Dust remover box structure of electric dust remover

Abstract

The invention provides a dust remover box structure of an electric dust remover. The dust remover box structure comprises a dust remover body, wherein the top of the dust remover body is communicatedwith an air outlet cover, the bottom of the dust remover body communicates with an air inlet, the air outlet cover is communicated with a negative pressure fan, the dust remover body comprises a box body and an electrode wire, a plurality of closed insulator mounting boxes are arranged around the box body, insulators are mounted in the insulator mounting boxes, the upper portion of the upper insulator mounting box is communicated with the air outlet cover, the lower portion of the upper insulator mounting box is communicated with outside air, the lower portion of the lower insulator mounting box is communicated with the air inlet, and the upper portion of the lower insulator mounting box is communicated with the outside air. The insulator is mounted in the insulator mounting box, air in the insulator mounting box flows in from outside air and then flows out from the insulator mounting box, and the filtering device is added to filter the air entering the insulator mounting box, so thatthe cleanliness of the air is ensured, and creepage, discharge or temperature rise bursting and other phenomena generated after the insulator is stained with dust are avoided.

Description

technical field [0001] The invention relates to the field of exhaust gas treatment, in particular to a dust collector box structure of an electric dust collector. Background technique [0002] Electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove the particulate smoke and dust in the exhaust gas of combustion stoves or oil-fired boilers, thereby greatly reducing the amount of smoke and dust discharged into the atmosphere, which is to improve environmental pollution. , an important environmental protection equipment to improve air quality, electrostatic precipitator is divided into wet electrostatic precipitator and dry electrostatic precipitator, wet electrostatic precipitator and dry electrostatic precipitator have the same dust collection principle, all rely on high voltage corona The discharge makes the dust charged, and the charged dust reaches the dust collecting plate / pipe under the action of the electric fi...

AI Technical Summary

Problems solved by technology

[0004] 1. The cathode plate and the anode tube should be insulated. The existing method is mostly the anode tube is grounded, and the anode tube is installed on the dust removal box, and the dust removal box is grounded, so as to ensure the safety of the equipment, and the cathode plate is usually through an insulator. Installed on the box, but the working environment of the dust collector is poor and there is a lot of dust. After the insulator is covered with dust, creepage, discharge or temperature rise and burst will occur, causing the equipment to stop

[0005] 2. The existing electrode wires are mostly installed by manual electric welding bolts, and then the electrode wires are installed through the bolts, but the manual welding error is large, which is likely to cause different electric fields and affect the dust removal efficiency

[0007] 4. Conventional electrode wire structures include: tubular prickly wire, sawtooth wire, angle steel prickly wire, spiral wire, star-shaped wire, etc.; existing problems and shortcomings of prickly wire: the gas with dust is in a straight line in the pipe fittings Trajectory, short residence time, low charging contact efficiency, many dusts are not charged; unreasonable structure of the discharge tip, resulting in uneven distribution of corona when the burr discharges at the tip, low charging contact efficiency, resulting in particle escape rate raised

This kind of cleaning method is to clean from top to bottom, and the flushing intensity of the middle and lower parts is insufficient, resulting in the dust on the dust collecting poles (cathode and anode) not being washed down in time, which will cause a drop in operating voltage, corona sealing and local corrosion, etc. question
