Description

수관식 증기 및 급탕 보일러{Steam and warm water boiler}Steam and warm water boilers

본 발명은 수관식 증기보일러에 관한 것으로, 보다 상세하게는 보일러 내부에 관수헤드와 증기헤드를 상/하 수평으로 배치하고, 이 관수헤드와 증기헤드는 상/하로 배열 설치되는 다수의 수관으로 연결하며, 관수헤드의 내부에는 온수공급용 열교환기를 설치함으로써, 관수헤드내부의 고온의 관수로 열교환기내부의 온수를 가열하여, 하나의 보일러로써 증기와 온수를 동시에 공급할 수 있도록 하는 수관식 증기 및 급탕 보일러에 관한 것이다.The present invention relates to a water pipe steam boiler, and more particularly, the watering head and the steam head is arranged horizontally up and down inside the boiler, the water head and the steam head is connected to a plurality of water pipes arranged up and down arranged The inside of the irrigation head is provided with a heat exchanger for hot water supply to heat the hot water in the heat exchanger with a high temperature irrigation in the irrigation head, so that the steam and hot water can be supplied simultaneously with one boiler. It's about a boiler.

일반적으로 목욕탕과 같이 증기 및 온수를 사용하는 곳에서는 증기를 공급하기 위한 증기보일러 및 온수를 공급하기 위한 온수보일러가 필요하며, 종래에는 이들을 각각 독립적으로 운전하였으므로, 연료비가 많이 들고, 유지 및 관리가 어려운 문제점이 있었다.In general, where steam and hot water are used, such as a bathroom, a steam boiler for supplying steam and a hot water boiler for supplying hot water are required. There was a difficult problem.

이와 같은 문제점을 해결하기 위하여 증기보일러로부터 발생된 증기를 일부는 사우나실로 보내고, 사우나실로부터 발생되는 폐증기와 증기보일러로부터 발생된 증기중 사우나실로 보내지 않은 다른 증기를 그대로 혹은 액상으로 변환시켜 온수탱크에 설치된 열교환기로 보냄으로써, 증기보일러의 열을 이용하여 증기와 온수를 동시에 사용할 수 있도록 하는 기술이 개발되어 현재 사용되고 있다.In order to solve this problem, some of the steam generated from the steam boiler is sent to the sauna room, and the hot steam tank is converted into the liquid phase as it is or the other steam that is not sent to the sauna room among the waste steam generated from the sauna room and steam generated from the steam boiler. By sending to the heat exchanger installed in the, the technology to use the steam and hot water at the same time by using the heat of the steam boiler has been developed and currently used.

그러나 상기한 바와 같이 증기보일러를 이용하여 증기와 온수를 공급하는 시스템에서는 증기가 열교환기까지 가는 동안 관로가 외부와 열교환하므로 열손실이 많고, 관로를 이용하여 증기보일러와 열교환기를 연결하여야 하므로 설치가 복잡할 뿐 아니라, 일반적으로 목욕탕에서는 증기:온수의 비율이 20~30:70~80이므로 상기한 바와 같이 증기보일러의 가동만으로 온수를 공급할때에는 급탕의 효과가 떨어지는 문제점이 발생되었기 때문에 종래에는 여름과 같이 온수의 사용량이 떨어지더라도 온수보일러 및 증기보일러를 모두 가동하여야 하므로 연료소비가 많은 문제점이 있을 뿐 아니라, 증기보일러와 온수보일러를 모두설치하여야 하므로 공간과 운영 및 유지비가 많이 소모되는 문제점이 있었다.However, in the system for supplying steam and hot water using the steam boiler as described above, since the pipe heat exchanges with the outside while the steam goes to the heat exchanger, there is a lot of heat loss, and it is necessary to connect the steam boiler and the heat exchanger using the pipe. In addition, since the ratio of steam: hot water is generally 20-30: 70-80 in the bathroom, the effect of the hot water supply decreases when supplying hot water only by operating the steam boiler as described above. Likewise, even when the amount of hot water drops, both the hot water boiler and the steam boiler have to be operated, and therefore, fuel consumption is not only a problem, but both the steam boiler and the hot water boiler need to be installed, which causes a lot of space, operation and maintenance costs.

상기한 바와 같은 문제점을 해결하기 위한 본 발명의 목적은 보일러 내부에 관수헤드와 증기헤드를 상/하 수평으로 배치하고, 이 관수헤드와 증기헤드는 상하로 설치되는 다수의 수관으로 연결하며, 관수헤드의 내부에는 온수공급용 열교환기를 설치함으로써, 관수헤드내부의 고온의 관수로 열교환기내부의 온수를 가열하여, 하나의 보일러로써 증기와 온수를 동시에 공급할 수 있도록 하는 수관식 증기 및 급탕 보일러를 제공하는데 있다.An object of the present invention for solving the problems as described above is to place the irrigation head and the steam head horizontally in the boiler, the water head and the steam head is connected to a plurality of water pipes installed up and down, watering The inside of the head is provided with a hot water supply heat exchanger to heat the hot water inside the heat exchanger with a high temperature irrigation in the irrigation head, thereby providing a water pipe steam and hot water boiler that can simultaneously supply steam and hot water as one boiler.

On the other hand, both sides of the steam head 30 and the watering head 20 has a plurality of fire-resistant and heat-insulating jackets having the same shape as the shape of the steam head 30 and watering head 20 in the upper and lower portions ( 60 and 70 are integrally coupled to each other in contact with the steam head 30 and the watering head 20 of the main body so that the respective shapes coincide with each other. In this case, the inner empty space of the jacket 60 or 70 is a predetermined amount of water. To perform the function of the storage chamber (62, 72) to store the one of the plurality of jackets (60, 70) of the jacket 60, the heat exchange tube 82 is the projection 22 of the irrigation head (20) It is installed through the heat exchanger 80 to be installed inside.

한편, 상기한 구성에서 열교환기(80)는 해당업자라면 다수의 방법으로 실시 가능하겠으나, 본 발명에서는 U형 4패스식 열교환기(80)를 예로써 도 1c및 도 1d를 참조하여 살펴보면, 격판(83)에 의하여 유입관(84a)이 설치된 유입실(84)과 유출관(85a)이 설치된 유출실(85)및 중계실(86)로 삼분된 열교환기 헤드(87)와, 다수의 통공(88a)이 형성되어 상기 열교환기 헤드(87)의 일면에 밀착설치되는 차단관판(88)과, U형으로 형성되어 상기 차단관판(88)의 통공(88a)에 양종단이 설치되는 열교환용관(82)으로 구성된다.On the other hand, the heat exchanger 80 in the above configuration can be implemented in a number of ways if the relevant company, in the present invention with reference to the U-type 4-pass type heat exchanger 80 with reference to Figure 1c and Figure 1d, diaphragm The heat exchanger head 87 divided into the inflow chamber 84 in which the inflow pipe 84a is provided by the inflow pipe 84a, the outflow chamber 85 in which the outflow pipe 85a is installed, and the relay chamber 86, and many through-holes ( 88a) is formed to close the tube tube 88 is installed in close contact with one surface of the heat exchanger head 87, the heat exchange tube formed in the U-shaped both ends of the through-hole 88a of the barrier tube plate 88 ( 82).

이와 같이 구성된 본 발명에 따른 수관식 증기 및 급탕 보일러의 사용예를 하기에서 살펴본다.An example of the use of the water pipe steam and hot water boiler according to the present invention configured as described above will be described below.

버너(16)를 통하여 연소실(18)내로 화염이 분사되면, 이 화염으로부터 연소실(18) 내부에 발생된 고온의 연소가스는 복수개의 전열핀(52)(54)과 커버(10) 사이를 상하 지그재그식으로 통과한 후 집연실(12)에 모여 연도(14)로 배출되고, 관수유입구(74)를 통하여 하부에 수평형으로 배치된 관수헤드(20)로 유입된 관수는 화염 및 고온의 연소가스에 의하여 가열되면서 증기가 되어 수관(40)을 통하여 증기헤드(30)로 모이게 되고, 증기헤드(30)로 모인 증기는 수실(62, 72)로부터 유입된 증기와 함께 증기출구(19)를 통해서 외부로 배출된다.When the flame is injected into the combustion chamber 18 through the burner 16, the high temperature combustion gas generated in the combustion chamber 18 from the flame passes between the plurality of heat transfer fins 52, 54 and the cover 10 up and down. After passing in a zigzag manner, the water is collected in the collecting chamber 12 and discharged into the flue 14, and the water flowing into the irrigation head 20 arranged horizontally in the lower portion through the irrigation inlet 74 is flame and high temperature combustion. The steam is heated by the gas to be collected in the steam head 30 through the water pipe (40), the steam collected in the steam head 30 together with the steam introduced from the water chamber (62, 72) to the steam outlet (19) Through the outside.

이때, 순환펌프(90)에 의하여 온수저장탱크(92)로부터 강제로 열교환기(80)의 유입실(84)로 들어온 물은 열교환용관(82)을 거쳐서 중계실(86)로 유입되고 이와 같이 중계실(86)로 유입된 물은 다시 열교환용관(82)을 거쳐 유출실(85)로 흐르므로, 유입실(84)로 유입된 물이 유출실(85)로 가는 도중에 관수헤드(20)내부의 고온수와 열교환하므로, 유출구(85a)로는 고온의 온수가 배출된다.At this time, the water entering the inlet chamber 84 of the heat exchanger 80 by force from the hot water storage tank 92 by the circulation pump 90 is introduced into the relay room 86 via the heat exchange tube 82 and thus the relay room Since the water introduced into the 86 flows again through the heat exchange tube 82 to the outflow chamber 85, the water introduced into the inflow chamber 84 flows into the outflow chamber 85 in the watering head 20. Since it exchanges heat with hot water, hot water of high temperature is discharged to the outlet port 85a.

그리고, 도면중 미설명부호 95a및 95b는 체크밸브로써, 온수저장탱크 내부의 물이 특정온도, 예를 들면 80℃ 이상이 되어 순환펌프(90)가 멈출경우 열교환기(80)내부의 증기가 온수저장탱크(92)내부로 역류하는 것을 방지하기 위한 것이다.In the drawings, reference numerals 95a and 95b are check valves, and when the water inside the hot water storage tank reaches a specific temperature, for example, 80 ° C. or higher, and the circulation pump 90 stops, the steam inside the heat exchanger 80 It is to prevent the back flow into the hot water storage tank 92.

따라서, 본 발명에 의하면 하나의 보일러를 가동하여 충분한 증기와 온수를 공급받을 수 있게 된다.Therefore, according to the present invention, one boiler can be operated to receive sufficient steam and hot water.

상기한 바와 같이 구성되는 수관식 증기 및 급탕 보일러에 의하면, 관수헤드내부에 열교환기의 열교환용관이 설치되어 하나의 보일러 가동만으로 종래의 온수보일러와 증기보일러를 동시에 가동한 만큼의 증기와 온수를 공급받을 수 있게되므로, 운영비와 설치공간의 소모가 작으며, 하나의 보일러만 설치하면 되므로 설치공정이 간단하고, 유지 관리가 용이한 효과가 있으며, 보일러가 수평형이므로 설치하고자 하는 공간의 반입구폭에 제한을 덜 받게 되는 효과가 있다.According to the water pipe steam and hot water boiler configured as described above, the heat exchanger tube of the heat exchanger is installed inside the watering head to supply the steam and hot water as long as the conventional hot water boiler and steam boiler are operated simultaneously with only one boiler operation. Because it can be received, the operating cost and the consumption of installation space are small, and only one boiler needs to be installed, so the installation process is simple, the maintenance is easy, and the boiler is horizontal, so the opening width of the space to be installed There is less effect on the effect.
