在第1蒸發器10的蒸發室11a，例如，如搭載於船舶之柴油引擎主機關之套管冷卻水，可在現場使用的溫水是作為加熱用流體而從供給口11b供給，經過由擋板11d所形成之流路而從排出口11c排出。藉此，通過傳熱管14的海水被加熱而在傳熱管14內蒸發，導入至氣水分離室16c。 In the evaporating chamber 11a of the first evaporator 10, for example, the warm water that can be used on site is supplied from the supply port 11b as a heating fluid, and passes through the baffle. The flow path formed by the plate 11d is discharged from the discharge port 11c. Thereby, the seawater which passed the heat transfer tube 14 is heated, evaporates in the heat transfer tube 14, and is introduced into the gas-water separation chamber 16c.

導入至氣水分離室16c的蒸氣在混入之液滴被氣水分離板16d及除霧器16e分離後，從排水口16g排出而導入至第2蒸發器20的導入室24a，並通過傳熱管25的內部。在本實施形態中，由於除霧器16e是以殼體16的軸線L通過內部的方式呈水平配置於上下方向中央，因此可使除霧器16e的表面積最大化，可確實地去除液滴而提高造水效率。但是，除霧器16e的配置沒有特別限定，例如，亦可將除霧器16e配置於殼體16之軸線L較上方或下方。又，亦可以調整第1蒸發器10與第2蒸發器20之蒸發溫度差的目的，在排水口16g與導入口24b之間設置限流孔。 The steam introduced into the gas-water separation chamber 16c is discharged from the drain port 16g after the mixed liquid droplets are separated by the gas-water separation plate 16d and the demister 16e, and then introduced into the introduction chamber 24a of the second evaporator 20, and passed through the heat transfer chamber 24a. The inside of the tube 25. In this embodiment, since the demister 16e is arranged horizontally in the center in the vertical direction so that the axis L of the housing 16 passes through the inside, the surface area of the demister 16e can be maximized, and the liquid droplets can be reliably removed and Improve water production efficiency. However, the arrangement of the demister 16e is not particularly limited, for example, the demister 16e may be arranged above or below the axis L of the housing 16 . In addition, for the purpose of adjusting the evaporation temperature difference between the first evaporator 10 and the second evaporator 20, a restrictor hole may be provided between the drain port 16g and the inlet port 24b.

另一方面，氣水分離室16c內的蒸氣從排出口16f排出，而作為加熱用流體供給到第2蒸發器20的供給口21b後，經由擋板21d所形成的流路成為淡水，從排出口21c排出。藉此，通過傳熱管25之海水被加熱後在傳熱管25內蒸發，並導入至氣水分離室26c。 On the other hand, the steam in the gas-water separation chamber 16c is discharged from the discharge port 16f, and after being supplied to the supply port 21b of the second evaporator 20 as a heating fluid, it becomes fresh water through the flow path formed by the baffle plate 21d, and is discharged from the discharge port 16f. Outlet 21c discharges. Thereby, the seawater passing through the heat transfer tube 25 is heated, evaporates in the heat transfer tube 25, and is introduced into the gas-water separation chamber 26c.

導入氣水分離室26c的蒸氣在混入的液滴被氣水分離板26d及除霧器26e分離後，導入至凝結器30的凝結室31，並藉由通過凝結管32的海水而一部分凝結。如此，在第2段的蒸發器即第2蒸發器20所生成之蒸氣在凝結器30凝結而成為淡水。在凝結室31生成的淡水與從第2蒸發器20之排出口21c供給的淡水匯流，而藉由泵27的作動從回收口26h回收。 The steam introduced into the gas-water separation chamber 26c is introduced into the condensation chamber 31 of the condenser 30 after the mixed liquid droplets are separated by the gas-water separation plate 26d and the demister 26e, and is partially condensed by the seawater passing through the condensation pipe 32. In this way, the steam generated in the second evaporator, that is, the second evaporator 20 is condensed in the condenser 30 to become fresh water. The fresh water generated in the condensation chamber 31 merges with the fresh water supplied from the discharge port 21c of the second evaporator 20, and is recovered from the recovery port 26h by the operation of the pump 27.

在凝結室31未凝結的蒸氣及來自海水的不凝結性氣體從蒸氣排出口26f排出，然後與從排水口26g排出的海水一起被吸引到噴射器40的吸引口，並供給到凝結器30的凝結管32。 The steam that is not condensed in the condensation chamber 31 and the non-condensable gas from the seawater are discharged from the steam discharge port 26f, and then are sucked into the suction port of the ejector 40 together with the seawater discharged from the drain port 26g, and supplied to the condenser 30. Coagulation tube 32.

根據本實施形態之造水裝置1，第1蒸發器10及第2蒸發器20具備朝上下延伸之複數個傳熱管15、25，並且在水平方向上鄰接配置而構成雙重效用式之蒸發裝置，因此藉由小容量之緻密的構成，可得到高造水效率。因此，可適合使用作為船舶用等。 According to the water generation device 1 of the present embodiment, the first evaporator 10 and the second evaporator 20 are equipped with a plurality of heat transfer tubes 15 and 25 extending upward and downward, and are arranged adjacent to each other in the horizontal direction to form a double-effect evaporator. , Therefore, high water generation efficiency can be obtained through the compact structure of small capacity. Therefore, it can be suitably used for ships and the like.

又，第1蒸發器10及第2蒸發器20在容置傳熱管15、25的容器本體11、21的上方，具備有呈水平延伸之筒狀的殼體16、26，且殼體16、26之端部之間透過端板16b而連結，因此可容易地進行第1蒸發器10及第2蒸發器20的連接。 Moreover, the first evaporator 10 and the second evaporator 20 are equipped with cylindrical housings 16, 26 extending horizontally above the container bodies 11, 21 for accommodating the heat transfer tubes 15, 25, and the housing 16 , 26 are connected through the end plate 16b, so the connection between the first evaporator 10 and the second evaporator 20 can be easily performed.

第2蒸發器20及凝結器30的構成是與以往的單一效用式之船舶用造水裝置同樣，因此可利用例如形成於第2蒸發器20之殼體26之一端側的維修埠，而連接第1 蒸發器10。藉此，可將既有的單效用造水裝置容易改變成雙重效用式，故也可對應於增設等。 The structure of the second evaporator 20 and the condenser 30 is the same as that of a conventional single-effect marine water-making device, so they can be connected by using, for example, a maintenance port formed on one end side of the casing 26 of the second evaporator 20. No. 1 Evaporator 10. In this way, the existing single-effect water generating device can be easily changed to a double-effect type, so it can also correspond to expansion and the like.

以上，已就本發明之一實施形態詳述，但本發明之具體的態樣不限定於上述實施形態。例如，本實施形態之造水裝置1是作成雙重效用式，但可藉將具備與第1蒸發器10與同樣構成的1個或複數個蒸發器，隔著端板16a而在水平方向上依序連接，可容易地構成3重以上之多重效用造水裝置。因此，可有效率地進行因應於必要的造水量的設計及製造。 Above, one embodiment of the present invention has been described in detail, but specific aspects of the present invention are not limited to the above-mentioned embodiment. For example, the water-making device 1 of the present embodiment is made into a double-effect type, but it can be arranged in the horizontal direction by providing one or a plurality of evaporators having the same structure as the first evaporator 10, through the end plate 16a. Sequential connection can easily constitute more than three multi-function water-making devices. Therefore, it is possible to efficiently perform design and manufacture corresponding to the required amount of water production.
