In ships and offshore structures, a fresh water generator is indispensable for the production of fresh water, which is generally necessary for boiler feed, equipment cleaning and cooling, ballast water treatment, and domestic water.

The fresh water generator is divided into low pressure evaporation type and reverse osmosis type which are used to make the fresh water required from the ship by using seawater. In most commercial ships, Jacket Water, which is the waste heat of the engine, Low-pressure evaporative water cleaners are mostly used.

The fresh water generator supplies seawater to a vacuum-formed container, and when the main engine coolant and heat are heated, the seawater evaporates and the distilled water is condensed.

The fresh water generator uses the water supplied from the ejector pump to condense the evaporated seawater passing through the condenser and to condense the condensed water.

In order to control the performance of the ejector according to seawater temperature, it is common to attach a valve to the air suction line so that the amount of air suction But it is difficult to control.

According to the present invention having the above-described configuration, the following effects can be expected.

Depending on the temperature of the seawater, a number of non-condensable gas lines connected from the condenser to the ejector can be installed to adjust the suction amount of the non-condensable gas sucked according to the position of the nozzle inside the ejector.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an illustration of an example of a water conditioner capable of adjusting the amount of unconcentrated gas suction according to an embodiment of the present invention. FIG.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an exemplary view of a water purifier capable of adjusting the amount of unconcentrated gas suction according to an embodiment of the present invention.

Referring to FIG. 1, the fresh water generator capable of adjusting the non-condensed gas suction amount according to the present invention includes an ejector 100 for introducing seawater and having a nozzle 120 formed therein to form a vacuum, seawater introduced into the ejector, And a condenser 300 connected to the heater to cool the evaporated seawater to cool the seawater. The water heater 400 includes a temperature sensor 400 and a noncondensing gas line 500 and a controller 600 to adjust the amount of non-condensable gas in the condenser according to the temperature of the seawater.

First, the ejector 100 is formed in a trumpet shape, and has an inlet 112 through which fluid is introduced into one side and an outlet 114 through which fluid is discharged from the other side. A vacuum chamber is formed by the nozzle 120 inside.

The nozzle 120 is installed in the ejector 100 and is disposed at an inlet 112 through which the fluid flows into the nozzle 120. The nozzle 120 has a smaller cross sectional area toward the end of the nozzle 120 The speed of the fluid is increased and the pressure is lowered.

Since the degree of vacuum is raised by the nozzle 120 to supply the seawater to the heater 200, the seawater can be evaporated at a low temperature.

The seawater decompressed by the ejector 100 is heated by the heater 200, condensed by the condenser 300, and supplied with clean water.

At this time, when the vessel is traveling in the polar region, the temperature of the sea water is low and the sea water of the equatorial region is relatively high. The temperature deviation will be about 30 占 폚.

In general, when the low temperature seawater is introduced, the degree of vacuum is well formed in the ejector, so that the amount of the steam is increased due to the increase of the heat transfer area in the condenser. However, Is reduced, but scale generation is reduced.

Therefore, it is necessary to adjust the amount of noncondensing gas so that the heat transfer area inside the condenser 300 can be adjusted.

The temperature sensor 400 measures the temperature of the seawater flowing into the ejector.

The non-condensing gas line 500 is connected between the ejector 100 and the condenser 300 to discharge the condensed gas in the condenser 300 to the ejector 100.

A plurality of nozzles 120 are connected to the outer circumferential surface of one side of the ejector at positions corresponding to the longitudinal direction of the ejector so as to vary the amount of suction depending on the difference in distance from the outlet of the nozzle 120.

The non-condensing gas line 500 includes a first line 520 formed near the outlet of the nozzle 120 at a longitudinal center point of the nozzle 120 and a second line 520 extending in the longitudinal direction of the nozzle 120. And a second line (540) formed near the inlet side of the nozzle (120) at a center point.

The controller 600 receives the seawater temperature value of the temperature sensor 400 installed in the non-condensing gas line 500 and compares it with the temperature value set in the controller 600 so that one of the non- And can be programmed to open by a valve to adjust the heat transfer area of the condenser.

More specifically, the first line 520 is opened when the temperature is higher than the set temperature, and the second line 540 is opened when the temperature is lower than the set temperature.

That is, when the temperature of the fluid as the seawater is high, the first line 520 is opened to increase the inflow amount of the non-condensed gas. When the temperature of the fluid is low, the second line 540 opens, Less.

As described above, it can be seen that the present invention is based on the basic technical idea to provide a fresh water generator capable of adjusting the amount of unconcentrated gas suction, and within the scope of the basic idea of the present invention, Of course, many other variations are possible for those who have.
