Problems solved by technology

The spraying method is mainly used to remove particulate matter in the exhaust gas, but the effect of removing particulate matter is not good because the water droplets cannot fully contact the exhaust gas; moreover, this method will also generate waste water, which also needs to be purified before it can be used. emissions, increasing the cost of exhaust gas treatment
The adsorption method can effectively remove various pollutants in the exhaust gas, but many adsorbents can only be used once. Although some adsorbents can be reused many times, they need to be desorbed after the adsorption is saturated. It can be used for adsorption again after attached treatment
The existing desorption method is usually to take out the adsorbate in the adsorption tank and send it to the desorption equipment for desorption treatment, and add new adsorbate to the adsorption tank. This method is inconvenient to operate and low in efficiency

Abstract

The invention discloses a spray booth exhaust gas treatment system based on lime powder circulation adsorption pretreatment. The spray booth exhaust gas treatment system comprises an exhaust gas pretreatment device and an exhaust gas aftertreatment device. The exhaust gas pretreatment device comprises an exhaust gas pretreatment device main body and a first fan. An ash bin is arranged in the exhaust gas pretreatment device main body. Lime powder is arranged in the ash bin. The ash bin is provided with an ash discharge port. The ash discharge port of the exhaust gas pretreatment device main body is communicated with an air inlet of the first fan through a connection pipe. An air outlet of the first fan is communicated with an air inlet of the exhaust gas pretreatment device main body through a connection pipe. An air outlet of the exhaust gas pretreatment device main body is communicated with an air inlet of the exhaust gas aftertreatment device. The system removes particles in exhaustgas through mixing of lime powder and exhaust gas. The lime powder fully contacts with exhaust gas so that the particle removal effects are improved. The first fan realizes recycling of the lime powder and reduces the exhaust gas treatment coat.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment equipment, in particular to a paint spraying room waste gas treatment system based on lime powder circulation adsorption pretreatment. Background technique [0002] Exhaust gas will be generated during the process of painting products in the spray booth. If the exhaust gas is discharged directly, it will cause environmental pollution. Therefore, it is necessary to purify the exhaust gas before discharging it. There are many existing waste gas treatment methods, such as Drenching, adsorption, etc. The spraying method is mainly used to remove particulate matter in the exhaust gas, but the effect of removing particulate matter is not good because the water droplets cannot fully contact the exhaust gas; moreover, this method will also generate waste water, which also needs to be purified before it can be used. Emissions increase the cost of exhaust gas treatment. The adsorption method ca...
