Efficient and safe waste pyrolysis gasifier

Abstract

A high-efficiency and safe garbage pyrolysis gasification furnace consists of a rotary furnace body, a furnace base, a ball turntable, a furnace cover, a high-temperature superconducting heat exchanger, a gas collecting pipe, a liquid sealing sleeve, a conical heat exchanger, an annular heater, and an inlet It is composed of feeder, superconducting waste heat recovery device and driving device. It is characterized in that the closed furnace body is connected with the upper raceway disc of the ball turntable below, the furnace base is connected with the lower raceway disc of the ball turntable above, the inner circle edge of the raceway disc is connected with the conical heat exchanger, and several high-temperature ultra- The heat conduction exchanger is assembled on the conical heat exchanger, and the annular heater uses the self-produced gas of the cracking furnace to heat the evaporation section of the high-temperature superconducting heat exchanger, and the high-temperature radiant heat generated is quickly transferred to the furnace through the high-temperature superconducting heat exchanger The rotating garbage completes the safe and efficient pyrolysis and gasification of garbage in a closed anaerobic state. The cracking furnace has a balanced furnace temperature and excellent sealing performance, which effectively solves the defects of bonding, coking, high energy consumption, unsafety, and low gas production efficiency caused by local overheating of garbage in the furnace, and shields the harmful substances released by the cracking products from affecting the environment. Pollution, curbed the generation of dioxin, social and economic benefits are obvious.

Description

Technical field: [0001] The invention relates to a pyrolysis and gasification device for domestic garbage and organic matter, in particular to a low energy consumption, pollution-free, efficient and safe garbage pyrolysis gasifier. Background technique [0002] With the progress of human civilization and the growth of population, the output of urban domestic waste is increasing day by day, the composition of waste is becoming more and more complex, and the number of harmful ingredients is increasing day by day. Traditional landfilling wastes land and destroys groundwater sources and will withdraw from the stage of history. At present, the incinerators used in various places to incinerate garbage have caused serious environmental pollution, which has caused public opposition. Incineration of garbage emits a large amount of smoke, harmful substances, acid gases, unburned waste, heavy metals and trace organic compounds, etc., followed by a large amount of carcinogenic dioxins....

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
