The disclosure provides a device and method for extracting a clean liquid from a slurry reactor in an environment-friendly and energy-saving manner. The method mainly includes the following steps: S1. siphoning slurry in the slurry reactor into a material collecting pipe, and then spraying the slurry into a settling tank, so that solid particles settle in the settling tank and return to the slurry reactor through a discharging pipe; S2. making supernatant in the settling tank flow upward along a settling pipe, and then flow downward at a pipe intersection into a clear liquid pipe and flow into a clear liquid transition tank; S3. discharging liquid from the clear liquid transition tank in an overflow manner to keep the constant liquid level and a pressure required for siphoning; and S4. introducing gas in the material collecting pipe into an escape pipe and continuously discharging the gas to ensure that the liquid level in the escape pipe is always higher than the pipe intersection so as to ensure that the slurry reactor and the clear liquid transition tank are always communicated and the liquid levels are the same. The device according to the disclosure is simple in structure, and the process is simple, safe and reliable, and is not prone to failure. It is easy to implement large-scale continuous operation and adjust separation efficiency and precision. The device requires low equipment investment and is low in operation cost and environmentally friendly.

A liquid-phase reactor has an outer cylinder and an inner cylinder disposed along an axial direction of the reactor. The outer cylinder has a top head, a straight cylinder section and a bottom head. An annular space is formed between the inner cylinder and the outer cylinder. A top end of the inner cylinder is open and is in communication with the annular space. The inner cylinder has an upper cylinder and a lower cylinder sequentially from top to bottom. The upper cylinder is positioned in the straight cylinder section, with its cross-sectional area being gradually reduced from top to bottom. The lower cylinder is positioned in the bottom head, with its cross-sectional area being gradually increased from top to bottom. An inorganic membrane tube extending along the axial direction of the reactor is provided in the lower cylinder so that a shell-and-tube structure is formed.
