Description

Technical Field

[0001] The utility model relates to the field of curing agent reaction kettle purification, in particular to a curing agent reaction kettle-based purification device. Background Art

[0002] During the manufacturing process of the curing agent in the curing agent reactor, a lot of waste gas will be generated, which pollutes the environment, has adverse effects on human health, and has a certain odor. The waste gas is discharged from the reactor waste gas pipe. Most of the waste gas discharged is volatile organic compounds (VOCs). Long-term exposure to an environment containing high concentrations of VOCs will cause poisoning and carcinogenic tumors. Furthermore, VOCs in the atmosphere will produce photochemical reactions, leading to increased ozone concentrations in the atmosphere and the production of highly oxidizing pollutants. Therefore, these waste gases containing volatile organic compounds must be treated before discharge and cannot be discharged directly into the atmosphere to avoid causing environmental damage;

[0003] The most commonly used purification method for volatile organic compounds (VOCs) is thermal destruction, which decomposes volatile organic compounds (VOCs) into low molecular weight compounds or completely converts them into harmless substances by heating. However, after the volatile organic compounds (VOCs) waste gas is heated by the thermal destruction method, the exhausted gas is still a high-temperature gas and cannot be discharged directly. If it is cooled by cooling equipment, it will not only increase energy consumption, but also make it difficult to recycle the heat energy of the high-temperature gas. Utility Model Content
