Flue gas denitration equipment

Abstract

The invention discloses flue gas denitration equipment, which comprises a mixing chamber, a denitration chamber, a conveying pipe device, an ammonia spraying device and a gas inlet pipe. The conveying pipe device is fixedly connected between the mixing chamber and the denitration chamber, the gas inlet pipe is fixed to one side of the bottom of the surface of the mixing chamber and communicates with the mixing chamber, one end of a zigzag pipeline is communicated with one side of the top of the mixing chamber, the end, away from the mixing chamber, of the zigzag pipeline is communicated with one side of the bottom of the surface of the denitration chamber, a first-stage mixing device is arranged in the zigzag pipeline and close to the mixing chamber, and a secondary mixing device is arranged in the zigzag pipeline and is close to the denitration chamber. The invention relates to the technical field of denitration equipment. According to the flue gas denitration equipment, the purpose of uniform mixing is achieved, flue gas and ammonia gas can make full contact, mixing is rapid and uniform, follow-up denitration work is facilitated, emission of harmful substances is reduced, pollution to the environment is reduced, human health is facilitated, and the use performance is improved.

Description

technical field [0001] The invention relates to the technical field of denitration equipment, in particular to a flue gas denitration equipment. Background technique [0002] Flue gas denitrification is mainly to remove the nitrogen oxides in the flue gas, so as to avoid the pollution of the atmosphere, soil and water due to the high concentration of nitrogen oxides discharged into the atmosphere. Whether burning garbage in daily life or in industrial manufacturing, it is inevitable that a large amount of smoke will be produced. Many substances in the smoke contain nitrate elements, which will pollute the environment when discharged into the air, and will cause harm to people's health after being inhaled by the human body. serious hazard. China is a country where coal is the main energy source. Coal accounts for 75% of primary energy, of which more than 84% is used through combustion. Nitrogen oxides (NOx) in the exhaust gas released by coal combustion are the main atmosphe...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a flue gas denitrification equipment, which solves the problem that the traditional flue gas denitrification equipment only passes flue gas and ammonia gas into the mixing chamber, and then passes the mixed gas into the denitrification chamber. It cannot be fully mixed, which makes the mixing effect poor, which directly affects the reduction degree of nitrogen oxides in the flue gas, which in turn makes the denitrification effect poor and reduces the problem of performance
