Problems solved by technology

[0003] However, due to the large amount of harmful gases produced during the waste incineration process, and the amount of these harmful gases is closely related to the furnace temperature and oxygen content; and because of the complexity and diversity of the composition of domestic waste, when the furnace temperature is high when burning It will exceed 1100°C, and may fall below 850°C when it is low; the oxygen content at the outlet of the waste heat boiler (hereinafter referred to as the boiler) is about 12% when it is high, and even less than 1% when it is low

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following examples.

[0020] Such as figure 1 As shown, a clean incineration device for domestic waste includes a furnace body with a garbage hopper 1, a furnace 2 disposed in the furnace body, an incineration grate 3 disposed at the bottom of the furnace, and a waste heat boiler 20 communicated with the furnace through a flue 1. A flue gas purification system for treating the flue gas discharged from the waste heat boiler. The above is the structure of a conventional incineration device.

[0021] The incineration device of the present invention also includes an optimized air distribution system located at the bottom of the furnace body, and the optimized air distribution system includes a primary air system, a secondary air system and a flue gas recirculation system.

[0022] The primary air system includes a blower 6 com...

Abstract

The invention relates to a clean incineration device for household garbage, and aims to adjust the content of oxygen in a boiler, reduce noxious gas generated in a household garbage incineration process, and achieve the energy-saving and environment-friendly characteristics. According to the technical scheme, the clean incineration device comprises a furnace body, a furnace hearth, a waste heat boiler, a flue gas cleaning system and a chimney, wherein the furnace body is equipped with a garbage feeding hopper; the furnace hearth is arranged in the furnace body and an incineration furnace grate is arranged at the bottom of the furnace hearth; the waste heat boiler communicates with the furnace hearth; the flue gas cleaning system is used for treating flue gas discharged from the waste heat boiler; and the chimney is used for exhausting gas discharged from the flue gas cleaning system through an induced draft fan. The clean incineration device is characterized by further comprising an optimized air distribution system.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a clean incineration device for domestic garbage. Background technique [0002] With the rapid development of the economy and society, the steady improvement of residents' lives, the output of domestic waste (especially municipal solid waste) has increased sharply, and the simple landfill method can no longer meet the needs of waste disposal. Waste incineration power generation is characterized by its "harmless" , Reduction, resource utilization" advantages have been developed rapidly. [0003] However, due to the large amount of harmful gases produced during the waste incineration process, and the amount of these harmful gases is closely related to the furnace temperature and oxygen content; and because of the complexity and diversity of the composition of domestic waste, when the furnace temperature is high when burning It will exceed 1100°C, and may fall below 850°C wh...
