Abstract
Description
Technical Field
[0001] This utility model relates to the field of three-phase disc separator technology, specifically to a liquid discharge device for a three-phase disc separator. Background Technology
[0002] The three-phase disc separator is mainly used for separating two immiscible liquids and a small amount of impurities. The materials to be separated are fed into the rotating drum. Under strong centrifugal force, the materials pass through the separation intervals of a set of discs. Heavy residues accumulate in the sedimentation zone and are periodically discharged. The oil and water phases are separated by the neutral pores of the discs. The water phase moves outward along the disc wall and flows upward to the centripetal pump for output, while the oil phase moves inward along the disc wall and converges at the lower centripetal pump for output. The basic working principle can be found in the utility model patent disclosed in authorization announcement number CN203816789U, which describes a three-phase disc separator.
[0003] The three-phase disc separator operates at high speeds during startup and operation, which generates vibrations. It also requires high separation efficiency between the water and oil phases. If the oil phase pipeline is not cleaned in time after shutdown, a lot of oil sludge will accumulate, which is not conducive to the next operation and separation of the equipment. Utility Model Content
[0004] The purpose of this invention is to provide a liquid discharge device for a three-phase disc separator, which improves the timeliness and convenience of cleaning the oil phase pipeline.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] The liquid outlet device of the three-phase disc separator includes a water phase pipe and an oil phase pipe. One end of the water phase pipe is connected to the water phase outlet of the three-phase disc separator, and a water phase pressure gauge and a water phase outlet valve are connected to the water phase pipe. One end of the oil phase pipe is connected to the oil phase outlet of the three-phase disc separator, and an oil phase pressure gauge and an oil phase outlet valve are connected to the oil phase pipe. A flushing pipe is provided between the water phase pipe and the oil phase pipe, and a flushing valve is provided on the flushing pipe.
[0007] Furthermore, one end of the water phase pipe and one end of the oil phase pipe are both made of flexible tubing.
[0008] Furthermore, a water phase sight glass is connected between one end of the water phase pipeline and the water phase pressure gauge; an oil phase sight glass is also connected between one end of the oil phase pipeline and the oil phase pressure gauge.
[0009] Furthermore, the water phase sight glass and oil phase sight glass are pipeline sight glasses.
[0010] Furthermore, a connection point between the water phase outlet valve and the water phase pressure gauge is defined as the first connection point, and a connection point between the oil phase outlet valve and the oil phase pressure gauge is defined as the second connection point. The two ends of the flushing pipe are respectively connected to the first connection point and the second connection point.
[0011] Furthermore, when the aqueous phase outlet valve is closed, the oil phase outlet valve is open, and the flushing valve is open, the flushing fluid in the aqueous phase pipeline can be used to clean the oil phase pipeline.
[0012] The beneficial effects of this utility model are:
[0013] (1) After the three-phase disc separator is running, the solid phase is discharged from the slag outlet. By observing the water phase sight glass, water phase pressure gauge, oil phase sight glass, and oil phase pressure gauge, the water phase outlet valve and oil phase outlet valve are adjusted to achieve the ideal separation effect. After separation is completed, the water phase outlet valve is closed, the oil phase outlet valve is opened, and the flushing valve is opened. The flushing liquid in the water phase pipeline can flow to the oil phase pipeline to clean it, preventing the oil phase from scaling in the pipeline. Timely cleaning ensures the normal operation and good separation function of the equipment in subsequent use.
[0014] (2) Flexible hoses, such as corrugated pipes, are used at one end of the water phase pipeline and one end of the oil phase pipeline to reduce pipeline vibration during equipment operation. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.
[0018] Embodiments of this utility model:
[0019] like Figure 1As shown, the liquid outlet device of the three-phase disc separator includes an aqueous phase pipe 1 and an oil phase pipe 2. One end of the aqueous phase pipe 1 is connected to the aqueous phase outlet of the three-phase disc separator, and one end of the oil phase pipe 2 is connected to the oil phase outlet of the three-phase disc separator. The three-phase disc separator has three-phase outlets: aqueous phase, oil phase, and solid phase. The solid phase is discharged from the slag outlet, while the aqueous phase and oil phase are discharged from the aqueous phase outlet and oil phase outlet, respectively, and enter their respective pipes. The multiphase separation principle of the three-phase disc separator is existing technology and will not be elaborated further.
[0020] One end of the water phase pipeline 1 and one end of the oil phase pipeline 2 are both made of flexible hoses, such as corrugated pipes, to reduce pipeline vibration during equipment operation. The flexible hoses are referred to as the first flexible hose 11 and the second flexible hose 21, respectively.
[0021] A water phase pressure gauge 4 and a water phase outlet valve 5 are connected to the water phase pipeline 1; an oil phase pressure gauge 7 and an oil phase outlet valve 8 are connected to the oil phase pipeline 2. Each pressure gauge is used to detect and display the pressure in its respective pipeline to determine the liquid flow state. The water phase outlet valve 5 and the oil phase outlet valve 8 are proportional control valves that can adjust the flow rate.
[0022] A water phase sight glass 3 is connected between one end of the water phase pipe 1 and the water phase pressure gauge 4; an oil phase sight glass 6 is connected between one end of the oil phase pipe 2 and the oil phase pressure gauge 7. The water phase sight glass 3 and the oil phase sight glass 6 are pipe sight glasses connected to the corresponding pipes. These pipe sight glasses are existing technology and have transparent windows, allowing the liquid flow in the pipes to be seen directly from the outside.
[0023] A flushing pipe is provided between the aqueous phase pipe 1 and the oil phase pipe 2, and a flushing valve 9 is provided on the flushing pipe. The flushing valve 9 can be a shut-off valve or a check valve, with the check valve allowing the flushing fluid to flow in one direction only. To facilitate understanding of the location of the flushing pipe: the connection point between the aqueous phase outlet valve 5 and the aqueous phase pressure gauge 4 is defined as the first connection point, and the connection point between the oil phase outlet valve 8 and the oil phase pressure gauge 7 is defined as the second connection point. The two ends of the flushing pipe are connected to the first connection point and the second connection point, respectively.
[0024] After the three-phase disc separator is running, the solid phase is discharged from the slag outlet. By observing the water phase sight glass 3, water phase pressure gauge 4, oil phase sight glass 6, and oil phase pressure gauge 7, and adjusting the water phase outlet valve 5 and oil phase outlet valve 8, the ideal separation effect can be achieved.
[0025] After separation is complete, close the aqueous phase outlet valve 5, open the oil phase outlet valve 8, and open the flushing valve 9. The flushing fluid in the aqueous phase pipeline 1 can be used to clean the oil phase pipeline 2. The flushing fluid can be hot water, etc. The equipment enters hot water from the feed inlet for cleaning, allowing the hot water in the aqueous phase pipeline 1 to flush the oil phase outlet pipeline, thus preventing the oil phase from scaling in the pipeline.
