Wet scrubber is a device used to pre-treat exhaust gas, which can indirectly improve the efficiency of exhaust gas treatment. Due to the washing of exhaust gas inside the wet scrubber, it can reduce the dust and water-soluble chemicals in the exhaust gas, which can reduce the burden of vocs exhaust gas treatment equipment. , to improve the efficiency of exhaust gas purification.
Generally, in the exhaust gas treatment, there are steps such as collecting gas - pre-washing exhaust gas - transporting exhaust gas - purifying exhaust gas - exhaust gas, and wet scrubbers can be said to play the role of pre-washing and inspection in the vocs exhaust gas treatment process. Such as biological deodorization, exhaust gas deodorization and other projects have an important role. In the treatment of paint, water-soluble waste gas, dust particles, etc., due to different chemical compositions, it has an impact on the treatment efficiency and energy consumption of vocs waste gas treatment equipment. The wet scrubber is used as a pretreatment device to eliminate these unstable factors and improve the smooth operation and purification efficiency of the vocs exhaust gas treatment equipment. In some special cases, when the temperature of the exhaust gas collection inlet is high, the inorganic acid gas generated needs to be cooled to enter the subsequent process during the treatment of the catalytic combustion equipment, and the wet scrubber can be used as a cooling facility and can be widely used in different exhaust gas treatment. in the project.
When dealing with odors and odors, those irritating gases will produce toxic components, which have a great impact on human health; but some are soluble in water, such as ammonia, sulfide and other gases, these odors After washing by the wet scrubber, the treatment efficiency of microorganisms in the biological deodorization equipment will be increased, and the load will be reduced; at the same time, the humid internal environment of the wet scrubber will discharge the odor into the biological purification equipment, which can improve the living environment of microorganisms. Greatly improve the efficiency of microbial deodorization. Therefore, wet scrubbers are also suitable for biological deodorization, and are widely used in waste gas treatment projects such as biological deodorization, biological trickling filtration, biological filters, and UV photolysis.
Wet scrubber structure
The structure of the wet scrubber is a reverse packing absorption tower; due to the light volume of the gas, the gas enters the waste gas scrubber from the bottom of the tower body, and then evenly rises to the packing area, and then undergoes water pre-washing treatment to reduce the solubility in the waste gas For water and dust, the gas is mixed with mist water to form a filter layer on the surface of the tiny droplets to simply treat the vocs waste gas. Among them, in the structure of the wet scrubber, the air velocity and residence time of the superficial tower section are the key factors of the wet scrubber in the VOCs waste gas treatment. The external structure of the wet scrubber is made of PP and stainless steel, and the bottom is also equipped with a water tank for water supply. The size of the water tank is determined according to the spray volume and the number of cycles; there is a packing layer in the middle, and the number of filling layers is selected according to the specific situation; the upper layer is provided with a defogging layer , used to separate the droplets carried by the exhaust gas, and the pretreated gas enters the exhaust gas treatment equipment for exhaust gas purification.、
