Denitration of glass kiln waste gas by utilizing heat accumulation chamber of glass kiln

Abstract

The invention provides denitration of glass kiln waste gas by utilizing a heat accumulation chamber of a glass kiln and belongs to the field of environment protection. In a glass industry, an SCR (Selective Catalytic Reduction) method is commonly used for carrying out the denitration; in the SCR method, ammonia escapes to cause secondary pollution. The invention does not utilize ammonia water, sothat the secondary pollution is not caused. The denitration is carried out on the glass kiln waste gas by utilizing the heat accumulation chamber of the glass kiln. A denitration catalyst is processedon the surface of a heat accumulation body with certain temperature in the heat accumulation chamber of the glass kiln; when the glass kiln waste gas passes through the heat accumulation chamber, NOand NO2 in the waste gas generated by the glass kiln are removed. An atomizing method is used for uniformly processing the catalyst on the surface of the heat accumulation body and the inner surface of the heat accumulation chamber of the kiln which is operated normally. A fireproof material for a region with the temperature of 700 DEG C or lower of a newly built kiln is immersed and sprayed or the denitration catalyst is micro-sintered on the surface of the heat accumulation body, so that the denitration aim can be realized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection. Specifically, the regenerator of the glass kiln regenerator is used as the carrier of the denitration catalyst, and the surface of the regenerator of the glass kiln is coated, dipped, and processed with the denitrification catalyst to achieve a glass kiln. The purpose of furnace flue gas and waste gas denitrification. The characteristic of this technology is that the purpose of denitrification can be achieved without using the SCR method. It does not add auxiliary equipment, does not increase additional power consumption, does not use ammonia water, has very little operating cost, and has no ammonia escape, which belongs to green environmental protection technology. Background technique [0002] With the improvement of national air emission standards, the waste gas produced by the combustion of glass kiln fuel must be desulfurized, denitrified, and dust-removed before it can be ...
