Abstract
A process for preparing the acetylene carbon black from used and rejected plastics and tyre includes thermodecomposing at 400-600 deg.C, thermodecomposing again in the optimally designed reactor with DC arc plasma generator, and collecting the product by cyclone separator.
Description
One, technical field
The present invention utilizes plastic waste, damaged tire to prepare the method for Shawinigan black and the category that technology belongs to chemical production technical field.
Two, technical background
Plastic waste, damaged tire are the environmentally harmful wastes of a class of following the human modern life to produce.Because human lives and social civilization are more and more serious to the degree of dependence of plastics, as disposable plastic bag, agricultural mulching, disposable transfusion device, various casing, medical needle tubing etc., thereby the quantity of demand is in quick increase.Yet in a single day these materials become waste and enter environment and can cause " white pollution ", and entering soil can influence crop yield, and revealing to put in the external world to influence environmental beauty.If the waste plastic after medical such as also can diseases inducedly propagate at problem; Damaged tire is the another kind of waste of modern civilization life.The swift and violent increase of various Motor vehicles causes the rapid rising of damaged tire quantity, thereby environment is caused having a strong impact on of what is called " black pollution ".This two class " white " and " black " waste are carried out harmlessness disposing and can recycling be the human very urgent problem of feeling in the recent period.The fuel that pyrolysis liquefaction produced of plastic waste, damaged tire is said to a certain extent at present, can promote its utility value, but be to be solved, thereby only liquid do not utilized institute's potential useful matter in the liquefaction process is farthest developed by simple combustion system because of directly still having many problems to have as the fuel of Motor vehicles.Therefore, understand in this sense, directly use as conventional fuel its potential value is not made full use of, belong to extensive style and utilize mode.The present invention is based on this situation, develop two-stage method technology and handle, these refuses can be changed into a kind of important substance---the Shawinigan black of chemical field widespread demand through special device.
At present the operational path of Shawinigan black be earlier with coal by being transformed into carbide of calcium with lime calcining, hydrolysis becomes acetylene then, carries out pyrolysis again.Its production process route comparative maturity, but since environmental pollution is serious and coal resource be difficult to regeneration, can be exhausted, seek alternative materials and new production route and seem very necessary.The present invention is to be raw material with plastic waste, damaged tire, at first obtains higher liquid or the gas of productive rate by conventional fast pyrogenation, then the product reactor through optimization design under plasma condition that obtains is carried out pyrolysis once more, can obtain Shawinigan black.
Three, summary of the invention:
The present invention is difficult to digest, be difficult to a kind of method and technology that promotes its utility value that the efficient situation of utilizing is researched and developed in view of a large amount of waste or used plastics, the damaged tire that produce in the environment.Can obtain carbon dust, and the widely used Shawinigan black in fields such as manufacturing of electronic component by this technology and technology in battery, high-carbon black pigment, printing, duplicating and Laser Printing.Advantage is to greatest extent these refuses to have been carried out recycling; solved in the protection environmental process stubborn problem has been compared in these waste treatment; overcome the limited coal resource that causes by coal system Shawinigan black and reduced problem, and obtained the high value-added product Shawinigan black.
The present invention utilizes plastic waste, damaged tire prepares the method for Shawinigan black, it is characterized in that it being with various waste or used plastics, damaged tire is a raw material, adopt the two-stage method processing treatment, its technological process is: with various waste or used plastics, damaged tire, in temperature is 400-600 ℃, rare gas element is to send into fluidized-bed reactor under the condition of carrier gas, carry out first section fast pyrogenation, gas-phase product in reactor the residence time less than 0.6 minute, then the gas-phase product that pyrolysis is obtained is directly sent into the direct current-arc plasma producer by carrier gas, second section graphiote reactor through optimization design carries out pyrolysis again, the solid material that the collection pyrolysis obtains is a Shawinigan black, its processing parameter is: working current is 110～190A, and voltage is 240～340V, and the flow of argon gas is 0.5～2m
3/ h, main hydrogen flow is 0.5～2.0m
3/ h, secondary hydrogen flow is 0.2～2.0m
3/ h, input speed is 0.6～4kg/h, and reactor inside diameter is 40～70mm, and length is 1500～1800mm.
Above-mentioned a kind of method of utilizing plastic waste, damaged tire to prepare Shawinigan black, it is characterized in that described raw material is the mixture of damaged tire and plastic waste or the single thing of damaged tire or plastic waste, the gas-phase product that described pyrolysis obtains also can put together after cooling becomes liquid collecting and carry out second section pyrolysis again.
Above-mentioned a kind of method of utilizing plastic waste, damaged tire to prepare Shawinigan black is characterized in that described damaged tire and plastic waste size range are greater than 40 orders or less than 0.44mm.
The advantage that the present invention utilizes plastic waste, damaged tire to prepare the method for Shawinigan black is: the generation and the decomposition of acetylene are carried out synchronously; shortened traditional operational path; technical scheme is advanced unique; raw material is a large amount of damaged tire, plastic waste waste; the source is abundant; acquisition cost is cheap, belong to the project that field of environment protection is encouraged and supported, thereby this technology has wide market application prospect.
