Ultrahigh-calorific-value garbage split-range drying pyrolysis gasification internal combustion power generation technology

Abstract

The invention provides a resource utilization system for treating urban ultrahigh-calorific-value garbage. The system comprises an ultrahigh-calorific-value garbage pretreatment system, an ultrahigh-calorific-value garbage drying system, a pyrolyzer system, a gasification system, a purification system, a gas storage tank and an internal combustion engine power generation system. The garbage pretreatment drying device is used for pretreating the ultrahigh-calorific-value garbage. The drying device is used for reducing moisture in the ultrahigh-calorific-value garbage, and is connected with thepyrolysis and gasification system devices for pyrolysis and gasification gas production of the ultrahigh-calorific-value garbage. The pyrolysis and gasification system device is connected with the combustible gas purification system device and is used for purifying combustible gas. The purification system is connected with the gas storage device and used for combustible gas storage and combustiblegas buffering. The gas storage device is connected with the internal combustion engine power generation system and used for combustible gas resource power generation. The technology provided by the invention is good in environmental benefit, good in harmless effect and high in practicability, and energy recycling of the garbage is achieved.

Description

technical field [0001] The patent of the present invention provides a system for treating ultra-high calorific value waste, especially suitable for pyrolysis and gasification of ultra-high calorific value waste after ultra-high pressure dry-wet separation and mechanical treatment. Background technique [0002] The main technical means of domestic waste disposal are landfill and waste incineration. With the development of society and the acceleration of urban processes, people's material life is becoming more and more abundant, and the output of daily life garbage is increasing. Environmental issues have become an important factor affecting social development. At present, the problem of low efficiency of urban domestic waste recycling in my country is also limited by land resources and ecological environment. Although the construction cost of landfill treatment is low, ranging from 150,000 yuan / ton to 400,000 yuan / ton, but Its processing capacity is far from being able to sol...

Problems solved by technology

At present, the problem of low efficiency of urban domestic waste recycling in my country is also limited by land resources and ecological environment. Although the construction cost of landfill treatment is low, ranging from 150,000 yuan / ton to 400,000 yuan / ton, but Its processing capacity is far from being able to solve the speed of garbage generated by the current social development. At the same time, water pollution caused by leachate generated after landfill, air pollution caused by landfill gas generated by the decomposition of organic matter in garbage, and garbage The soil pollution caused by a large amount of glass, batteries and plastics entering the soil has not adapted to the trend of today's social development and has been gradually eliminated

The use of incineration treatment speeds up the speed of waste disposal, but the huge flue gas treatment equipment brought about by the excess air volume, as well as the infrastructure investment brought about by ash transportation and treatment, leachate treatment and other links, and the problem of dioxins generated during the combustion process It is an internationally recognized highly toxic substance, which has fatal hazards and serious effects on the human body and the surrounding environment.
