Set up dust removal drying mechanism, can effectually remove dust and dry VOCS waste gas, a large amount of dusts and moisture that contain in the waste gas can reduce the life of active carbon, so dust removal drying mechanism further improves the purification efficiency of VOCS waste gas through the life who improves active carbon.
After VOCS waste gas is dried by the drying box 10, the waste gas enters the purifying box 14, the motor 17 is turned on, because the output end of the motor 17 is connected with the rotary cake 19, the motor 17 can drive the rotary cake 19 to rotate, the rotary cake 19 is provided with a heart-shaped groove, and two sides of the heart-shaped groove are provided with openings, when the rotary cake 19 rotates, two adjacent sliding columns 21 can alternately enter the heart-shaped groove, because the sliding columns 21 are fixed on the rotary frame 20, when the sliding columns 21 alternately slide in the heart-shaped groove, the rotary frame 20 can be driven to intermittently rotate, and because the rotary frame 20 and the fixed frame 22 are both fixed on the main shaft 18, when the rotary frame 20 rotates, the fixed frame 22 can also follow to rotate. The fixed frame 22 is connected with an electromagnet 23, the electromagnet 23 can rotate on the fixed frame 22, the power supply of the electromagnet 23 and the motor 17 are the same power supply, the electromagnet 23 can also generate magnetic force after the motor 17 is started, and the first activated carbon 24 is fixed with an iron plate 25, so that the electromagnet 23 can adsorb the first activated carbon 24 when generating magnetic force. The rotation of mount 22 can drive first active carbon 24 and rotate in purifying box 14, because electro-magnet 23 can rotate on mount 22, the reaction layer passageway through the first active carbon 24 of action of gravity remains the horizontal direction throughout, can guarantee that each inside reaction channel of first active carbon 24 carries out even absorption to VOCS waste gas from this. After the exhaust gas fully reacts with the first activated carbon 24, the exhaust gas after the reaction treatment is guided by the third suction fan 29 to enter the exhaust pipe 32, and the second activated carbon 31 is arranged in the exhaust pipe 32, so that the exhaust gas can be further purified. Set up intermittent type slewing mechanism, can guarantee that VOCS waste gas is even through every first active carbon 24, make inside each part of first active carbon 24 fully carry out adsorption work to waste gas, can improve the purification efficiency of waste gas, can prolong the life of active carbon again, practiced thrift the cost.
After VOCS waste gas is sufficiently adsorbed and purified by the first activated carbon 24 and the second activated carbon 31, the treated gas is discharged by the exhaust pipe 32, harmful substances contained in the VOCS waste gas are adsorbed in the first activated carbon 24 and the second activated carbon 31, the valve 6 at the bottom of the dust removal box 1 is opened, the sewage in the dust removal box 1 can be discharged by the valve 6, the filter screen 5 can filter the sewage, when the water level in the dust removal box 1 is reduced, the pressure applied to the pressure sensor 9 is reduced, the first suction fan 11, the second suction fan 13 and the third suction fan 29 stop working, the sealing valve 15 is opened, the power supply of the motor 17 and the electromagnet 23 is closed, the fixing frame 22 stops rotating, the first activated carbon 24 falls off from the electromagnet 23, so that the first activated carbon 24 can be discharged from the interior of the purifier through the sealing valve 15, and the first activated carbon 24 at two sides of the sealing valve 15 fall on the sliding plate 26 and then is discharged by the sealing valve 15, when the first activated charcoal 24 slides on the upper surface of the slide plate 26, the telescopic switch 27 can be pressed and closed, and the telescopic switch 27 is connected with the telescopic column 30, so that when the telescopic switch 27 is closed, the circuit is connected to extend the telescopic column 30, and the second activated charcoal 31 is pushed out of the purifier. When both the first activated charcoal 24 and the second activated charcoal 31 are discharged from the interior of the purifier, the telescopic switch 27 returns to the off state, and the electric circuit breaking telescopic column 30 shortens to the initial state. Set up automatic disassembly body to in carrying out automatic disassembly to the active carbon and collecting, improve the handling efficiency of active carbon, avoid VOCS waste gas to cause the injury to the user.
