Problems solved by technology

A large amount of exhaust gas in the flame space of the melting pool enters the air regenerator, passes through dust removal, and then enters the denitrification tower first, and then enters the desulfurization tower through the induced draft fan. Due to the limited space of the desulfurization and denitrification tower, the exhaust gas may not fully react with its catalyst, resulting in incomplete treatment. nitrogen oxides and sulfides, which are then discharged directly into the atmosphere

Abstract

The invention discloses a glass factory waste gas denitration method and belongs to the technical field of waste gas purification. A gas chamber is included. An air heat storage chamber is arranged onone side of the gas chamber, and a dust removing box is arranged at the output end of the air heat storage chamber. A gas return pipe is arranged between the dust removing box and the air heat storage chamber, a first induced draught fan is arranged at the middle portion of the gas return pipe, and a denitration dust removing tower is arranged at the output end of the dust removing box. By meansof the glass factory waste gas denitration method, a selective non-catalytic-reduction denitration method is adopted for conducting denitration on glass kiln waste gas, the treatment cost is reduced,great economic benefits and social benefits are achieved, ammonia gas and NOX are reacted to form N2 and H2O in the environment with the temperature being 850 DEG C to 1100 DEG C, the ammonia gas is sprayed evenly through a spray gun, the NOX can be reacted sufficiently in a mixed reaction space 8, in addition, the reaction speed is high, the denitration effect is good, and therefore the waste gasdischarged into the atmosphere reaches the environment-friendly requirement, the technology is simple, and use and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of exhaust gas purification, and more specifically, the invention relates to a method for denitration of exhaust gas from a glass factory. Background technique [0002] Exhaust gases from glass factories contain some nitrogen oxides (NO X ), under the action of sunlight, it will cause photochemical reactions and form photochemical smog, thus causing serious air pollution. High levels of nitric acid rain, photochemical smog, ozone depletion, and other problems are all related to low levels of NO in the atmosphere X There are relationships. Nitrogen oxide pollution is an important environmental problem. With the development of economy and society, the control standards of nitrogen oxides will gradually become stricter. In order to further reduce the content of nitrogen oxides in the waste gas of the glass factory, it is necessary to carry out denitrification treatment on the waste gas produced by the glass ...
