Efficient and safe garbage cracking gasification furnace

Abstract

An efficient and safe garbage cracking gasification furnace is composed of a rotary furnace body, a furnace base, a ball rotating disc, a furnace cover, high-temperature superconducting heat exchangers, a gas collecting pipe, a liquid sealing sleeve, a cone heat exchanger, an annular heater, a feeding machine, a superconducting waste heat recoverer and a driving device. The gasification furnace ischaracterized in that the closed furnace body is connected with an upper rollaway disc of the ball rotating disc below the furnace body; the furnace base is connected with a lower rollaway disc of the ball rotating disc on the furnace base; the inner circle edge of the rollaway disc is connected with the cone heat exchanger; the multiple high-temperature superconducting heat exchangers are assembled on the cone heat exchanger, the annular heater heats evaporation sections of the high-temperature superconducting heat exchangers through gas generated by a cracking furnace, generated high-temperature radiant heat is rapidly conducted to garbage rotating in the furnace through the high-temperature superconducting heat exchangers, and safe and efficient cracking and gasification of the garbagein a closed oxygen-free state are completed. The furnace is balanced in furnace temperature and excellent in sealing performance, effectively overcomes the defects of bonding and coking formed by local overheating of garbage in the furnace, high energy consumption, unsafety, low gas production efficiency and the like, shields environmental pollution caused by harmful substances released by cracking substances, prevents generation of dioxins, and is obvious in social benefit and economic benefit.

Description

Technical field: [0001] The invention relates to a pyrolysis and gasification device for domestic garbage and organic matter, in particular to a garbage pyrolysis and gasification furnace with low energy consumption, no pollution, high efficiency and safety. Background technique [0002] With the progress of human civilization and population growth, the output of municipal solid waste is increasing, the composition of waste is becoming more and more complex, and the harmful components are increasing. Traditional landfill waste wastes land and destroys groundwater sources will withdraw from the stage of history. The serious environmental pollution caused by the incinerators used in various places to burn garbage has caused public opposition. Incineration of garbage emits a large amount of smoke and dust, harmful substances, acid gases, unburned waste, heavy metals and trace organic compounds, etc., along with a large amount of carcinogenic dioxins. At the same time, incineration...

AI Technical Summary

Problems solved by technology

[0006] In order to prevent waste carbonization, coking and air leakage accidents due to local overheating of the cracking furnace, foreign garbage cracking equipment strictly screens and classifies the garbage entering the cracking furnace in advance and installs multi-layer sealing measures. The entire garbage processing equipment is bulky and expensive. , which is unavailable for countries with underdeveloped economies and waste sorting and screening not yet implemented
