Efficient electrostatic dust collector

Abstract

The invention provides an efficient electrostatic dust collector. The efficient electrostatic dust collector comprises a dust collection tube vertically arranged, an air inlet is formed in the lower portion of the dust collection tube, and an air outlet is formed in the upper portion of the dust collection tube; the lower end of the dust collection tube is connected with an ash bucket and an ash discharging valve; a corona wire is arranged on the axis of the dust collection tube; the dust collection tube is electrically connected with a positive electrode of a high-voltage direct-current power source, and the corona wire is electrically connected with a negative electrode of the high-voltage direct-current power source; and the dust collector further comprises a magnetic field generation device, and the magnetic field generation device generates magnetic fields longitudinally distributed in the dust collection tube. According to the efficient electrostatic dust collector, under the same voltage, the ionization degree in the dust collection tube is larger, more free ions exist, rebounding of charged particles can be restrained, and therefore the dust collecting efficiency is improved.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an electrostatic precipitator. Background technique [0002] Electrostatic precipitator is a relatively common type of environmental protection dust removal equipment. Its basic components include corona wires and dust collection pipes; among them, the dust collection pipe is a metal pipe, which is vertically arranged and connected to one pole of a high-voltage DC power supply. The corona wire is set along the axis of the dust collection pipe and connected to the other pole of the high-voltage DC power supply; the lower part of the dust collection pipe is provided with an air inlet, and the upper part is provided with an air outlet; when working, the high-voltage electric field between the corona wire and the dust collection pipe The air in the dust collection tube is ionized, and a small amount of free electrons in the air fly radially to the dust collection t...

Problems solved by technology

[0003] However, there are two disadvantages in this structure. One, because the free electrons and charged dust particles fly straight to the inner wall of the dust collection pipe, a large recoil force will be generated on the inner wall of the dust collection pipe, which makes it difficult to reach the dust collector. After the inner wall of the dust tube, the particles that lose electrons and gain opposite electrical properties return to the dust collection tube under the recoil force, weakening the electric field in the dust collection tube, or flying directly to the corona wire, which affects the corona effect; second, Due to the short flying path of free electrons in the dust collection tube, there are fewer chances for them to collide with air molecules, so that the ionization degree of the air in the dust collection tube is restricted, and the charged amount of dust particles is limited, so the dust removal efficiency is still limited.
