is to increase the efficiency of collecting dust from a stream of times.

FIG. Figure 1 shows a combined electrode for an electrostatic precipitator; general view; in fig. 2 - sedimentary truncated cone; on fig.Z - corona truncated cone.

The combined electrode consists of a non-conductive rod 1, on which corona 2 and precipitating 3 truncated cones are successively assembled. The position of the corona and sedimentary truncated cones between themselves is fixed by bushings 4. At the top and bottom, the position of the truncated cones and bushings is fixed by nuts 5 and 6. The sedimentary truncated cone 3 has a plurality of gas holes on its surface.

A coronal truncated cone 2 has slots on its surface and can be made in the form of a set of separate plates connected into a cone near the truncated vertex. An electric current (not shown) is supplied through a special cavity in the rod 1 by means of a conductor.

Cleaning sedimentary truncated cones can be produced by a known method.

The combined electrode operates as follows.

The dust-laden gas in the electrostatic precipitator moves from the base of the truncated cones, falls under the corona-truncated cone 2 and passes between the slots or plates. At the same time, particles of the material receive a charge and, together with the gas, move under a settling truncated cone 3. The charged particles settle on the inner surface of the settling truncated cone, and the air with non-settled particles passes through the holes and falls under the next corona truncated cone. When passing through the holes in the sedimentary truncated cone 3, the air is braked, partially swirls and washes the outer surface of the sedimentary truncated cone, with some of the particles settling on its outer surface.

With the passage of dusty air through the next corona-truncated cone, the particles that did not manage to receive charges were charged, and those that had already been lost earlier were charged again.

When dusty air passes through a whole series of alternating cones, all particles settle on the inner and outer surfaces of the settling cones.

The proposed combined electrode for electrostatic precipitator allows reducing metal consumption and increasing the efficiency of dedusting up to 99%.
