Description

  This invention can be used, for example, by cooling a hot spring hot enough to prevent bathing as it is, a waste liquid used as a cooling liquid in a power plant or factory, a cooling liquid used in machining, and the like. The present invention relates to a high-temperature liquid cooling device that facilitates discharge and the like. In the present invention, the “hot liquid” means a liquid that is hot to be used, and whether or not it is high depends on the type of liquid, application, and the like.

  As an example of the high-temperature liquid, the case of a high hot spring that springs out at a high temperature will be described. Since the high hot spring cannot be bathed as it is, that is, at 100% of the source spring, a method of adding water and cooling is adopted.

  However, in order to add water, there is a problem that water charges and facilities for that are expensive. On top of that, apart from hot springs that cannot be bathed without adding water because of the large amount of deposits, such as the gold springs of Arima Onsen, generally the hot spring components are diluted if cooled with water, and the effectiveness of the hot spring is reduced. Resulting in.

  Also, instead of adding water, the hot springs were cooled by shallowing the bathtub, such as Shirahama hot springs in Wakayama Prefecture, which are known as non-volcanic high hot springs. However, in this case, there are problems such as difficulty in temperature control. As a similar method, there is a method using a hot water tank, an aeration tank, a hot water reservoir, or a hot water field, but there is a negative aspect such that it takes time for cooling. In addition, there is a method using a heat exchanger or a cooling tower, but there are cases where it cannot be used depending on the quality of the spring, and there is a problem that a running cost such as maintenance is high.

  For this reason, a hot spring cooling device as disclosed in Patent Document 1 below has been devised. This device drops hot springs that are hotter than the surrounding temperature onto the branches of plants such as bamboo and trees, drops the hot springs along the branches, and removes the heat of vaporization from the hot springs. The hot spring is cooled by exchanging heat. According to this apparatus, the hot spring can be cooled in a short time without diluting the components.

  However, since this apparatus performs vaporization and heat exchange in the atmosphere, it is directly affected by the temperature and humidity of the atmosphere, the ambient wind, and the like. For this reason, it is difficult to set an appropriate temperature regardless of atmospheric conditions.

Registered Utility Model No. 3112971

  Therefore, the main object of the present invention is to enable cooling that does not depend on water to be performed appropriately while suppressing the influence of the atmosphere.

  The means for that is a high-temperature liquid cooling device that cools the high-temperature liquid by dropping the high-temperature liquid, bringing the dropped liquid into contact with the filter, and vaporizing the dropped liquid and exchanging heat with the atmosphere. A high-temperature liquid cooling apparatus in which a plurality of the filters are housed in a vertical direction with a gap between each other in a casing that separates from the outside air, and provided with fluid means for flowing the atmosphere between the filters. .

  The dripping liquid of the high-temperature liquid dropped on the filter in the housing is divided and made finer by contacting the filter, and heat exchange is performed with the atmosphere in the housing, and the state becomes easy to vaporize. And by vaporization, it becomes the dripping liquid which temperature fell from before and falls further. In the process of falling, the heat exchange and vaporization are further performed, and the heat exchange and vaporization are performed in the same manner as described above by sequentially contacting another filter arranged below, and the temperature of the high temperature liquid is lowered. To do.

  At this time, since the atmosphere flows between the filters by the action of the flow means, the atmosphere positively contacts the dropped liquid by the flow means during the period from the upper filter to the lower filter. For this reason, the atmosphere flows without stagnation, vaporization and heat exchange are promoted, and cooling can be performed reliably.

  Such temperature reduction (temperature reduction) processing is performed by discharging the atmosphere (steam) from the upper end of the casing so that the steam in the casing does not reach saturation, and if necessary, The temperature is cooled by appropriate cooling means, or a large amount of outside air is taken in to promote vaporization and heat exchange.

  Since the processing is performed in the housing, conditions such as the temperature and humidity of the atmosphere in the housing are appropriately set in relation to the temperature and amount of the high-temperature liquid and the temperature and humidity conditions of the atmosphere (atmosphere) outside the housing. Thus, a desired temperature drop can be realized while suppressing the influence of the atmosphere.

  As described above, according to the present invention, desired cooling can be performed without being directly affected by the atmosphere without adding water.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a cross-sectional view showing a schematic structure of a high-temperature liquid cooling device 11 (hereinafter referred to as “device”) suitable for cooling a high hot spring to a temperature suitable for bathing. 2 is a front view, FIG. 3 is a rear view, and FIG. 4 is a side view.

  As shown in these drawings, the device 11 has a substantially rectangular parallelepiped box shape, cools while dropping a high-temperature liquid such as a high hot spring introduced from the upper part, and discharges it from the lower part. Cooling is performed by evaporating the dripping liquid dripped and heat-exchange between atmosphere.

  The apparatus 11 has a rectangular parallelepiped casing 21, and receives and diffuses into the casing 21 a high temperature liquid introduction pipe 31 that introduces a high temperature liquid and a high temperature liquid that flows down from the high temperature liquid introduction pipe 31. Diffusing plate 41 to be dropped, a plurality of filters 51 disposed below the diffusing plate 41, flow means 61 for forcibly flowing the atmosphere in the casing 21 including the space between the filters 51, and the filter And a liquid receiving tank 71 for receiving the dropped liquid dropped through 51.

  The high-temperature liquid introduction pipe 31 introduces a high-temperature liquid (source) pumped up by a pump or a trumpet pipe, and is attached so that the introduction port 32 rises from the side surface on the front side of the apparatus 11. And in the housing | casing 21, it has extended toward the center part of the left-right direction at the front side, and the front-end | tip part is extended toward the intermediate position of the front-back direction slightly, then bends downward, A flow-down port 33 through which the liquid flows down is provided.

The diffusion plate 41 is provided below the flow-down port 33.
As shown in FIG. 5, the diffusion plate 41 is a thin dish having a rectangular shape in plan view, and the size in the front-rear direction is set to about two-thirds of the length in the front-rear direction of the housing 21. The range in which the high temperature liquid is dripped in the body 21 is limited.

  As shown in FIG. 6, the diffusion plate 41 has a plurality of partition portions 42 on the surface and a plurality of through holes 43 penetrating in the thickness direction. The partition part 42 is a linear bulge that exists intermittently without contacting each other, and is appropriately arranged so that an independent space surrounded by the partition part 42 is not formed. This partition part 42 contributes to spreading to the corner of the diffusion plate 41 while dispersing the high-temperature liquid that has flowed down. The plan view shape of the partition portion 42 may be formed in a flat and substantially rhombus shape as illustrated. The through hole 43 is appropriately formed in a portion that does not overlap the partition portion 42.

  Further, a peripheral wall 44 is formed around the diffusion plate 41 as shown in FIG. 5, and the surface center of the diffusion plate 41, which is a plane that rises higher than the surroundings at a portion corresponding to the flow-down port 33. A raised portion 45 having a circular shape is formed. The surface of the raised portion 45 is preferably formed as a flat surface, but may have other shapes. Due to the presence of the raised portion 45, the flowing high temperature liquid first hits the raised portion 45, which can contribute to the diffusion of the high temperature liquid. In FIG. 5, 44 a is an attachment portion for attachment to the inside of the casing 21.

  Specifically, a so-called checker plate may be used for manufacturing the diffusion plate 41. The diffusion plate 41 can be obtained simply by forming the through hole 43 and bending it.

  The filter 51 is for subdividing the dropped dripping liquid to facilitate vaporization and heat exchange. The plurality of filters 51 are arranged vertically by the support device 55 with a gap between them, and are detachably held. The arrangement may be performed so that the filter 51 is horizontal, but in this example, the case is shown in which all are inclined in the same direction. That is, as shown in FIG. 1, the three filters 51 are arranged in the vertical direction in a state where they are inclined so as to face downward toward the tip side. The inclination is an inclination in the front-rear direction of the device 11, and is set higher on the front side and lower on the rear side.

  The three filters 51 are held with different lengths and angles with respect to the vertical direction. Specifically, as shown in FIG. 7, among the three filters 51..., The middle one is formed longer than the upper one (L1 <L2), and the upper one of the three filters 51. The middle one has the same angle α with respect to the vertical direction, while the lower one is set to an angle β larger than the angle α. Since the angle β of the lower filter 51 is larger than the angle α of the other filters 51, the length L3 of the lower filter 51 is formed shorter than the length L2 of the middle filter 51 so as to be accommodated in the housing 21. Has been.

  Thus, by making a difference in length and angle, the drop liquid can be subdivided efficiently.

  The support device 55 is hung on two frame members 56, 56 having a U-shaped longitudinal cross-section to hold the left and right edges of the filter 51, and the lower surfaces of the rear ends of these frame members 56, 56. A pivot shaft 57 to be passed, a receiving portion 58 formed on the casing 21 to receive both ends of the pivot shaft 57 so as to be rotatable and detachable, and a support column 59 erected in the casing 21. And a support shaft 59a that supports the distal end side of the frame member 56. In FIG. 7 and FIG. 1, 59b provided below the lowermost support shaft 59a and above the liquid receiving tank 71 is an air injection shaft having the same structure as the support shaft 59a.

  As shown in FIG. 8, the filter 51 is formed in a rectangular mat shape having a thickness that allows both left and right edges to fit in the frame member 56, and is held between the frame members 56 and 56. The angle of the frame member 56, that is, the angle of the filter 51 can be changed by changing the manner in which the frame member 56 is supported with respect to the support shaft 59a. As shown by the solid line in FIG. 7, when the frame member 56 is mounted on the support shaft 59a, the angle α increases, and conversely, when the frame member 56 is mounted below the support shaft 59a, the angle α decreases. When the frame member 56 is supported on the support shaft 59a, it may be simply placed on the support shaft 59a. When the frame member 56 is supported under the support shaft 59a, for example, a U-shaped hook or the like is used. Just hook it.

  Although an appropriate material can be used for the filter 51, in this example, the thing using bamboo is demonstrated.

  As the bamboo, an appropriate material such as a bamboo shoot can be used, and a branch and leaf portion on the tip side, that is, a portion having a large number of branch-like portions branching toward the tip side is used. In use, a suitable number of portions having branch-like portions are bundled, and the bamboo bundle 52 is arranged in the left-right direction so that the tip side of the bamboo is located on the tip side of the filter 51 to form a mat. To form a mat, a plurality of bundles are vertically sandwiched between rectangular net members 53, 53 as shown in FIG. Although not shown, the mesh member 53 is provided with appropriate hooks and the like, and is held so as not to be separated with the bamboo bundle 52 sandwiched therebetween.

  In addition to bamboo, for example, the filter 51 is formed by compressing the bark of a tree such as cedar, mats, fibers of palm, cellulose, ceramics, etc., synthetic resin, etc. In accordance with the properties (spring quality) of the high-temperature liquid, such as those prepared, it can be appropriately selected and used.

  The flow means 61 is composed of air injection means for injecting outside air (atmosphere) outside the housing 21 so as to cause the atmosphere to flow upward of the inclined filter 51. That is, it has the intake fan 62, the support post 59 connected to the intake fan 62, the support shaft 59a and the air injection shaft 59b installed on the support post 59, and the support shaft 59a and the air injection shaft 59b. In addition, nozzle holes 63 and 64 are formed as air injection means.

  The intake fan 62 is provided with an intake pipe 62a facing the intake window portion 22 formed on both left and right side surfaces of the casing 21, and outside air outside the casing 21 is sucked from the intake pipe 62a. The nozzle holes 63 and 64 are formed at an obliquely upper position facing the upper side of the filter 51 and a position immediately below (see FIG. 10). The nozzle hole 64 formed at the position immediately below ejects the liquid (dropped liquid) into the support shaft 59a or the air ejection shaft 59b, and the liquid is ejected into the support shaft 59a or the air ejection shaft 59b. Prevent accumulation. In addition, when the liquid accumulated in the support shaft 59a or the air injection shaft 59b is ejected, it is ejected in the form of a mist, so that vaporization and heat exchange are easily performed.

  As shown in FIG. 11, without using the support shaft 59a and the flow means 61, the support shaft 59c for only the filter support and the injection pipe 65 for air injection are provided on the support column 59. Can also be added. In this case, the injection pipe 65 can be provided at an intermediate position of the gap between the filters 51.

  The liquid receiving tank 71 has an inclined plate portion 71a for allowing the intake fan 62 to be accommodated, and discharges the collected liquid to be cooled, because the intake fan 62 is provided at the bottom on the front side in the casing 21. A discharge pipe 72 is provided.

  As shown in FIG. 2, doors 23 and 23 that can be opened and closed are provided on the front surface of the housing 21 so that the filters 51 can be attached and detached, maintained, and the like.

  Further, appropriate vent holes 24 are formed in the front surface of the housing 21 including the door body 23 and the lower portion of the back surface of the housing 21 as shown in FIGS. The vent hole 24 may be formed by cutting and raising as shown in FIG. In FIG. 1 and FIG. 3, reference numeral 25 denotes a cover for concealing the air hole group formed by dividing the block into five blocks so as not to be seen from the outer surface. Is formed.

  Further, an exhaust port 26 is formed on the upper surface of the casing 21 as shown in FIG. 1, and an exhaust fan 27 is provided above the exhaust port 26. That is, by rotating the exhaust fan 27, the atmosphere in the housing 21 is forcibly discharged, and the housing 21 is prevented from being saturated. In the figure, 28 is a hood whose upper surface is open.

  A base hood having an upper surface opening that covers the side of the exhaust fan 27 may be provided between the exhaust port 26 and the hood 28. Thereby, it is possible to prevent the exhaust efficiency of the exhaust fan 27 from being lowered due to the turbulence of the airflow between the outside air near the exhaust port 26 and the exhausted atmosphere.

  In the apparatus 11 configured as described above, the high temperature liquid is cooled as follows.

  First, the intake fan 62 and the exhaust fan 27 are driven. Then, a high temperature liquid is passed through the high temperature liquid introduction pipe 31. Then, the high-temperature liquid that has entered from the high-temperature liquid introduction pipe 31 flows onto the diffusion plate 41 and drops while diffusing in a certain range by the diffusion plate 41. The dropped liquid drops fall on the filter 51 as shown in FIG. 1. In the filter 51, the dropped liquid is subdivided and falls along the branches obliquely downward, and the support shaft 59a and the air jet It is exposed to the outside air outside the casing 21 injected from the shaft 59 b and the atmosphere inside the casing 21 that is attracted to and flows, and further falls and falls to the filter 51 in the next stage. While dropping in this way, the dripping liquid is vaporized as schematically shown in FIG. At the same time, heat exchange with the atmosphere present in the housing 21 is performed. Vaporization and heat exchange are continuously performed, and the dripping liquid is gradually cooled.

  At this time, the exhaust fan 27 can be driven to prevent the inside of the casing 21 from being saturated, vaporization can be maintained, and vaporization is promoted by flowing outside air sucked from the intake fan 62 between the filters 51. At the same time, exhaust the atmosphere. In addition, the temperature of the atmosphere inside the casing 21 is lowered by driving the exhaust fan 27 and the intake fan 62 and sucking outside air outside the casing 21 through the vent hole 24. In this manner, the high temperature liquid is cooled while the vaporization and heat exchange of the dropped liquid are maintained.

  The cooled liquid to be cooled is led out of the apparatus 11 from the liquid receiving tank 71 through the discharge pipe 72 and used at an appropriate location such as a bathtub.

When a high temperature hot spring cooling experiment was performed using the apparatus 11 in which the casing 21 was made of stainless steel, the experimental results shown in Table 1 below were obtained. The experiment was performed twice, and each experiment flowed into the high temperature hot springs shown in the upper part of Table 1 and measured the discharge temperature from the discharge pipe 72. Experiment NO. The experimental conditions of No. 1 are an outside air temperature of 29 ° C., an outside air humidity of 75%, and a flow rate of 50 L / min. The experimental conditions of 2 were an outside air temperature of 34 degrees, an outside air humidity of 50%, and a flow rate of 50 L / min. The volume of the casing 21 is approximately 3.6 m ³ .

上記表１からも分かるように、装置１１は、外気温に影響されず、高温液の温度を迅速に冷却できることが判明した。

As can be seen from Table 1 above, it has been found that the apparatus 11 can quickly cool the temperature of the high-temperature liquid without being affected by the outside air temperature.

  In addition, since the cooling process of the high-temperature liquid is performed in the housing 21, it can be performed without being directly affected by the outside air, and stable and reliable cooling is possible. In addition, the conditions such as the temperature and humidity of the atmosphere in the housing 21 are appropriately set in relation to the temperature and amount of the high-temperature liquid and the temperature and humidity conditions of the atmosphere (outside air, air) outside the housing 21. Thus, a desired temperature drop can be realized.

  Moreover, since all the three filters 51 are inclined in the same direction, the apparatus 11 can be configured compactly.

  In addition, if it does as shown in FIG. 13, vaporization and heat exchange can be promoted more. FIG. 13A shows an example in which a cooling means such as a well-known air cooler 81 that generates low-temperature air, for example, by generating eddy currents is attached to the temperature in the housing 21, and is an example that mainly promotes heat exchange. FIG. 13B is an example in which compressed air is supplied into the casing 21 by using a compressed air generator 82 that generates curtain-like compressed air to mainly promote vaporization. When curtain-like compressed air is supplied, air outside the casing 21 is also attracted, so that a large amount of outside air having a lower temperature than the atmosphere inside the casing 21 can be supplied.

Other examples will be described below. In the description, the same or equivalent parts as those in the previous configuration are denoted by the same reference numerals, and detailed description thereof is omitted.
FIG. 14 shows an example in which the filter 51 is arranged horizontally. That is, the inside of the housing 21 is conceptually divided into two in the front-rear direction, a high temperature liquid introduction pipe 31 for introducing a high temperature liquid is provided on one upper surface, and an exhaust port 26 and an exhaust fan 27 are provided on the other upper surface. Yes. A diffusion plate 41 and a plurality of filters 51 are disposed below the high-temperature liquid introduction pipe 31 with appropriate gaps. Further, on the back side of the portion where the diffusion plate 41 and the filter 51 are accommodated, a blower 91 is provided as a flow means for sending the atmosphere between the diffusion plate 41 and the filter 51 and the filter 51. ing. A cooling element 92 having both air permeability and water retention, such as a cellulose pad, is disposed on the intake side (right side of FIG. 14) of the blower 91, and further, water can be passed from above to the cooling element 92. A water injection facility 93 is provided. Thereby, since the external air sent in in the housing | casing 21 passes through the cooling element 92 which is a wet state with the water injection equipment 93, and is sent in in the housing | casing 21, the cooling effect can be improved more.

  In the apparatus 11 having such a configuration, the same applies to the apparatus 11 in the above example. However, if the apparatus 11 exists as one unit, it depends on the flow rate of the high-temperature liquid to be processed, the processing capacity of the apparatus 11, the outside air conditions, and the like. Thus, the number of devices 11 can be increased or decreased as shown in FIG. 15, and as a result, desired cooling can be easily realized.

The flow means of this invention corresponds to the nozzle holes 63 and 64 or the blower 91 in the above configuration,
Similarly,
The air injection means corresponds to the injection holes 63 and 64,
