Pyrolysis technology is a new technology for waste treatment developed quickly in recent years. In the early 90s, foreign scientists found that during the process of burning waste, it will produce extremely harmful carcinogens to human-Tetrachlorodibenzo- p-dioxin. Therefore, when the western developed countries study how to avoid producing secondary pollution when burning waste, they spend large sum of money to develop and research new garbage disposal technology. Waste pyrolysis technology is generally recognized by national environmental protection experts, they think this is a new road for waste harmless, reduction and recycling.
A way to pyrolysis waste
It is can bring pollution to burning or landfill waste plastic,rubber and tyre.Pyrolysis technology designed by DOING company can turn waste plastic,waste ruber and waste tyres by pyrolysis. The end product from pyrolysis plant is fuel oil. Fuel oil can use to heavy industries, like cement factory,brick factory, boiler etc.
pyrolysis oil application
1.The theory of pyrolysis technology.
pyrolysis technology and burning are tow totally different process. Incineration is an exothermic process, and pyrolysis technology need to absorb a lot of heat. The main product of incineration are the carbon dioxide and water, pyrolysis technology mainly take advantage of thermal instability of the organic matter in waste, under the condition of the anaerobic or anoxia, let organic produce cracking, after condensation to form a variety of new gas, liquid and solid, extract process of fuel oil, combustible gas.
In one word, the essence of pyrolysis technology is the process by heating the molecular organic molecules, let it crack into many small molecular, which contains many complicated physical and chemical process.
2.The method of pyrolysis technology.
Thermal decomposition process has a different pyrolysis method due to the heating way, the product shape, and the different pyrolysis furnace structure. According to the different pyrolysis temperatures, more than 1000 DHS C called high-temperature pyrolysis, 600-700 DHS C called tepid solution, 600 DHS C hereafter called low temperature pyrolysis. Pyrolysis way has direct heating method and the indirect heating method according to the heating points.
3.The main characteristics of innovation pyrolysis technology.
(1)Combine of direct heating and indirect heating
(2)Set the mixed gas reaction device, make gas sufficient reaction.
(3)Use of advanced dust removal system, solve the waste pyrolysis gas emissions problem.
