Description

Environmental protection type waste tyre electrical cracking technique and equipment

Technical field

Technology and equipment thereof are reclaimed in the cracking that the present invention relates to a kind of rubber, plastics, relate in particular to damaged tire cracking technology and equipment thereof.

Background technology

We are in the increasing epoch of automobile, and this has brought opportunities and challenges for us undoubtedly, and the arriving of auto age means that junked tire is more and more, and the pollution of black has caused harm to environment, brings pressure to the mankind.Alleviate this problem, comparatively it is desirable at present adopt hot anneal crack to separate method, traditional method is damaged tire piece material to be put into pyrolyzer carry out carbonization decomposition, therefrom reclaim oil fuel, combustible gas and carbon black, but want mostly earlier the annular steel wire in the damaged tire to be pulled out, again damaged tire is cut into piece, carrying out hot anneal crack in the input pyrolyzer separates, processing link is many, and Production Flow Chart is long, and causes secondary pollution easily.Number of patent application is 200610028197.5, open day is on December 06th, 2006, notification number is that the Chinese invention patent application of CN1872953 discloses a kind of " technique for cracking integral scrap tires ", integral scrap tires can be dropped into the disposable combustible gas that is cracked into fast in the cracking still, oil, thick carbon black and steel scrap silk, reduced process procedure, but its cracking still needs 600-800 ℃ hot gas flow heat temperature raising, hot gas flow is by the combustion chambers burn combustible gas, oil produces, this itself just needs to consume a large amount of fuel energies, and because the combustion chamber is independent of outside the cracking still, the heat that burning produces loses bigger in transmittance process, also is unfavorable for save energy, raises the efficiency.

Summary of the invention

The object of the present invention is to provide a kind of damaged tire cracking technology and equipment of environment-friendly and energy-efficient, designed a kind of with electric energy heat the cracking damaged tire technology and use the pyrolyzer of electric energy.

Environmental protection type waste tyre electrical cracking technique disclosed by the invention comprises the following steps:

1, damaged tire carries out the scale removal cleaning before cracking is handled, and does not disintegrate, does not pulverize, wholely directly drops in the pyrolyzer;

2, pyrolyzer adopts the electric energy heat temperature raising;

3, pyrolyzer Nei Wenduda 250-350 ℃ the time, damaged tire cracking, scission reaction time remaining 40-70 minute;

4, the splitting gas of pyrolyzer enters the condenser condenses separation by pipeline, reclaims and obtains blended fuel and combustible gas;

5, the remaining solid materials in pyrolyzer bottom is discharged, and reclaims and obtains carbon black and steel wire.

The cracking apparatus that cracking technology of the present invention uses comprises pyrolyzer, condenser and housing, pyrolyzer is connected by vapor pipe with condenser, the thermopair in the pyrolyzer and housing by cable be connected, electric heater in the pyrolyzer is connected by power control line with housing; Pyrolyzer comprises that mainly body of heater, upper of furnace body have opening for feed, discharge port is arranged at the bottom, adopts the hydraulic pressure opening tightness system, and vapor pipe, safety anti-explosive device, power connector end and thermopair also are housed on the body of heater, the probe of thermopair inserts the body of heater innermost layer, measures temperature in the body of heater; Totally 8 layers from inside to outside of body of heater furnace walls, the innermost layer is an inner bag, the outside of the inner bag extension muscle with the body of heater axially parallel of evenly arranging, hang muscle and be welded on the outside of inner bag, hang on the muscle well heater is housed, the well heater outside is enclosed with one deck insulation quilt, insulation quilt is outer to be fixed by one deck steel mesh, steel mesh is outward one deck warming plate, and warming plate has one deck structural slab outward, and structural slab has one deck stainless steel casing outward.

The product of cracking technology of the present invention is a radix 100 to drop into waste tyre material weight, then can obtain

Blended fuel 35～40 weight %

Thick carbon black 35 weight %

Steel scrap silk 15～20 weight %

Combustible gas 5～10 weight %

Cracking technology of the present invention and number of patent application are that 200610028197.5 the disclosed cracking technology of Chinese invention patent application is compared, overcome and used combustible gas, oil big as the energy consumption that heating source brought, heat energy thermosteresis in conductive process is big, produce three defectives of waste gas, improved the inventive method uses electric energy as heating source, reduced relevant devices such as burner, combustion chamber, smoke exhaust pipe, electrothermal heater directly acts in the pyrolyzer, heat-energy losses is reduced to minimum.Advance also is, pyrolyzer is in operation smokelessly, noiselessness, nothing leakage, no sewage, no waste gas, no waste, is the environment-friendly type equipment of the cyclic utilization of waste.The equipment of this invention is as follows to the record data statistics in energy consumption and reaction times:

Sequence number	Material name	The weight that feeds intake (kg)	Temperature (℃)	Time (hour)	Fuel names	Consumption	The fuel energy consumption cost
								1	Damaged tire	100	250-350	2.4	Liquefied gas	Every bottle of 4 bottles of 13.5kg/	368 yuan
2	Damaged tire	100	250-350	2.1	0# diesel oil	40kg	219 yuan
								3	Damaged tire	100	250-350	1	Electricity	40 degree	40 yuan

From with the identifying recording layer as can be seen, with electric energy as the heating source of cracking technology of the present invention, same units burst size 81% (the 0# diesel oil /) that can cut down the consumption of energy; The time shortening is 47.6% (0# diesel oil /), and the product after the cracking detects by an unaided eye and can see obviously that the steel scrap silk is better with the separation degree of thick carbon black.

The pyrolyzer that cracking technology of the present invention uses aims at this environmental protection type waste tyre electrical cracking technique design; be total to layer from inside to outside; pass through insulation quilt; insulating protecting plate can effectively reduce heat-energy losses; the more efficiently heat energy that utilizes; make damaged tire can be in the shorter time cracking rapidly; thermocouple probe is inserted into the pyrolyzer innermost layer; be convenient to control cracking temperature, the safety anti-explosive device is housed on the pyrolyzer body of heater, the intravital pressure of control stove; pyrolyzer body of heater upper end has opening for feed; the lower end has discharge port, controls opening for feed with hydraulic efficiency plant; the sealing of discharge port, whole apparatus structure compactness; floor space is little, and is easy to operate.
