And, without the need to water generating unit 32 is remained air-tight state, thus the simplification of the structure of water generating unit 32 can be realized.Further, by reducing number of components, the cost that can realize motor driven operator 10 reduces.

In addition, owing to not needing drawdown pump, therefore, even if when generating water purification from the former water in river etc., the engaging-in switch-valves such as the silt contained in former water 29 (being located at the valve of the upstream side of drawdown pump) also can be prevented and causes motor driven operator 10 fault.Thereby, it is possible to improve the performance of motor driven operator 10, thus water purification 69 can be generated rightly.

At this, be provided with multiple cooling fins 81 at the outside surface 76a at top 76 and the local of periphery wall 77.Therefore, the area opposed with air (outside 68) of condenser 38 is guaranteed larger.Thereby, it is possible to utilize multiple cooling fins 81 to carry out heat exchange efficiently, thus condenser 38 is remained the suitable state of cooling.

In addition, in the internal surface 76b at top 76, be provided with multiple right condensation fin 82 at right condensation position (condensation position) 76d of container for evaporation 51 (the 3rd wall portion 57) top, and be provided with multiple left condensation fin 84 at left condensation position (condensation position) 76e of container for evaporation 51 (the 1st wall portion 55) top.Therefore, multiple right condensation fin 82 and multiple left condensation fin 84 are retained as the suitable state of cooling by multiple cooling fins 81.

Thus, by the water vapour that imports from vaporizer 35 in condenser 38 by contacting with multiple right condensation fin 82 or multiple left condensation fin 84 and condense, and be attached on each condensation fin 82,84 as water purification 69.That is, condenser 38 is located at the top of vaporizer 35, the steam coagulation utilizing right condensation position 76d and left condensation position 76e to make to evaporate in vaporizer 35 and generate water purification.

In addition, right condensation position 76d is positioned near open aperture 78.Therefore, multiple right condensation fin 82 is arranged near open aperture 78 in the inside of condenser 38, and forms labyrinth structure 83.Therefore, import the water vapour in condenser 38, cooled and condense in labyrinth structure 83 towards the water vapour of open aperture 78 from vaporizer 35.Thereby, it is possible to reliably prevent the water vapour imported in condenser 38 from flowing out to outside 68 from open aperture 78.

Further, open aperture 78 is arranged on distance gas take-in portion 66 position farthest.In gas take-in portion 66, the waste heat of waste gas is retained as the highest temperature.Therefore, the former water 29 be accumulated in former water storagetank 48 is evaporated in a large number at " position near the gas take-in portion 66 in heating part 53 ".By making open aperture 78 apart from former water 29 by the position of evaporating in a large number farthest, thereby, it is possible to the distance that a large amount of water vapour arrives till open aperture 78 is guaranteed longer.Therefore, it is possible to make the water vapour in importing condenser 38 condense efficiently before arrival open aperture 78.Thereby, it is possible to more reliably prevent water vapour from flowing out to outside 68 from open aperture 78.

The water purification generated in condenser 38 is collected by separator 39.Separator 39, between vaporizer 35 and condenser 38, is formed with opening portion 88 at the central 39a of separator 39.By forming opening portion 88 on separator 39, thus, the water vapour evaporated in vaporizer 35 is directed in condenser 38 via opening portion 88.
