specific Embodiment approach 1

[0018] see figure 1 , the three-phase separator is installed in the aeration tank 6, the mixed liquid enters the upflow zone 8, and the gas is discharged from the top exhaust pipe 5. Under the action of the density difference between the upflow zone 8 and the downflow zone 9, the mud and water are mixed The liquid enters the downflow zone 9 and returns to the upflow zone 8; at the same time, the mud and water mixture enters the sedimentation zone 7 from the backflow slot 10, and under the action of the pressure difference between the sedimentation zone 7 and the backflow slot area 10, the mud is prevented from entering the sedimentation zone. Zone 7, while the water normally enters the sedimentation zone 7, and finally realizes the three separations of mud, water and gas.

specific Embodiment approach 2

[0020] see figure 2 , In this embodiment, a side deflector 11 is added to the upper assembly, and the others are the same as the first embodiment.

specific Embodiment approach 3

[0022] see image 3 In this embodiment, longitudinal partitions 12 are added to the upper component 1 and the lower component 2, and the others are the same as the first embodiment.

Abstract

The invention discloses a novel three-phase separator, which comprises an upper layer assembly and a lower layer assembly, wherein the upper layer assembly and the lower layer assembly are respectively and additionally provided with vertical flow guide plates, the upper layer assembly is additionally provided with separation plates, and the flow guide plate and the separation plate form a downflowzone. According to the present invention, the novel three-phase separator can achieve well solid-liquid-gas three-phase separation on vigorous turbulent flow mixing solutions, and has a simple structure.

Description

technical field [0001] The invention belongs to a waste water treatment device, in particular to a novel three-item separator. Background technique [0002] In the field of wastewater treatment, the three-phase separator is mainly used in the anaerobic granular sludge process, such as the UASB process, to realize the three-phase separation of mud, water and gas. If the three-item separator used by UASB is installed in the aeration tank, can the three-item separation of mud, water, and gas be realized? After experiments, it was found that the three separations could not be achieved well. Because the aeration tank is aerated by the aeration head installed at the bottom of the tank, the air volume is large and distributed in a dot shape, and the aeration volume of each point is not absolutely the same, so that the mixed liquid in the aeration tank is violent state of turbulent flow. The violent and irregular disturbance of the mixed liquid will be transmitted to the sediment...
