Nitrogen oxide waste gas treatment equipment

Abstract

The invention relates to the related technical field of waste gas treatment, and discloses nitrogen oxide-containing waste gas treatment equipment, comprising a main body, an air inlet and an exhaust port are arranged on the main body, a diversion section and an adsorption section are arranged on the main body in sequence, and the air inlet is connected with the air inlet. The diversion section is connected, the adsorption section is provided with a diffusion channel and an exhaust channel, the exhaust channel is connected with the exhaust port, a through hole is arranged between the diffusion channel and the exhaust channel, and several adsorption beds are movably installed in the diffusion channel The adsorption bed blocks the through holes, and the adsorption bed is provided with an adsorbent. Through the setting of the closing component and the baffle, one of the adsorption beds can be pulled out independently. During the pulling out process, the adsorption bed is pulled and closed. The membrane seals the exhaust channel to prevent the exhaust gas in the exhaust channel from being discharged to the outside through the adsorption bed. After the adsorption bed is completely pulled out, the adsorbent in the adsorption bed can be replaced separately at this time, so that no The overall shutdown of the equipment ensures the continuous operation of the equipment and improves the efficiency of waste gas treatment.

Description

technical field [0001] The present invention relates to the related technical field of waste gas treatment, in particular to nitrogen oxide-containing waste gas treatment equipment. Background technique [0002] As the main source of air pollution, nitrogen oxide waste gas has been increasing year by year in recent years. It is not only one of the main sources of acid rain, but also a carcinogen, which can cause photochemical smog and damage the ozone layer. In industrial production The generated nitrogen oxide-containing exhaust gas is generally treated by catalytic decomposition method, solid adsorption method, microbial method, liquid absorption method, etc. The appropriate treatment method is selected according to the composition and properties of the exhaust gas. Among the above treatment methods , Adsorption method is a more commonly used treatment method. The commonly used equipment for adsorption method is adsorption tower.

[0002] As the main source of air pollution, the emission of nitrogen oxide exhaust gas has increased year by year in recent years. It is not only one of the main sources of acid rain, but also a carcinogen, which will lead to the generation of photochemical smog and damage the ozone layer. Industrial production The generated waste gas containing nitrogen oxides is generally treated by catalytic decomposition method, solid adsorption method, microbial method, liquid absorption method, etc., and the appropriate treatment method is selected according to the composition and properties of the waste gas. Among the above treatment methods , the adsorption method is a relatively commonly used treatment method. The commonly used equipment for the adsorption method is an adsorption tower. The waste gas outside the tower body is sent into the tower. The components are absorbed by the adsorbent, and the clean air is discharged from the air outlet to complete the treatment. However, during use, due to the different positions of the adsorbent, the service life of the adsorbent at different positions in the adsorption tower is different. When replacing , there is a problem that it cannot be replaced at the same time, and then, when only part of the adsorbent needs to be replaced, it still needs to be shut down for replacement, which reduces the efficiency of waste gas treatment. In view of the above problems, this application is proposed
