It relates to a structure piping thawing system using hot water capable of quickly and efficiently thawing frozen pipe parts by controlling the system with
단독주택이나 연립주택 또는 아파트와 같은 공동주택의 수도배관이나 보일러 온수 배관 등의 경우, 보온이 철저히 되지 않은 경우 동절기 추위에 의해 배관이 얼게 되는 현상이 자주 발생하게 된다. 이 같은 현상은 주택에 한정되는 것은 아니며, 여러 건축물 등에서도 동절기 한파 등에 의해 흔히 발생될 수 있는 현상이다. In the case of water pipes or boiler hot water pipes of apartment houses such as detached houses, row houses, or apartments, if the insulation is not thoroughly maintained, the pipes are often frozen due to the cold in winter. This phenomenon is not limited to houses, and is a phenomenon that can often occur in various buildings due to cold waves in the winter.
이와 같이 배관이 동결되어 얼게 되면, 배관을 통해 공급되는 수도 등의 공급이 차단되게 되어, 일상생활에 막대한 차질이 발생하게 되고, 이를 해빙하는 데에는 많은 노력과 비용이 발생하게 된다. 기존의 동결된 배관의 해빙을 위해 적용되고 있는 기술들을 보면, 기본적으로 배관 외부를 가열하는 방식과 배관 내부에 조치를 취하는 방식으로 구분해볼 수 있는데, 배관 외부를 가열하는 등 배관 외부에서 조치를 취하는 방식의 경우 특히, 매립된 배관에 대해서는 조치가 상당히 제약되는 근본적 문제를 안고 있다. 이에 비해 상대적으로 배관 내부에 조치를 취하는 방식의 경우, 매립된 배관에 대한 조치로 바람직한데, 기존의 배관 내부에 조치를 취하는 방식 중 대표적인 것이 바로, 스팀이나 열선을 이용하여 배관 내부에 고온의 스팀이나 또는 열선을 주입하여 동결된 배관 내부를 녹이는 방식이 있다. 그러나, 이와 같은 기존 방식의 경우, 배관의 길이가 길수록 또는 배관이 여러 번 꺽여 있는 경우 등에 있어서는 그 효율이 급격히 저하되는 단점을 안고 있고, 전문가의 숙력된 노하우가 동반되지 않고는 해빙 효율이 많이 저하되게 된다. In this way, when the pipe freezes and freezes, the supply of water or the like supplied through the pipe is blocked, resulting in a huge disruption to daily life, and a lot of effort and cost to thaw it. Looking at the technologies applied for thawing existing frozen pipes, they can be basically divided into a method of heating the outside of the pipe and a method of taking measures inside the pipe. In the case of the method, it has a fundamental problem that measures are significantly limited, especially for buried pipes. On the other hand, in the case of the method of taking measures on the inside of the pipe, it is preferable to take action on the buried pipe. Among the methods of taking action on the inside of the existing pipe, the representative method is high-temperature steam inside the pipe using steam or a hot wire. There is a method of melting the inside of a frozen pipe by injecting a hot wire or a hot wire. However, in the case of such an existing method, the efficiency is rapidly reduced as the length of the pipe is long or when the pipe is bent several times, and the thawing efficiency is greatly reduced without the skilled know-how of experts. It becomes.

상기 (선행특허 문헌)에 개시되어 있는 스팀 해빙장치의 경우, 스팀 분사를 통해 배관을 해빙하는 과정에서 나오는 용융수를 별도의 라인을 통해 배출시키면서 해빙이 효율성을 높이고자 하는 것이나, 이 역시 앞서 언급한 배관의 길이가 길수록 또는 배관의 꺽임이 많을수록 그 효율이 급격히 저하되는 문제는 동일하게 안고 있다. In the case of the steam thawing device disclosed in the above (prior patent document), the melting water from the process of thawing the pipe through steam injection is discharged through a separate line to increase the efficiency of thawing, but this is also mentioned above. The longer the length of a pipe or the more bends in the pipe, the more rapidly the efficiency decreases.
따라서, 기존의 배관 해빙기술과 달리, 매립된 배관의 길이나 동결된 부위의 길이 내지 배관의 꺽임의 정도에 불문하고, 신속하고 효율적으로 동결된 배관을 해빙할 수 있고, 특히 정밀한 제어기능을 통해, 비숙련공에 의해서도 효율적으로 해빙과정이 이루어질 수 있는 해빙시스템에 대한 니즈는 증대되고 있다. Therefore, unlike the existing pipe thawing technology, it is possible to thaw the frozen pipe quickly and efficiently, regardless of the length of the buried pipe, the length of the frozen part, or the degree of bending of the pipe. However, the need for a thawing system that can efficiently perform the thawing process even by unskilled workers is increasing.

An object of the present invention is to use hot water to quickly and efficiently thaw frozen pipe parts even when buried pipes are bent in various ways, as well as to reuse melted water immediately according to the temperature of the melted water.

상기 회수/리턴제어모듈(810)은 상기 온도센서(60)에 의해 측정된 용융수의 온도를 기반으로 용융수의 회수관로(40)를 통한 회수 내지 재가열관로(50)를 통한 리턴 여부를 제어하는 구성으로, 앞서 살펴본 바와 같이 동결된 배관부위에 대한 해빙작업 과정에서 회수되는 용융수를 일괄적으로 재가열하는 것이 아니라, 용융수의 온도가 해빙작업에 활용될 정도로 충분히 일정 온도 이상(일 예로, 50~60도 내외의 온도)을 유지하고 있는 경우에는 즉시 재사용하는 것이 전체적인 시스템의 효율을 높일 수 있기 때문에, 상기 회수/리턴제어모듈(810)에서는 상기 온도센서(60)에 의해 측정된 용융수의 온도를 기반으로 용융수의 회수관로(40)를 통한 회수 내지 재가열관로(50)를 통한 리턴 여부를 제어하게 된다. The recovery/return control module 810 controls whether the melt water is recovered through the recovery pipe line 40 or returned through the reheating pipe line 50 based on the temperature of the melt water measured by the temperature sensor 60. In the configuration, as described above, rather than reheating the melted water recovered in the process of thawing the frozen piping part in batches, the temperature of the melted water is sufficiently high enough to be used for the thawing work (for example, Since the efficiency of the overall system can be increased by immediately reusing it when the temperature is maintained at around 50 to 60 degrees), the melt water measured by the temperature sensor 60 in the recovery/return control module 810 Based on the temperature of the molten water, whether to return through the recovery pipe 40 or return through the reheating pipe 50 is controlled.
상기 제1제어모듈(820)은 해빙 대상이 되는 구조물 배관의 전체 길이 및 전체 배관에서 해빙 대상이 되는 동결된 배관부위의 길이를 기반으로 온수의 주입 및 용융수의 회수 시간 및 간격을 설정하여 제어하는 구성으로, 즉, 본 발명의 해빙시스템에서는 해빙을 위해 활용되는 온수의 주입 및 해빙 과정에서 산출되는 용융수의 회수의 과정을 현장 상황에 맞게 맞춤형으로 주입과 회수 간격 등을 제어하는 것이 전체적인 해빙작업의 효율을 높이고 신속히 작업을 완료하는데 결정적인 역할을 하는 것이기 때문에, 상기 제어부(80)에 의한 제어과정이 중요하다. 이러한 제어과정 중 상기 제1제어모듈(820)에서는, 기본적으로 구조물 배관의 전체 길이와 함께 전체 배관 중 해빙 대상이 되는 동결된 배관부위의 길이 등을 변수로 하여 온수의 주입 및 용융수의 회수 시간 및 간격을 설정/제어하게 된다. 일 예로, 전체적인 배관 길이도 길고 동결된 배관부위의 길이도 긴 현장에서는 기본적으로 주입되는 온수의 주입시간을 길게 하고 또한 온수의 주입과 용융수의 회수 간격도 길게 제어하고, 반대로 전체적인 배관 길이도 상대적으로 짧고 동결되 배관부위 길이도 짧은 현장에서는 기본적으로 주입되는 온수의 주입시간 및 온수의 주입과 용융수의 회수 간격도 짧게 제어할 수 있다. The first control module 820 controls by setting the time and interval for the injection of hot water and the recovery of melted water based on the total length of the pipe of the structure to be thawed and the length of the frozen pipe part to be thawed in the entire pipe. That is, in the thawing system of the present invention, the process of injecting hot water used for thawing and recovering melted water calculated in the thawing process is tailored to the site situation and controlling the injection and recovery intervals as a whole. Since it plays a decisive role in increasing work efficiency and completing work quickly, the control process by the control unit 80 is important. During this control process, in the first control module 820, basically, the length of the frozen pipe part to be thawed among the entire pipe along with the entire length of the structure pipe is used as a variable, and the injection of hot water and the recovery time of melt water and set/control the interval. For example, in a field where the length of the entire pipe is long and the length of the frozen pipe part is long, the injection time of the hot water injected is basically long, and the interval between the injection of the hot water and the recovery of the melted water is controlled to be long, and conversely, the overall pipe length is relatively long. In a field where the length of the pipe part is short and frozen, the injection time of the basically injected hot water and the injection interval of the hot water and the recovery of the melted water can be shortened.
상기 제2제어모듈(830)은 상기 온도센서(60)에 의해 측정된 용융수의 온도를 기반으로 온수의 주입 및 용융수의 회수 시간 및 간격을 설정하여 제어하는 구성으로, 앞서 살펴본 상기 제1제어모듈(820)에 의한 해빙 대상이 되는 구조물 배관의 전체 길이 및 전체 배관에서 해빙 대상이 되는 동결된 배관부위의 길이라는 변수 외에도, 각 현장의 상황에 따라 상대적으로 주입된 온수의 온도가 급격히 낮아지는 현장이 있고, 상대적으로 온수의 온도 내지 용융수의 온도가 일정 수준을 유지하는 현장이 있는 등 현장 상황이 다르게 나타나기 때문에, 이러한 각각의 현장에서의 실제 주입되는 온수 내지 회수되는 용융수의 온도를 기반으로 온수의 주입 및 용융수의 회수 시간 및 간격을 설정하여 제어하는 것이 각 현장별 해빙작업의 효율을 높이고 신속히 작업을 완료하는데 중요하게 작용하게 된다. 따라서, 일 예로, 상기 제2제어모듈(830)에서는 상기 온도센서(60)에 의해 측정된 용융수의 온도가 높게 유지되는 경우에는, 주입되는 온수의 주입시간 및 온수의 주입과 용융수의 회수 간격을 상대적으로 길게 제어하고, 반대로 상기 온도센서(60)에 의해 측정된 용융수의 온도가 급격히 낮아지는 경우에는, 주입되는 온수의 주입시간 및 온수의 주입과 용융수의 회수 간격을 상대적으로 짧게 제어할 수 있다. The second control module 830 is configured to set and control hot water injection and melt water recovery times and intervals based on the temperature of the melt water measured by the temperature sensor 60. In addition to the variables of the total length of the structure pipe to be thawed by the control module 820 and the length of the frozen pipe part to be thawed in the entire pipe, the temperature of the relatively injected hot water is rapidly lowered according to the situation at each site. Since there are sites where the temperature of hot water or melt water is relatively maintained at a certain level, the site situation appears different, so the temperature of the actually injected hot water or the melt water recovered at each site Based on this, setting and controlling the time and interval of hot water injection and melting water recovery is important to increase the efficiency of thawing work at each site and complete the work quickly. Therefore, for example, in the second control module 830, when the temperature of the melted water measured by the temperature sensor 60 is maintained high, the injection time of the injected hot water and the injection of the hot water and the recovery of the melted water When the interval is controlled to be relatively long and, conversely, when the temperature of the melt water measured by the temperature sensor 60 rapidly decreases, the injection time of the injected hot water and the interval between the injection of the hot water and the recovery of the melt water are relatively short. You can control it.
상기 제3제어모듈(840)은 해빙 대상이 되는 구조물 배관 시점으로부터 동결된 배관부위까지의 거리를 기반으로 온수의 주입 및 용융수의 회수 시간 및 간격을 설정하여 제어하는 구성으로, 실제 배관에서 해빙작업의 대상이 되는 동결된 배관부위가 배관 시점 즉, 입구로부터 가까이 있는 경우와 입구로부터 굉장히 깁숙히(길게)들어가야 있는 경우 등이 현장에 따라 다르게 나타나는데, 이러한 각각의 현장에서의 실제 배관 시점으로부터 동결된 배관부위까지의 거리 차이에 따라 온수의 주입 및 용융수의 회수 시간 및 간격을 설정하여 제어하는 것이 각 현장별 해빙작업의 효율을 높이고 신속히 작업을 완료하는데 역시 중요하게 작용하게 된다. 따라서, 일 예로, 상기 제3제어모듈(840)에서는 실제 배관 시점으로부터 동결된 배관부위까지의 거리가 긴 경우에는 주입되는 온수의 주입시간 및 온수의 주입과 용융수의 회수 간격을 상대적으로 길게 제어하고, 반대로 실제 배관 시점으로부터 얼마 되지 않은 짧은 거리에 동결된 배관부위가 있는 경우에는 주입되는 온수의 주입시간 및 온수의 주입과 용융수의 회수 간격을 상대적으로 짧게 제어할 수 있다. The third control module 840 sets and controls the time and interval for the injection of hot water and the recovery of melted water based on the distance from the point of view of the piping of the structure to be thawed to the frozen piping portion, and controls the thawing in the actual piping. The frozen piping part, which is the target of work, appears differently depending on the site, such as the case where the piping point is close to the inlet and the case where it is very long (long) from the inlet. Setting and controlling the time and interval for the injection of hot water and the recovery of melted water according to the difference in the distance to the piped part is also important for increasing the efficiency of the thawing work at each site and completing the work quickly. Therefore, for example, in the third control module 840, when the distance from the actual piping point to the frozen piping part is long, the injection time of the injected hot water and the interval between the injection of the hot water and the recovery of the melted water are relatively long. Conversely, if there is a frozen pipe part at a short distance from the actual piping point, the injection time of the injected hot water and the injection interval of the hot water and the recovery of the melted water can be controlled relatively short.
상기 제4제어모듈(850)은 동결된 배관부위에 대한 해빙과정에서 상기 주입구(310) 내지 주입관로(30)를 통해 주입되는 온수 또는 회수되는 용융수의 유량 내지 속도 변화를 기반으로 한 해빙의 진행 정도에 따라 온수의 주입 및 용융수의 회수 시간 및 간격을 설정하여 제어하는 구성이다. 현장 상황에 따라 동결된 배관부위에 대한 해빙의 진행 정도는 차이가 발생하게 되는데, 일 예로 상대적으로 해빙 작업의 진행정도가 빠르게 진행되는 경우에는 동일한 시간 간격 내에서도 주입되는 온수 내지 회수되는 용융수의 유량(속도)의 변화가 크게 증가하게 되고, 상대적으로 해빙 작업의 진행 정도가 느리게 진행되는 경우에는 동일한 시간 간격 내에서도 주입되는 온수 내지 회수되는 용융수의 유량(속도)의 변화가 느리게 나타나게 된다. 이와 같이 해빙 작업의 진행 정도가 상대적으로 느린 현장에서는 더 단단하게 동결되어 있는 부위로 볼 수 있기 때문에, 상기 제4제어모듈(850)에서는 이러한 경우 좀 더 자주 더 뜨거운 온수에 의한 가압과 접촉이 이루어질 수 있도록 상대적으로 온수의 주입 및 용융수의 회수 시간 및 간격을 짧게 제어할 수 있다. The fourth control module 850 determines the level of thawing based on the flow rate or speed change of the hot water injected through the inlet 310 to the injection pipe 30 or the melted water recovered during the process of thawing the frozen pipe portion. It is a configuration that controls by setting the time and interval for the injection of hot water and the recovery of melted water according to the degree of progress. Depending on the site situation, the progress of thawing on the frozen pipe part is different. For example, when the progress of the thawing operation is relatively fast, the flow rate of injected hot water or recovered melt water even within the same time interval. The change in (speed) greatly increases, and when the progress of the thawing operation is relatively slow, the change in the flow rate (speed) of the injected hot water or the recovered meltwater appears slowly even within the same time interval. In this way, since it can be seen as a more solidly frozen part in a site where the progress of the thawing operation is relatively slow, the fourth control module 850 will pressurize and contact with hot water more often in this case. It is possible to control the injection of hot water and the recovery time and interval of melt water relatively short so that
이와 같이, 본 발명의 해빙시스템에서 상기 제어부(80)는, 용융수의 온도에 따라 즉시 재사용과 가열 후 재사용을 구분하여 제어 가능하고 또한, 전체 배관의 길이 및 배관 중 동결된 배관부위의 길이를 기반으로, 또는 주입관로(30) 또는 회수관로(40)를 통해 회수되는 온수 또는 용융수의 온도나, 배관 입구에서 동결된 배관부위까지의 거리 또는 해빙 과정에서의 해빙의 진행 정도 등에 따라 해빙을 위해 제어되는 온수 등의 주입/회수 간격을 조절/제어하여, 현장 상황 및 진행 상황에 맞춰 능동적으로 시스템을 제어하여 신속하고 효율적으로 동결된 배관부위에 대한 해빙이 가능케 된다. As described above, in the thawing system of the present invention, the control unit 80 can distinguish and control immediate reuse and reuse after heating according to the temperature of the melted water, and also determines the length of the entire pipe and the length of the frozen portion of the pipe. Based on this, the temperature of the hot water or melted water recovered through the injection pipe 30 or the return pipe 40, the distance from the pipe inlet to the frozen pipe part, or the degree of thawing in the thawing process, etc. By adjusting/controlling the injection/return interval of hot water, etc., which is controlled for safety, it is possible to thaw frozen pipe parts quickly and efficiently by actively controlling the system according to the on-site situation and progress.
한편, 도 3을 참조하면, 본 발명의 다른 실시예에 따른 온수를 활용한 구조물 배관 해빙시스템은, 상기 주입구(310) 상에 온수를 주입하는 주입관로(30)와 용융수를 회수하는 회수관로(40)가 병렬적으로 형성되는 구조를 적용할 수 있다. On the other hand, referring to FIG. 3, in the structure pipe thawing system using hot water according to another embodiment of the present invention, the injection pipe 30 for injecting hot water on the inlet 310 and the recovery pipe for recovering melted water (40) can be applied to the structure formed in parallel.
이와 같이 주입구(310)에 주입관로(30)와 회수관로(40)가 병렬적으로 적용되는 경우에는, 배관 내에서 주입된 온수가 일정 압력으로 지속적으로 결빙된 배관부위를 가압/접촉하게 되는 앞선 실시예와 달리, 배관 내에서 주입된 온수와 회수되는 용융수가 순환 즉, 서큘레이션(circulation)함으로써 순환되는 온수와 용융수가 반복적으로 결빙된 배관부위에 일종의 충격을 가하는 작용까지 기대될 수 있기 때문에 그로 인한 효과도 기대될 수 있고 또한, 온수의 주입과 용융수의 회수 과정에서의 시간적 간격도 줄일 수 있는 효과도 기대될 수 있다. In this way, when the injection pipe 30 and the return pipe 40 are applied in parallel to the inlet 310, the hot water injected in the pipe pressurizes/contacts the frozen pipe portion continuously at a certain pressure. Unlike the embodiment, since the hot water injected and the melted water recovered in the pipe are circulated, that is, by circulating, even the action of applying a kind of impact to the piping portion where the circulated hot water and the melted water are repeatedly frozen can be expected. In addition, the effect of reducing the time interval in the process of injecting hot water and recovering melted water can also be expected.
