Arrangement method of demister in exhaust gas purification device

Abstract

The invention discloses an arrangement method of a demister in an exhaust gas purification device. The demister comprises a guide wall formed from a demister and an exhaust gas purification device box, a spraying washing pipe and a washing nozzle arranged above or above in side of the demister. The arrangement method utilizes a side inclined arrangement method of the demister to replace the traditional container top arrangement method. The demister is arranged at the included angle of the side plate and the top plate of the box and is connected to the side plate and the top plate. The demistercomprises one or more demister devices arranged on the same plane in parallel. The arrangement method effectively reduces the space occupied by the demister, increases the flowing area of the demister, reduces the particle size of droplets obtained by the demister, has a simple structure and saves investment.

Description

1. Technical field [0001] The invention relates to an arrangement method of a demister in an exhaust gas purification device, in particular to an arrangement method of a corrugated plate demister. 2. Background technology [0002] The demister is a commonly used equipment in the exhaust gas purification device. During the operation of the exhaust gas purification device, a large amount of water mist will be generated in the front-end treatment process. The pH and moisture content of the water mist will seriously affect the operation effect of the subsequent process. After passing through the demister After demisting, the exhaust gas can enter the next purification process. [0003] The traditional demister is arranged on the top of the exhaust gas purification device, or a demist tower is installed separately. [0004] The demister is installed on the top of the exhaust gas purification device. The demister system is composed of the demister and the spray flushing pipe abov...

AI Technical Summary

Problems solved by technology

[0004] The demister is installed on the top of the exhaust gas purification device. The demister system is composed of the demister and the spray flushing pipe above. The exhaust gas directly reaches the demister from the bottom of the equipment. Since there is no resistance in the middle, the exhaust gas The flow rate is large, and the collision of droplets in the exhaust gas is not very violent, resulting in a decrease in the demisting efficiency. In addition, the spray flushing pipe above the demister is generally about 800mm away from the demister, which increases the height of the exhaust gas purification device and reduces the cost. also greatly increased

[0005] Separately set the demister of the demister tower. The demister system is composed of the demister and the spray pipe above. greatly increased cost
