Chongqing waste gas treatment equipment Take you to know the function of spray tower

The acid mist waste gas is introduced into the purification tower through the air duct. After passing through the packing layer, the waste gas and sodium hydride absorbent fully contact with the gas and liquid to absorb and neutralize the gas. After purification, the acid mist waste gas is dehydrated and removed by the dust plate, and then discharged into the atmosphere by the fan. After pressurizing the tower bottom with water pump, spray the absorbent on the tower top and down, and then recycle to the tower bottom. The purified acid mist exhaust gas meets the national emission standard.

Spray tower can also be called washing tower, water washing tower and purification tower, which are commonly used in gas-liquid reaction system Waste gas treatment equipment The waste gas is in reverse contact with the liquid, and the gas can be purified, dedusted, and cooled after washing. At present, it is widely used in industrial acid and alkali waste gas treatment. It can be seen from the keywords of water washing, washing and purification that the main reuse of spray tower is to remove dust and purify the acidity and alkalinity of waste gas.

When we see the spray installed, some spray towers have a large box under them, and some do not. Some people may wonder why they are all spray towers, but how can they be configured differently? This is not surprising. The large box is actually a medicine box. When treating acid and alkali gases, chemical components in the exhaust gas need to be washed away, so medicine must be added. However, the spray tower without large box is actually used to clean the dust and particles in the exhaust gas.

To sum up, in the process of waste gas treatment, the spray tower equipment is basically used because the dust in the waste gas can be relatively large, and the acidity and alkalinity in the waste gas are relatively serious, such as odor. Of course, if the air volume is small, other equipment may also be able to handle it. The air volume is slightly larger than that of Chongqing Waste gas treatment The probability of the exhaust gas treated by the equipment reaching the standard is relatively small.

Industrial acid and alkali waste gas enters the spray tower under the action of fan. In the spray layer of the spray tower, the absorption liquid sprayed by the nozzle is evenly distributed on the packing, and the waste gas and the absorption liquid are fully contacted on the packing surface to react. HCL, NO2, NH3 and other acidic substances easily soluble in water in the exhaust gas are almost all dissolved in the absorption solution and react with the absorption solution to generate harmless salts and water, so as to achieve the purpose of purifying the exhaust gas. The purified gas will be saturated with water, which will be directly discharged into the atmosphere after being removed by Chongqing waste gas treatment equipment. The absorption solution is prepared according to the nature of pollutants and can be recycled.
