AI Technical Summary
The existing gas injection and discharge pipes of salt cavern gas storage facilities are prone to blockage by mud due to open perforations when inserted into the salt cavern, and mud and sand in the brine can easily enter the discharge pipes, affecting the gas injection and discharge effect.
A brine draining device was designed, comprising a conical seat, a locking component, a limiting component, a perforated plate, and a metal filter screen. Through the locking and unlocking mechanism of the conical seat and the drain pipe, combined with the filtration of the metal filter screen, mud is prevented from entering and silt in the brine is filtered out.
This effectively prevents soil from entering the drainage pipe, ensures smooth gas injection and brine discharge, improves the practicality of the device, and prevents brine pipe blockage.
