Three-stage tail gas purification tower for high-concentration nitric oxide

Abstract

The invention belongs to the technical field of nitric oxide tail gas purification towers, and particularly relates to a three-stage tail gas purification tower for high-concentration nitric oxide. The tower comprises a tower body; a gas inlet pipe is fixedly connected to the center line of the tower body and in the inner wall below the tower body; a filter plate is fixedly connected into the inner wall of the tower body, and a purification cavity is formed below the filter plate; an adsorption liquid is contained in the purification cavity; blocky flourishing carbon is contained in the purification cavity; and a motor is fixedly connected to the upper end surface of the filter plate and located at the center line of the filter plate, and the motor is electrically connected with a controller through a wire. The tower is mainly used for solving the problems that a nitric oxide purification tower device in the prior art is large in occupied area, moving and overhauling are inconvenient,meanwhile, high-concentration NOx treatment needs to be supplemented with air to be diluted, the process steps of the nitric oxides are increased, waste water and waste residues are prone to being generated, the generated waste water and waste residues need to be subjected to secondary treatment, and the process steps of nitric oxide purification are increased.

Description

technical field [0001] The invention belongs to the technical field of nitrogen oxide tail gas purification towers, in particular to a high-concentration nitrogen oxide three-stage tail gas purification tower. Background technique [0002] Nitrogen oxide (NOx) is a kind of highly toxic yellow smoke. It is discharged into the atmosphere through the chimney without treatment, forming eye-catching brown (red) yellow smoke, commonly known as "Huanglong". NOx is the most difficult in many exhaust gas treatments. It is The culprit of air pollution. If it is not effectively controlled, it will not only cause great harm to the health of the operators and the environment of the factory area, but also cause public hazards to the lives of surrounding residents and the ecological environment if it spreads with the wind. Experts predict that if the control is not strengthened, nitrogen oxides will become the main pollutant of air pollution in China after 2010. In emission standards for...

Problems solved by technology

[0006] In order to make up for the deficiencies in the prior art, the present invention proposes a high-concentration nitrogen oxide three-stage tail gas purification tower. It is inconvenient in the process of maintenance and maintenance. At the same time, for the treatment of high-concentration NOx, air needs to be supplemented to dilute it, thereby increasing the process steps of nitrogen oxides, and it is easy to generate waste water and waste residue. Problems with the process steps of nitrogen oxide purification
