More than 20 million tons of scrap tires are generated each year globally. This constitute great threat to the living environment of people, and therefore, scrap tires are called black garbage. However nothing in the world is really garbage, and so called garbage is nothing but an useful resource put in a wrong place.
Doublestar Environmental Protection Company, hereafter named as Doublestar, has developed a production line fox comprehensive recycling of scrap tires.
The production line for recycling scrap tires by smart pyrolysis consists of nine modules.
After being broken by a double-axis shredder, the scrap tires are made into blocks of average size of around 30mm. Then they are transported into the pyrolysis module. Doublestar divides the process of decomposing into three intervals of different temperatures, and this works better than that of a single part.
---The firstthermal interval is used to raise the temperature, the purpose of this is tofacilitate the decomposition of plasticizers and rubber accelerators of lowboiling point.
---The secondinterval is used for decomposing. This is to break and decomposing long chainmolecules of natural rubber and synthetic rubber.
---The thirdinterval is used for carbonization. In this stage, volatile materials of smallmolecules with branches on the surface and within the carbon black crystalswill be all separated out.
|Fuil Oil||About 40%~45%|
|Carbon Black||About 30%~35%|
|Steel Wire||About 10%~15%|
|Flamable Gas||About 5%~12%|
Products after pyrolysis consist of oil and gas, and solid residual. Oil and gas are then separated into light oil, heavy oil, and non-condensable flammable gas. Temperatures are displayed on the gas distributing units and the oil tanks. This provides basis for automatic operation of the control system.
Light oil and heavy oil are pumped into oil tanks in the storage module through pipelines. Natural gas is only used during the ignition period. Non-condensable flammable gas is put into the flammable gas module. After being treated and purified by flame arresters, purifiers and explosion-proof units, flammable gas will be made to meet the standard of clean energy source, and will be used for the production line itself in the combustion system.
Solid waste residue generated in the process of pyrolysis is first separated by a magnetic separator. The carbon residue without metals is transported to a storage pool for further deep processing of carbon black. The other part, the metal wire is selected by a magnetic pulley and is collected in a wire briquetting module. Then they are mechanically briquetted, packed by mechanic arms and stored.
The smoke and gas produced in the heat energy recycling process enter the gas and smoke purifying module. In the pyrolysis carbon black refining module, carbon black produced through grinding activation modification techniques is mixed, pelletized and dried, and screened to meet N660 general carbon black standard. The carbon black is then packed, stacked through an automatic system and stored.
In all these processes, no waste water, waste gas or waste residue is generated.
In the central control module, scrap tires recycling production line is sensed and monitored by an Internet based technique. The production process is electronically controlled and visually monitored through a smart management system.
