Low-temperature dust collection, desulfurization and denitrification system

Abstract

The invention discloses a low-temperature dust collection, desulfurization and denitrification system. The low-temperature dust collection, desulfurization and denitrification system comprises a desulfurization chamber and a denitrification chamber, wherein the denitrification chamber is formed at one side of the desulfurization chamber; a first connecting pipe is arranged between the desulfurization chamber and the denitrification chamber; a desulfurization charging valve and a denitrification charging valve are arranged on the first connecting pipe; the denitrification charging valve is arranged on one side of the desulfurization charging valve; a first rotating rod is arranged in the desulfurization chamber; first water bath pipes are arranged on two sides of the first rotating rod; first water bath holes are formed in the first water bath pipes; a first ring gear is arranged on the outer side of the end part of the first rotating rod; a first motor is arranged at the top of the desulfurization chamber. Ammonia water is used as a reactant, so that the ammonia water is subjected to a reaction with SO2 and NOx in mixed gas, a purifying effect is realized, sewage treatment is not needed after purification, manpower and money are saved, (NH4)2SO3 capable of being used as fertilizer can be also obtained, and accordingly, the effects of avoiding pollution and using waste are achieved.

Description

technical field [0001] The invention relates to the technical field of flue gas discharge systems, in particular to a low-temperature dust removal, desulfurization and denitrification system. Background technique [0002] Energy and the environment involve people's living and living environment. Although my country is a big economy, it is still relatively backward in terms of energy. The steel, kerosene and power generation industries still use coal as primary energy, and the exhaust gas after coal combustion will cause Air pollution, among them, SO2 and NOx in the exhaust gas are the main causes of acid rain, and the absorption of SO2 and NOx by the human body will increase the risk of human cancer. [0003] Therefore, it is necessary to invent a low-temperature dedusting desulfurization and denitrification system to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a low-temperature dedusting, desulfurization a...
