A high-temperature industrial flue gas emission desulfurization and denitrification treatment system

Abstract

The invention relates to a high-temperature industrial flue gas emission desulfurization and denitrification treatment system that comprises a pipeline, a flow guide unit, an adjusting unit, treatmentunits and sealing units; the flow guide unit is arranged at the top end of the pipeline, the adjusting unit is arranged on the left side of the pipeline, the adjusting unit is evenly provided with three layers of treatment units from top to bottom, and the sealing units are arranged at the positions where the pipeline makes contact with the treatment units. According to the invention, the following problems existing in desulfurization and denitrification treatment of high-temperature industrial flue gas emission at present can be solved: a, an absorption panel which is arranged in a flue gasexhaust pipeline and is used for absorbing harmful gases such as sulfur dioxide and nitrogen dioxide cannot be replaced in time; and b, the absorption panel is poor in sealing performance and infirm in installation, and when smoke in the smoke exhaust pipeline is exhausted, due to different smoke exhaust amounts, when the smoke reaches the absorption panel, the smoke can be diffused, so that the absorption panel cannot absorb sulfur dioxide and nitrogen dioxide in the smoke in a centralized manner.

Description

technical field [0001] The invention relates to the technical field of industrial flue gas treatment, in particular to a high-temperature industrial flue gas discharge desulfurization and denitrification treatment system. Background technique [0002] The healthy development of human beings is inseparable from a clean environment, and the damage caused by environmental pollution is fatal, so it is urgent to rectify the sources of environmental pollution. When some industries are operating, they will produce a large amount of toxic gases. Once these gases enter the atmosphere, they will quickly destroy the environment we depend on for survival. Therefore, when the high-temperature industrial flue gas is discharged, it is necessary to desulfurize and denitrify the flue gas. Treatment to prevent harmful gases in the flue gas from entering the atmosphere and polluting the environment. [0003] At present, the following problems exist in the desulfurization and denitrification t...

AI Technical Summary

Problems solved by technology

[0003] At present, the following problems exist in the desulfurization and denitrification treatment of high-temperature industrial flue gas emissions: a. The absorption panels placed in the exhaust pipes to absorb harmful gases such as sulfur dioxide and nitrogen dioxide cannot be replaced in time, resulting in absorption The chemicals on the panel used to absorb harmful gases such as sulfur dioxide and nitrogen dioxide have been consumed, and can no longer play the role of absorbing harmful gases such as sulfur dioxide and nitrogen dioxide, so that harmful gases that have not been desulfurized and denitrified enter the atmosphere to pollute the air; b. The installation of the absorption panel is poorly sealed, the installation is not firm, and gas leakage occurs. When the flue gas in the exhaust pipe is discharged, due to the difference in the amount of flue gas discharged, when the flue gas reaches the absorption panel, it will spread. It is inevitable that there will be a small amount of water vapor in the pipe, which will cause the sulfur dioxide and nitrogen dioxide in the flue gas to corrode the inner wall of the pipe when it meets water, so that the absorption panel cannot absorb sulfur dioxide and nitrogen dioxide in the flue gas.
