Description

밀폐구역내의 복합가스 멀티 측정시스템{Composition Gas multi measurement system of sealing zone}Composition Gas multi measurement system of sealing zone

본 발명은 밀폐구역내의 복합가스 멀티 측정시스템에 관한 것으로서, 특히 사람이 지하탱크와 같은 밀폐구역에 진입하기 전에 미리 밀폐구역내의 가스를 측정함으로써 안전을 보장할 수 있도록 된 밀폐구역내의 복합가스 멀티 측정시스템에 관한 것이다. The present invention relates to a multi-gas multi-measurement system in an enclosed area, and in particular, multi-gas multi-measurement in an enclosed area to ensure safety by measuring gas in the enclosed area before a person enters an enclosed area such as an underground tank. It's about the system.

일반적으로, 작업자가 산소결핍이나 유해 위험성 가스로 인한 중독, 화재폭 발 등의 위험이 있는 밀폐구역 진입 시, 먼저 가스측정기를 활용하여 내부의 유해가스 농도를 측정하여 안전한지를 확인한 후에 진입하고 있다. In general, when a worker enters a confined area where there is a risk of poisoning due to oxygen deficiency or harmful gas, fire explosion, etc., first enters after measuring the concentration of harmful gas inside by using a gas meter to check whether it is safe.

특히, 선박 또는 해양공사에서는 밀폐구역에 대한 복합가스(산소 및 가연성 가스 등) 측정을 통한 작업 구역 출입을 명문화하고 있다. 그런데, 밀폐구역마다 복합가스 측정기를 개별적으로 설치하기에는 구입 비용과 안전 감시자 증가 요인이 되고 있다.In particular, ships or offshore constructions stipulate access to working areas by measuring complex gases (such as oxygen and flammable gases) in enclosed areas. However, it is becoming a factor to increase the cost of purchase and safety monitors to install the multi-gas meter separately in each closed area.

종래 밀폐구역내 가스 농도를 측정하는 방법을 살펴보면, 밀폐구역 바닥에 산소 측정기를 고정 설치하고 출입구에서 산소 농도를 확인한다. 즉, 밀폐구역 하부에 산소 측정기를 설치한 후 케이블을 연결하여 밀폐구역 진입 시, 상부에서 산소 농도를 미리 확인한 후 하부로 내려가 작업한다. In the conventional method of measuring the gas concentration in the closed area, the oxygen meter is fixedly installed on the bottom of the closed area and the oxygen concentration is checked at the entrance. In other words, when the oxygen meter is installed at the bottom of the closed area and the cable is connected to the closed area, it is necessary to check the oxygen concentration in the upper part before going down.

그런데, 이러한 종래 방법의 경우, 밀폐구역의 특정 위치에 한정하여 단일의 산소 가스농도만 측정함으로써 필요에 따라서는 가스 측정기를 추가로 설치해야 하기 때문에 추가적인 비용이 발생되며, 또한 이들을 별도로 관리해야 하는 문제점이 있다. However, in the case of this conventional method, since only a single oxygen gas concentration is limited only to a specific position of the closed zone, additional gas meters are required to be installed according to need, so that additional costs are incurred, .

이와 더불어, 가스 측정기의 설치 및 해체 시 무거워서 작업자가 회피하는 경향이 있다. 즉, 가스 측정기 설치 시 밀폐구역 하부로 가스 측정기와 케이블을 들고 내려가서 설치해야 하기 때문에 작업자의 가스 측정기 설치 기피 현상이 발생될 뿐만 아니라 작업 효율 저하를 초래한다. In addition, there is a tendency that the worker is avoided because of the heavy installation and disassembly of the gas measuring instrument. In other words, when installing the gas meter, the gas meter and the cable should be lowered and installed under the sealed area, thereby preventing the operator from installing the gas meter and causing a decrease in working efficiency.

이에 본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 밀폐구역내의 복합가스를 동시에 측정하고 복수개소의 복합가스 농도를 통합하여 관리할 수 있으며 간편하게 설치할 수 있도록 된 밀폐구역내의 복합가스 멀티 측정시스템을 제공하는데 그 목적이 있다. Accordingly, the present invention is to solve the above problems, the multi-gas measurement system in a closed zone that can simultaneously measure the complex gas in the closed zone and integrate and manage the concentration of a plurality of complex gas and can be easily installed The purpose is to provide.

상기와 같은 목적을 달성하기 위하여 본 발명에 따른 밀폐구역내의 복합가스 멀티 측정시스템은, 복수의 밀폐구역내에 각각 설치되어 밀폐구역내의 복합가스를 흡입하기 위한 복수개의 흡입호스와; 상기 복수개의 흡입호스가 연결되는 멀티 매니폴드와; 상기 복수개의 흡입호스에서 멀티 매니폴드로 유입되는 복합가스를 펌핑하는 펌프와; 상기 펌프의 작용으로 유입되는 복합가스의 농도를 측정하는 복합가스 측정기를 포함하여 이루어진 것을 특징으로 한다. In order to achieve the above object, the multi-gas multi-measuring system in the closed zone according to the present invention includes a plurality of suction hoses respectively installed in the plurality of closed zones to suck the composite gas in the closed zone; A multi-manifold to which the plurality of suction hoses are connected; A pump for pumping the mixed gas flowing into the multi-manifold from the plurality of suction hoses; It characterized in that it comprises a multi-gas measuring device for measuring the concentration of the multi-gas introduced by the action of the pump.

여기에서, 상기 멀티 매니폴드에는 상기 복수개의 흡입호스로부터 유입되는 복합가스 유입을 조절하기 위한 유입조절밸브가 부착될 수 있다. Here, the multi manifold may be attached to the inlet control valve for controlling the inlet of the composite gas flowing from the plurality of suction hoses.

또한, 상기 복수개의 흡입호스의 끝단부 및 상기 멀티 매니폴드와 펌프의 사이에는 먼지를 필터링하기 위한 에어필터가 설치될 수 있다. In addition, an air filter for filtering dust may be installed between the end portions of the plurality of suction hoses and the multi manifold and the pump.

또한, 상기 펌프(130)와 복합가스 측정기의 사이에는 복합가스 유량을 조절하기 위한 유량조절밸브가 설치될 수 있다. In addition, a flow regulating valve may be installed between the pump 130 and the combined gas measuring device to adjust the combined gas flow rate.

또한, 상기 복합가스 측정기에서 측정된 복합가스 농도를 디스플레이하기 위한 모니터가 더 구비될 수 있다. In addition, a monitor for displaying the composite gas concentration measured in the composite gas meter may be further provided.

또한, 상기 복합가스 측정기는 산소 및 가연성 가스 농도를 동시에 측정할 수 있다. In addition, the composite gas meter can measure the oxygen and flammable gas concentration at the same time.

또한, 상기 흡입호스에는 밀폐구역에 탈부착시키기 위한 탈부착 장치가 설치될 수 있다. In addition, the suction hose may be a detachable device for attaching and detaching in the closed area.

본 발명에 따르면, 복합 가스측정기를 이용함으로써 밀폐구역내의 산소/가연성 가스 등의 복합가스를 동시에 측정할 수 있을 뿐만 아니라 멀티 매니폴드를 적용함으로써 복수개소의 복합가스 농도를 측정하여 통합 관리할 수 있다. 이에 따라, 작업자가 작업을 위해 특정한 밀폐구역에 출입하는 경우 멀티 매니폴드에 부착된 유입조절밸브를 조작하여 해당되는 밀폐구역 내부의 가스농도를 미리 측정하고 진입함으로써 작업자의 안전을 보장할 수 있다. 또한, 흡입호스만 밀폐구역 내부에 설치하고, 그 이외의 복합가스 측정기 등은 밀폐구역 외부에 설치함으로써, 작업자의 작업 능률 향상을 도모할 수 있다. According to the present invention, it is possible to simultaneously measure a complex gas such as oxygen / flammable gas in an enclosed area by using the complex gas meter, and to measure and manage the complex gas concentration in a plurality of places by applying a multi-manifold. . Accordingly, when the worker enters and exits a specific closed area for work, the safety of the worker may be guaranteed by measuring and entering the gas concentration in the corresponding closed area in advance by manipulating the inlet control valve attached to the multi-manifold. In addition, by installing only the suction hose inside the sealed space, and installing the other complex gas measuring instruments outside the sealed zone, it is possible to improve the work efficiency of the operator.

In addition, the suction hose 110 may be provided with a detachable device (not shown) such as a magnet for detachably attaching to the hermetic zone.

상기 멀티 매니폴드(120)는 하나의 본줄기 관으로부터 여러 개의 지관이 갈라져 있는 관으로서, 상기 복수개의 흡입호스(110)가 멀티 매니폴드(120)에 연결된다. 이때, 상기 멀티 매니폴드(120)에는 상기 복수개의 흡입호스(110)로부터 유입되는 복합가스 유입을 적절히 조절하기 위해 유입조절밸브(121)가 부착될 수 있다. The multi-manifold 120 is a tube in which a plurality of branch tubes are separated from one main stem pipe, and the plurality of suction hoses 110 are connected to the multi-manifold 120. The inflow control valve 121 may be attached to the multi-manifold 120 to appropriately control inflow of the complex gas introduced from the plurality of suction hoses 110.

상기 펌프(130)는 상기 복수개의 흡입호스(110)에서 멀티 매니폴드(120)로 유입되는 복합가스를 펌핑하여 복합가스 측정기(140)로 이송하는 역할을 수행한다. The pump 130 pumps the mixed gas flowing into the multi-manifold 120 from the plurality of suction hoses 110 and transfers the mixed gas to the multi-gas meter 140.

상기 복합가스 측정기(140)는 상기 펌프(130)의 작용으로 유입되는 산소 및 가연성 가스 등의 복합가스의 농도를 동시에 측정하는 역할을 수행한다. The multi-gas measuring instrument 140 simultaneously measures the concentration of the mixed gas such as oxygen and a combustible gas introduced through the action of the pump 130.

이하, 본 발명에 따른 밀폐구역내의 복합가스 멀티 측정시스템의 작용을 설명하기로 한다. Hereinafter, the operation of the multi-gas multi-measuring system in the closed zone according to the present invention will be described.

먼저, 여러 밀폐구역(A,B,C,D,E) 내에 각각 흡입호스(110)를 바닥에서 대략적으로 0.5m 높이에 고정 설치한 후 외부에 위치한 멀티 매니폴드(120)에 연결한다. First, the suction hose 110 is fixedly installed at a height of approximately 0.5m from the bottom in each of the various closed areas A, B, C, D, and E, and then connected to the external multi manifold 120.

그리고, 가스 측정을 원하는 해당 밀폐구역(A)의 복합가스만 유입될 수 있도록 멀티 매니폴드(120)에 부착된 해당 유입조절밸브(121)만을 개방하고, 그 이외의 다른 유입조절밸브(121)는 폐쇄한다. Then, only the inflow control valve 121 attached to the multi-manifold 120 is opened so that only the composite gas of the corresponding closed area A for gas measurement can be introduced therein, and other inflow control valves 121 other than that. Closes.

그리고, 펌프(130)를 작동시켜 흡입호스(110)에서 멀티 매니폴드(120)로 유입되는 밀폐구역(A)의 복합가스를 적당한 속도(예를 들면, 4L/min)로 펌핑한다. Then, the pump 130 is operated to pump the complex gas in the closed area A flowing into the multi-manifold 120 from the suction hose 110 at an appropriate speed (for example, 4 L / min).

그리고, 유량조절밸브(160)를 통해 가스 유량을 적절히 조절(예를 들면, 0.5L/min)하여 밀폐구역(A)의 복합가스가 복합 가스측정기(140)로 유입되도록 한다. Then, the gas flow rate is appropriately adjusted (for example, 0.5 L / min) through the flow control valve 160 to allow the composite gas in the closed area A to flow into the composite gas meter 140.

마지막으로, 복합 가스측정기(140)는 유입되는 복합가스에 포함된 산소 및 가연성 가스 등의 농도를 동시에 측정하게 되고, 측정된 산소 및 가연성 가스 등의 농도는 모니터(170)를 통해 디스플레이된다. Finally, the complex gas meter 140 simultaneously measures the concentrations of oxygen and flammable gas, etc., included in the incoming complex gas, and the measured concentrations of oxygen, combustible gas, etc. are displayed through the monitor 170.

이와 같이, 본 발명에 따른 밀폐구역내의 복합가스 멀티 측정시스템을 적용하게 되면, 작업자가 특정한 밀폐구역에 출입하기 전에 해당되는 밀폐구역 내부의 복합가스 농도를 외부에서 미리 측정한 후에 진입함으로써 가스에 의한 작업자의 안전사고를 미연에 방지할 수가 있게 된다. As described above, when the multi-gas multi-measurement system in the closed zone according to the present invention is applied, the operator enters after measuring the concentration of the mixed gas inside the corresponding closed zone in advance before entering or exiting a specific closed zone. The safety accident of the worker can be prevented in advance.

또한, 종래에는 밀폐구역 출입구마다 복합가스 측정기를 개별적으로 설치하였지만, 본 발명에 따른 복합가스 멀티 측정시스템의 경우 하나의 복합 가스측정기만으로 복수개소의 밀폐구역에 대한 복합가스 측정이 가능하고 복수개소의 밀폐구역을 통합하여 관리할 수가 있다. In addition, in the past, the composite gas measuring instrument was separately installed for each entrance to the closed area, but in the case of the multi-gas measuring system according to the present invention, the composite gas measuring system can be used for a plurality of closed areas with only one composite gas measuring device. Confined areas can be integrated and managed.
