Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of low-temperature storage tank vent pipes, and specifically relates to a novel low-temperature storage tank vent pipeline. Background Art
[0002] A vent pipe is a device specifically designed to release air or gas from a pipeline. It is used to expel air from the pipeline when it is in operation. During pipeline or equipment maintenance, the vent pipe can be used to release gas from the pipeline to prevent the formation of explosive mixtures. It provides overpressure protection for downstream equipment and allows for the release of high-pressure, high-velocity gases. Flame arresters should be installed on the vent pipe.
[0003] Currently, existing vent piping for cryogenic storage tanks primarily involves adding manual shutoff valves to individual or centralized vent piping. In actual engineering applications, each of these vent piping systems has its own advantages and disadvantages. This vent piping system is simple and easy to understand. When the tank pressure increases and the safety valve trips, the venting condition can be detected promptly, allowing the shutoff valve to be manually opened to discharge gas, reducing the pressure inside the tank and allowing the tank to be restored to a usable state as quickly as possible. However, the disadvantage is that when the safety valve trips, gas is discharged from the tank, resulting in gas loss and indirectly reducing the tank's efficiency. When the tank's operating conditions are highly automated, the tripping of the safety valve will suspend the normal workflow, reducing the degree of automation.
[0004] Therefore, improvements are made to address the above problems. Utility Model Content
[0005] The utility model proposes a novel vent pipeline for low-temperature storage tanks, which solves the problem in related technologies that when the safety valve trips, gas is discharged out of the tank, causing gas loss and indirectly reducing the utilization efficiency of the storage tank.
