[0002] Coking refers to the process of heating coking coal to about 1000℃ in an airtight environment to produce coke, coke oven gas and other coking chemical products through thermal decomposition and coking. The waste gas produced by coking contains sulfides and nitrates, which will pollute the environment if discharged directly.

[0003] The exhaust gas is treated by the desulfurization and denitration tower. The exhaust gas enters the desulfurization and denitration tower from the bottom inlet of the desulfurization and denitration tower. The exhaust gas passes through multiple spray layers for desulfurization and denitration. The gas after desulfurization and denitration passes through the dewatering mist layer and is finally discharged from the top of the desulfurization and denitration tower. The treated water in the desulfurization and denitration tower flows to the inner bottom of the desulfurization and denitration tower and is pumped out by a water pump for reuse.

[0004] However, the water treated in the desulfurization and denitrification tower contains particulate matter. When it is pumped out through the water pump, these particulate matter will cause certain damage to the inside of the water pump, and even cause damage to the water pump.
