Abstract

The invention discloses an integrated device for flue gas denitrification, deboration and dust removal in an ultra-thin float glass substrate production line. The integrated device comprises a lime storing-transporting unit, a heat exchange cooling part, a deboration part, an ammonia water spraying part, a catalyst filtering part and a by-product collecting part, wherein flue gas and slaked lime enter the deboration part together to be deborated after fully reacted, then flue gas of mixed ammonia water is denitrated by the catalyst filtering part, and the lime storing-transporting unit, the heat exchange cooling part, the deboration part, the ammonia water spraying part and the catalyst filtering part are cooperated with the by-product collecting part mutually, so that the flue gas is deborated and denitrated; and the flue gas can be further purified by a catalyst filter dust collector, therefore, emissions of the flue gas meet emission standards.

Description

technical field [0001] The invention relates to the field of flue gas treatment of glass melting furnaces, in particular to an integrated device for flue gas denitration, deboronization, and dust removal for an ultra-thin float glass substrate production line. Background technique [0002] In 2017, the revision list (draft for comments) of the "Flat Glass Industry Air Pollutant Emission Standard" (GB 26453-2011) was issued. In areas where the environment is fragile and prone to serious atmospheric pollution problems that require special protection measures, the pollution discharge behavior of enterprises should be strictly controlled. It also stipulates that enterprises in the above-mentioned areas implement special emission limits for air pollutants as follows: [0003] Glass melting furnace particle limit 20mg / m 3 , sulfur dioxide limit 100mg / m 3 , NOx limit 400mg / m 3 . [0004] At the same time, in June 2017, the "Technical Specifications for Ultra-Low Emission Flue ...
