Definitions
- the present invention can perform advanced gas-liquid separation such as defoaming and degassing, and can perform washing and clarification.
- the present invention relates to a gas-liquid separation device which is easy to solve and suitable for sanitary specifications.
- devices for performing gas-liquid separation such as defoaming and degassing have been known, including a method of heating or depressurizing a container containing a liquid, a method of using a separation membrane that allows only gas to pass through, and a method of centrifugation. I have.
- heating and decompression systems are mainly batch processes, making continuous processing difficult, and have the disadvantage of taking up a lot of space.
- Separatation membrane systems have clogging when particles or solids are present in the liquid.
- the centrifugal separation method is suitable for continuous processing, and has the advantage that mixed particles and solids do not hinder.
- separation since separation is performed using only the difference in mass between gas and liquid, it can be used as a powerful vacuum device. When connected, the centrifugal separation ability may lose the suction force of the vacuum device, causing the liquid to enter the vacuum device, and there is a problem that it is not easy to strongly extract only the gaseous component.
- a safety device such as a valve mechanism is interposed in the connection passage from the pump-type gas-liquid separation device to the vacuum device, and the pump is started, started, and stopped during the entire process.
- Japanese Patent Application Publication No. WO988Z04833 International application PCT / JP97Z00857, "Self-priming type" Centrifugal pump device ”).
- this invention will be referred to as "Numerical Invention 1".
- the structure of the device of the original invention 1 includes a main pump 51, a sub pump 54, and a vacuum device 57, and the main pump 51 and the sub pump 54
- the central part of the main pump impeller 52 is connected to the auxiliary pump suction port 54a via the central opening of the partition plate 53, and the auxiliary pump discharge port 54b Is connected to the main pump suction port 51a by the recirculation path 54c, the vicinity of the center of the sub-pump impeller 55 is connected to the vacuum device 57 by the exhaust passage 54, and from the start of the pump.
- a slow-acting valve 58 that opens with a delay, a quick-acting valve 59 that closes immediately when the pump stops, and a protection reservoir 60 are interposed in series in the exhaust passage 54f.
- the slow-acting valve 58 is actuated as the hydraulic pressure of the hydraulic fluid of the liquid ring vacuum pump increases. As the internal pressure of the chamber 57 w gradually increases, the valve opens after a certain period of time.
- the device of the original invention 1 prevents liquid intrusion between the pump and the vacuum device over the entire stroke of starting, operating, and stopping the pump, performs fully automatic operation, and is extremely useful in practical use.
- the following unresolved issues remain for some applications. That is, first of all, if it is applied to advanced defoaming and degassing, the gas-liquid separation performance may still be insufficient.
- the equipment normally used for this purpose is of "sanitary type". Not only the wetted surface is finished smoothly, but also the stationary cleaning (internal cleaning without disassembly), disassembly cleaning and reassembly can be easily performed. It is essential that it has a structure.
- the impeller must have a complicated structure including a plurality of impellers 52; 55, a plurality of chambers separated by a partition plate 53, and a large number of casing members. The work is complicated, and the flow path is complicated, so that it is difficult to clean the liquid-contact part without shadow by stationary cleaning.
- the structure of the device of the original invention 2 is such that a gas-liquid separation device is interposed in the flow path of the main pump 71 for sending liquid, and the inlet 7 2a and the outlet 7
- a gas-liquid separation impeller 73 which is rotated by a prime mover 74, is provided in a container 72 of the gas-liquid separation device provided with 2b, and a tail of a tornado-shaped cavity s generated by the rotation.
- a cavity receiver 75 for receiving the bottom and preventing the torn-shaped cavity S from extending and being sucked into the main pump 71 is provided.
- the gap t between the cavity receiver 75 and the inner wall of the container 72 is a flow passage through which only the pumped liquid pressed against the inner wall of the container 72 by the centrifugal force accompanying the rotation of the gas-liquid separation impeller 73 can pass.
- the exhaust pipe ⁇ ⁇ 6 opens near the center of the tornado-shaped cavity s, and the cavity gas is sucked and discharged from the exhaust pipe 76 via the exhaust passage r by the vacuum device 77.
- bubbles in the pumped liquid are forcibly centrifuged by the rotation of the gas-liquid separation impeller 73 different from the impeller of the main pump 71, and the tornado-shaped cavity generated there is generated. s is prevented from extending to the main pump 71 side by extending its tail bottom by the cavity receiver 75, and the liquid rotating against the inner wall of the container 72 preferentially places the gap t. Therefore, there is little possibility that bubbles will escape from the gap t, so that the gas is efficiently collected and sucked and discharged by the vacuum device 77. Therefore, it can be said that the first problem described above, that is, the gas-liquid separation performance, has been almost solved.
- the second problem described above that is, the problem that cleaning is not easy, has not been solved at all. Rather, the presence of the cavity receiver 75 and the gap t provided to improve the gas-liquid separation performance creates new shadows and bottlenecks on the back of the cavity receiver 75 and the exhaust pipe 76 that are difficult to clean. This also has the consequence of causing Due to the bottleneck, clogging may occur in the case of liquids such as liquid foods that contain particles and lumps, so it is difficult to cope with various liquid qualities. Since the cavity is simply suctioned from the opening, it cannot be prevented in the gas-liquid separation device when the formed cavity becomes unstable and the pumped liquid is mixed in. In addition, there is a problem in that the removal of water has to rely on the protective means 78 provided separately.
- the present invention is provided with a gas-liquid separation mechanism that operates stably and reliably with a simple configuration, enables the use of a powerful vacuum device, and performs advanced gas-liquid degassing and degassing.
- a high-performance, easy-to-handle gas-liquid separation device that can perform separation action, and can easily perform stationary cleaning and disassembly cleaning that satisfies sanitary specifications. The purpose is to gain. Disclosure of the invention
