Design And Experimental Study Of Continuous Pyrolysis Equipment For Waste Rubber

With the rapid development of economy and the continuous innovation of science and technology,rubber products industry has been booming.At the same time,waste rubber as a new class of solid waste poses a serious threat to the ecological environment.In the case of a serious shortage of rubber resources in China,how to achieve the high value of the use of waste rubber is essential.After decades of exploration,cracking technology is recognized as one of the best ways to deal with the waste rubber problems.Waste rubber cracking technology not only to achieve the zero emissions of pollutants,but also to achieve cracking gas,fuel oil,carbon black and other high-value resources recycling.It can not only realize the solid waste resourceful treatment,but also produce huge economic and social benefits.In this paper,by ansylysis the development situation of waste rubber pyrolysis technology,compare the advantages and disadvantages of different pyrolysis process,put forward a new type of heat source to provide way-electromagnetic pyrolysis.Designed a stirring type continuous electromagnetic pyrolysis device for waste rubber.The pyrolysis equipment use the of twin-screw structure for material push,with a single screw discharge system,can achieve the continuous cracking of waste rubber;The interlocking of the twin screws also solves the problem of high viscosity clogging of the molten state material;The use of electromagnetic induction heating characteristics,shorten the temperature rise time,achieved the precise control of the temperature,and improved the production efficiency of equipment.Based on the principle of electromagnetic induction heating and the flow characteristics of rubber melt,the cavity structure and spiral structure of the pyrolysis equipment were designed reasonably.Based on the coupling calculation between maxweell software and workbench software,the eddy current loss and the temperature rise distribution are analyzed.Through the analysis,the feasibility of the electromagnetic induction heating technology as a pyrolysis heat source is verified,which can provide a stable and reliable temperature for the pyrolysis of waste rubber.By changing the parameters of the equipment,the different electromagnetic field distribution cloud and temperature distribution are obtained.Consider that arranged the coil closely,appropriate to reduce the wall thickness of pyrolysis chamber,reducing the distance between the coil and the pyrolysis chamber,can obtain better heating effect.Several experiments were carried out by adjusting the operating parameters of the process.Comprehensive analysis of the experimental data,determination the pyrolysis products,compared with the rubber cracking situation,obtained the best cracking of waste rubber temperature and energy consumption.The experimental results show that the waste rubber electromagnetic cracking equipment in this project has a large amount of processing capacity and can be produced continuously.It has the advantages of high speed,high efficiency,stable operation,good cracking effect,low cost,energy saving and environmental protection.The related design and conclusions provide a reference for the further study of the continuous pyrolysis equipment...
