Glass kiln desulfurization and denitration tower

Abstract

The invention belongs to the technical field of flue gas purification, and particularly relates to a glass kiln desulfurization and denitration tower, which comprises a tower body; a first gas inlet is formed in the bottom of the left side wall of the tower body; the bottom of the tower body is fixedly connected with a first partition plate; a gas storage tank is formed in the first partition plate; a gas storage port is formed in the first partition plate; the gas storage port is matched with the first gas inlet and is communicated with the space in the gas storage tank; the energy consumption is low, the temperature of high-temperature flue gas is reasonably utilized to volatilize ammonia water, the inner wall can be automatically cleaned after the high-temperature flue gas is introduced, and residual ammonia gas is absorbed; meanwhile, the denitration and desulfurization efficiency is accurately controlled, the influence of dust particles and reaction liquid in the high-temperature flue gas on the denitration and desulfurization reaction can be treated in time, and the stable proceeding of the denitration and desulfurization reaction is ensured all the time.

Description

Technical field [0001] The present invention belongs to the field of flue gas purification, and is specifically a glass cellar desulfurization denitrite. Background technique [0002] Glass industrial melting kiliers flue gas desulfurization, dust removal and denitration are environmental protection policies that have been put forward and proposed in the country in recent years, which aims to protect the environment, inhibit the overcapacity of industry, and promote industry technology transformation. [0003] At present, traditional glass kiln flue gas desulfurization techniques include two categories of dry and wet method, mainly CFB circulating fluidized bed smoke desulfurization technology and NID flue gas desulfurization technology, the main principle is to use powdered or granular absorbers, adsorption The agent or catalyst to remove SO2 in the flue gas, the desulfurization efficiency of the technology itself can reach 70% to 90%, and the two techniques themselves still hav...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the relatively large energy consumption of the existing technology device, the high-temperature characteristics of the high-temperature flue gas itself cannot be reasonably used, and the interior of the device is not automatically cleaned after the work is completed, resulting in the residual ammonia gas in the device not being collected in time. Insufficient: solve the problem of not being able to make reasonable use of the high-temperature characteristics of the high-temperature flue gas itself, and at the same time, in the process of denitrification and desulfurization, the efficiency of denitrification and desulfurization is not controlled more accurately, and the dust particles and reaction liquid in the exhaust gas cannot be processed in a timely manner The impact on the denitrification and desulfurization reaction cannot ensure the smooth progress of the denitrification and desulfurization reaction at all times, and the effect of long-term use is not ideal. A glass furnace desulfurization and denitrification tower proposed by the present invention
