Flue gas desulfurization and denitrification complete equipment based on high-efficiency catalytic technology

Abstract

The invention relates to a complete set of equipment for flue gas desulfurization and denitrification based on high-efficiency catalytic technology, including a bag filter, a smoke chamber, a conical ash hopper, an ammonia water treatment room, an activated carbon fluidization chamber and a cyclone dust collector. The bag filter and The boiler flue gas pipes are connected, and the bag filter is connected to the upper left side wall of the smoke chamber through the first pipe. The bottom of the smoke chamber is equipped with a conical ash hopper connected to it, An ash unloading valve is installed at the discharge port of the smoke chamber, and the smoke chamber is connected with the ammonia water treatment chamber through a second pipe, one end of the second pipe is connected to the top of the right end of the smoke chamber, and the other end of the second pipe is connected from above Extending into the bottom of the ammonia water treatment chamber, the top of the ammonia water treatment chamber is connected to the side wall of the lower end of the activated carbon fluidization chamber through a third pipeline, and the exhaust port on the top of the activated carbon fluidization chamber is connected to the cyclone separator. The design has the advantages of simple structure, easy manufacture, practicality and high efficiency.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a complete set of flue gas desulfurization and denitration equipment based on high-efficiency catalytic technology. Background technique [0002] my country is rich in coal resources and is also the world's largest coal producer and consumer. And in our country, about 84% of coal is burned directly. A large amount of coal burning has caused the air pollution mainly of soot type in my country and produced a large amount of SO 2 and NO x , Environmental pollution such as acid rain, greenhouse effect and ozone layer destruction caused by these pollutants has seriously affected the living environment of human beings, and has attracted great attention from the country. Desulfurization and denitrification of flue gas has become an important task in our country. [0003] In the 1980s, people gradually realized that using desulfurization and denitrification technologies alone requir...

Problems solved by technology

[0003] In the 1980s, people gradually realized that using desulfurization and denitrification technologies alone requires complex equipment, large floor space, and high investment and operating costs, while the use of desulfurization and denitrification integrated equipment and processes has compact structure and low investment and operating costs.

At present, combined desulfurization and denitrification technologies: activated carbon method, SNOX process, NOXSO process, electron beam method, etc. are relatively mature, but their large-scale application is restricted due to high operating costs.
