원예 온실용 온풍기{HOT AIR BLASTER FOR GREEN HOUSE OF HORTICULTURE}Hot air blower for gardening greenhouse {HOT AIR BLASTER FOR GREEN HOUSE OF HORTICULTURE}

본 발명은 원예 온실에 온풍을 공급하기 위한 원예 온실용 온풍기에 관한 것이다.The present invention relates to a hot air blower for horticultural greenhouses for supplying warm air to the horticultural greenhouse.

종래 원예(농예) 온실에서 사용되는 온풍기는 다양한 종류의 것이 사용되고 있으나 전기온풍기와 연료사용 온풍기로 대별되고 연료를 사용하는 온풍기는 고체연료와 액체연료를 사용하는 온풍기로 나누어진다.Conventional horticulture (horticulture) greenhouses are used in a variety of kinds of heat fans, but electric heaters and fuel-use hot air blower is divided into a hot air using a solid fuel and a liquid fuel.

액체열료를 사용하는 온풍기는 대부분 오일버너가 설치된 연소실과, 연소실에서 지그재그로 굴곡되게 연결된 배연관 및 연통이 관접된 배연실로 구성되어 있다. 또 상기한 온풍기는 배연관이 굴곡되어 있어도 굴곡면에 의한 방열면적의 증대효과가 크지 않기 때문에 연통으로 배출되는 열 손실이 커서 연소효율이 높지 못하고 연료소비에 비하여 온실에서의 열이용율이 높지 못하여 난방비가 높아지는 문제점이 있었다.The hot air heater using liquid heat is mostly composed of a combustion chamber in which an oil burner is installed, a flue gas pipe connected in a zigzag form in the combustion chamber, and a flue gas chamber in communication with each other. In addition, even if the flue pipe is curved, the heat dissipation area by the curved surface does not increase so much that the heat loss discharged through the communication is not high, and the combustion efficiency is not high and the heat utilization rate in the greenhouse is not high compared to fuel consumption. There was a problem that increases.

종래의 온풍기는 구조적으로 연소실에서 연소가스가 이동하는 배연관이 배연 실을 향하여 지그재그로 굴곡되게 구성되어 있으나, 배연관에 접촉된 일부의 연소가스만이 열교환작용이 이루어져 배연관의 주벽을 통하여 열이 방출 될뿐, 배연관의 내부 공간의 중앙부로 이동하는 많은 량의 연소가스는 배연관의 주벽과의 접촉을 통한 열교환작용이 거의 이루어지지 못하기 때문에 연통으로 배출되는 열손실이 크고 온실에서의 열이용율이 높지 못하며, 따라서 원예의 온실 에너지비용이 상대적으로 높아지는 문제점이 있었다.Conventionally, the hot air heater is structurally configured such that flue gas pipes in which combustion gas moves in the combustion chamber is zigzagly curved toward the flue gas chamber, but only a part of the flue gas in contact with the flue gas is heat-exchanged to heat through the main wall of the flue pipe. This large amount of combustion gas moving to the central part of the internal space of the flue pipe has little heat exchange effect through contact with the main wall of the flue pipe, so that the heat loss emitted through the communication is large, The heat utilization rate is not high, and therefore, there is a problem in that the greenhouse energy cost of gardening is relatively high.

본 발명의 목적은 고온영역과 저온영역의 온도차가 클 수록 열이 저온영역으로 신속하게 이동되는 물리적인 현상을 이용하여, 오일버너가 장착된 연소실과 연통이 구비된 배연실 사이에 고온영역을 조성하는 수단과 저온영역을 조성하는 수단을 구비하고 저온영역에 열을 반송(搬送)하는 유체를 지속적으로 공급하여 고온영역과 저온영역의 온도차를 크게 유지함으로서 신속한 열교환작용으로 열이용율을 보다 높일 수 있는 온풍기를 제공하려는데 있다.An object of the present invention is to create a high temperature zone between a combustion chamber equipped with an oil burner and a flue gas chamber equipped with communication by using a physical phenomenon in which heat is rapidly transferred to a low temperature region as the temperature difference between the high temperature region and the low temperature region increases. Means for forming a low temperature zone and continuously supplying a fluid that conveys heat to the low temperature zone to maintain a large temperature difference between the high temperature zone and the low temperature zone, thereby increasing heat utilization rate by rapid heat exchange. I'm trying to provide a warmer.

본 발명은 온풍기에 있어서, 통상의 오일버너가 설치된 온풍기의 연소실과 연통이 관접된 배열실의 사이에 고온영역을 조성하는 수단으로서 연소통에 비하여 상대적으로 내경이 작고 하니컴 형상의 세라믹축열재가 내장된 화염집속관을 관접하여 연소가스를 고밀도로 집속하여 연소작용을 촉진하여 고온을 유지할 수 있게 하고 상기 고온영역의 주위에 저온영역을 조성하는 수단으로서 화염집속관의 주면에 연소통의 반지름 크기의 다수의 방열판을 조밀하게 구비하고 열을 회수하는 수단으로서 연소통의 주위에 송풍공간을 두고 둘러싼 외통의 상부에 송풍기가 구비된 송풍관을 관접하여 구성된 것이다.The present invention relates to a hot air blower, which is a means for forming a high temperature region between a combustion chamber of a hot air heater equipped with a conventional oil burner and an arrangement chamber in communication with each other. It is a means of concentrating the combustion gas at a high density by contacting the flame concentrator tube to promote the combustion action to maintain a high temperature and forming a low temperature region around the high temperature region. The heat sink is densely provided and a means for recovering heat is configured by contacting a blower tube having a blower on an upper portion of the outer cylinder surrounding the blower space around the combustion cylinder.

본 발명에 의하면, 오일버너에서 공급된 공기와 액체연료가 연소실에서 연소된 다음 연소가스가 배출되는 배연실로 이동하는 과정에서 내경이 작은 화염집속관으로 유입되면서 연소가스 분자는 고밀도로 집속된다. 따라서 미연소가스 분자와 공기의 접촉이 증대되고 세라믹축열재의 고열에 접촉되면서 2차 연소작용이 증대되어 완전연소와 동시에 고열이 발생되어 고온영역을 조성한다.According to the present invention, while the air and liquid fuel supplied from the oil burner are combusted in the combustion chamber and then moved to the flue chamber where the combustion gas is discharged, the combustion gas molecules are concentrated at high density while being introduced into the flame concentrator tube having a small inner diameter. Therefore, as the contact between the unburned gas molecules and the air is increased and the high heat of the ceramic heat storage material is increased, the secondary combustion action is increased to generate high temperature region at the same time as the complete combustion.

한편, 낮은 온도영역의 방열판에는 송풍기로 부터 다량의 강력한 유체가 공급되어 방열판의 열을 외부로 반송한다. 따라서 방열판은 항상 저온을 유지하며, 고온영역의 화염집속관과, 저온영역의 방열판 간에는 온도차이가 크게 유지된다. 이러한 온도차이로 인하여 고온영역의 열이 저온영역으로 신속하게 이동된다.On the other hand, a large amount of strong fluid is supplied from the blower to the heat sink in the low temperature region to convey the heat of the heat sink to the outside. Therefore, the heat sink is always kept at a low temperature, and the temperature difference is largely maintained between the flame concentrator tube in the high temperature region and the heat sink in the low temperature region. Due to this temperature difference, heat in the high temperature region is quickly transferred to the low temperature region.

저온영역으로 이동된 열은 송풍된 유체에 의해 회수되어 온풍을 온실에 공급하기 때문에 연소실에서 1000℃ 이상으로 발열되면서 연소된 열이 거의 모두 회수되어 연통으로 방출되는 열이 불과 180℃를 넘지 않는다.Since the heat moved to the low temperature region is recovered by the blown fluid and supplies the warm air to the greenhouse, the heat generated at 1000 ° C. or higher in the combustion chamber is almost recovered, and the heat released through the communication does not exceed only 180 ° C.

또한 본 발명은 화염집속관의 길이와 방열판의 표면적과 방열판의 배열 밀도조건에 따라 방열량을 증대시킬 수 있으므로 온풍기의 구조가 작은면서 열의 회수율을 높일 수 있는 이점이 있다.In addition, the present invention can increase the amount of heat dissipation according to the length of the flame concentrator tube, the surface area of the heat sink and the array density condition of the heat sink, so that the structure of the hot air heater is small and the heat recovery rate can be increased.

본 발명은 오일버너가 장착된 연소실과 연통이 구비된 배연실 사이에 고온영역을 조성하는 수단과, 저온영역을 조성하는 수단을 구비하고 저온영역에 열을 반송(搬送)하는 유체를 지속적으로 공급하여 고온영역과 저온영역의 온도차를 크게 유지하는 수단으로 구성되어 있기 때문에 연소열의 신속한 열교환작용으로 열의 회수율이 높게 되어 열이용율을 보다 높일 수 있는 온실용 온풍기를 제공할 수 있다.The present invention includes a means for forming a high temperature region between a combustion chamber equipped with an oil burner and a flue gas chamber equipped with a communication unit, and a means for forming a low temperature region and continuously supplying a fluid for transferring heat to the low temperature region. Therefore, since it is composed of a means for maintaining a large temperature difference between the high temperature region and the low temperature region, it is possible to provide a greenhouse hot air fan that has a high heat recovery rate due to a rapid heat exchange action of combustion heat.

또한 종래의 것에 비하여 구조가 간단하여 운반및 취급이 간편하고 온실의 난방 유지가 보다 절감되어 각종 원예의 온실에 유용하게 사용할 수 있는 효과가 있다.In addition, the structure is simpler than the conventional one, the transportation and handling is easy, and the heating maintenance of the greenhouse is further reduced, so that it can be usefully used for greenhouses of various gardening.

FIG. 2 is a cross-sectional view of the present invention. Between the combustion cylinder 2 provided with the combustion chamber 2a of the hot air blower 1 in which the normal oil burner B was installed, and the flue gas cylinder 3 provided with the arrangement chamber 3a in which the communication 3b was connected. The high temperature region H is formed by contacting the flame condenser tube 4 in which the internal diameter is relatively small compared to the internal diameter of the combustion cylinder 2 and the honeycomb-shaped ceramic heat storage material 4s is embedded. In the length range of the flame concentrating tube 4, a plurality of circular heat sinks 5 of approximately the same size as the inner diameter of the combustion cylinder 2 are arranged in dense parallel to the main surface of the flame connecting tube 4 so that the high temperature region ( A low temperature region L is formed around H). Hot air outlets 6b are provided on both end sides of the outer cylinder 6 surrounding the combustion cylinder 6 and the flue cylinder 3 with the air blowing space 6a, respectively, and the motor 7m on the upper side of the outer cylinder 6. And a heat recovery means in contact with the blower tube 7a provided with the blower 7 driven by the blower, and continuously supply the heat transfer fluid to the heat dissipation plate 5 of the low temperature region L. By maintaining a large temperature difference between the region (H) and the low temperature region (L) it is configured to increase the heat recovery rate.

이와 같이 구성된 본 발명에 의하면, 오일버너(B)에서 공급된 공기와 액체연료가 연소통(2)의 연소실(2a)에서 연소된 다음 연소실(2a)의 내부 압력에 의해 연 소가스가 배연통(3)의 배연실(3a)로 이동하는 과정에서 내경이 작은 화염집속관(4)으로 유입되면서 연소가스 분자는 고밀도로 집속된다. 따라서 미연소가스분자와 공기분자의 접촉이 증대되고 또한 세라믹 축열재의 고온에 접촉되어 2차 연소작용이 촉진되어 완전 연소되는 동시 고온의 열이 방출되어 고온영역(H)이 조성된다.According to the present invention configured as described above, the air and liquid fuel supplied from the oil burner (B) are burned in the combustion chamber (2a) of the combustion cylinder (2), then the combustion gas is flue gas communication by the internal pressure of the combustion chamber (2a) In the process of moving to the combustion chamber 3a of (3), the combustion gas molecules are concentrated at a high density as they flow into the flame concentrator tube 4 having a small inner diameter. Therefore, the contact between the unburned gas molecules and the air molecules is increased, and the secondary combustion action is promoted by contacting with the high temperature of the ceramic heat storage material, thereby releasing the simultaneous high temperature heat that is completely burned, thereby forming the high temperature region (H).

한편, 저온영역(L)의 방열판(5)에는 송풍기(7)로 부터 다량의 강력한 공기가 공급되어 방열판(5)의 열을 외부로 반송되어 저온으로 된다. 따라서 화염집속관(4)의 고온영역(H)과 방열판(5)의 저온영역(L) 간에는 온도차이가 크게 된다. 이러한 온도차이로 인하여 고온영역(H)의 열이 저온영역(L)으로 신속하게 이동된다.On the other hand, a large amount of powerful air is supplied from the blower 7 to the heat sink 5 of the low temperature region L, and the heat of the heat sink 5 is conveyed to the outside to become a low temperature. Therefore, the temperature difference becomes large between the high temperature area | region H of the flame concentrating pipe 4, and the low temperature area | region L of the heat sink 5. Due to this temperature difference, heat in the high temperature region H is quickly moved to the low temperature region L. FIG.

저온영역(L)으로 이동된 열은 반송매체인 송풍된 유체에 의해 회수되어 온풍구(6b)를 통하여 온실에 공급된다.Heat moved to the low temperature region (L) is recovered by the blown fluid as a carrier medium and supplied to the greenhouse through the hot air vent (6b).

본 발명의 온풍기는 연소통과 배연통 사이에 고온영역을 조성하는 화염집속관과, 저온 영역을 조성하는 조밀하게 배치된 다수의 방열판을 구비하여 구성하였기 때문에 종래의 온풍기에 비하여 구조가 간단하면서 열교환작용이 양호하여 온풍기의 열회수율이 크고 온실에서의 열이용율을 보다 높일 수 있는 것이다.The hot air heater of the present invention comprises a flame concentrator tube that forms a high temperature region between the combustion cylinder and the flue cylinder, and a plurality of heat sinks that are densely arranged to form the low temperature region, so that the heat exchanger is simpler in structure than the conventional heat fans. This is good and the heat recovery rate of a hot air blower is large, and the heat utilization rate in a greenhouse can be raised more.
