Then the flue gas goes up to the dust screen layer, and the dust particle in the flue gas is kept below the dust screen by the separation of dust screen. Then, the flue gas passes through the dust screen and reaches the spraying layer, sulfur dioxide, nitric oxide and the like in the flue gas collide with alkaline substances in the circulating liquid and generate chemical reaction, and the generated waste is adhered to water drops and sinks to the bottom of the tower body. Along with the downward falling of the liquid drops on the spraying layer, the waste accumulated at the bottom of the tower body is discharged. The whole tower body has a simple structure, is convenient to operate, fully plays the role of water, and can well treat pollutants in flue gas.
2) The liquid supplementing pipe is connected with the water inlet pipe through a two-way pipe and is respectively injected, a switch valve is arranged on each straight pipe to control flow, adjust the concentration of the alkaline solution and improve the purification effect.
3) The bottom of the circulating liquid pool is inclined towards the liquid outlet, so that impurities at the bottom of the pool can be conveniently and quickly discharged through the liquid outlet, the solution can conveniently flow, and slag at the bottom of the pool can be conveniently removed.
