Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment for chemical production, and in particular relates to a waste gas collection and purification device based on chemical production. Background Art

[0002] Waste gas refers to the useless gas discharged by humans in the process of production and life, especially in chemical plants. The reactants, intermediates and products involved are mostly toxic and harmful substances, and the reactions involved are mostly exothermic reactions, which ultimately produce a lot of waste heat, a strong irritating smell, and seriously pollute the environment and affect human health. For this reason, a waste gas collection and purification device based on chemical production is needed. The existing waste gas collection and purification device converts waste gas into waste liquid by spraying, and completes the waste gas treatment after runoff separation of the waste liquid. However, in actual use, during the spraying process, some gases cannot be fully dissolved in the sprayed liquid water, which ultimately results in poor waste gas collection and purification effect. For this reason, we propose a waste gas collection and purification device based on chemical production. Utility Model Content
