Subsequently, the purified air flows to the air outlet pipe 103 and passes through the activated carbon filter and particulate filter assembly to further remove fine particulate matter and harmful gases. At this time, the air compressor 8 starts and delivers the treated air into the laboratory at an appropriate pressure. When the ash box needs to be cleaned, the operator controls the rotary valve 7 to ensure that dust does not flow back into the dust collector 1. The moment the rotary valve 7 is opened, the spray assembly at the bottom starts working, and the spray head 9 sprays water mist into the ash box, creating a humid environment and effectively suppressing dust from flying. Throughout the entire process, maintenance personnel can easily clean dust without polluting the laboratory environment, thereby ensuring the laboratory's air quality and the safety of operators. This integrated design and operating process ensures the efficiency, safety, and cleanliness of the laboratory.
