How to do the explosion-proof measures of environmental protection spray booth?
The centrifugal fan with high performance and blade safety factor should meet the requirements of the industry standard. The external fan of the motor should be used, and the motor should be placed outside the air duct, which can effectively avoid the potential electrical safety hazards and prevent the accumulation of paint mist on the blade.
A water spray mist eliminator is added to the exhaust system. A water washing device is added to the device before the exhaust. The multi-stage water spray is used to further collect the fine particles passing through the dry filter material. This method is similar to the paint mist purification method of the wet spray booth, which can avoid the accumulation of paint in the fan and air duct, and reduce the probability of explosion and fire.
Regularly renew the diesel filter element (every 8-12 months), clean the filter screen of high-pressure oil pump once every 6 months, and clean the filter screen of high-pressure nozzle once a year.
The above is about the introduction of spray painting and baking room, and the brand of diesel oil used must be 5 degrees higher than the local extremely low temperature at night. It is not allowed to use recycled oil, water or other impurities of diesel oil.
The environmental protection paint baking room can not use the damaged cloth bag to work, otherwise it will accelerate the scrapping of the dust collector. When some cloth bags are damaged in a small area, the holes can be filled with old cloth bags or new filter cloth of the same material. The hole filling method is to use silicone rubber mixture for bonding, as long as the temperature and chemical properties of the adhesive are suitable for the process conditions.
The environment-friendly paint baking room is gradually worn. The main causes of wear are the grinding force of dust, the deterioration of filter material and the corrosion of chemical substances caused by high temperature. When the grinding force of dust is very strong, the bottom of the bag is seriously worn, and the increase of system capacity causes the increase of filtration speed, which can also accelerate the wear.
When most of the bags are damaged, they should be replaced completely (when the fine dust accumulated in the filter layer reduces the air permeability after long-term operation of the filter material and affects the air volume of the system, they should be replaced completely even though they are not damaged). The replacement of the bags should be carried out when the dust collector stops working. At this time, the dust removal controller should be closed and the inlet door at the top should be opened to remove the bags, When disassembling, take out the bag cage first, then pinch the spring ring at the upper opening of the cloth bag into a concave shape, pull out the cloth bag upward, and clean the dust on the hole of the pattern plate before installing a new cloth bag.
