Description

Industrialization waste plastic oil refining reactor

Technical field

The utility model relates to a kind of refining equipment, is specially a kind of industrialization waste plastic oil refining reactor.

Background technology

Along with science and technology and the develop rapidly of industrial economy and human lives's demand, the consumption of various plastics grows with each passing day, yet the discarded white pollution that is caused of the consequent also comes seriously more; Make a silk purse out of a sow's ear for eliminating white pollution, from the beginning seventies, various for many years oil Refining Technologies and equipment are used and are given birth to, and especially China is more outstanding, only is that patent documentation is delivered nearly 200 parts more than, and the refining equipment patent accounts for about 60%.With the utility model is example, has following defective with regard to present disclosed patent documentation analysis; 1. the waste plastic oiling is thermo-negative reaction, and heat is that the wall by equipment passes to plastics, and the wall temperature surpasses 250 oil molecules when spending and produces condensation reaction on the wall surface, and the wall surface just generates coke.When coke thickness reaches 10 millimeter, heat flux will weaken about 50%, and the throughput of equipment will reduce, and energy consumption increases, so require equipment should in time coke be removed in process of production to guarantee heat flux.But that is narrated in numerous utility model equipment patents scrapes Jiao or agitator, does not also accomplish this point; As everyone knows; Equipment (reactor) belongs to pressurized vessel, when factory makes, the reel welding will produce ovality, and the device fabrication standard is to allow certain degree of deviation, equipment (reactor) at high temperature moves when producing, the metal of equipment different directions under the effect of thermal stresses deforms in various degree, require thus in the equipment scrape coke installation or agitator possesses extremely strong adaptability to changes and handiness in production run.2. equipment (reactor) is normally vertical, horizontal two kinds, equipment (reactor) in production run with the liquid phase section, the vapour phase section exists, because equipment (reactor) is that metal is conjuncted, the wall temperature of vapour phase section equipment also is higher than the green coke temperature simultaneously, the oil gas molecule also can produce condensation reaction with the high temperature wall simultaneously, the phenomenon of wall green coke also exists, along with the production run time lengthening, the thickness of wall coke also increases thereupon, and the gas phase section space of equipment (reactor) diminishes even blocks, and equipment just can't carry out production run.3. objectively the heat flux of equipment is the shape restriction that has been subjected to equipment, therefore limited to heat flux, the throughput of also having limited to equipment simultaneously, how to strengthen simultaneously the plastics oiling in certain temperature, required heat gasifies, consult all patent documentations at present, nearly all be the way that improves the temperature difference, this method has following drawback, 1. at the bottom of the liquid yield, carbonization phenomenon is serious, 2. oil quality difference reason is that insatiable hunger is closed hydrocarbon content up to 80%, and this kind oil product antioxidant capacity is poor, very easily generate the meltability colloid and with peculiar smell very easily variable color 3. at high temperature the equipment metal lose rigidity easily, the production cycle of equipment is shortened, and with danger.

Summary of the invention

The utility model is serious for the carbonization phenomenon that the equipment that solves cracking waste plastics in the prior art and use exists, the oil product antioxidant capacity is poor, the equipment metal loses problem such as rigidity easily and a kind of industrialization waste plastic oil refining reactor is provided under the high temperature.

The utility model is realized by following technical scheme, a kind of industrialization waste plastic oil refining reactor, comprise inner barrel, inner barrel is provided with the fused salt chuck outward, be provided with reciprocating type interlock agitator in the inner barrel, reciprocating type interlock agitator comprises by motor-driven screw rod, is connected with under the screw rod and stirs axle, be connected with and stir thick stick around stirring axle, stir the thick stick end and be connected with and scrape the charcoal device.

Inner barrel is provided with belt instlated tubular, and the inner barrel inwall is provided with belt radiator element.The cylinder inboard wall vertical section is established the belt radiator element of spiral, sheet and sheet spacing are the pitch of screw shaft, 10-20 centimetre of selection of radiator element fabric width, and inner core wall vertical section has been installed the radiator element heat interchanging area that has been doubled and redoubled, strengthen heat flux, improved the intellect of locating that heat utilization efficiency has strengthened reactor.Wherein place, the adjacent boundary of inner barrel liquid and gas section is provided with annular instlated tubular, because inner barrel is that metal is conjuncted, reactor is in working order the time, and the coke that gas phase section wall generates is difficult to remove with device.Belt instlated tubular of the present utility model has just been stopped the condition of gas phase section wall generation coke, reactor is in working order the time, can use refrigerant (air or water) pump admission port, the other end control of export is below 250 ℃, and this method i.e. not only practicality but also safety of economy simply not only.

Scrape the charcoal device and comprise and stir the interior square tube that thick stick is connected, be with outer square tube on the interior square tube, interior square tube and outer square tube overcoat have the telescopic joint protective sleeve, are with coil tension spring on the interior square tube, and foreign side's pipe coupling has chuck, is connected with graphite slider on the chuck.

The utility model compared with prior art has following beneficial effect: 1, the utility model vertical section in the reactor inner barrel adds radiator element, has effectively increased heat interchanging area and has improved heat flux, and then increased the treatment capacity of waste plastic.2, the utility model is provided with the difficult problem that the instlated tubular that goes in ring has thoroughly solved reactor gas phase section wall green coke between reactor inner barrel gas phase section and liquid phase section.3, the utility model is provided with reciprocating type interlock agitator in reactor, and the agitating function in special-shaped still is particularly outstanding.4, the utility model being provided with stirred thick stick and this device of graphite slider, solved because of making thermal stresses to make the reactor distortion be difficult for the difficult problem of decoking, and graphite slider has played provide protection to the reactor wall.5, the utility model simple, easy to operate, be applicable to suitability for industrialized production fully.
