Description

수산 가스 발생 장치{Apparatus for generating a hydrogen gas and oxygen gas}Apparatus for generating a hydrogen gas and oxygen gas}

Field of the Invention The present invention relates to a hydroxyl gas generating apparatus, and has a function of removing foreign matters through a circulation of an electrolyte solution and a cooling function, and also relates to a hydroxyl gas generating device that separates moisture from generated hydroxyl gas and can be used as a new electrolyte.

수산 가스 발생 장치에서 발생되는 문제점들 중의 하나는 전기 분해가 이루어지는 전해액의 과열 현상이다. 전해조 내에는 전해액을 전기 분해시키는 전극이 위치하게 되며, 이 전극에는 일반적으로 3상(3-phase)의 220 볼트 또는 380 볼트의 전원이 공급된다. 장시간의 전기 분해 공정이 진행됨에 따라 전해액은 가열되며, 전해액의 온도가 높아질수록 전해액의 전기 분해 효율은 낮아지게 된다. 따라서 가장 우수한 전기 분해 효율을 얻을 수 있는 전해액의 최적 온도(50 내지 60℃)를 유지하는 것이 바람직하다.One of the problems occurring in the oxy-gas generator is the overheating of the electrolytic solution. Within the electrolyzer is an electrode that electrolyzes the electrolyte, which is typically supplied with a three-phase 220 volt or 380 volt power.

이상과 같은 구성을 갖는 본 발명의 작동 과정을 설명하면 다음과 같으며, 편의상 액체(물 또는 전해액)가 흐르는 라인은 점선으로, (수산화 칼륨을 포함한) 수산 가스가 흐르는 라인은 실선으로 도시하였다.Referring to the operation of the present invention having the configuration as described above is as follows, for convenience, the line through which the liquid (water or electrolyte) flows is shown by the dotted line, the line through which the hydroxide gas (including potassium hydroxide) flows is shown by the solid line.

전해액이 담겨진 각 전해조들(10 및 20) 내에 장착된 전극에 전원이 인가되면, 전해액에 대한 전기 분해가 진행된다. 전기 분해의 결과로서 수산 가스가 발생되며, 이 수산 가스는 전해조들(10 및 20)과 전해액 공급 탱크(30)를 연결하는 라인을 따라 전해액 공급 탱크(30) 내부 공간으로 유입된다. 전해질인 KOH가 함유된 수증기 상태의 수산 가스가 전해액 공급 탱크(30) 내의 물과 접촉하게 되면 수용성인 KOH는 용해되며, 이후, 수분이 함유된 수산 가스는 전해액 공급 탱크(30)와 기액 분리기(40)를 연결하는 라인을 통하여 기액 분리기(40)로 유입된다.When power is applied to the electrodes mounted in the respective electrolytic baths 10 and 20 in which the electrolyte is contained, electrolysis of the electrolyte proceeds. As a result of the electrolysis, hydroxyl gas is generated, which is introduced into the space of the electrolyte supply tank 30 along a line connecting the electrolytic baths 10 and 20 and the electrolyte supply tank 30. When the water vapor in the state of steam containing the KOH electrolyte is in contact with the water in the electrolyte supply tank 30, the water-soluble KOH is dissolved, and the water-containing hydroxide gas is then supplied to the electrolyte supply tank 30 and the gas-liquid separator ( It is introduced into the gas-liquid separator 40 through a line connecting the 40.

기액 분리기(40) 내에서 습기가 분리(기액 분리기의 상세 구성은 본 출원과 동일자로 출원되는 발명의 명칭이 "기액 분리기"(원서번호 1)에 상세하게 설명됨)되며, 순수한 가스는 배출부(43)를 통하여 외부 설비로 배출되며, 수집된 수분은 기액 분리기(40) 하부 공간에서 응집된다. 한편, 기액 분리기(40) 하부 공간에는 이러한 과정을 통하여 형성된 물이 저장되어 있다.Moisture is separated in the gas-liquid separator 40 (the detailed configuration of the gas-liquid separator is described in detail in the name "gas-liquid separator" (Application No. 1) filed with the same person as the present application), and the pure gas is discharged. Discharged to an external facility through 43, the collected water is aggregated in the space below the gas-liquid separator (40). On the other hand, the water formed through this process is stored in the lower space of the gas-liquid separator 40.

전해조들(10 및 20) 내부의 전해액(전기 분해 과정에서 가열된 상태임)은 제 1 전해액 순환 라인(L1)을 통하여 필터(50) 내부로 유입되며, 전해액이 이 필터 (50)를 통과하는 과정에서 전해액에 함유되어 있던 불순물들은 제거된다. 이후 이물질이 제거된 전해액은 냉각 수단(70) 내부로 유입된다. 여기서, 전해액의 순환은 냉각 수단(70)과 필터(50) 사이의 라인에 설치된 펌프(60)에 의하여 이루어짐은 물론이다.The electrolyte solution (heated during the electrolysis process) inside the electrolytic baths 10 and 20 flows into the filter 50 through the first electrolyte circulation line L1, and the electrolyte solution passes through the filter 50. In the process, impurities contained in the electrolyte are removed. After that, the electrolytic solution from which the foreign matter is removed flows into the cooling means 70. Here, the circulation of the electrolyte is of course made by the pump 60 installed in the line between the cooling means 70 and the filter 50.

냉각 수단(70) 내로 유입된 전해액은 내부에 설치된 방열기를 통과하는 과정에서 팬에 의한 냉각 과정을 거치게 된다. 팬에 의하여 공급되는 비교적 낮은 온도의 공기는 전기 분해 과정에서 가열된 전해액을 적절한 온도로 냉각시키며, 이후 냉각된 전해액은 제 2 전해액 순환 라인(L2)을 통하여 각 전해조들(10 및 20) 내부로 공급된다.The electrolyte introduced into the cooling means 70 undergoes a cooling process by a fan in the course of passing through the radiator installed therein. The relatively low temperature air supplied by the fan cools the heated electrolyte solution to an appropriate temperature during the electrolysis process, and then the cooled electrolyte flows into the respective electrolytic baths 10 and 20 through the second electrolyte circulation line L2. Supplied.

한편, 전해액 공급 탱크(30)의 제 4 연결부(34) 및 전해액 공급 라인(L3)을 통하여 새로운 전해액이 배출되며, 이 전해액은 냉각 수단(70)에서 배출되는 냉각된 전해액과 함께 전해조들(10 및 20) 내부로 공급된다. 이와 같이 전해액 공급 탱크(30) 내에 저장된 전해액이 전해조(10 및 20)로 공급되면 그 수위가 낮아지게 되며, 이 때 기액 분리기(40) 하부 공간에 저장된 물을 전해액 공급 탱크(30)로 공급한다.Meanwhile, new electrolyte is discharged through the fourth connecting portion 34 of the electrolyte supply tank 30 and the electrolyte supply line L3, and the electrolyte is discharged from the cooling means 70 together with the cooled electrolyte 10. And 20) supplied internally. As such, when the electrolyte stored in the electrolyte supply tank 30 is supplied to the electrolytic baths 10 and 20, the water level is lowered. At this time, the water stored in the space below the gas-liquid separator 40 is supplied to the electrolyte supply tank 30. .

즉, 사용자가 전해액 공급 탱크(30) 내의 수위를 감지한 후, 기액 분리기 (40)와 전해액 공급 탱크(30)를 연결하는 라인에 설치된 밸브(V)를 개방함으로서 기액 분리기(40) 내에 저장된 물은 전해액 공급 탱크(30)로 유입되며, 전해액 공급 탱크(30) 내의 수위가 적정 수위에 도달하면 밸브(V)를 밀폐시켜 물의 공급을 중지한다.That is, after the user senses the water level in the electrolyte supply tank 30, the water stored in the gas liquid separator 40 by opening the valve V installed in the line connecting the gas liquid separator 40 and the electrolyte supply tank 30. The silver flows into the electrolyte supply tank 30, and when the water level in the electrolyte supply tank 30 reaches an appropriate level, the valve V is sealed to stop supply of water.

이때, 전해액 공급 탱크(30)에서는 상술한 바와 같이 수산 가스에 함유되어있는 전해질인 KOH가 용해된 상태이기 때문에 새로운 물이 공급될 지라도 전해액의 농도는 적정 수준을 유지하게 된다.At this time, in the electrolyte supply tank 30, as described above, since KOH, which is an electrolyte contained in the hydroxide gas, is dissolved, the concentration of the electrolyte is maintained at an appropriate level even if fresh water is supplied.

한편, 도 2 내지 도 5는 본 발명을 구성하는 상술한 각 부재들을 단일 케이싱 내부에 배치하여 완전한 수산 가스 발생 장치를 구현한 상태를 도시하였으며, 그 연결관계와 기능은 위에서 설명한 바와 동일함은 물론이다.Meanwhile, FIGS. 2 to 5 show a state in which the above-described members constituting the present invention are disposed inside a single casing to implement a complete OH gas generating device, and the connection relations and functions thereof are the same as described above. to be.

이상과 같은 본 발명은 전기 분해가 이루어진 전해액을 필터, 열 교환기 등의 전해액 순환부를 통하여 강제 순환시킴으로서 전기 분해과정에서 형성된 이물질이 제거되고 적정 온도를 갖는 전해액을 전해조에 계속적으로 공급할 수 있어 최적의 조건에서 전기 분해 공정을 진행할 수 있다.The present invention as described above is forced to circulate the electrolyzed electrolyte through the electrolyte solution circulation section, such as a filter, heat exchanger to remove foreign substances formed during the electrolysis process can be supplied to the electrolytic cell with an electrolyte having a proper temperature for optimum conditions The electrolysis process can proceed.

또한, 전해액의 전기 분해 과정후 발생된 수산 가스에 함유되는 수산화 칼륨을 완전하게 분리, 제거함으로서 수산 가스의 순도(純度)를 향상시킬 수 있으며, 그 결과 수산 가스를 사용하는 외부 장치, 예를 들어 연소 장치의 연소 수단의 막힘 현상을 방지할 수 있는 효과를 얻을 수 있다. 이와 함께, 수산가스에서 제거된 전해질 즉, 수산화 칼륨과 기액 분리기를 통하여 새롭게 공급된 물, 즉 전해액을 각 전해조에 재 공급함으로서 새로운 전해액의 공급이 필요 없게 된다.In addition, by completely separating and removing the potassium hydroxide contained in the hydroxide gas generated after the electrolysis process of the electrolyte, the purity of the hydroxide gas can be improved, and as a result, an external device using the hydroxide gas, for example, The effect which can prevent the clogging phenomenon of the combustion means of a combustion apparatus can be acquired. In addition, by supplying freshly supplied water, that is, an electrolyte solution through the electrolyte removed from the hydroxide gas, that is, potassium hydroxide and a gas-liquid separator, it is unnecessary to supply a new electrolyte solution.
