Embodiment Construction

[0009] The specific implementation of the present invention is described below in conjunction with accompanying drawing:

[0010] like figure 1 As shown, the flow of the integrated method of waste heat power generation and denitrification in glass kiln is as follows: the temperature of the flue gas from the glass kiln passes through the waste heat boiler, and then the temperature drops to 320-370 degrees, and then the flue gas passes through the medium temperature denitrification reaction device at a flow rate of 4-6m / s flue gas NO X denitrification reduction, the catalytic reaction temperature of medium temperature denitrification in this section is: 300-400 degrees, and the catalyst used in the reaction is a flat-plate catalyst V 2 o 5 / TiO 2 , The board spacing is 5-6mm. The reducing agent is liquid ammonia, and then the temperature is reduced to 150-200 degrees in the evaporation section of the waste heat boiler, then the bag dust is removed, and finally it is discharg...

Abstract

The invention provides a power-generation and denitrification integrated device by residual heat of a glass furnace and a method thereof, relating to the field of waste gas chemical purification treatment. Regarding NOX in large-output volume continuous flue gas in flat glass industry, SCR and SNCR technologies are adopted currently. SCR has the problems of large equipment investment, high technical difficulty, residual heat waste and the like, while SNCR has a large NH3 usage amount, is hard to ensure reacting temperature and staying time, can easily cause secondary pollution, and has low denitrification efficiency. Aiming at the problems and being different from hot topic studying directions, such as high-performance low-temperature denitrification catalyst, additive and the like, the invention discloses the power-generation and denitrification integrated device by the residual heat of the glass furnace and the method thereof, wherein a denitrification system is arranged between the overheat section and an evaporation section of the residual heat boiler; the temperature of the flue gas is cooled to a medium temperature range by using the overheat section of the primary residual heat boiler; and the flue gas performs a catalytic reduction with a reducing agent NH3 in a reactor under the action of a catalyst V2O5/TiO2 to generate non-polluted N2 and H2O, and the temperature of denitrification and catalysis is between 300 and 400 DEG C.

Description

technical field [0001] The invention relates to the field of chemical purification treatment of waste gas, in particular to an integrated device and method for denitration of nitrogen oxides in waste gas of a glass kiln and utilization of waste heat. Background technique [0002] The flat glass industry is an important material industry that is indispensable for the development of my country's national economy and the improvement of people's living standards. The flat glass industry is also one of the industries that emit more serious air pollutants. The pollutants emitted mainly include dust, NO X , SO 2 And and a small amount of HF, HCL. Among them, SO 2 and a small amount of HF and HCL are generally removed by wet and dry desulfurization technology, while the current large-capacity continuous flue gas NO X Generally, selective catalytic reduction denitration technology (Selective Catalytic Reduction, SCR) and selective non-catalytic reduction denitration technology (S...
