Description
Technical field
The utility model relates to a kind of damaged tire comprehensive utilization thermo-cracking full scale plant.
Background technology
Along with the develop rapidly of automotive industry, scrap the quantity rapid growth of tire every year.These damaged tires mostly are considered the rubbish air storage or by landfill simply with incinerate.The bulk deposition of damaged tire not only takes up room and ploughs, and pollutes the environment, grows mosquito, communicate illness.A large amount of stackings of damaged tire have simultaneously also been buried hidden danger for fire, and all there is the report because of damaged tire burning causing fire in states such as Canada, the U.S. and Japan.Although landfill can be avoided the generation of fire, can cause ploughs reduces and phreatic pollution.Burn and then can increase content of harmful such as carbonic acid gas in the atmosphere, nitrogen peroxide, hydrocarbon polymer.Therefore cause " white pollution " the same with used foam plastics, the someone claims that junked tire is " black pollution ".Environment-friendly treatment method to this black pollution is a regenerative use technology at present.Regenerative use technology can be divided into the simple regeneration utilization and modification regeneration utilizes two big classes.The simple regeneration utilization has occurred grinding technology such as fine glue powder as damaged tire renovation and junked tire at present, and these method technologies are simple, but the poor performance of regeneration product, deficiency in economic performance, and the pollution problem that can not fundamentally solve waste rubber.The modification regeneration utilization is ideal damaged tire recovery method, and wherein the main path of modification is the Pintsch process technology, and the wheel tyre material block that is about to cut feeds a locking equipment to carry out heat and heat up in a steamer, and rubber for tire is cracked into combustible gas and liquid oil, and the carbon black product.This method had both been avoided the pollution of damaged tire to environment, turned waste into wealth again, had produced considerable economic, therefore more and more was subjected to the attention of various countries.But in the implementation procedure of pyrolysis technology, especially this technology is expanded to the process of large-scale industrial production from laboratory scale, can successfully design the key that the cracking apparatus that satisfies cracking condition is a problem.Its design quality will directly have influence on the realization of this technological process and the costs and benefits of whole production.From documents and materials, external this respect research at present relatively success what mainly contain people's exploitation such as Canadian R.coy is the cracking apparatus of heat-transfer medium with the melting salt.This equipment adopts double-deck heating disc horizontal type structure, advantage be easy for installation, seal request is low, more easily realize vacuum operating.But it is very high to operational requirement, if accidents such as outage take place operational process, in case melting salt cools off, solidifies, will cause scrapping of a whole set of equipment.The domestic cleavage column that also designs the revolving drum structure.This apparatus body turns round with certain speed, and for improving heat-transfer effect, the body outer wall is provided with hurricane band simultaneously, and inwall is provided with fin.Because this structure exists the dynamic seal problem of major diameter revolving drum, therefore be difficult for adopting the zone heating mode, and if only adopt the single hop type of heating, then the scission reaction concentration zones is the cold zone of stack gas, for guaranteeing that the rubber fritter reaches certain cracking temperature, must have higher input gas temperature.Strengthen in treatment capacity, during pyrolyzer body length lengthening, problem is more outstanding.In addition between body outer wall hurricane band and the shell also for dynamic seal, and flue gas flow rate is generally up to more than the 20m/s in the scission reaction, so stack gas easily is short-circuited, and improperly will reduce heat transfer coefficient greatly if control.
Summary of the invention
The purpose of this utility model provides a kind of damaged tire comprehensive utilization thermo-cracking full scale plant.
It has airtight vertical tower body, be provided with scraper whipping appts, tire opening for feed and splitting gas outlet in the tower body upper end, be provided with the hollow heating disk in top, lower hollow cooling disk in the tower body successively, and communicate carbon black outlet at the bottom of tower body has scraper whipping appts and tower with stack gas distribution system, the cooling water intakeoutfall collection case in the tower body outside respectively.
This cracker turndown ratio is big, and cracking performance is good, and running is reliable continuously, and labour intensity is little, is a kind of well behaved apparatus for thermal cleavage.Its principal feature is as follows:
1) energy consumption is little.General only consume fuel oil at the beginning of driving, the combustible gas that do not coagulate that can directly cracking be produced after stable is directly introduced combustion chamber supply burning, and can be used as the thermal source of waste heat boiler after the high-temperature flue gas discharge through the cracking apparatus heat exchange, thereby effectively realize energy-conservation and environmental protection;
2) regulate control conveniently, adaptability is strong.Angle that can be by changing the disk number of plies, raker stirrer leaf and quantity, top master's rotating speed of motor wait regulates the residence time of block rubber on heating plate, to adapt to the cracking of tyres of different types;
3) operation is airtight, and inclusion-free enters, and no splitting gas leaks, and quality is guaranteed with safety;
4) weight of equipment is light, adopts vertical structure, and floor space is little;
5) running is stable, easy to operate.
