METHOD AND APPARATUS FOR EXTRACTING CLEAN LIQUID FROM SLURRY REACTOR

WIPO Patent Application WO/2022/040844

A1

An apparatus and method for extracting clean liquid from a slurry reactor (3-1) in an environment-friendly and energy-saving mode. The method comprises the following steps: S1, slurry in the slurry reactor (3-1) is siphoned into a material collecting pipe (4) and then sprayed into a settling tank (6), and solid particles settle in the settling tank (6) and return to the slurry reactor (3-1) by means of a discharging pipe (5); S2, a supernatant in the settling tank (6) flows upwards along a settling pipe (16), flows downwards into a clear liquid pipe (8) at an intersection of pipes and flows into a clear liquid transition tank (9); S3, the clear liquid transition tank (9) drains liquid in an overflow mode, such that the constant liquid level and the pressure required by siphoning are maintained; and S4, gas in the material collecting pipe (4) enters a gas escape pipe (11) and is continuously exhausted, such that the liquid level in the gas escape pipe (11) is always higher than the intersection of pipes to ensure that the slurry reactor (3-1) is always communicated with the clear liquid transition tank (9), and the liquid level is kept identical. The apparatus is simple in structure, simple in technological process, safe and reliable, not prone to failure, easy to achieve large-scale continuous operation, easy to adjust separation efficiency and precision, small in device investment, low in operation cost, and environmentally friendly.
