Dust absorbing device of mixing barrel in automatic wet powdery activated carbon adding equipment

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 solutionof 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.

Description

technical field [0001] The invention relates to a dust absorbing device, which is used for absorbing the dust produced by a mixing cylinder in an automatic wet feeding equipment for powder activated carbon when feeding materials. Background technique [0002] The pollution of drinking water sources in my country is becoming more and more serious, and there are many types of organic substances in water sources. In the process of water treatment, activated carbon is usually added to adsorb and remove organic substances and other impurities in raw water. Due to the large specific surface area of ​​powdered activated carbon, it has strong adsorption, which can effectively remove the color, turbidity and peculiar smell of raw water, and effectively reduce the pollutant content in raw water. [0003] The dosing method of powdered activated carbon usually adopts the wet dosing method, that is, after mixing the powdered activated carbon with water, the mixture of powdered activated ...

AI Technical Summary

Problems solved by technology

In the powdered activated carbon automatic wet dosing equipment, several mixing cylinders are connected in series, and the powdered activated carbon and water are automatically added into the mixing cylinder. It can be added into the mixing cylinder and the mixed liquid can be given out smoothly. The upper end of the mixing cylinder needs to open a breathing port that communicates with the outside atmosphere. However, powdered activated carbon will generate dust during the process of adding the mixing cylinder. It is precisely because of the breathing port at the upper end of the mixing cylinder. It is easy for the dust to escape from the mixing cylinder, causing serious dust pollution to the surrounding environment, which not only endangers the health of the operators, but also causes waste of powdered activated carbon

Therefore, some operators installed a bag filter at the breathing port to reduce dust pollution, but the effect was not good and it also increased the complexity of the equipment, input costs and operating costs.
