Utilize waste plastic to produce the equipment of gasoline, diesel, include cracking still, condenser, the cracked oil storage tank, still kettle, the gasoline, diesel storage tank, it is characterized in that still base under the described cracking still executes heat in last convex dish lower cover, whipping appts places the center of still, agitating vane is corresponding with end socket, the cracking and catalyzing device is equipped with on kettle top, this catalyst converter links to each other with condenser, condensator outlet is installed on the cracked oil storage tank and even is contained in the still kettle through volume pump, this still lower cover all adopts convex, the top of still is provided with catalyst converter, be installed on the condenser, the outlet of condenser is connected on the gasoline, diesel storage tank.
Pay-off and tensimeter also are housed on the described cracking still, safety valve, be equipped with except that cinder notch the bottom.
Advantage of the present invention and positively effect are:
One, raw material is entirely waste plastic, and the thermo-efficiency height is all carried out in fusing and cracking in cracking still.Its two, to be hydrocarbon gas carry out through the furnace roof outlet time for catalysis, cracking reaction, sufficient reacting, product performance are good, and are stable.And the ratio of catalyzer and reactant is 0.1%.Its three, technical process is simple, operability and high safety.Its four, in the production process owing to be that cycling use of water and cracking deslagging thing are that industrial goods raw material and body of heater are reasonable in design with smoke discharging structure, so, no waste water,waste gas and industrial residue pollution.
Description of drawings is as follows:
Accompanying drawing of the present invention is the structural representation of technical process and equipment configuration.
Embodiment:
Below in conjunction with accompanying drawing, enumerate embodiment the present invention be further described:
At first waste plastic is selected classification.Remove impurity, clean dry, standby.
Get the raw materials ready after will handling and send in the cracking still (4) by automatic feeding (5) continuous and quantitative.By (1) at the bottom of the cracking still calorify begin after end socket (2) makes temperature in the kettle be elevated to 70 ℃ the fusing.Connect whipping appts (3) work this moment, make its waste plastic fusing fast evenly, thereby form the liquid alkane mixture.Still kettle base (9) is equipped with thermometer (17) and tensimeter (19), safety valve (20) on end socket (10) heating kettle.Temperature in the kettle is controlled at 70-320 ℃, and the liquid carbon hydrogen mixture generates hydrocarbon gas gradually, by the hydrocarbon gas of cracking process generation, through cracking catalysis device (6) cracking reaction, the 1kg cracking catalyst is housed in the cracker, but continuous effective processing 1000kg cracked oil, and its catalyzer composition is a pure aluminium silicate.Through condenser (7) condensation, generate cracked oil, flow into the cracked oil storage tank.Every still was produced 8 hours, and blowing out when furnace temperature is reduced to below 35 ℃, is opened except that cinder notch (18) connection whipping appts (3) after about 1.5 hours, but just self-skimming.Under the processing condition of works better (temperature in the kettle 70-320 ℃, catalyzer is in processing cracked oil 1000kg, recirculated water supplies water normal) per hour reinforced 100kg, and it is 690kg that per tour was produced cracked oil in 8 hours, then oil yield is 690/800=86.2%.Cracked oil is driven in the still kettle (11) from cracked oil storage tank (8) by volume pump (16).The still kettle temperature is controlled at 50-320 ℃, makes cracked oil generate hydrocarbon gas, and this hydrocarbon gas just can generate gasoline, diesel through catalyst converter (12) time.Hydrocarbon gas in the still kettle is when ejecting mouthful through still, and when temperature in the kettle was controlled at 50-190 ℃, (composition was a rare earth, carclazyte and ferric oxide Fe with catalyst B Z in the catalyst converter (12)
2O
3) react, after condenser (13) condensation, enter in the gasoline tank (15), just produce and meet GB/T5487 90#-95# white gasoline.The distillation temperature in the kettle is when being controlled at 190-320 ℃, hydrocarbon gas and the catalyst B Y in the catalyst converter (12) (composition is a kaolin) reaction that the still of flowing through ejects mouthful, after with fixed attention generation meet GB/T252-87-20-45 ℃ solar oil, enter in the diesel oil tank (14).
Above gasoline rate alkane value and diesel oil zero pour can obtain required label according to user's needs by adjusting catalyst proportion in above-mentioned scope.
