Technical Field

Background

Solar energy is clean energy and the amount of solar energy radiated to the earth every day is huge, so that the solar energy cannot be fully utilized by human beings at present, and the solar energy is particularly applied to households. The most common equipment at present is a solar water heater, and with the development of technology, some technical cases for directly applying solar energy in households appear, but some technical problems also exist.

Solar energy is applied in families, a heat-conducting medium is needed to transmit energy to the inside of a house, and the energy carried by the heat-conducting medium is different according to the temperature which can be reached by the heat-conducting medium. The conventional water is boiled at 100 ℃, and the heat conduction oil is cracked when reaching more than 350 ℃, so that the water cannot bear higher temperature. Limited by these conditions, the heat transfer medium does not reach very high temperatures, which means that the energy carried by the heat transfer medium is limited and cannot be broken through, so that the solar energy utilization rate is limited as a result.

Further, even if the heat transfer medium reaches a higher temperature, no pump is suitable for use. The technology is a common target when the technology is converted to civil use when the maintenance frequency is small because of strong durability.

This patent aims at proposing a new solution to the above-mentioned problems.

Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

The invention provides a multi-space interactive high-temperature tin heat conduction system which comprises a first container 1, a second container 2, a circulating conveying device 3, a heat collecting device 4, a heat storage device 5 and a heat supply device 6.

The first container 1 and the second container 2 are filled with metal tin. The first container 1 and the second container 2 are both communicated with liquid supply pipes, and the two liquid supply pipes respectively extend to the bottoms in the first container 1 and the second container 2. The two liquid supply pipes converge at one point outside the first container 1 and the second container 2, forming a liquid pipeline and leading into the heat collecting device 4. The heat collecting device 4 is a device that collects sunlight by using a lens and generates high temperature, and belongs to the prior art, and the details are not described herein. The specific principle is as follows: the medium in the pipeline can be directly heated by directly irradiating the focus of the light on the pipeline, and liquid tin is conveyed in the pipeline. The melting point of tin is 231.89 ℃ and the boiling point is 2260 ℃. Tin is easily heated and forms a liquid compared to other metals, while tin is non-toxic. Compared with other heat-conducting media, tin can reach higher temperature, can not be cracked like heat-conducting oil, and when heat collection device 4 uses Fresnel lens, can produce the temperature of at least 1000 ℃ at the light focus. The fact that higher temperature can be reached means that more energy can be carried, and the solar energy collection efficiency is improved. The liquid pipe is led out of the heat collecting device 4 and then led into the heat storage device 5. At the heat storage device 5, the liquid pipeline exchanges heat to release and store the heat into the magnesia brick, which is also the prior art and is not described herein again. After being led out from the heat storage device 5, the liquid pipeline is divided into two return pipes which are respectively communicated with the tops of the first container 1 and the second container 2.

In addition, check valves 7 are installed on both the supply and return pipes. The conveying direction of the one-way valve 7 on the liquid supply pipe is towards the heat collecting device 4; the direction of delivery of the non-return valve 7 on the return line is away from the heat storage means 5. The liquid metal tin circulation process is as follows: the metal tin in the first container 1 is conveyed into a liquid pipeline, heat absorption and temperature rise are carried out at a heat collecting device 4, heat release and temperature reduction are carried out at a heat storage device 5, and then the tin is conveyed into a second container 2. When all the tin in the first container 1 is transferred into the second container 2, the reverse transfer is performed. Tin is conveyed into the liquid pipeline from the second container 2, absorbs heat at the heat collecting device 4 to increase the temperature and releases heat at the heat storage device 5 to reduce the temperature, and then the tin is conveyed into the first container 1. At this point, the tin completes one cycle.

The first container, the second container, the liquid pipeline, the liquid supply pipe and the return pipe are all subjected to heat preservation treatment. It should be added that the feeding ports of the first container and the second container are arranged on the top, and the connecting structure of the cover for covering the feeding ports and the containers is sealed.

The heat supply device 6 is used for releasing heat to the first container 1 and the second container 2 to enable tin in the first container 1 and the second container 2 to be in a liquid state, and specifically comprises a hot oil pipeline and a hot oil pump, wherein the hot oil pipeline is filled with heat conduction oil. A part of the hot oil pipeline is arranged at the heat collecting device 4, the heat conduction oil is heated by obtaining the heat at the heat collecting device 4, but it is emphasized that the heat obtained by the hot oil pipeline is not directly irradiated on the heat conduction oil pipe by the light focus of the heat collecting device 4, and a heat radiation and/or heat conduction mode of a liquid pipeline can be utilized; a part of piping is additionally provided at the first container 1 and the second container 2 for discharging heat to the first container 1 and the second container 2, and an alternative structure such as a hot oil pipe is penetrated through the first container 1 and the second container 2 or wound on the outer walls of the first container 1 and the second container 2. The temperature of the heat conducting oil in the hot oil pipeline is required to be higher than the melting point of tin and lower than the self cracking temperature, so that the tin in the first container 1 and the second container 2 can be melted only by the heat released by the heat conducting oil.

The circulating conveyor 3 is used for providing power so as to convey the metallic tin in the first container 1 and the second container 2 away. The circulation delivery device 3 includes an air pump 31, a first valve 32, a second valve 33, a third valve 34, and a fourth valve 35. The outlet of the air pump 31 is connected to a first valve 32 and a second valve 33 through pipes, respectively. The other end of the first valve 32 is connected to a branch line, one branch of which is connected to the top of the first container 1, and the other branch of which is connected to one end of a third valve 34. The other end of the second valve 33 is likewise connected to a branching line, one branch of which is connected to the top of the second container 2 and the other branch is connected to one end of a fourth valve 35. The other ends of the third valve 34 and the fourth valve 35 are connected to an inlet of a cooling device 36 through a pipe, and an outlet of the cooling device 36 is connected to an inlet of the air pump 31 through a pipe. The cooling device 36 is used to cool the gas flowing through.

The working process of the circulating conveying device 3 is as follows: for example, when the amount of tin in the first container 1 is large and the amount of tin in the second container 2 is small, the tin in the first container 1 needs to be transferred to the second container 2. First, the first valve 32 and the third valve 34 are opened, and the second valve 33 and the fourth valve 35 are closed. After the air pump 31 works, high-pressure air enters the top of the first container 1, tin in liquid is pressed into the liquid pipeline under the action of air pressure, and the tin enters the second container 2 after passing through the heat collecting device 4 and the heat storage device 5. As the tin in the second container 2 increases, the pressure of the gas in the second container 2 increases, so that the gas in the second container 2 passes through the third valve 34 and then passes through the cooling device 36 to reach the air pump 31 to supply the air to the air pump 31. After the tin in the first container 1 is transferred, the first valve 32 and the third valve 34 are closed, and the second valve 33 and the fourth valve 35 are opened. After the air pump 31 works, high-pressure air enters the top of the second container 2, tin in liquid is pressed into the liquid pipeline under the action of air pressure, and the tin enters the first container 1 after passing through the heat collecting device 4 and the heat storage device 5. The pressure of the gas in the first container 1 increases with the increase of tin in the first container 1, so that the gas in the second container 2 reaches the gas pump 31 through the fourth valve 35 and the cooling device 36 to supply gas to the gas pump 31.

The design of circulation conveyor 3 has solved the problem that can't provide suitable pump transport high temperature tin, because utilize high-pressure gas to carry out the transport work of tin, whole circulation conveyor 3 need not direct contact high temperature tin, so can show improvement durability and reliability, do benefit to civilian implementation.

In addition, a temperature sensor and a liquid level sensor are also arranged in the first container 1; the heating device 6 is provided with temperature sensors at the first container 1 and the second container 2; the heat collecting device 4 is also provided with a temperature sensor for detecting the temperature of the liquid pipe. When the system starts to operate, a self-test of the system is first performed. The system firstly judges whether the temperature reaches the standard according to a temperature sensor in the heat collecting device 4, and if the temperature does not reach the standard, the system waits; and if the temperature reaches the standard, carrying out the next step. Then the system judges whether the temperature reaches the standard according to a temperature sensor in the heat supply device 6, and if the temperature does not reach the standard, the system waits; and if the temperature reaches the standard, carrying out the next step. Then the system judges whether the temperature reaches the standard according to the temperature sensors in the first container 1 and the second container 2, and if the temperature does not reach the standard, the system waits; and if the temperature reaches the standard, carrying out the next step. The system then determines which container has a high level based on the level sensors in the first and second containers 1, 2, and then operates the circulating conveyor 3 to move the tin to the other container, and the entire system begins to operate.
