Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation devices, and in particular relates to a ventilation device for treating painting waste gas. Background Art

[0002] The existing studio is used for spraying operations. The space in the workshop is closed, and a large amount of toxic waste gas will accumulate in the air, seriously affecting the health of the workers. Among them, the "a kind of high-power ventilation treatment equipment for dissipated organic waste gas in a spraying workshop" disclosed in the application number "CN202221042447.1" is also an increasingly mature technology. The blower and the suction device are controlled by a remote control. The blower inhales 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. The hair dryer delivers air, and the suction device inhales air, thus forming 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, so that the air will become pure. However, the device still has the following defects: during the ventilation process, simple air supply and ventilation will disrupt the movement direction of toxic substances in the air. Toxic substances float in the air, and it is impossible to effectively reduce the dust of toxic substances and reduce the content of toxic substances in the air. Utility Model Content
