This invention discloses a high-pressure gas-liquid separation and return device, comprising a first high-pressure tank and a second high-pressure tank. The first high-pressure tank has an inlet
pipe at its top, extending to its bottom. Inside the first high-pressure tank, from top to bottom, are arranged a three-stage gradient sintered
filter element, a baffle plate, and a flow deflector. The upper part of the first high-pressure tank is connected to the second high-pressure tank via a gas
pipe. The second high-pressure tank has a
fiber filter surface, an outlet at its top, and a liquid return port at its bottom. This device has a compact structure, can operate efficiently under
high pressure, exhibits excellent separation efficiency, significantly reduces liquid entrainment, and meets the high-pressure gas-liquid separation requirements of many fields such as
chemical engineering and energy.
