Industrial boiler denitration system

Abstract

The invention discloses an industrial boiler denitration system; a denitration mechanism, a flue gas absorption pipeline, a desulphurization absorbing tower, an underground spray dedusting flue and a gas analyzer are arranged so as to remove pollutants like sulfide, nitrogen oxide and dusts from waste gas discharged by industrial boilers; the processed waste gas quality can be monitored in real time, and intelligent adjustment can be carried out according to monitoring data of the gas analyzer, thus providing best waste gas processing effect; the industrial boiler denitration system comprises the denitration mechanism, the flue gas absorption pipeline, the desulphurization absorbing tower, the underground spray dedusting flue and the gas analyzer; the denitration mechanism comprises a liquid storage tank, a water pump, a convey pipeline and a control module, wherein the liquid outlet of the convey pipeline is arranged on to-be-denitrated equipment; the liquid storage tank, the water pump, and the convey pipeline are connected in sequence; the desulphurization absorbing tower comprises a nozzle, two dispersion impellers, a convey pump and a liquid storage pool arranged in the tower from top to bottom, wherein the nozzle, the convey pump and the liquid storage pool are connected in sequence.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an industrial boiler denitrification system. Background technique [0002] There are two types of industrial boiler products. One is steam, which is used for power generation or gas supply. For example, chemical fertilizer plants can be vaporized with steam, and coal is used as raw material to synthesize chemical fertilizers. This is a typical industrial boiler. Industrial boilers still use coal as the main component Most, gas-fired waste heat boilers are generally used to recover waste heat. [0003] For a long period of time in the future, coal-fired industrial boilers will still be the leading products in my country, and most of them are medium and large capacity (single evaporation ≥ 10t / h). However, coal-fired boilers will cause serious environmental pollution. For example, the exhaust gas from coal-fired boilers contains a large amount of sulfur dioxide, soot and nitrogen oxides. ...

Problems solved by technology

However, coal-fired boilers will cause serious environmental pollution. For example, the exhaust gas from coal-fired boilers contains a large amount of sulfur dioxide, soot and nitrogen oxides. If these exhaust gases containing a large amount of polluting gases are directly discharged into the atmosphere, they will affect the air environment Cause serious pollution, but also affect the lives of residents around the factory

In the prior art, direct discharge is generally used for treatment, and some ammonia water is used to remove nitrogen oxides in the exhaust gas. However, due to the instability of ammonia water and the inability to remove sulfides in the exhaust gas, the exhaust gas of coal-fired industrial boilers still contain a lot of pollutants
