Description
Technical field
The present invention relates to a kind of treatment process of waste old, particularly a kind ofly add the harmless treatment process that catalyst pack contains the waste old of steel wire.
Background technology
Present economic develop rapidly along with the whole nation, increasing rubber enters into the every field of national economy, and therefore the rubber recoverable amount in the whole world increases rapidly, and the consequent is the problem that is treated as a needs solution of the waste old in every year.The processing of early stage waste old mainly is the harmless treatment to waste, but along with the notion of green economy proposes, waste old all can be recycled become a whether problem of Sustainable development, the consequent is that waste old is carried out cracking, reclaim carbon black, oil fuel and combustion gas in the waste old, but present treatment process is at first to need to send pyrolyzer to handle in the waste old fragment.Because do not have catalyzer as adding material, its cracking temperature is difficult to control, the carbon black quality is very low.And too high at oil product and fuel gas sulphur content, environment is produced pollution.Have plenty of and adopt the big fragment of the waste old after freezing method will cut to be refrigerated to end temperature, and then the particle of rubber is pulverized, but aforesaid method extremely wastes energy, the energy-conservation Sustainable development that can't realize with the method for bump.
Summary of the invention
The objective of the invention is to solve and handle the existing the problems referred to above of waste old in the prior art, a kind of harmless treatment process that catalyst pack contains the waste old of steel wire that adds is provided, the present invention designs a kind of harmless treatment process that catalyst pack contains the waste old of steel wire that adds, comprise washing waste old, crusher in crushing, it is characterized in that: the interpolation of the waste and old rubber particle after fragmentation catalyzer is contained steel wire send into the pyrolyzer cracking, fuel-air mixture body that produces after the cracking and solid carry out gas-oil separation respectively to be separated with sooty with the steel wire section; Inflammable gas after the gas-oil separation is recycled to the pyrolyzer burning, and fuel cools reclaims.Oil and gas separation method is the cooling fuel-air mixture, and fuel-air mixture is isolated inflammable gas and oil fuel after cooling.Steel wire separates with sooty, and the carbon black that contains the steel wire section is cooled off, and utilizes the separation screening auger that the steel wire section is separated with carbon black then.The steel wire section is cleaned the back and is reclaimed, and carbon black is reclaimed by stirring-granulating behind abrasive dust.With 390 ℃---temperature cracking 25 of 420 ℃---35 minutes, the footpath grain of the waste and old rubber particle of crusher in crushing is 20 to waste and old rubber particle in pyrolyzer---30 millimeters.It is characterized in that: described catalyzer is SiO

2O
3, Fe
2O
3Mixture.It is characterized in that: SiO
2, Al
2O
3, Fe
2O
3Ratio of mixture be 1: 1: 3.Because the effect of catalyzer: the Oil Recovery rate is more than 46%, and combustible gas reclaims 7%, and the carbon black sulphur content is more than 3%.Advantage of the present invention is that a whole set of treatment process has advantages such as energy consumption is low, safety, environmental protection, non-pollutant discharge.
Description of drawings
Accompanying drawing is a process flow sheet of the present invention,
Below in conjunction with drawings and Examples the present invention is elaborated.
Embodiment
At first the waste old that reclaims is washed, be mingled in wherein rubbish to remove some, send crusher in crushing with waste old then, generally waste old need be broken into the footpath grain is 20---30 millimeter-sized particles, after fragmentation, note the bulk loopback crusher in crushing again of complete fragmentation at any time, waste and old rubber particle after will pulverizing then (adds catalyzer, for pressing 1: 1: 3 blended SiO
2, Al
2O
3, Fe
