Abstract

The invention discloses a SNCR high-efficiency intelligent injection system. The SNCR high-efficiency intelligent injection system comprises a solvent pipeline, a solute pipeline, and a plurality of injection branch pipelines; a solvent flowmeter is arranged on the solvent pipeline; a solute flowmeter is arranged on the solute pipeline; the solvent pipeline and the output end of the solvent pipeline are connected with a mixing pipeline; the mixing pipeline is connected with the injection branch pipelines through a distributor; the solvent flowmeter and the solute flowmeter are connected with a control box through electric connection. The SNCR high-efficiency intelligent injection system is capable of realizing intelligent adjusting on the solute / solvent ratio and using amount flexibly based on different working conditions, so that system flexibility and using performance are improved greatly; and in addition, the whole programming performance is excellent, system complexity is reduced, occupied land area is reduced, and transporation and using are convenient and simple.

Description

technical field [0001] The invention relates to the technical field of industrial combustion flue gas denitrification, in particular to an SNCR high-efficiency intelligent injection system. Background technique [0002] Nitrogen oxides include a variety of compounds, but the main components are nitric oxide and nitrogen dioxide. Nitrogen oxides emitted by human activities are mainly produced by fuel combustion and chemical industry production, such as fixed sources of fuel combustion such as thermal power plants, chemical plants, and steel mills, and mobile sources such as motor vehicles. In addition, industrial production processes and residential life will also produce a small amount of nitrogen oxides. Nitrogen oxides are not only highly toxic to humans, animals and plants, but also the main cause of acid rain, smog and photochemical smog, and also participate in the destruction of the ozone layer. The control and treatment of nitrogen oxide pollution has always been a ...
