Description

Waste recycling machine {The recycling device of waste heat}

본 고안은 가정용 보일러장치에 설치되어 보일러 연소시 배기가스의 형태로 대기로 방출되는 폐열을 회수하여 활용하기 위한 폐열회수기에 관한 것으로서, 보다 상세하게는 청소용퇴수구를 형성하여 폐열방출기의 내부 청소를 가능하게하며, 폐열방출부에 챔버를 구비하여 챔버내로 유입되는 고온의 배기가스가 지체되도록 하여 충분한 열교환이 이루어지게 한 폐열회수기에 관한 것이다.The present invention relates to a waste heat recovery device installed in a domestic boiler device for recovering and utilizing waste heat discharged to the atmosphere in the form of exhaust gas when the boiler burns, and more specifically, to clean the interior of the waste heat discharger by forming a cleaning discharge port. The present invention relates to a waste heat recoverer having a chamber for discharging waste heat and allowing a high temperature exhaust gas introduced into the chamber to be delayed to allow sufficient heat exchange.

종래의 폐열회수기는 배기가스가 폐열방출기의 내부를 통과하는 과정에서 검댕을 생성시켜 폐열방출기의 내부벽을 오염시킴으로서 열교환효율을 저하시키는데도 불구하고 폐열방출기의 내부를 청소할 수 없었고, 폐열방출기로 유입된 고온의 배기가스가 지체될 수 있는 구조의 열교환관이 사용되지 않아 폐열회수기를 빨리 통과하여 외부로 방출됨으로써 충분한 열교환이 이루어지지 않는 문제점이 있었다.The conventional waste heat recovery machine cannot clean the inside of the waste heat radiator even though the exhaust gas passes through the inside of the waste heat radiator to contaminate the inner wall of the waste heat radiator to reduce the heat exchange efficiency by contaminating the inner wall of the waste heat radiator. Since a heat exchanger tube having a structure in which high temperature exhaust gas is delayed is not used, there is a problem that sufficient heat exchange is not achieved because the heat exchanger is quickly discharged to the outside.

본 고안의 폐열회수기는 이와같은 문제점을 해소하기 위한 것으로, 폐열회수기 내부의 청소가 가능하며, 열교환이 충분히 이루어지게 하는데 그 목적이 있다.Waste heat recovery device of the present invention is to solve such a problem, it is possible to clean the inside of the waste heat recovery, and its purpose is to make a sufficient heat exchange.

이러한 목적을 달성하기 위하여 본 고안의 폐열회수기는 수입구, 수출구가 구비되어 있는 원통형의 폐열흡수부 내부에 배기가스입구, 배기가스출구, 청소용퇴수구, 챔버, 열교환관이 구비되어 있는 폐열방출부가 삽입되어 있는 것에 그 특징이 있다.In order to achieve this purpose, the waste heat recovery device of the present invention has a waste heat discharge which is provided with an exhaust gas inlet, an exhaust gas outlet, a cleaning discharge port, a chamber, and a heat exchanger tube in a cylindrical waste heat absorbing part provided with an import port and an export port.

본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention is as follows.

본 고안의 보일러장치용 폐열회수기(1)는 도 4와 같이 배기가스입구(5)와 보일러장치의 연도(15)을 연결하여 배기가스가 폐열방출부(3) 내부로 유입되도록 하고, 배기가스출구(6)를 개방하여 배기가스가 대기로 방출되게 하며, 수입구(7)와 물탱크(12)를 연결하여 물이 폐열흡수부(2) 내부로 유입되도록 하고, 수출구(8)와 온수급수구(16)를 연결하여 물이 보일러(13)로 유입되도록 설치된다.Waste heat recovery device 1 for the boiler device of the present invention is connected to the exhaust gas inlet 5 and the flue 15 of the boiler device as shown in Figure 4 so that the exhaust gas flows into the waste heat discharge unit 3, exhaust gas Open the outlet 6 to discharge the exhaust gas into the atmosphere, connect the import port (7) and the water tank (12) so that the water flows into the waste heat absorption unit (2), and the export port (8) and By connecting the hot water supply port 16 is installed so that water is introduced into the boiler (13).

보일러(13)를 가동할 경우 보일러(13)에서 발생된 고온의 배기가스는 배기가스입구(5), 챔버(4a), 열교환관(11a), 챔버(4b), 열교환관(11b), 챔버(4c), 배기가스출구(6)의 순서로 이동하면서 폐열흡수부(2)쪽으로 폐열을 방출하여 저온의 배기가스가 되어 대기로 방출되고, 물탱크(12)에서 공급되는 상온의 물은 수입구(7)에서 수출구(8)로 이동하면서 폐열방출부(3)에서 방출되는 폐열을 흡수하여 예열되어 비중차에 의해 유동이 발생함으로써 자연스럽게 수출구(8)를 거쳐 보일러(13)에 구비되어 있는 온수급수구(16)로 유입된다.When the boiler 13 is operated, the high temperature exhaust gas generated by the boiler 13 is exhaust gas inlet 5, chamber 4a, heat exchanger tube 11a, chamber 4b, heat exchanger tube 11b, chamber. (4c), the waste heat is discharged toward the waste heat absorbing portion 2 while moving in the order of the exhaust gas outlet 6, becomes a low-temperature exhaust gas, and is released into the atmosphere, and the water at room temperature supplied from the water tank 12 Moving from the inlet (7) to the export port (8) absorbs the waste heat discharged from the waste heat dissipation unit (3) is preheated, the flow is generated by the specific gravity difference is provided in the boiler 13 through the export port (8) naturally It is introduced into the hot water supply opening (16).

한편, 챔버(4a)(4b)(4c)로 유입된 배기가스는 배기가스입구(5)와 열교환관(11a)(11b)(11c) 보다 단면적과 용적이 크게 형성되어 있으므로 배기가스의 대부분이 바로 빠져나가지 못하고 챔버(4a)(4b)(4c) 내부에서 지체되어 충분한 열교환이 일어난다.On the other hand, the exhaust gas flowing into the chambers 4a, 4b and 4c has a larger cross-sectional area and volume than the exhaust gas inlet 5 and the heat exchange tubes 11a, 11b and 11c. It does not exit immediately and is delayed inside the chambers 4a, 4b and 4c, resulting in sufficient heat exchange.

보일러(13)를 장기간 가동하여 배기가스에 포함되어 있는 오염물질이 폐열방출부(3)의 내벽에 달라붙어 열교환효율이 저하될 경우에는 연도(15)와 폐열회수기(1)를 분리하고 퇴수밸브(10)를 개방한 상태에서 배기가스출구(6)에 물을 넣어주면 오염물질이 씻겨 내려서 청소용퇴수구(9)로 배출된다.When the boiler 13 is operated for a long time and contaminants contained in the exhaust gas stick to the inner wall of the waste heat discharge unit 3, and the heat exchange efficiency decreases, the flue 15 and the waste heat recovery unit 1 are separated and the discharge valve If water is put in the exhaust gas outlet 6 in the state of opening 10, contaminants are washed off and discharged to the cleaning drain 9.

본 고안의 폐열회수기는 청소용퇴수구와 퇴수밸브를 구비하여 폐열방출부 내벽에 달라붙게 되는 오염물질을 물청소후 간단하게 배출시키게 되어 있어 폐열회수기의 내부를 청소가능하게 하며, 배기가스가 지체되도록 하는 큰 용적의 챔버를 폐열방출부 내부에 단계적으로 구비하여 충분한 열교환이 이루어지게 하는 효과가 있다. 또한 챔버와 열교환파이프 내부를 배기가스가 통과하면서 통상의 소음기와 같은 원리에 의해 보일러 내부의 연소소음이 줄어드는 효과가 있다.The waste heat recovery device of the present invention is provided with a cleaning discharge port and a discharge valve to easily discharge contaminants that adhere to the inner wall of the waste heat discharge unit after cleaning, so that the inside of the waste heat recovery device can be cleaned and the exhaust gas is delayed. It is effective to provide a sufficient heat exchange step by providing a large volume chamber to the waste heat discharge unit in stages. In addition, as the exhaust gas passes through the chamber and the heat exchange pipe, the combustion noise inside the boiler is reduced by the same principle as a conventional silencer.
