Introduction of Haiqi Waste Pyrolysis Gasification Treatment Technology
The waste pyrolysis technology can effectively overcome the problem of tail gas pollution caused by waste incineration while realizing the harmlessness, reduction and resource utilization of waste, and thus becomes an emerging waste disposal technology with great development prospects. The waste pyrolysis gasification technology is also called the third generation technology of waste disposal.
The whole process is mainly composed of five subsystems: garbage processing feeding system, garbage pyrolysis gasification system, waste heat boiler system, exhaust gas purification system, generator set system.
I.Garbage Pyrolysis Gasification Technology Principle
II.Principle of Pyrolysis and Gasification
In the process of pyrolysis, water vapor, free oxygen or combined oxygen reacts with carbon in the fuel to form a combustible gas. The process of waste pyrolysis gasification is complicated, and the conditions of pyrolysis gasification reaction are also different, but all the processes of pyrolysis gasification reaction basically include the processes of drying, pyrolysis, oxidation and reduction of biomass.
