Wood Activated Carbon is a black powder, granular or pellet or amorphous with porous carbon. The main component is carbon, which also contains small amounts of oxygen, hydrogen, sulfur, nitrogen, and chlorine. It is mainly made of wood, fruit shells, coal and other high-temperature activation. Carbon is the most stable element in nature. Activated Carbon also has this feature. Activated carbon pore structure is advanced, with a large surface area (500 ~ 1000 m2/g), even higher, has a strong physical adsorption properties, can adsorb gas, liquid or colloidal solids; for gases, liquids, adsorbed substances The quality can be close to the quality of the activated carbon itself. Its adsorption is selective, non-polar substances are more easily adsorbed than polar substances. In the same series of substances, substances with higher boiling points are more easily adsorbed, and the pressure is higher, the temperature is lower, the concentration is greater, and the amount of adsorption is greater. Conversely, decompression and warming are favorable for desorption of gases.

Second, filter bag cleaning wind pressure to maintain more than 0.5MPa, require oil and water separation, air bag should be timely release of water. Always inspect the interior of the baghouse to open and close the air duct, and control the sweeping air. Check the degree of clogging of the filter bag and find that it is slightly clogged. Take it out in time to dry it and beat it. Ensure that the ventilation capacity is normal, and avoid the blockage and continue to operate to form a vicious cycle.
Third, carry out frequent inspections on the air leakage of exhaust gas treatment systems, implement full-scale plugging, and perform necessary external insulation on the exhaust gas exhaust system.
Fourth, the cold mill season cold boot, try to avoid excessive temperature during the material moisture into the mill; pay attention to control the feed rate; circle flow mill can increase the amount of powder back to increase the wind temperature inside the mill. Before stopping the grinding, extend the stop time as much as possible, and stop the mixture of high moisture content as soon as possible. After stopping the grinding, properly extend the exhaust time in the mill and do a good job of transposing the grinding body.
5. The loading amount of the grinding body should be appropriate to avoid affecting the ventilation area of ​​the hollow shaft. The clogging of quilting should be promptly cleaned. It is forbidden to mix materials such as iron slag into the grind to avoid clogging. To maintain the ventilation capacity inside the mill is stable at a good level; - Once there is a change, the exhaust fan can still be used to adjust the amount of ventilation to maintain the best ventilation, such as the T factory ordered a difficult to block the quilting of the compartment board and the discharge plate , Stable ventilation area.
Five kinds of maintenance methods for bag filter
First, equipped with mill water spray mill, to ensure good atomization. Stop the water a quarter of an hour before stopping grinding. Avoiding the evaporating of moisture evaporates the filter bag.
