Nitrogen oxide-containing 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 which comprises a main body, a gas inlet and a gas outlet are formed in the main body, a flow guide section and an adsorption section are sequentially arranged on the main body, the gas inlet is connected with the flow guide section, a diffusion channel and a gas exhaust channel are arranged in the adsorption section, and the gas exhaust channel is connected with the gas outlet. A through hole is formed between the diffusion channel and the exhaust channel, a plurality of adsorption bed bodies are movably mounted in the diffusion channel, the through hole is shielded by the adsorption bed bodies, adsorbents are arranged in the adsorption bed bodies, one of the adsorption bed bodies can be independently pulled out through the arrangement of the sealing assembly and the baffle, and in the pulling-out process, the adsorption bed bodies pull the sealing film, so that the adsorption bed bodies are separated from the exhaust channel. The exhaust channel is closed, waste gas in the exhaust channel is prevented from being exhausted to the outside through the adsorption bed body, and after the adsorption bed body is completely pulled out, the adsorbent in the adsorption bed body can be independently replaced, so that the whole equipment does not need to be shut down, the continuous work of the equipment is ensured, and the waste gas treatment efficiency is improved.

Description

Technical field [0001] The present invention relates to a technical field related to waste gas treatment, specifically nitrogen oxide-containing waste gas treatment equipment. Background [0002] Nitrogen oxide exhaust gas as the main source of atmospheric pollution In recent years, emissions have increased year by year, it is not only one of the main sources of acid rain, but also carcinogens, which will lead to the production of photochemical smog, but also cause a break in the ozone layer, the waste gas containing nitrogen oxides produced in industrial production is generally treated by catalytic decomposition method, solid adsorption method, microbial method, liquid absorption method, etc., according to the composition of the waste gas, nature, etc. To choose the appropriate treatment method, in the above treatment method, Adsorption method is a more commonly used means of treatment, of which the adsorption method is commonly used equipment for the adsorption tower, the exhau...

Problems solved by technology

[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
