Through the setting of the pressure relief exhaust cylinder 8, a plurality of groups of pressure relief exhaust cylinders 8 are equidistantly arranged on the surface of the separation tower body 1, so that the air pressure at different positions in the tower can be detected in time, and the accuracy of data detection can be increased. The air pressure detection probe 806 is aimed at the interior of the inner tower 4, and the internal air pressure can be detected, which is conducive to timely exhaust and pressure relief of the air pressure inside the separation tower, and prevents the pressure value from being too high, causing extrusion damage to the shell of the inner tower 4. The setting of the guide piece 805 allows the gas to be discharged spirally outward, and avoids the gas discharge speed being too fast, causing the air pressure value to change too much, and causing the internal air pressure to be unstable;

[0024] A float valve 9 is embedded and installed on the surface of the tower plate 7, a pressure ring 901 is provided at the bottom of the upper end of the float valve 9, and spring latch pieces 902 are provided on the edge surfaces of both sides of the lower end of the float valve 9, and an airway 903 is opened on the surface of the spring latch piece 902, the diameter of the pressure ring 901 is larger than the aperture of the circular hole on the surface of the tower plate 7, and the spring latch piece 902 is arranged in an arc shape between the lower end of the float valve 9 and the lower surface of the tower plate 7. The arrangement of the float valve 9 is conducive to the upward discharge of gas, and the arrangement of the pressure ring 901 can clamp the float valve 9 in the circular hole on the surface of the tower plate 7 to prevent the float valve 9 from sinking into the circular hole and causing the float valve 9 to be stuck, and the lower edge area of ​​the float valve 9 is extended to prevent the float valve 9 from falling off from the circular hole.

[0025] Working principle: For this type of filtering separation tower, first, the medium is allowed to enter the inner tower 4 inside the separation tower body 1 through the feed port 3, and the medium will flow on the internal tower plate 7. As the medium continues to enter, the water level gradually increases, and the medium will overflow the overflow weir 10 and enter the interior of the downcomer 11. At the same time, after the bottom of the separation tower is heated, the gas is discharged from bottom to top. After the float valve 9 on the surface of the tower plate 7 floats upward, the spring clip 902 will abut between the lower end of the float valve 9 and the lower surface of the tower plate 7 to prevent the float valve 9 from falling off from the circular hole of the tower plate 7, and the gas will flow out through the gap after the float valve 9 floats. Secondly, the air pressure detection probe 806 is aligned with the air pressure detection model MH7100 located inside the inner tower 4. The instrument 14 will cooperate with the air pressure detection probe 806 to detect the internal air pressure in the tower. The air pressure detection instrument 14, the air pressure detection probe 806 and the air pressure sensor of model HM30 cooperate with each other to form an air pressure detection device. When the air pressure value in the tower is too high, the mini hydraulic cylinder 804 of model CJPB6 will drive the sealing plug 803 to leave the air port 802, and the gas will be discharged outward along the guide plate 805 spiral, and the air pressure inside the separation tower will be exhausted and depressurized in time to prevent the pressure value from being too high and causing extrusion damage to the shell of the inner tower 4. After the air pressure value is normal, the sealing plug 803 will be blocked back into the air port 802 to keep the air pressure in the tower stable, thus completing the entire use process of the filtering separation tower.
