Abstract
본 발명은 태양열과 중력을 이용한 동력생산(Power Generation) 방법에 관한 것이다. 태양열을 이용한 발전 방법으로서 태양광으로부터 직접 전력을 얻는 태양전지(Solar Cell)에 의한 방법을 들 수 있다. 또 하나의 동력생산 방법으로서, 태양광을 반사경으로 모아 수증기를 고온으로 가열하고, 이 고온의 증기로 터빈을 돌려 발전하는 방법을 들 수 있다. 터빈을 이용한 동력생산 방법에서는, 수증기를 고압에서 고온으로 가열해야 하고, 이 고온고압의 수증기를 고속의 스팀 Jet으로 변환하여 터빈의 날개(Blade)에 충돌시킴에 따라 터빈 로우터가 회전하게 됨으로 장치가 복잡하고, 열효율이 낮은 결함이 있었다. The present invention relates to a power generation method using solar heat and gravity. As a power generation method using solar heat, there is a method using a solar cell that directly obtains power from sunlight. As another power production method, there is a method of collecting solar light with a reflector, heating water vapor at a high temperature, and rotating the turbine with this high temperature steam to generate electricity. In a power generation method using a turbine, the steam generator must be heated from high pressure to high temperature, and the turbine rotor rotates as the high temperature and high pressure steam is converted into a high speed steam jet and collides with the blade of the turbine. There was a complex, low thermal efficiency defect.
본 발명은 이러한 결함을 해소하기 위하여, 상업용으로 이미 생산되고 있는 기기들 또는 공지의 기술로 제작될 수 있는 것들로 다음과 같이 구성된 것이다.The present invention is configured as follows to solve such defects, the devices that are already produced commercially, or those that can be produced by known techniques.
본 발명에서는 작업유체로서 분자량이 크고 휘발성이 큰 물질이 사용된다. 여기에서는 작업유체를 n-Butyl Alcohol(이하 알코올이라 칭함)로 가정한다. 알코올은 태양광으로 보일러(1)에서 상온보다 조금 더 높은 60℃ 이상의 온도로 가열된다. 이 보일러의 압력은 알코올이 충분히 증발할 수 있을 정도로 낮다. 알코올은 보일러에서 과열증기로 변하여 위로 상승한다.In the present invention, a high molecular weight and high volatility material is used as the working fluid. It is assumed here that the working fluid is n-Butyl Alcohol (hereinafter referred to as alcohol). The alcohol is heated by sunlight to a temperature of 60 ° C. or more in boiler 1 which is slightly higher than room temperature. The pressure in this boiler is low enough for the alcohol to evaporate sufficiently. The alcohol turns into superheated steam in the boiler and rises up.
본 발명에서는 매우 높은 (250m로 가정) 곳에 에어핀 쿨러 형태의 복수기(3)가 설치된다. 작업유체는 보일러(1)에서 압력조절용 송풍기(2)를 경유하여 상기 복수기로 유입된다. 알코올의 온도가 상기 보일러 출구에서 75℃ 정도일 경우, 위로 약 250m 상승할 때, 중력의 영향으로 온도가 60℃ 정도로 낮아진다. 이러한 알코올 증기는 상기 복수기(3)에서 상온으로 냉각되면서 응축되어 액체로 변한다. 따라서 응축된 알코올은 지상에 설치되어 있는 수차(4)와의 높이차(h)에 해당하는 위치에너지(mgh)를 갖게 된다.In the present invention, the air condenser 3 in the form of an air fin cooler is installed at a very high position (assuming 250 m). The working fluid is introduced into the condenser via the pressure control blower 2 in the boiler 1. When the temperature of the alcohol is about 75 ° C. at the boiler outlet, when it rises about 250 m upwards, the temperature decreases to about 60 ° C. under the influence of gravity. This alcohol vapor is condensed and cooled into a liquid while being cooled to room temperature in the condenser 3. Therefore, the condensed alcohol has a potential energy (mgh) corresponding to the height difference (h) with the aberration (4) installed on the ground.
이러한 작업유체(알코올)는 아래로 내려오면서 그 위치에너지로 지상에 위치한 (밀폐공간으로 작동하는) 수차(4)를 구동시키고, 이 수차에는 발전기(5)가 연결되어 있어 유용한 전력이 생산된다. 작업유체는 수차(4)에서 앞서 기술한 보일러(1)에 유입되고, 다시 가열되어 앞서 기술한 과정이 반복된다. 이와 같이 본 발명에서는 중력을 이용하여 저온에서도 유용한 전력을 생산할 수 있도록 구성한 것이 특징이다.This working fluid (alcohol) is driven down to drive aberrations 4 (operating in an enclosed space) on the ground with its potential energy, which is connected to a generator 5 to produce useful power. The working fluid enters the boiler 1 described above in the aberration 4, is heated again, and the above-described process is repeated. As described above, the present invention is characterized by being configured to produce useful power even at low temperatures by using gravity.
Description
본 발명은 태양열과 중력을 이용한 동력생산(Power Generation) 방법에 관한 것이다. 태양열을 이용한 발전 방법으로서 태양광으로부터 직접 전력을 얻는 태양전지(Solar Cell)에 의한 방법과 태양광을 반사경으로 모아 수증기를 고온으로 가열하고, 이 고온의 증기로 터빈을 돌려 동력을 생산하는 방법을 들 수 있다. 터빈을 이용한 동력생산 방법에서는, 수증기를 고압에서 고온으로 가열해야 하고, 이 고온고압의 수증기를 고속의 스팀 Jet으로 변환하여 터빈의 날개(Blade)에 충돌시킴에 따라 터빈 로우터가 회전하게 됨으로 장치가 복잡하고 열효율이 낮은 결함이 있었다.The present invention relates to a power generation method using solar heat and gravity. As a power generation method using solar heat, a method using a solar cell that obtains electric power directly from sunlight, a method of collecting solar light with a reflector, heating water vapor at a high temperature, and rotating a turbine with this high temperature steam to produce power. Can be mentioned. In a power generation method using a turbine, the steam generator must be heated from high pressure to high temperature, and the turbine rotor rotates as the high temperature and high pressure steam is converted into a high speed steam jet and collides with the blade of the turbine. There was a complex and low thermal efficiency defect.
본 발명은 이러한 결함을 해소하기 위하여 안출한 동력생산 방법이다. 본 발명의 목적은 시스템을 (상온보다 조금 더 높은) 저온에서 작동하도록 구성하여 그 열원으로 태양열, 지열, 또는 버려지는 기타 열에너지를 이용하여 동력을 생산하는 방법을 제공코자 함에 있다. 본 발명은 공지의 기술인 (밀폐공간으로 작동하는) 로터리 수차(Water Turbine)와 이미 상업용으로 생산되고 있는 보일러 및 복수기(Condenser) 등으로 다음과 같이 구성된다.The present invention is a power production method devised to solve such a defect. It is an object of the present invention to provide a method of producing power using solar, geothermal, or other thermal energy that is discarded as its heat source by configuring the system to operate at low temperatures (a little higher than room temperature). The present invention comprises a known water turbine (operating in an enclosed space) and a boiler and condenser already commercially produced as follows.
동력을 발생하는 로터리 수차와 태양광에 의한 보일러는 지상에 설치되고, 압력 조절용 송풍기와 에어핀 쿨러 형태의 복수기는 지상으로부터 매우 높은 위치에 설치되며, 이들은 작업유체가 순환하도록 배관 및 닥트(Duct)로 연결된다. 여기에서는 상기 복수기가 250m의 높이에 있다고 가정하자. 본 발명에 사용된 수차는 밀폐공간에서 작업유체를 연속적으로 압송할 수도 있고 또 수차로도 사용할 수 있는 '로터리 유체 이송 장치'(특허 등록번호 20-2002-0003934)가 적합하다.Power-generating rotary aberrations and solar boilers are installed on the ground, and pressure-controlled blowers and air fin coolers are installed at a very high position from the ground. Leads to. Assume here that the condenser is at a height of 250 m. The aberration used in the present invention is suitable for the 'rotary fluid transfer device' (patent registration number 20-2002-0003934) which can continuously press the working fluid in a closed space and can also be used as an aberration.
밀폐공간의 체적변화로 작동하는 대표적인 펌프는 크랭크-피스톤으로 구성된 피스톤 펌프이다. 이 펌프는 효율이 매우 좋으나 그 구조상 작업유체의 흐름이 연속적으로 이루어지지 않기 때문에 동력을 발생시키는 수차로는 활용할 수 없다. 그러나 앞서 소개한 '로터리 이송 장치'는 피스톤 펌프처럼 밀폐공간의 체적변화로 유체를 압송하면서 유체의 흐름이 원심펌프에서와 같이 연속적으로 이루어진다. 따라서 이 장치는 그 출구에 압력을 지닌 유체를 입력하면 역으로 동력이 발생함으로 수차로 사용할 수 있고, 그 효율을 (물을 날개에 충돌시키는 형태의) 기존 상업용 수차보다 더 높일 수 있다.A representative pump that operates with a volume change of the enclosed space is a piston pump composed of a crank piston. This pump is very efficient, but because of its structure, the working fluid does not flow continuously, so it cannot be used as a power generating aberration. However, the 'rotary transfer device' introduced above, like the piston pump, pressurizes the fluid by changing the volume of the closed space, and the flow of the fluid is continuously performed as in the centrifugal pump. Thus, the device can be used as aberrations by inputting a fluid with pressure at its outlet, which in turn generates power, increasing its efficiency more than conventional commercial aberrations (in the form of colliding water with the wing).
본 발명에 사용되는 작업유체는 증발열(잠열)이 작고, 휘발성이 크고, 분자량이 큰 물질이어야 한다. 본 발명의 작업유체가 n-Butyl Alcohol(이하 알코올이라 칭함)이라고 가정하자. 본 발명에서 작업유체인 알코올은 보일러에서 75℃ 정도의 온도로 가열된다. 가열 온도가 낮음으로 열원으로서 태양열, 지열 또는 기타 버려지는 열에너지를 사용할 수 있다. 보일러의 압력이 59 mmHg 정도로 유지된다고 보면, 알코올 증기는 75℃에서 과열상태 (Industrial Solvents Handbook Table 6.74 참고, 5th Edition 1998) 이다.The working fluid used in the present invention should be a material having low evaporation heat (latent heat), high volatility, and high molecular weight. Assume that the working fluid of the present invention is n-Butyl Alcohol (hereinafter referred to as alcohol). Alcohol working fluid in the present invention is heated to a temperature of about 75 ℃ in the boiler. The low heating temperature allows the use of solar, geothermal or other waste heat energy as the heat source. Given that the pressure in the boiler is maintained at 59 mmHg, the alcohol vapor is superheated at 75 ° C (see Industrial Solvents Handbook Table 6.74, 5th Edition 1998).
이 과열증기는 위로 상승하여 복수기로 유입되는데, 만약 보일러에서 복수기로 연결된 관에서 증기가 연속적으로 흐르지 않을 경우, 관내에서 대류가 일어나 상층부의 온도가 더 높아야 한다. 그러나 보일러에서 증발된 증기가 관을 따라 연속적인 흐름(Steady Flow)으로 상승하여 약 250m(가정)의 높이에 위치한 복수기로 유입될 경우, (보일러 출구에서 75℃인) n-Butyl 알코올 증기는 복수기 입구에서 (포화상태인) 60℃ 정도로 그 온도가 강하된다. 이는 기체일지라도 중력의 영향을 받게 됨으로 위로 올라가면서 그 운동속도가 감속되기 때문이다. 바꾸어 말하면 속도에너지가 위치에너지(mgh)로 바뀐 것이다. 다음은 그 온도가 15℃ 강하되는 것을, 알코올 증기가 과열증기임으로 이상기체로 가정하고, 계산한 근거이다.The superheated steam rises upwards and enters the condenser. If there is no continuous flow of steam in the conduit connected to the condenser, convection occurs in the conduit and the temperature of the upper layer must be higher. However, if the vapor evaporated from the boiler rises into a continuous flow along the pipe and enters the condenser located at a height of about 250 m (home), the n-Butyl alcohol vapor (at 75 ° C. at the boiler outlet) is condensed. The temperature drops to about 60 ° C (saturated) at the inlet. This is because even the gas is subject to gravity, and its speed of movement slows down. In other words, the velocity energy is converted into potential energy (mgh). The following is a calculation based on the assumption that the temperature drops by 15 ° C and assumes an ideal gas because alcohol vapor is a superheated vapor.
물질의 온도는 입자 평균 운동속도의 척도로서 열역학에서 Eaver = 3/2 k T, 즉 T = 1/3 1/k mv2 rms 로 정의된다. 여기에서 k 는 볼츠만 상수(1.3805x10-23 J/°K)이고, T는 절대온도(°K), m은 입자의 질량(kg), vrms은 입자의 제곱평균속도(m/s, Root-Mean-Square = 1/N ∑v2) 이다. 같은 분자로 구성된 계(System)라 할지라도 모든 입자가 같은 속도로 운동하지는 않는다. 더 빨리 운동하는 입자도 있고 또 매우 느리게 운동하는 입자도 있다. 그러나 이들의 평균속도(rms)는 위의 공식을 만족한다. 따라서 분자량 74인 (1/(6.022x1023)x74/1000kg) CH3CH2CH2CH2OH 알코올 분자가 온도 75°C(348°K)일 때 평균 운동속도는 vaver = (k T 3/m)1/2 = (1.3805 x 348 x 3 x 6.022/74 x 1000)1/2 = 342.5 m/s로 계산된다. 따라서 이 분자가 250m 상승했을 경우 위치에너지가 증가한 량만큼 그 운동에너지가 감소해야 함으로 (1/2mv1 2 = mgh + 1/2mv2 2), 결국 그 온도가 약 15℃ 정도 낮아진다.The temperature of a substance is defined as E aver = 3/2 k T, ie T = 1/3 1 / k mv 2 rms , in thermodynamics as a measure of the average particle velocity. Where k is the Boltzmann constant (1.3805x10 -23 J / ° K), T is the absolute temperature (° K), m is the mass of the particle (kg), v rms is the mean square velocity of the particle (m / s, Root -Mean-Square = 1 / N ∑v 2 ). Even with a system of identical molecules, not all particles move at the same speed. Some particles move faster and some move very slowly. However, their average speed (rms) satisfies the above formula. Thus, when the molecular weight of 74 (1 / (6.022x10 23 ) x74 / 1000kg) CH 3 CH 2 CH 2 CH 2 OH alcohol molecule is 75 ° C (348 ° K), the average kinetics is v aver = (k T 3 / m) 1/2 = (1.3805 x 348 x 3 x 6.022 / 74 x 1000) 1/2 = 342.5 m / s. Therefore, if the molecule rises by 250m, the kinetic energy must be reduced by the amount of potential energy increase (1 / 2mv 1 2 = mgh + 1 / 2mv 2 2 ), and thus the temperature is lowered by about 15 ° C.
상승하면서 온도가 낮아져 포화상태로 된 알코올 증기는 복수기에 유입되고 상온으로 냉각되면서 응축된다. 이 응축에 따라 (증기가 응축되면 그 체적이 급속히 줄어들게 됨으로) 마치 화력발전소에서 LP 터빈을 빠져나온 스팀이 복수기에서 응축되면서 부피가 줄어들고 그 결과로 터빈의 스팀이 빠른 속도로 복수기로 끌려가듯이, (지상에 있는) 보일러에서 이 복수기로 흐르는 작업유체(증기)는 빠른 속도로 복수기로 흡입되고, 복수기에서 액체로 변한 작업유체는 복수기의 높이에 해당하는 위치에너지(mgh)를 갖게 된다.As the temperature rises, the saturated alcohol vapor flows into the condenser and condenses as it cools to room temperature. This condensation (as vapor condenses rapidly decreases in volume) as if the steam exiting the LP turbine from a thermal power plant condensed in the condenser, reducing its volume and consequently leading the turbine's steam to the condenser at high speed. The working fluid (steam) flowing from the boiler (on the ground) to this condenser is sucked into the condenser at high speed, and the working fluid which has changed from the condenser to liquid has a potential energy (mgh) corresponding to the height of the condenser.
이러한 위치에너지(mgh)를 지닌 작업유체는 내려오면서 지상에 설치된 로터리 수차를 구동시키고, 이어 다시 보일러로 유입되어 가열되고 앞서 기술한 과정이 반복된다. 따라서 수차에 연결되어 있는 발전기에서 유용한 전력이 생산되는 바, 시스템에서 발생한 기계적 마찰손실 및 유체 이동에 따른 마찰손실을 뺀 나머지 동력은 출력된다.The working fluid with this potential energy (mgh) drives the rotary aberrations installed on the ground as it descends, then flows back into the boiler and is heated and the process described above is repeated. Therefore, useful power is produced by the generator connected to the aberration, and the remaining power is subtracted from the mechanical frictional loss generated by the system and the frictional loss caused by fluid movement.
이와 같이 본 발명은 그 규모는 매우 클 것으로 예상되나, 간단한 장치로 어떠한 공해도 없이 동력을 생산하도록 구성한 것이 특징이다. 본 발명에서는 복수기의 위치가 높으면 높을수록, 또 작업유체의 분자량이 크면 클수록 그 열효율이 높아진다. 본 발명에 적합한 작업유체의 개발에 대하여 앞으로 Chemical Engineer의 연구가 기대된다.Thus, the present invention is expected to be very large in size, but is characterized by being configured to produce power without any pollution by a simple device. In the present invention, the higher the position of the condenser and the larger the molecular weight of the working fluid, the higher the thermal efficiency. Chemical engineers are expected to study the development of working fluids suitable for the present invention.
도 1은 자연 상태에서, 지상의 물분자가 태양열로 에너지를 얻어 증기로 되고, 공중을 비행하여 높이 올라, 구름의 물방울로 되는 것을 상징적으로 보인 것이다. 물론, 물분자가 위로 상승하면서 도 1에 보인 바와 같이, 마치 돌멩이처럼 운동하지는 않는다. 물 입자는 매우 빠른 속도로 무질서한 브라운(Brown) 운동을 한다. 그러나 위로 상승하는 평균 속도는, 돌멩이가 중력의 영향을 받아 그 속도가 감속되듯이, 감속된다.FIG. 1 is a symbolic view of water molecules on the ground, which are energized by solar heat, become vapors, fly high in the air, and become cloud droplets. Of course, as the water molecules rise up, as shown in Fig. 1, they do not move like stones. The water particles make a disorderly brown movement at very high speeds. But the average speed that rises is slowed down, just as the stone slows down under the influence of gravity.
높이 오른 물분자는 그 속도가 느려지고, 대신에 높이(h)에 해당하는 위치에너지(mgh)를 얻게 된다. 본 발명은 이러한 원리를 이용하여 분자량이 크고, 끓는점이 낮고, 증발열(잠열)이 적은 작업유체를 이용하여 비교적 낮은 온도에서 동력을 생산하도록 다음과 같이 구성한 동력생산 방법에 관한 것이다.Higher water molecules are slowed in speed, and instead have potential energy (mgh) corresponding to height (h). The present invention relates to a power production method configured as follows to produce power at a relatively low temperature using a working fluid having a large molecular weight, a low boiling point, and a low heat of evaporation (latent heat) using this principle.
본 발명에 사용된 작업유체는 n-Butyl Alcohol(이하 알코올이라 칭함)로 가정한다. 본 발명은 도 2에 보인 바와 같이 지상에 (밀폐공간으로 작동하는) 로터리 수차(4)가 설치되어 있고, 여기에 배관으로 연결되어 있는 보일러(1)가 설치되어 있으며, 지상으로부터 매우 높은 위치에 보일러의 압력 조절용 송풍기(2) 및 에어핀 쿨러 형태의 복수기(3)가 설치되어 있다. 상기 보일러(1), 송풍기(2) 및 복수기(3)는 서로 닥트(Duct)로 연결된다. 이들의 높이가 250m라고 가정하자.The working fluid used in the present invention is assumed to be n-Butyl Alcohol (hereinafter referred to as alcohol). In the present invention, as shown in Fig. 2, a rotary aberration 4 (operating in an enclosed space) is installed on the ground, and a boiler 1 connected to the pipe is installed, and is located at a very high position from the ground. The pressure control blower 2 of the boiler and the condenser 3 in the form of an air fin cooler are provided. The boiler 1, the blower 2 and the condenser 3 are connected to each other by a duct. Suppose their height is 250m.
이와 같이 구성된 본 발명에서는, 보일러(1)에서 태양열로 작업유체(알코올)가 온도 75℃ 정도로 가열된다. 보일러의 압력은 보일러로 유입되는 유체의 흐름(Flow Rate)과 위에 설치되어 있는 압력조절용 송풍기(2)에 의하여 59 mmHg 정도로 유지될 수 있다. 보일러에서 과열증기로 가열된 알코올 증기는 위로 상승하고, 250m를 상승하면 중력의 영향으로 그 온도가 약 60℃ 정도로 강하된다. 즉, 증기의 속도에너지가 위치에너지로 변한 것이다.In the present invention configured as described above, the working fluid (alcohol) is heated to about 75 ° C. by solar heat in the boiler 1. The pressure of the boiler may be maintained at about 59 mmHg by the flow rate of the fluid flowing into the boiler and the pressure regulating blower 2 installed thereon. The alcohol vapor heated by the superheated steam in the boiler rises upward, and when it rises 250m, the temperature drops to about 60 ° C under the influence of gravity. In other words, the velocity energy of the steam is changed to potential energy.
온도가 15℃ 낮아져 포화상태로 된 알코올 증기는 복수기(3)에 유입되고, 냉각되면서 응축된다. 결과로 (증기의 체적이 급격히 줄어듦에 따라) 보일러의 알코올 증기는 더욱 빠른 속도로 상승하여 복수기로 흡입되고, 응축된 알코올은 복수기에 해당하는 위치에너지(mgh)를 갖게 된다. 위치에너지를 지닌 작업유체는 내려오면서 (밀폐공간으로 작동하는) 로터리 수차(4)를 구동시키고, 이어 보일러(1)로 유입되어 다시 가열되고, 앞서 기술한 과정이 반복된다.The temperature is lowered 15 ° C saturated alcohol vapor flows into the condenser (3), it is condensed while cooling. As a result, the alcohol vapor in the boiler rises faster and is sucked into the condenser (as the volume of steam sharply decreases), and the condensed alcohol has a potential energy (mgh) corresponding to the condenser. As the working fluid with potential energy descends, it drives the rotary aberration 4 (which acts as an enclosed space), then enters the boiler 1 and is heated again, and the above-described process is repeated.
결과로서 수차에 연결되어 있는 발전기(5)에서 유용한 전력이 생산되는 바, 시스템에서 발생한 기계적 마찰손실 및 유체 이동에 따른 마찰손실을 뺀 나머지 동력은 출력된다. 즉, 자연 상태에서 수증기가 태양열로 높이 올라 위치에너지를 갖게 되듯이, 보일러에 가해진 태양열 에너지가 작업유체를 들어올림에 따라 유용한 동력으로 변환된 것이다.As a result, useful power is produced in the generator 5, which is connected to the aberration, and the remaining power is subtracted from the mechanical frictional loss generated in the system and the frictional loss due to fluid movement. In other words, just as water vapor rises to the solar heat in the natural state and has potential energy, the solar energy applied to the boiler is converted into useful power by lifting the working fluid.
본 발명은 저온으로 어떠한 공해도 없이 동력을 생산하도록 안출한 동력생산 방법으로서 에너지원이 부족한 국가에 크게 기여할 수 있는 것이다. The present invention is a power production method designed to produce power without any pollution at low temperature can greatly contribute to a country lacking an energy source.
