Description

A cylindrical electrostatic precipitator

technical field

The utility model relates to the technical field of electric dust collectors, in particular to a cylindrical electric dust collector.

Background technique

Electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove particulate smoke and dust in the exhaust gas of coal-fired or oil-fired boilers. It is an important environmental protection equipment for improving air quality. Its working principle is that when the flue gas passes through the flue in the main structure of the electrostatic precipitator, the dust is charged, and then the flue gas enters the channel of the electrostatic precipitator with multiple layers of oppositely charged plates. Due to the mutual adsorption between the charged smoke and the opposite electrode plate, the particulate smoke in the flue gas is adsorbed on the plate, and the plate is hit regularly, so that the smoke with a certain thickness falls into the ash hopper under the structure of the electrostatic precipitator under the double action of its own weight and vibration, so as to achieve the purpose of removing the smoke in the flue gas.

For example, the Chinese utility model patent with the notification number CN218486256U discloses "an energy-saving cylindrical electrostatic precipitator, specifically related to the technical field of electric precipitators, including a dust removal box. The lower movable plate and the upper movable plate are arranged inside the dust removal box... The utility model drives all the anode tubes to vibrate through the lower movable plate and the upper movable plate, so that the dust on the inner wall of the anode tube falls off is relatively simple and convenient. The deviation of the distance between the poles of the dust collector makes the dust removal efficiency of the dust collector higher."

For the above-mentioned related technologies, the dust on the inner wall of the anode tube is simply moved up and down to make the dust on the inner wall of the anode tube fall off, and some dust with a high viscosity to the inner wall of the anode tube is still difficult to remove, and the cleaning effect on the dust on the inner wall of the anode tube cannot be guaranteed. Therefore, those skilled in the art provide a cylindrical electrostatic precipitator to solve the problems raised in the background art above.

By the cooperation of the motor 11, the driven gear 12 and the driving gear 13, the seal plate 702 can be driven to rotate, and the outlet pipe 8 can be blocked.

Referring to Fig. 1, the cleaning mechanism 9 includes a blower fan 901 and an air pipe 902. The blower fan 901 is fixedly installed on the upper left side of the dust removal tube 1. The air pipe 902 is fixedly connected to the input end of the blower fan 901, and the bottom end of the air pipe 902 penetrates into the inside of the air storage cylinder 6. The cleaning mechanism 9 facilitates supplying air to the air storage cylinder 6 and blows it out through the air outlet pipe 8, so that the dust on the inner wall of the anode tube 5 can be further cleaned.
