Abstract
A technology using regenerated energy from waste plastic safe production adopts a vertical thermal cracking reactor with a mixer, a pressure and temperature sensor equipped on the top and a steam inlet pipe, wherein steam exhausting outlet and steam intake valve are opened after oil refining finished to feed steam into the reactor with mixing, then the steam value is closed and the scum hole at the bottom of the reactor is opened to discharge slag. The waste steam is fed into a waste steam treatment pool, the overflowing mouth of which is connected with an adsorption filter tank, and the filtered water is recycling used or exhausted. The technology can not cause blocking of oil outlet, so the work efficiency is greatly improved; the temperature of the reactor is rapidly decreased because of cooling and tap slag, while the steam can reduce the dust of the slag in the reactor and does not cause the secondary environmental pollution; the technology is provided with the pressure and temperature sensor, the control system will send alarm sound when beyond set temperature and pressure, so those skilled in the art can treat in time to avoid safety accident.
Description
One, technical field
But the present invention relates to a kind of technology that various oiled waste materials such as waste old, waste or used plastics, refuse plastic are refined oil under the safety and environmental protection state.
Two, background technology
Along with the development of technology and the progress of society, waste old, waste or used plastics and refuse plastic also increase progressively day by day, but growing tension of oil fuel resource in this case, utilizes waste old, waste or used plastics to carry out pyrolysis and becomes oil fuel to form a kind of new industry on the other hand.The apparatus for thermal cleavage of existing oil refining by waste plastic is mainly by vertical, horizontal two kinds of forms in the market.
Because being thermally cracked to oil fuel, waste rubber, plastic waste need certain temperature, and be basic under anaerobic state the pyrolysis olifiant gas, when thermo-cracking is finished substantially, in most thermal crackers a certain amount of flammable gas can remainingly be arranged, if having slightly of thermo-cracking is not thorough, it is more that combustible gas is known from experience generation.
At present, vertical refining equipment generally is once to throw a full still material heating pyrolyze, does not stir, and the oil plant yield is lower, and the production cycle is longer.Existing refining equipment, when slagging tap after thermo-cracking finishes, device cooling needs considerable time, and when opening door and slag tap, the combustible gas that has in air and the device mixes, and so is easy to cause bin gate flame, in addition, also can cause the pollution of environment when slagging tap.And horizontal rotation oil refining processor, be easy to stop up fuel-displaced gas port, in equipment, produce pressure, and the speed that pressure rises is very fast, and the general operation personnel are difficult to perceive discovery, generally all is just to find after accident takes place, light distortion that bin gate is risen, heavy then handle assembly weld seam spreading is in case weld cracking will cause firing accident.
Three, summary of the invention
The technical problem to be solved in the present invention is; A kind of technology of can safety and environmental protection in utilizing waste rubber, waste plastic oil-refining producing is provided, in utilizing waste rubber, waste plastic oil-refining process, security incident no longer occurs, and do not produce secondary pollution when slagging tap.
The technical scheme that solution the technology of the present invention problem is taked is: be provided with a major axis agitator in the middle of vertical thermally cracked kettle, the stirrer shaft upper, middle and lower are equipped with paddle; Opening for feed, fuel-displaced gas port all are located at the thermally cracked kettle top, and its top feed adopts the pusher feeder of piston; Be provided with a pressure-temperature sensor at the top, pressure-temperature sensor inserts in the still from the top; Fuel-displaced gas port connects an oil gas steam ailevator through an oil and gas pipe road, be provided with a baffle plate variable valve in oil gas steam ailevator; A mouth connects the steam treatment pond through steam exhaust pipe on the oil gas steam ailevator, and another mouthful connects the pot type condenser, and the pot type condenser inventor has declared patent, and automatically controlled part colleague technician all can design voluntarily, does not all do detailed description at this.
For environmental protection is slagged tap, be provided with one at the thermally cracked kettle top and advance vapour pipe, enter the vapour pipe outer end and connect a vapour generator.During works better, controllable register variable valve closed steam exhaust pipe mouth makes oil gas enter the pot type condenser; After oil refining finished, the controllable register variable valve was opened the steam exhaust-gas mouth of pipe, opens the steam inlet valve, feeds steam in vertical pyrolysis still, and stir on logical steam limit, limit, and steam off valve after 8-10 minute is opened the slag notch of vertical thermally cracked kettle bottom and can be slagged tap.
Simultaneously, exhaust steam enters oil gas steam ailevator and enters the steam treatment pond from steam exhaust pipe from the fuel-displaced gas port at vertical thermally cracked kettle top through the oil and gas pipe road, the overflow port in steam treatment pond connects the adsorption filtration pond, and the water cycle after twice adsorption filtration is used or discharging; Be provided with sewage draining exit in the steam treatment basin bottom, can regularly carry out blowdown and handle.
Positively effect of the present invention is: adopt the vertical thermally cracked kettle of belt stirrer, can not cause the stifled match of fuel-displaced gas port, working efficiency can improve greatly, can not only satisfy the oil refining process requirement, and oil quality is good; The employing steam cooling is slagged tap, and temperature in the kettle is lowered fast, and steam has reduced the dust of slag charge in the still again simultaneously, and the Shi Buhui that slags tap causes second environmental pollution; Pressure-temperature sensor is installed, surpasses design temperature or pressure, Controlling System is promptly sent chimes of doom, and the technician just can in time handle, and security incident can not take place.
Four, description of drawings
Accompanying drawing is the artwork of the technology of the present invention.
Five, embodiment
Adopting 1.8 meters-2 meters high 4 meters two of a diameter is arcual vertical thermally cracked kettles 5, the centre is provided with an agitator 4, longer because of stirrer shaft, the centre is fixed on thermally cracked kettle 5 inwalls through a support sleeve and agitator bracing frame 6, and upper, middle and lower are equipped with paddle; Opening for feed, fuel-displaced gas port all are located at the thermally cracked kettle top, and its top feed adopts the pusher feeder 2 of piston, on one side charging stir on one side; Be provided with a pressure-temperature sensor 14 at the top, pressure-temperature sensor 14 inserts in the still from the top, according to processing requirement, and operating pressure 0.8-1kg/cm in the still
2, working temperature 300-350 ℃, when the still internal pressure surpasses 1.5kg/cm
2Or temperature is when surpassing 380 ℃, and Controlling System is promptly reported to the police.
The fuel-displaced gas port at top connects an oil gas steam ailevator 12 through an oil and gas pipe road 13, is provided with a baffle plate variable valve 11 in oil gas steam ailevator 12; A mouth connects steam treatment pond 8 through steam exhaust pipe 10 on the oil gas steam ailevator 12, and another mouthful connects the pot type condenser.During works better, controllable register variable valve 11 closed steam exhaust pipe mouths make oil gas enter the pot type condenser; After oil refining finishes, controllable register variable valve 11 is opened the steam exhaust-gas mouth of pipe, open the steam inlet valve, feeding logical steam limit, 120-130 ℃ of steam limit in vertical thermally cracked kettle stirs, steam off valve after 8-10 minute, open the slag notch 7 of vertical thermally cracked kettle bottom, the lime-ash of this moment is relatively moister, just can not pollute when slagging tap.
