Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas treatment device of an RTO thermal storage incineration method. Background Art

[0002] The RTO regenerative incineration method itself is an efficient method for treating organic waste gas. Its purpose is to convert organic waste gas into harmless substances such as carbon dioxide and water through high-temperature oxidation to reduce pollution to the environment. Under normal operation and treatment up to standard, the final emissions are mainly carbon dioxide, water vapor and other relatively environmentally friendly gases. However, in the actual operation process, due to some uncontrollable situations, carbon monoxide, nitrogen oxides, acidic gases (SO2, HCl) and particulate matter (particles formed by some ash and other substances produced by combustion) may be produced. These products are not only toxic, but also pollute the environment and endanger human health.

[0003] Most of the existing waste gas adsorption uses activated carbon adsorption. The principle is to rely on the porous structural characteristics of activated carbon to provide a huge specific surface area, so that the organic molecules in the waste gas can adhere to the pores on the surface of the activated carbon, thereby achieving the purification of the waste gas. However, the adsorption capacity of activated carbon is limited. Once it reaches saturation, if it cannot be replaced or regenerated in time, adsorption failure will occur, resulting in the waste gas being directly discharged into the atmosphere without sufficient treatment. Secondly, the regeneration process after activated carbon adsorption is relatively complicated and costly, and usually requires high-temperature desorption, chemical elution and other methods. These regeneration methods are not only difficult to operate, but may also cause secondary pollution during the regeneration process, further affecting the environmental governance effect. For this reason, we propose an RTO thermal storage incineration method for waste gas treatment. Summary of the invention
