Description

  The present invention relates to a heat storage device, a method for controlling an output temperature of the heat storage device, and a method for producing dry air.

  Conventionally, in order to effectively use heat energy, for example, surplus heat energy such as factory waste heat is stored in a heat storage tank with heat storage material and transported to a heat demand area, or to a demand area or facility within the same premises or nearby. Thus, a heat storage supply device using the stored heat energy has been proposed. This heat storage supply device includes, for example, a heat storage tank filled with a heat storage material, and a high-temperature gas is supplied to the heat storage material in the heat storage tank to cause a desorption reaction of the heat storage material to proceed, thereby storing heat, and utilizing the stored heat. In such a case, it was possible to supply high-temperature dry air by feeding wet air into the heat storage material in the heat storage tank, thereby promoting the adsorption reaction of the heat storage material and releasing heat.

  Patent Document 1 discloses a cold / hot heat supply device in which an adsorbent as the heat storage material is filled in a heat storage material filling tank. According to Patent Document 1, by sending dry high-temperature air to the adsorbent filled in the heat storage material filling tank, the adsorbent of the adsorbent is skipped to generate cold heat, By sending the adsorbent, the adsorbate adsorbs the adsorbate, and a heat radiation operation for generating heat can be performed. The cold heat generated in this manner is reformed to a desired temperature by a heat exchanger or a vaporizing cooler installed outside the heat storage tank, and is output as heat radiation.

  By the way, as an adsorbent used for this type of heat storage supply device, zeolite 13X, which is inexpensive to manufacture and easy to handle, is generally used. However, zeolite 13X requires dry air at a high temperature, for example, 130 ° C. or more during heat storage, and there is room for improvement in heat storage capacity.

  In this regard, an inorganic moisture-absorbing and desorbing material of a composite comprising amorphous aluminum silicate (HAS) and a low-crystalline layered clay mineral (Clay) having a trade name of “Husclay” is 80 Drying and heat storage with air at a relatively low temperature of not less than ° C. are possible, and a higher heat storage density than before is obtained. Therefore, it has been considered to use an adsorbent which realizes low-temperature drying and high heat storage density represented by this Haskley for this kind of heat storage supply device.

However, the adsorbent that realizes low-temperature drying and high heat storage density represented by the above-mentioned Hasclay has a problem that the temperature of dry air at the outlet side of the heat storage tank is not stabilized during heat release, and the peak sharply decreases. If the temperature of the dry air at the outlet side is not stable, there is a practical problem.
In the prior art described above, a specific measure for improvement of such a point is not disclosed, and low-temperature drying represented by Hasklay-radiation at the time of heat radiation when an adsorbent having realized a high heat storage density is used for a heat storage supply device. Measures have been awaited for stabilizing the temperature of the dry air on the outlet side.

  The present invention has been made in view of such a point, and in a heat storage supply device using an adsorbent that realizes a low-temperature drying-high heat storage density represented by Hasclay as a heat storage material, dry air on the outlet side during heat radiation is provided. It is intended to stabilize the temperature to solve the above-mentioned problem.

A heat storage and supply device for drawing dry air having a temperature higher than the temperature of the wet air from the side, characterized by having control means for controlling the temperature of the dry air.

According to the present invention, since the control means for controlling the temperature of the dry air derived from the outlet of the heat storage tank is provided, the temperature of the dry air can be controlled and stabilized.
The humid air referred to here is, for example, air having a relative humidity of 50% or more, and is not limited to air that is adjusted by actively adding moisture from outside, and may be outside air.

  The control means may be a flow rate adjusting mechanism for adjusting a flow rate of the humid air introduced into the heat storage tank.

  Further, the control means may be a humidity adjusting mechanism for adjusting the humidity of the humid air introduced into the heat storage tank.

  Furthermore, the control means may have a flow rate adjusting mechanism for adjusting the flow rate of the humid air introduced into the heat storage tank and a humidity adjusting mechanism for adjusting the humidity of the humid air introduced into the heat storage tank. That is, both the flow rate and humidity of the humid air introduced into the heat storage tank may be adjusted.

  The humidity adjusting mechanism mixes the first air having a relatively high humidity and the second air having a relatively low humidity, and adjusts a mixing ratio between the first air and the second air. It may have a function.

  The control unit may include a heat pipe unit that transports heat recovered from the dry air to the humid air.

  The control means may be a phase change material (PCM: Phase Change Materials) that changes its phase due to the heat of the dry air, and the phase change material may be provided on the outlet side of the heat storage tank.

  The plurality of types of control means described above may be arbitrarily combined as far as possible.

  According to another aspect, the present invention has a heat storage tank containing an adsorbent that generates heat by adsorbing adsorbate, and introduces humid air from an inlet side of the heat storage tank, and an outlet side of the heat storage tank. A method of controlling the output temperature of a heat storage supply device that derives dry air having a temperature higher than the temperature of the wet air from the above, wherein when the temperature of the dry air is higher than a predetermined value, the flow rate of the wet air is reduced. It is characterized by increasing.

  According to yet another aspect, the present invention has a heat storage tank containing an adsorbent that generates heat by adsorbing adsorbate, introducing humid air from an inlet side of the heat storage tank, and an outlet of the heat storage tank. A method for controlling the output temperature of a heat storage supply device that derives dry air having a temperature higher than the temperature of the wet air from the side, wherein when the temperature of the dry air is higher than a predetermined value, the humidity of the wet air Is characterized by lowering.

  The above-described two output temperature control methods may be combined.

  Furthermore, it can also be proposed to install the above-mentioned heat storage supply device in a place where the supply of the humid air can be secured, and to produce the dry air in the place.

  According to the present invention, in a heat storage supply device using an adsorbent as a heat storage material that realizes a low-temperature drying represented by Hasklay and a high heat storage density, the temperature of dry air on the outlet side during heat release is stabilized, and It is possible to increase.

  Hereinafter, embodiments of the present invention will be described. FIG. 1 schematically shows an outline of a system of a heat storage supply device 1 according to the embodiment. The heat storage supply device 1 includes a blow mixing unit 10 as a control unit and a heat storage tank 40.

  The air mixing section 10 has a housing shape as a whole, and the inside of the inlet side is partitioned and formed into a relatively high humidity area 20 and a relatively low humidity area 30. The relative high humidity area 20 is provided with an inlet 21 for introducing relatively high humidity air and a fan 22 for blowing the relatively high humidity air introduced from the inlet 21 to the heat storage tank 40.

The relative high humidity air from the fan 22 is sent to the mixing unit 11 through the duct 23. A damper D1 is provided at an outlet of the duct 23 to the mixing section 11.
Further, a temperature / humidity sensor 25 for detecting temperature / humidity is provided in the relative high humidity area 20, and a pressure sensor 26 for detecting pressure in the duct is provided in the duct 23.

  The relatively low humidity area 30 is provided with an inlet 31 for introducing relatively low humidity air, and a fan 32 for blowing the relatively low humidity air introduced from the inlet 31 to the heat storage tank 40.

The relative low humidity air from the fan 32 is sent to the mixing unit 11 through the duct 33. A damper D2 is provided at an outlet of the duct 33 to the mixing section 11.
Further, a temperature / humidity sensor 35 for detecting temperature / humidity is provided in the relative low humidity area 30, and a pressure sensor 36 for detecting pressure in the duct is provided in the duct 33.

  Each of the fans 22 and 32 is a fan that is controlled by an inverter. For example, a motor damper that is easy to control is used as the dampers D1 and D2. For example, the dampers D1 and D2 are based on the detection values of the pressure sensors 26 and 36 and / or the temperature and humidity sensors 25 and 35, or one of the values. Opening / closing control of D2 is performed. In such a case, the opening / closing control of the dampers D1 and D2 is performed so that the value detected by the temperature / humidity sensor 17 provided in the mixing unit 11 becomes a predetermined value. However, when the variation range of the relative high humidity air and the relative low humidity air introduced into the air mixing unit 10 is large, the opening and closing of the dampers D1 and D2 may be controlled by feedforward control.

  Then, the relatively high humidity air and the relatively low humidity air sent through the ducts 23 and 33 are mixed in the mixing unit 11, and are humid air having a predetermined relative humidity from the outlet 12 to the heat storage tank 40 through the duct 13. Is sent. The duct 13 is provided with a flow meter 14. The humidity and the amount of air supplied to the heat storage tank 40 are controlled, but are supplied to the heat storage tank 40 at a mixing ratio of the relative high humidity air introduced from the inlet 21 and the relative low humidity air introduced from the inlet 31. The humidity of the air is controlled. Further, the air volume of the mixed air is based on the indicated value of the flow meter 14, and is controlled by the inverter control of the fans 22 and 32 and the opening degree of the dampers D1 and D2 so that the air volume supplied to the heat storage tank 40 becomes a predetermined air volume. Controlled.

  The heat storage tank 40 has a filling section 42 that is vertically divided by a partition plate having air permeability and is filled with an adsorbent 41. Spaces 43 and 44 are provided above and below the filling section 42, respectively. The above-mentioned duct 13 is branched into three ducts 13a, 13b and 13c. The duct 13a communicates with the space 43 of the heat storage tank 40, the duct 13b communicates with the space 44 of the heat storage tank 40, and the duct 13c bypasses the heat storage tank 40. The space 43 is connected to the duct 15a, and the space 44 is connected to the duct 15b. Each duct 15a, 15b, 13c is connected to the duct 16.

  Each of the ducts 13a, 13b, 13c, 15a, 15b is provided with a corresponding damper D3-D7. For each of these dampers D3 to D7, for example, a motor damper that is easy to control is used. The heat storage supply device 1 has the above configuration.

  Next, an experimental operation example of the heat storage supply device 1 shown in FIG. 1 will be described. In this operation example, controls A to D described below and control as shown in FIG. 2 were performed. In the following operation example, the dampers D3 and D6 were opened, and the dampers D4, D5 and D7 were closed. Thereby, the humid air from the air mixing unit 10 is sent from the space 43 of the heat storage tank 40 to the filling unit 42, passes through the adsorbent 41 filled in the filling unit 42, and passes from the space 44 to the duct 15b, Through 16, it is sent to a demand destination for dry air.

  As the heat storage tank 40 used in this numerical analysis operation example, a rectangular heat storage tank was used, and about 160 L of an adsorbent Hasclay was filled therein as a heat storage material. During the heat storage operation, dry air having a temperature of 110 ° C. and a relative humidity of 0.2% was passed through the heat storage tank until it reached an equilibrium state, and then left until the heat storage material reached room temperature. In such an initial state, the following control was performed.

Control A: Until 9 hours have passed since the start of operation.
The opening of the damper D1 was 30%, and the opening of the damper D2 was 100%. The relative humidity of the humid air introduced into the heat storage tank 40 is 44%. The inlet temperature of the humid air introduced into the heat storage tank 40 is 25 ° C.
The flow rate of the humid air supplied to the heat storage tank 40 by the two fans 22 and 32 was kept constant at 100 m ³ / h.
Control B: Until a further 6 hours have passed since Control A.
The opening ratio of the damper D1 was set to 30%, and the opening ratio of the damper D2 was set to 70%, thereby reducing the mixing ratio of the relative low humidity air. The flow rate of the humid air supplied to the heat storage tank 40 by the two fans 22 and 32 was increased stepwise by 20 m ³ / h every hour to reach 250 m ³ / h. As a result, the relative humidity of the humid air introduced into the heat storage tank 40 gradually increased from 44%.
Control C: Until a further 5 hours have passed since Control B.
The opening ratio of the damper D1 was set to 50%, and the opening ratio of the damper D2 was set to 50%, thereby further reducing the mixing ratio of the relative low humidity air. The flow rate of the humid air supplied to the heat storage tank 40 by the two fans 22 and 32 was increased stepwise by 10 m ³ / h every hour to reach 300 m ³ / h. As a result, the relative humidity of the humid air introduced into the heat storage tank 40 was increased stepwise from 85%.
Control D: Until a further 7 hours have passed since Control C.
The opening degree of the damper D1 was set to 50%, and the opening degree of the damper D2 was set to 50%, which was the same as that in the control of C. The flow rate of the humid air supplied to the heat storage tank 40 by the two fans 22 and 32 was increased stepwise by 50 m ³ / h every hour to reach 600 m ³ / h. The relative humidity of the humid air introduced into the heat storage tank 40 is constant at 95%.

The change in the outlet-side temperature of the heat storage tank 40 in the above-described operation example, that is, the change in the outlet temperature and the output (calorific value) of the dry air led out of the duct 16 is as shown in the graph of FIG.
That is, the outlet temperature becomes constant at about 49 ° C. until 9 hours have passed since the start of the operation in which the control A was performed, and then gradually decreased until about 15 hours passed after the start of the operation in which the control B was performed, and reached about 38 ° C. became. Further, after the start of the operation in which the control C was performed, the decrease in the outlet temperature was reduced to about 35 ° C. until 20 hours passed. Thereafter, the rate of decrease in the outlet temperature became almost constant, and finally reached about 28 ° C.

  Generally, it is necessary for this type of heat storage supply device to obtain an outlet air having an inlet air temperature of + 10 ° C. in operation, but from this viewpoint, in the above-described operation example, as shown in FIG. In addition, the outlet air temperature of 35 ° C. or more is maintained for about 20 hours from the start of operation. On the other hand, the output, that is, the output (heat amount [kW]) on the outlet side of the dry air can be maintained at 0.8 [kW] even after 25 hours from the start of operation. Therefore, even when Hasclay was used as the adsorbent, the outlet temperature of the dry air could be stably maintained for a long time.

  The following is a comparison of such an effect with a conventional method, that is, a method in which the temperature of dry air on the outlet side is not controlled. First, the initial conditions were as follows. During the heat storage operation, dry air having a temperature of 110 ° C. and a relative humidity of 0.2% was passed through the heat storage tank for 3 hours and left at room temperature for 3 days. The size of the heat storage tank 40 is a cylindrical heat storage tank having a filling portion of about 2 L. The temperature of the humid air introduced into the heat storage tank during the heat dissipation operation is 25 ° C., and the relative humidity is 96%. FIG. 4 is a graph showing the change over time in the temperature of the dry air derived from the heat storage tank, with the introduced air flow at 250 L / min.

  According to this, the temperature was high at about 75 ° C. at the time of the peak immediately after the start of operation, but the temperature rapidly decreased with the lapse of time. ° C.

  As is apparent from these results, the operation control at the time of heat release by the heat storage supply device according to the embodiment, that is, the flow rate control of the wet air introduced into the heat storage tank 40 and the humidity control are performed, so that the outlet side of the heat storage tank 40 is controlled. It can be seen that the temperature of the dry air can be stably maintained for a long time.

In the above-described numerical analysis operation example, both the flow rate and the humidity of the wet air are controlled. However, only the humidity of the wet air or the flow rate of the wet air is controlled. The temperature can be maintained stably. That is, when the temperature of the dry air on the outlet side of the heat storage tank is higher than the predetermined value, the outlet temperature of the dry air is stabilized by performing control to reduce the relative humidity of the wet air introduced into the heat storage tank. Can be maintained. In this case, when the temperature of the dry air is lower than a predetermined value, it is possible to obtain an appropriate outlet temperature of the dry air at the time of heat radiation by increasing the relative humidity of the wet air.
By controlling the relative humidity of the wet air in this way, the temperature of the dry air can be easily controlled. The controllable range is determined by the state of the relatively high humidity first air and the relatively low humidity second air.
When the temperature of the dry air at the outlet of the heat storage tank is higher than a predetermined value, the output (kw) of the dry air can be easily controlled by increasing the flow rate of the wet air introduced into the heat storage tank. It is. However, the temperature of the dry air cannot be increased.

As described above, in controlling the humidity of the wet air, the outlet temperature of the dry air can be increased or decreased. However, it is a condition that two types of air having different humidity are obtained. On the other hand, with respect to the flow rate control, since it is only necessary to control the output of the fan, the control itself is easy, and thereby it is easy to adjust the rate of decrease in the outlet temperature of the dry air. However, the temperature of the dry air on the outlet side cannot be increased only by the flow rate control.
However, it is possible to stabilize the outlet temperature based on only one of the controls.

  In the heat storage supply device 1 according to the above-described embodiment, when the relative high humidity air and the relatively low humidity air are introduced and mixed in the mixing unit 11 and sent to the heat storage tank 40, the individual fans 22 and Although 32 was used, as shown in FIG. 4, the introduction of relatively high-humidity air and relatively low-humidity air into the blast mixing unit 10 and the blowing of heat to the heat storage tank 40 are performed by one fan 51. Then, the humidity and flow rate of the humid air introduced into the heat storage tank 40 may be adjusted.

  That is, in the heat storage supply device 1 shown in FIG. 5, the fans 22 and 23 used in the heat storage supply device 1 shown in FIG. 1 are removed, and instead, the duct 13 outside the air mixing unit 10 is provided. The fan 51 is provided. With this configuration, it is also possible to send mixed air of relatively high-humidity air and relatively low-humidity air to the heat storage tank 40, and to control the opening and closing of the dampers D1 and D2 to store the humid air of the desired humidity in the heat storage tank 40. It can be introduced into the tank 40.

  Further, in the heat storage supply device 1 shown in FIG. 1, the air mixing unit 10 as a control means includes a fan 22, ducts 23, 33, dampers D1, D2, and a mixing unit 11 in one housing. However, the present invention is not limited to such a box-shaped blast mixing unit 10, and a blast mixing unit as a control unit may be constructed by a simple duct, a damper, or the like. By doing so, it is possible to construct and install the blast mixing unit 10 as a control means even in a narrow place where piping and the like are complicated.

  In the above-described embodiment, the air mixing unit 10 is employed as the control means, but a control means having a heat pipe 61 as shown in FIG. 6 may be used instead.

  That is, in this example, the heat pipe 61 has a configuration in which both ends of the heat pipe 61 are obliquely extended, for example, between a flow path 62 communicating with the lower space 43 of the heat storage tank 40 and a flow path 63 communicating with the upper space. ing. In such a case, the low-temperature wet air is introduced into the flow path 63, passes the adsorbent 41 from the space 44, and draws out the dry air from the space 43 through the flow path 62.

  By passing the heat pipe 61 to the flow paths 62 and 63 in this way, the working fluid in the heat pipe 61 absorbs heat and evaporates due to the temperature of the dry air flowing in the flow path 62, and the vapor of the working fluid is vaporized. Moves upward through the space in the heat pipe 61. Since the moist air flowing through the flow path 63 has a lower temperature than the dry air, the vapor of the working fluid that has moved upwards is condensed into a liquid. Then, the working fluid that has become liquid moves downward along the inner wall of the heat pipe 61, and the working fluid in the heat pipe 61 absorbs heat and evaporates due to the temperature of the dry air flowing through the flow path 62 again. I do. By such a process, heat is recovered from the dry air flowing through the flow path 62, and the recovered heat is transported to the wet air flowing through the flow path 63.

  Due to such heat transfer, the temperature of the hot dry air in the flow path 62 is reduced. On the other hand, since the temperature of the humid air flowing through the flow channel 63 rises, the relative humidity decreases. Thereby, the reaction of the adsorbent 41 in the heat storage tank 40 is suppressed. Therefore, although the peak value of the temperature of the dry air on the outlet side decreases, a stable temperature can be maintained for a long time.

  If the temperature of the dry air in the flow path 62 is low, the temperature of the humid air introduced into the heat storage tank 40 from the flow path 62 by the action of the heat pipe 61 is reduced, thereby reducing the relative humidity of the humid air. To rise. As a result, the reaction in the adsorbent 41 in the heat storage tank 40 is promoted, and the temperature of the dry air derived from the flow path 62 is increased and corrected. Thereby, the temperature of the dry air derived from the heat storage tank 40 becomes stable.

  In the example illustrated in FIG. 6, the heat pipe 61 is configured to extend between the flow paths 62 and 63. However, the heat pipe 61 may be provided in the heat storage tank 40. For example, the heat storage tank 40 may be provided between the spaces 43 and 44. In addition, the heat pipe 61 may be provided so as to be embedded in the adsorbent 41 of the filling section 42 in the heat storage tank 40. In these cases, the heat pipe 61 may be arranged obliquely or vertically.

  Further, instead of the heat pipe 61, as shown in FIG. 7, a PCM which is a phase change material that changes its phase by the heat of the dry air is housed in a flow path 63 on the outlet side of the heat storage tank 40 from which the dry air flows. PCM device 71 may be provided. In FIG. 7, it is set so that wet air is introduced into the heat storage tank 40 from the flow path 62, and dry air after the reaction by the adsorbent 41 is drawn out from the flow path 63. The PCM device 71 is configured such that, for example, a PCM is housed in a housing, the housing is installed in the flow channel 63, and dry air flowing through the flow channel 63 flows through the PCM in the housing. I have.

  Since the PCM device 71 is provided in the flow path 63 on the outlet side of the heat storage tank 40 from which the dry air is drawn out, the phase change material in the PCM device 71 is dried by being heated. In this case, the heat is used, so that the temperature of the high-temperature dry air derived from the flow path 63 gradually decreases. Although the peak value is lowered by this, the temperature of the dry air derived from the heat storage tank 40 becomes stable.

  In the example of FIG. 7, the PCM that is a phase change material is housed in the PCM device 71 and provided in the channel 63 outside the heat storage tank 40, so that the PCM device 71 is installed, removed when unnecessary, or The setting of the bypass flow path is easy. However, the present invention is not limited to this, and may of course be installed in the space 43 in the heat storage tank 40. In short, the PCM device 71 may be provided on the downstream side of the adsorbent 41 during heat radiation.

  When the PCM device 71 is provided, the reaction of the adsorbent 41 decreases when the outlet temperature of the heat storage tank 40 decreases. Then, the moist air introduced into the heat storage tank 40 passes through the adsorbent 41 of the heat storage tank 40 and reaches the phase change material in the PCM device 71, so that the phase change material starts a reaction and the PCM device 71 The temperature of the derived dry air rises. Therefore, from this point, when the PCM device 71 is installed, the temperature of the dry air at the outlet side of the heat storage tank 40 is stable.

  The PCM device 71 may be installed or removed when not needed, for example, during heat storage and installed during heat dissipation. For example, when the heat storage tank 40 after the heat storage is transferred to another place for operation, the PCM device 71 is removed, or the PCM device 71 is prepared in advance at the transfer place, and the heat dissipation operation is performed at the transfer place. Before starting, the PCM device 71 may be installed on site. This facilitates transportation of the heat storage tank 40 itself. Also, when there is a considerable time between the heat storage operation and the heat dissipation operation, the PCM device 71 may be removed and stored in another storage place. By doing so, the maintenance required for the PCM device 71 can be minimized, and the phase change material in the PCM device 71 can be stored in an appropriate temperature and humidity environment.

  Further, the above-described heat pipe 61 and PCM device 71 may be used in appropriate combination, and may be implemented in combination with the above-described humidity control and flow rate control of wet air. As a result, the control range can be widened, and the temperature of the dry air during the heat dissipation operation can be maintained more appropriately and for a long time.

  The heat storage supply device according to the above-described embodiment can produce dry air at a place where humid air can be secured and supply it to a demand destination. Therefore, after the heat storage operation is performed by receiving the supply of the high-temperature air during the heat storage, the supply of the high-temperature air is performed by transferring, for example, the heat storage tank 40, which can be regarded as a main device, and the blast mixing unit 10 to a place where the wet air can be secured. It is possible to easily produce dry air required by a demand destination and supply the dry air to a demand destination at a location away from a place where the user is located.

  From this point of view, by making the above-mentioned PCM device 71 removable and installable, the heat storage tank 40 itself can be easily transported and can be constructed as a versatile device.
