Device and method for reducing sulfur dioxide of chimney of dry quenching environment ground dust removal system

Abstract

The invention provides a device and method for reducing sulfur dioxide of a chimney of a dry quenching environment ground dust removal system. The device comprises a first automatic valve, a second automatic valve, a third automatic valve, a dust removal station, a variable-frequency fan, a smoke gas desulfurization device and an automatic control system, wherein the first automatic valve and thesecond automatic valve are arranged onto a pre-storing chamber discharging pipeline between a sub coal saver and a dust removal negative pressure pipeline; a tee joint is also arranged on the pre-storing chamber discharging pipeline between the first automatic valve and the second automatic valve; the tee joint is connected with the dust removal station through the third automatic valve via a pipeline; the dust removal station is connected with the smoke gas desulfurization device through a pipeline; the variable-frequency fan is positioned onto a pipeline between the dust removal station andthe smoke gas desulfurization device; the automatic control system is electrically connected with the first automatic valve, the second automatic valve, the third automatic valve and the variable-frequency fan. The device and the method mainly solve the problem of sulfur dioxide standard exceeding of the chimney of a dry quenching environment ground dust removal station; the pollutant discharge can be further reduced.

Description

technical field [0001] The invention relates to a device and method for reducing sulfur dioxide in a chimney of a ground dust removal system in a CDQ environment, and belongs to the technical field of CDQ production. Background technique [0002] Dry coke quenching is relative to wet coke quenching, which refers to the substance obtained by cooling red coke with an inert gas (usually nitrogen). CDQ has many advantages, such as absorbing the heat of red coke to save energy; improving the quality of coke; improving the environment and reducing pollution. The process of preparing dry coke quenching prevents the pollution of the atmospheric environment by harmful components such as water vapor, phenol, sulfide, and cyanide produced by wet coke quenching. In order to make the CDQ system achieve the purpose of energy saving and environmental protection, it is necessary to purify the particulate matter generated in the production process. Therefore, a special dust removal system i...
