Abstract

The invention relates to a reaction kettle that processes the waste tyre and waste plastics by cracking, comprising a reaction kettle cylinder; wherein, a hot air layer is arranged outside the reaction kettle cylinder and is communicated with a hot air inlet and a hot air outlet. A feed opening is arranged above the reaction kettle while a discharge opening is arranged below the reaction kettle. An air outlet for the gas produced during reaction is arranged on the sidewall of the reaction kettle cylinder, and is connected with a dewaxing device. An alkali material injection port is arranged at the side of the feed opening above the reaction kettle cylinder. The alkali powder or lye can be added into the reaction kettle intracavity through the alkali material injection port to remove the acid gas produced and thus prolonging the service life of the device. The gas after reaction is dewaxed by the dewaxing device when removed, which enables the wax to be completely converted into fuel oil and the yield of the product is improved greatly.

Description

Utilize fragmentation pattern to handle the reactor of junked tire and waste or used plastics
Technical field
The present invention relates to a kind of reactor, particularly a kind of reactor that utilizes fragmentation pattern to handle junked tire and waste or used plastics.
Background technology
Along with developing of automobile industry, also increasing to the demand of rubber items such as tire, also can produce a large amount of junked tires simultaneously.Inevitably can cause environmental pollution when handling automobile junked tire and waste or used plastics.Statistics according to relevant data, worldwide produce 1,000 ten thousand tons of junked tires at present every year approximately, the accumulation of a large amount of junked tires is land occupation not only, contaminate environment, the harm residents ' health, and very easily cause fire, thus cause the huge waste of resource, be a kind of endanger increasing " black pollution ".In order to address the above problem, roughly can be divided into 4 kinds, i.e. accumulation or landfill, burning, biological degradation, recycling to the common processing mode of junked tire.4 kinds of schemes cut both ways, and from the environment protection and the angle that economizes on resources, recycling is optimal method, and this method utilizes type of heating to carry out, and is automobile junked tire catalytic pyrolysis under low-temperature condition is finally obtained corresponding product.In heat treated process, the place that reactor takes place for reaction.Existing reactor structure is that a cylindrical shell that is supported on the frame is arranged, and with the board making of carbon steel material, reactor is divided into inside and outside two-layer the reactor cylindrical shell usually, and internal layer is mainly used in deposits material, is the main place that reaction takes place.Skin is mainly used in the circulation of warm air, heats for the material in a whole set of reactor as heat-transfer medium with warm air.Warm air is by constantly being delivered to temperature in the middle of the internal layer outer field flow.In heat transfer process, outer field warm air does not contact with the raw material of internal layer.For the material in the reactor can be delivered from godown under the effect of gravity in direct landing, the entire reaction still is obliquely installed, and an end of reactor cylindrical shell has opening for feed to be positioned at the top, and the other end is that discharge port is positioned at the below.But opening for feed and discharge port place are equipped with the door of switch.Discharge port is closed during charging, closes simultaneously for two during reacting by heating, opens the discharge port discharge after the reaction.Be provided with on the side of reactor cylindrical shell and the outlet of the generated reactive gas of its intracavity inter-connection, reactant gases forms various oil products by other processing steps after getting rid of again.The reactor of present this structure difference according to material in cracking process can produce a large amount of sour gas.Because sour gas has very high corrodibility and very easily water-soluble.In process of production, in case sour gas combine with moisture content, will corrosion reaction equipment, this not only causes a large amount of financial losses, and the safety of production process has been produced hidden danger.In the process of cracking waste or used plastics, also can produce a large amount of wax, in a single day produce the productive rate that this cracking wax just can reduce oil product greatly in the production, and can cause danger by blocking pipeline.
Summary of the invention
The purpose of this invention is to provide and a kind ofly have the dewaxing function and improve the oil product productive rate, have the fragmentation pattern that utilizes of removing sour gas composition function and improving service life of equipment and handle the reactor of junked tire and waste or used plastics, overcome the deficiencies in the prior art.
The reactor that utilizes fragmentation pattern to handle junked tire and waste or used plastics of the present invention, it comprises reactor cylindrical shell 1, be provided with hot air layer 2 in the outside of reactor cylindrical shell 1, link to each other with hot air layer 2 and to be connected with hot-air inlets 3 and hot air outlet 7, above reactor cylindrical shell 1, be provided with opening for feed 6, the below is provided with discharge port 4, the sidewall of reactor cylindrical shell 1 is provided with the generated reactive gas outlet 8 with reactor cylindrical shell 1 intracavity inter-connection, it is characterized in that: be connected to dewaxing device 14 in the described generated reactive gas outlet 8, the side of the top opening for feed 6 of reactor cylindrical shell 1 is provided with alkali material entrance 5.
The reactor that utilizes fragmentation pattern to handle junked tire and waste or used plastics of the present invention, the structure of wherein said dewaxing device 14 is that a solid catalyst housing 11 is arranged, the ingress of solid catalyst housing 11 is provided with filter screen 12 and joins by pipeline 10 and generated reactive gas outlet 8, the exit of solid catalyst housing 11 is provided with filter screen 17 and joins with pipeline 15, and the solid catalyst in the solid catalyst housing 11 is a molecular sieve 13.
The reactor that utilizes fragmentation pattern to handle junked tire and waste or used plastics of the present invention is equipped with valve 9 on the wherein said pipeline 10, and valve 16 is housed on the pipeline 15.
The reactor that utilizes fragmentation pattern to handle junked tire and waste or used plastics of the present invention, owing in generated reactive gas outlet 8, be connected to dewaxing device 14, the side of the top opening for feed 6 of reactor cylindrical shell 1 is provided with alkali material entrance 5, in fill process, can add ground caustic or alkali lye to remove the sour gas that is produced to the reactor inner chamber, prolong service life of equipment by alkali material entrance 5; Reacted gas carries out dewaxing treatment through dewaxing device 14 in exclusion process, make wax change into oil fuel fully, has improved the productive rate of product greatly.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Embodiment
