Gas and oil and electricity are generated from waste, air emissions are below government laid standards.
The pyrolytic oil and gas mixture (about 500˚C) from rotating bed will be continuously sprayed by 75˚C circulating pyrolytic water to 85˚C, and enter a wet de-dusting column where it will be sprayed by chilling circulation water pumped by a pump to remove the dust in pyrolytic gas. Finally, the mixture will enter two horizontal tube primary coolers operated in parallel (1W + 1S). The primary cooler will use the cooling water of two sections (32˚C circulating water and 16˚C cooling water) to cool pyrolytic gas to about 21-22˚C. The pyrolytic gas discharged at the lower part of primary cooler will enter two electric tar catchers operated simultaneously in parallel manner.
The high temperature pyrolytic oil and gas mixture will enter a separation unit where it will be continuously sprayed by 75˚C circulating pyrolytic water to 85˚C, and enter a wet dust-removing column where it will be sprayed by chilling circulation water to remove its dust, and then enter the horizontal pipe primary cooler. The primary cooler will use 32˚C circulating water and16˚C cooling water to cool the dust-removed pyrolytic gas to around 21-22˚C to further condensate its water, and the residual gas will enter electric tar catcher.
During the operation of electric tar catcher, a high voltage electric field is formed inside the catcher which causes the ionization of pyrolytic oil and gas that pass through the catcher. After charging, the pyrolytic oil particles will gather toward the precipitating electrode, and will be discharged through the bottom outlet. Following the removal of pyrolytic oil in the pyrolytic gas, the gas will be sent by Roots blower to dry DE Sox tower. The pyrolytic gas will enter the four-basket-type dry DE Sox tower installed with desulfurizer from the lower part of tower, and be discharged from the upper part of the tower so that the tower newly replaced with desulfurizer is still at the end to achieve best desulphurization effect.
The separated pyrolytic oil and circulating pyrolysis water will enter a mechanical oil-water separation tank. The light oil separated from the tank will flow into an intermediate tank, while the heavy oil at the bottom of separation tank will be pumped by a pump to the intermediate tank, finally, the pyrolytic oil in intermediate tank will be sent by a transfer pump to boiler.
