Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas-liquid reaction apparatus for the purpose of chemical reaction or heat exchange by contact between gas and liquid, and more particularly to a gas-liquid reaction apparatus applied to an excited oxygen generator of iodine laser.

[0002]

2. Description of the Related Art In order to carry out gas-liquid reaction with high efficiency, it is important that the contact area between the two is large, that is, the surface area of the reaction liquid is large. In order to meet this requirement, a bubbler method in which a reaction gas is jetted into a reaction solution in the form of a bubble is conventionally used, or a disk with a large number of disks mounted in the vicinity of a rotating shaft is rotated in a state of partially infiltrating the reaction solution and the disk surface is rotated. A disk method in which a gas is caused to act on a thin film of a solution formed in the above, or a jet method in which a jet flow is ejected into the gas to cause a contact reaction has been developed.

The iodine laser to which the present invention is mainly applied utilizes near infrared rays having a wavelength of 1.315 μm generated when excited iodine atoms return to the ground state. For industrial use, a chemically excited oxygen-iodine laser capable of continuous laser oscillation for exciting an iodine atom by utilizing a resonant energy transfer reaction between an excited oxygen molecule O ₂ (*) and an iodine atom is often used. Excited oxygen can be obtained by an ozone generator, but in general, basic hydrogen peroxide solution (BHP: Basic Hydrogen Peroxide), which is a mixture of hydrogen peroxide solution and potassium hydroxide or sodium hydroxide solution, and chlorine gas are used as raw materials. And a chemical reaction method of generating excited oxygen according to the following reaction formula (1).

H ₂ O ₂ + Cl ₂ + 2KOH = O ₂ (*) + 2KCl + 2H ₂ O (1)

As described above, also in the iodine laser generator, a gas-liquid reaction device is required to cause a gas-liquid contact reaction under a low pressure to generate excited oxygen.

With an iodine laser, the higher the excited oxygen partial pressure, the higher the performance of laser light emission. Therefore, the important point in the excited oxygen generator is how to generate excited oxygen at a high pressure with high efficiency. Incidentally, the bubbler method can generate excited oxygen of about 1 Torr with an efficiency of 60%, and the disk method can obtain excited oxygen of about 10 Torr.

Further, the jet method is more efficient. FIG. 5 is an explanatory diagram showing the structure of a known jet-type excited oxygen generator used in an iodine laser generator.

A basic hydrogen peroxide solution (BHP) obtained by mixing a potassium hydroxide solution or a sodium hydroxide solution with a hydrogen peroxide solution is pressurized by a transport pump (not shown) and reacted from the liquid intake port 101. It is supplied to the upper storage tank 103 above the container 100. 1.5 at the bottom of the upper storage tank 103
A nozzle plate 105 in which a large number of nozzles having a diameter of 0.5 mm are opened at an interval of 2 mm from 2 mm is provided, and a large number of columnar basic hydrogen peroxide solutions are ejected from the nozzles toward a lower storage tank 107 below. The liquid stored in the lower storage tank 107 is a mixed liquid of saline solution generated by the reaction and unreacted basic hydrogen peroxide solution. The saline solution is discharged from the solution outlet 109 to remove the saline solution, and the reaction container is again used. It is supplied into the reaction container 100 from the liquid intake port 101.

Chlorine gas mixed with a buffer gas such as argon or nitrogen is also supplied to the reaction vessel 100 from a gas intake port 111. Chlorine gas is the reaction vessel 100
In contact with the surface of the basic hydrogen peroxide solution hanging down in a cylindrical shape countercurrently, excited oxygen is generated. The excited oxygen gas generated by the gas-liquid contact reaction is sucked and discharged from the outlet 113 by a vacuum device (not shown) together with the gas of the reaction residue, and is supplied to the laser generator. With this device, a basic hydrogen peroxide solution was jetted into chlorine gas to successfully obtain excited oxygen with an excitation efficiency of 60% and a partial pressure of 30 Torr.

The following formula (2) is known as an empirical formula for achieving an excitation efficiency of 60%. Where P is pressure (Torr), S is gas-liquid contact area (cm ² ),
V is the reaction container volume (cm ³ ), σ = S / V (cm ⁻¹ ).
It is.

P = 10σ ^1/2 (2)

According to this empirical formula, it is understood that the efficiency is higher as the ratio of the surface area of the liquid to the volume of the reaction vessel is larger. Since the basic hydrogen peroxide solution formed in the reaction vessel of the jet-type excited oxygen generator has a cylindrical shape, there is room for increasing the surface area per volume by granulating the basic hydrogen peroxide solution. Further, since the gas and the liquid come into contact with each other to form fine liquid droplets on the surface of the cylindrical liquid column that flows down in the form of a jet, which are entrained in the gas, the gas velocity cannot be increased. If the reaction liquid is in the form of granular droplets, the gas-liquid contact area becomes large, and it is possible to suppress the generation of fine particles that accompany the gas from the rounded droplet surface surface tension. it can.

Based on this point of view, a product developed to supply a reaction liquid as a droplet is TEYER (WJThay
er III) etc., cross-flow type isometric droplet oxygen generator (Transv
erse-flow Uniform Droplet Oxygen Generator) (Article number AIAA 94-2454, 25th AIAA Plasmadynamics
and Lasers Conference, June 20-23, 1994). FIG. 6 is a structural conceptual diagram of a cross flow type equal-diameter droplet oxygen generator such as Sayer.

In the excited oxygen generator 200 such as Thayer, the basic hydrogen peroxide solution is dropped from the liquid reservoir 203 in the upper part of the reactor through the droplet jetting plate 205 provided with a large number of nozzles, while the straightening plate 212 is provided. The rectified chlorine gas is flowed so as to intersect the flow of the falling solution. Particularly, by horizontally reciprocally driving the droplet jetting plate 205, the dropping liquid stream is made into droplets of uniform size. It is characterized by this.

The droplet ejecting plate 205 is the piezoelectric actuator 2.
It is driven at about 4 kHz by 06. Then, depending on the speed of the solution jet, the diameter is about 0.4 mm to 0.5 m.
m droplets are continuously generated, and if the flow rate and temperature of the solution are set under appropriate conditions, the gas pressure is about 55% at 55 Torr.
Excited oxygen can be generated with the efficiency of.

[0016]

However, an excited oxygen generator such as Thayer produces droplets at fine intervals by horizontally driving a jet stream jetted from a nozzle of a droplet jet plate at a high frequency. A mechanism for driving the droplet ejection plate relative to the reactor container is required. For this reason, a complicated driving mechanism such as a device for supporting the droplet ejection plate on the reaction container or a driving device such as a piezoelectric actuator provided at a lateral position of the droplet ejection plate is used. In addition, since the droplet ejection plate that defines the boundary between the liquid reservoir and the reaction section in the upper part of the reactor has a movable portion, it is necessary to seal the liquid reservoir and the reaction section.

It is an object of the present invention to provide a new mechanism for converting a liquid stream into droplets in a gas-liquid reactor, and in particular, basic hydrogen peroxide applied to an excited oxygen generator of an iodine laser. It is an object of the present invention to provide a simple gas-liquid reaction device capable of increasing the surface area of a solution and improving the reaction efficiency.

In order to solve the above problems, a gas-liquid reaction device of the present invention has a liquid supply nozzle having a liquid jet nozzle, a piston mechanism, a gas-liquid reactor, and a gas supply unit. The high-frequency reciprocating motion of the piston mechanism changes the volume of the feed liquid holding part and ejects the feed liquid from the liquid injection nozzle into the gas-liquid reactor to form granules, and the granular feed liquid and gas in the gas-liquid reactor. It is characterized in that the supply gas supplied from the supply unit is brought into gas-liquid contact. Further, the gas-liquid reaction device of the present invention may be one that produces excited oxygen by using chlorine gas or a chlorine mixed gas as a supply gas and an aqueous alkaline hydrogen peroxide solution as a supply liquid.

Further, in the gas-liquid reaction device of the present invention, the driving frequency of the piston mechanism is preferably within the range of 1 kHz to 20 kHz.

Furthermore, it is preferable that the diameter of the liquid ejection nozzle is 0.1 mm to 1.0 mm. The iodine laser generator of the present invention is characterized in that the above gas-liquid reaction device is connected so that excited oxygen can be supplied to the iodine laser oscillator.

In order to solve the above-mentioned problems, the gas-liquid reaction method of the present invention changes the volume of the feed liquid holding portion holding the feed liquid at a high frequency so that a liquid jet nozzle provided in the feed liquid holding portion is provided. It is characterized in that a continuous liquid droplet is formed by jetting it into the gas through the liquid, and the liquid supply liquid and the liquid supply gas are brought into gas-liquid contact to perform a chemical reaction or heat exchange. In the gas-liquid reaction method of the present invention, the ejection speed of the supply liquid may be adjusted by the pressure when the supply liquid is pressed into the supply liquid holding portion. Furthermore, the gas-liquid reaction method of the present invention,
Excited oxygen may be produced by using chlorine gas or chlorine mixed gas as the supply gas and alkaline hydrogen peroxide solution as the supply liquid.

In the gas-liquid reaction device of the present invention, the volume of the supply liquid holding part is changed by the high frequency reciprocating movement of the piston mechanism attached to the supply liquid holding part to change the volume of the supply liquid from the liquid injection nozzle into the gas-liquid reactor. It is to be ejected into a granular form. Therefore, instead of a mechanism for moving the jet plate having the liquid jet nozzle to the left and right, a means for changing the volume of the supply liquid holding portion may be attached, and such means can be freely selected regardless of the position and shape of the jet plate. can do.

Further, since the liquid is an incompressible fluid, if the volume changes in a part of the supply liquid holding portion in the liquid tight state, the influence immediately reaches the liquid at the injection plate position, and the injection state changes. To do. In order to change the volume of the supply liquid holding unit, various methods such as a method of reciprocating the ceiling plate and a method of operating another volume movable member connected to the holding unit by piping can be applied. Further, the liquid ejection nozzle does not need a sealing mechanism which is statically fixed to the supply holding part and which is complicated and requires maintenance.

In an excited oxygen generator such as Sayer,
It is characterized by horizontally reciprocating the droplet ejection plate to rapidly shake the falling liquid flow in the horizontal direction to form droplets of uniform size. On the other hand, in the apparatus of the present invention, the pressure of the liquid ejected from the liquid ejection nozzle in the axial direction of the nozzle is changed to change the ejection speed of the liquid to form liquid droplets. Tends to become.

BEST MODE FOR CARRYING OUT THE INVENTION A gas-liquid reaction device according to the present invention will be described in detail below with reference to the drawings showing one embodiment. FIG.
[FIG. 3] is a structural conceptual diagram explaining one embodiment of the gas-liquid reaction device of the present invention. In the following, a case where the gas-liquid reaction device of the present invention is applied to an excited oxygen generator attached to an iodine laser device will be described.

In FIG. 1, the gas-liquid reaction device 1 comprises a gas-liquid contact portion 3, a liquid holding portion 5 provided on the upper portion and a liquid reservoir portion 7 provided on the lower portion. The liquid holding portion 5 is a space surrounded by a wall 9 in which a reaction liquid is hermetically held, and a liquid supply port 11 and
An injection plate 15 in which a large number of nozzles 13 having a diameter of 0.5 mm and a length of 5 mm are provided at intervals of 1.5 mm to 2.0 mm;
7 and an elastic joint 19 for connecting the space between the wall 9 and the ceiling plate 17 so as not to leak liquid. The ceiling plate 17 is connected to the fixing member 23 via an actuator 21 that has an electrostrictive element and is electrically driven.

A basic hydrogen peroxide solution, which is a mixture of a hydrogen peroxide solution and a potassium hydroxide solution, is conveyed from an external storage tank by a pump and is pressed into the liquid holding section 5 through the supply port 11. Since the liquid holding section 5 is already filled with the liquid,
The press-fitted aqueous solution is ejected in a columnar shape into the space of the gas-liquid contact portion 3 through the thin nozzle 13 according to the pressure.

When the actuator 21 for driving the ceiling plate 17 is driven by applying an alternating voltage of 1 kHz to 20 kHz, for example, 4 kHz, the ceiling plate 17 vibrates at the same frequency and changes the volume of the liquid holding portion 5. The volume or pressure of the basic hydrogen peroxide solution inside the liquid holding part 5 changes. For this reason, the flow velocity of the liquid passing through the nozzle 13 changes, so that the liquid ejected from the nozzle 13 cannot maintain a smooth columnar shape and has a shape in which bumpy unevenness is continuous. The humps separate from each other as they fall, and each becomes a small spherical droplet due to the surface tension.
If the diameter and length of the nozzle 13, the viscosity of the liquid, and the frequency and amplitude of changes in the liquid pressure are appropriately selected, the liquid droplets 16 will be granular when they are ejected from the nozzle 13.

A gas introducing pipe 25 for introducing gas is inserted in the lower side wall of the gas-liquid contact portion 3. The gas introducing pipe 25 has several holes 27 for ejecting gas into the gas-liquid contact portion 3. A gas discharge port 29 having a large diameter is provided on the upper side wall of the gas-liquid contact portion 3 and is connected to a vacuum device (not shown) through a laser resonator (not shown).

A gas flow 2 consisting of chlorine gas ejected from the gas introduction pipe 25 into the gas-liquid contact portion 3 or chlorine gas diluted with an inert gas such as argon, nitrogen or helium 2
8 is sucked into the vacuum device through the gas outlet 29 and is brought into gas-liquid contact while rising countercurrently between the basic hydrogen peroxide solutions 16 dropping from the liquid holding part 5 to the reaction formula (1 ) To generate excited oxygen molecules.

At this time, since the droplets 16 are extremely fine with a diameter of about 0.5 mm, the surface area of the reaction liquid is large and a highly efficient gas-liquid contact reaction is carried out. Also,
Since the droplet 16 is a sphere having a small diameter, the generation of fine mist on the gas-liquid contact surface is small due to the influence of the surface tension, and the gas 2
A mechanism for removing the mist associated with No. 8 is unnecessary and the waste of excited oxygen is prevented.

The excited oxygen molecules generated in the gas-liquid contact portion 3 are mixed with the iodine molecule or the iodine atom flow as soon as they are discharged from the gas discharge port 29 together with the diluting gas and the unreacted chlorine gas to dissociate the iodine molecules. Causes an energy transfer reaction with an iodine atom. The iodine atom that has undergone energy transfer is excited, falls to the ground state in the iodine laser resonator portion, and emits laser light having a wavelength of 1.315 μm.

The liquid reservoir 7 below the gas-liquid contacting unit 3 stores the post-reaction basic hydrogen peroxide solution, which is dripping, and the liquid discharge port 31.
The liquid is sent to a liquid recovery process (not shown) via. Since the basic hydrogen peroxide solution becomes a potassium chloride solution by the chemical reaction of the above formula (1), it is separated in the liquid recovery step and the unreacted components are again fed under pressure to the liquid holding part 5 above the gas-liquid contact part 3.

In the above embodiment, the liquid holding portion 5 is provided above the gas-liquid contact portion 3 to eject the solution vertically downward, but the droplet ejected through the nozzle 13 provided on the ejection plate 15 Since the velocity is sufficiently high from several m / s to 20 m / s, even if the liquid is jetted in the horizontal direction or the vertical upward direction, it reaches the end portion on the opposite side of the gas-liquid contact portion 3. Therefore, instead of the arrangement of the above-mentioned embodiment, the gas-liquid contact portion 3 is provided laterally, the jet plate 15 provided with a large number of nozzles is arranged at one end of the gas-liquid contact portion 3, and the receiving plate for the droplets is almost formed at the other end. It is also possible to provide a liquid reservoir part which is vertically installed and configured so that the liquid stopped on the receiving plate flows down to the reservoir part and accumulates, so that the liquid droplets are almost horizontally ejected to carry out the gas-liquid contact reaction. Further, in the description of the embodiment, the liquid and the gas are contacted in a countercurrent state, but they may be in parallel gas-liquid contact, or a cross flow type similar to an excited oxygen generator such as Thayer. It goes without saying that it may be configured to make contact.

In the above embodiment, the diameter of the nozzle 13 provided on the jet plate 15 is 0.5 mm. However, if the diameter is in the range of 0.1 mm to 1.0 mm, the basic hydrogen peroxide solution is jetted as droplets. You can Also, the nozzle length is 5m
Although m is set, the optimum value varies depending on the conditions. The nozzle 13 may have different cross sections on the outer surface and the inner surface of the spray plate. FIG. 2 is a drawing showing a cross section of a modified example of the nozzle 13 provided on the ejection plate 15. For example, when the plate thickness of the ejection plate 15 exceeds the required length of the nozzle 13, the nozzle 13 is countersunk as shown in FIGS. Is set to a required value, it is not necessary to make a hole having a length longer than necessary, drilling work is facilitated, and even if the conditions change and the dimension of the nozzle needs to be changed, the injection plate 15 Since it is not necessary to change the thickness of itself, it is economical because only the injection plate 15 portion can be replaced without changing the structure of the grip portion.

Further, it is preferable to provide a nozzle end shape with good drainage so that the liquid does not seep out onto the surface of the plate when the liquid is jetted from the nozzle and becomes a droplet immediately. FIG. 2D shows a pipe 1 with a sharp tip on the nozzle 13.
By embedding No. 4, the periphery of the nozzle hole was made into an acute angle so that the liquid was drained well. 2 (e), on the contrary, the tip of the nozzle 13 is widened and the liquid is retained at the tip until it becomes a weight that makes it easy to drop, and the nozzle is shaken off at once.

In addition, the actuator 21 of the above embodiment is composed of an electrostrictive element and is electrically driven.
As long as it can be driven in the range of kHz to 20 kHz, it may be one using a piezoelectric element or electromagnetically driven using a magnetostrictive element.

3 and 4 are sectional views showing another example of the structure for changing the volume of the liquid holding portion 5. In the above-described embodiment, the ceiling plate 17 is attached to the liquid holding portion 5 via the elastic joints 19 as a structure for changing the volume of the liquid holding portion 5 at a high frequency, but as shown in FIG. Alternatively, the diaphragm 33 may be provided in a part of the wall 9 so that the diaphragm 33 is driven at high speed by the piezoelectric element 35 or the like. Further, as shown in FIG. 4, a box 39 having a surface 37 formed of a piezoelectric element is provided on the inner wall 9 of the liquid holding part 5 and the volume of the liquid holding part 5 can be changed by driving the box 39. it can.

A known ultrasonic oscillator may be installed in the liquid holding section 5 and driven by a voltage of ultrasonic frequency. Even when configured in this manner, a pressure change based on a minute volume change due to the vibration of the ultrasonic oscillator is transmitted through the liquid to reach the solution in the nozzle portion, and the ejection speed from the nozzle is changed to generate a droplet. . Further, it may have a structure in which a chamber that changes in volume electrically or electromagnetically is connected to the liquid holding portion 5 by a pipe. Since the chamber and the liquid holding portion 5 are communicated with each other by an incompressible fluid, the volume change in the chamber has the same effect as the volume change of the liquid holding portion 5 itself. Such a structure has an advantage that the entire structure is extremely simple and robust by providing all the mechanical mechanisms on the chamber side without placing a movable part in the liquid holding part 5.

As described above, the gas-liquid reaction apparatus of the present invention can be used for general gas-liquid reaction to obtain efficient gas-liquid contact, and at the same time, to generate excited oxygen for exciting iodine atoms in an iodine laser. When used in the production step, high-pressure excited oxygen molecules can be obtained with high efficiency, and a high-performance iodine laser can be generated.
