[0003] During actual use, the refined cotton transported by air flow discharges waste gas and dust through the cyclone separator, the fiber dust is intercepted by the spray water mist in the return air cabinet, and the purified waste gas is discharged into the air. Due to insufficient spray interception space and the lack of a defoaming device, the discharged waste gas carries a large amount of mist water. At the same time, the purification efficiency is low, and the particulate matter emission index fluctuates greatly, which affects work efficiency and makes it inconvenient to achieve efficient wet purification.

[0004] Therefore, in order to solve the above-mentioned problem of inconvenience in achieving efficient wet purification, a fiber dust wet purification device can be designed. When the dust purification device is in use and working, the smoke containing fiber dust is first sucked into the washing drum through the smoke inlet component. At the same time, the circulation component extracts the purified circulating liquid from the circulating liquid storage tank, and sprays it evenly in the washing drum through the spray component, so that it fully contacts the smoke and achieves preliminary purification. The starting active motor can drive the active gear to adjust and rotate through the active shaft, and the active gear can drive the two groups of spray components to adjust and rotate through two groups of driven gears, so that the two groups of spray components can spray and clean each other to enhance the washing effect. The smoke passes through the vortex flow demister and the baffle demister to further remove fine droplets and dust, and finally the purified gas is discharged. The sewage and impurities generated during the washing process are filtered and discharged through the sewage discharge component, and recycled after treatment. The entire device achieves efficient wet purification of fiber dust through the coordinated work of various components. Summary of the invention
