Abstract
An automobile tire recovery processing method mainly comprises the steps of: crushing a decontaminated automobile tire into strips with end surface area of less than 50mm<2>, carrying out thermal pyrolysis on the strip-shaped rubber in a special thermal pyrolyzer at the temperature of 450-500 DEG C under the state of negative pressure of 0.05-0.07MPa for 10-15 minutes, carrying out gas and oil recovery and separation through a condenser, wherein the primary fuel adopted for pyrolysis is coal, after combustible gas generated in continuous running of the pyrolyzer can entirely return back to the bottom of the pyrolyzer as a secondary energy resource for pyrolysis and heating so as to replace a part of primary energy resource; and removing metal parts by adopting an electromagnet to obtain carbon black of 700-900 meshes. The automobile tire recovery processing method has the advantages that the process flow is high, the effluent oil quality and oil extraction rate are high, the calorific value of the recovered industrial fuel oil is far higher than that of natural gas, liquefied gas and other fuels, so that the recovered industrial fuel oil is extremely good high-performance liquid fuel, and the automobile tire recovery processing method is the most environment-friendly processing mode with highest economic benefits.
Description
Technical field
The present invention relates to rubber and reclaim the field, particularly a kind of doughnut recovery and treatment method.
Background technology
Rubber has been widely used in the every field of national economy as macromolecular material, and junked tire quantity is big, and intractability is big, and depositing or deal with improperly all can serious environment pollution, and the reason of junked tire has become very urgent environmental problem and social concern.At present junked tire comprehensive utilization scope of the enterprise is generally less, produces lack of standardizationly, and ubiquity the energy consumption height, polluted the problem of weight, has restricted the development of enterprise and whole industry.
Summary of the invention
The objective of the invention is for the useful matter in the abundant recovery junked tire, energy-conserving and environment-protective, the spy provides a kind of doughnut recovery and treatment method.
The invention provides a kind of doughnut recovery and treatment method, it is characterized in that: described doughnut recovery and treatment method, mainly comprise after the doughnut decontamination processing, be broken into strip, face area is less than 50 square millimeters, strip rubber carries out thermo-cracking in special-purpose pyrocrack furnace, temperature is 450-500 ℃, under the negative pressure state of 0.05-0.07 megapascal (MPa), carry out thermo-cracking, time 10-15 minute, realize gas by condenser, recovery of oil separates, and the primary fuel that cracking is adopted is coal, after cracker turns round continuously, the inflammable gas that produces can all return furnace bottom as the secondary energy of cracking heating, replaces primary energy source amount 30-40%, adopts electro-magnet, remove the metal part, carbon black 700-900 order.
Described special-purpose pyrocrack furnace structure is split type barrel-like structure, and the magnet switching electric control is adopted in sealing and unlatching, adds the thermal recovery electric heater unit.
Advantage of the present invention:
Doughnut recovery and treatment method of the present invention, technical process is simple, goes out oil quality and oil yield height, and the industrial fuel oil that is recovered to, its calorific value are a kind of fabulous liquid high performance fuels far above Sweet natural gas, liquefied gas and other fuel.Described doughnut recovery and treatment method is to handle the also processing mode of tool economic benefit of the environmental protection of junked tire.
