Brief introduction of technological process:
Tyre oil is delivered into the pretreatment tank through oil pump, then adding flocculant and other additives for removing water, impurity and colloid. Compressed air injected by air compressor for oil stirring. Stirring intensity controlled by air compressor valve, Meanwhile, start pretreatment heating cycle pump, deliver tyre oil from reactor tank to waste heat energy saving processor for exchange heating, gradually heating oil until 40-80℃. Heating while stirring for around 40-60 minutes, then static precipitation around 3-4 hours for water and slag removing. Finally the waste water and slag will be delivered to sewage treatment plant for special treatment, and treated water will be recycled for cooling.Treated slag will be dry out for the material of ash brick. Add liquid pyrolysis catalyst to the treated oil, get them stirred and heated for 30 minutes, until the temperature to be 40-80℃. Deliver tyre oil into 1# horizontal rotary heating furnace via oil pump, meanwhile, start-up heating system like oil burners, natural gas burners etc. for pyrolysis distillation, when temperature of each fraction gradually reach 120 - 360 ℃, each fraction of gas go to high efficiency atmospheric fractionating tower (CT-101) for fractionation. Top oil gas go to reflux tank, liquid back to tower while gas run from combustible gas pipeline. Tower have two exits from side: top one for light diesel oil, lower one for diesel. Respectively enter condenser --cooling tank -- oil-water separator -- mid oil tank (light diesel ,diesel) -- refining filter for filtering through pump-- end oil tank (light diesel, diesel). Via high temperature oil pump, bottom oil of atmospheric fractionating tower (CT-101) can reflux to 1# horizontal rotary heating furnace anytime, go on heating for pyrolysis distillation. according to oil pyrolysis distillation process, irregularly check oil quality and estimate yield , spot check the bottom oil. Regularly deliver the residue oil to condenser and cooling pool via high temperature reside oil pump,finally go residue oil tank. Vacuum negative pressure technology is adopted during process. After condenser system, top of middle oil tank have non-condensable gas outlet, then the gas enter vacuum negative pressure system. Via vacuum pump, extract the non-condensable combustible gas from middle tank to vacuum system, then go to exhaust pipe.Waste gas recycling: When non-condensable combustible gas enter exhaust pipe, treated by vacuum tank which is for secondary filtration. Treated exhaust gas together with the non-condensable combustible gas from reflux tank of top tower, enter non-condensable combustible gas pipe network. In case of fire, they should run through retardant storage cabinet, finally go to furnace for burning, act as fuel. By this way, not only save energy and economical, but also avoid pollution.Smoke and dust removal system also be adopted during production. Once start working, light up heating furnace, start-up draft fan, the smoke extracted from reactor first treated by waste heat energy processors, then handled by Tower spray smoke desulfurization secondary processor , finally go to draft fans, emissions until they are white and standard.
