스팀보일러의 급수장치{Device of Supplying a Steam Boiler}Device of Supplying a Steam Boiler
본 고안은 물을 가열하여 난방을 실시하는 스팀보일러에 관한 것으로서, 좀더 구체적으로는 고가의 콤프레셔를 설치하지 않고도 응축수 모음탱크내의 물을 보일러의 내부로 급수할 수 있도록 하는 스팀보일러의 급수장치에 관한 것이다.The present invention relates to a steam boiler that heats water and heats it, and more particularly, to a water supply system of a steam boiler which can supply water in a condensate collection tank to a boiler without installing an expensive compressor. will be.
일반적으로 물을 가열함에 따라 얻어지는 고압의 스팀은 세탁소, 봉제공장, 취사장 등 여러 분야에서 널리 사용되고 있는데, 이러한 스팀은 통상 스팀보일러에 의해 얻어진다.In general, high-pressure steam obtained by heating water is widely used in various fields such as a laundry, a sewing factory, a kitchen, and the like, and such steam is usually obtained by a steam boiler.
도 1은 종래 장치의 구성을 나타낸 종단면도로서, 응축수 모음탱크(2)가 보일러(1)의 일측에 나란히 설치되어 있고 보일러(1)의 일측에는 보일러의 내부에 위치하는 응축수(3)의 수위를 감지하는 자동수위 감지센서(4)가 설치되어 있다.1 is a longitudinal cross-sectional view showing the configuration of a conventional apparatus, in which the condensate collection tank 2 is installed side by side on one side of the boiler 1 and the water level of the condensate 3 located inside the boiler on one side of the boiler 1. Automatic water level sensor (4) is installed to detect the.
상기 응축수 모음탱크(2)의 상부에 압축공기 공급관(5)이 연결되어 있고 상기 압축공기 공급관의 다른 일단에는 응축수 모음탱크(2)에 설치된 자동압력 조절스위치(6)가 설정 압력 이하임을 감지에 따라 구동하여 압축공기를 발생시키는 콤프레셔(7)가 설치되어 있다.Compressed air supply pipe (5) is connected to the upper portion of the condensate collection tank (2) and the other end of the compressed air supply pipe to detect that the automatic pressure control switch (6) installed in the condensate collection tank (2) is below the set pressure The compressor 7 which drives along and produces | generates compressed air is provided.
따라서 보일러(1)의 계속되는 가동으로 보일러에 있던 응축수(3)의 수위가 설정된 수위보다 낮아짐을 자동수위 감지센서(4)가 감지하면 응축수 공급관(8)상에 설치된 전자밸브(9)가 개방되므로 응축수 모음탱크(2)내의 응축수가 보일러(1)의 내부로 충수되는데, 이 때 응축수 모음탱크(2)의 수위가 일측에 위치된 보일러(1)의 수위보다 낮은 상태를 유지하더라도 응축수 모음탱크(2)의 상부에는 보일러(1)내의 스팀압력보다 높은 압축공기의 압력이 작용되고 있으므로 응축수 모음탱크(2)내의 응축수가 응축수 공급관(8)을 통해 보일러(1)내에 충수된다.Therefore, when the automatic water level sensor 4 detects that the water level of the condensate water 3 in the boiler is lower than the set water level due to the continuous operation of the boiler 1, the solenoid valve 9 installed on the condensate water supply pipe 8 is opened. Condensate in the condensate collection tank (2) is filled into the interior of the boiler (1), at this time, even if the water level of the condensate collection tank (2) is lower than the water level of the boiler (1) located on one side (condensate collection tank (2). Since the pressure of the compressed air higher than the steam pressure in the boiler 1 is applied to the upper part of 2), the condensed water in the condensate collection tank 2 is filled in the boiler 1 through the condensed water supply pipe 8.
상기한 동작으로 응축수 모음탱크(2)내의 응축수(3)가 보일러(1)의 내부로공급되어 자동수위 감지센서(4)가 이를 감지하면 응축수 공급관(8)상에 설치된 전자밸브(9)가 응축수 공급관(8)의 관로를 폐쇄하게 되므로 응축수의 공급이 중단된다.When the condensate (3) in the condensate collection tank (2) is supplied to the inside of the boiler (1) by the above operation and the automatic water level sensor (4) detects this, the solenoid valve (9) installed on the condensate supply pipe (8) is Since the conduit of the condensate supply pipe (8) is closed, the supply of condensate is stopped.
그러나 이러한 종래의 장치는 응축수 모음탱크내의 응축수를 보일러측에 급수하기 위해서는 반드시 응축수 모음탱크의 내부에 압력을 가하기 위한 별도의 콤프레셔를 설치하여야 되었으므로 설비비가 많이 소요되었음은 물론 그에 따라 유지 관리비가 많이 소요되는 문제점이 있었다.However, in order to supply condensate in the condensate collection tank to the boiler side, such a conventional apparatus has to install a separate compressor for pressurizing the inside of the condensate collection tank. There was a problem.
본 고안은 이와 같은 종래의 문제점을 해결하기 위해 안출한 것으로서, 그 구조를 개선하여 고가의 콤프레셔를 사용하지 않고도 응축수 모음탱크내에 있던 응축수를 보일러측으로 자동 급수할 수 있도록 하는데 그 목적이 있다.The present invention has been made to solve such a conventional problem, and the object of the present invention is to improve the structure and to automatically supply the condensate in the condensate collection tank to the boiler side without using an expensive compressor.
상기 목적을 달성하기 위한 본 고안의 형태에 따르면, 보일러의 일측에 응축수 모음탱크를 설치하여 상기 응축수 모음탱크 내의 응축수를 펌프의 구동에 따라 보일러의 내부로 급수하도록 구성된 스팀보일러의 급수장치에 있어서, 응축수 공급관상에 제1밸브를 설치하여 상기 응축수 공급관을 연결관에 연결하고 펌프의 토출측과 보일러사이에 설치된 급수관상에는 제2밸브를 설치함과 동시에 제2밸브의 후단과 응축수 모음탱크사이에는 제3밸브를 구비한 응축수 회수관을 연결하며 스팀관과 응축수 모음탱크상부에는 체크밸브가 구비된 균압관을 연결하여서 된 것을 특징으로 하는 스팀보일러의 급수장치가 제공된다.According to a form of the present invention for achieving the above object, in the water supply unit of the steam boiler is configured to provide a condensate collection tank on one side of the boiler to supply the condensed water in the condensate collection tank to the inside of the boiler according to the driving of the pump, A first valve is installed on the condensate supply pipe to connect the condensate supply pipe to the connection pipe, and a second valve is installed on the water supply pipe installed between the discharge side of the pump and the boiler, and a third valve is connected between the rear end of the second valve and the condensate collection tank.

먼저, 보일러(1)의 내부에 관수가 급수되어 수위감지스위치(4)가 이를 감지하면 이를 가열하게 되므로 발생된 스팀은 스팀관(18)을 통해 열교환기(21)측으로 공급되어 여러 용도로 사용된다.First, since water is supplied to the inside of the boiler 1 and the water level detecting switch 4 detects this, the steam is heated so that the generated steam is supplied to the heat exchanger 21 through the steam pipe 18 to be used for various purposes. do.
이와 같이 스팀이 열교환기(21)에서 열교환하므로 인해 응축되면 증기트랩(22)에서 응축수만을 응축수 회수탱크(23)로 회수하게 되는데, 상기 응축수 회수탱크(23)내의 감지수단(압력스위치 또는 플로트 스위치)(24)이 일정량 이상의 응축수를 감지하면 제어부(도시는 생략함)에 의해 펌프(13)가 가동하게 응축수 회수탱크(23) 내의 응축수(3)를 응축수 모음탱크(2)측으로 충수시키게 된다.When the steam condenses due to heat exchange in the heat exchanger 21 as described above, only the condensed water is recovered from the steam trap 22 to the condensate recovery tank 23, and the sensing means (pressure switch or float switch) in the condensate recovery tank 23. When 24) detects a certain amount of condensate, the control unit (not shown) causes the pump 13 to operate to replenish the condensate 3 in the condensate return tank 23 toward the condensate collection tank 2.
이 때, 급수관(15) 및 응축수 공급관(11)상에 설치된 제1, 2밸브(12)(14)는오프(off)되어 폐쇄된 상태를 유지하고 응축수 회수관(17)상에 설치된 제3밸브(16)는 온(on)되어 개방된 상태를 유지하게 되므로 응축수 회수탱크(23) 내의 응축수가 응축수 회수관(17)을 통해 응축수 모음탱크(2)측으로 충수된다.At this time, the first and second valves 12 and 14 provided on the water supply pipe 15 and the condensed water supply pipe 11 are turned off to maintain a closed state, and the third and third valves installed on the condensed water recovery pipe 17 are provided. Since the valve 16 is kept on and opened, the condensed water in the condensate recovery tank 23 is filled to the condensate collection tank 2 through the condensate recovery pipe 17.
한편, 보일러(1)의 계속되는 가동으로 보일러내의 관수가 설정량보다 작아짐이 감지되면 펌프(13)가 가동하여 응축수 모음탱크(2) 내의 응축수를 보일러(1)의 내부로 급수하게 되는데, 이 경우에는 전술한 바와는 반대로 응축수 회수관(17)상에 설치된 제3밸브(16)는 오프되어 폐쇄된 상태를 유지하고 응축수 공급관(11) 및 급수관(15)상에 설치된 제1, 2밸브(12)(14)가 온되어 개방된 상태를 유지하게 되므로 펌프(13)의 구동에 따라 응축수 모음탱크(2) 내에 있던 응축수가 응축수 공급관(11) 및 급수관(15)을 거쳐 보일러(1)의 내부로 급수된다.On the other hand, when it is detected that the water in the boiler is smaller than the set amount due to the continuous operation of the boiler 1, the pump 13 is operated to supply the condensed water in the condensate collection tank 2 to the inside of the boiler 1, in this case In contrast to the above, the third valve 16 installed on the condensate return pipe 17 is turned off to maintain the closed state, and the first and second valves 12 provided on the condensate supply pipe 11 and the water supply pipe 15 are provided. (14) is turned on to maintain the open state, so that the condensed water in the condensate collection tank (2) through the condensate supply pipe 11 and the water supply pipe (15) in accordance with the operation of the pump 13 inside the boiler (1) Watered by
상기한 바와 같이 구동하면서 응축수를 지속적으로 공급하는 과정에서 응축수 모음탱크(2) 내의 압력이 보일러(1)의 압력보다 높아질 경우에는 스팀관(18)과 균압관(20)사이에 체크밸브(19)가 설치되어 있어 응축수 모음탱크(2) 내의 압력이 보일러(1) 내의 압력과 균압을 유지하게 되므로 보일러를 정상적으로 가동시킬 수 있게 되는 것이다.When the pressure in the condensate collection tank 2 becomes higher than the pressure of the boiler 1 in the process of continuously supplying the condensate while driving as described above, the check valve 19 between the steam pipe 18 and the pressure equalizing pipe 20. ) Is installed so that the pressure in the condensate collection tank (2) maintains the pressure and the equal pressure in the boiler (1) so that the boiler can be operated normally.
이상에서 설명한 바와 같이 본 고안은 응축수 공급관과 응축수 회수관, 그리고 급수관상에 설치된 각 밸브의 개폐시기를 제어하여 응축수의 순환경로를 절환하므로서 펌프의 구동으로 회수된 응축수를 응축수 모음탱크측으로 회수하거나, 보일러측으로 급수할 수 있게 되므로 고가의 콤프레셔를 설치할 필요가 없게 되고, 이에 따라 보일러의 설치에 따른 설비비를 절감할 수 있게 됨은 물론 유지 관리비를 절감할 수 있게 되는 효과를 얻게 된다.As described above, the present invention controls the opening / closing time of each valve installed on the condensate supply pipe, the condensate recovery pipe, and the water supply pipe, thereby switching the condensate circulation path to recover the condensate collected by the driving of the pump to the condensate collection tank side, Since the water can be supplied to the boiler side, it is not necessary to install an expensive compressor, thereby reducing the equipment cost according to the installation of the boiler as well as the maintenance cost.
