How can pressure be released quickly from a DN100 carbon steel pipe used for intermittent backwashing with compressed air?

If rapid pressure relief is required, a quick-release valve or solenoid valve and other devices can be installed on the pipeline to achieve this. Additionally, pressure release can also be achieved by manually opening the vent valve. It should be noted, however, that appropriate safety procedures must be followed during pressure relief operations to ensure the safety of the operators. As for whether adding a DN500 pipe section in the pipeline is effective, it depends on the specific circumstances. If this pipe can effectively increase the ventilation capacity of the piping system and reduce the pressure inside the pipes, it can play a certain role. However, it is necessary to determine whether additional pipes are needed, as well as parameters such as the size and location of the pipes, based on the design and operating conditions of the specific pipeline. .

It seems to be a topic that falls outside the scope of design. For rapid pressure relief, a comprehensive consideration is necessary. Such as restricting the pressure relief time to prevent material agitation and damage to the internal structure. Not all pressure release requires it to occur in the shortest possible time; otherwise, it would be a catastrophic pressure release. If speed is the only requirement, factors such as the diameter of the pressure relief valve and the pipeline resistance downstream of the valve need to be considered. For reference.
