(3) are arranged on the inner circumferential surface of the heat exchange chamber (2) in which the air inlets (2a) and the waste heat recovery holes (2b) are symmetrically arranged so as to pass through the plates (4) and (4a) side by side at a dense interval of saturation.

Description
종래 보일러의 폐열을 회수하는 장치는 연통의 외주면에 환상의 방열핀을 형성하고 그 주위에 커버를 형성하여 커버내에 외부 공기를 순환시키어 연통에서 방열되는 열을 회수하여 보일러 버어너의 송풍기에 순환 공급하게 되어 있다.Conventionally, a device for recovering waste heat of a boiler forms an annular heat dissipation fin on an outer circumferential surface of a communication tube and forms a cover around it to circulate external air in the cover to recover heat radiated from the communication and circulate and supply it to a blower of a boiler burner. It is.
이러한 구성의 폐열회수장치는 연통을 이용한 것으로 배연저항이 작은 장점은 있으나 연통의 주면에서만 열교환작용이 이루어지기 때문에 방열면적이 적고 연통의 내부측의 배연가스의 열은 회수되지 않고 배기되어 연통의 폐열 회수율이 높지 못한 미비점이 있었다.The waste heat recovery device having such a configuration uses a communication, which has a small flue resistance. However, since the heat exchange action is performed only on the main surface of the communication, the heat dissipation area is small and the heat of the flue gas inside the communication is not recovered but is exhausted to exhaust the waste heat of the communication. There was a defect that the recovery rate was not high.
본 고안은 종래의 이러한 문제점을 시정하기 위하여, 원통형으로 된 폐열회수기의 기체 내부의 열교환실에 다수의 환상 방열핀이 조밀하게 형성된 열교환관을 포화상태의 조밀한 간격으로 나란히 상하 격판으로 관통되게 배치하고 기체의 상하 양단부에는 연통의 결합구를 형성하여 각각 연통을 관접할 수 있게 하며, 열교환실의 내주벽에는 복수개의 유도편을 대칭으로 형성하여 폐열회수장치를 구성한다.The present invention is to solve this problem of the prior art, the heat exchanger tube formed with a plurality of annular heat-dissipating fins densely arranged in the heat exchange chamber inside the gas of the cylindrical waste heat recovery machine is arranged to penetrate the upper and lower plates side by side at a dense interval of saturation state The upper and lower ends of the gas form a coupling coupling hole so that each can be connected to each other, and a plurality of guide pieces are formed symmetrically on the inner circumferential wall of the heat exchange chamber to form a waste heat recovery device.
따라서 공기유입구에서 폐열회수구로 통과하는 송풍된 공기가 공기유도편의 유도 작용에 의하여 모든 열교환관과 균일하게 접촉되는 동시 열교환실의 단위 공간면적 당 방열핀의 방열면적이 매우 크게 증대되어 방열핀에 의하여 용이하게 열교환작용이 일어나 종래의 것에 비하여 연통으로 배출되는 폐열 회수율을 보다 높힐 수 있게 안출한 것이다.Therefore, the heat dissipation area of the heat dissipation fin per unit space area of the simultaneous heat exchange chamber, in which the blown air passing from the air inlet to the waste heat recovery port is uniformly contacted with all the heat exchange tubes by the induction action of the air induction piece, is greatly increased, which makes it easy As a result of the heat exchange action, it is possible to increase the recovery rate of waste heat discharged through the communication as compared with the conventional one.

연통의 단면적보다 약간 내부 지름이 크게 된 원통형의 폐혈 회수기의 기체(1) 내부의 열교환실(2)에 다수의 환상 방열핀(3a)이 조밀하게 형성된 다수의 열교환관(3)을 포화상태의 조밀한 간격으로 상하의 격판(4)(4a)관통되게 나란히 배치하고 격판(4)(4a)의 외측의 기체(1)에는 연통 결합구(5)(5a)를 형성하여 통상의 연통(6)(6a)을 관접할 수 있게 하며, 기체(1)의 상하 대칭방향으로 공기유입구(2a)와 폐열 회수구(2b)를 형성하며 열교환실(2)의 내주면에는 복수개의 공기유도편 (2c)을 중심방향의 대칭으로 형성하여, 외부공기가 교환실내부의 모든 열교환관과 균일하게 접촉하면서 열교환작용에 의하여 연통의 배기가스의 폐열 회수율을 보다 높힐 수 있게 구성하여 된 것이다.In the heat exchange chamber 2 inside the gas 1 of the cylindrical pulmonary blood collecting device whose inner diameter is slightly larger than the cross-sectional area of the communication, a plurality of heat exchange tubes 3 having densely formed annular heat radiating fins 3a are saturated. Arranged side by side so as to pass through the upper and lower diaphragms (4) and (4a) at an interval, and form communication coupling holes (5) and (5a) in the base (1) outside the diaphragms (4) and (4a) so as to communicate normally (6) 6a), the air inlet 2a and the waste heat recovery port 2b are formed in the vertically symmetrical direction of the gas 1, and a plurality of air induction pieces 2c are formed on the inner circumferential surface of the heat exchange chamber 2; Formed symmetrically in the center direction, the outside air is made to be in contact with all the heat exchange tubes inside the exchange chamber uniformly to increase the waste heat recovery rate of the exhaust gas of the communication by heat exchange action.
도면중 미설명 부호 7은 모터 송풍기이다.In the figure, reference numeral 7 denotes a motor blower.
이와 같이 된 본 고안은 도2 에 표시된 바와 같이 폐열회수기의 기체(1)의 연통 결합구(4)(4a)를 이용하여, 보일러에 가까운 위치에서 연통(6)(6a)의 단부가 격판(4)(4a)에 밀착되게 관접하고 공기유입구(2a)에는 모터 송풍기(7)를 관접하며 폐열회수구(2a)에는 도시되지 않은 도관을 통하여 실내에 유도하거나 보일러의 급기관에 연결하여 사용한다.In the present invention, as shown in FIG. 2, the communication coupling holes 4 and 4a of the gas 1 of the waste heat recovery machine are used, and the ends of the communication 6 and 6a are close to the boiler at a position close to the boiler. 4) In close contact with (4a), the air inlet (2a) is connected to the motor blower (7) and the waste heat recovery (2a) through the conduit not shown in the room or connected to the supply pipe of the boiler is used. .
보일러의 연소가스는 연통(6)(6a)으로 배기되는 도중에 기체(1)의 열교환실 (2)에 조밀하게 배치된 각 열교환관(3)을 통하여 분산 배기되며, 이때 모터 송풍기(7)에 의하여 송풍된 공기는 공기유입구(2a)를 통하여 열교환실(2)내부로 유입되며 유입된 공기는 유도편(2c)에 의하여 열교환실(2)의 중심부를 비롯하여 사방으로 공기의 흐름이 집산(集散)되면서 모든 열교환관(3) 및 방열핀(3a)과 균잃게 접촉되면서 열교환 작용이 일어난다.The combustion gas of the boiler is distributed and exhausted through each heat exchange tube 3 which is densely arranged in the heat exchange chamber 2 of the gas 1 while being exhausted into the communication 6, 6 a, and at this time, to the motor blower 7. The air blown by the air flows into the heat exchange chamber (2) through the air inlet (2a), and the flow of air is collected by the guide piece (2c) and the flow of air in all directions including the center of the heat exchange chamber (2). The heat exchange action takes place while being in contact with the heat exchange tube 3 and the heat dissipation fins 3a.
따라서 연통으로 배기되는 연소가스가 작은 내경의 열교환관(3)으로 통과하는 중에 열교환작용에 의하여 폐열이 회수되고 회수된 폐열은 폐열회수구(2b)를 통하여 실내에 공급되어 난방을 보조하거나 보일러의 버어너측에 송풍되어 버어너의 열효율을 높힐 수 있게 된다.Therefore, waste heat is recovered by heat exchange while the combustion gas exhausted through the communication passes through the heat exchange tube 3 having a small inner diameter, and the waste heat recovered is supplied to the room through the waste heat recovery port 2b to assist heating or It is blown to the burner side to increase the thermal efficiency of the burner.
본 고안 타이트한 구조로 견고하고 간단하여, 각종 보일러의 배기열을 회수하는 폐열회수기로 사용하는데 적합하고 가동부분이 없으므로 마모나 고장의 우려가 없으며, 조밀하게 배치된 열교환관의 방열핀에 의하여 열교환실의 공간 단위면적당 방열면적이 훨신 증가되어 종래의 것에 비하여 연통의 폐열 회수율이 보다 높으며, 폐열을 이용한 난방 보조나 보일러의 버어너의 온풍공급하는데 보다 유용하게 사용할 수 있는 효과가 있다.The tight and simple structure of the present invention makes it suitable for use as a waste heat recoverer for recovering exhaust heat from various boilers, and there is no fear of wear or failure since there are no moving parts. Since the heat dissipation area per unit area is much increased, the waste heat recovery rate of the communication is higher than that of the conventional one, and there is an effect that it can be more usefully used for heating assistance using waste heat or hot air supply of the burner of the boiler.
