Vertical closed type garbage incineration kiln

Abstract

A vertical closed type garbage incineration kiln comprises a kiln body. A garbage feeding bin is arranged in the upper portion of the kiln body. A garbage feeding port communicating with the garbage feeding bin is arranged above the kiln body. A preheating drying area communicating with the garbage feeding bin is arranged below the garbage feeding bin. A pyrolysis area communicating with the preheating drying area is arranged in the middle portion of the kiln body. A pure-oxygen high-temperature dissolving area is arranged in the bottom of the kiln body and communicates with the pyrolysis areathrough a pure oxygen combustion area. A plurality of carbon monoxide connection-in ports evenly distributed circumferentially are formed in the outer wall of the kiln body and communicate with the pyrolysis area. A plurality of first pure oxygen spray guns which are evenly distributed circumferentially and communicate with the pure oxygen combustion area are arranged on the outer wall of the kiln body. The vertical closed type garbage incineration kiln can effectively avoid generation of dioxin in the garbage incineration process, discharged gas cannot carry the harmful dioxin, and environment friendliness and safety of the environment are protected.

Description

technical field [0001] The invention relates to a vertical closed garbage incineration kiln. Background technique [0002] Garbage incineration kiln is a device for incinerating garbage. Garbage is burned in the kiln and turned into waste gas, which enters the secondary combustion chamber, burns completely under the forced combustion of the burner, and then enters the spray dust collector. After dust removal, it is discharged into the atmosphere through the chimney , but the traditional waste incineration kiln will inevitably produce dioxin during the incineration process. Dioxin is a toxic gas. If it is discharged into the air, it will cause serious damage to the environment and pose a threat to human health. Moreover, the temperature of traditional waste incineration kilns will drop when the flue gas is discharged. Once the temperature drops, a large amount of dioxins will be produced, resulting in a large amount of dioxins in the discharged gas. Under the environment, it...

[0002] Garbage incineration kiln is a device for incinerating garbage. Garbage is burned in the kiln and turned into waste gas, which enters the secondary combustion chamber, burns completely under the forced combustion of the burner, and then enters the spray dust collector. After dust removal, it is discharged into the atmosphere through the chimney , but the traditional waste incineration kiln will inevitably produce dioxin during the incineration process. Dioxin is a toxic gas. If it is discharged into the air, it will cause serious damage to the environment and pose a threat to human health. Moreover, the temperature of traditional waste incineration kilns will drop when the flue gas is discharged. Once the temperature drops, a large amount of dioxins will be produced, resulting in a large amount of dioxins in the discharged gas. In the environment, it will even endanger people's life safety. The current waste incineration kiln is limited by its own structure, resulting in limited incineration temperature, which makes it impossible to incinerate electronic waste, medical waste and metal waste.
