By feeder 1 charging, through 2 feedings of feeding spiro rod thruster, first section is heated to 280 ℃, and this moment, polyvinyl chloride began to separate out HCL, and second section is heated to 320 ℃, and this moment, HCL analysed substantially.HCL a large amount of in the cavity suck bubbling chamber 17 and water dissolution by vacuum pump, form hydrochloric acid, are collected by hydrochloric acid discharge outlet 18.The liquid plastics of this moment enters cracker 6 (its improved action is not discharge opeing of deslagging, evenly stirs oil gas is generated fast) to be continued to heat up.The liquid Flow Injection Chemiluminescence Method, the automatic sludge discharge continuous production, waste residue is discharged through slag-drip opening 22 by mill, and the waste residue carbon atoms can be made breeze block for burning, and its combustion value is equivalent to firewood.500 ℃ of high temperature make the oil gas molecule (mainly being paraffinic hydrocarbon) of a large amount of two key forms enter catalyzing tank 4, and (its improved action is to prevent that slack wax and carbon distribution from stopping up, by blower fan 19 with warm air homogeneous combustion from the multitube space, cut down the consumption of energy), under the effect of catalyzer, be cut into singly-bound mixed oil and gas molecule.Enter intermediate condenser 7 by oil gas vent 5, non-condensable gas and mixing oil are separated.Non-condensable gas becomes liquefied gas after taking in first gas-holder 13 by compressor 12, and it is personal to enter burner air inlet 21 by pipeline, and unnecessary liquefied gas enters first strainer 14 by liquefied gas outlet 27, and open purging valve 15 and send into second gas-holder 16, but supply the market.And mixing oil enters gasoline rectifying jar 8, at 180-200 ℃ gasoline distillation is come out, by fuel dispensing outlet 9 through second strainer 31 to gasoline tank 32.Remaining mixing oil continues to enter back road diesel oil rectifying jar 10 and at 320-340 ℃ diesel oil is distilled, by diesel oil outlet 11 after the 3rd strainer 33 filters to diesel oil tank 34.A spot of heavy oil is discharged the oil that acts as a fuel by putting heavy oil mouth 25.Whole technological process temperature, pressure are by monitored meter, and PLC (Programmable Logic Controller, programmable logic controller) controls, and temperature error is at ± 5 ℃, and pressure produces voltage by transmitter and handles to PLC.Pressure-controlling within the specific limits, non-condensable gas is pressed into gas-holder automatically by two stage compressor, control compressor rotary speed according to the pressure size by variable-frequency motor, whole technological process is coordinated very much, is done the circulation cooling of complete machine by water pump 26 responsible entrance of cooling water 28 and cooling water outlet 29.The waste plastics refining unit of successive type of the present invention is equipped with power supply overflow and overheat protector and safety valve 3 etc., and every security measures is complete.The good reliability that this device uses, each parts of whole device are installed on the step-like integrated frame, and the front and back operation is connected by pipeline, and the action of each circuit unit realizes full-automatic internal recycle control by electric control box by parameter.Whole technological process is discharged non-secondary pollution a spot of carbonic acid gas by vapor pipe 30 in burning.Discharge by first dewatering outlet 23 and second dewatering outlet 24 behind a spot of water vapor condensation.
Negative pressure cavity dechlorination device is made up of feeding spiro rod thruster 2, chlorine purifier 20, bubbling chamber 17, hydrochloric acid discharge outlet 18 and vacuum pump 36, utilizes the volume differences of plastics raw material and melt, has made a cavity and form negative pressure between the heating zone of front and back.The first heating zone temperature is at 280 ℃, and HCL begins to separate out (vaporization), and the second heating zone temperature is controlled at 320 ℃, and HCL has analysed substantially, and cavity is connected with vacuum pump HCL suction bubbling chamber (utilizing the water miscible characteristics of HCL) and water dissolution formation hydrochloric acid.Whole process mainly is to eliminate secondary pollution, improves the quality of oil product, reduces the acid number degree of oil product, obtains byproduct hydrochloric acid simultaneously.
Inverter type stirs the automatic sludge discharge reactor and is made up of cracker 6, blower fan 19, burner air inlet 21 and slag-drip opening 22, inverter type stirs the automatic sludge discharge reactor liquid plastics that is flowed into by former process is mixed, mix for two the inclined rib is housed on the loom, form continuous circular arc in the running, play the effect of scraping the end not discharge opeing of deslagging, but the liquid Flow Injection Chemiluminescence Method, the plastics oil gas of generation rises up into vertical catalyzing tank naturally by laddertron.Whole process deslagging takes control automatically to combine with artificial the adjusting, and different plastics produce the waste residue that does not wait, and to reach best deslagging effect, lays the foundation for realizing serialization production.
The present invention has solved congee sample bubble slurry in the mixed oil and gas that reactor produces technically and has given birth to and rise the phenomenon of blocking catalyzing tank inlet and catalyzer, prevents effectively in the scission reaction process because carbon distribution causes the oil gas blocked situation that enters the mouth.Multitube refluence formula catalyzing tank is made up of catalyzing tank 4, oil gas vent 5, vapor pipe 30 and safety mouth 35, the purpose of multitube is to circulate in the multitube gap by warm air by blower fan, make warm air evenly smooth, improve heat effect (catalyzing tank does not need direct heating), use the catalyzing tank of this device both can strengthen the katalysis of catalyzer, can prolong the work-ing life of catalyzer again.
In sum, " waste plastic thing " (as vest bag, food bag, woven bag, disposable lunch box and foam materials etc.) need not clean through after the pulverizer fragmentation, send into the feeding spiro rod thruster by feeder and under the effect of screw rod, enter heating zone, decomposite HCL earlier and carry out dechlorination, enter reactor and catalyzing tank then, under the effect of technological temperature and catalyzer, generate CH after material melting and cracking, the gasification
4, C
2H
8Deng gaseous olefin.Wherein the hydrogen chloride gas that produces during the chlorine-containing component cracking is by the chlorine purifier upper outlet, sucks the bubbling chamber and water dissolution forms hydrochloric acid by vacuum pump, recycles machine along pipeline.All the other mixed oil and gas generate paraffin, fuel oil and the fuel gas mixture that needs respectively after the condensation separator cooling.Pass through separation, cooling, rectifying and filtration again, after collector is collected respectively one by one, just obtain fuel oil and fuel gas product.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these embodiments.Therefore, protection scope of the present invention is limited by appended claims.
