Background Art

For engine, the traditional gasoline engine and diesel engine not only generate harmful gas, but about 50% fuels are transformed into engine overheating heat during the process of burning. When this kind of engines are applied to crankshaft, camshaft and valve, it is required higher technique and cause much higher costs as well as increasing of abrasion and weight, etc. Therefore, the power-source device of transforming steam heat into mechanical power is adopted to install in engine nowadays, in order to manufacture piston-style steam engine and steam turbine engine. For piston-style steam engine, it is already gradually eliminated because low efficiency of heat conversion and environment pollution; and the steam turbine engine is widely used in thermal power plants. Nevertheless, there is not the method and device of using the high-temperature and high-pressure vapor steam generated by saturated water explosion, and therefore it is necessary to study this field and design a new steam power device.

To enable those skilled in the art better understand the technical solution of the present invention, the following embodiments of the present invention will be further described in detail.

The present invention disclosed a steam power generating system, which includes saturated water generating device and saturated water explosive device. As shown in Fig. 1, the system includes inflow pipe 2, screw-plug 3, split-flow piece 4, obstruct-flow piece 5, thermal receptor 6, pillar 7, base 8, heat resource 10 and thermal conductor 11.

The said inflow pipe 2 is embedded into the said screw-plug, and the said screw-plug is connected with the sad thermal receptor 6 by the screw thread, and meanwhile generates preload pressure to the said split-flow piece 4 and the said obstruct-flow piece 5, and the other side of the said obstruct-flow piece 5 is connected with the said thermal conductor 11.

The said thermal conductor is embedded inside the said pillar 7, and also can adhere tightly outside the pillar 7 certainly.

The other side of the said pillar 7 is connected with the said base 8, and the said base 8 is connected with the shoulder on the inner wall of the said thermal receptor 6 so as to play support effect.

The outside of the said thermal receptor 6 is set with heat resource 10.

As shown in Fig. 2 and 3, the said split-flow piece 4 is set with several liquid-connecting groove 41, and the high-pressure liquid enters the liquid-connecting groove 41 through the inflow pipe 2.

The said obstruct-flow 5 is contacted with the said split-flow piece 4, and there are several outward convex 51 and concave 52 on the periphery of it.

The out edge of sad convex 51 props on the inner wall of the thermal receptor 6, and the liquid inside the liquid-connecting groove can enter the side of the pillar 7 through the concave 52.

The tiny channels are set between the said pillar 7 and the thermal receptor 6, and inside the tiny channels, the high-pressure water is heated to generate high-temperature saturated water.

The said tiny channel includes the gap 71 between the outer surface of the pillar 7 and the inner surface of the thermal receptor 6, and the width of the gap is less than 1mm.

Or the said tiny channel includes the several thin groove 72 on the outer surface of the pillar 7, and the width of the said thin groove is less than 1mm and the depth of it is less than 1mm.

Certainly, the said tiny channel can also includes the gap 71 and the thin groove 72 meantime, and it has been proved by many experiments over and over again that the effect of generating steam of the system is the best when the tiny channel includes the gap 71 and the thin groove 72 meantime along with the said gap 71 is less than 1mm.

The high-pressure liquid enters the inflow pipe 2 through the liquid pump 1, split by the split-flow piece 4, obstructed by the obstruct-flow piece 5, and then enters the said tiny channel and heated in the narrow space of the tiny channel to form high-temperature and high-pressure saturated water. After formed, the high-temperature and high-pressure saturated water is sprayed out from the tiny channel by high pressure and then forms tiny saturated water particles and hit the high-temperature stated saturated water explosive device and then occurs water explosion, quickly intensive evaporation and formation of high- temperature and high-pressure steam.

The said saturated water explosive device includes porous material body 9, and the porous material body is placed inside the cavity of the thermal receptor 6 and placed on the end close to the steam exit 13.

The porous material body 8 may be net structure.

The outer side of the said steam exit 13 is connected with power conversion device 14, and can be cylinder or steam turbine to work outwardly to generate power output.

The thermal conductor can be embedded into the pillar 7, and can also be outside of the pillar 7 independently, and is made of material with excellent high-temperature resistant and corrosion resistant. Since the end close to obstruct-flow piece 5 of the pillar 7 is contacted with high-pressure liquid first, the heat is absorbed quickly by the high-pressure liquid, leading to drop of its own temperature. So effect of setting of the thermal conductor 11 is to enhance heat conduction and enable heat of the pillar 7 can be supplemented quickly after the drop of the temperature and assure the steam dynamic generated by every pulse is smooth and steady. The base 8 along with the shoulder contact on the inner wall of the thermal receptor 6 plays support effect, and the porous material 9 is made of heat-resistant and anti-high-temperature-oxidative materials.

The present invention disclosed a method of generating steam power, which includes the steps as follows:

1. 1) making high-pressure liquid generate high-temperature saturated water;
2. 2) making the high-temperature saturated water explode instantly when heated, so as to form the high-temperature and high-pressure steam flow.

We all known the process of vaporization of water, for instance, putting 1kg, 0°C water into the container with piston, and heating the container from outside, and keeping the pressure inside the container is p invariantly. At the beginning, the temperature of the water is gradually increasing, and the volume is increased slightly. But after the temperature is rised to t_s corresponding to the saturated temperature of p and the water converted to saturated water, keep heating, then the saturated water changed gradually into saturated steam, es. so-called vaporization, until the ending of vaporization. During the whole process of vaporization, the temperature is kept at the saturated temperature t_s. During the process of vaporization, the specific volume usually increased a lot due to the increasing volume of the saturated water. Keeping heating, the temperature begins to increase again, and the specific volume is continuously increased, and the saturated steam is converted into overheating steam.

When water meets the high-temperature object, the explosion occurred. Due to the saturated water is in the high-temperature saturated state (critical pressure pc is 22.064MPa, critical temperature tc is 373.99 °C), with the stronger ability of vaporization compared with unsaturated water, less absorption of heat, faster vaporization, and can generate high-temperature and high-pressure steam flow when exploded instantly. And for steam, it only expanded when heated, not exploded when meeting with high-temperature objects.
