Embodiment Construction

[0031] The system for integrated treatment of mixed exhaust gas of the present invention includes a first wet processor 11 , 21 or 31 , a decomposition reactor 12 , 22 or 32 and a second wet processor 13 , 23 or 33 . The system for integrally treating mixed exhaust gas of the present invention can be used for integrally treating the above-mentioned mixed exhaust gas, and can be implemented as first to third examples as described in detail below.

[0032] The first wet processor 11, 21 or 31 washes and adsorbs gas, SO x and dust including ash.

[0033] The decomposition reactor 12, 22 or 32 receives exhaust gas from the first wet processor 11, 21 or 31, and decomposes nitrogen oxides (NO x and N 2 O), CFCs, HCFCs, HFCs and PFCs.

[0034] The second wet processor 13, 23 or 33 receives the waste gas decomposed in the decomposition reactor 12, 22 or 32, and performs washing and adsorption treatment on it.

[0035] Each of the first wet processor 11, 21 or 31, the decomposition...

Abstract

Provided is an integrated treatment system for composite waste gas comprising nitrogen oxides (NOx and N2O), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and perfluorinated compounds (PFCs). The integrated treatment system comprises: a first wet treatment apparatus for washing and adsorption-treating a gas to be dissolved in water, SOx and dust includingash; a decomposition reactor for receiving the waste gas treated by the first wet treatment apparatus and treating nitrogen oxides, CFCs, HCFCs, HFCs and PFCs; and a second wet treatment apparatus for receiving the waste gas treated in the decomposition reactor and washing and adsorption-treating the same. The system can effectively treat a large amount of composite waste gas.

Description

technical field [0001] The present invention relates to the field of monolithic treatment of mixed exhaust gases, more particularly, the present invention relates to a monolithic system for mixed exhaust gases including nitrogen oxides, chlorofluorocarbons, hydrochlorofluorocarbons, hydrofluorocarbons and perfluorinated compounds processing system. Background technique [0002] Various nitrogen oxides exist depending on the bonding state of nitrogen and oxygen. The nitrogen oxides produced by fuel combustion mainly include nitrogen monoxide (NO), nitrogen dioxide (NO 2 ), nitrogen trioxide (N 2 o 3 ) and dinitrogen pentoxide (N 2 o 5 ). These compounds are commonly referred to as nitrogen oxides (hereinafter referred to as "NO x "). [0003] NO / NO in combustion gas discharged from boiler combustion equipment x The volume ratio is about 90% to 95%, and the NO in the exhaust gas x Mainly includes nitric oxide (NO). Nitric oxide (NO) is a colorless, odorless gas and ...
