PP acid mist spray tower

PP acid mist spray towerIt is an equipment for purifying acid mist waste gas. During the process of sulfuric acid, nitric acid, hydrofluoric acid, hydrochloric acid and other processes, acid/alkaline gases are generated. The waste gas enters the high-efficiency packed tower through the power of the induced draft fan, and the absorption liquid is evenly distributed on the packing at the upper nozzle of the packed tower. The waste gas and absorption liquid are fully in contact on the surface of the packing. Due to the high mechanical strength, corrosion resistance, high porosity, and large surface area of the packing, there is a large contact area and reaction time between the waste gas and absorption liquid on the packing surface. The purified gas will be saturated with water and discharged directly into the atmosphere after being removed by the mist removal device at the top of the tower. The working principle of the acid mist treatment tower is to separate pollutants from the gas and convert them into harmless substances to achieve the purpose of purifying the gas. It belongs to the differential contact counter current type, and the packing inside the tower is the basic component of gas-liquid two-phase contact. After the gas outside the tower enters the tower, the gas enters the packing layer, which has a layer of liquid film from the top spray liquid and the front spray liquid, and forms a liquid film on the packing. When the gas flows through the gap of the packing, it contacts the packing liquid film and undergoes absorption or comprehensive reaction. The packing layer can provide a sufficiently large surface area without causing excessive resistance to the gas flow. The absorbed or comprehensive gas is collected by the demister and discharged outside the tower through the outlet. The wastewater is treated with chemicals in the acid mist purification tower circulation pool before being recycled, and the sediment is regularly cleaned and transported outside.

The PP spray tower mainly consists of a tower body, nozzles, packing layer, circulating pump, and electrical control system. The tower body is mostly circular or square, with a packing layer inside. A nozzle is installed above the packing layer, and the circulating pump evenly sprays the absorbent onto the packing layer through the nozzle. The electronic control system mainly controls the start and stop of the circulating pump and adjusts the working pressure of the nozzle.

PP acid mist spray towerMainly used for treating dust and toxic waste gases generated in industrial production. If these exhaust gases are directly discharged into the atmosphere without treatment, they will cause serious harm to the environment and human health. The PP spray tower achieves the purpose of purifying exhaust gas by fully contacting it with liquid through spraying.

The PP spray tower is made of polypropylene (PP) material, which has good corrosion resistance and can resist the erosion of chemical substances such as acid and alkali. It is suitable for treating various corrosive waste gases. PP spray tower adopts modular design, compact structure, and easy installation; Meanwhile, the sprinkler system is easy to disassemble and clean, with low maintenance costs, ensuring the long-term stable operation of the equipment.

PP spray tower, as an important waste gas treatment equipment, is widely used in industrial production. It plays a crucial role in exhaust gas treatment with its structure and efficient processing capability
