Spray tower is a common waste gas treatment equipment, and its structure includes the following main parts:
1.Tower body: The tower body is the main structure of the spray tower, which is usually made of carbon steel or glass fiber reinforced plastic. The shape of the tower body is cylindrical or square, and the interior is equipped with packing layer, nozzle, spray layer and other components. The design of the tower body needs to consider the flow, temperature, composition and other factors of the exhaust gas to ensure that the exhaust gas is fully treated in the tower body.
2.Packing layer: The packing layer is an important part of the spray tower, and its main function is to increase the contact area between the exhaust gas and the spray liquid and improve the treatment efficiency. The filler layer is usually made of plastic, ceramic and other materials, and has different shapes, such as corrugated plates, granules, etc. The design of the packing layer takes into account factors such as the characteristics of the exhaust gas, the treatment effect and the operating cost. 3.Nozzle: The nozzle is a key component in the spray tower, and its main function is to evenly spray the spray liquid on the packing layer. There are many types of nozzles, and the right nozzle can be selected according to factors such as the characteristics of the exhaust gas, the treatment effect, and the operating cost. The nozzle should be installed in a position and angle that is carefully designed to ensure that the spray fluid evenly covers the packing layer. 4.Spray layer: The spray layer is another important part of the spray tower, which is mainly used to store and recycle the spray liquid. The spray layer is usually made of carbon steel or glass fiber reinforced plastic, and there are circulating pumps, liquid level gauges and other equipment inside. The function of the circulating pump is to pump the spray liquid out of the reservoir and spray it on the packing layer through the nozzle, while ensuring the circulation of the spray liquid. The function of the level gauge is to monitor the level of the spray fluid so that it can be replenished in time. 5.Defogging layer: The defogging layer is the last component in the spray tower, and its main function is to remove water mist from the exhaust gas. The defogging layer is usually made of plastic or fiberglass, and there are equipment such as defoggers inside. There are many types of mist eliminators, such as louver type, wire mesh type, etc., and the appropriate mist eliminator can be selected according to the actual situation. The setting of the defogging layer can improve the treatment effect and operational stability of the spray tower. Spray tower exhaust gas treatment equipment
