As previously indicated, gas-liquid separation liquid cyclones may be used in the food industry such as drinkable beverages. In the food industry, for example, when a certain variety is continuously manufactured, it is necessary to periodically clean the apparatus, and when different varieties are manufactured, it is necessary to clean the apparatus every time the variety changes.
However, in the gas-liquid separation liquid cyclone described in Patent Document 1, since the apparatus has a relatively complicated structure, the cleaning needs to be performed by removing the gas-liquid separation liquid cyclone from the production line, disassembling, and the like. there were.
Such so-called non-stationary cleaning and disassembly cleaning are not preferable because they reduce the operation efficiency of the apparatus and require extra labor.
Further, the gas-liquid separation liquid cyclone has both a liquid outlet (first outlet as described in the present application) and a gas outlet (second outlet as described in the present application). Ingredients are sent out. On the other hand, when the cleaning liquid is sent into the gas-liquid liquid cyclone and cleaning is performed in a stationary manner (while attached to the production line), the liquid component mainly flows through the first outlet side, which is the liquid extraction side. For this reason, the second outlet side may not be sufficiently cleaned.

  Therefore, the object of the present invention has been made in view of the above-mentioned problems, and the object thereof is so-called stationary cleaning, and also in the stationary cleaning, the first outlet side and the second outlet side The object of the present invention is to provide a gas-liquid separation liquid cyclone that can clean both fluid flow paths without excess or deficiency.

In order to achieve the above object, according to the present invention, a liquid inlet that receives a gas-liquid mixed liquid that is a liquid to be treated, and a gas liquid-liquid separated by centrifugal force to separate the gas-liquid mixed liquid into a first liquid mainly. A first characteristic configuration of the gas-liquid separation liquid cyclone having a first outlet for sending out a component and a second outlet for sending out a second component mainly containing a gas component includes a first outlet connected to the downstream side of the first outlet.

The gas-liquid separation liquid cyclone having the first characteristic configuration described above maintains both the first valve and the second valve in the open state during normal operation by the action of the valve control means, and removes the liquid component from the first outlet. A main first component is sent out, and a second component mainly containing a gas component is sent out from the second outlet.
On the other hand, in the cleaning operation state, the cleaning liquid is received in the gas-liquid separation liquid cyclone. In the gas-liquid separation liquid cyclone according to the present application, at least the first valve and the second valve are alternately arranged by the action of the valve control means. The cleaning operation state is realized in which the other valve is opened (the other valve is closed). This alternate open state may be such that both valves are sequentially opened only once (the other valve is closed), or the switching of the valve to be opened is repeated. Also good. In the former case, the part to be cleaned can be reliably cleaned by maintaining the time for maintaining the open state relatively long. On the other hand, in the latter case, it is possible to promote the peeling of dirt by utilizing the pulsation of the cleaning liquid.

It is at a point larger than the minimum diameter c.
By adopting such a structure, the pressure loss generated by the gas-liquid separation liquid cyclone during stationary cleaning controlled in the cleaning operation state does not become larger than during product operation controlled in the normal operation state. Good cleaning can be performed with the upstream side of the hydrocyclone set at the time of product operation.

By adopting such a structure, it is possible to prevent an extreme outflow of liquid from the second outlet during product operation controlled to a normal operation state.
A fourth characteristic configuration of the gas-liquid separation liquid cyclone according to the present invention includes a double cylindrical upper body portion provided with the liquid inlet at a side portion and the second outlet at an upper portion, and a lower cylindrical body connected to the lower body portion. And a lower main body portion having a conical shape provided with the first outlet at a lower portion, and the intersection between the top surface and the inner cylinder in the upper main body portion is formed by a curved surface.
By adopting such a configuration, it is difficult for dirt to collect at the corner of the liquid contact portion (the intersection of the top surface of the upper main body portion and the inner cylinder), and good cleaning can be performed in the stationary cleaning.

The first characteristic configuration of the gas-liquid separation system according to the present invention includes both the first component and the second component sent out from the gas-liquid separation liquid cyclone having any one of the first to fourth characteristic configurations. Equipped with a gas-liquid separation tank to receive,
Only the liquid stored in the gas-liquid separation tank can be taken out.

  The preheating of the processing target liquid a flowing through the second flow path 15b is executed by the heat held by the processing target liquid a that has been processed by the first processing mechanism 101. The preheating of the processing target liquid a flowing through the second flow path 15b is performed in the plate-type heat exchanger 17 at the lowest temperature side heat exchange section 17c.

  The first processing mechanism 101 adopts a configuration in which the processing target liquid a is fed in the order of description through the booster pump 11, the highest temperature side heat exchange part 17 a of the plate heat exchanger 17 and the holding tube 18.

In this way, the sterilized filling target liquid can be sent to the filling machine 3.

Hereinafter, the detailed structure of the gas-liquid separation liquid cyclone 7 according to the present application will be described with reference to FIGS. 1 and 2.
As is well known, the gas-liquid separation liquid cyclone 7 has a liquid inlet 7c for receiving the gas-liquid mixed liquid that is the liquid to be processed a, and gas-liquid separation of the gas-liquid mixed liquid by centrifugal force to separate the liquid component. It comprises a first outlet 7a that sends out a main first component and a second outlet 7b that sends out a second component mainly containing a gas component, and a second outlet 7b on the side of the liquid inlet 7c. An upper main body 71 having a double cylindrical shape provided at the upper part and a conical lower main part 72 connected to the lower main part 71 and having a first outlet 7a at the lower part are configured. .

As shown in FIG. 2A, the liquid inlet 7c guides the processing target liquid a into the upper main body 71 as a jet along the inner wall of the outer cylinder 71a of the upper main body 71 configured as a double pipe. Thus, it is configured as a tapered channel.
In the gas-liquid separation liquid cyclone 7 of the present application, in order to eliminate the site where dirt easily collects so that it can be cleaned in place, R of each part is taken so that the corner of the liquid contact part becomes smooth, The intersection of the top surface of the inner cylinder 71b and the inner wall of the outer cylinder 71a is a curved surface with an R of about 0.5 to 5.0, and the connection part with the connecting device is a connecting part 72x having a ferrule configuration, 71y and 71z.

The main characteristics and dimensions (dimensions) of the gas-liquid separation liquid cyclone 7 will be described.
In a normal operation state in which gas-liquid separation is performed, when a predetermined flow rate is set, the centrifugal effect Z value is 70 or more and the pressure loss is 0.15 MPa or less so that the defoaming effect as a cyclone can be exhibited. Further, the ratio (b / a1) of the length b from the maximum aperture 72max of the lower body 72 to the minimum aperture 72min to the aperture a1 of the outer cylinder 71a of the upper body 71 is 4.0 to 6.0. The ratio (c / a1) of the diameter c of the minimum diameter part 72min of the lower main body 72 to the diameter a1 of the outer cylinder 71a is set to 0.2 to 0.5.
Here, the centrifugal effect Z value is defined as follows.
Z = 2 × u ² / (g × a1)
g is “gravity acceleration”, a1 is “the diameter of the outer cylinder 71a of the upper body 71”, and u is “the flow velocity of the reduced portion of the liquid inlet 7c”.

  Further, as can be seen from FIG. 2, the diameter d of the inner cylinder 71 b located inside the outer cylinder 71 a of the upper body 71 is configured to be larger than the minimum diameter c of the lower body 72, and the upper body D / a1, which is the ratio of the diameter d of the inner cylinder 71b of the upper body 71 to the diameter a1 of the outer cylinder 71a of 71, is 0.5 or less. Specifically, it is about 0.4.

  As shown in FIG. 1, a first valve 74 that can shut off the first connection path 73 is connected to a first connection path 73 connected to the downstream side of the first outlet 7a, and is connected to the downstream side of the second outlet 7b. The second connection path 75 is provided with a second valve 76 that can shut off the second connection path 75. In the normal operation state in which the gas-liquid mixture a is separated from the gas and liquid, in the cleaning operation state in which both the first valve 74 and the second valve 76 are maintained open and the cleaning liquid is received from the liquid inlet 7c. , Valve control means 77 for alternately opening the first valve 74 and the second valve 76 is provided.

  FIG. 3 shows the open / close state of each valve in the normal operation state and the cleaning operation state by the valve control means 77 described above. In the figure, the horizontal axis represents time, and the vertical axis represents the open / closed state of each valve. The top chart shows the timing chart for normal operation, the middle chart shows the timing chart for cleaning operation when cleaning is performed once, and the bottom chart shows the cleaning operation when cleaning is performed multiple times. The timing chart of was shown.

Hereinafter, the operation of the sterilization / filling system 1 described so far will be described.
[Normal operation state]
In this state, the first valve 74 and the second valve 76 described above are always kept open.
[Sterilization and filling operation in normal operation]
The liquid a to be treated is supplied from the preparation tank 4 to the sterilizer balance tank 5 at normal pressure and normal temperature, and is a liquid-liquid heat exchanger of the plate heat exchanger 17 by the liquid feed pump 14 from the sterilizer balance tank 5. A part of the processing target liquid a is supplied to the low temperature side heat exchanging part 17c, preheated, and then enters the booster pump 11.
On the other hand, the processing target liquid a that does not enter the low temperature side heat exchanging portion 17c is sent to the booster pump 11 as it is. The processing target liquid a sent by the booster pump 11 is heated to a temperature exceeding 100 ° C. by the high temperature side heat exchanging portion 17 a, held at the heating temperature for a certain time by the holding tube 18, It is cooled to a cooling temperature of 90 ° C. and is fed to the filling machine 3 side during normal operation.

  Note that hot water or steam is used as the heating medium h in the high temperature side heat exchanging portion 17a, and the heating temperature is adjusted based on the temperature or flow rate of the hot water and the flow rate of the steam.

  Moreover, the processing target liquid a before sterilization sent from the sterilizer balance tank 5 is used as the refrigerant for cooling the processing target liquid a by the temperature lowering mechanism 13, and the processing target liquid a before sterilization is controlled by the control valve 16. The cooling temperature in the temperature lowering mechanism 13 is adjusted by adjusting the ratio of the low temperature side heat exchanging part 17c entering the second flow path 15b.

  When the operation of the sterilization / filling system 1 is started, the aforementioned switching valve 20 is selected on the return flow path 19b side, and the liquid flow rate from the liquid feed pump 14, the heating temperature of the high-temperature side heat exchange unit 17a, and the temperature lowering mechanism Since the cooling temperature of 13 has to be adjusted to be a predetermined condition, the liquid to be treated a is not sent to the filling machine 3 side until it is stabilized in the above state, and the temperature is lowered by the intermediate temperature heat exchanger 17b. And returned to the sterilizer balance tank 5.

  Alternatively, when the liquid supply cushion tank, which is the gas-liquid separation tank 8, becomes full even during normal operation, the liquid to be treated a is not sent to the filling machine 3 side, and the temperature is lowered by the intermediate temperature heat exchanger 17b. And returned to the sterilizer balance tank 5.

  The valve mechanism 6a provided in the feed flow path 19a and the valve mechanism 6b provided in the return flow path 19b are attached because the heating temperature in the high temperature side heat exchange section 17a exceeds 100 ° C., respectively. Therefore, both valve mechanisms 6a and 6b always operate. The pressure of these valve mechanisms 6a and 6b is normally set to 0.2 to 0.3 MPa.

  On the other hand, the liquid to be processed a sent to the filling machine 3 side contains dissolved gas up to a saturated state at room temperature before entering the plate heat exchanger 17, but after coming out to the filling machine 3 side, Because of the temperature of about 90 ° C., it becomes supersaturated and contains many microbubble-like bubbles. The processing target liquid a in this state is sent to the gas-liquid separation liquid cyclone 7, and bubbles including microbubbles are aggregated by the centrifugal effect. From the first outlet 7a below the gas-liquid separation liquid cyclone 7, the first component mainly composed of liquid is sent out, and from the second outlet 7b above, the second component mainly composed of gas is sent out. .

  The first component contains bubbles, but the bubbles continue to wind even after the vortex generated in the gas-liquid separation liquid cyclone 7 exits the lower first outlet 7a. Because of the presence of a valve or the like, it is included in the processing target liquid a as a bubble larger than the microbubble. Therefore, when reaching this position, since the bubbles are not in the form of microbubbles, they are floated on the liquid surface and separated after being supplied to the liquid supply cushion tank 8.

  Further, from the second outlet 7b above the gas-liquid separation liquid cyclone 7, the bubbles aggregated and separated inside the cyclone contain some liquid to be treated a, but to the liquid supply cushion tank 8 in the state of large bubbles. In the same manner, it floats on the liquid surface and is separated.

  In the liquid supply cushion tank, which is the gas-liquid separation tank 8 referred to in the present application, the processing target liquid (this liquid is the filling target liquid) from which bubbles have been separated is supplied to the surge tank 10 by the cushion tank liquid supply pump 9. Is done. The filling target liquid supplied to the surge tank 10 is sent to the filling machine 3.

  The liquid supplied from the surge tank 10 to the filling machine 3 is supplied with aseptic air in the tank in order to maintain a constant supply pressure to each filling valve, regardless of fluctuations in the number of opening of the filling valves provided in the filling machine 3. The liquid is fed at a predetermined pressure.

  Here, in the filling system at the time of product operation (downstream from the valve mechanism 6a), aseptic air is supplied in order to prevent the outside air from being mixed into the liquid to be treated a after sterilization to be contaminated with bacteria. However, if the pressure is high, a problem of pressure loss and a problem that gas-liquid separation cannot be performed occur. Therefore, the inside of the liquid supply cushion tank 8 is set to a slightly pressurized state slightly higher than atmospheric pressure. Yes.

  Furthermore, when the liquid supply pressure to the filling machine 3 side exceeds the set pressure of the valve mechanism 6a, there is a difference in the liquid supply pressure between the case of sending the liquid to the filling machine 3 side and the case of returning to the sterilizer balance tank 5. The liquid flow rate changes when switching between the return to the sterilizer balance tank 5 and the liquid feeding to the filling machine 3 side occurs, the heating temperature in the high temperature side heat exchanging part 17a and the cooling temperature in the temperature lowering mechanism 13 There is a control problem that is deviated from the set value.

  Therefore, if the pressure loss of the gas-liquid separation liquid cyclone 7 exceeds the set pressure of the valve mechanism 6a, the above-described operational control problems occur on the upstream side of the valve mechanism 6a. The sum of the pressure loss and the pressure of the liquid supply cushion tank is set to be lower than the set pressure of the valve mechanism 6a.

[Washing operation state]
In this state, the first valve 74 and the second valve 76 are controlled to open and close according to the middle or lower timing chart of FIG.
Furthermore, the cleaning liquid is introduced into the sterilization / filling system 1 from the cleaning liquid introduction unit 80 shown in FIG. 1, and the entire system can be cleaned satisfactorily. In this cleaning operation state, the entire cleaning liquid flows to the valve side maintained in the open state according to the open / closed state of the first valve 74 and the second valve 76, and exhibits a cleaning effect.

[Another embodiment]
In the above embodiment, the gas-liquid separation liquid cyclone 7 according to the present application and the gas-liquid separation system configured by combining the gas-liquid separation liquid cyclone 7 and the gas-liquid separation tank 8 are employed in the sterilization / filling system 1. Although the example was shown, the gas-liquid separation liquid cyclone 7 which concerns on this application is also employable for the preparation system 200 which performs preparation of a drink, for example.
An example of such a blending system 200 is shown in FIG. In this example, mixing is performed in the mixer 201, and the system is configured by the gas-liquid separation liquid cyclone 7 and the preparation tank 202 according to the present application.
In this example as well, the first valve 74 and the second valve 76 and the valve control means 77 for controlling the opening and closing of these valves are alternately controlled to open and close the valves in the stationary cleaning state (in the equipment system). You can do it with the equipment).

  It was possible to provide a gas-liquid separation liquid cyclone capable of performing cleaning in place and cleaning the fluid flow paths on both the first outlet side and the second outlet side without excess or deficiency.
