All-closed zero-emission household refuse energy regeneration and comprehensive utilization production process

Abstract

The invention discloses an all-closed zero-emission household refuse energy regeneration and comprehensive utilization production process. The production process specifically comprises the steps of refuse classification, pretreatment and inert substance treatment for brick making, organic matter pyrolysis, reforming and synthesis into fuel oil, acid gas absorption and fertilizer synthesis, wastewater treatment and reclaimed water recycle. The production process is used for treating organic matter waste and the like, classification is not needed, the environmental problem caused by urban refuse can be solved, energy is effectively reproduced, slow-release fertilizer returned to land is produced, household refuse is subjected to pyrolysis, reforming and synthesis to produce effective slow-release fertilizer, clean fuel and the like, inert residues are subjected to thermal modification to be used for making building bricks, and an effective carbon cycle is achieved. In the whole running process, energy consumption is reasonable, secondary pollution is avoided, the products are controllable and high in output value, high-purity fuel can be effectively produced, it is guaranteed that whole production is free of emission, and a closed operating environment enables the process to be safe without hidden danger.

Description

technical field [0001] The invention relates to a comprehensive treatment process of garbage, in particular to a fully enclosed zero-emission energy regeneration and comprehensive utilization production process of domestic garbage. Background technique [0002] The problem of garbage endangering the environment and energy shortage is one of the important issues that need to be solved in the world today. At present, the garbage treatment technology widely used in the world still has insurmountable problems, which can be described as follows: [0003] 1. Incineration power generation: [0004] On the one hand, the heat generated is used for power generation and heating. On the other hand, the biggest disadvantage is that secondary pollutants, such as dioxin and other harmful gases, are produced during garbage incineration, which pollutes the environment again. At the same time, the initial investment in incineration treatment is large, the incineration related equipment is ea...

AI Technical Summary

Problems solved by technology

Due to the inevitable generation of harmful and polluting substances by the method itself, the complex separation of the generated products, the special treatment of the waste, and the long process cycle, these characteristics determine the limitation and high cost of the biological treatment method, so it has always been Cannot be used as the main means of garbage disposal
