Vertical vibration high-temperature superconducting-tube pyrogasification furnace for garbage

Abstract

The invention relates to a vertical vibration high-temperature superconducting-tube pyrogasification furnace for garbage. The vertical vibration high-temperature superconducting-tube pyrogasificationfurnace is composed of four parts, i.e., a circular cylinder furnace body, a high-temperature superconducting heat exchanger, a furnace body vibrator and a heater. The vertical vibration high-temperature superconducting-tube pyrogasification furnace is characterized in that the high-temperature superconducting heat exchanger is arranged between the upper and lower flange plates of the circular cylinder furnace body. The heater uses gas produced by the cracking furnace for heating the superconducting-tube evaporation section of the high-temperature superconducting heat exchanger in the exteriorof the furnace body, and generated high-temperature radiant heat can be rapidly transmitted to garbage vibrated in the furnace via the high-temperature superconducting heat exchanger, thereby completing rapid, high-efficiency and continuous pyrogasification of the garbage. The pyrogasification furnace provided by the invention has high temperature and balanced furnace temperature, so the dangersof bonding, bulging, block-forming and coking of the garbage caused by local overheating in the furnace are effectively solved, the generation of glue gas is avoided, pollution of harmful substances released by cracked substances to the environment are shielded, and the generation of dioxin is suppressed; and solid residues produced after cracking can be used as a chemical raw material for manufacturing of active carbon, and obvious social benefits and economic benefits are produced.

Description

Technical field: [0001] The invention relates to a domestic waste treatment device, in particular to a low energy consumption and high efficiency vertical vibrating high temperature superconducting pipe waste pyrolysis gasifier. Background technique [0002] The disposal of municipal solid waste has become an important task for the coordinated development of energy, environment and society, and an important and urgent task for governments at all levels in our country. [0003] Pyrolysis and gasification of domestic waste is an advanced technology to realize waste reduction, harmlessness, and resource utilization. Today, the "garbage besieged city" has become a public hazard, and the use of pyrolysis and gasification technology to treat waste has been highly valued by the Chinese government. [0004] The pyrolysis gasification of garbage is to put domestic garbage in a special equipment, and under a certain temperature and pressure, a series of chemical reactions will occur b...

AI Technical Summary

Problems solved by technology

[0005] At present, in the process of garbage disposal in my country, vertical furnaces are used to incinerate "gasified" garbage. The garbage is basically incinerated in the incinerator, which emits a large amount of smoke, particulate matter, acid gas, unburned waste, heavy metals and trace amounts of waste. Organic compounds, etc., will produce a large amount of carcinogenic dioxins, the amount of waste reduction is low, the ash residue needs to be treated later, continuous operation cannot be performed, and the operating cost and fixed investment are very high

There are also traditional cracking furnaces used to treat garbage, but the existing traditional single-wall cracking furnace reaction zone does not have a temperature balance device, which cannot maintain a relatively balanced high temperature and pressure in the reaction zone, making it difficult for the cracking furnace to continuously and stably produce combustible gases , and cannot avoid the generation of smoke, and cannot shield the harmful molecules released by the lysate from polluting the environment

In particular, the traditional cracking furnace body has a single-tube single-layer structure, and the heater heats the single-layer furnace body at a high temperature locally outside the furnace body, and the radiant heat is transmitted to the locally heated garbage through the single-layer furnace body. The axial length is long, and the single-layer furnace body is partially exposed to the high temperature of the thousand-degree flame. The inhomogeneity of the temperature field along the axial and radial directions of the furnace body leads to uneven heating temperature of the garbage in the furnace, resulting in local overheating and side effects of garbage cracking. , and even accidents of garbage carbonization and coking occurred in the furnace due to local overheating

In addition, the temperature of the garbage in the single-layer horizontal furnace is always falling when it travels from the inlet end to the outlet end. Most of the garbage cannot reach the temperature conditions for cracking and gasification, which seriously affects the efficiency of garbage cracking and gasification, and the economy is poor.
