Problems solved by technology

[0004] The wet electrostatic precipitator is cleaned by intermittent spraying. In order to maintain the cleaning efficiency, a huge water flow rate is required, and it is difficult to clean the electrodes completely. It needs to be shut down for cleaning regularly; in the case of continuous spraying of fine liquid (mist) for cleaning, the Almost all the water is evaporated at the front of the electrode, and there is no way to effectively clean the deep inside of the electrode. If there is too much water when spraying, the efficiency will be reduced due to spark discharge

Abstract

The invention discloses a water film forming device of a horizontal wet electrostatic precipitator. The water film forming device comprises a main spraying pipe arranged on the electrostatic precipitator and further comprises a nozzle mounting head arranged below the main spraying pipe and a nozzle connected with the nozzle mounting head; the nozzle comprises a connecting portion and a liquid spraying cavity arranged below the connecting portion, and a plurality of liquid spraying holes are distributed in the liquid spraying cavity; and according to the water film forming device of the horizontal wet electrostatic precipitator, a stable, continuous and even water film is formed on the surface of a dust collection electrode, the dust is thoroughly prevented from polluting the dust collection electrode fundamentally, and maintaining cost needed by dust collection electrode cleaning is reduced. The spark discharge phenomenon can be restrained, the dust removal efficiency and the running efficiency of the horizontal wet electrostatic precipitator can be wholly improved, and in addition, the water film forming device of the horizontal wet electrostatic precipitator has the beneficial effects of being simple in structure and convenient to mount.

Description

technical field [0001] The invention relates to a water film forming device for a horizontal wet electrostatic precipitator, which belongs to the field of machinery. Background technique [0002] Electrostatic precipitators, especially horizontal electrostatic precipitators, are mainly plate-shaped dust-collecting poles, and a plate with a tapered part or a steel wire with a small diameter is set between the plate-shaped dust-collecting poles as Discharge electrode, and then apply a high voltage to the anode (+) or cathode (-) of the discharge electrode to cause corona discharge to charge the inflowing particle-like substance. In the continuous electric field, the charged particles rely on static The principle of electric power moving to the dust collecting pole and absorbing and removing. [0003] The electrodes of the wet electrostatic precipitator are cleaned with water. The traditional methods are: intermittent spraying and continuous spraying of fine liquid (mist). ...
