Operation Principle: The lead smoke spray tower utilizes a unique five-stage treatment process. — Stage 1: Lead smoke dust gas enters in a circular motion, with large particles of dust removed by a cyclone separator and dropped into the bottom storage tank, where they are settled through the honeycomb inclined tube treatment. — Stage 2: Gas enters a stage of turbulent porous grid, where the turbulence flows into the packed bed. The fluid comes into full contact with the liquid film for mass transfer, with some dust flowing downstream into the storage tank. — Stages 3 to 4: Gas enters a slot contact purification section, with the gas flow direction differing from the liquid flow, greatly reducing the acceleration of the liquid. It overcomes the triangular jet caused by the concurrent flow of gas and liquid, while maintaining a low and uniform liquid layer within the slots to ensure good gas-liquid contact. This allows for continuous dispersion and aggregation of the gas and liquid, achieving an excellent mass transfer effect.

Air enters the cyclone tower treatment section through slots, with the core part of gas-liquid mass transfer utilizing cyclone plates, which result in higher empty tower velocities. The air stream is rotated as it passes through them, with entrained droplets being thrown toward the tower wall by centrifugal force for separation, then condensed and回流. The air continues through the counter-rotating tower plates, achieving rotational contact in both clockwise and counterclockwise stages. Five-stage Treatment: The gas passes through a carbon adsorption layer, with the mist being adsorbed and dropping down, and some droplets suddenly decelerating and being removed by the cyclone plates at the top of the carbon layer through centrifugal force, expelling clean air into the atmosphere. Applications: Industries where smoke and dust are produced during welding, polishing, cutting, and grinding processes, as well as in the recovery of rare metals and valuable materials. It can purify a large amount of harmful fine metal particles suspended in the air, reducing harm to workers' bodies.
