Description

  The present invention relates to an aroma mist spraying system for diffusing essential oils into a space for aroma.

In recent years, aromatherapy aimed at healing and relaxation has been spreading. Aromatherapy is a treatment that evaporates natural plant essential oils and leads the person in good physical and mental directions by the effects of their ingredients.
In the method of diffusing only essential oil in the space, it is difficult to control the concentration of essential oil components in the space and the concentration of essential oil components in a part of the space becomes high. Usually, the essential oil is heated with water and gradually evaporated. Alternatively, water mixed with essential oil is sprayed as an aroma mist using an ultrasonic humidifier or the like and diffused into the space (for example, see Patent Document 1).

JP 2000-229121 A

  By the way, in order to prevent workers' accidents and improve work efficiency in a large space such as a factory, it is conceivable to diffuse essential oil that can improve concentration, but it is sprayed with an ultrasonic humidifier. Since the amount that can be produced is small even in a large scale, there is a problem that it is difficult to uniformly diffuse the essential oil in a wide space in a short time.

  An object of the present invention is to provide an aroma mist spraying system that uniformly disperses essential oil in a short time in a wide space.

  The aroma mist spraying system according to the present invention is a fragrance mist spraying system for spraying water mixed with essential oil as a mist for aroma, the pump supplying the water under pressure, and a proximal end connected to the pump Connected to the branch end side of the main water distribution pipe, and a mixer for generating aroma water by mixing the water and the essential oil at a predetermined ratio, and connected to the mixer A line mixer that emulsifies the aroma water, a branch pipe that is connected to the line mixer at the base end side, and a branch pipe that is branched from the branch pipe and that is emulsified and sprayed as a mist. A plurality of mist nozzles and a control panel for controlling the whole are provided.

  The effect of the aroma mist spraying system according to the present invention is that the aroma mist particles sprayed by spraying pressurized aroma water in which pressurized water and essential oil are uniformly emulsified by a line mixer from a spray nozzle at high pressure. Since the diameter is 100 μm or less and fine particles, the aroma mist is instantly and uniformly diffused in a very wide space, and the essential oil component contained in the aroma mist is uniformly distributed over a wide space.

FIG. 2 is a cross-sectional view of the extension pipe according to Embodiment 1 of the present invention. FIG. 3 is a sectional view taken along the central axis of the spray nozzle according to Embodiment 1 of the present invention. FIG. 4 is a diagram illustrating a state in which mist is sprayed from the spray nozzle. FIG. 5 is a configuration diagram of the pressurized water supply apparatus according to Embodiment 1 of the present invention. FIG. 6 is a timing chart of aroma mist spraying.

  As shown in FIG. 1, the mist spray system 1 for fragrance according to Embodiment 1 of the present invention supplies water from a pressurized water supply device 5 and a pressurized water supply device 5 that supply pressurized aroma water in which water is pressurized and essential oil is mixed. As a branch pipe through which the pressurized aroma water flows, a plurality of extension pipes 12 branched from the middle of the sub-distribution pipe 4, and a mist nozzle provided at the outlet end of the extension pipe 12 A spray nozzle 10 is provided. Note that water is supplied from the water supply 7 to the pressurized water supply device 5.

The sub-distribution pipe 4 stands vertically from the ground, and is subsequently wound along, for example, a factory beam.
The extension piping 12 is extended from the sub-distribution pipe 4, and what is necessary is just to determine an appropriate number according to the magnitude | size of the plant | facility which sprays aroma mist.
And the installation altitude of the spray nozzle 10 is 4 m, for example. The installation height of the spray nozzle 10 is determined depending on the average particle size and the maximum particle size of the aroma mist.

  As shown in FIG. 2, the extension pipe 12 is a cylindrical pipe that bends downward in the longitudinal direction. At the other end, the central axis of the cylindrical pipe is at an angle θ22 from the horizontal plane including the lower side of the child water distribution pipe 4. Tilt to bow five degrees. The extension pipe 12 is made of stainless steel.

  As an example, the spray nozzle 10 has a substantially cylindrical housing 20 as shown in FIG. Then, along the central axis of the cylindrical housing 20, a two-stage cylindrical pressurized water receiving cavity 21 in which the upstream diameter receiving the pressurized aroma water supplied from the extension pipe 12 is larger than the downstream diameter, A pressure check valve 22 is housed, and a valve housing cavity 24 and a piece 25 which are larger in diameter than the downstream side of the pressurized water receiving cavity 21 and whose outer edge is partitioned by a rib 23 protruding in the central axis direction are housed. A jet generating cavity 28, which is located downstream of the ribs 23 and includes a cylindrical cavity 26 having the same diameter as the upstream side of the pressurized water receiving cavity 21 and a funnel-shaped cavity 27 connected to the cavity 26, and the tip of the funnel-shaped cavity 27 The orifice 29 is provided continuously.

A pressure-sensitive check valve 22 that opens and closes an opening 21 a on the downstream side of the pressurized water receiving cavity 21 is inserted into the valve housing cavity 24.
When the pressure-sensitive check valve 22 abuts on the opening 21 a on the downstream side of the pressurized water receiving cavity 21, a blocking ball 30 that blocks the flow of the pressurized aroma water and one end abuts the blocking ball 30 and contacts the blocking ball 30. The spring 31 is bent so that the spring pressure is applied and the other end is fixed to the rib 23. The spring constant of the spring 31 is set so that the predetermined spring pressure separates the blocking ball 30 and the opening 21a of the pressurized water receiving cavity 21 when the water pressure in the pressurized water receiving cavity 21 reaches 1 MPa. If the predetermined spring pressure is set low, it takes a long time to reach a high pressure when separated and water droplets having a large diameter are sprayed. Further, if the predetermined spring pressure is close to the spray water pressure, the blocking ball 30 cannot be sufficiently separated from the opening 21a, so that the amount of water is restricted. For this reason, the predetermined spring pressure is preferably 0.4 to 1.5 MPa.

  Further, in the jet generation cavity 28, the pressure water is ejected as a swirling jet, and the piece 25 for colliding with the inner surface of the funnel-shaped cavity 27 is in contact with the inner surface of the cylindrical cavity 26, and the direction of the central axis of the spray nozzle 10 Move while sliding. A spiral groove 32 is dug in the side surface of the piece 25, and a swirl flow path for swirling and ejecting pressurized water is formed by the groove 32 and the inner surface of the cylindrical cavity 26.

Next, a procedure for spraying pressurized aroma water in the spray nozzle 10 will be described.
When the pressurized aroma water is poured into the pressurized water receiving cavity 21 and the water pressure reaches a predetermined value, the blocking ball 30 is pushed and the pressurized aroma water flows into the valve housing cavity 24.
Then, the pressurized aroma water pushes one end face of the piece 25 from the hole 23a formed in the center of the rib 23, and the piece 25 is moved along the central axis of the spray nozzle 10 in the direction of the funnel-shaped cavity 27. The pressurized aroma water passes through the groove 32 on the 25 side surfaces while being swirled, and is jetted from the end of the groove 32.
This jet collides with the inner surface of the funnel-shaped cavity 27 to become a collision jet and is sprayed from the orifice 29 as an aroma mist.

Next, the sprayed aroma mist will be described. The aroma mist in this invention means the water droplet of the small diameter in which the essential oil was emulsified. The average particle diameter of the aroma mist is the body area average particle diameter (referred to as Sauter average diameter) measured by the laser diffraction method at a location 50 mm away from the tip of the orifice 29 on the central axis of the spray nozzle 10. In the laser diffraction method, measurement was performed in the same manner five times using a laser diffraction particle size measuring device (manufactured by Malvern Instruments, master size-S type, laser used: He-Ne laser). It is used as the diameter.
When the spray water pressure was 6 MPa from the spray nozzle 10 used in Embodiment 1, the Sauter average particle size was 20 μm. If the spray water pressure is low, the average particle size of the aroma mist increases, the spray flow rate decreases, and the spray amount of the essential oil component decreases. Also, if the spray water pressure is high, the average particle size of the aroma mist decreases and the spray flow rate increases, but if it is too high, a large shock wave is added to the piping and the like, which is not preferable for safety. For these reasons, the spray water pressure is preferably between 2 MPa and 10 MPa. The average particle size of the aroma mist is measured using a laser diffraction particle size measuring device, but may also be measured using a Doppler phase particle size measuring device or the like. At this time, since the average particle size differs depending on the type of measuring instrument, it is necessary to measure and compare the aroma mist sprayed under the same conditions. For example, the 90% volume particle size of the aroma mist sprayed when the spray water pressure is 6 MPa from the spray nozzle 10 was 60 μm, and the 10% volume particle size was 3 μm.

Next, the state of spraying of the aroma mist will be described and the spray region will be defined. As shown in FIG. 4, the aroma mist is sprayed in a cone having a center line on the central axis of the spray nozzle 10 in the vicinity of the orifice 29 and having the exit of the orifice 29 as a vertex. This conical region is referred to as a spray region 34 and the apex angle of the cone is referred to as an injection angle 35. The side surface of the spray region 34 is referred to as a spray outer edge 36.
The spray region 34 can adjust the cone injection angle 35 by adjusting the shape of the orifice 29. When the cone spray angle 35 is narrowed, the aroma mist flies far away. When the cone spray angle 35 is widened, the aroma mist drifts near the spray nozzle 10. Usually, it is preferable to set the injection angle 35 to about 45 degrees, but it is not limited to 45 degrees.
By adjusting the injection angle 35 in this way, the spray region 34 can be positioned below the horizontal plane that crosses the orifice 29.

  And the essential oil vaporized by evaporation of the aroma mist drifts, and since the descending airflow is generated by the evaporated water, the sprayed aroma mist descends with the downward airflow. And the aroma mist is completely evaporated during the descent, and the essential oil is completely vaporized.

As shown in FIG. 5, the pressurized water supply device 5 includes a high-pressure pump 40, a main valve 41 disposed on the downstream side of the high-pressure pump 40, a main water distribution pipe 42 having a base end connected to the downstream side of the main valve 41, A mixer 43 connected to the branch end side of the main water distribution pipe 42, an essential oil tank 44 as an essential oil source for supplying essential oil to the mixer 43, a line mixer 45 disposed on the outlet side of the mixer 43, and a line mixer 45 An intermediate water distribution pipe 46 that is connected to the outlet side of the water outlet and is branched into two at the branch end side, an output valve 47 that is connected to a branch end side of one branch of the intermediate water distribution pipe 46, and an intermediate water distribution pipe A drain valve 48 connected to the branch end side of the other branch of 46, a drain pipe 49 for draining water from the drain valve 48, and a mist control panel 50 for controlling the pressurized water supply device 5. .
The line mixer 45 is a float type mixer, and the fluid flowing into the line mixer 45 is mixed as it is. That is, water and essential oil are mixed in advance in the mixer 43, and no new object is added in the line mixer 45.

The main water pipe 42, the intermediate water pipe 46, the drain pipe 49, and the sub water pipe 4 are each made of stainless steel. Further, the high pressure pump 40 and the main valve 41 are communicated by a rubber blade hose 51 to smooth the pulsation generated by the positive displacement high pressure pump 40.
Further, in order to remove dust contained in the pressurized water, a 20 μm square opening filter (not shown) is interposed at the outlet of the high-pressure pump 40.
Further, in order to supply pressurized water with a small amount of metal ions so that scale does not deposit on the main water distribution pipe 42, the sub water distribution pipe 4, and the spray nozzle 10, softened water is supplied to the high-pressure pump 40 from a water softener (not shown). Has been.

  The mist control panel 50 has a spray sequence control means for controlling the high-pressure pump 40 and various valves, and a timer for measuring time. The mist control panel 50 is composed of a computer having a CPU, a RAM, a ROM, and an interface circuit.

Next, a sequence for supplying aroma water from the pressurized water supply device 5 will be described with reference to FIG.
The mist control panel 50 opens the drain valve 48 at the same time as opening the main valve 41 when the timer reaches a radiation setting time set in advance so as to radiate the aroma mist.
Next, the mist control panel 50 turns on the high pressure pump 40 and supplies pressurized water from the blade hose 51 to the main water distribution pipe 42. Then, the air remaining in the main water distribution pipe 42, the mixer 43, the line mixer 45, and the intermediate water distribution pipe 46 is pushed out together with water from the drain valve 48, and the main water distribution pipe 42, the mixer 43, and the line mixer 45 In the intermediate water distribution pipe 46, a uniform water pressure is applied.
Next, the mist control panel 50 closes the drain valve 48. Thereby, the water pressure in the main water distribution pipe 42, the mixer 43, the line mixer 45, and the intermediate water distribution pipe 46 reaches a desired water pressure, for example, 6 MPa.
Next, the mist control panel 50 opens the output valve 47 so that pressurized water is supplied to the spray nozzle 10 via the sub-distribution pipe 4. At this time, since the essential oil is mixed into the pressurized water from the essential oil tank 44 and emulsified by the line mixer 45, the aroma water emulsified is supplied to the spray nozzle 10.
At this time, the water pressure applied by being injected into the pressurized water receiving cavity 21 reaches approximately 0 MPa to 6 MPa in 4 seconds. When the water pressure becomes 1 MPa or higher in this way, the pressure-sensitive check valve 22 of the spray nozzle 10 is opened, and spraying of the aroma mist is started.

Conversely, when spraying the aroma mist is finished, the mist control panel 50 opens the drain valve 48 to reduce the water pressure in the main water distribution pipe 42, the mixer 43, the line mixer 45, and the intermediate water distribution pipe 46. Then, since the water pressure in the pressurized water receiving cavity 21 is reduced to 1 MPa or less, the pressure sensitive check valve 22 is closed, and the spray of the aroma mist is finished.
Then, about 3 seconds after the drain valve 48 is opened, the high-pressure pump 40 is turned off and the output valve 47 is closed. Thereafter, the main valve 41 and the drain valve 48 are closed.

Thus, after the water pressure in the main water distribution pipe 42 is once stabilized to a desired value, the water pressure of the pressurized water supplied to the spray nozzle 10 is changed from 0 MPa to 6 MPa in a few seconds by supplying water to the child water distribution pipe 4. Can change. And since the pressure sensitive check valve 22 is suddenly opened and the spraying time can be shortened when the water pressure is low, the aroma mist having a large particle size seen when spraying when the water pressure is low. It is hardly sprayed.
Further, when the drain valve 48 is opened, the water pressure in the main water distribution pipe 42 is suddenly lowered, the pressure sensitive check valve 22 is suddenly closed, and the spraying time in a low water pressure state can be shortened. A large amount of aroma mist seen when sprayed at a low water pressure is hardly sprayed.

  The aroma mist spray system according to Embodiment 1 of the present invention is sprayed by spraying pressurized aroma water in which pressurized water and essential oil are uniformly emulsified by a line mixer at a high pressure from a spray nozzle. Since the aroma mist has a particle size of 100 μm or less, the aroma mist instantly and uniformly diffuses in a very wide space, and as a result, the essential oil components contained in the aroma mist are uniformly distributed over a wide space. can do.
