Cyclone tube type electrostatic precipitator and cyclone tube type electrostatic precipitation equipment

Abstract

The invention provides a cyclone tube type electrostatic precipitator and cyclone tube type electrostatic precipitation equipment and belongs to the technical field of dust collection. The cyclone tube type electrostatic precipitator comprises an electrostatic precipitator housing, a plurality of cyclone tubes and a sound wave back flushing device. An upper partition plate and a lower partition plate which are used for dividing the inside of the electrostatic precipitator housing into a first chamber and a second chamber are arranged inside the electrostatic precipitator housing; each cyclonetube is arranged inside the second chamber and one end of each cyclone tube penetrates through the upper partition plate and extends into the first chamber; the other end of each cyclone tube penetrates through the lower partition plate and extends out in a direction far away from the first chamber. Each cyclone tube is provided with a cathode wire which is connected with a power supply device. The sound wave back flushing device is arranged at the electrostatic precipitator housing corresponding to the first chamber. The electrostatic precipitator provided by the invention integrates cyclonetube dust collection with electrostatic precipitation, realizes higher dust collection efficiency by virtue of the back flushing and oscillation and sound waves, and does not need manual dust removalor maintenance. The dust collection equipment comprising the electrostatic precipitator is higher in dust collection efficiency and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of dust removal, and in particular to a cyclone electric dust collector and cyclone electric dust removal equipment. Background technique [0002] Gas dust removal usually includes gravity dust removal, cyclone dust removal, electric dust removal, and bag dust removal. However, gravity dust removal is usually used for primary dust removal with large particles. The dust removal efficiency of cyclone dust removal can reach about 70%, and bag dust removal can only be used for low temperature. In the environment of 200 ℃, simple electrostatic precipitator is expensive and occupies a large area, which is easy to cause the cathode line to become hypertrophic and the anode plate to accumulate dust, resulting in a decrease in the dust removal efficiency of the electric field.

[0003] At present, the dust removal equipment has but not limited to the following disadvantages: the functions of cyclone dust removal and electric dust removal are formed between the cyclone cylinder and multiple groups of needle-punched corona wires, and the function of dust removal by the core tube is almost lost, and it becomes an air outlet pipe, because its structure It is difficult to judge the direction of the gas in the swirling part of the core tube, and it has almost become a decoration for dust removal. The corona wire is set on the periphery of the core tube, and the core tube acts to prevent the rotation of the air flow. Therefore, the corona wire and the The dust on the periphery of the core barrel is difficult to fall, which will easily cause the cathode line to become hypertrophic, and dust will accumulate on the periphery of the core barrel, resulting in a decrease in the dust removal efficiency of the electric field.

Or, the set return pipeline has no power source for return, and the possibility of return is almost non-existent. Moreover, the dust is prone to turbulence, and the dust removal effect may be worse
