Desulfurizing and denitrifying agent for smoke gas

Abstract

The invention discloses a smoke gas catalyst capable of simultaneously realizing desulfurization and denitrification, which aims to provide a desulfurizing and denitrifying agent for CTR-ultraviolet radiation smoke gas capable of reducing the investment and operation costs of the device and simultaneously efficiently removing the NO, NO2 and SO2 in the smoke gas. The moke gas desulfurizing and denitrifying catalyst provided by the invention may comprise the following components according to fractional ratio: 40-100% of calcium-based imvite, 0-40% of calcium oxide, 0-20% of iron oxide, 0-30% of carbonate and 0-10% of titanium dioxide, wherein the iron oxide is one or more types of ferrous oxide, iron sesquioxide and ferroferric oxide, and the carbonate is one or more types of calcium carbonate and magnesium carbonate. The desulfurizing and denitrifying agent for CTR-ultraviolet radiation smoke gas is not only suitable for the flue gas desulfurization of a new boiler but also particularly suitable for the improvement in order to construct a combustion device.

Description

technology field; [0001] The invention relates to a desulfurization and denitrification agent, in particular to designing a flue gas desulfurization and denitrification agent Background technique: [0002] The desulfurizers traditionally used in coal-fired power plants are mainly limestone and calcium hydroxide. For example, Finland's LIFAC flue gas desulfurization technology, American ABB's wet flue gas desulfurization technology and semi-dry flue gas desulfurization technology (NID system), etc. There are also NH 3 As a desulfurizing agent technology, such as the electron beam flue gas desulfurization technology researched in Japan. Although the desulfurizers used in these technologies are cheap, due to the complex desulfurization process, the desulfurization system equipment is very large and the operation is also very complicated, and there are many limitations in actual use. For example, it has many shortcomings such as large floor area, large amount of dosing, and h...

Although the desulfurizers used in these technologies are cheap, due to the complexity of the desulfurization process, the desulfurization system equipment is very large and the operation is also very complicated, and there are many limitations in actual use.

For example, it has many shortcomings such as large floor area, large amount of dosing, and high one-time investment.

At the same time, these technologies cannot achieve the purpose of denitrification at the same time, which is undoubtedly unfavorable to the transformation of combustion equipment.
