Evaporator the second evaporator 20 generate steam by condenser 30 condense and become fresh water.In the fresh water that condensation chamber 31 generates
Collaborate with the fresh water supplied from the outlet 21c of the second evaporator 20, is recycled by the running of pump 27 from recovery port 26h.
It will be arranged from the non-condensing gas for the steam and seawater not condensed in condensation chamber 31 from steam outlet 26f
Out, with the suction port that is attracted to injector 40 together with the seawater that discharge outlet 26g is discharged, it is supplied to the condenser pipe of condenser 30
32。
According to the fresh water generator 1 of present embodiment, the first evaporator 10 and the second evaporator 20 are more with extending up and down
A heat conducting pipe 15,25 and the vaporising device for being configured adjacently and constituting double effect type in the horizontal direction, therefore utilize little Rong
The cramped construction of amount can obtain Gao Zaoshui efficiency.Therefore, ship etc. can be suitable for.
In addition, the first evaporator 10 and the second evaporator 20 are in the top of the container body 11,21 of storage heat conducting pipe 15,25
Cabinet 16,26 with horizontal-extending tubular, the end of cabinet 16,26 is connected to each other via end plate 16b, therefore can be easy
The connection of ground progress the first evaporator 10 and the second evaporator 20.
The structure of second evaporator 20 and condenser 30 is identical as existing single ship fresh water generator of effect type, because
This, such as can utilize and connect in the maintenance port of the one end formation of the cabinet 26 of the second evaporator 20 and the first evaporator 10
It connects.Thereby, it is possible to answer fresh water generator to be readily changed to double effect type existing single-action, therefore also copes with and add
Deng.
More than, it is described in detail in one embodiment of the present invention, but specific mode of the invention is not limited to
State embodiment.For example, the fresh water generator 1 of present embodiment is double effect type, but by that will have and the first evaporator
One or more evaporator of 10 identical structures is sequentially connected in the horizontal direction via end plate 16a, can be easily configured
Triple above multiple-effect fresh water generators.Therefore, efficiently it can make water according to required and be designed and manufacture.
