Wet electrostatic precipitator to prevent fouling of anode tubes

Abstract

The invention relates to a wet-type electric dust remover capable of preventing anode pipes from scaling. The wet-type electric dust remover comprises a shell. A gas inflow chamber, a gas distribution chamber, an anode chamber and a gas outflow chamber are sequentially arranged in the shell from bottom to top. The gas inflow chamber is provided with a gas inlet. A gas distribution board is arranged in the gas distribution chamber. The anode pipes are evenly distributed in the anode chamber. Cathode lines are suspended in the anode pipes respectively. A gas outlet is formed in the top of the gas outflow chamber. An insulation box is arranged on the shell. The wet-type electric dust remover is characterized in that a liquid collection box is arranged at the bottom of the gas inflow chamber and connected with a first circulating pump and a second circulating pump. A second spray pipe is arranged at the top of the gas inflow chamber and connected with the first circulating pump. An upper water carrying board and a lower water carrying board are arranged in the anode chamber and an overflow pipe is arranged on the upper water carrying board and connected with the second circulating pump. Water collection grooves are formed in the lower ends of the anode pipes and water outlets are formed in the pipe walls of the anode pipes. The shell is provided with water outflow pipes and the water outflow pipes are lower than the water outlets. By the adoption of the wet-type electric dust remover, crystals on the inner walls of the anode pipes can be removed in real time, scale is prevented from being generated, and it is guaranteed that the dust removing efficiency of equipment is not affected.

AI Technical Summary

Problems solved by technology

However, when the wet electrostatic precipitator is running, there is an electric field between the anode tube and the cathode line, if a large amount of water passes through, it is easy to cause a short circuit and damage the equipment

Therefore, this method can only be carried out when the wet electrostatic precipitator is out of service

At the same time, due to the long-term accumulated scale thickness and area are often large, it is difficult to completely remove it by this method, and the residual scaling on the anode tube wall will affect the electric field effect between the anode tube and the cathode tube, causing equipment Decrease in dust removal efficiency
