The flue gas treated by this wet electrostatic precipitator is the flue gas at the yellow phosphorus furnace front, which contains highly corrosive media such as sulfur, phosphorus, arsenic, and fluorine. A flow equalization device is equipped at the inlet of the demister to ensure that the flue gas can flow through the electric field better and more evenly. The material of the flow equalization device must meet the operating environment requirements of the wet flue gas after desulfurization. The power supply of the entire system is designed with a PLC automatic control system, which automatically controls spraying and cleaning. Meanwhile, the PLC system reserves a communication interface, and all data can be uploaded to the DCS control room.

A wet electrostatic precipitator (WESP) for tail gas treatment of calcium chloride was recently dispatched by road to a customer in Shandong Province. This unit is a new additional order from the Shandong customer, as the previously purchased WESP for calcium chloride granulation has achieved excellent operational results. We will subsequently follow up on the on-site installation and commissioning progress.
