본 발명은 온수보일러용 팽창탱크 부설 폐열회수기에 관한 것이다.The present invention relates to a waste heat recovery device attached to the expansion tank for hot water boiler.

주지하는 바와 같이 온수보일러는 통상적으로 가열수조에 팽창탱크를 일정높이로 설치하여 가열수조에 보충수(급수)를 공급하고 가열수조 내의 온수의 체적팽창 또는 이상팽창시에 그 팽창압력을 흡수함과 아울러 기포를 배출하고 있다.As is well known, a hot water boiler is usually installed with an expansion tank in a heating tank to supply a supplementary water (water supply) to the heating tank, and absorbs the expansion pressure during volume expansion or abnormal expansion of the hot water in the heating tank. At the same time, it is releasing bubbles.

상기한 팽창탱크는 밀폐형 팽창탱크와 개방형 팽창탱크로 대별되며, 상기한 것중 개방형 팽창탱크가 비용 및 관리측면에서 널리 사용되고 있다.The expansion tank is classified into a closed expansion tank and an open expansion tank, among which the open expansion tank is widely used in terms of cost and management.

상기한 개방형 팽창탱크의 일예가 1994년 실용신안출원공고 제 850 호 공보에 개시되어 있는바, 상기한 개방형 팽창탱크는 보충수통(탱크본체)의 하단부를 팽창겸 보충수 공급관으로 가열수조의 상부에 연결한 난방송수관에 연결하고, 상기 보충수통에 뚜껑을 설치함과 아울러 그 상부 일측에 배출구(오버 플로구)를 타측에 급수밸브를 설치하며, 상기 급수밸브에 부구를 설치하여서, 상기 보충수통 내에 부구에 의하여 제어되는 급수가 보충수로서 일정량 저장되어 있는 것인바, 상기 보충수통은 가열수조내에서 가열하려는 온수가 부족하면 보충수통 내에 저장된 보충수가 팽창겸 보충수 공급관을 통하여 가열수조에 급수로서 보충 공급되고, 그리고 가열수조 내의 체적팽창 또는 이상팽창시에 그 팽창압력은 팽창겸 보충수 공급관을 경유하여 보충수통으로 기포와 함께 배출되어 가열수조 내의 팽창압력을 흡수하면서 수증기는 배출구를 통하여 외부로 방출되는 것이다.An example of the open type expansion tank is disclosed in Utility Model Application Publication No. 850 of 1994. The open type expansion tank has an upper end of the supplementary water tank (tank main body) by expanding and supplementing the water supply pipe to the upper portion of the heating tank. It is connected to the non-recessed water pipe connected to the water supply valve, a lid is provided on the replenishing water tank, and an outlet port (overflow port) is installed on the other side of the water supply valve on the other side, and a water outlet is installed on the water supply valve. The water controlled by the mouth is stored in a certain amount as the replenishing water. When the replenishing water tank lacks hot water to be heated in the heating water tank, the replenishing water stored in the watering tank is expanded and supplied to the heating water tank through the replenishing water supply pipe. And the expansion pressure at the time of volume expansion or abnormal expansion in the heating water tank is supplemented via the expansion and make-up water supply pipe. As is discharged with the air bubbles while absorbing the expansion pressure in the heating tank water vapor it is discharged to the outside through the exhaust port.

또한 보충수통 내의 보충수의 수위가 낮아지면 부구가 하강함에 따라 급수밸브가 열리고 급수탱크 내에 저장된 급수가 보충수통에 보충수로서 공급되고, 급수가 일정수위 이상 공급되면 부구가 상승하여 급수밸브를 폐쇄하는 것이다.In addition, if the water level in the replenishing water drops, the water supply valve opens as the water supply drops, and the water stored in the water supply tank is supplied as the water supply to the water supply water supply, and when the water supply is above a certain level, the water supply rises to close the water supply valve. It is.

한편 상기 수증기는 가열수조에서 체적팽창 또는 이상팽창시에 그 팽창압력을 흡수하기 위하여 탱크본체로 배출되는 온수의 표면에서 표면증발에 의하여 발생되거나 가열수조에서 온수의 체적팽창시 등에 그 팽창압력을 흡수하기 위하여 탱크본체로 온수와 기포(용존산소)가 함께 배출되면서 기포팽창 또는 자기증발에 의하여 발생하는 것 등임으로 이의 발생을 억제할 수 없는 것이다.Meanwhile, the water vapor is generated by surface evaporation on the surface of the hot water discharged to the tank body to absorb the expansion pressure during volume expansion or abnormal expansion in the heating tank, or absorbs the expansion pressure during volume expansion of the hot water in the heating tank. In order to discharge the hot water and bubbles (dissolved oxygen) together to the tank body in order to occur due to expansion or self-evaporation, etc., it is impossible to suppress their occurrence.

그러나 상기한 팽창탱크는 탱크본체 내의 수증기를 배출구를 통하여 외부로 방출하고 있음으로 즉 수증기를 폐기하고 있음으로 에너지 손실이 막대하게 되는 것이다.However, the expansion tank discharges water vapor in the tank body to the outside through the discharge port, that is, the water vapor is discarded, so that the energy loss is enormous.

또한 상기와 같이 수증기를 방출하면 가열수조 내에서 가열하려는 온수도 비례하여 감소됨으로 감소된 양만큼의 보충수를 보충하여야 하며, 상기 보충수는 일반적으로 수돗물 또는 우물물을 사용하고 있고, 상기 수돗물 또는 우물물에는 불순물인 유산칼슘(CaSO4), 염화칼슘(CaCl2), 규산(SiO2), 중탄산 칼슘(Ca(HCo3)2) 등과 산소, 탄산가스 등을 용해하고 있음으로 전열면에 관석이 부착되어 열전달을 방해하여 효율이 저하되고 전열면의 부식 등을 초래하는바, 상기와 같이 수증기가 방출된 양만큼의 보충수가 공급되면 그 보충수량에 비례하여 새로운 불순물 등이 추가됨으로써 열전달 효율이 더욱더 저하되는 문제점이 발생하는 것이다.In addition, when the water vapor is discharged as described above, the hot water to be heated in the heating bath is also proportionally reduced, so the supplemented water must be replenished in a reduced amount, and the supplemental water generally uses tap water or well water, and the tap water or well water It is dissolved in impurities such as calcium lactate (CaSO 4 ), calcium chloride (CaCl 2 ), silicic acid (SiO 2 ), calcium bicarbonate (Ca (HCo 3 ) 2 ), oxygen, carbon dioxide, etc. Interfering with the heat transfer, the efficiency is lowered, which causes corrosion of the heat transfer surface. When the supplemental water is supplied as much as the amount of water vapor released as described above, new impurities are added in proportion to the supplemental water amount, thereby further reducing the heat transfer efficiency. The problem arises.
