Description

Electricity generating device

[0001] The present disclosure relates to an electrical power generation device, and more particularly, to an electrical power generation device using a plasma-injected panel.

[0002] Unless otherwise indicated herein, the matters described in this identifier are not prior art to the claims of this application, and their description in this identifier is not intended to be deemed prior art.

[0003] Boilers provide the function of moving hot water through pipes to provide industrial hot water or to discharge hot water into heating pipes for indoor heating, but they have the disadvantage of large heat energy loss of hot water moving along the pipes.

[0004] Existing boiler-based power generation devices are being developed that provide a technology to generate electricity by attaching a thermoelectric element to a flue that increases in temperature, but an power generation device that utilizes the thermal energy of hot water has not been disclosed.

[0005] In this regard, Korean Patent Publication No. 10-1260609 discloses a thermoelectric generator installed in the flue of a household boiler, and Korean Patent Publication No. 10-2005413 discloses a thermoelectric generator for a boiler.

[0006] However, existing inventions do not disclose power generation technology using the thermal energy of hot water generated in a boiler.

[0007] The present invention provides an electric power generation device that generates electricity using hot water generated from a boiler.

[0008] In addition, it is obvious that the technical tasks are not limited to the technical tasks described above, and other technical tasks may be derived from the following description.

[0009] According to one embodiment of the disclosed content, the power generation device includes a boiler unit and an power generation unit connected to the boiler unit through a hot water pipe and a discharge pipe, and generating electricity by heating a first thermal junction of a first thermoelectric element through a panel heated by hot water flowing into the interior from the hot water pipe.

[0010] In addition, the power generation unit may include a tank connected to the hot water pipe so that the first space inside communicates with the internal space of the hot water pipe, a first panel having one end positioned to receive the hot water in the first space and the other end extending upward and coming into contact with the first hot junction at the outside of the tank, and a second panel coming into contact with the first cold junction formed on the first thermoelectric element at a position spaced apart from the first thermoelectric element.

[0011] In addition, the first and second panels are formed in the shape of a square plate that extends upward and downward and has a relatively large surface area that is in close contact with the first hot contact portion or the first cold contact portion, and a second space that is sealed and into which plasma ions are injected can be formed.

[0012] In addition, the power generation unit further includes a second thermoelectric element having a second cold junction in close contact with the second panel while being spaced apart from the first thermoelectric element with the second panel interposed therebetween, and the first panel, the first thermoelectric element, the second panel, and the second thermoelectric element may be repeatedly additionally arranged in the same order toward a single direction in proportion to the size of the tank.

[0013] Additionally, the power generation unit may further include a cooling unit coupled to the second panel to lower the temperature of the second panel.

[0014] According to one embodiment disclosed in this specification, the power generation device generates electricity by using the thermal energy of hot water generated from a boiler, and thus has the advantage of being able to generate electricity more stably and continuously than electricity generated from exhaust gas of the boiler.

[0015] In addition, the power generation device generates electricity by heating a thermoelectric element through a panel in which plasma ions are injected to improve thermal conductivity, so it has the advantage of allowing multiple thermoelectric elements to be attached to a panel with a relatively large area compared to a chimney, and improving the power generation efficiency.

[0016] In addition, since the effects of the present invention described as such are naturally exerted by the composition of the described contents regardless of whether the inventor is aware of them, the above-described effects are only a few effects according to the described contents and should not be recognized as describing all effects that the inventor has recognized or actually had. In addition, the effects of the present invention should be additionally recognized by the entire description of the specification, and even if not described in an explicit sentence, if a person with ordinary skill in the technical field to which the described contents belong can recognize such an effect through the specification, it should be regarded as an effect described in the specification.

[0085] The process of injecting plasma ions into the second space (2, 3) can be performed periodically according to the usage cycle of the power generation device (100), and through this, the performance of the power generation device (100) can be continuously maintained.

[0086] The inner surfaces of the first and second panels (430, 431, 432, 433, 434, 450, 451, 452, 453) exposed to the second space (2, 3) are coated with any one of neon, sulfuric acid, radon, or mercury, and the coating is performed after impurities remaining on the inner surfaces of the first and second panels (430, 431, 432, 433, 434, 450, 451, 452, 453) are removed.

[0087] The thermal conductivity of the first panel (430, 431, 432, 433, 434) itself is improved by plasma ions that fill the second space (2) of the first panel (430, 431, 432, 433, 434), and when the thermal energy of hot water is transferred from the first space (1), the temperature of the other end of the first panel (430, 431, 432, 433, 434) increases to be the same as the temperature of the hot water in a short period of time.
