Abstract

The invention relates to a large-scale waste gasification treatment and energy recycling system which comprises a water vapor low-temperature pyrolysis system, an entrained flow gasification system, a waste heat recovery system, a fuel gas purifying system and a fuel gas generating system. In the system disclosed by the invention, waste is transformed into an odorless and aseptic substance containing a small amount of inherent moisture by a low-temperature water vapor cracking reaction kettle; then the substance enters an entrained flow gasification furnace to be pyrolyzed and gasified into combustible gas; the combustible gas is purified by the fuel gas purifying system and is sent into a fuel gas generator to generate electricity; after gasification, slags and soil sediments separated from raw refuse are sent to brick making equipment to produce building materials; and wastewater generated in the process of purifying fuel gas enters a wastewater pond to be further treated. Due to the adoption of the system disclosed by the invention, the waste can be effectively treated, so that the waste treatment is developed towards the large-scale recycling and comprehensive utilization direction from the single treatment technology and the regeneration utilization of recyclable energy is furthest realized.

Description

technical field [0001] The invention relates to the technical field of environmental protection and renewable energy. Specifically, the invention relates to a large-scale garbage gasification treatment and energy recycling system. Background technique [0002] With the progress of human society, the output of garbage is also increasing year by year. At present, the annual output of garbage in the world is 490 million tons, and the growth rate is 8.42%. The annual output of urban waste in China is 150 million tons, and it is growing at a growth rate of 10%, while the cumulative stock of waste is 7 billion tons. The waste disposal pressure in China and the world is extremely high. [0003] The annual output, growth rate and stockpiles of waste do not match the existing level of waste treatment, especially in developing countries. Most of the existing waste disposal methods are distributed and small-scale, and the waste disposal technology is not yet mature. Composting and ...
