Description of Embodiments

The best mode for carrying out the présent Invention will be described below with reference to Figs. 1 and 2.

ln a method for manufacturing high-density air according to the présent invention, as illustrated in Fig. 1, first, a desired amount of raw air A is supplied into a water-containing air generating means 1 having a sealed space via an air supply means 1a. Next, a large number of fine water particles W are injected to the supplied raw air A through a fine water particle supply means 1 b having a jet port such as a nozzle, and the raw air A is mixed with the fine water particles W.

As used ln the présent Invention, the raw air Aïs preferably air having normal temperature and pressure such as the atmosphère. However, the temperature and pressure of the raw air A can be freely selected and appropriately adjusted in accordance with the Implémentation of the 10 présent invention. Each of the fine water particles W Is as fine a water particle (small droplet) as possible in order to increase the surface area, and the particle diameter, temperature, and amount of supply of the fine water particles W are appropriately adjusted, for example, in accordance with the temperature, pressure, and amount of supply of the raw air A.

As described above, water-containing air A1 is generated by mixing the raw air A with the fine water particles W in the water-containing air generatïng means 1. Specifically, a large number of fine water particles W mixed in the raw air A are in gas-liquid contact with the raw air A and présent ln the raw air A while taking the heat of the raw air A. ln the présent invention, the air containing a large number of fine water particles W is referred to as the water-containing air A1.

In other words, the fine water particles W are present in the raw air A while holding the heat taken from the raw air A as latent heat of vaporization. Note that the present invention does not exciude a case where part of the fine water particles W In the water-containing air A1 Is vaporized into wet steam.

As described above, the température of the water-containing air A1 is lower than that of the raw air A, and accordingly the pressure of the water-containing air A1 is lower than that of the raw air A. As illustrated In Fig. 2, the volume of the water-containing air A1 is also smaller than that of the raw air A.

Specificaliy, assuming that the température, pressure, and volume of the raw air A are respectively denoted by T, P, and V (the same applies hereinafter), and the température, pressure, and volume of the water-containing air A1 are respectively denoted byT1, P1, and V1 (the same applies hereinafter), then the relations T > T1, P > P1, and V > V1 are satisfied with regard to the température, pressure, and volume, respectively.

Next, as illustrated in Fig. 1, the water-containing air A1 passes through a differential pressure suppiementing means 2 to be supplemented with a différence In pressure between the raw air A and the water-containing air A1, I.e., a differential pressure (P1 - P) between the pressure P of the raw air A and the pressure P1 of the water-containing air A1, whereby high-density air A2 is manufactured. Since the water-containing air A1 is pressurized to the original pressure P of the raw air A, the génération of heat can be suppressed to a great extent In this case, as compared with a case where the forcible compression is performed, that is, where the raw air A Is pressurized to a pressure higher than Its original pressure P. In this case, the suppression of heat génération is also achieved through the vaporization of the fine water particles W In the water-containing air

A1.

An already known blower machine such as a pressure fan, a fan, and a blower, or an already known known compressor is used as the differential pressure supplementing means 2 to supplément the water-containing air A1 with the differential pressure and transfer the high-density air A2 to a storage means 3 such as a tank. In particular, the blower machine can efficiently supplément the water-containing air A1 with the differential pressure and transfer the high-density air A2 when used as the differential pressure supplementing means 2.

The température and pressure of the manufactured high-density air A2 are higher than those of the water-containing air A1, promoting the vaporization of the fine water particles W. Accordingly, as illustrated in Fig. 2, the volume of the high-density air A2 is smaller than that of the water-containing air A1, whereas the pressure of the high-density air A2 is equal to that of the raw air A.

Specifically, assuming that the température, pressure, and volume of the high-density air A2 are respectively denoted by T2, P2, and V2 (the same applies hereinafter), then the relations T2 >

T1, P = P2 > P1, and V > V1 > V2 are satisfied with regard to the température, pressure, and volume, respectively. The température T of the raw air A Is equal to the température T2 of the high-density air A2, or one of the températures T and T2 is higher than the other, depending on the amount of contained fine water particles W, the amount of vaporized fine water particles W, and the like.

As described later, the high-density air A2 manufactured in the above-mentioned manner is supplied for utilization from the storage means 3 to an external combustion engins or an internai combustion engins serving as a heat engine 4.

Next, a method for utilizing high-density air according to the présent invention will be described.

First, a case where the high-density air A2 manufactured as described above is utilized as an operating gas for an external combustion engine serving as the heat engine 4 will be described. Examples of the extemal combustion engine Include a turbine having an extemal combustion structure such as an already known steam turbine, an already known free piston, an already known 15 rotary, and the like.

In this case, the high-density air A2 may be utilized as it is as the operating gas, but preferably it Is used together with steam S having a higher pressure than the high-density air A2.

Specifically, as illustrated in Fig. 1, In a case where the heat engine 4 is an extemal combustion engine, the high-density air A2 is suppiied to the extemal combustion engine 4 together with the steam S that is suppiied via a steam supply means 5.

The high-density air A2 and the steam S are simultaneously applied to the extemal combustion engine 4.

Altematively, the high-density air A2 and the steam S are applied to the extemal combustion engine 4 at a time Interval. More specifically, after the operation of the external combustion engine 4 is started by one of the high-density air A2 and the steam S, the other gas is suppiied to continue the operation of the extemal combustion engine 4. Consequently, it is possible to smoothly supply the subséquent gas (the other gas) at a relatively low supply pressure.

For example, when one gas is suppiied, the supply of the other gas is stopped, and when the other gas is suppiied, the supply of the one gas is stopped. Altematively, the supply end of one gas and the supply start of the other gas are synchronized with each other.

Since the high-density air A2 is a gas that does not condense at the condensation point of the steam S or gas that does not condense at the solidification point of the steam S, the high-density air A2 recovers the heat of condensation or heat of solidification released by the steam S, and inflates itself through the heat recovery to apply its gas pressure to the extemal combustion engine 4. Therefore, the high-density air A2 can effectively operate the extemal combustion engine 4 while appropriately receiving the thermal energy of the steam S.

Note that the présent invention does not exdude a case where the température, humidity, and pressure of the high-density air A2 are adjusted as necessary for the utilisation of the high-density air A2 as the operating gas for the extemal combustion engine 4.

Next, a case where the manufactured high-density air A2 is utilized as a combustion supporting gas for an internai combustion engine serving as the heat engine 4 will be described. Examples of the internai combustion engine include a turbine having an Internai combustion structure such as an already known gas steam turbine, an engine such as already known hydrogen, gasoline, and jet engines, and an already known boiler.

ln this case, the high-density air A2 is supplied to the internai combustion engine 4, compressed by a cylinder or the like of the internai combustion engine 4, and utilized to enhance the fuel combustion efficiency. The high-density air A2 densely contains a lot of oxygen to effectively improve the combustion efficiency. The high-density air A2 also contains a large number of fine water particles W together with steam, and the fine water particles W are also vaporized into steam and applied to the internai combustion engine.

Note that the présent invention does not exclude a case where the température, humidity, and pressure ofthe high-densityairA2 are adjusted as necessaryforthe utilization ofthe high-density air A2 as the combustion supporting gas for the internai combustion engine 4.

As described above, the method for manufacturing high-density air according to the présent invention includes mixing the raw air A with the fine water particles W to produce the water-containing air A1 instead of forcibly compressing the raw air A, and supplementing the water-containing airA1 with the differential pressure (P - P1) between the pressure P1 ofthe water-containing air A1 and the pressure P of the raw air A. Consequently, it is possible to efficientiy manufacture the high-density air A2 without unnecessariiy increasing the température and pressure and thus without causing energy loss such as the loss of thermal energy due to the increase and subséquent decrease in the température.

In addition, if the high-density air A2 manufactured with the above method is utilized as the operating gas for the extemal combustion engine together with the steam S having a higher pressure than the high-density air A2, the extemal combustion engine can be effectively operated.

Further, if the high-density air A2 manufactured with the above method is utilized as the combustion supporting gas for the internai combustion engine, the combustion efficiency in the internai combustion engine can be effectively improved.
