Description

Equipment for suspend catalytic pyrolysis flameless combustion plastics or rubber discarded object

Technical field

It the utility model is related to a kind of combustion equipment, and in particular to one kind is used for the catalytic pyrolysis catalysis oxidation nonflame combustion that suspends Burn the combustion equipment of plastics or rubber discarded object.

Background technology

With the development of the social economy, the referred to as junked tire of black pollution thing and the referred to as useless modeling of white pollution thing The high polymer material yield of the difficult degradations such as material is increasingly huge, has brought serious problem of environmental pollution.

At present, the tire whole world only scrapped is able to only the 15~20% of recycling, China often over 1500000000 Junked tire is also up to more than 300,000,000 bars caused by whole year in 2016, and weight is more than 10,000,000 tons.For a long time, it is increasing useless A great problem of the old tire into environmental protection.Therefore, how rationally, efficiently turned into society using junked tire to close extensively The problem of note.

Various junked tires according to its different main component fluctuation range of former purposes be rubber 30~55%, activated carbon 20~ 36%th, sulphur 0.5~3.0%, softening agent（Oil）1~22%, zinc oxide 0.5~2.6% plus sulphur auxiliary agent 1~13%, fiber 0~18%, steel Silk 2~17%（Wherein truck radial bead wire 15~40%）, the basis of same tire material is relatively simple and stablizes, Substantially rubber 50%, charcoal 25%, steel wire 15%, other additives 10%, its contained element charcoal nitrogen hydrogen-oxygen total amount>88%th, water<1%th, sulphur Average 1.5%, calorific value is with steel wire changes of contents, mean calorie 7790kcal/kg.

Currently, junked tire recycling recycles and may be summarized to be three major types operational plate.First, junked tire renovation is again Manufacture, but prototype amount usable is seldom, is only the intact a part of damaged tire of carcass, the amount less than 1%.Second, as raw material profit With production reclaimed rubber and rubber powder etc..Only China's reclaimed rubber yield in 2016 exceedes 4,400,000 tons, reclaimed rubber powder yield reaches 360000 tons, but the preparation of vulcanized rubber powder need to be carried out, it is necessary to energy intensive equipment under the conditions of cryogenic freezing；Produce reclaimed rubber Process can also produce extremely intractable waste gas, and secondary pollution is serious, and energy consumption is very high, and the profit for producing reclaimed rubber is low, west state Family has gradually eliminated the mode of this processing scrap rubber mostly, and in addition, China also creates large-scale " malicious runway " Event.Third, as fuel utilization, including cracking liquefaction gas and as furnace fuel.

The cracking technique of junked tire mainly has thermal cracking, catalytic degradation and the class technique of microwave depolymerization three.First kind hot tearing Solution technology mainly includes：1）Normal pressure inert gas（Scrap rubber is heated to 500 DEG C）Pyrolytic technique；2）Vacuum（In stagnation pressure 2 Scrap rubber is cracked under the conditions of~20kPa, 510 DEG C of temperature）Pyrolytic technique；3）Fuse salt（Tire fragment is immersed into lithium chloride/chlorine In the eutectic mixture for changing potassium, 500 DEG C, nitrogen medium are heated to）Pyrolytic technique.From the point of view of thermal cracking equipment, have and represent The thermal cracking process of property includes vacuum moving bed, two sections of moving beds, fluid bed, continuous ablation bed and rotary kiln thermal cracking process. Second class catalytic degradation technology is given up using the lewis acids such as zinc chloride, stannic chloride and antimony iodide melting salt catalyst The method of old tire degradation of rubber, alkali metal or alkaline earth metal carbonate can be added in scrap rubber as auxiliary catalysis during implementation Agent is to increase the isobutene mass fraction in pyrolysis product.3rd class microwave depolymerization process, it is that will fill broken bulk Container of the damaged tire using nitrogen as medium is put into microwave generator, the method that the microwave using frequency as 2450MHz heats cracking. Above-mentioned three major types junked tire cracking technique all includes raw material prefabrication system, pyrolysis reactor system, gas-oil recovery point From system, solids recovery system.Its cracking apparatus is the key point of whole technique, but design meets splitting for technological requirement at present Solution equipment is remained in very big difficulty, and energy consumption and secondary pollution are also the problem of needing to continue research.Currently, China's cracking technique phase The exploitation of pass equipment and the analysis application study of product are mostly at the early-stage, how to realize pollution-free, serialization, automation hot tearing The problem of recycling of solution product is to be resolved.

In terms of by the use of junked tire as kiln alternative fuel, it is concentrated mainly on and is used for using junked tire replacement fire coal Boiler generating, burnt lime, blast furnace converter ironmaking and cement kiln.Wherein cement kiln uses junked tire as alternative fuel, its side Method can be summarized as three kinds, and method one is to put into junked tire in rotary kiln end or in the middle part of rotary kiln or dore furnace with overall Bottom progressively after-flame, burning velocity is slow, and the thermal efficiency is low, and clinker quality fluctuation, typically normal preheating and baking stove and preheating kiln are adopted Make alternative fuel use with overall junked tire, typically fed by one of precalcining bottom section special door.Method two It is the cone that junked tire processing cuts into pieces out of kiln hood input rotary kiln to fall and burn on clinker or from kiln tail predecomposition furnace Portion, which puts into or put into from kiln tail smoke-box, burns, and its burning velocity is partially slow, and ignition temperature is relatively relatively low, reaches effect same needs more More energy, the thermal efficiency are relatively low, it is impossible to the equivalent effect of coal dust identical calorific value with rubber is produced, furthermore, objectively fall in clinker It is upper burning easily formed reducing atmosphere produce reduction clinker, from kiln tail smoke-box or dore furnace tapering input cause predecomposition furnace tapering to The easy skinning of smoke-box, to the influence on kiln system operating mode existed facts.Method three be by junked tire crush be rubber granule or rubber Powder, another nozzle being set up in parallel using the coal powder in kiln head burner with rotary kiln, blowed into rotary kiln rubber granular material or Rubber powder, this method burning velocity is very fast, and ignition temperature is higher, and efficiency of combustion is higher, alternative division header coal, but power consumption of polymer processing It is higher, and tail coal can not be substituted.And fuel needed for fuel ratio rotary kiln end needed for dry cement production line dore furnace is high near 50%, dore furnace is generally dore furnace 60~65% with kiln hood coal proportion：Kiln hood 35~40%.In fact, current, even ripple Orchid, Ukraine etc. are a large amount of by the use of junked tire etc. as the cement plant of manufacture of cement alternative fuel, despite the use of junked tire Plastics etc. can be accomplished significantly to substitute fire coal, but due to art methods and equipment problem, it is burnt till clinker and fired using replacement The heat consumption of material is actually greater than the heat consumption using coal dust, and identical calorific value can not produce equivalent effect, on the one hand cause wave Take, on the other hand, because need to more consume junked tire amount, frequently resulting in the zinc oxide brought into excessively influences the condensation of clinker Time and intensity, and do not find solution maximum replacement amount can only be determined with experience and lessons.

In terms of waste plastics, a large amount of caused waste plastics include discarded thermohardening plastics and thermoplastic.Thermohardening Plastics mainly have phenolic resin, Lauxite, epoxy resin, furane resins, unsaturated polyester resin etc., and used heat hard plastic is big Mostly discarded casing for electric appliances or cullet steel.Thermoplastic mainly has PE, PP, PVC, PS, PET, ABS, PC etc., wherein PVC Occupy larger proportion.

Currently, the regeneration of waste plastics is included as raw material by the use of and as the broad aspect of fuel utilization two.Waste plastics is made It is kneaded as plastic products or is kneaded with wood chip again and be used as composite wood system by the use of including adding solvent and new resin for raw material Product add other fillers and fiber to be kneaded as mixed mould plate material, packing case, and as earth material etc., in waste plastics as former Material use aspects achieve huge achievement really, also generate good economic benefit, but also add simultaneously and utilize process In secondary pollution, reduce the class and service life of product, and bring the serious of many secondary use products applications Environmental pollution and the directly a wide range of interior Health cost to population of adolescent are reported, and waste plastics is as its valency of the utilization of raw material The absolute predominance of lattice has also hit the sound development of Plastics Industry.

In terms of waste plastics is as fuel utilization, because waste plastics contains substantial amounts of resin, and fugitive constituent is high, general filler compared with Low waste plastics its volatile matter 68~73%, fixed carbon 6~7%, ash content 18~22%, calorific capacity is up to 7500~8000kcal/kg （The caloric value of common waste plastics because resin material used in it is different and used in inorganic filler components are different, ratio is different and it is different, Generally 4800~10000kcal/kg）And paid close attention to, the turning sludge into fuel of waste plastics, which utilizes, mainly includes cracking waste plastics oiling With as kiln alternative fuel.Cracking waste plastics oiling technology includes thermal cracking and the existing maturation that all become of supercritical water cracking, such as Jiangxi, China Fengcheng day green stone oil product Co., Ltd, the waste plastics from oil is hot cracked or catalytic pyrolysis produces liquefaction The rate of recovery such as gas, gasoline, diesel oil are reached advanced world standards up to 70%.But objectively secondary pollution is big, power consumption is high.

And in terms of waste plastics is as kiln alternative fuel, research both domestic and external is also quite varied with applying, but can be with Summary is summarised as following four classes technical method.

First kind method, it is that will sort the waste plastics for rejecting plastic containing chlorine or use the waste plastics of thermal cracking dechlorination to be ground into Plastic powders（Typically it is crushed to below 1mm）Spray into kiln and directly burn.This method is at home and abroad most widely used, such as 《Chinese building material》（7th phase in 2001）《Cement is burnt till with waste plastics Replacing fuel》And《Sichuan cement》（5th phase in 2001）《Cement Burn till the state-of-the-art technology using waste plastics》Three river Onoda Cement Co., Ltds are described to give birth to by fuel turnaround kiln cement baking of heavy oil The technological development situation of waste plastics is burnt in examination in producing line, utilizes high heating value>7900kcal/kg waste plastics, is first taken off waste plastics Chlorine processing（It is general to crack dechlorination recovery hydrochloric acid technique using 300 DEG C of normal heatings）, waste plastics chlorinity is down to 0.6%, then Below 1mm is crushed to, while oil firing, is blown into the special pipe burner that is blown into of waste plastics from kiln hood in rotary kiln, its is small Partially larger than 1mm molding powder then sprays into kiln tail smoke-box and dore furnace lower end（That is dore furnace tapering）Interior burning, its main fuel oil 40% can be reduced.But this method one is power consumption, second, the dechlorination process complexity of waste plastics is also easy to produce secondary pollution, third, waste plastics In substantial amounts of plasticiser can also volatilize, the energy in waste plastics is wasted, and improve using cost, fourth, must be by plastics grinding Particle to below particle diameter 1mm could not produce strongly reducing atmosphere and reduction clinker, and grinding pow consumption is too high, and general enterprises are difficult to hold By.

Second class method, it is that broken be sent directly into high-temperature cement rotary kiln of waste plastics not chloride after sorting is burnt. Such as《Chinese Resources comprehensively utilize》（2002/10）《Make the technology of cement kiln fuel with waste plastics》, describe a kind of use and be free of Halogen（Fluorine, chlorine, bromine, iodine, astatine）Thermoplastic materials waste plastics be used as the method for cement kiln fuel, wait the useless of halogen element by chloride Separating plastic removes, and block plastic crushing to below particle diameter 20mm, sheet are crushed to below 30mm, utilizes the kiln hood with rotary kiln Another nozzle that coal burner is set up in parallel, the block waste plastics of crushing is blowed into rotary kiln.Such as day Bender scenery with hills and waters mud 3 cement producing lines of factory utilize the waste plastics without halogen element to make turning sludge into fuel technology with this technology always, consume waste plastics 10 in year Ten thousand tons, what it was used is 7500kcal/kg without halogen waste plastics mean calorie.But this method can only still be adapted to rotary kiln Interior, day Bender scenery with hills and waters mud factory repetition test for many years still may not apply in the decomposition on its cement producing line, and manufacture of cement Fuel height nearly 50% needed for fuel ratio rotary kiln end needed for line dore furnace, dore furnace is generally dore furnace with kiln hood coal proportion 60~65%：Kiln hood 35~40%.On the other hand, substantial amounts of plastic containing chlorine sorting in waste plastics must still be removed.In fact, work as Preceding industry unanimously thinks that the categorised collection of waste plastics is to reduce the key that waste plastics recycling utilizes, if waste PVC is classified Recovery, most of waste plastics can simplify dechlorination process, the cost of regeneration are greatly reduced.

3rd class method be after waste plastics is crushed or waste plastics crush after mixed with other materials and be pressed into fuel slug after, It is sent into kiln and is burnt with compressing fuel slug.But type fuel slug is made in this method, and objectively energy consumption is higher, it is secondary to exist Pollution, and burning velocity is partially slow during use, secondary pollution problem is difficult to handle mostly.

4th class method is to be mixed for kiln burning using waste plastics as nugget fuel and coal, i.e., first passes through waste plastics Electric heating film charging melting and fusing form so-called compression plastics, then the compression plastics of melting are cut into nugget, then, will Section plastics nugget and coal are mixed for kiln burning.But this method is in addition to processing is more complicated, energy consumption is higher, and its processing is with burning Release problem is burnt still to require study and solve.

In view of all of the above, it is evident that ground, although the high-temperature catalytic cracking of the high polymer material such as junked tire/waste plastics has pole Big potential advantages, the pyrolysis product of junked tire/waste plastics also have an advantage in terms of combustibility, and catalytic oxidation combustion The more conventional combustion technology of technology has great advantage, but is applied to water as alternative fuel in junked tire/waste plastics etc. So far there are no in terms of mud production it is any by catalytic pyrolysis and pyrolysis product burning directly in conjunction with research and practice, more have no height Warm deep catalytic cracking technology and high-temperature S removal technology directly in conjunction with research or practice.

It is well known that manufacture of cement is highly energy-consuming high pollution enterprise, current manufacture of cement needs to consume substantial amounts of fire coal, Solve the fire coal needed for manufacture of cement with alternative fuel, especially substitute dore furnace fire coal, be always industry section skilled worker Author pays close attention to and the important topic of research.How alternative fuel especially dore furnace in manufacture of cement is efficiently resolved with replacing For the efficient Utilizing question of property fuel, and maximally utilise junked tire/waste plastics resource, reduce junked tire/useless modeling Expect the power consumption of polymer processing that utilizes and cost, can be with investment way by high-temperature catalytic cracking technique and high-temperature catalytic oxygen there is an urgent need to one kind Change technology directly in conjunction with brand-new combustion equipment.
