Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device used for green synthesis of fipronil. Background Art

[0002] Fipronil is a phenylpyrazole insecticide with a broad insecticide spectrum. It mainly acts as a stomach poison on pests, and also has contact and certain systemic effects. Its insecticidal mechanism is to block the chloride ion channels mediated by γ-aminobutyric acid and glutamate in insects, thereby causing excessive excitement of the insect's central nervous system. During its production process, a large amount of harmful gases will be produced, so they need to be collected and treated.

[0003] The existing waste gas treatment device can refer to the utility model with patent announcement number CN219333747U, which discloses a waste gas treatment device, "including a cyclone dust collector, a desulfurization and denitrification spray tower, an induced draft fan, a spray liquid storage tank and a sedimentation tank; this scheme arranges a venturi tube under the ash hopper, based on the discharge of spray wastewater and the water seal effect, so that when high-speed liquid flows through the venturi tube, the ash powder will be sucked away by the negative pressure, and when there is no high-speed liquid flowing through the venturi tube, the waste liquid accumulated in the venturi tube will be sucked away by the negative pressure. The water seal structure of the ash hopper prevents external air from entering the cyclone dust collector from the ash hopper. Compared with the existing ash discharge valve, the sealing difficulty is lower and the sealing effect is better. The baffle plate can prevent the cyclone from extending into the ash hopper. The anti-rotation baffle plate can prevent the ash hopper from generating associated vortices. The blocking effect of the anti-rotation baffle plate can prevent the generation of a relatively continuous spiral airflow, thereby preventing the ash powder in the ash hopper from being rolled up by the secondary vortex. "But for harmful gases, they need to be treated multiple times before they can be discharged.

[0004] In order to solve the above problems, the present application proposes a waste gas treatment device for the green synthesis of fipronil. Utility Model Content
