Description
Technical field
The present invention relates to a kind of with plastic waste be converted into oil equipment, especially a kind of by thin film evaporation with plastic waste be converted into oil the oiling device.
Background technology
As everyone knows, nearly all kinds plastic waste environment as refuse pollution and can not be utilized by people as resource.In recent years, people manage to develop pollution-free recovery and utilize plastic waste to generate the method for processed oil.Temperature and catalyzer are essential condition in the cracking waste plastics process, but the what is more important cracking apparatus.Because the poor thermal conductivity of plastics, and many plastics can become the high-viscosity melt that is difficult to carry when heating.Secondly plastic waste can produce deposition of carbon in reactor wall when pyrolytic decomposition, causes the discharging difficulty, so the cracking of plastic waste needs special equipment.Use cracking reactor at present both at home and abroad, its kind is more, and wherein slot type, tubular type and fluidized bed reactor are most widely used.
The characteristics of groove type reactor are plastic waste mixing stirrings in the decomposition course in groove, and material is in the thorough mixing state, take the indirect heating controlled temperature to reach and give birth to olefiant proterties.This method material residence time in reactor is long, and the heating tube surface has charcoal to separate out can to cause conducts heat badly, needs periodic cleaning and discharges difficulty.
Pipe reaction is to decompose plastic waste with heavy oil fusion formula, enters decomposing furnace again, and it is even that this method is mainly used in raw material, generates liquid monomeric polystyrene easily.Helical reactors adopts helical stir, conducts heat evenly, and decomposition rate is fast, but can not realize lighting fully to the slower polymkeric substance of decomposition rate.
The fluidisation hearth reactor generally is to add plastic waste by screw feeder, makes it to be in fluidized state with the bog that solid granule carrier and bottom enter, and decomposes composition and derives reactor with ascending gas, and m-benzoamino-semicarbazide is made branded oil.Fluidized bed reactor is simpler to handling when the 400-500 ℃ of single raw material such as easy pyrolysated polystyrene technology, oil recovery rate height.But the plastic waste to other classes can't resolve into oil.
Summary of the invention
The object of the present invention is to provide a kind of device, the plastic waste liquation is driven scraper plate by the rotor in it be evenly distributed on the scraper plate membrane type thermal decomposer inwall, make liquation under the inwall action of high temperature, resolve into gaseous state and solid-state.
The present invention is achieved by the following scheme: a kind of scraped film type thermolysis plastics oiling device that plastic waste is converted into oil, bag is scraped motor, support, it is characterized in that: one side is provided with an opening for feed on the top of vertical chuck cylindrical tube, opposite side is provided with thermal oil outlet, bottom one side is provided with a heat conductive oil inlet, the bottom is provided with the Hui Ji district, connect disposal box by the straight method of dull and stereotyped screw rod, inner chamber has a vertical rotating shaft, have several scraper plates in the rotating shaft; a commentaries on classics axle Even scraper plate and rotates under the drive of motor, rotating shaft is fixed by flange, be inlaid with a chuck layer on the vertical chuck cylindrical tube inwall, between scraper plate and its interior cover inwall gap arranged, its top also is provided with a surge chamber.
The two ends of above-mentioned surge chamber are by wear ring mechanical seal.
The inwall of above-mentioned vertical chuck cylindrical tube adopts accurate boring polished finish, and material is the stainless steel of corrosion-resistant and high-temperature resistant.
Adopt the present invention, liquid was very shortly just decomposed rapidly in the inwall residence time, easy temperature control system, and heat energy utilization rate height, but continuously feeding are suitable for scale operation.Have simple in structure, long service life, inwall non-scaling, characteristics such as pollution-free.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment
In Fig. 1, scraped film type thermolysis oiling device of the present invention, bag is scraped motor 1, support 2, vertical shell 20, a side is provided with an opening for feed 8 on the top of vertical chuck cylindrical tube 20, bottom one side is provided with a heat kerosene import 14, opposite side is provided with heat kerosene outlet 9, the bottom is provided with Hui Ji district 16 and disposal box 19, inner chamber has a vertical rotating shaft 12, have several scraper plates 13 in the rotating shaft 12, rotating shaft 12 can be rotated under the drive of motor 1, and rotating shaft 12 is by flange 7,15 is fixing, be inlaid with a chuck layer 11 on the inwall, one gap 10 is arranged between scraper plate 13 and the chuck layer 11, and the feed flow materials flow is moving, and the top of vertical chuck cylindrical tube 20 is provided with the surge chamber 5 of a band thermal insulation layer 6, there is pneumatic outlet 4 centre of surge chamber 5, and two ends are by wear ring 3 mechanical seals.
The inwall of above-mentioned vertical shell 20 adopts accurate boring polished finish, and material is the stainless steel of corrosion-resistant and high-temperature resistant.
During work, the thermoplast liquid that is decomposed tangentially enters the inwall of oiling device from the opening for feed 8 of scraped film type thermolysis plastics oiling device, motor 1 drives rotating shaft 12 and scraper plate 13 rotations, owing to be subjected to centrifugal force, the induced effect of gravity and scraper plate 13, feed liquid is along evenly trickling naturally downwards of inwall, form the thick book rete 10 of 3mm, under the effect of 400--450 ℃ of inwall high temperature, the liquation of shaped liquid film is heated and decomposes rapidly, generate upwards evaporation of gas, gas 4 enters gas catalysis device reaction by surge chamber 5 from the air outlet, and pneumatic outlet 4 usefulness flanges are connected with catalyst converter.The solid carbon black that evaporates falls downwards naturally along inwall, drops to Hui Ji district 16, sucks disposal boxes 19 by Hui Ji district 16 again, straight French 7 of dull and stereotyped screw rod and flange 18 be used for controlling Hui Ji district 16 deposit the ash amount how much.4 enter gas catalysis and react from the air outlet by surge chamber 5 and be subjected to high temperature liquid material to resolve into gasiform gas, pneumatic outlet 4 usefulness flanges are connected with catalyst converter.
