  The four front, rear, left and right side surfaces of the cooling tower 61 are covered with four heat shield plates 62 so as to have a rectangular cylindrical shape, as shown in FIGS.

  Of the four heat shield plates 62, for example, the front heat shield plate 62 has a control for controlling the entire hot spring steam power generation / hot water making unit 2 and monitoring the operation, as shown in FIGS. A monitoring panel 63 is provided.

  As shown in FIGS. 4 to 8, a cooling tower main body 71 having a cube shape is arranged inside four rectangular heat shield plates 62 of the cooling tower 61.

  The cooling tower body 71 has a rectangular box-shaped housing 72 having a hollow interior, a hot spring steam intake pipe 73 provided at, for example, an upper front side of the housing 72, and an upper surface portion of the housing 72. , A hot water discharge pipe 75 provided on, for example, a lower surface of the housing 72, and the front and rear left and right surfaces of the housing 72 inside the heat shield plate 62.

  Further, the cooling tower fan 18 is configured to rotate based on the power generated by the thermoelectric conversion element unit 14.

  FIG. 9 illustrates a block configuration of a power generation system in the hot spring steam power generation / hot water making system 1 of the present embodiment. The power generation system includes a thermoelectric conversion element unit 14 that generates power based on hot spring steam, a cooling element unit 17, , A power storage unit 22 for storing power generated from the thermoelectric conversion element unit 14 (DC power), and a power generated from the thermoelectric conversion element unit 14 (DC power) or from the power storage unit 22.

I have.

  FIG. 10 shows the arrangement of the thermoelectric conversion element unit 14, the wall 72a (high temperature side) of the housing 72, and the heat sink 16 (low temperature side).

  Next, the operation of the hot spring steam power generation / hot water making system 1 according to the present embodiment will be described.

In the hot spring steam power generation / hot water making system 1 according to the present embodiment,
(1) Hot spring steam is allowed to flow in from the flow path piping section 3.

(2) The inside of the thermoelectric conversion / cooling unit 11 becomes high temperature (about 100 ° C.) by flowing hot spring steam.

(3) That is, the inner surface of the thermoelectric conversion element unit 14 (thermoglycol) installed in the thermoelectric conversion / cooling unit 11 has a high temperature (about 100 ° C.).

(4) Further, the outer surface side of the heat sink 16, which is the cooling element unit 17 outside the thermoelectric conversion element unit 14, is cooled by the cooling tower fan 18, whereby a temperature difference (Δt) is generated on both sides of the thermoelectric conversion element unit 14. .

  For example, if the outside air temperature is 30 ° C., a temperature difference of Δt = 70 ° C. occurs due to forced cooling.

(5) Due to this temperature difference (Δt), current starts to flow in the thermoelectric conversion element unit 14 and power generation based on hot spring steam is started (the amount of power generation [power: voltage and current] increases and decreases according to the value of Δt). .

  At the same time, the steam in the thermoelectric conversion / cooling unit 11 is cooled to become hot water (hot spring water) and is discharged downward from the hot water discharge pipe system 4, and is used as hot water as in the conventional case. .

(6) Since the hot spring steam is blown out without interruption, the steam is not shown, but the inside of the thermoelectric conversion / cooling unit 11 is kept at a constant high temperature unless stopped by a valve, and the outside of the thermoelectric conversion element unit 14 is a cooling tower fan. Cooling is performed by air cooling by 76 (or heat of vaporization by mist-like liquid spray or water cooling), but the temperature difference (Δt) varies depending on the cooling capacity.

(7) Here, it is necessary to control the temperature inside and outside the thermoelectric conversion / cooling unit 11, but the present apparatus is provided with a temperature sensor for monitoring the inside and outside of the thermoelectric conversion / cooling unit 11, and performs monitoring. Is fed back to the control / measurement unit 21 to control the cooling function of the cooling tower fan 76 and the like. As a result, a constant temperature difference (Δt) is always maintained, and stable power supply is enabled.

(8) Although the power generated by the thermoelectric conversion / cooling unit 11 is DC power, the generated DC power is converted by the AC power supply unit 23 into AC power of the same single-phase AC 100 V as the commercial power supply. This AC power can be used for general lighting equipment and home appliances.

(9) It is of course possible to install a power storage function in order to maintain more stable generated power.

  Next, the power generation capacity of the hot spring steam power generation / hot water making system 1 according to the present embodiment will be described.

  The power generation capacity of the hot spring steam power generation / hot water production system 1 of the present embodiment depends on the inside / outside temperature difference (Δt) of the thermoelectric conversion element unit 14 and the installation area thereof.

  As the temperature range, power can be generated with a temperature difference (Δt) of 3 ° C. to 80 ° C., but preferably, the temperature difference (Δt) = 60 ° C. to 70 ° C.

  In order to maintain the most efficient temperature difference (△ t), the outer cooling mechanism is important, depending on the temperature and flow rate of hot spring steam, such as natural air cooling, forced air cooling, mist spray cooling, water cooling, etc. An optimal cooling method can be selected from such cooling methods.

  The standard power generation capacity is 10500 Wh (10.5 kWh) at 36 V DC (direct current (DC)) and 100 V single-phase AC via the AC power supply unit 23 when the temperature difference Δt is 70 ° C. Although a maximum of about 9000 Wh (9 kWh) is possible, it depends on the temperature difference (Δt), size (power generation area), and the like.

  FIGS. 12 and 13 show a plurality (for example, two) of hot spring steam power generation / hot water making units 2 including the thermoelectric conversion / cooling unit 11 shown in FIG. 11 connected in parallel (FIG. 12), or a plurality (for example, 2). FIG. 13 shows a configuration for increasing the amount of power generation and the amount of hot water produced by the thermoelectric conversion / cooling unit 11 in series (cascade) (FIG. 13). It should be noted that the number of stages of the hot spring steam power generation / hot water making unit 2 may be two, three, four, or more.

  Next, a specific example of the thermoelectric conversion / cooling unit 11 will be described with reference to FIGS.

  That is, as shown in FIG. 14 to FIG. 17, the thermoelectric conversion / cooling unit 11 is a part of the hot spring steam flow path piping portion 3 arranged on the hot spring steam power generation / hot water making unit 2 side. The hot spring steam is received from the inlet pipe section 12, the hot spring steam is circulated in the hot spring steam distribution box section 13 in the unit, and further circulated toward the surplus hot spring steam discharge pipe system 5.

A cooling element unit 17 using a number of heat sinks 16 for converting a part of the hot spring steam into hot spring water (cooling) and discharging it as hot water.

  For example, as shown in FIG. 18, the thermoelectric conversion element unit 14 is formed by, for example, forming a seebeck element 15 formed in a film shape in three continuous units and integrating them, and the hot spring steam distribution box part in the unit 13 are arranged in a paired configuration sandwiched between both outer wall surfaces 13 and the heat sinks 16 on both outer sides thereof.

  The thermoelectric conversion element unit 14 utilizes a temperature difference between a temperature based on heat transferred by hot spring steam flowing in the hot spring steam distribution box 13 in the unit and a temperature of, for example, an outside air temperature transmitted through the heat sink 16. In this way, a power generation output is obtained.

  Next, a test system 51 for testing power generation performance based on steam of the hot spring steam power generation / hot water making system 1 according to the present embodiment will be described with reference to FIGS.

This is configured to transmit the generated hot water to the thermoelectric conversion / cooling unit 11A via a drain pipe 56 for discharging hot water.

And the load: the relationship between the generated voltage supplied to the 10 rows of 120 LEDs and the load current is shown according to the elapse of the test time, and is divided into four cases with air cooling and three cases with air cooling mist.
