Abstract

The invention provides a glass kiln flue gas treatment method, which comprises the following steps: first-stage waste heat recovery: recovering waste heat of glass kiln flue gas through a first-stageheat exchanger; dry modulation: adding excessive alkaline powder into the glass kiln flue gas subjected to primary waste heat recovery according to the content of sulfur dioxide in the glass kiln fluegas; ceramic membrane catalysis: carrying out catalytic treatment on the glass kiln flue gas modulated by a dry method through a ceramic membrane catalytic filter tube under an alkaline condition soas to obtain treated dischargeable glass kiln flue gas; and catalytic treatment: obtaining treated glass furnace flue gas; wherein the ceramic membrane catalytic filter pipe comprises a ceramic filterlayer and a catalytic layer, the catalytic layer comprises an active component, a carrier catalysis assisting component and a mechanical stabilizing component, and the catalyst is uniformly distributed in the ceramic filter layer. The invention further provides a glass kiln flue gas treatment system.

Description

technical field [0001] The invention relates to the field of environmental protection technology, in particular to a method and system for treating flue gas from a glass kiln. Background technique [0002] In the glass production process, due to the addition of Glauber's salt and soda ash, the composition of the flue gas is very complex, which affects denitrification, desulfurization and dust removal. The glass kiln is changed every 15-20 minutes. During the process of changing the fire, the content of sulfur dioxide, smoke and nitrogen oxides will change drastically. In the process of glass production, the stability of the kiln pressure is very important. It is installed at the tail of the furnace flue gas. With the continuous improvement of flue gas emission standards for glass melting furnaces and the continuous introduction of strict control and monitoring measures for air pollutant emissions in various regions of the country, ultra-low emission standards are imperative...
