High-temperature superconducting non-polluting garbage pyrolysis gasifier

Abstract

A high-temperature superconducting non-polluting garbage pyrolysis gasifier is composed of a furnace cover, a furnace body, a furnace seat, a high-temperature superconducting heat exchanger, a rotating smoke pipe radiator, a heater, a feeder, and a superconducting waste heat recovery device. It is characterized in that the furnace body is equipped with a high-temperature superconducting heat exchanger, and the heater in the furnace seat at the lower part of the furnace body uses the self-produced gas of the cracking furnace to heat the evaporation section of the high-temperature superconducting heat exchanger, and passes the high-temperature radiant heat through the high-temperature superconducting heat exchanger , The rotating flue tube radiator and the round head heat exchanger quickly conduct to the garbage moving on the upper part of the furnace body from different angles, and complete the efficient and rapid pyrolysis and gasification of garbage under high temperature and oxygen deficiency. The pyrolysis furnace has high temperature, balanced furnace temperature, and large gas production, which effectively solves the danger of bonding, bulging, lumping, and coking of garbage caused by local overheating in the furnace, avoids the generation of pyrolysis flue gas, and shields the release of pyrolysis products Harmful substances pollute the environment and prevent the formation of dioxins. The residual gas from cracking is used for power generation, and the solid waste residue is used as raw material for activated carbon chemical industry. The social and economic benefits are obvious.

Description

Technical field: [0001] The invention relates to a domestic garbage gasification device that does not pollute the environment and does not produce toxic substances, in particular to a low-energy consumption, high-efficiency, high-temperature superconducting non-polluting garbage cracking gasifier. Background technique [0002] With the progress of human civilization and the growth of population, the production 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 and have been opposed by the public. Incinerators are used to incinerate garbage, emitting a large amount of smoke, harmful particles, acid gas, unburned waste, heavy m...

Problems solved by technology

[0005] There is no temperature equalization device in the reaction zone of the domestically developed horizontal pyrolysis gasifier, which cannot maintain a relatively balanced high temperature and pressure in the reaction zone. The harmful substances released by the lysates and the pollution and toxicity of dioxins to the environment

In particular, the traditional pyrolysis furnace body has a single-tube single-layer structure, and the heater is located outside the furnace body, and the single-layer furnace body is heated at a high temperature locally. Barbecue, the inhomogeneity of the temperature field along the axial and radial direction of the furnace body not only wastes energy but also leads to extremely uneven heating temperature of the garbage in the furnace, local overheating produces serious pyrolysis side reactions of garbage, and even occurs in the furnace due to local overheating Accidents of carbonization and coking of garbage

In addition, the temperature of the garbage inside the single-layer horizontal furnace is always on a downward trend when it travels from the inlet end to the outlet end. Most of the garbage cannot meet the temperature conditions for pyrolysis and gasification, which affects the efficiency of garbage gasification, poor economy, and large waste of heat energy.

Foreign garbage cracking equipment strictly screens and classifies the garbage entering the cracking furnace in advance to prevent garbage carbonization and coking accidents due to local overheating of the cracking furnace. The entire garbage treatment system is bulky and expensive. Filtering hard-to-achieve countries is unavailable
