Abstract

The invention provides a two-channel advanced oxidation apparatus and a flue gas purification system using the two-channel advanced oxidation apparatus. The flue gas purification system comprises a flue gas output device, a heat recovery device, a dust removal device, a two-channel advanced oxidation apparatus, an oxidant feeding device, a purification removal reaction device, a removal agent supply device and a gas discharge device, wherein the two-channel advanced oxidation apparatus comprises a body, a gas inlet, a first gas outlet, an oxidant feeding port, a gas channel separation plate and a waste discharge port, the interior of the body is divided into a first gas channel and a second gas channel by the gas channel separation plate, the gas inlet ends of the first gas channel and thesecond gas channel are communicated to the gas inlet, the oxidant feeding port is arranged at the first gas channel and close to the gas inlet end, a mixed reaction zone is formed inside the first gas channel, the gas outlet end of the first gas channel is communicated to the first gas outlet, and the second gas outlet is connected to the gas inlet of the purification removal reaction device or the gas discharge device. According to the present invention, the technical scheme can significantly reduce the ozone adding amount when the same NO removal rate requirement is met so as to substantially reduce the operation cost.

Description

technical field [0001] The invention relates to a flue gas purification device and system, in particular to a dual-channel advanced oxidation device and a flue gas purification system using the same, belonging to the field of flue gas purification treatment. Background technique [0002] With the rapid development of my country's economy in recent years, the pollution of our country's environment, especially the atmospheric environment, has become increasingly prominent. Among them, the pollution of sulfur oxides and nitrogen oxides produced in the process of production and waste treatment is particularly serious. In addition, there are still Contains a small amount of heavy metals (such as mercury), HCl, HF, inhalable particulate matter (IP), dioxins (PCDD / Fs) and other pollutants. [0003] For example, in the process of waste incineration, if the waste incineration is not handled properly, the tail gas produced by the incineration will contain sulfur oxides, nitrogen oxides...
