Introduction
Main Furnace Description: Because the common oil sludge, oilfield waste, tar sludge (mud) in the composition is not uniform, containing part of the coke, asphaltene and a certain amount of water, so the heating and treatment process is very easy to produce coking and sticking to the wall, so this program selects the rotary furnace.The biggest feature of the rotary furnace pyrolysis equipment is that it has a good mixing effect on the material, which can get a more uniform pyrolysis product. Adopting inter-wall heating method, the material does not directly contact with oxygen and oxidization reaction does not occur, so it will not produce dioxin. There are various choices of heating fuels for this system, such as coal, oil, natural gas, fly ash, biomass, lava rock, hot air, etc.
Description of slag discharging system: The content of solidified materials in hazardous wastes such as oily sludge, oilfield waste, tar slag (mud) is high, and the residue after pyrolysis carbonization is completed requires a long time to cool down, which will affect the production efficiency. The pyrolysis treatment equipment designed by Ruilong Company adopts closed high-temperature slag discharge device, which can transport the residue out of the furnace at a high temperature of about 180℃, and transfer it to the outside of the furnace to cool down through the multi-stage water-cooled spiral slag discharge machine.
Anti-coking wall clearing device: Oil-containing sludge, oilfield waste, tar slag (mud) and other hazardous wastes, containing asphalt, paraffin and gum, etc., in the heating process, it is easy to form a coking layer in the inner wall of the furnace, which affects the heating speed of the material, the reaction, the service life of the equipment and the productivity, and in serious cases, it will also make the outlet of the furnace chamber blocked and forced to stop the furnace; and the material is easy to clumping clumps, which affects the slagging and the production efficiency. Ruilong company exclusive R & D and design of anti-coking wall clearing device, fixed in the pyrolysis furnace, can realize real-time wall clearing, do not give the material coking enough time to stay.

Description of integrated water tank cooling system: The pyrolysis system adopts the integrated water tank cooling system, in which the horizontal cooling pipe in the water tank will be inclined at a certain angle (10-20°) so that the oil will naturally flow to the lower part. The inlet pipe is φ325, with an inclination angle of ~20°; the middle pipe is φ219, with an inclination angle of ~15°; the outlet pipe is φ108, with an inclination angle of ~10°, and the oil will converge at the blind plate protruding from the two ends, and then flow into different pipes. When the oil is just precipitated, the flow is larger and there are more impurities, the thicker cooling pipe can make the impurities precipitate at the bottom of the pipe, which has less influence on the oil and is not easy to be clogged; the design of one-piece water tank is convenient for transportation and installation. The two ends of the cooling water tank are sealed by blind plates and connected by screws, when cleaning and maintenance, only need to open the blind plates at both ends, and use the pipe slightly longer than the cooling pipe with the stopper smaller than the inner diameter of the pipe to dredge and clean up, easy and convenient to operate.
