Abstract
The invention discloses a dust absorbing device of a mixing barrel in an automatic wet powdery activated carbon adding equipment. The dust absorbing device of the mixing barrel in the automatic wet powdery activated carbon adding equipment sucks dust into a respiratory tube from a respiratory port along with air through the exhalation action of the respiratory port, then the dust enters an absorbing tank from the respiratory tube and is absorbed by water in the absorbing tank, clean air is discharged out of a respiratory tank, the dust absorbed by the water and the water form a mixed solution of powdery activated carbon and the water, and when the concentration of the powdery activated carbon in the mixed solution reaches the addition requirement, an air release valve can be opened, and the mixed solution is discharged out of the air release valve and can be added to a process addition point to be added with the activated carbon. When reserving the respiratory function of the respiratory port, the device solves the problem of dust pollution generated during feeding by the mixing barrel so that the collected dust is recycled, and the powdery activated carbon is saved; and the dust absorbing device has the advantages of low investment and running cost, reliable running as well as simple and convenient operation.
