This invention relates to the field of laboratory gas treatment equipment technology, specifically a low-noise automated ventilation and purification device for hazardous gas chemical laboratories. The device includes a ventilation mechanism, which comprises a mounting plate. An outer cover is fixedly connected to one side of the mounting plate, and a filter cleaning mechanism is fixedly connected inside the outer cover. The filter cleaning mechanism is connected to the mounting plate through a ventilation opening, which is located on the mounting plate. A rotating mechanism is located above the filter cleaning mechanism. In this invention, the activated carbon particles at the ventilation opening lose their methane adsorption capacity after prolonged use. Therefore, when the motor starts, it drives the activated carbon particles on the lifting plate, the activated carbon particles on the rotating plate, and the filled activated carbon particles to deflect as a whole. This causes the activated carbon particles that were previously far from the ventilation opening and had a stronger methane adsorption capacity to move closer to the ventilation opening, thereby improving the methane adsorption effect and avoiding waste of activated carbon particles.
