Description
본 발명은 복합방식 압축공기 제습청정 장치에 관한 것으로 보다 상세하게 설명하자면 산업에 널리 이용되는 압축공기는 컴프레셔에 의한 압축과정에서 윤활유의 유분과 먼지 및 습기 등을 포함하고 있어 의료용, 식음료 공업 또는 정밀전자 산업분야와 같이 고청정도의 공기를 필요로 하는 분야에서는 직접 사용할 수 없으므로 이를 효과적으로 제습할 수 있게 한 장치에 관한 것이다.The present invention relates to a complex type compressed air dehumidifying and cleaning device. More specifically, the compressed air widely used in the industry includes oil, dust, and moisture of lubricating oil in the compression process by a compressor, and thus the medical, food and beverage industry or precision. The present invention relates to a device that enables effective dehumidification because it cannot be used directly in a field requiring high clean air, such as the electronics industry.
일반적으로 공기중의 습기를 제거하는 장치로는 접촉되는 표면부의 온도가 공기온도 보다 낮으면 접촉부에 공기중의 수분이 응축되는 현상을 이용하는 냉각식 제습기, 공기를 압축하고 압축된 공기를 냉각하면 포화수분이 응축하는 현상을 이용하는 압축식 제습기, 염화리듐 용액과 같은 흡수제로 수분을 흡수하는 흡수식 제습기, 실리카겔과 같은 흡착성 물질을 이용하여 공기중의 수분을 제습하는 흡착식 제습기 등 여러가지 방식의 제습기가 있으며, 냉각식 제습기에는 냉매 압축식 냉각기를 이용하는 방식과 펠티어(Feltier) 효과를 이용하는 열전반도체 방식으로 나누어 볼 수 있다.Generally, a device that removes moisture from the air is a cooling dehumidifier that uses a phenomenon in which water in the contact portion is condensed when the temperature of the contacted surface is lower than the air temperature. There are various types of dehumidifiers such as compressed dehumidifiers that take advantage of the condensation of moisture, absorbent dehumidifiers that absorb moisture with an absorbent such as lithium chloride solution, and adsorptive dehumidifiers that dehumidify moisture in the air by using an adsorbent such as silica gel. Cooling dehumidifiers can be divided into a method using a refrigerant compression cooler and a thermoelectric semiconductor method using the Peltier effect.
종래 산업용 압축공기 제습장치로는 냉각식 제습기나 흡수식 제습기가, 건물의 공조설비나 상대적으로 청정도가 낮은 공기를 필요로 하는 분야에는 펠티어 효과를 이용한 열전반도체 방식이 이용되었으며 흡착식은 그 구성이 단순함으로 인하여 압축공기를 이용하는 운송기계등의 부품으로 이용되었다.Conventional industrial compressed air dehumidifier is a cooling dehumidifier or absorption dehumidifier, a thermoelectric semiconductor method using the Peltier effect is used in the air conditioning facilities of buildings and relatively low clean air, and the adsorption type is simple. Due to this, it was used as a part of a transportation machine using compressed air.
그러나 상기와 같은 하나의 방식을 이용하는 제습장치는 고청정도의 공기를 얻기 어렵다는 문제점이 있거나 고청정도의 제습을 위하여는 설비가 커진다는 문제점이 있었다.However, the dehumidifying apparatus using one of the above-described methods has a problem that it is difficult to obtain a high degree of clean air, or a problem that a facility becomes large for high degree of dehumidification.
상기한 문제점을 해결하기 위한 본 발명의 기술적 과제는 하나의 제습방식만으로는 고청정도의 압축공기를 얻기 어렵다는 점을 감안하여 보다 간편하고 효율적인 복합방식의 압축공기 제습장치를 제공하는 것을 목적으로 한다. The technical problem of the present invention for solving the above problems is to provide a compressed air dehumidification apparatus of a simple and efficient complex method in consideration of the difficulty in obtaining a compressed air of high cleanness with only one dehumidification method.
본 발명은 상기한 목적을 달성하기 위하여 컴프레셔에서 압축된 공기는 에어필터를 통하여 부유성 고형물질인 먼지 등을 우선 제거하고 컴프레셔에서 단열압축되어 온도가 상승된 공기를 냉각시켜 포화수분을 제습하는 냉매압축식 제습방법을 통하여 1차적으로 제습한 다음 활성탄을 이용한 필터를 통하여 윤활유의 유분과 에어필터에서 제거되지 않는 미세한 고형물질 및 가스를 흡착 제거한 후 2차적으로 펠티어 효과를 이용한 열전반도체를 이용하는 제습기로 제습하여 고청정도를 가진 압축공기를 얻을 수 있게 하는 것을 특징으로 한다.In order to achieve the above object, the compressed air in the compressor removes dust, which is a floating solid material, first through an air filter, and is adiabaticly compressed in the compressor to cool the air having an elevated temperature to dehumidify saturated moisture. Dehumidification is first performed through a compressed dehumidification method, and the adsorption and removal of the oil and lubricating oil and fine solids that are not removed from the air filter through the filter using activated carbon is used as a dehumidifier using a thermoelectric semiconductor using the Peltier effect. Dehumidification is characterized in that to obtain compressed air having a high degree of cleanliness.
이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예에 대하여 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명을 설명하기에 앞서 본 발명의 요지를 불명료하게 하지 않게 하는 범위 내에서 당업자에 의하여 용이하게 실시할 수 있는 공지된 구성에 대하여는 구체적인 설명을 생략하여 본 발명의 특징을 보다 명확하게 하기로 한다.Prior to describing the present invention, a well-known configuration that can be easily implemented by those skilled in the art without departing from the gist of the present invention will be omitted to clarify the features of the present invention. .
도 1은 본 발명 복합방식 압축공기 제습청정 장치의 개념도이다.1 is a conceptual diagram of a composite type compressed air dehumidifying and cleaning device of the present invention.
도 1에 도시된 바와 같이 에어컴프레셔에서 압축되는 공기는 부유성 고형물질인 먼지와 컴프레셔 윤활유의 유분과 습기를 포함하고 있다.As shown in FIG. 1, the air compressed in the air compressor includes oil and moisture of a floating solid material, dust, and a compressor lubricant.
따라서 제습작업 이전에 먼지 등을 1차로 제거하는 것이 필요하며 먼지의 제거는 통상의 에어필터 Ⅰ(1)을 사용하여 비교적 큰 입자의 먼지를 우선 제거한다.Therefore, it is necessary to first remove dust and the like before the dehumidification operation, and the dust is first removed using the conventional air filter I (1).
컴프레셔(2)에 의하여 단열 압축된 공기는 압축된 체적에 반비례하여 온도가 상승하며 온도가 상승된 압축공기를 냉각하면 포함된 습기는 포화상태가 되어 잉여습기는 응축된다.The air adiabatic compressed by the compressor 2 rises in inverse proportion to the compressed volume, and when the compressed air whose temperature rises is cooled, the contained moisture becomes saturated, and excess moisture condenses.
응축된 수분은 자중에 의하여 자연 낙하되어 냉각기 하단의 집수통(도면 미도시)에 고이게 되며 집수통에는 수분감지 센서(도면 미도시)를 구비하여 일정량 이상의 수분이 고이면 드레인벨브(도면 미도시)를 개방하여 자동방출 되게 구성한다.The condensed water naturally falls due to its own weight and accumulates in the sump (not shown) at the bottom of the cooler. The sump is equipped with a moisture detection sensor (not shown) and a drain valve (not shown) is provided when a certain amount of moisture is accumulated. It is configured to open automatically.
압축된 공기를 냉각하는 데에는 설치장소에 제약이 없다면 쿨링타워와 같은 장치를 냉매압축식 제습기와 병행 설치하여 제습기의 효율을 높일 수도 있다.If there is no restriction on the location of cooling the compressed air, a device such as a cooling tower may be installed in parallel with the refrigerant compression dehumidifier to increase the efficiency of the dehumidifier.
에어필터 Ⅰ(1)과 냉매압축식 제습기(3)에서 1차적으로 먼지와 습기가 제거된 압축공기는 에어필터 Ⅱ(4)에서 재차 필터링 된다.In the air filter I (1) and the refrigerant compression type dehumidifier (3), the compressed air from which dust and moisture are first removed is again filtered by the air filter (II).
에어필터 Ⅱ(4)는 공기의 청정도를 향상시키기 위하여 미분말의 활성탄을 이용한 필터로 부유성 고형물질은 물론 유해가스와 유분을 흡착제거할 수 있으며 필터링된 공기중의 유분은 0.005 PPM 이하로 유지할 수 있게 한다.Air Filter II (4) is a filter using activated carbon of fine powder to improve air cleanliness. It can adsorb and remove suspended solids as well as harmful gases and oils. To be.
에어필터 Ⅱ(4)에서 재 여과된 압축공기는 열전반도체 소자식 제습기(5)에서 2차로 제습하며 2차제습이 끝난 압축공기는 상온에서 98% 이상 건조된 공기를 얻을 수 있게된다.The compressed air re-filtered by the air filter II (4) is dehumidified by the thermoelectric element type dehumidifier (5) secondly, and the compressed air after the second dehumidification is able to obtain air dried at room temperature of 98% or more.
도 2는 열전반도체 소자식 제습장치의 원리에 관한 것으로 열전반도체(12)는 펠티어 효과를 이용한 것이고 펠티어 효과란 두 종류의 서로 다른 금속을 접촉시켜 전류를 흘려보내면 전류의 방향에 따라 한쪽 단자에는 흡열효과가, 다른쪽 단자에는 발열효과를 일으키는 현상을 말하며,2 is related to the principle of the thermoelectric semiconductor element type dehumidifier. The thermoelectric semiconductor 12 uses the Peltier effect, and the Peltier effect is an endotherm at one terminal according to the direction of the current when the current flows by contacting two different metals. The effect is the phenomenon that causes the heating effect on the other terminal,
이는 this is
= 펠티어계수, = 전류, = 단위시간에 발열하는 열량의 절대값, = 주위 온도에 따른 두금속의 상대열 전능의 식으로 나타낼수 있다. = Peltier coefficient, = Current, = Absolute value of heat generated in unit time, = According to ambient temperature It can be expressed by the formula of relative thermal omnipotence of two metals.
펠티어 효과는 두가지 서로 다른 금속들간의 접합을 거쳐 전류가 흐를 때 일어나는 열의 방출과 흡수를 의미하며 전류가 어떤 한 방향으로 흐를 때 열이 발생된다면 전류가 그 반대 방향으로 흐르면 열을 흡수하기 때문에 펠티어 효과는 가역적이다.The Peltier effect is the release and absorption of heat that occurs when a current flows through a junction between two different metals.The Peltier effect absorbs heat when current flows in the opposite direction if heat is generated when current flows in one direction. Is reversible.
접합에 전류가 흐르면 도체에 전류가 흐를 때 발생하는 줄(Joule)열 효과에 추가하여 펠티어 효과에 의한 열발생이나 흡수가 발생한다.When current flows through the junction, heat generation or absorption by the Peltier effect occurs in addition to the Joule thermal effect generated when the current flows through the conductor.
도 3은 열전반도체 소자식 제습장치의 단면도이다.3 is a cross-sectional view of a thermoelectric semiconductor element dehumidifier.
열전 반도체 소자를 이용하는 냉각방식은 냉매압축식에 비하여 고전류에서는 작동할 수 없어, 비효율적이지만 소음이 없고 소형화가 가능하므로 특수용으로 널리 사용된다.The cooling method using the thermoelectric semiconductor device is inefficient, but can be operated at a high current compared to the refrigerant compression type, it is inefficient but noiseless and can be miniaturized, so it is widely used for special purposes.
따라서 펠티어 효과를 효율적으로 이용하기 위하여는 냉매압축식 냉각기와는 다른 구성을 필요로 하며 도 3은 하나의 실시 예로서 다수의 열전도성이 높은 박막으로된 격벽(6)을 양측에서 서로 엇갈리게 배치하여 흡열부(10)를 구성하고 격벽사이의 간극으로 공기를 통과시켜 제습하는 구조이다.Therefore, in order to effectively use the Peltier effect, a configuration different from that of a refrigerant compression type cooler is required, and FIG. 3 illustrates an example in which a plurality of thermally conductive partition walls 6 are alternately arranged at both sides. It constitutes a heat absorbing portion 10 and dehumidifies by passing air through a gap between partition walls.
상기 격벽(6)은 펠티어 효과에 의한 흡열작용으로 압축공기보다 저온상태에 있으므로 공기중에 포함된 습기는 격벽의 표면에서 응축된다.Since the partition 6 is at a lower temperature than compressed air due to the endothermic action by the Peltier effect, moisture contained in the air condenses on the surface of the partition.
하나의 격벽에 의한 제습효과는 크지 않지만 다수의 격벽으로 흡열부(10)를 형성하여 충분한 제습목표 달성이 가능하다.Dehumidification effect by one partition is not great, but it is possible to achieve a sufficient dehumidification target by forming the heat absorbing portion 10 to a plurality of partitions.
격벽의 표면에 응축된 응축수는 자중에 의하여 아래로 낙하되어 집수통(7)에 집수되고 집수통에 구비된 센서(8)에 의하여 일정 수위에 도달하면 드레인벨브(9)를 자동 개폐하여 외부로 방출한다.The condensate condensed on the surface of the partition falls down by its own weight and is collected in the sump (7). When the water level reaches a certain level by the sensor (8) provided in the sump, the drain valve (9) is automatically opened and closed. Release.
또한 흡열작용을 하는 격벽은 그 끝부분이 아래로 향하도록 다소 경사진 형태를 구성하여 응축수의 낙하를 보다 용이하게 구성하는 것이 바람직하며 발열부(11)에는 방출되는 열을 냉각 시키기 위하여 팬(14)이 구비된다.In addition, the endothermic partition wall is configured to be slightly inclined so that its end portion is downward, so that the condensate falls more easily, and the heat generating part 11 may cool the fan 14 ) Is provided.
이상에서 설명한바와 같이 본 발명 복합방식의 제습기는 단일 형식의 제습방식에 비하여 보다 효율적으로 고청정도의 건조공기를 얻을 수 있으며 청정도에 따른 에너지의 소비비용도 절감할 수 있는 효과가 있다.As described above, the combined type dehumidifier of the present invention can more efficiently obtain dry air having a higher degree of cleanness than a single type of dehumidification method, and can reduce energy consumption cost according to cleanliness.
