Non-polluting waste cracking gasifier with high-temperature superconducting tube

Abstract

A non-polluting waste cracking gasifier with a high-temperature superconducting tube comprises a furnace cover, a furnace body, a furnace seat, a high-temperature superconducting heat exchanger, a rotating smoke tube radiator, a heater, a feeder and a superconducting waste heat recovery device, the high-temperature superconducting heat exchanger is arranged in the furnace body, the heater in the furnace seat at the lower portion of the furnace body uses combustion gas self-produced by the cracking gasifier to heat the evaporation section of the high-temperature superconducting heat exchanger,and high-temperature radiant heat is quickly conducted to wastes moving in the upper portion of the furnace body from different angles through the high-temperature superconducting heat exchanger, therotating tube radiator and a round head heat exchanger in order to complete efficient and rapid cracking gasification of the wastes under a high-temperature anoxic condition. The cracking gasifier hasthe advantages of high temperature, balanced furnace temperature, large gas yield, effectiveness in overcoming the bonding, bubbling, caking and coking dangers formed by local overheating of the wastes in the furnace, avoiding of the generation of cracking flue gas, shielding of the pollution of harmful substances released by a cracked substance to the environment, and achieving of significant avoiding social and economic benefits by using the residual gas obtained after cracking to generate electricity and using solid waste residues as an activated carbon chemical raw material.

Description

[0001] Technical field: [0002] 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 [0003] 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, ...

Problems solved by technology

[0006] 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. It is difficult to continuously and stably generate combustible gas in waste treatment, and the generation of smoke and tar cannot be avoided. 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
