Abstract

With the development of urbanization in China, the problem of garbage disposal has become increasingly serious. Among the existing waste treatment technologies, pyrolysis is an emerging treatment technology, which has obvious advantages in terms of reduction and secondary pollution. It has good development prospects. This article first compares the advantages and disadvantages of various existing waste treatment technologies, and proposes an organization method that combines thermogravimetric analysis, kinetic analysis, tube furnace experiments, and domestic waste pyrolysis and low-calorie heat the decomposed gases burn together. Urban garbage is one of the main pollution sources of modern urban environmental pollution in the world. Developed countries attach great importance to the study of geological disposal of solid waste. This area is a hot issue for environmental engineering workers. At present, a large number of cities have formed a serious situation of urban solid waste accumulation. The quantity of China’s urban solid waste has grown rapidly. How to deal with huge urban garbage will be a major issue related to economic development, water resources and environmental protection. This article also researches the TG-FTIR combined thermogravimetric analysis of domestic waste, the biomass pyrolysis process was observed to be similar. The second region of the weight conversion process of the energy conversion and utilization system can be described by the first-order chemical kinetic reaction of F1, and the third region can be described by the third stage of D3. Diffusion reaction to transport is described. The activation energy and pyrolysis rate of each component in the flue gas atmosphere are higher than those in the N2 atmosphere. Finally, through research on the thermal weightlessness process and gas production process of waste, a detailed description of the recycling process of waste pyrolysis and the pyrolysis gas combustion integrated process is provided, which can act as the basis for future research on the subject.
