Abstract

The invention relates to a refuse landfill gas burning and re-burning technology, and in particular relates to a method and a treatment system for reducing nitrogen oxides by using incineration of refuse landfill gas. The treatment system mainly consists of a refuse landfill, an air pipe, a fan, the other air pipe and an incinerator connected sequentially; during working, the landfill gas of the refuse landfill is led out by the fan through the air pipe, delivered to the incinerator through the other air pipe, and burnt and re-burnt by the incinerator; and the landfill gas is used for reducing NOx in the incinerator, so that the NOx content of the flue gas exhausted by the incinerator is effectively reduced. The method and the system solve the problem of air pollution caused by stench of the refuse landfill and the problem of NOx concentration in the flue gas exhausted by the refuse incinerator, and are particularly suitable for a newly built refuse power plant, particularly a refuse burning power plant which is built nearby the refuse landfill and can provide the landfill gas more conveniently and effectively.

Description

technical field

[0001] The present invention relates to a kind of waste landfill gas combustion and reburning technology, particularly refers to a kind of utilization landfill gas incineration to reduce nitrogen oxides (chemical formula: NOx (hereinafter all use this chemical formula), such as NO 2 , NO, N 2 O etc.) method and processing system thereof. Background technique

[0002] Due to the late development of waste cleaning technology in my country, landfill was the main method in the past. There are a huge number of landfills in our country, and these landfills will discharge a large amount of odorous gas every day, the most important combustible gas is methane (CH 4 ), if it can be used effectively, it will be of great significance to the environment, ecology and economy.

[0003] The main harmful gas in the furnace and exhaust flue gas of the waste incinerator is NOx. NOx is one of the main air pollutants. It not only endangers human health and destroys the atmosp...
