Carbonized city garbage fuel block preparation method and its dedicated apparatus

Abstract

The invention discloses a method for preparing fuel brick with pyrolysis and taking city waste as raw material, and it aslo relates to special device- pyrolysis retort. The invention is to thermal decompose the organic matter in city waste, produce anoxic uindirect heating condition through proper engineering technology during pyrolysis, control heating temperature, heating speed and thermal insulating time to make the organic matter in city waste form into solid carbon, and converse carbonized city waste into fuel brick.

Description

technical field [0001] The present invention relates to a method for producing fuel blocks using pyrolysis technology and urban waste as a raw material, and also relates to special equipment using the above-mentioned method—a pyrolysis carbonization furnace. Background technique [0002] Where there are human beings engaged in production and living, there will be waste; where there is waste, there will be environmental problems. With the continuous development of human society, social productivity has increased rapidly, and the process of industrialization and urbanization has gradually accelerated. Today, many countries and regions around the world have entered a period of highly developed industrialization and urbanization. Accompanying this is that the types and quantities of urban waste output are increasing rapidly, and the hazards of urban waste are gradually becoming prominent. [0003] my country currently has 668 cities with a population of more than 300,000. The...

Problems solved by technology

[0007] 1. The main weaknesses of incineration treatment technology are: large construction scale, long construction period; complex equipment technology, difficult operation; large investment amount, high operating cost; only suitable for the treatment of combustible municipal waste with high calorific value The scope of application is small; especially the severe secondary pollution generated during the incineration process, it is difficult to treat and discharge up to the standard

[0008] 2. The main disadvantages of sanitary landfill technology are: large area occupied, long time occupied, low probability of land restoration and reuse; improper engineering treatment can easily cause serious pollution to land, water, and atmosphere, and site selection is difficult; The utilization rate of waste resources is extremely low

[0009] 3. The main weaknesses of composting treatment technology are: huge composting equipment, difficult production and manufacturing; complex process technology, strict operation control requirements; long construction period, large investment amount; only suitable for the treatment of degradable organic matter in urban waste , the scope of adaptation is small

However, in such a complex and continuous chemical reaction process, due to the interaction or interaction of various factors such as organic species, heating temperature, heating rate, holding time, and reactor form, the actual reaction process does not have a very obvious stage. Sex, many reactions are carried out in mutual crossing
