Description

온풍난방기에 장착되는 폐열회수장치{WASTE HEAT RECOVERY APPARATUS FOR HOT AIR SUPPLY BOIER}WASTE HEAT RECOVERY APPARATUS FOR HOT AIR SUPPLY BOIER}

본 고안은 온풍난방기에 장착되는 폐열회수장치로서, 더욱 자세히는 온풍난방기의 난방보일러에서 발생되어 폐기되는 고온의 배기가스와 잉여열을 재활용하여 외부에서 흡입된 공기를 폐열로 열교환하여 고온으로 변환된 온풍을 비닐하우스 등 시설물의 실내 난방으로 활용하여 에너지효율을 제고시켜서 연비를 절약하여 경제적이고 안전한 폐열회수장치를 제공함을 목적으로 한다.The present invention is a waste heat recovery device mounted on a warm air heater, and more specifically, the high temperature exhaust gas and surplus heat generated by the heating boiler of the warm air heater are recycled, and the air sucked from the outside is converted into high temperature by heat exchange with the waste heat. It aims to provide economical and safe waste heat recovery system by saving the fuel efficiency by improving the energy efficiency by utilizing the warm air as indoor heating of facilities such as plastic houses.

종래 시설내로 온풍을 보내서 실내 온도를 높이는 온풍난방장치는 난방기에서 연소되고 배출되는 배기가스와 잉여열로 인하여 열손실이 많고 고온이기 때문에 화재나 사용자의 부주의에 의한 안전상의 문제가 있었고 이와 같은 문제점을 해소하기 위하여 개선한 것으로서 보일러의 연통에서 배출되는 배기가스를 이용하여 물을 덥혀서 온수로 사용하는 배기열 회수식이나 별도로 버너 등 가열수단을 구비하여 가열하여 사용하는 배기재연소형도 있으나 이들은 복잡한 구조로 인하여 설치가 힘들고 경제성이 없었으며, 더구나 온풍난방 용도로 사용되는 경우에도 장치가 크고 설치가 복잡해서 경제성 면에서 문제점이 있었다.The hot air heating device that sends the warm air into the facility to increase the room temperature has a lot of heat loss due to the exhaust gas and excess heat that is combusted and discharged from the heater, and because of the high temperature, there is a safety problem due to fire or carelessness of the user. In order to solve this problem, the exhaust heat recovery type used to heat the water by using the exhaust gas discharged from the boiler's flue is used as hot water or the exhaust reburn type which is heated by using a heating means such as a burner. Due to the difficult installation and economic feasibility, moreover, even when used for warm air heating, the device was large and complicated to install, which caused problems in terms of economy.

본 고안은 이와 같은 문제점을 해결하기 위하여 안출한 것으로서, 온풍난방기의 버너로부터 분사된 화염이 연소실에서 연소되어 배출되는 배기가스와 잉여열을 재활용하기 위하여 본 고안의 폐열회수기를 온풍난방기의 배기가스 토출구와 직결하고 송풍기로 페열회수기 본체내로 외부공기를 흡입하여 배기가스의 폐열로 열교환 파이프가 가열되어 온풍화되고 식혀진 공기를 본체의 양측의 배출관으로 배출되게 하였으며, 또한 폐열회수기 본체의 저부를 밀도가 조밀하게 통공이 뚫린 다공판으로 형성하므로서 송풍기를 송풍구와 흡입구를 바꿔서 설치하고 흡인모드로 전환하여 흡인력에 의하여 다공판으로 외부공기가 흡입되면 열교환파이프와 공기의 직접 접촉면적이 넓어지고 공기저항이 크게 감소되어서 열전도가 빨라지게 하고 가열된 공기는 별도의 토출구가 없이도 공기흡입구로 분사되게 하므로서 열교환효율을 극대화시키고 조립이 간편하며 작은 크기의 폐열회수기로 경제적인 폐열회수를 가능하게 하였다.The present invention has been devised to solve such a problem, and the waste heat recovery device of the present invention is a waste gas discharge port of the hot air heater in order to recycle the exhaust gas and excess heat discharged by the flame injected from the burner of the hot air heater in the combustion chamber. And the outside air is sucked into the waste heat recovery body by the blower, and the heat exchange pipe is heated by the waste heat of exhaust gas so that the warmed and cooled air is discharged to the discharge pipes on both sides of the body. Since the blower is formed into a perforated plate with densely perforated holes, the blower can be installed by changing the blower and the intake port, and then switched to the suction mode. Greatly reduced, which leads to faster heat conduction and heated air By discharging to the air inlet without a separate discharge port, the heat exchange efficiency is maximized, the assembly is simple and economical waste heat recovery is possible with a small size of the waste heat recovery device.

본 고안의 구성을 첨부 도면에 의하여 상세하게 설명하면 다음과 같다.Referring to the configuration of the subject innovation in detail as follows.

본 고안은 횡장의 사각형 본체(1)의 상부와 저부에 외부공기 흡입구(2)와 온풍토출구(7)를 형성하여 흡입구(2)에는 설치 위치를 반대 방향으로 변경하여 배출기능을 겸할 수 있는 송풍기(3)를 착설하고 본체(1) 내측으로 열교환 파이프(4)를 다수 횡설하여 양단이 배기기스 진입구(5)와 배기가스 토출구(6)가 형성되는 구성이다.The present invention forms an external air inlet (2) and a hot air outlet (7) in the upper and bottom of the rectangular body (1) of the horizontal section, the blower that can serve as a discharge function by changing the installation position in the opposite direction to the inlet (2) (3) is installed, and many heat exchange pipes 4 are laid out inside the main body 1, and the exhaust gas inlet 5 and the exhaust gas discharge port 6 are formed in both ends.

본 고안의 실시예를 구체적으로 첨부 도면에 의하여 기술하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

통상의 온풍난방기(10)가 가동되어 버너(11)에서 토출된 화염이 열교환실(13)에서 열교환작용을 마친 후 고온의 배기가스 및 잉여열이 배기가스 토출구(12)로 배출되고 온풍난방기(10)의 배기가스 토출구(12)와 연통된 폐열회수장치의 배기가스 진입구(5)로 배기가스가 흡입되어 본체(1)에 횡설된 다수 개의 열교환파이프(4)를 가열하게 되며 송풍기(3)로 흡입된 외부공기는 250-260℃의 고온에서 열풍화되고 송풍기의 공기순환으로 60℃의 저온으로 변환되어 온풍화되어서 온풍 토출구(7)로 토출되므로서 별도의 열원이 없이도 열손실 없이 비닐하우스나 축사 등의 실내를 난방시키게 된다.After the normal hot air heater 10 is operated and the flame discharged from the burner 11 completes the heat exchange operation in the heat exchange chamber 13, hot exhaust gas and excess heat are discharged to the exhaust gas discharge port 12, and the hot air heater ( The exhaust gas is sucked into the exhaust gas inlet port 5 of the waste heat recovery device in communication with the exhaust gas outlet port 12 of 10) to heat the plurality of heat exchange pipes 4 arranged in the main body 1 and the blower 3. The outside air sucked into is hot-aired at high temperature of 250-260 ℃, converted to low-temperature of 60 ℃ by air circulation of blower, and warmed and discharged to hot air discharge port (7), so that there is no heat loss without any heat source. It will heat the room such as a house or a barn.

또한 다른 실시예로서 폐열회수장치 본체(1)의 저부를 밀도가 조밀하게 다수의 통공(8a)이 있는 다공판(8)으로 형성하고 송풍기(3)를 흡입모드로 즉 송풍구와 흡입구를 거꾸로 전환하여 역회전시키면 송풍기의 흡인력에 의하여 다공판(8)으로 외부공기가 흡입되면 열교환파이프(4)와 공기의 직접 접촉면적이 넓어지고 공기저항이 크게 감소되어서 열전도가 빨라지고 가열된 공기는 별도의 토출구가 없이도 다시 공기흡입구(2)로 방출되게 하므로서 열교환효율을 극대화시킬 수 있다.In another embodiment, the bottom of the waste heat recovery system main body 1 is formed of a porous plate 8 having a plurality of through holes 8a with dense density, and the blower 3 is switched to the suction mode, that is, the blower and the suction ports are reversed. When the reverse rotation is performed, if the external air is sucked into the porous plate 8 by the suction force of the blower, the area of direct contact between the heat exchange pipe 4 and the air is widened and the air resistance is greatly reduced, so that the thermal conductivity is increased and the heated air is discharged separately. Without being discharged back to the air inlet (2) can maximize the heat exchange efficiency.

이와 같이 된 본 고안은 별도의 열원이 없이도 보일러에서 발생되는 고온의 배기가스와 잉여열을 재활용하여 열효율을 극대화시킬 수 있는 경제적인 장치로서 화재나 사용자의 부주의에 의한 사고를 미연에 예방할 수 있는 효과가 있다.The present invention is an economical device that can maximize the thermal efficiency by recycling the high-temperature exhaust gas and excess heat generated from the boiler without the need for a separate heat source, which can prevent the accidents caused by fire or user's carelessness. There is.
