물 이송을 위한 더블 배관용 전기히터{electric heater for double pipe of currenting water}Electric heater for double pipe of currenting water for water transfer

본 발명은 물 이송을 위한 더블 배관용 전기히터에 관한 것으로, 보다 상세하게는 일정한 유속을 갖는 물이 소정의 구간을 통과하면서 순간적으로 가열되는 가열공간을 복수 개가 동시에 이루어지도록 하여 하나의 구조에서 동시에 개별적으로 각기 다른 요구조건에 알맞게 제공할 수 있도록 한 물 이송을 위한 더블 배관용 전기히터에 관한 것이다.The present invention relates to an electric heater for double piping for water transport, and more particularly, a plurality of heating spaces in which water having a constant flow rate is instantaneously heated while passing through a predetermined section is made simultaneously in one structure. It relates to electric heaters for double piping for water transfer, which can be individually tailored to different requirements.

일반적으로 물을 가열하는 전기히터는 전기보일러에 사용되는 것으로, 전원을 받아 고온으로 가열되는 히터봉에 의해 접촉된 물이 점진적으로 가열되어 고온상태로 유지하도록 한다.In general, electric heaters for heating water are used in electric boilers, and water in contact with a heater rod heated to a high temperature by receiving power is gradually heated to maintain a high temperature state.

그런데 이와 같은 전기히터의 히터봉은 350℃이상의 고온으로 가열되어야 접촉된 물을 가열시킬 수 있기 때문에 열손실이 높아 물 가열에 상당한 시간이 걸리고, 전기손실이 많아 전기소비가 많고, 이에 따라 히터봉의 열원체에 의해 간접적으로 가열하는 방식이므로 효율이 낮고 운전 및 관리비용이 많이 소요되는 문제점이 있다.However, since the heater rod of such an electric heater must be heated to a high temperature of 350°C or higher to heat the contact water, the heat loss is high, so it takes a considerable time to heat the water, and the electricity consumption is large due to the large amount of electricity loss. Since it is a method of heating indirectly by an element, there are problems in that efficiency is low and operation and management costs are high.

또한, 히터봉은 물을 가열하면서 점진적으로 이물질이 부착되어 열 전달율이 낮아져 효율이 더 낮아지거나, 교체하여야 하는 문제점과, 교체에 따른 관리비용이 많이 소요되는 문제점이 있다.In addition, while heating water, foreign substances are gradually attached to the heater rod, thereby lowering the heat transfer rate and thus lowering the efficiency, or there is a problem in that it needs to be replaced, and there is a problem in that the replacement costs a lot of maintenance.

또한, 가열된 물을 필요한 요구장소에게로 이송하게 될 경우, 이송되는 도중에 열손실이 발생하여 요구되는 온도를 맞추기 어렵거나, 가열되는 물을 수용하는 탱크가 필요하고, 항상 가열된 상태를 유지하여야 하기 때문에 운전 및 관리비용이 많이 소요되는 문제점이 있다.In addition, when the heated water is transferred to a required place, heat loss occurs during the transfer, so it is difficult to meet the required temperature, or a tank containing the heated water is required, and the heated state must be maintained at all times. Therefore, there is a problem in that the operation and management cost is high.
