Abstract

The invention provides a disposal method and a device used for disposing explosion waste gas, consisting of a separator, a high-efficiency filter, a molecular sieve drier, a NOx adsorbing device, a NOx reducer, a burner, a deodorizer, a circulation fan, an electric heater, etc. The disposal method of the invention comprises the steps as follows: a: waste gas disposal process: the explosion waste gas is disposed by a cyclone filter, the high-efficiency filter, a molecular sieve dehydrator, the NOx adsorbing device and the deodorizer, burned by entering the burner and is exhausted; b: system inerting process: the air feeding of the waste gas disposal device is cut off, nitrogen is filled into the system so as to lead the oxygen content to be less than 2%; c: desorption and reducing process:the circulation fan is started; gas circulation between the circulation fan, the gas electric heater, the NOx reducer and the NOx adsorbing device is established, the reducing gas is filled into the system, the gas electric heater is started, the temperature of the circulation gas is gradually increased, the NOx is de-adsorbed and reduced as N2. After continuous running, the content of the NOx achieves the exhaust standard requirement.

Description

technical field

[0001] The invention relates to a treatment method and device for explosion waste gas, in particular to a treatment method and device for waste gas generated in an explosion experiment. Background technique

[0002] Based on the purpose of civil and military industries, explosion experiments are often required. After the explosion experiments, a lot of exhaust gas is produced, which contains various substances that are harmful to the environment and ecology or fire hazards, such as: heavy metal aerosols, NOx, CO, H 2 , CO 2 、CH 4 In the past, these explosive products were directly discharged into the atmosphere, causing harm to the environment. For example, heavy metals in heavy metal aerosols may be absorbed by plants and enter the human food cycle and accumulate, thereby causing damage to the surrounding human body. Health damage, NOx accumulation in the atmosphere produces acid rain (fog), etc. In addition, the explosion products have peculiar smell, the...
