Smoke filtration desulfurization and denitrification treatment equipment

Abstract

The invention relates to smoke filtration desulfurization and denitrification treatment equipment which comprises a mounting base plate, a cooling sleeve part and a treatment sleeve part. The coolingsleeve part and the treatment sleeve part are sequentially arranged on the mounting base plate from left to right. The problems that in existing flue gas electron beam ammonia process desulfurizationand denitrification treatment: a, the flue gas needs to be cooled and humidified in the existing flue gas is subjected to electron beam ammonia process desulfurization and denitrification treatment, but the flue gas is often accompanied by a certain high temperature in the production process, so that the situation that the flue gas is incompletely cooled is extremely pone to occurring, and the desulfurization and denitrification effects are influenced; and b, when the existing flue gas is subjected to electron beam ammonia process desulfurization and denitrification treatment, water vapor is often required to be sprayed into the flue gas, so that the flue gas is humidified, polluted water is prone to being formed when a large amount of water vapor is sprayed, the polluted water is prone toflowing into the environment during cleaning, and the condition of water source pollution is caused are solved.

Problems solved by technology

[0002] Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology applied to the chemical industry where nitrogen oxides and sulfur oxides are generated. Among them, nitrogen oxides and sulfur oxides are one of the main sources of air pollution, so flue gas desulfurization is used Denitrification technology has great benefits for air purification. Currently known flue gas desulfurization and denitrification technologies include ammonium phosphate fertilizer method flue gas desulfurization technology, activated carbon fiber method flue gas desulfurization technology, pyrolusite method, electron beam ammonia method flue gas desulfurization and denitration technology technology, pulse corona method, gypsum wet method, catalytic oxidation method and microbial degradation method. Among them, the electron beam ammonia method flue gas desulfurization and denitrification technology has the characteristics of low investment, low operating cost, easy operation and maintenance, and high reliability. It has been widely used, but the existing electron beam ammonia flue gas desulfurization and denitrification technology still has certain deficiencies in the flue gas desulfurization and denitrification treatment.

[0003] The following problems exist in the existing flue gas desulfurization and denitration treatment by electron beam ammonia method: a: When the existing flue gas is subjected to electron beam ammonia desulfurization and denitrification treatment, it is necessary to cool and humidify the flue gas, but the flue gas Production is often accompanied by a certain high temperature, which is prone to incomplete cooling of the flue gas, which affects the desulfurization and denitrification effect; b: when the existing flue gas is subjected to electron beam ammonia desulfurization and denitrification treatment, it is often necessary to treat the flue gas Spraying water vapor makes the flue gas wet. When a large amount of water vapor is sprayed, it is easy to form polluted water, so it is easy to flow into the environment during cleaning, resulting in water source pollution.
