Technical Field
[0001] This utility model relates to the technical field of gas exhaust devices, specifically a corrosive gas exhaust device. Background Technology
[0002] Wastewater treatment workshops need to monitor the accumulation of corrosive gases online. Therefore, it is necessary to ventilate the workshop to remove these corrosive gases. During the ventilation process, the corrosive gases need to be filtered and discharged.
[0003] For example, announcement number CN113318507B (titled "A Sustainable Recyclable Wastewater Gas Filtration Device") includes a filter device main support and a base. The surface of the filter device main support has several receiving grooves evenly spaced around its axis, extending downwards through the lower end face of the filter device main support. Simultaneously, a post is integrally formed at the center of the lower end of the filter device main support, passing through a corresponding mounting slot in the center of the base. The filter device main support and the base are fixedly connected by bolts. The edge of the base and three sides of the receiving grooves together form a four-sided receiving groove. A cylinder for holding filter media is installed inside the tank. The cylinder is connected to a rotating cover plate via a fixed bracket. The lower end of the rotating cover plate is hinged to the surface of the base via a pin. The edge of the rotating cover plate covers the edge of the receiving tank, and the two are fixedly connected by screws. An output through hole is opened downward at the top of the main support of the filter device, which is located directly above the receiving tank. Input through holes are also opened in the area of the receiving tank on the base. A trigger opening mechanism is installed at the position of the input through hole. The input through hole is opened after the rotating cover plate is closed, so as to realize the sewage gas entering from the bottom up.

When filtering and purifying acidic or alkaline gases, the filtration effect is poor, resulting in a high degree of pollution when corrosive gases are emitted. Therefore, we provide a corrosive gas discharge device. Utility Model Content
