Abstract

The invention provides a gas supply device and method for a dry gas sealing system. The gas supply device for the dry gas sealing system comprises a gas supply module and a monitoring module, the gassupply module comprises a gas supply pipeline and a pressure control structure arranged on the gas supply pipeline, and the pressure control structure is used for controlling the pressure of isolatinggas in the gas supply pipeline, the gas supply module communicates with the dry gas sealing system arranged on a compressor unit through the monitoring module, and the monitoring module comprises a flow displaying device used for displaying the flow of the isolating gas, wherein when the flow displaying value of the flow displaying device is greater than or equal to a preset flow value, a controlsystem of the compressor unit controls a lubricating oil pump body to be started. The problem that in the prior art, a worker difficultly judges whether the isolating gas is put into use normally ornot is effectively solved.

Description

technical field [0001] The invention relates to the technical field of coal chemical industry, in particular to a gas supply device and a gas supply method for a dry gas sealing system. Background technique [0002] At present, during the start-up and operation of the compressor unit, only when the gas pressure of the isolation gas in the dry gas sealing system reaches the preset pressure value, that is, the isolation gas is normally put into use, can the lubricating oil pump body be started to prevent the lubricating oil from entering into the The sealing end face of the dry gas sealing system is damaged. [0003] However, in the prior art, there is no special equipment to judge the circulation state of the isolation gas in the dry gas sealing system, which makes it difficult for the staff to judge whether the isolation gas is normally put into use, thereby increasing the operational difficulty and Labor intensity. Contents of the invention [0004] The main purpose of ...
