DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas-liquid surplus separation type gas-liquid pressure reactor for reacting a gas and a liquid under pressure or supplying a gas solution in which the gas is supersaturated and dissolved. .

[0002]

2. Description of the Related Art Conventionally, as a method of reacting a gas with a liquid or dissolving a gas into a liquid, a liquid to be dissolved or the like is accommodated in a pressurized tank, and a large amount of gas is sent into the liquid. The gas-liquid reaction and the dissolution of gas have been performed in the pressurized tank. When the gas-dissolved liquid is pumped or sprinkled, the gas-dissolved liquid is sent to a pump for pumping.

[0003]

In the prior art described above, in the conventional pressurized reaction apparatus, a pump is used when pumping the liquid to the reaction apparatus, and once when the excess gas is separated after the dissolution reaction. Since it is necessary to reduce the pressure to the atmospheric pressure, another pump must be used even when the liquid is pumped and sprinkled, and there is a problem that the apparatus becomes complicated and large. Furthermore, the material of the pump used after the gas dissolution reaction is limited by the properties of the liquid in which the gas has been dissolved and reacted, and there is a problem that the pump material is expensive or difficult to obtain.

The present invention has been made in view of the above-mentioned problems of the prior art, and when pumping a liquid in which a gas has been dissolved or reacted with a gas, the gas dissolved liquid can be easily and reliably provided without using a pump. Alternatively, it is another object of the present invention to provide an excess gas separation type gas-liquid pressurized reaction apparatus which enables the processing liquid after the reaction to be pumped.

On the downstream side of the
A gasket is formed in the gas inflow section,

On the downstream side, a gas separation flow path that protrudes upward on the downstream side of the flow path and branches off from the main flow path is formed, and a liquid surface of the liquid flowing into the gas separation flow path at a predetermined position of the gas separation flow path is formed. A surplus gas separation type in which a sensor to be detected is attached, a restrictor is provided at the tip end side of the gas separation flow path and an electromagnetic valve that is opened and closed by a detection signal of the sensor, and a restriction nozzle is provided downstream of the branch point in the main flow path. It is a gas-liquid pressurized reactor.

[0006]

According to the surplus gas separation type gas-liquid pressurized reactor of the present invention, a flow path is formed in a stepwise manner from top to bottom while gradually increasing and decreasing, and a gas-liquid mixed flow is caused to flow through this flow path. In the passage, gas flows in the upper part of the flow path and liquid flows in the lower part of the flow path, and a flow having a large gas-liquid contact area can be obtained. And by providing a throttle at the outlet of the flow path that flows down stepwise from top to bottom while repeating the steepness and steepness, or by providing a throttle downstream of the main flow path through which the gaseous solution flows, the static pressure inside this flow path is increased, and the gas-liquid reaction increases. It improves the dissolution efficiency. Pressurization of this part is adjusted by a throttle nozzle provided downstream of the main flow path. Furthermore, since it is difficult to accurately divide the surplus gas and the liquid at the branch point, it is set so that not only the gas but also a small amount of the liquid flows into the gas separation flow path, and when the liquid flows into this flow path, Since the liquid has a high density, the liquid will collect in the lower part, and this liquid level is detected by a sensor, and a solenoid valve attached to the end of the gas separation flow path to prevent the liquid from flowing out from the gas separation flow path Open and close. At this time, the gas flows upward from the gas separation channel, but the pressure is hardly reduced due to the restriction provided on the outflow side.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a gas-liquid pressurization reactor of the present invention. Figure 1
FIG. 3 shows a surplus gas separation type gas-liquid pressurized reactor 1 according to one embodiment of the present invention. A channel 12 that flows down is formed. An upwardly protruding gas separation flow path 16 is formed at a branch point 14 at the terminal end of the flow path 12 that flows down stepwise from above. The outlet 11 of the flow path 12 downstream of the branch point 14
Is connected to a main flow path 18 through which the gas-liquid mixed flow flows.
A throttle nozzle 20 is provided at a base end of the main flow path 18. Further, after the outlet 26 of the gas separation channel 16,
The throttle 28 and the solenoid valve 30 are connected, and capacitance type proximity sensors 22 and 24 are arranged on the side surface of the gas separation flow path 16. Gas release line 31 provided with this solenoid valve 30
When a harmful gas is used, a gas treatment device (not shown), for example, an ozone treatment device or the like is connected to the refrigeration unit, and performs processing of the released gas.

The operation of the gas-liquid pressurizing and mixing apparatus of this embodiment is as follows.
First, when a gas-liquid mixed flow 15 pressurized to a predetermined pressure flows into the flow channel 12 from the inflow port 10, a gas flow 32 and a liquid flow 34 are divided inside the flow channel 12. And the flow path 1
The inside of the flow path 12 is maintained in a pressurized state by the throttle nozzle 20 at the base end of the flow path 18 connected to the second outlet 11. Here, the relationship between the pressurization and the throttle nozzle 20 is as follows.
When the size of the inside of the flow path 12 is sufficiently large, it is given by the following equation from Bernoulli's theorem. P = ρu ^2/2 P: pressure in the flow path within 12 [rho: density of the liquid u: flow velocity in the throttle nozzle 20

In the flow branched at the branch point 14, the liquid and the gas also flow into the gas separation flow path 16 side, the liquid having a high specific gravity stays below, and the gas flows toward the upper side of the gas separation flow path 16. . In the gas separation flow path 16, the throttle nozzle 2 is set so that the liquid level is substantially located between the sensors 22 and 24.
0 and the inner diameter of the diaphragm 28 are adjusted. Then, when the liquid level rises to the position of the sensor 24 in response to the fluctuation of the liquid level, as shown in FIG. 2, the sensors 22 and 24 are also turned on, and the electromagnetic valve 30 is closed. As a result, the release of gas is stopped, the gas is filled in the upper part of the gas separation flow path 16, and the liquid level falls. When the liquid level falls below the sensor 22, both the sensors 22 and 24 are turned off,
The solenoid valve 30 is opened, and the liquid level starts to rise again in the gas separation channel 16. In this way, the surplus gas is released to the outside from the gas separation channel 16, and only the gas solution is supplied to the channel 1
Flow into 8.

[0010] In the gas-liquid pressurized reactor of the excess gas separation type of this embodiment, a large contact area can be obtained between the pressurized gas and the liquid, so that the gas-liquid reaction and the gas The conditions are such that the dissolution is performed very well. In addition, since the outlet 11 is provided at a position lower than the inlet 10 inside the flow channel 12, the liquid flow 34 of the gas-liquid mixed flow is more likely to flow downward, and the gas flow 32 is Road 1
2, so that even if the proportion of gas in the gas-liquid mixed flow flowing into the excess gas separation type gas-liquid pressurized reactor is small, the proportion of gas inside the apparatus increases. . As a result, even with a small amount of gas, efficient gas-liquid reaction and gas dissolution into liquid can be performed. Then, the surplus gas is separated in the gas separation channel 16 in the pressurized state, and the liquid in which the gas is dissolved is sent to the channel 18 in the pressurized state.

According to the surplus gas separation type gas-liquid pressurized reactor of this embodiment, the water generated by the gas-liquid reaction can be sprayed and pumped without a pump for spraying and pumping.

Here, in the surplus gas separation type gas-liquid pressurized reactor of this embodiment, the gas and the liquid may be separately injected into the flow channel 12. In this case, at least the gas is pressurized to a predetermined pressure and injected. Further, the throttle nozzle 20 may be mounted immediately after the surplus gas separation type gas-liquid pressurized reactor or downstream of the outlet 11. Further, the throttle nozzle 20 may be one having a single hole as shown in FIG. 1 or one having a plurality of holes, and a pressure adjusting valve or the like may be attached in place of the throttle nozzle 20 to change the pressure. It may be something that has been done. In the setting of the flow path 12, the surface on which the flow path 12 is formed does not necessarily have to be horizontal and vertical, and may be inclined. Further, the pipe may be meandering. In addition, if the condition that the outlet 11 is lower than the inlet 10 is satisfied, a part of the flow path 12 may be raised. Also, the throttle nozzle 20 may be used instead of a throttle at a watering portion such as a water sprayer. Further, in FIG. 1, a throttle 28, a solenoid valve 30
However, the solenoid valve 30 and the throttle 28 may be arranged in this order. Further, a pressure adjusting valve or the like may be used instead of the throttle 28.

Next, the excess gas separation type gas-liquid pressurization of this embodiment
A gas-liquid mixer 42 is attached to the inlet 10 of the reactor 1
The result is shown in FIG. As shown in FIG. 3, the gas-liquid mixer 42 includes a throat section 46 as a throttle section inside the mixer 42.
Is formed with a venturi tubular flow path 45 provided at the center. This venturi tubular channel 45
Downstream of the throat portion, a cylindrical gas inflow portion 47 having an inner diameter slightly larger than the throat portion 46 is formed.
On the downstream side of the opening, there is a widened portion 48 that is smoothly tapered.
Are formed. And in this gas inflow part 47,
A gas inlet 50 for mixing gas into the channel 45 is formed. The gas inlet 50 is connected to an end of a gas inflow pipe (not shown) for guiding a predetermined gas.

In the excess gas separation type gas-liquid pressurized reactor of this embodiment, the liquid flowing into the mixer 42 from the inflow pipe 44 is accelerated by the throat 46 of the venturi-shaped flow path 45, and once stopped. The pressure decreases, the flow velocity slows down through the expanding portion 48, the static pressure increases again, and the gas dissolves in the liquid. Here, the gas inlet 50 is slightly downstream of the throat 46, and the static pressure in this portion is relatively negative, so that the gas flows into the flow passage 45. The gas-liquid mixed flow formed here is made to flow into the surplus gas separation type gas-liquid pressurized reactor 1 similar to the first embodiment. Thereby, a gas-liquid dissolution reaction can be obtained more efficiently, and a large amount of gas-dissolved solution can be produced.

The sensor of the present invention may detect only the upper limit of the liquid level, close the electromagnetic valve by detecting the upper limit of the liquid level, and then open the electromagnetic valve after a predetermined time. Detect only the lower limit of the liquid level,
The solenoid valve may be opened by detecting the lower limit of the liquid level, and then closed after a predetermined time. Further, an electromagnetic valve may be used, which also serves as a throttle and an electromagnetic valve provided on the tip end side of the gas separation flow path.

[0016]

According to the present invention, the gas-liquid pressurized reactor of the surplus gas separation type is highly efficient simply by pumping a gas and a liquid or a mixed flow thereof into the device, and furthermore, the gas-liquid reaction is continuously performed. Alternatively, gas-liquid dissolution can be performed. Then, it is possible to easily and reliably perform watering, pressure feeding, and the like of the liquid generated by the gas-liquid reaction without using a dedicated pump.
