An intelligent catalytic desulfurization tower

Abstract

The present invention proposes an intelligent catalytic desulfurization tower. The desulfurization tower includes a tower main body and an oxidation section, a reaction section, an adsorption section and a secondary reaction section arranged sequentially from bottom to top inside the tower main body. The flue gas is oxidized in the oxidation section, soluble salts are formed in the reaction section, impurities and water vapor are adsorbed in the adsorption section, and finally the secondary reaction treatment is carried out in the secondary reaction section to obtain the flue gas with relatively complete final treatment and no harmful gases . By adopting the desulfurization tower of the present invention, the partition management of each reaction stage is effectively realized, and the desulfurization efficiency and intelligent management of flue gas desulfurization treatment are improved.

Description

technical field [0001] The invention relates to the technical field of desulfurization towers, in particular to an intelligent catalytic desulfurization tower. Background technique [0002] Since the beginning of the 21st century, my country's economy has developed rapidly, and the demand for energy is also increasing. Coal, as a primary energy source, is still the main energy source in our country for a long period of time. In large power plants and chemical plants, many processes such as coal combustion, sulfuric acid production, metal smelting, etc. will produce a large amount of sulfur dioxide, which is one of the main pollutants in the atmosphere. A large amount of sulfur dioxide discharge not only seriously pollutes the environment, but also causes a huge waste of sulfur resources. Therefore, it is urgent to actively promote desulfurization technology, reduce sulfur dioxide emissions and protect the environment. [0003] As the country pays more and more attention to ...

Problems solved by technology

A large amount of sulfur dioxide discharge not only seriously pollutes the environment, but also causes a huge waste of sulfur resources. Therefore, it is urgent to actively promote desulfurization technology, reduce sulfur dioxide emissions and protect the environment.

Wet flue gas desulfurization technology includes the most widely used limestone (lime)-gypsum method and magnesium method. The former has the advantages of fast desulfurization reaction speed, simple equipment, and high desulfurization efficiency, but it generally suffers from severe corrosion, high operation and maintenance costs and easy Cause secondary pollution and other problems. The latter has the advantages of high removal rate, high operation rate, and good economic benefits of by-products. The main problem is that the unit price of absorbent is high and the by-product equipment is complicated; in addition, there is ammonia method, because its by-product Ammonium sulfate is easy to block the pipeline, so that the process cannot run normally, and the application is limited

In addition, in the traditional flue gas desulfurization process, the process of flue gas desulfurization cannot be controlled step by step according to the demand, so that there are problems of incomplete flue gas desulfurization and waste of desulfurization agent in the desulfurization process
