Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes the natural flow of fluid to rotate an impeller completely, and uses the rotational force of the impeller to agitate a fluid that is the same as or different from the fluid. The present invention relates to a fluid agitation heat generating device that generates frictional heat and extracts the frictional heat as a heat source.

Fluid energy, such as river currents, ocean tides, and wind power, is an energy that nature contains infinitely.
The means to utilize these effectively are still at an underdeveloped stage. However, river water flow has traditionally been used as energy for power generation, and tidal power generation and wind power generation are also being put into practical use.

However, laws and regulations restrict such power generation from being supplied as general commercial power, although it may be used for personal households. Moreover, power generation using these natural forces has little practical effect unless all of the powerful energy is utilized, and the cost is inevitably high.

The present invention aims to effectively utilize natural fluid energy by converting it into thermal energy without generating electricity, and this fluid agitation heat generating device can be realized with a configuration using all simple means. Provide all.

An embodiment of the present invention will be described below with reference to all the drawings.

In FIG. 1, an impeller 2 is installed in a conduit 1 that serves as a fluid flow path.
is rotatably arranged. Reference numeral 3 denotes a support body for the impeller 2, which is fixed to the inner wall of the conduit 1 and supports the shaft portion 4'e of the impeller 2. The shaft portion 4 is directly connected to the stirrer 5, and the shaft 7 of the stirring blade 6 is directly connected to the impeller 2. The stirring blade 6 may be of either a centrifugal type or an axial type. The agitator 5 has a fluid suction port 8 to allow fluid to flow into the pipe line 1, and has a supply pipe line 90 as a heat extraction device 9 for extracting the fluid to the outside. The stirrer 5 is fixed to the inner wall of the conduit 1 with a support 3a. The supply pipe line 90 is connected to the load device 10 and is provided with a flow rate control valve 11 in the middle thereof. The flow rate control valve 11 adjusts the fluid flow rate with a needle valve or the like, and by adjusting the internal pressure of the agitator 5, the heat generation temperature of the fluid can be adjusted to either high or low.

Note that 12 is a discharge pipe line through which the fluid serving as a heat medium is supplied to the load device 10 and then discharged to the outside.

The operation of this embodiment device will be explained. When a fluid such as water is completely introduced into the conduit 1 from the front of the impeller 2, the impeller 2 rotates, and the rotation causes the stirring blade 6 to rotate. on the other hand,
A part of the fluid enters the inside of the stirrer through the suction port 8, and the fluid is stirred by the stirring blade 6, and the fluid generated by the stirring generates frictional heat and is heated. It is supplied to the load device 10 via a line 90. Therefore, in order to bring the total temperature supplied to the load device [10] to the desired value, the flow rate control valve 11 is operated, and if the flow rate becomes small, the pressure inside the stirrer 5 increases,
Frictional heat generation in the fluid is stimulated and the temperature rises. Conversely, if the flow rate is increased, the temperature will drop.

A second embodiment shown in FIG. 2 will be described. The device of this embodiment differs from the device of the first embodiment in that a heat exchanger 13 is used as the heat extraction device 9. That is, a heat exchanger 13 is interposed in a part of the supply pipe line 90, and all the heat medium exchanged by this heat exchanger 13 is loaded [
10 through a circulation line 14. The fluid after heat exchange is introduced into the pipe 1 through the discharge pipe 12 and reused.

A third embodiment shown in FIG. 3 will be described. The device of this embodiment differs from the devices of the first and second embodiments in that the stirrer 5 is sealed and has a circulation pipe 14 between it and the load device 10. A flow control valve 1 is provided in a part of the circulation pipe 14.
1 can be provided to adjust the temperature of the heat medium passing through the circulation pipe 14. Therefore, instead of stirring the fluid passing through the pipe line 1 to generate heat, it is possible to use a different type of heat medium, and is a modification of the heat extraction device.

The fourth embodiment shown in FIG. 4 will be fully explained. This embodiment device differs from the first to third embodiment devices in that a heat exchanger 13 is interposed between the stirrer 5 and the load device 10,
A heat extraction device 9 with a circulation pipe 14.degree. 14a interposed between these is provided.

In this way, if the heat exchanger 13 is used as shown in FIGS. 2 and 4, the heat medium between the heat exchanger 13 and the load device 10 may be an efficient fluid other than water (for example, fluorocarbon). Furthermore, by completely sealing the stirrer 5, any type of heat medium can be similarly selected between the stirrer 5 and the load device 10 or the heat exchanger 13.

Such a heat medium is not limited to liquid, but may be gas.

Note that the load device IO is a hot water user such as a domestic bath, a hot water source in various places, or an indoor heater. Further, the fluid introduced into the pipe 1 may be a natural flow of a river or tide, or an artificial water flow using a head difference, or may even introduce natural wind sound into the pipe 1.

In addition, in the case of the embodiments shown in FIGS. 8 and 4, the stirrer 5 does not necessarily need to be provided inside the pipe 1, but may be provided outside the pipe 1 via a bent shaft. There is no problem.

As described above, according to the present invention, fluid energy is easily converted into thermal energy with a simple and simple configuration, so it can greatly contribute to activities that utilize so-called small hydropower or small wind power, and can be used in small hydropower, etc. A device that easily obtains hot water or hot air and extracts thermal energy from nature for home or commercial use can be used to meet demand at a lower price than a power generation device, and since it is not a power generation device, it does not comply with the above regulations. Electricity, gas, oil,
It has an energy saving effect as a heating source in place of coal and other fuels.
