Device Which Applies Work To Outside With Environmental Thermal Energy

Abstract

The present invention relates to a device which applies work to the outside with environmental thermal energy, including a positive feedback heat pump system and a reciprocating multi-stage heat exchange working system. A high temperature heat source and a low temperature heat source are produced using a positive feedback heat pump, and at the same time the reciprocating multistage heat exchange working device applies work with heat energy and cold energy. As we can get several times of heat energy and cold energy when a certain amount of electric energy is consumed by a heat pump, and the thermal efficiency of the reciprocating multistage heat exchange working system is 100% theoretically, so we can get several times of electric energy. That is to say, its output is much bigger than its input, and the device can run without electric energy input, and provide electric energy to the outside.

DETAILED DESCRIPTION OF EMBODIMENTS

[0027] With reference to the attached picture, the embodiments s of the present invention are now described. Similar part designators in the attached picture represent similar components.

Embodiment 1

[0028] See FIG. 2. Its working process is as follows:

[0029] In the heat pump part, the Embodiment omits the energy recovery part, its working principle is shown in the part of the positive feedback heat pump.

[0030] Take some liquid with high expansion as the working medium, the pipeline (14), a Hydraulic cylinder(17), a Starter (15) and other accessories are interconnected. When the starter is heated (the starter can be placed in the container with the highest temperature, hot water can be added into the container with the highest temperature at the beginning), the working medium expands, so that the intensity of pressure inside the entire connector increases. Here, the Hydraulic cylinder (17) is connected into a differential mode, at first the Piston (18) moves to the right, at the same time, the Piston (18) moves the working medium to the right of the Piston (18) and in the pipeline passes through a multistage heat exchange device towards the left of the piston, the temperature of water in the leftmost multistage heat exchange container is the highest, the temperature of water in other containers reduces successively, the temperature of water in the rightmost container is the lowest. The working medium is heated during the process of moving. When the ratio of the diameter of Piston (18) and the diameter of piston rod is large enough, the volume increase of the moved working medium when it is heated is greater than or equal to the volume reduction caused by movement of the piston rod, the Piston (18) will keep moving, and the piston rod applies work to the outside through the Motion transfer mechanism (19), at the same time the return spring is compressed, the Motion transfer mechanism (19) drives the flywheel to rotate and applies work on Load A (20). Load A (20) can be an energy storage device or other loads. When the Piston (18) moves to the rightmost end, a crankshaft and a return spring push the Piston (18) to move in a reverse direction. At this time, the intensity of the pressure of working medium will rise to the highest level, the pressure limiting valve (16) is opened, and part of the working medium enters the Pressure limiting valve (16), so as to prevent excessive pressure of the working medium. When the Piston (18) moves in a reverse direction and the amount of the cooled working medium reaches a certain amount, the intensity of pressure in the system begins to decrease, and the working medium in the Pressure-limiting valve (16) is pressed back into the pipeline. As the Piston (18) continues to move, the intensity of pressure in the system further reduces and is lower than the atmospheric pressure, at the same time, under the action of the return spring, the Piston (18) moves to the left. When the Piston (18) moves liquid to the far left, under the action of inertia of the flywheel, the piston changes the direction again and moves toward the right. The process is repeated in this way. When the temperature of water in the multistage heat exchange container reduces to a certain level, a part of work applied by the device to the outside is used to start the heat pump compressor, and it stops after reaching a certain temperature.

[0031] We now take the liquid working medium with a high expansion coefficient as an example to describe the fundamental model. obviously it also can use some kind of gas as working medium.

Embodiment 2

[0032] The working process of the heat pump part is the same as embodiment 1.

[0033] In the drawing, the left end of the multistage heat exchange container has the highest temperature, and the right end has the lowest temperature. The working process is as follow, when the Liquid moving cylinder (22) rotates to a certain angle clockwise, under the action of gravity a Heavy piston (23) moves downward, at the same time, it presses the liquid working medium, and the liquid working medium passes through the multistage heat exchange device, and moves to the left of Liquid moving cylinder (22), when passing through the multistage heat exchange device, the working medium gradually heats up and expands, which results in increase of the volume in the whole connecting vessels, the piston of the Hydraulic cylinder (24) is pushed to apply work to the outside through the Motion transfer mechanism (25), compress the return spring at the same time, and drives the flywheel to rotate, applies work on Load B (26). When the Heavy piston (23) in the liquid moving cylinder declines to the lowest position, the Liquid moving cylinder (22) rotates to a certain angle anticlockwise, the position of Heavy piston (23) rises from the lowest position to the highest position, under the action of gravity, through the heat exchange device the liquid working medium is then moved in the reverse direction again, so that the working medium gradually cools and the volume reduces, and the return spring drives the piston of the Hydraulic cylinder (24) to apply work. When the Heavy piston (23) reaches the lowest position again, the Liquid moving cylinder (22) rotates to a certain angle in the reverse direction, so that the Heavy piston(23) drops and moves the liquid again. The process is repeated in this way. When the liquid expands, the intensity of pressure can be very high, and a Pressure limiting valve (21) is required to prevent excessive pressure in the whole connector, which may cause damage. When the temperature of water in the multistage heat exchange container falls to a certain level, part of the work applied by the device to the outside is used to start the heat pump compressor, and it will stop after reaching a certain temperature.

[0034] This method actually separates the piston and piston rod in Method 1. The swing type is suitable for the model of double cylinder system. it needs a large space, and is suitable for fixed occasions. The liquid moving cylinder can also be fixed, and the piston is moved by external force. For example, a magnet can be used. At this time, the piston can be a lightweight piston equipped with a magnet or an iron piston can be directly used. The cylinder needs to be made of non-ferromagnetic material, such as austenitic stainless steel. The heavy piston in the cylinder body can also be a light piston. By adding an oil pump in the pipeline, the liquid can be moved to and fro, which can make the structure more compact and not easily affected by position. With this method, the working medium also can be gas. Only the basic model is described here. On this basis, double cylinders, multiple cylinders and other technical proposals still fall under the scope for which protection is applied.

Embodiment 3

[0035] The working process of the heat pump part is the same as embodiment 1.

[0036] This method applies work with low-temperature steam, it is relatively suitable for power plants. In the drawing the temperature of water in the multistage heat exchange container is the highest on the left and lowest on the right. The working medium with a low boiling point is placed in a Liquid storage tank (30). At the start, the working Medium pump (29) is started and delivers the liquid working medium through a One-way valve (28) and a multistage heat exchange container to Steam Tank A (27). During the process, the working medium is gradually heated and gasified, and after it is heated in the container with the highest temperature the gaseous working medium it then goes through a Valve (34) and drives the Steam engine (33) (or turbine motor, etc.) to apply work on Load C (32). After working, the steam goes into Steam Tank B(31), and then passes through the containers for multistage cooling and liquidation, enters the Liquid storage tank (30), and is then delivered by a Medium pump (29) in a reverse direction to Steam tank A (27). The process is repeated in this way. When the temperature of water in the container falls to a certain level, part of the work applied by the device to the outside is used to start the heat pump compressor, and it will stop after reaching a certain temperature.

[0037] Described above are only preferred embodiments for the present invention. Of course, we cannot limit the scope of rights of the present invention with them. Therefore, the equivalent changes made in accordance with the scope of the patent applied for the invention are still within the scope covered by the present invention.
