Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas transfer method for delivering a transfer target gas to a target position by blowing out the transfer target gas into a space from a blowout port to the target position, and a gas transfer method therefor. The present invention relates to a gas transfer device used for.

[0002]

2. Description of the Related Art Conventionally, in the gas transfer by blowing, as shown in FIG. 13, the transferred gas G blown from the outlet 2 has a central streamline drawn substantially linearly toward a target point M. A transport mode of advancing in the space (may be curved to some extent due to a temperature factor or the like) (that is, gas transport by a simple jet flow), or as shown in FIG. Is moved so as to move toward the target point M in the space while being swirled so that its central streamline becomes a spiral shape (for example, Jitsuko Sho 51
(See Japanese Patent Publication No. -48546 and Japanese Utility Model Publication No. 52-27272).

[0003]

However, the above-mentioned FIG.
In the gas transport by the simple jet as shown in FIG. 13, the jet has a strong tendency to attract and mix the ambient gas in the blowing space O, and even if the gas is transported by the swirl flow as shown in FIG. 14, the simple jet in FIG. Is a jet flow that draws a central streamline that extends uniformly, only by the difference in whether the central streamline is a straight line or a spiral line. Because of the strong tendency to
In any of these conventional transportation modes, there is a problem that it is difficult to accurately reach the target location M of the transported gas G while maintaining the characteristics and properties of the transported gas G at the time of blowing.

As an example of gas transfer by blowing, when the above-mentioned conventional transfer mode is adopted in spot air conditioning in which temperature-controlled air is blown toward a location to be air-conditioned, the blown temperature is caused by the above-mentioned induced mixing and diffusion thereof. The temperature of the conditioned air is averaged with the ambient temperature, resulting in so-called mixed heat loss, which causes a reduction in heating and cooling effects and waste of energy, and as another example, delivers a special gas to a predetermined location. In particular, when the above-mentioned conventional transport mode is adopted, the concentration of the special gas received at a predetermined location due to the above-mentioned induced mixing / diffusion decreases, or it adversely affects the surroundings, or the special gas escapes. There is a problem that the loss is large and the yield is poor.

By the way, in carrying the predetermined amount of the gas to be carried G in the conventional carrying modes shown in FIGS. 13 and 14, if the blowout port 2 is made large in diameter to reduce the blowing air velocity, the above-mentioned attraction is obtained. Mixing and diffusion due to it are suppressed, but if the blowing air velocity is reduced, even a slight crosswind in the blowing space will change the direction of travel and disturb the blowing airflow itself. In this sense, it is difficult to accurately bring the transported gas G to the target location M.

A first object of the present invention is to allow the conveyed gas blown from the blow-out port to accurately reach the target location while maintaining its characteristics and properties well.

A second object of the present invention is to improve the air-conditioning effect in air-conditioning by using gas transfer by blowing.
In addition, it is to reduce energy consumption.

A third object of the present invention is to provide a gas transfer device suitable for achieving the above first or second object.

[Action]

[Operation of First Characteristic Configuration] As a result of various experiments on the air flow, the annular forming gas is swirled around the center of the cross section in the form of a cross section that is annular and orthogonal to the circumferential direction of the ring. With respect to the “vortex ring” (generally known as the swirl ring of cigarette smoke), even if the traveling speed in space is increased, the annular contour is clearly maintained for a long time, which tends to occur as shown in FIG. It was confirmed that compared with the simple jet flow as shown in Fig. 14 and the swirling flow as shown in Fig. 14, the induced mixing of the ambient gas and the diffusion due to it were less, in other words, the shape retention was high.

Since the shape retaining property is high as described above, it is less likely to be disturbed by the crosswind in the blowing space, and the advancing speed can be increased without the problems of attracting mixing and diffusion. It was confirmed that the straightness can be enhanced by giving a large traveling speed, and the deflection of the traveling direction due to the influence of cross wind can be reduced.

That is, in the first characteristic configuration of the present invention, the transported gas blown out from the air outlet is advanced in the space toward the target location in the state of the "vortex ring" as described above, thereby The carried gas is allowed to reach the target location in a state where the induced mixing and the diffusion due to the induced mixing are small, and the influence of the turbulence and the change of the traveling direction is less affected by the cross wind.

[Operation of Second Characteristic Configuration] In the second characteristic configuration of the present invention, the gas to be transported is temperature-controlled air, and the target location is an air-conditioned location, and the gas transport method according to the first characteristic construction described above. By performing the above, the temperature-controlled air blown out from the air outlet advances in the space in the state of the vortex ring to reach the air-conditioned location, and the air-conditioned location is air-conditioned.

In other words, the temperature-controlled air blown out is advanced in the space in the state of the vortex ring so as to induce the induced mixing,
Further, the temperature-controlled air is allowed to reach the air-conditioned location in a state in which the temperature-controlled air is diffused in a small amount and is less affected by a turbulence in the blowing space and a change in the traveling direction.

[Operation of Third Characteristic Configuration] On the other hand, regarding the formation of the vortex ring as described above (see FIG. 3), as a result of various experiments, the chamber pressure of the air chamber 3 in which the air outlet 2 is formed is pulsed. When the pressure G is changed to the positive pressure side, the gas G in the air chamber is suddenly and vigorously discharged from the air outlet 2, and the discharged gas G has the above-described vortex ring R, that is, the annular shape and the annular circumference. As a cross section orthogonal to the direction, the vortex ring R in which the annular forming gas rotates in a vortex around the center of the cross section (specifically, in the direction from the inner ring to the outer ring around the discharge tip).
Was confirmed to be formed.

This is because when the chamber pressure of the air chamber 3 is changed to the positive pressure side in a pulsed manner, the gas G in the air chamber is expelled from the outlet 2 at that moment, but the positive pressure side of the chamber pressure is reached. Is a pulse-like change, and the discharge of the internal gas is interrupted in an extremely short time.Also, it is speculated that the outlet inertia tends to be negative pressure immediately after the discharge due to the inertia of the discharge. Then, it is considered that the discharge gas G forms the above-mentioned vortex ring R after the discharge.

The vortex ring R formed in this way is
It was also confirmed that the particles travel in the space with the momentum in the discharging direction given during discharging.

That is, the third characteristic structure of the present invention is to form the vortex ring of the transported gas by utilizing the above phenomenon, the transported gas is supplied to the air chamber by the supply means, and By changing the chamber pressure of the chamber in a pulsed manner to the positive pressure side by the operating means, the carrier gas in the air chamber is discharged into the space as the above-mentioned vortex ring from the outlet, and is discharged in the state of the vortex ring. Is moved toward the target location in the space.

[Operation of Fourth Characteristic Configuration] In the fourth characteristic configuration of the present invention, the vortex ring made of the gas to be conveyed is blown by causing the pulse-like change of the chamber pressure to be repeated at predetermined time intervals. It is repeatedly sent from the outlet into the space.

[Operation of Fifth Characteristic Configuration] In the fifth characteristic configuration of the present invention, immediately after the pulse-like change of the chamber pressure to the positive pressure side, the chamber pressure is changed to the negative pressure side in a pulsed manner. The negative pressure tendency of the blowout port immediately after the discharge of the transported gas is promoted, and thus the strength of the vortex (the vortex-like rotation around the center of the cross section) is increased in the formation of the vortex ring after the discharge from the blowout port. Make it higher

[Operation of Sixth Characteristic Configuration] In the sixth characteristic configuration of the present invention, by instantaneously reducing the volume of the air chamber, the chamber pressure is pulsedly changed to the positive pressure side, and The carrier gas is discharged from the outlet as the vortex ring.

It should be noted that the fourth feature described above is provided by the sixth characteristic configuration.
In the case of implementing the characteristic configuration, by instantaneously reducing the volume of the air chamber and then expanding and restoring the volume of the air chamber, the pulse pressure change of the chamber pressure to the positive pressure side is repeated. That is, the discharge of the vortex ring can be repeated.

When the fifth characteristic structure is implemented in the sixth characteristic structure, the volume of the air chamber is instantaneously expanded immediately after the volume of the air chamber is instantaneously reduced. Thus, immediately after the pulse-like change of the chamber pressure to the positive pressure side, that is, immediately after the discharge of the transported gas, the chamber pressure can be changed to the negative pressure side in a pulse-like manner.

[Operation of Seventh Characteristic Configuration] In the seventh characteristic configuration of the present invention, the elastically displaceable chamber wall forming body is hit to elastically displace the chamber wall forming body toward the room. As a result, the volume of the air chamber is instantaneously reduced, and thereby the chamber pressure of the air chamber is changed to the positive pressure side in a pulsed manner.

It should be noted that, by the seventh characteristic construction, the fourth
In the case of implementing the characteristic configuration, it is possible to repeat the pulse-like change of the room pressure to the positive pressure side by repeating the impact at a predetermined time interval.

Further, in the case of implementing the fifth characteristic configuration in the seventh characteristic configuration, the chamber wall forming element is momentarily elastically displaced toward the indoor side by striking, and then the chamber wall forming element is moved. By performing free return displacement to the outside of the chamber by elasticity, the chamber pressure can be pulsed to the negative pressure side immediately after the pulsed change of the chamber pressure to the positive pressure side.

[Operation of Eighth Characteristic Configuration] In the gas carrying device according to the eighth characteristic structure of the present invention, a shock wave is radiated to the elastically displaceable chamber wall forming body, and an impact force is applied to the chamber wall forming body. By applying this, the chamber wall forming body is momentarily elastically displaced to the indoor side, thereby instantaneously reducing the volume of the air chamber and changing the chamber pressure of the air chamber to the positive pressure side in a pulsed manner. .

It should be noted that, by the eighth characteristic construction, the fourth
In the case of implementing the characteristic configuration, it is possible to repeat the pulse-like change of the chamber pressure to the positive pressure side by repeating the shock wave radiation at a predetermined time interval.

Further, in the case of implementing the fifth characteristic configuration in the eighth characteristic configuration, the chamber wall forming element is momentarily elastically displaced toward the indoor side by shock wave radiation, and then the chamber wall forming element is displaced. By freely displacing to the outside of the room by elasticity, immediately after the pulse-like change of the room pressure to the positive pressure side,
The chamber pressure can be changed in a pulsed manner to the negative pressure side.

[Operation of Ninth Characteristic Configuration] In the ninth characteristic configuration of the present invention, the pressurized supply of the transported gas to the air chamber is suddenly started or the pressurized supply amount thereof is rapidly increased. Thus, the supply pressure of the gas to be transported to the air chamber causes the chamber pressure of the air chamber to be changed to the positive pressure in a pulsed manner, whereby the gas to be transported in the air chamber is discharged from the outlet as the vortex ring.

It should be noted that, by the ninth characteristic construction, the fourth
In the case of implementing the characteristic configuration, the rapid start and stop of the pressurized supply are repeated, or the abrupt increase and decrease of the pressurized supply are repeated, so that the pulse pressure change of the room pressure to the positive pressure side, that is, The discharge of the vortex ring can be repeated.

[Operation of Tenth Characteristic Configuration] The tenth aspect of the present invention
In the characteristic configuration, the oscillation circuit using the fluid element is caused to self-oscillate by using the carrier gas to be supplied to the air chamber as the working fluid, and the gas that intermittently repeatedly pressurizes and supplies the gas to the air chamber by this self-excited oscillation. Control the supply.

Every time the pressurization supply is started in this repeated interruption, the pressurization supply is started so that the chamber pressure of the air chamber is pulsed to the positive pressure side as the carrier gas is supplied to the air chamber. This is changed, and thereby, the transported gas in the air chamber is repeatedly discharged from the outlet as the vortex ring.

【The invention's effect】

[Effect of First Characteristic Configuration] In the gas transfer method according to the first characteristic configuration of the present invention, the induced mixing of the ambient gas in the blowing space and the resulting diffusion are small, and the crosswind in the blowing space is also reduced. Since it is less likely to be affected by turbulence and change in direction of travel, the characteristics and properties of the gas to be transported at the time of blowing are compared to the transport by the simple jet shown in FIG. 13 or the swirl flow shown in FIG. With the above condition being maintained well, the transported gas can reach the target location more accurately.

As an example, in the case where a special gas is delivered to a predetermined location by gas delivery by blowing, there is a problem that has occurred in the conventional delivery by a simple jet flow or a swirling flow, that is, because of the attractive mixing of ambient gas. , The concentration of the special gas received at a predetermined location becomes lower than the desired value, and because of the turbulence and diversion due to the diffusion due to the induced mixing and the influence of the cross wind, the special gas adversely affects the surroundings, or the special gas It is possible to effectively prevent that the yield loss is deteriorated due to a large amount of dissipation loss.

[Effects of Second Characteristic Configuration] In the gas conveying method according to the second characteristic configuration of the present invention, the heat loss of mixing in which the temperature of the blown temperature-controlled air is averaged with the ambient temperature by the induced mixing and the diffusion caused thereby. Can be effectively prevented, and the temperature-controlled air can be effectively prevented from being dissipated due to the influence of cross wind. Therefore, it is possible to secure a high cooling and heating effect and save energy consumption.

[Effects of Third Characteristic Configuration] In the gas carrier device according to the third characterizing structure of the present invention, the carrier gas can be reliably sent into the space in the state of the vortex ring. Alternatively, it is possible to accurately carry out the gas transporting method according to the two characteristic configurations and to reliably obtain the effects of these gas transporting methods.

[Effect of Fourth Characteristic Configuration] In the gas conveying device according to the fourth characteristic structure of the present invention, the vortex ring is made to sequentially reach the target position of the transfer at a predetermined time interval, and the target gas is transferred to the target gas position. Can be sent continuously.

It should be noted that how to determine the above-mentioned predetermined time interval is arbitrary, but by changing this time interval,
It is also possible to change the transport amount of the transported gas per unit time.

[Effect of Fifth Characteristic Configuration] In the gas transfer device according to the fifth characteristic configuration of the present invention, since the strength of the vortex flow can be increased in forming the vortex ring, the shape retention of the vortex ring can be enhanced. As a result, it is possible to further reduce the amount of the induced mixing and the diffusion thereof, and to further reduce the influence of the crosswind, thereby further improving the reachability of the vortex ring to the target location.

[Effect of Sixth Characteristic Configuration] In the gas transfer device according to the sixth characteristic configuration of the present invention, since the volume of the air chamber itself is changed to change the chamber pressure of the air chamber, the pressure generated in other parts is changed. Compared with the form in which the chamber pressure of the air chamber is changed by introducing it into the air chamber, the chamber pressure of the air chamber is pulsed with good response and accuracy without being affected by pressure propagation delay or pressure loss in the pressure guiding process. The vortex ring of a desired shape can be accurately and stably formed.

[Effect of Seventh Characteristic Configuration] In the gas transfer apparatus according to the seventh characteristic configuration of the present invention, since the simple method of striking the chamber wall forming body is used for changing the chamber pressure in a pulsed manner, The structure can be simplified.

[Effect of Eighth Characteristic Configuration] In the gas transfer device according to the eighth characteristic structure of the present invention, since the chamber wall forming body is elastically displaced without mechanical contact with the chamber wall forming body, When the formed body is momentarily elastically displaced to change the chamber pressure in a pulsed manner, high device durability can be obtained as a form in which device deterioration due to mechanical contact is avoided.

[Effect of Ninth Characteristic Configuration] In the gas transfer device according to the ninth characterizing structure of the present invention, the supply of the gas to be transferred to the air chamber is used to change the chamber pressure of the air chamber in a pulsed manner. The device configuration can be simplified as compared with the case where a dedicated means as a pressure source for changing the pressure is separately provided.

[Effect of Tenth Characteristic Configuration] The tenth aspect of the present invention
In the gas transfer device according to the characteristic configuration, as in the case of the ninth characteristic configuration, the supply of the gas to be transferred to the air chamber is used to change the chamber pressure of the air chamber in a pulsed manner. An oscillating circuit that uses the gas to be transported as the working fluid controls the pulse pressure of the chamber pressure repeatedly.Therefore, a dedicated means for providing a pressure source for changing the chamber pressure may be provided separately, or Simplify the device configuration compared to performing control that repeats pulse pressure changes using an electronic circuit or electric circuit such as a microcomputer or a fluid circuit that uses a dedicated fluid different from the carrier gas as the working fluid. You can

Similarly to the above, the control means C is configured to repeatedly change the chamber pressure of the air chamber 3 in a pulsed manner to the positive pressure side at predetermined time intervals and repeatedly discharge the vortex ring R from the outlet 2.

[Sixth Embodiment] FIG. 10 shows still another specific example of the gas transfer device for carrying out the gas transfer by the vortex ring. As the supply means S for supplying the transfer target gas G to the gas chamber 3, the transfer target S is supplied. A pressure feeding device 11 such as a fan or a compressor for supplying the gas G at a predetermined pressure to the air chamber 3 via the gas supply path 4 is provided.

A fluid element is used as the operation means T for changing the chamber pressure of the air chamber 3 to the positive pressure side in a pulsed manner and the control means C for repeatedly performing the pulsed change of the chamber pressure at a predetermined time interval. The oscillation circuit 12 is installed in the gas supply path 4.

The oscillation circuit 12 is composed of the pressure feeding device 11
The self-excited oscillation is performed by using the transported gas G that is pressurized and supplied as a working fluid, and the oscillation of the pressurized gas supply to the air chamber 3 is repeated at predetermined time intervals. With each start of the pressure supply, the start of the pressure supply changes the chamber pressure of the air chamber 3 in a pulsed manner to the positive pressure side in accordance with the supply of the transported gas G to the air chamber 3, whereby the transported gas is transferred. G is repeatedly discharged from the outlet 2 as the vortex ring R at predetermined time intervals.

The fluid element 13 constituting the oscillation circuit 12 is supplied with an alternative signal fluid to the first and second control ports cp1 and cp2, so that the main jet flow (that is, the additional jet flow) from the supply port ip is added. An adhesive type element is used for switching between a state in which a flow of the conveyed gas G pressurized and supplied from the pressure supply device 11 is guided to the first output port op1 and a state in which it is guided to the second output port op2, and As the circuit configuration of the oscillation circuit 12, the first output port op1 is connected to the air chamber 3 via the tank 14, and the tank 14 and the first control port cp are connected.
1 is connected by the first signal path r1, while the second output port cp2 and the second control port cp2 are connected by the second signal path r2.

That is, from the state in which the main jet flow from the supply port ip is introduced to the first output port cp1, the tank 1
When the internal pressure of the tank 14 rises to a predetermined pressure due to the gas supply to the air chamber 3 via 4, the signal fluid pressurized and supplied from the tank 14 to the first control port cp1 via the first signal path r1. Due to (the transported gas G in the tank 14), the supply port ip
The main jet flow from is switched to a state in which the main jet is guided to the second output port cp2, whereby the gas pressurized supply to the air chamber 3 is cut off.

When the main jet from the supply port ip comes to be guided to the second output port cp2, the second output port op2
The main jet flow from the supply port ip is restored to the first by the signal fluid (the transported gas G sent from the second output port op2) pressurized from the second control port cp2 to the second control port cp2. The state is switched to the state where it is guided to the output port cp1, and thereby, the gas pressure supply to the air chamber 3 is started, and the chamber pressure of the air chamber 3 changes to the positive pressure side in a pulsed manner by the start of the pressure supply. Then, thereafter, this gas supply is repeated intermittently as self-excited oscillation.

In the oscillation circuit 12, the discharge frequency interval of the vortex ring R can be changed by changing the oscillation frequency by changing the capacity of the tank 14.

Various fluid elements can be adopted, and various concrete circuit configurations of the oscillation circuit can be changed according to the fluid element to be used.

(2) Instead of repeatedly interrupting the gas pressure supply to the air chamber 3 by the oscillation circuit 12 using the fluid element,
As shown in FIG. 11, a valve device 15 is provided in the gas supply path 4 for pressurizing the transported gas G to the air chamber 3, and the valve device 15 is repeatedly opened and closed by a control device 16 using an electronic circuit. The gas pressure supply to the air chamber 3 may be repeatedly interrupted by operating, and the chamber pressure of the air chamber 3 may be repeatedly changed to the positive pressure side in a pulsed manner.

(3) Instead of intermittently interrupting the gas pressurization supply to the air chamber 3 by completely shutting it off, the amount of pressurization and supply of the conveyed gas G to the air chamber 3 is rapidly increased by operating the valve device 15 or the like. The increase and the decrease may be repeated, whereby the chamber pressure of the air chamber 3 may be repeatedly changed to the positive pressure side in a pulsed manner.

(4) When adopting a mode in which the volume of the air chamber 3 is sharply reduced to change the chamber pressure of the air chamber 3 in a pulsed manner to the positive pressure side, the piston 17 is internally provided as shown in FIG. The cylinder chamber of the cylinder 18 may be the air chamber 3, and the piston 17 may be abruptly slidably displaced to change the chamber pressure of the air chamber 3 in a pulsed manner.

(5) As the supply means S for supplying the transported gas G to the air chamber 3, the gas supply passage 4 is used as in the above-mentioned embodiments.
Instead of the form in which the transported gas G is sent to the air chamber 3 via
A mode in which the transported gas G is generated inside the air chamber 3 may be adopted.

(6) The shape of the air chamber 5 is not limited to a box shape such as a rectangular parallelepiped or a cube, but can be modified in various ways such as by forming it into a spherical shape. The shape is not limited to a cylindrical shape, and various configuration changes are possible, for example, a rectangular tube shape or a shape in which a circular or polygonal opening is formed in the chamber wall. .

(7) A method for carrying gas according to the present invention, and
The gas transfer device is applicable not only to air-conditioning applications but also to transfer various gases in various fields, for example, supplying scented air, gas mixed with fine powder, or gas mixed with mist to a predetermined target location. It can also be applied in cases.
