Dust absorption tube of wet-type feeding device of powder active carbon (PAC)

Abstract

The invention discloses a dust absorption tube of wet-type feeding device of powder active carbon (PAC). The dust absorption tube is a hollow and airtight cylinder. The dust generated by the wet-type feeding device of the PAC enters into an air inlet on the dust absorption tube through pipes. An air pipe is arranged inside the dust absorption tube. One end of the air pipe is communicated with theair inlet and the other end of the air pipe is arranged at the bottom of the dust absorption tube. A plurality of spray nozzles which are arranged on the dust absorption tube are communicated with a first water inlet with a first inlet valve, and the bottom of the dust absorption tube is connected to an escape pipe with an emptying valve. The top of the dust absorption tube is provided with an exhaust port for discharging clean gases. The dust absorption tube absorbs the PAC in the gases in a mixing mode of spray and steam, thus the dust generated by automatic, manually operated and manual-automatic wet type feeding device of the PAC can be recycled and reused, thereby improving the environment around devices and saving the PAC.

Description

technical field [0001] The invention relates to an improved dust collection equipment of a wet-type dosing device for powdered activated carbon, in particular to an auxiliary device for recovering and utilizing powdered activated carbon dust. 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 and odor of raw water, reduce turbidity, 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 ...

AI Technical Summary

Problems solved by technology

In the powdered activated carbon automatic wet dosing equipment, several mixing cylinders are connected in series, powdered activated carbon and water are automatically added to the mixing cylinder, the mixing cylinder is closed, in order to keep the pressure in the mixing cylinder constant, to ensure that the powdered activated carbon and water can be added smoothly The mixing cylinder and the mixed liquid can be delivered smoothly, and the upper end of the mixing cylinder needs to be provided with a breathing port that communicates with the outside atmosphere, but 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 that the dust This not only caused serious dust pollution to the surrounding environment, but also caused a waste of powdered activated carbon, so some operators installed a bag filter at the breathing port to reduce dust pollution, but the effect was not good and the Increased equipment complexity, input costs and operating costs

In the powder activated carbon manual wet dosing equipment, several mixing cylinders can be independent of each other in parallel and run alternately, or can be connected through connecting pipes to form a series type. The upper end of each mixing cylinder is equipped with a manual feeding port. The artificial feeding port is manually added into the mixing drum, but the powdered activated carbon will also generate dust during the process of adding the mixing drum, and the dust is easy to escape from the mixing drum through the manual feeding port, which not only causes serious dust pollution to the surrounding environment, but also causes Reduced waste of powdered activated carbon
