Waste incineration equipment

Abstract

The invention discloses waste incineration equipment which comprises a pyrolysis gasification furnace, an oxygen generating device, a rapid smoke cooling system and a heating system. The pyrolysis gasification furnace comprises a gas inlet and a smoke outlet. An oxygen outlet of the oxygen generating device is communicated with the gas inlet. The rapid smoke cooling system is communicated with the smoke outlet and is used for cooling the smoke. The heating system is used for heating a cooling medium of the rapid smoke cooling system. The garbage incineration equipment is provided with the oxygen generating device, the rapid smoke cooling system and the heating system, so that oxygen can be supplemented into the pyrolysis gasification furnace, waste in the furnace can be sufficiently combusted, and dioxin is prevented from being generated; due to the arrangement of the rapid smoke cooling system, smoke can be cooled in time, and regeneration of dioxin is inhibited; and meanwhile, the heating system can heat the cooling medium of the rapid smoke cooling system, so that the cooling medium is prevented from being frozen, and it is ensured that the waste incineration equipment can operate in the plateau alpine region.

Description

technical field [0001] The invention relates to the technical field of waste incineration, and more specifically, relates to a waste incineration equipment. Background technique [0002] With the rapid development of economy and urban construction, the amount of garbage generated is also increasing year by year, and environmental problems are becoming increasingly serious. Waste incineration has become the main method of waste disposal due to its small footprint, high processing efficiency, and resource utilization. [0003] In plateau and alpine regions, due to the low oxygen content of air at high altitudes, it is easy to cause insufficient waste incineration, which in turn produces harmful substances such as dioxins and pollutes the environment; therefore, in order to ensure sufficient combustion, a large amount of air needs to be introduced , that is, local low-temperature low-oxygen air, but this method will cause disturbances in the furnace temperature, thereby increa...

AI Technical Summary

Problems solved by technology

[0003] In plateau and alpine regions, due to the low oxygen content of high-altitude air, it is easy to lead to insufficient waste incineration, which in turn produces harmful substances such as dioxins and pollutes the environment; therefore, in order to ensure sufficient combustion, a large amount of air needs to be introduced , That is, the local low-temperature low-oxygen air, but this method will cause disturbances in the furnace temperature, thereby increasing fuel consumption

In addition, the decomposed dioxins in the high-temperature flue gas are easily regenerated in high-temperature environments, so it is necessary to quench the high-temperature flue gas in time to reduce the flue gas below 250°C to inhibit the re-generation of dioxins; However, due to the low temperature in plateau and alpine regions, it is easy to block the pipeline of the flue gas water cooling equipment due to freezing, which will affect the operation of the equipment
