The research shows that: PM2.5 is mainly derived from high-temperature combustion of coal, is the most toxic component in smoke, can adsorb various toxic substances, and can reach the lung through a respiratory tract, even enter a blood system, so that cardiovascular diseases and other diseases are caused. Under the background that the state requires further improvement of the flue gas emission standard and high importance is placed on PM2.5 treatment, the electric precipitation of the power plant behind the desulfurization island is a trend. The electric dust removing system can be divided into a dry electric dust removing system and a wet electric dust removing system. The wet electric dust collector is a high-voltage electrostatic dust collection device for treating moisture-containing gas, and is an ideal device for treating atmospheric dust pollution, mainly used for removing dust, acid mist, water drops, aerosol, odor and PM2.5 in the moisture-containing gas.

The main forms of the device include a plate type and a tube type.
The main process flow of the horizontal wet-type electric dust collector is that dust-containing flue gas passes through an inlet flue and enters an electric field through a flow equalizing pore plate, electrons are discharged from a cathode wire under the action of high-voltage electricity in the electric field, high-speed electrons strike surrounding flue gas molecules to generate more free electrons so as to generate electric collapse and generate corona discharge, the free electrons are attached to flue gas dust and move to a dust collecting electrode under the action of the electric field force, and dust moving to the dust collecting electrode is taken away by a water film on the dust collecting electrode to complete the dust collecting process. And the flue gas enters the outlet flue after passing through the demister after the electric field dust removal is finished. The cathode system is the most important component for generating corona and establishing electric field, and determines the intensity of discharge. The performance of the charge of the dust in the flue gas is influenced, the dust removal efficiency is directly related, in addition, the strength and the reliability of the system are also directly related to the safe operation of the whole electric dust remover, and therefore, a corona electrode system is a key part for designing, manufacturing and installing the electric dust remover. Good line shapes and reasonable structures must be chosen. And a strict pole spacing is ensured during installation, and the good insulation performance and the sufficient discharge distance of the whole corona pole system and other parts of the electric dust collector are ensured.
The problem that the flashover frequency of a cathode system is increased due to splashing of water drops often occurs in actual operation, and the direct expression of the operation is that the flashover occurs when the secondary voltage rises to a lower voltage, so that the secondary voltage cannot be kept at a higher level, and the dust removal performance is deteriorated.
