Active carbon dust-free grinding device and method

Abstract

The invention relates to an active carbon dust-free grinding device and a method. A feeding screw conveyer of the device is installed in a feed port of a raymond mill. The discharge port of the raymond mill is connected sequentially to a cyclone separator, a pulsed bag-type dust collector and a centrifugal fan through negative pressure pipelines. Bottom discharge ports of the cyclone separator and the pulsed bag-type dust collector are both provided with a rotary valve. The bottom of the cyclone separator is provided with a finished-product bunker. The rotary valves are connected to the finished-product bunker. The rotary valve of the pulsed bag-type dust collector is connected to a finished-product screw conveyer connected to the finished-product bunker. An air outlet of the centrifugal fan is connected to a spray tower through a dust discharging pipeline. The spray tower is connected to a recovery tank. According to the active carbon dust-free grinding device and the method, a negative grinding device and an exhaust gas treatment system are adopted; the structure is simple and reasonable; the production method can be implemented easily; dust pollution in a grinding process in largely reduced, thus providing a good working environment for workers; and the active carbon in the dust can be collected and utilized, thus avoiding waste effectively.

Description

Technical field [0001] The invention relates to the technical field of activated carbon production, in particular to an activated carbon dust-free grinding device and method. Background technique [0002] Activated carbon is powdery or granular amorphous carbon. Because of the irregular arrangement of microcrystalline carbon, there are fine pores between cross-connections, which will produce carbon structure defects when activated, so it has highly developed pores Structure and huge specific surface area, strong adsorption capacity, good chemical stability, high mechanical strength, easy to regenerate after use failure. Activated carbon processed by milling machine is widely used in chemical industry, food processing, medical and health, agriculture, national defense and other fields. [0003] Commonly used mills for grinding activated carbon include ball mills and Raymond mills. The shaped ball mill is continuous feeding and discharging. Generally, the feeding amount is adjusted...

Problems solved by technology

However, during the grinding process of the ray mill, due to its light specific gravity, a large amount of dust will be emitted during the production process, which seriously affects the health of the production workers and the environmental quality of the surrounding areas.
