본 발명은 흡수식 사이클의 흡수기에 관한 것으로, 특히 흡수액과 냉매 증기의 직접 접촉을 이용하여 냉매증기의 흡수량을 증가시키어 시스템의 효율을 향상하도록 한 흡수식사이클의 직접접촉흡수기에 관한 것이다.The present invention relates to an absorber of an absorption cycle, and more particularly, to a direct contact absorber of an absorption cycle to improve the efficiency of the system by increasing the absorption amount of the refrigerant vapor by using the direct contact of the absorption liquid and the refrigerant vapor.
종래의 암모니아 흡수식 사이클은, 발생기(재생기), 응축기, 증발기, 흡수기에 의해 구성되고, 재생기은 열원으로부터 열을 받아 고농도의 작동용액(암모니아 수용액, 이하 강용액)으로부터 냉매인 암모니아를 증발시켜 암모니아 냉매 증기를 얻음과 동시에 일부 암모니아증발에 의해 생긴 저농도의 암모니아 수용액(이하 약용액이라 함)을 만들어 준다. 응축기는 재생기로부터 보내져온 냉매 증기를 응축하여 액냉매로 만들어 주는데 이때 냉매 증기로부터 열량을 빼앗아 응축시키기위해 냉각수를 사용한다.The conventional ammonia absorption cycle consists of a generator (regenerator), a condenser, an evaporator, and an absorber. The regenerator receives heat from a heat source and evaporates ammonia, which is a refrigerant, from a high concentration of the working solution (ammonia aqueous solution, hereinafter, a strong solution) to vaporize the ammonia refrigerant. At the same time, a low concentration of ammonia solution (hereinafter referred to as medicinal solution) produced by some ammonia evaporation is produced. The condenser condenses the refrigerant vapor sent from the regenerator into liquid refrigerant, which uses cooling water to take heat from the refrigerant vapor and condense it.
그리고, 증발기는 응축기로부터 보내져 온 액냉매를 다시 증발시켜 주어 냉매 증기로 만들어 주는데 이때 액냉매를 증발시켜 주는데 필요한 열량은 온도가 상승 되어 들어온 냉수로부터 공급하여 준다.Then, the evaporator evaporates the liquid refrigerant sent from the condenser to make the refrigerant vapor. At this time, the amount of heat required to evaporate the liquid refrigerant is supplied from the cold water which has been heated up.
흡수기는 증발기 로부터 보내져 온 냉매 증기를 재생기로부터 보내져 온 약용액이 흡수하도록 하여 원래의 재생기의 초기 농도의 강용액을 만들어 주는 역활을 하는데 이때 흡수를 촉진 하기 위해 열량을 제거 하여 주어야 하고, 이 열량 제거를 위해 냉각수를 이용한다.The absorber serves to absorb the refrigerant vapor sent from the evaporator and absorb the medicinal solution sent from the regenerator to make a strong solution of the initial concentration of the original regenerator. At this time, the calorie must be removed to promote absorption. Use coolant for
이러한 종래의 흡수식사이클의 흡수기는 제1도에 도시된 바와 같이, 열교환기인 실외기(or 방열장치)를 거치는 작동점 4의 저온의 열교환유체(냉각수)가 재생기로부터 보내져 온 작동점 1의 약용액과 열교환하여 증발기로부터 보내져 온 작동점 3의 증기를 흡수하는데 발생하는 흡수열을 흡수기 외부로 방출하는 구조로 되어 있으며 열교환기 내부는 동시에 저온유체와 저농도액, 증기의 접촉을 가능케 하는 구조로 구성되어있다.As shown in FIG. 1, the absorber of the conventional absorption cycle includes the chemical solution of the operating point 1 from which the low-temperature heat exchange fluid (cooling water) of the operating point 4, which passes through the outdoor unit (or heat sink) that is a heat exchanger, is sent from the regenerator. It has a structure that releases the heat of absorption generated from absorbing steam at operating point 3 sent from the evaporator to the outside of the absorber, and the inside of the heat exchanger is configured to allow the contact of low temperature fluid, low concentration liquid and steam at the same time. .
이러한 종래의 흡수식사이클에서는 일단 흡수기를 벗어난 용액과 증기의 접촉면적이 매우 제한적이며 운전 조건에 따라 과냉되는 용액의 여분의 흡수능력 또는 증기의 저온을 이용하는 흡수능력을 이용하지 않는 문제점이 있었다.In such a conventional absorption cycle, there is a problem that the contact area of the solution and the vapor out of the absorber is very limited and does not use the extra absorption capacity of the supercooled solution or the absorption capacity using the low temperature of the steam depending on the operating conditions.
본 발명은, 이러한 종래 기술의 문제점을 해결 하기 위한 것으로, 흡수기를 나온 고농도액의 흡수 능력을 재활용하여 냉매 증기 흡수량의 극대화를 통해 용액 흡수 능력의 낭비를 막아 전체 시스템의 효율을 증가 시킬수 있는 흡수식사이클의 직접접촉흡수기의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art, an absorption cycle that can increase the efficiency of the overall system by preventing the waste of the solution absorption capacity by maximizing the amount of refrigerant vapor absorption by recycling the absorption capacity of the high concentration liquid from the absorber To provide a direct contact absorber.

And a refrigerant inlet pipe (55) and an outlet pipe (57) connected to the suction side (31) and the discharge side (33) of the solution pump (30) for circulating a high concentration liquid. have.
한편, 상기 폐쇄공간(51)내에는 패킹재(59)가 설치되어 용액의 분배 및 냉매증기와의 접촉면적 및 시간을 최적화하고 있다.Meanwhile, a packing material 59 is installed in the closed space 51 to optimize the distribution of the solution and the contact area and time with the refrigerant vapor.
한편, 분배기(40)는 용액펌프(30)에서 고압으로 토출된 강용액을 상기 직접접촉흡수기와 발생 열교환기(미도시)측으로 적절한 유량비로 분배하여 공급한다.Meanwhile, the distributor 40 distributes the steel solution discharged at high pressure from the solution pump 30 to the direct contact absorber and the generated heat exchanger (not shown) at an appropriate flow rate.
이러한 본 발명의 흡수식사이클의 작용을 설명한다.The operation of the absorption cycle of the present invention will be described.
먼저, 저온의 열 교환기(10)을 거치며 냉매 증기를 흡수한 강용액(작동점 1) 은 고압의 증기 발생용 열 교환기(미도시) 로 이송 되기 위해 용액 펌프(30)의 흡입측(31) 에 보내진다.First, the strong solution (operating point 1) absorbing the refrigerant vapor through the low temperature heat exchanger 10 is transferred to the suction side 31 of the solution pump 30 to be transferred to a high pressure steam generating heat exchanger (not shown). Is sent to.
상기 흡입측의 강용액은 용액펌프(30)에 의해 고압으로 토출 되며 분배기(40)에 의해 적절한 유량비로 나누어져 직접접촉 흡수기(50)와 상기 증기발생용 열 교환기 측으로 각각 공급된다.The suction solution on the suction side is discharged at high pressure by the solution pump 30 and divided by an appropriate flow rate ratio by the distributor 40 and supplied to the direct contact absorber 50 and the steam generator heat exchanger, respectively.

The remaining refrigerant vapor is supplied to the absorber 10 through the refrigerant vapor outlet pipe 53.
이상, 설명한 바와 같이, 본 발명에 따르면, 흡수기를 나온 강용액의 나머지의 흡수능력을 이용하여 증발기로부터의 냉매증기를 흡수시키어 냉매 증기 흡수량의 극대화를 통해 용액 흡수능력의 낭비를 막아 전체 시스템의 효율을 증가시킬 수 있다.As described above, according to the present invention, by absorbing the refrigerant vapor from the evaporator by using the absorption capacity of the rest of the strong solution exiting the absorber to maximize the amount of refrigerant vapor absorption to prevent the waste of the solution absorption capacity of the overall system efficiency Can be increased.
