Glass-furnace-smoke integrated-denitration-desulfurization-dedusting technological device and technology

Abstract

The invention belongs to the technical field of smoke purifying, and provides a glass-furnace-smoke integrated-denitration-desulfurization-dedusting technological device and a technology. A waste-heat boiler (2) of the glass-furnace-smoke synchronous denitration-desulfurization-dedusting technological device is internally and sequentially provided with a primary heat exchanger (7), a medium-temperature denitration reactor (8), a secondary heat exchanger (9) and a multistage heat exchanger (10) from front to back in the smoke flow direction; a low-temperature denitration-desulfurization-dedusting reacting tower (3) comprises a tower body divided into a main tower body (11) and an auxiliary tower body (12); a reducing agent evaporator (13) is arranged in a smoke inlet in one side of the main tower body (11); a low-temperature catalysis reacting bed (20) is arranged in the auxiliary tower body (12). By means of the glass-furnace-smoke integrated-denitration-desulfurization-dedusting technological device and the technology, the one-time investment cost and the occupied area are saved, and meanwhile the operating cost is reduced; and the aims of clean governance and zero release are achieved as a whole.

Description

technical field [0001] The invention belongs to the technical field of flue gas purification, and in particular relates to an integrated denitrification, desulfurization, and dust removal process equipment and technology for glass kiln flue gas. Background technique [0002] Flue gas desulfurization, dust removal and denitrification of furnaces in the glass industry are environmental protection policies proposed and promoted by the state in recent years, aiming at protecting the environment, curbing excess capacity in the industry, and promoting technological transformation in the industry. [0003] At present, traditional glass kiln flue gas desulfurization technology includes dry method (including semi-dry method) and wet method, mainly including CFB circulating fluidized bed flue gas desulfurization technology and NID flue gas desulfurization technology. Or granular absorbent, adsorbent or catalyst to remove SO from flue gas 2 , the desulfurization efficiency of the tech...

AI Technical Summary

Problems solved by technology

[0006] For the flue gas treatment of glass furnaces, there is currently no combined technology in China that can realize the simultaneous removal of nitrogen oxides, sulfur dioxide and dust in the flue gas, and can also be organically connected with the waste heat recovery boiler supporting the glass furnace For this reason, the present invention proposes a glass kiln flue gas synchronous denitrification, desulfurization and dust removal technology, which has passed the Chinese standard and is being industrialized
