Domestic garbage fluidized bed anaerobic splitting decomposition device

Abstract

The invention discloses a domestic garbage fluidized bed anaerobic splitting decomposition device. A splitting decomposition feeder is positioned at one end of the splitting decomposition device; a deoxidizer is connected with the splitting decomposition feeder; an anti-explosion pressure relief sealing device is mounted on the top of the deoxidizer; a splitting decomposition furnace is positioned on the lower side of the deoxidizer; a furnace wall heater is mounted on the upper side of the splitting decomposition furnace; a reformer is mounted at the upper end of the splitting decomposition furnace; a heating rod is arranged on the lower side of the splitting decomposition furnace; a residue hole is connected with the splitting decomposition furnace; a classification cyclone separator is connected with the reformer; an exhaust hole is connected with the classification cyclone separator through a pressure valve; a high-temperature fan is connected with the heating rod. The domestic garbage fluidized bed anaerobic splitting decomposition device is a novel fluidized bed anaerobic splitting decomposition system for achieving harmless resource treatment on unclassified garbage, can treat continuously and is simple to operate, high in automation degree, low in unit energy consumption and free of secondary pollutant generation or discharge, the system is optimized, and product splitting decomposition gas is high in thermal value, very low in tar content, uniform in carbon structure and high in activity.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a fluidized bed anaerobic cracking device for domestic garbage. Background technique [0002] In recent years, the annual growth rate of municipal solid waste has been 5%-8%, and the annual growth rate of waste in a few large cities has reached 8%-10%. The per capita daily waste production has exceeded 1 kg, which is close to the level of moderately developed industrial countries. The amount of urban waste generated in my country has shown a sharp increase, and the trend of growth is getting faster and faster. The large amount of domestic waste and the imperfection of treatment technology have caused increasingly severe negative impacts on the country's economic development, people's quality of life and the natural environment. While fully aware of this development bottleneck, countries around the world are actively concentrating on the development of effective technologies that...

Problems solved by technology

Partial pyrolysis process, under the premise that the garbage is not sorted, it is difficult to control the combustion conditions and the working state is unstable

Due to the unevenness of waste and the change of composition, the process conditions such as furnace temperature change greatly, and the fluctuation of working conditions makes the operation very difficult.

The gas produced by partial cracking or gasification has a very low calorific value, making it difficult to directly use gas engines to generate electricity, and the widely used steam turbines are not efficient in generating electricity, which limits the level of recycling of waste disposal resources

Through condensation dehydration and spraying, although some pollutants are eliminated and the corrosion and emissions in the later stage are reduced, the calorific value of the gas has not been significantly improved
