Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an energy recycling system using a high-

The present invention relates to an energy recycling system for recycling the energy of a relatively high temperature hot water discharged indiscriminately from a power plant. More particularly, the present invention relates to an energy recycling system for recycling energy of a thermal power plant that can heat the heat energy of a hot water by using a heat pump, And to an energy recycling system using the same.

At present, power plants such as domestic thermal power plants and nuclear power plants use seawater as cooling water, and then send the heated seawater, that is, hot water, to the sea as it is.

In other words, due to the indiscriminate release of high-temperature, high-temperature water over an average annual temperature of 26.5 degrees, there is a problem of marine ecosystem disturbance such as destruction of seagrass habitat in the surrounding area due to surge of the ocean temperature,

I am being caused. In addition, only about 5,5 billion tons of hot water discharge is generated annually by domestic public corporations, which can not be recycled, resulting in an increase in energy production costs.

Accordingly, various technologies for recycling the above-mentioned hot water have been developed. Patent Application No. 10-2013-0074147 discloses a power plant that receives waste heat from a hot, high temperature water to generate electric power, 10-2010-0134983 discloses a technique for recovering waste heat and supplying it to a turbine for recycling to power generation.

As described above, various technologies for recycling waste heat have been developed. However, until now, it has been limited to the technology for recovering the waste heat from the hot water and using it as an energy source for operating a separate generator and the like. There are technical limitations in actual application.

Therefore, a heat storage container technology capable of transferring the heat source of the hot water of the power plant to a region requiring a heat source is required. Generally, the heat storage container is filled with a phase change material (PCM) Heat medium oil) is used to perform heat transfer between the outside and the container.

When the heat is stored in the container, hot heat oil heated by the external heat source is injected into the lower portion of the container to flow through the latent heat storage material, thereby transferring the heat amount of the heat oil to the latent heat storage material. The heat storage material dissolves while receiving heat in the solidified solidified state, and becomes a liquid state.

As the latent heat storage material is changed from solid to liquid, the latent heat storage material is coagulated from the liquid to the solid in the heat dissipation process later, and the heat oil is heated, and the heat oil is heated from the heat storage container to the outside .

In order to achieve effective heat exchange in as short a time as possible in the heat transfer process between the thermal oil and the latent heat storage material, it is necessary that the thermal oil flow uniformly through the latent heat storage material as wide as possible.

However, in the conventional heat storage container, when the high-temperature heat oil flows through the coagulated latent heat storage material in the heat storage process, the drift is first generated first and then the heat is transferred between the heat oil and the latent heat storage material due to the uneven flow phenomenon There is a problem that the heat storage and heat dissipation time becomes longer.

As one type of this type of heat storage container, Deutsches Zentrum für Luft-und Raumfahrt has developed a system for storing latent heat using a heat transfer medium. This system uses the principle that the latent heat is stored in the heat storage system by circulating the heat transfer medium through a vessel, and there is a difficulty in manufacturing process to install a plurality of pipes (EP 789214).
