Problems solved by technology

[0005] However, in the above-mentioned conventional plate-type water generating device, the heat exchange efficiency between the seawater raw material and hot water introduced into the heater 50 is insufficient, so as a result, a large heat transfer area is required, resulting in an increase in the size of the heat transfer plate.

Abstract

A plate type water making apparatus including heater (10) for heating raw seawater by hot water to thereby produce steam and condenser (30) for cooling the produced steam by cooling water to thereby produce distilled water, characterized by further including preheating means (40) for heating portion of cooling water discharged from the condenser (30) so as to introduce the same in the heater (10) as raw seawater. In this plate type water making apparatus, heating evaporation of raw seawater can be efficiently performed, so that there can be attained downsizing and cost reduction.

Description

technical field [0001] The present invention relates to a plate type water generating device, in more detail, relates to a plate type water generating device which utilizes a plate type heat exchanger to perform evaporation of seawater raw materials and condensation of steam. Background technique [0002] As a conventional plate-type fresh water generating device, for example, the configuration disclosed in Patent Document 1 is known. Such as Figure 7 As shown, the above-mentioned plate-type water generating device has: the seawater raw material introduced from the raw water inlet 53 is heated and evaporated by hot water used for cooling the engine of the ship, and then discharged from the raw material discharge port; The evaporator 60 for evaporating liquid droplets in the water vapor discharged from the heater 50; condenser 70. [0003] Both the heater 50 and the condenser 70 are plate heat exchangers configured in such a way that high-temperature gas and low-temperatur...
