[0002] Wet electrostatic precipitator is a new dust removal equipment used to deal with trace dust and microparticles. It is mainly used to remove dust, acid mist, water droplets, aerosols, odors, PM2.5 and other harmful substances in humid gases. It is an ideal equipment for controlling atmospheric dust pollution.

[0003] When removing dust from high-temperature dust-laden gas, the high-temperature gas needs to be cooled first. However, the cooling work is affected by many factors, and it is easy for the dust-laden gas to have a temperature that is too high when entering the wet electrostatic precipitator. When the dust-laden gas enters the wet electrostatic precipitator and the temperature is too high, it will lead to low dust removal efficiency and easily cause damage to the wet electrostatic precipitator. The existing wet electrostatic precipitator cannot intercept the high-temperature dust-laden gas in time, so it needs to be improved. Utility Model Content

[0013] (1) This device can intercept the over-temperature dust-containing gas in time to prevent the over-temperature dust-containing gas from entering the wet electrostatic precipitator body.

When the temperature is too high, the drive motor 5 drives the interception plate 7 to rotate and close, so as to prevent the high-temperature dust-containing gas from entering the wet electrostatic precipitator body 1.

[0023] Working principle: When using the temperature limiting interlock device of the wet electrostatic precipitator, the dust-containing gas that has been cooled first enters the interior of the air inlet pipe 2. At this time, the temperature sensor 6 detects the temperature of the dust-containing gas. If the temperature is within the set value of the temperature sensor 6, the dust-containing gas enters the interior of the wet electrostatic precipitator body 1 for dust removal. If the temperature of the dust-containing gas is higher than the set value of the temperature sensor 6, the drive motor 5 is started, and the drive motor 5 drives the interception plate 7 to rotate, so that the interception plate 7 slowly intercepts and closes the air inlet pipe 2. When the drive motor 5 is started, the gear 9 on the outer wall of the drive motor 5 pushes the gate plate 3 to slide inside the circulation pipe 4 through the rack 8 during the rotation process. The gate plate 3 moves to the rear end of the circulation pipe 4, thereby opening the circulation pipe 4, and allowing the gas inside the air inlet pipe 2 to return from the circulation pipe 4 to the cooling equipment for secondary cooling.
