즉, 드라이클리닝이라는 유기용제를 사용하는 세탁의 경우 건조 시에 유기용제는 건조기(10)내에서 휘발되어 대기 중으로 방출되던 것을 하단부에 배기되고 상부로 유입되는 밀폐된 기체순환관(20)을 통한 순환구조를 구성하고, 도료공장 등에서 대량 사용하는 유기용제는 유기용제용기(10-1)의 상부에 휘발된 기체를 기체순환관(20)을 통한 밀폐 순환구조로 하고, 기체순환관(20)의 중간에 열교환기(40), 열전소자(50)을 사용하는 냉각 응축장치를 구성하여, 응축되는 유기용제를 응축수수집관(60)을 통하여 유수분리기(61)에 모아 회수하고, 나머지 기체는 밀폐공간에서 순환되도록 구성되어있다.That is, in the case of washing using an organic solvent called dry cleaning, the organic solvent is volatilized in the dryer 10 at the time of drying and exhausted into the atmosphere through the closed gas circulation tube 20 which is exhausted to the lower end and flows into the upper part. Organic solvents constituting the circulation structure, and used in large quantities in the paint factory, etc., the gas volatilized on the upper portion of the organic solvent container (10-1) to the closed circulation structure through the gas circulation pipe 20, the gas circulation pipe (20) In the middle of the configuration of the cooling condenser using the heat exchanger 40, the thermoelectric element 50, the organic solvent to be condensed through the condensate collection pipe 60 collected in the oil and water separator (61), and the remaining gas It is configured to circulate in a confined space.

본 고안을 도면을 들어서 상세히 설명하면,When the present invention is described in detail with reference to the drawings,

도1에서, 세탁물을 건조기(10)에 넣고 건조할 때 상부의 건조가열부(11)의 열기(70℃-80℃)는 배기용팬(13)에 의하여 세탁물을 건조시키고 하부로 이동 기체순환관(20)을 통하여 순환과정을 거치게 된다.In FIG. 1, when the laundry is put into the dryer 10 and dried, the hot air (70 ° C.-80 ° C.) of the upper drying heating part 11 dries the laundry by the exhaust fan 13 and moves the gas circulation pipe downward. Through 20 it goes through a cycle.

이때 기체는 증발 되는 수분과 유기용제 등이 혼합된 기체이고, 이 기체는 기체순환관(20)을 지나 유기용제유무분리밸브(21)에서 유기용제의 함유가 선택되면 훨터(30)에서 각종 이물질이 걸러지고 수분이 함유된 유기 기체는 열교환기(40)를 통과 하면서 열교환기팬(41)에 의하여 일차 냉각되고, 다시 열전소자(50)로 만들어진 냉각 응축기를 통과하게 되는데, 열전소자는 펠티어효과에 의하여 직류전기를 인가하면 한 측은 즉 (+)로 대전된 측은 발열을하고 (-)로 대전된 측은 흡열을 즉 냉각을 하게 되는 성질을 이용, 냉각부(51)에 기체순환관(20)을 밀착하게 구성하고 단열부(52)를 구성 단열을 하여 외부의 열 유입을 차단하고, 발열부(53)에는 방열이 잘되는 히트싱크로 구성하여 냉각팬(54)을 통하여 방열함으로 냉각효과를 극대화 하도록 구성한다.At this time, the gas is a gas mixed with the evaporated water and the organic solvent, this gas is passed through the gas circulation tube 20, if the organic solvent is contained in the organic solvent-free separation valve 21 is selected, various foreign matters in the floater 30 The filtered and moisture-containing organic gas is first cooled by the heat exchanger fan 41 while passing through the heat exchanger 40, and then passes through a cooling condenser made of the thermoelectric element 50. The thermoelectric element is subjected to the Peltier effect. When the direct current is applied, one side, that is, the positively charged side generates heat and the negatively charged side heats the endothermic, ie, cools the gas circulation tube 20 to the cooling unit 51. It is configured to be in close contact with the heat insulating part 52 to block heat inflow from the outside, and the heat generating part 53 is configured to be a heat sink with good heat dissipation, and is configured to maximize the cooling effect by heat dissipation through the cooling fan 54. do.

상기의 냉각부(51)는 냉각이 되어 여기를 지나는 수분과 유가용제를 함유한 순환기체는 응축이 되어 응축수수집관(60)을 통하여 유수분리기(70)에 모이게 되고, 공기는 기체순환팬(22)에 의하여 기체순환관(20-1)을 통하여 건조기로 다시 들어가는 순환과정을 거친다.The cooling unit 51 is cooled and the circulation gas containing the water and the oil solvent passing therethrough is condensed and collected in the oil / water separator 70 through the condensate collection pipe 60, and the air is a gas circulation fan ( 22) through the gas circulation tube (20-1) goes through the circulation process to enter the dryer again.

상기의 휠터(30)는 정기적으로 교체를 해야 그 기능을 유지할 수 있음으로 교체를 원활하게 할 수 있도록 힌지와 팩킹 등을 이용, 휠터교체구(31) 만들어 휠터의 원활한 교체와 밀폐가 잘 되도록 구성한다.The filter 30 is to be replaced regularly to maintain its function, using a hinge and packing, etc. to facilitate the replacement, the replacement of the filter wheel 31 is made to facilitate the replacement and sealing of the filter well do.

상기의 유수분리기(70)에 모인 액체는 유기용제가 비중이 0.68-0.75정도로 물보다 낮아서 이 비중의 차이로 유기용제는 유기용제회수관(72)을 통하여 회수하고, 물은 배수관(71)을 통하여 배출함으로서 휘발된 유기용제는 회수하여 재활용 할 수 있고, 밀폐된 구조에서 이러한 순환을 반복함으로서 유기용제의 휘발로 인한 대기오염을 방지할 수 있고, 유기용제의 재활용을 통한 원가를 절감할 수 있는 것이다.In the liquid collected in the oil / water separator 70, the organic solvent has a specific gravity of about 0.68-0.75, which is lower than that of water, and the organic solvent is recovered through the organic solvent recovery pipe 72 due to the difference in specific gravity. Volatile organic solvent can be recovered and recycled by discharging through it, and by repeating this cycle in a sealed structure, air pollution can be prevented due to volatilization of organic solvent, and cost can be reduced through recycling of organic solvent. will be.

도2는 도료공장 등 유기용제를 사용하는 유기용제용기(10-1)의 상부에서 휘발되는 기체를 수집하여 기체순환관(20)을 통하여 밀폐 순환시키는 구조를 나타낸 예시도로 그 순환구조는 도1의 성명과 같다.FIG. 2 is an exemplary view showing a structure in which a gas volatilized at an upper portion of an organic solvent container 10-1 using an organic solvent, such as a paint factory, is airtightly circulated through the gas circulation tube 20. Is the same as

상기 열전소자(50)를 이용한 냉각 응축장치는 그 효율을 올리기 위하여 수냉 방식으로 할 수 있는데, 도3은 이것을 나타낸 것이다.The cooling condensation apparatus using the thermoelectric element 50 may be a water cooling method to increase the efficiency, Figure 3 shows this.

도3에서 열교환기(40)에서 일차 냉각된 혼합기체는 열전소자(50)를 이용한 냉각구조에서 흡열부(51)측에 접하여 단열부(52)로 단열되어있는 냉각 응축부를 통과 응축되어 응축수수집관(60)을 통하여 유수분리기(70)에 모이고, 기체는 기체순환팬(22)에 의하여 건조기에 다시 들어가게 된다.In FIG. 3, the mixed gas first cooled by the heat exchanger 40 is condensed through the cooling condensation part which is insulated by the heat insulating part 52 in contact with the heat absorbing part 51 side in the cooling structure using the thermoelectric element 50. Collected in the oil and water separator (70) through the tube (60), the gas is re-entered into the dryer by the gas circulation fan (22).

이때 발열부(53)는 상기 도1에서 설명한 바와는 달리, 히트싱크를 이용하지 않고 냉각수가 순환되는 블록구조로 하고 냉각수가 냉각기(55)에서 냉각팬(54-1)에 의하여 냉각되고 냉각수순환펌프(56)에 의하여 순환하는 구조를 구성함으로서 냉각 응축효율을 증대시킬 수 있다.At this time, unlike the heat generating unit 53 described above with reference to Figure 1, the cooling water is circulated without the use of a heat sink, the cooling water is cooled by the cooling fan 54-1 in the cooler 55 and the cooling water circulation By configuring the structure circulated by the pump 56, the cooling condensation efficiency can be increased.

상술한 바와 같이 본 고안은 세탁건조기나, 다량의 유기용제를 사용하는 공장에서 유기용제용기에서 휘발되는 유기용제를 밀폐 순환시켜 냉각 응축회수하여 재사용함으로, 유기용제의 대기 중 방출에 의한 대기오염을 방지하고, 유기용제의 재활용에 의한 원가를 절감하는 효과를 얻을 수 있다.As described above, the present invention is a laundry dryer or a factory using a large amount of organic solvents, and thus, the organic solvents volatilized in the organic solvent containers are circulated in a closed manner and reused by cooling condensation recovery, thereby preventing air pollution caused by the release of organic solvents into the atmosphere. It is possible to obtain an effect of reducing the cost by recycling the organic solvent.
