Environmental impact assessment of dry adsorption device for organic waste gas treatment in Weifang rubber plant
Product overview
Activated carbon adsorption device is mainly applied in organic waste gas processing, paint mist, composed of two parts, including the adsorber perforated plate, filter cotton mist layer and active carbon adsorption layer etc.. The utility model is made of high quality PP, and the utility model adopts the movable structure to eliminate the paint mist. The utility model has the advantages of good corrosion resistance performance, good power saving, convenient operation and maintenance, etc. the utility model is suitable for the treatment of organic waste gas in furniture, wood industry, leather making, hardware and building materials industry.
Working principle
Under the action of centrifugal fan, the organic waste gas in the workshop enters the activated carbon adsorption device through the air pipe. First, it enters into the mist sprayer, and then filters out the tiny particles in the waste gas. After pretreatment, the organic waste gas enters the activated carbon adsorption layer. Activated carbon (adsorbent) due to the porous structure with a large specific surface area (generally 700 - 1500m2/g) has excellent adsorption capacity, pore size distribution is generally less than 50A. When the organic gas (adsorbate) is in contact with the activated carbon, it has a strong interaction force with the organic gas - Fan Dehua force, the organic gas is trapped and adsorbed by the active carbon layer, so as to achieve the purpose of purification.
Operation and use
1, inspection before operation: (1) check whether the installed and activated carbon filter; (2) check the activity of activated carbon adsorption equipment is in the door (mouth) fastening state; (3) check whether the normal motor (mainly centrifugal fan); (4) check the rack of the connected parts and bolts no loosening, should be adjusted to ban solid;
2, operation process: (1) on the power switch, the power indicator light; (2) the fan button to the right turn, equipment indicator light; (3) equipment indicator light, fan running; (4) the wind machine starts, at normal speed, should be in the process of operation often check the bearing temperature is normal. Bearing alone shall not exceed the ambient temperature of 40 degrees C; (5) when the fan is running, pay attention to the pressure gauge and the current value of the box, if there is abnormal need to be overhauled.
Operational matters needing attention
1, only the fan device is fully operational only under normal conditions; 2, in normal operation, the activity of activated carbon adsorption equipment must be fastened; 3, the wind machine equipment starting after the overhaul, it must pay attention to the position of the fan is normal. 4, regular cleaning of paint mist particles layer, prevent resistance increases, reduce the treatment effect. The paint mist layer is a movable structure, and the movable door can be opened and cleaned. Cleaning cycle can be determined according to the actual situation, painting exhaust gas generally two days. 5, regular replacement of activated carbon, saturated adsorption efficiency of activated carbon reduction, should be regularly discharged from the bottom of the material, re install the new activated carbon. Replacement cycle should be determined according to the actual situation, paint exhaust is generally three months. 6, regularly check whether the normal circulation of the fan, to prevent the fan bearing temperature is too high and loss. 7, in order to ensure the safety of the people, in the activated carbon adsorption into the set of operations must be in the parking. 8, in the process of operation of the equipment, such as abnormal circumstances should be checked immediately, if a small fault should promptly identify the cause and try to eliminate, found a large failure should immediately stop maintenance
