Description

Technical Field

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

[0002] Waste gas treatment refers to the adsorption, filtration and purification of waste gas generated in the industrial production process. In the process of extracting and purifying the waste gas, a ventilation device is needed to convert the gas inside the space where the waste gas is generated to avoid excessive waste gas volume affecting the health of operators. After searching the application number CN202221042447.1, a high-power ventilation treatment equipment for dissipated organic waste gas in a spraying workshop was found. It records that the blower sucks in fresh air from the outside through the blower external unit, and then overflows from the air hole. After the suction device is started, it absorbs the air in the workshop, and the blower delivers air and inhales air. The device inhales air to form a circulation layer. When the rising air contacts the circulation layer, it will be quickly sucked away by the suction device. After entering the suction device, it enters the filter device through the suction pipe. The filter in the filter device will block the dust in the air, and the air will become pure. However, the above description still has the following defects in actual use: the current ventilation device used for exhaust gas purification treatment relies solely on the suction structure and the blowing structure to discharge the gas in the internal space, and lacks a structure to assist ventilation. At the same time, there is a lack of filtering device for harmful gases during the ventilation process. Therefore, it is necessary to design a ventilation device with strong practicality for exhaust gas purification treatment. Utility Model Content
