TECHNICAL FIELD
[0001] Embodiments of the present disclosure relate to the technical field of high-temperature waste gas treatment, in particular to a waste gas treatment device for recycling high-temperature waste gas. BACKGROUND
[0002] The organic waste gas is first subjected to adsorption by activated carbon or other adsorbents to remove harmful substances, then the adsorbents are subjected to desorption by high-temperature hot air in a desorption area, and finally the desorbed organic waste gas enters an oxidation chamber to fully mix with high-temperature air to generate oxidation reaction, generating carbon dioxide and water to achieve the purpose of purification.
[0003] Since the concentrations of pollutants in waste gas are different, the concentrations of pollutants in some waste gas are relatively high, and those in some waste gas are relatively low. The addition of adsorbents in the adsorption tower on the market is generally based on the concentration of pollutants in waste gas. When the concentration of pollutants in waste gas is relatively high or the flow rate of waste gas is relatively large, the reaction of waste gas with adsorbents will be relatively fast, and it is necessary to frequently add adsorbents. The adsorbents are added through a pipeline connected to the adsorption tower. When a large amount of adsorbents is needed, workers need to frequently add adsorbents. During the process of adding adsorbents, the waste gas treatment device may need to be temporarily stopped, which will affect the continuity of production and reduce the production efficiency.
