Vehicle-mounted scr catalyst on-site regeneration equipment

Abstract

The invention discloses a vehicle-mounted SCR catalyst on-site regeneration equipment, which includes a carrier vehicle, which is provided with a carriage, and the carriage is sequentially provided with a spray cleaning area, a spray cleaning area, an activation solution dipping area, a drying area and In the roasting area, each area is equipped with lifting rails for transporting the SCR catalyst up and down, and the top of each area except the spray cleaning area is also equipped with a shared translation rail for transporting the translation of the SCR catalyst. Ash area, spray cleaning area, control area for lifting track and translation track operation. The regeneration equipment has the advantages of convenient transportation, integration of multiple pools, simple operation, saving manpower and material resources, and high degree of automation.

Description

technical field [0001] The invention mainly relates to the field of flue gas purification, in particular to a vehicle-mounted SCR catalyst on-site regeneration equipment. Background technique [0002] Nitrogen oxides emitted by coal-fired power plants not only pollute the air, but are also the main pollutants that form a series of air pollution events such as acid rain and photochemical smog. In recent years, with the reduction of my country's environmental capacity and the stricter national emission standards for nitrogen oxides, the pressure to reduce nitrogen oxides is increasing. At present, the emission control of nitrogen oxides in coal-fired power plants is mainly divided into pre-combustion and post-combustion. Pre-combustion control mainly includes low-nitrogen combustion technology and re-combustion technology. Post-combustion control mainly includes dry method and wet method. The post-combustion control of coal-fired power plants in my country mainly adopts the S...

Problems solved by technology

However, the life of the catalyst is generally 3 to 5 years due to surface ash clogging, poisoning, and wear, and the cost of the catalyst is high. Therefore, it is necessary to use the method of catalyst regeneration to reduce the operating cost of the SCR system.

[0004] At present, all coal-fired power plants recycle the expired SCR denitrification catalysts and transport them to professional catalyst regeneration companies. After regeneration and activation, they are transported to coal-fired power plants in a unified manner. The operation process is complicated and cumbersome.
