It is clear that the power saving system 10 for organic waste gas treatment is a system for organic waste gas treatment facing the whole plant, and is different according to the area where the plant is placed or the equipment is placed. The organic waste gas generated by each factory workshop or equipment is different, the production equipment uses different seasons and different production equipment attendance rates, the gas collecting branch pipes 220 can be arranged in different workshops, and the branch pipe valves 230 are arranged between the gas collecting branch pipes 220 and the gas collecting main pipe 210, so that the suction force of the gas collecting branch pipes 220 can be controlled by controlling the branch pipe valves 230. When the factory workshop or equipment area corresponding to the gas collecting branch pipe 220 is in the non-starting state, the branch pipe valve 230 is in the closed state; when the plant or equipment area is in a partially powered on state, the suction of the gas collecting hoods 110 in the plant is controlled by the gas collecting valve 120 and the branch valve 230.
The fan 410 provides total suction, collects the waste gas generated by the factory through the gas collecting hood 110, and treats the waste gas through the UV lamp tube 310, the plasma generator 320 and the combustion chamber 340 in the waste gas treatment device 300, so as to eliminate the organic waste gas and achieve the emission standard.
