DETAILED DESCRIPTION

[0017] The following is a clear and complete description of the technical solution of the utility model in conjunction with the accompanying drawings of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 3 A modular three-phase separation sedimentation tank is shown, comprising an inclined tube sedimentation zone 1, an inner upper edge of which is provided with a water outlet weir 2, and a plurality of three-phase separation monomers 3, wherein the plurality of three-phase separation monomers 3 are tightly fixed together to form a three-phase separation zone 4, wherein the three-phase separation zone 4 is located directly below the inclined tube sedimentation zone 1, wherein the bottom edge of the inclined tube sedimentation zone 1 abuts against the outer edge of the three-phase separation zone 4, and the inner side of the side wall of the inclined tube sedimentation zone 1 is bent inwardly near the bottom edge to form a baffle 5, wherein the baffle 5 has a flow hole 6 directly opposite to the three-phase separation monomer 3, and the three-phase separation monomer 3 is a bucket-shaped structure with upper and lower openings.

[0019] In this embodiment, the three-phase separation monomer 3 includes a first side plate 7, a second side plate 8, an air baffle plate 9 and a sliding mud ramp plate 10. The first side plate 7, the second side plate 8, the air baffle plate 9 and the sliding mud ramp plate 10 enclose a bucket-shaped structure with upper and lower openings. The sliding mud ramp plate 10 is arranged opposite to the air baffle plate 9. The sliding mud ramp plate 10 protrudes downward from the outlet of the bucket-shaped structure. The end of the air baffle plate 9 is folded outward to form a pipe mouth expansion plate 11. The pipe mouth expansion plate 11 and the sliding mud ramp plate 10 form an expansion pipe mouth 12 below the outlet of the bucket-shaped structure. The sliding mud ramp plates 10 and the air baffle plates 9 located on both sides of the three-phase separation zone 4 are bent vertically upward to form a guide plate 13.

[0020] In this embodiment, the upper edge of the guide plate 13 is higher than the upper edge of the baffle plate 5 .

[0021] In this embodiment, two adjacent three-phase separation units 3 are fixedly connected by bolts.

[0022] In this embodiment, the plurality of three-phase separation units 3 are evenly distributed in a matrix.

[0023] The working principle of this embodiment is as follows.

[0024] Water passes through the bottom of the three-phase separator, and the inverted V-shaped angle formed by the air baffle 9 and the sliding mud ramp 10 blocks the flow and stabilizes the flow. The tiny bubbles in the reaction zone form larger bubbles during the rising process. The bubbles move along the inverted V-shaped angle formed by the air baffle 9 and the sliding mud ramp 10 and are discharged from the V-shaped channel formed by the bucket-shaped module to the reaction zone, realizing gas-liquid separation. The wastewater enters the three-phase separation zone through the flow guide plates 13 on both sides of the modular three-phase separation precipitator through the flow hole 6. After the liquid enters, it passes through the baffle 5, and the gas gathers upward and then returns to the reaction zone to realize gas-liquid separation. In the three-phase separator, due to the high specific gravity of the sludge, the sludge passes downward through the expansion nozzle 12 and slides into the bottom along the sliding mud ramp 10 to realize mud-liquid separation. The separated liquid continues to rise, and the suspended particles are once again intercepted and precipitated into the three-phase separation zone through the inclined tube sedimentation zone. The separated water is discharged through the outlet weir to meet the standards, and finally realizes the efficient separation of mud, gas and water.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
