Abstract
The invention relates to a method for using high-energy decomposing tyre to replace the traditional mechanical method. Wherein, it is characterized in that: it puts oil tyre in special explosive device; then uses industrial drug and primer to blast, to decompose and break the tyre. The invention can save energy and reduce cost, without pollution.
Description
The invention belongs in environmental project and the scientific domain and adopt the high energy fragmentation to make products such as rubber powder junked tire, make junked tire can realize resource, commercialization and recycling economy, is a kind of desirable pollution abatement, the good method of protection environment.
Along with the develop rapidly of transportation, the popularizing of particularly current car, the junked tire that countries in the world are changed every year reaches more than 700,000,000, and the scrap rubber that is produced surpasses 1,500 ten thousand tons, and wherein tire accounts for 50%.Discarding of so huge junked tire, " white pollution " that it causes as waste foam plastics now is referred to as another " black pollution " by people.Because the discarded of it will be caused great pollution and harm to environment.It is the problem that present countries in the world are felt headache most, so its improvement research has become the world today's great difficult problem anxious to be solved.To this, we have carried out relevant exploration, research and analysis in recent years.New approaches, the new technology of rubber powder produced junked tire in proposition with high energy ozone method.Through the explorations in several years, analysis, research and practice, make junked tire resource, commercialization, in resource regeneration and utilization, turn waste into wealth, pollution abatement, protection environment be a a progressive step.Thereby realize recycling economy and national economy sustainable development, this processing method is to have great economic worth and realistic meaning.
Abroad, the processing method of junked tire, at present popular is normal temperature cutting → liquid ammonia is freezing → and mechanical crushing rubber powder → rubber powder makes industrial required material, though this processing method has found outlet for junked tire, but it: 1. investment is big, build year 20000 tons of junked tire production lines of processing as German Intik Co. and need about 3,800 ten thousand marks of fund, amount to about 200,000,000 yuan of RMB, and for example: France adopts freezing-Mechanical Method fragmentation to build the production line of year treating capacity 1～1.5 ten thousand ton junked tire with the mechanical crushing and the U.S., needing fund be 1000～1,200 ten thousand U.S. dollars, amounts to about RMB 8000～100,000,000 yuan.2. production efficiency is low, energy consumption is big, cost is high.In recent years a Russian for this reason scholar just proposes to utilize blast-ozone method to handle the new technology of junked tire, but this method is an imagination because designed destructor complexity is vertical large-scale closed blast storehouse, does not see drawing and material object.Add to make and bear the big high material of detonation pressure needs, therefore, the big need 1500 of its investment～3,000 ten thousand yuan; Adding the research thinking can not be in conjunction with national conditions, can not get country supports, though done useful exploration, there is no substantial progress in process of industrialization and industrialization.Thus, the improvement method of junked tire there is no big breakthrough and progress abroad.
At home, China is the big country of junked tire, has every year 8000 ten thousand tires to scrap.Main processing method: 1. original shape utilizes 2. pyrolysis to utilize 3. three kinds of reclaimed rubber processing and utilizations.Because backward in technique, the weak effect of these processing methods, particularly secondary pollution is serious.So country's restriction is adopted.At present domestic commonly used be that normal temperature, low temperature or warm and humid pulverizing waste tire are utilized, for example: Guangzhou China flies fine glue powder company and adopts mechanical coarse crushing, the rubber powder of making in small, broken bits behind air freezing again.And for example: Huangshi second rubber plant of east wind tire group adopts mechanical shearing-roll dynamic desulfurization junked tire is made reclaimed rubber and rubber powder.Also have some enterprises to adopt external method.In a word, junked tire both domestic and external handle still be in backward in technique, investment is big, energy consumption is high, the stage of condition difference, there is no breakthrough.
We for solving the world-famous puzzle that junked tire is administered, have proposed new approaches, the new technology of high energy disintegration broken worn-out tire at present situation both domestic and external.And on the road of commercialization, obtained breakthrough progress.We are at the maximum characteristics of this improvement method of research: 1. it is lower than traditional Mechanical Method broken worn-out tire efficient height, energy consumption, can economize on electricity.2. equipment build ground less, investment is little, only is external 1/tens.3. working condition is improved greatly, and non-secondary pollution has been realized harmless treatment.4. realized resource regeneration and recycling economy, made no longer contaminated environment of junked tire.5. can realize industrialization, can build up many production lines and enterprise, can be the employment decompression for state increases income.
Main contents of the present invention adopt the processing method of high energy disintegration broken worn-out tire, are to utilize equipment such as common commercial explosive and detonator to be placed on a metal or nonmetal special explosive container, also in case or the storehouse; With the junked tire explosion; under the effect of high energy, make it disintegrate, make fragment or rubber powder rapidly less than 50 millimeters; it is again after freezing or ozone treatment; pulverize with pulverizer then; sorting just can be made into various rubber powder products; thereby make junked tire regeneration and utilization, pollution abatement, protection environment, realize recycling economy, harmless treatment.
The present invention makes the junked tire broken processing method of disintegrating fast by the high energy of explosive charge, it is with commercial explosive ammonium ladder, ammonium oil, three kinds of different explosives of emulsification, it can be single or the combined type powder charge, under the detonating of electricity or on-electric detonator, make the junked tire that is placed in the destructor under the effect of high energy, it is broken to disintegrate rapidly.Its feature: the homemade civil explosive of low explosion velocity in 1. using.2. charge constitution is a blast with linear charges.3. each junked tire of unit consumption is generally 0.5～3 in 20～300 grams, detonator.4. product has products such as 1～2 millimeter thick rubber powder, the thin rubber powder of 0～60 purpose, 60～100 purpose fine glue powders and nylon, steel wire.5. energy-conservation economize on electricity.
The present invention prepares the technology and the principal character of rubber powder:
1, technology
Junked tire preliminary treatment → bundling → powder charge and lay that detonator → detonate → tire disintegrates, pulverizing → screening → freezing or ozone treatment → mechanical crushing → magnetic separation → classification → screening → check product (rubber powder, nylon, steel wire)
2, principal character
1. 4. low, the remarkable in economical benefits of simple, convenient, safe, practical 2. energy-conservation, the efficient height that economizes on electricity 3. of technology, cost can realize the resource regeneration harmless treatment 5. floor space is few
