Incineration process for processing ammine containing exhaust gas and system thereof

Abstract

The invention relates to an incineration technique for processing waste gas containing ammonia and a system thereof. The technique is to divide the waste gas containing ammonia into two parts which enter two combustion chambers of an incinerator at the same time. In one combustion chamber, the ammonia in the waste gas containing ammonia is decomposed and oxidized at a high temperature; in the other combustion chamber, the ammonia in the waste gas containing ammonia has oxidation-reduction reaction with NO and NO2 from reaction products of the first combustion chamber. The system comprises an incinerator which has two communicated combustion chambers respectively connected with a processing waste gas containing ammonia supplying system. The incinerator is respectively connected with a fuel gas supplying system and a combustion air assisting system. The reaction products of the two combustion chambers are connected with a reaction product post-processing system. The invention can effectively decrease consumption of the fuel gas and generation of NOX, thus meeting requirements of saving energy and protecting environment.

Description

technical field [0001] The invention relates to a treatment technology for ammonia-containing waste gas, in particular to an incineration process and system for treating ammonia-containing waste gas. Background technique [0002] At present, the incineration treatment of ammonia-containing waste gas generally adopts a one-stage combustion process, that is, all ammonia-containing waste gas enters the furnace for combustion through the burner burner, and produces a large amount of NOX after combustion, which has a large emission rate and high emission concentration; often requires In order to meet the emission requirements of relevant environmental protection standards, a denitrification device is added in the subsequent order. The title of the invention is "gas combustion treatment method and equipment used in the method" (application number is 02132364.X) discloses a gas combustion treatment method for the combustion treatment of ammonia-containing gas and hydrogen sulfide-c...
