Glass high-temperature kiln flue gas energy conservation and emission reduction purification system and method

Abstract

The invention discloses a glass high-temperature kiln flue gas energy conservation and emission reduction purification system and method. The system comprises a glass kiln, a catalytic reaction tower and an adsorption system which are sequentially connected through flue gas pipelines, and an ammonia adding device is connected to the catalytic reaction tower. The glass high-temperature kiln flue gas energy conservation and emission reduction purification system and method have the advantages that flue gas from the glass kiln needs to be subjected to dedusting treatment, impurities in the flue gas can be prevented from plugging devices and catalysts in subsequent process sections; the flue gas which is too high in temperature can affect normal operation of a dedusting device, and the flue gas which is too low in temperature is not beneficial for subsequent desulfurization and denitrification treatment; according to the technical scheme, the characteristic of the flue gas itself is utilized, heat exchange is conducted on cooled flue gas and high-temperature flue gas, the technological requirement is met, heat energy contained in the flue gas is fully utilized, two adsorption towers are used for secondary adsorption purification in a one in service and one in standby mode, that is to say, one adsorption tower is used for purification treatment, the other adsorption tower is used for regeneration operation, when regeneration operation is conducted, heat energy is provided by the high-temperature flue gas, energy conservation and environment protection are achieved, and the sustainable development requirement is met.

Description

technical field [0001] The invention relates to the technical field of waste purification, in particular to an energy-saving and emission-reducing purification system and purification method for flue gas from a high-temperature glass kiln. Background technique [0002] The glass industry is one of the key industrial pollution control industries in my country. The comprehensive treatment of pollutants in glass kiln flue gas is not only the key to protecting the ecological environment and improving people's quality of life, but also to promote the structural adjustment and sustainable development of my country's glass industry. Sustained development is of great significance. [0003] The treatment method of glass melting furnace exhaust gas is generally similar to the flue gas desulfurization technology of power plants, but the exhaust gas of glass melting kiln also has its particularity, such as high temperature of flue gas, small amount of flue gas, complex pollutant componen...

AI Technical Summary

Problems solved by technology

At present, flue gas desulfurization of glass kilns is still in its infancy, and most of them are simple wet processes that are transplanted from small boiler treatment technology. The technology is immature and not targeted, the system is unstable, and the flue gas treatment effect is not good. Unable to meet the increasingly stringent environmental protection standards, the entire desulfurization and denitrification equipment is severely corroded, scaled, and clogged, the system is not running smoothly, and equipment maintenance costs are high
