Abstract

The invention discloses a dustproof device for an electrostatic precipitator. The dustproof device comprises a cleaning long triangular body and a cleaning angle iron, wherein the cleaning long triangular body is formed by welding three rectangular plates and two triangular plates, and is provided therein with a cavity; the cleaning angle iron is connected with at least one triangular plate, and is also connected with a rapping striking rod on the lower edge of an anode plate in the electrostatic precipitator. The cavity in the cleaning long triangular body is designed to reduce the weight ofthe cleaning long triangular body and reduce the manufacturing cost. The dustproof device can prevent the dust with poor fluidity from accumulating in the electrostatic precipitator by the cleaning long triangular body, and avoids a dust accumulation phenomenon, so that the cathode plate and the anode plate in the electrostatic precipitator cannot be subjected to a short circuit due to the accumulation of dust. The dustproof device can completely solve the dust accumulation caused by the deterioration of the dust fluidity inside the electrostatic precipitator when the flue-gas temperature at the inlet of the electrostatic precipitator is lowered from 110 degrees centigrade to 90+ / -2 degrees centigrade, so that the dust cannot accumulate at the lower part of the cathode plate in the electrostatic.

Description

technical field [0001] The invention relates to an anti-dust device for an electric dust collector, which belongs to the field of electric dust removal equipment. 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 and reduce the amount of smoke and dust discharged into the atmosphere. It is an important environmental protection equipment to improve environmental pollution and air quality. [0003] At present, the coal-fired thermal power unit of the power plant has undergone ultra-low emission transformation of flue gas, and a low-temperature economizer is installed in front of the electrostatic precipitator to make the electrostatic precipitator a low-temperature electric precipitator. The flue gas temperature at the inlet of the electrostatic precipitator equipped with a low-low temperature economizer is 110°C, and the flue gas te...
