Abstract
The utility model relates to a catalytic cracking furnace for preparing gasoline and diesel oil from waste plastics and waste rubber. The utility model is characterized in that a rotating shaft with a scraper is arranged in a boiler body in order to scrape coke deposit at a boiler bottom and promote heat transfer and mixing, and the scraper can be in a linear type or an arched type. The rotating shaft is provided with a vane used for pushing cracking gas to move upwards. A coal furnace and a flue gas jacket around the boiler body are used as heating equipment. The catalytic cracking furnace belonging to dry burning equipment has the advantages of high thermal efficiency and high heating speed. Productivity can be increased, and the yield of the cracking gas can be also increased. The cracking furnace has no pressure, only needs to control temperature, and can be used in the simplest process of plastic cracking.
Description
The utility model relates to plastic waste, waste rubber produces liquid hydrocarbon mixture, as the catalytic cracker of gasoline, diesel oil etc.
Depleted plastic garbage, rubber tyre quantity are surprising in the world at present, because of the difficulty of degrading, have caused day by day serious environmental to pollute, existent environment of people are formed threaten.Waste rubber enormous amount is wherein handled more difficultly, and for plastics and rubber with the polymer form are reduced into low molecule fuel oil, people are that the processing unit of continuing to use petroleum cracking is carried out cracking so far, and its effect is very poor.In existing cracking waste plastics stove, the lighting end in the oil becomes pitch shape and hard coaly carbide---carbon deposit because of the oxygenizement that is subjected to high temperature air, and very fast meeting forms thick carbon film at furnace bottom, has a strong impact on to conduct heat and cracked efficient.The existence of carbon deposit not only makes cracking tolerance, oil pump capacity reduce, and the production cycle prolongs, and consumption of coal is increased, and bottom temperature is too high, and furnace bottom is yielding, and the life-span is short.Carbon deposit also may set off an explosion under certain condition, and is very dangerous.In addition, in existing plastic cracking stove, because of lacking stirring action, the effect of catalyzer is not in full use, and the cracking vapour that has generated can not be discharged smoothly.
The purpose of this utility model is the above-mentioned difficulties that will overcome prior art, and provide a kind of improved usefulness plastic waste waste rubber to produce the catalytic cracker of gasoline, diesel oil, make furnace bottom can not form carbon film, and can strengthen stirring action, thereby improve the factor of created gase of pyrolyzer greatly the melting plastics.
Solution of the present utility model is: this catalytic cracker comprises tubular pot body 1, feed-pipe 2, slag notch 3, splitting gas comb 4 and heating installation, it is characterized in that the rotating shaft 7 of in the said pot body 1 belt scraping plate 8 being housed, scraper plate is contained in the rotating shaft bottom near place, the bottom of a pan, also promotes to conduct heat and mix in order to the carbon distribution that strikes off the bottom of a pan; Rotating shaft 7 and scraper plate 8 are by thrust block 9 supportings on pot top.
More than also can install in the said rotating shaft a pair of or severally to blade 10, can quicken splitting gas during rotation and discharge by the top comb.
The heating installation of this catalytic cracker can be coal furnace 6 and be located at pot body stack gas chuck 12 on every side.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the longitudinal profile synoptic diagram of this catalytic cracker.
Referring to accompanying drawing, catalytic cracker top is pot body 1, and the bottom is a heating installation, and heating installation can be the coal furnace 6 among the figure, also can be steam heating or electrically heated etc.Pot body 1 is a round shape, along medullary ray rotating shaft 7 is housed in the pot body, and the scraper plate 8 that strikes off carbon deposit is equipped with near place, the bottom of a pan in the rotating shaft bottom, between the scraper plate and the bottom of a pan 5 certain interval is arranged, and the carbon deposit and the residue in the bottom of a pan can be struck off during rotation, and can play agitator.The shape of scraper plate can be a linear pattern radially, also can be arc line type, the blade shape of similar centrifugal blower.Help carbon deposit and residue are scraped to the peripheral part during rotation of arc line type scraper plate, discharge by slag notch 3.Rotating shaft 7 is generally intermittently and rotates, and rotating speed rotated a few every 20～30 minutes and gets final product the end of than.Rotating shaft can be rotated by handle 15, and also useable electric moter drives.Under the effect of scraper plate, catalyzer mixes more even with the melting plastics, reacts more rapid; Also more help splitting gas and from liquid plastic, overflow, improve gas production rate.Rotating shaft 7 and scraper plate 8 etc. are by thrust block 9 supportings on pot top.
Above scraper plate, a plurality of blades 10 are housed also in the rotating shaft 7.Cause upstream when being in blade 10 rotations on the liquid level, can quicken splitting gas and discharge, and help improving the output of splitting gas to top comb 4.
The heating installation of this catalytic cracker adopts coal furnace 6.Plastic waste, waste rubber in this coal furnace direct heating pot body 1, because of belonging to dry combustion method equipment, the thermo-efficiency height, rate of heating is fast.In order to make full use of the waste heat of coal furnace, this pyrolyzer is surrounded by stack gas chuck 12 around the pot body.Flue gas in the coal furnace is discharged behind chuck 12, and temperature is lower, and wherein heat is fully used, thereby can reduce energy consumption and fuel cost.
In order to guarantee that pyrolyzer accurately by the processing requirement operation, is equipped with tensimeter 11 and safety valve 14 etc. at pyrolyzer pot body 1 top.Thermometer 13 is housed, to observe temperature of cracking gas at any time on splitting gas comb 4.
There is a retaining board 16 feed-pipe 2 bottoms, can rotate around hinge 17, play check valve, open during charging, close automatically at ordinary times.
The bottom of a pan 5 of this pyrolyzer adopts high temperature materials to make, and can bear all the year round and spend high temperature more 1,000, can delamination, oxidation and distortion.
The cracking of this stove plastic waste is a raw material with polyethylene, polypropylene or polystyrene etc. mainly, is dropped in the stove by feed-pipe 2, through the catalysis heating pyrolyze, polymer long-chain plastics is reduced into low molecule fuel oil, mainly is compositions such as gasoline, diesel oil.The comb 4 of splitting gas links to each other with equipment such as condensing heat exchanger, store oil separator, liquefied gas cleaner and rectifying decomposing furnaces successively, forms unique complete production system.Last availability matter, the outward appearance product extremely similar to regular price gasoline, diesel oil.
The pyrolyzer of the utility model belt scraping plate and blade is the removing carbon phenomenon effectively, strengthening heat transfer, the fusing and the gas generation process of quickening plastics.Can also the fortifying catalytic agent and the mixing of melting plastics, can boost productivity greatly, increase the output of reacted gas.This pyrolyzer does not have pressure with the direct dry combustion method plastics of fire in the stove, only need controlled temperature, belongs to the simplest process in the plastics cracking.To the size of plastic raw materials, clean level does not have particular requirement.The waste residue that pyrolyzer is discharged is the industrial raw material carbon black, is easy to reclaim with scraper plate.Owing to eliminated carbon deposit, thermo-efficiency improves, and consumption of coal significantly reduces.In a word, this equipment volume is little, and cost is low, produces easyly, and it is fast to heat, and gas production rate is big, very is fit to China and other developing country uses.
