Clean and environment-friendly waste gasification heat storage method and device

Abstract

The invention discloses a clean and environment-friendly waste gasification heat storage method and device. According to the method, the gas is dried in manifold cycles in a drying chamber and then goes into a combustion chamber; the high-temperature gas obtained after combustion goes into a combustor to store heat and perform secondary drying on the drying chamber; combustion residue is discharged by use of a chain tray; the waste heat gas used by the combustor goes into the jacket of the drying chamber to heat the jacket; the device comprises a stove and a gas-tight chamber arranged beside the stove; a lifting feeding device is arranged in the gas-tight chamber; the upper end of the gas-tight chamber is communicated with the feeding hole of the stove; the drying chamber is arranged in the stove; a layer of jacket is arranged outside the drying chamber; the combustion chamber is arranged under the drying chamber; the drying chamber is communicated with the combustion chamber by use of a feeding hole; the chain tray is arranged at the bottom of the combustion chamber; a slag outlet is formed in the outlet end of the chain tray; the combustion chamber is connected with the combustor by use of a fire outlet duct; the outlet of the combustion is communicated with the jacket; the smoke outlet is formed in the jacket; a moisture outlet is formed in the drying chamber.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a method and device for gasifying, cleaning, and environment-friendly heat storage of garbage. Background technique [0002] Household garbage is a large amount of waste produced in people's lives. Once it accumulates too much, it will seriously affect people's life and living environment. Therefore, the problem of garbage disposal has become a very important item in environmental protection. At present, the way of garbage disposal has changed from landfill to incineration. In various garbage incinerators, there are many complicated structures in order to prevent air pollution. Therefore, the cost of various garbage incinerators is very high, and many of them cannot Carrying out economical operation, or adding fuel to support combustion, or adding a lot of equipment consumes a lot of electricity. [0003] At present, large-scale waste incinerators are mainly used. Boilers are in...

AI Technical Summary

Problems solved by technology

[0004] 1. After the hot gas is used by the boiler, it is directly processed through the tail gas, and a large amount of heat energy is not used;

[0005] 2. The hot gas is directly heated to the boiler, the heating effect is slow, and the heating is not ideal;

[0006] 3. The components in the hot gas are complex, not clean enough and environmentally friendly, resulting in high flue gas treatment costs;

[0007] 4. The structure is complex and the cost and maintenance cost are high
