Description of drawings
Fig. 1 is structural representation of the present invention, comprises desalination tank internal structure.
Fig. 2 is side-view of the present invention.
Wherein: the 1-ship's machinery, 2-machine cooling water pipeline, 3-desalinates tank, 4-suction culvert, 5-outlet pipeline, 6-seawater water inlet pipe, 7-seawater rising pipe, 8-condenser, 9-fresh-water tank, 10-fresh water line, 11-salt sub sensor, 12-flow valve.
Embodiment
Below in conjunction with specific embodiments and the drawings, further set forth the present invention.
As shown in Figure 1, a kind of new marine desalination equipment for design, comprise ship's machinery, machine cooling water pipeline and desalination tank, described machine cooling water pipeline comprises suction culvert and outlet pipeline, described outlet pipeline enters from one side entrance, desalination tank below, pass from the outlet of desalination tank opposite side, the part of described outlet pipeline in the desalination tank adopts vertically repeatedly bending, be increased in the length of pipe in the desalination tank, the below of described desalination tank also comprises seawater entrance and seawer outlet, top in the described desalination tank is condenser, condenser is set to the low middle high arc in two ends, be provided with fresh-water tank below the condenser two ends, described fresh-water tank connects fresh water line and water suction pump; The outlet pipeline of described machine cooling water pipeline out passes the pre-heating device afterwards from the desalination tank, seawater is flowed through and is entered the desalination tank by the seawater entrance behind the pre-heating device of built-in outlet pipeline, after the outlet pipeline of described machine cooling water pipeline passes the pre-heating device, link to each other with the suction culvert of machine cooling water pipeline.
The part of described outlet pipeline in the desalination tank can be arranged to vertically continuous S shape bending, perhaps is arranged to the vertically continuous square waveform bending of being arranged to shown in the accompanying drawing 1.So can lengthen pipeline in the length of desalination in the tank, make that about 23 seawater of spending normal tempss fully contact in hot water and the desalination tank of about 67-87 degree of the cooling machine that flows out in the machine in the outlet pipeline, thereby can carry out sufficient heat exchange.The part of bending can be arranged to uniform interval.The seawater of below is through sufficient heat exchange in the desalination tank, reaches i.e. volatilization behind the 47 degree boiling points, through desalination tank inner condenser condensation and flow to fresh-water tank, pumpedly again goes out.And through the hot water in the outlet pipeline that flows out after the heat exchange 47 degree are arranged still, therefore design walks to form preheating apparatus from the seawater water inlet pipe, pending seawater is preheated, thereby take full advantage of the heat of the hot water in the outlet pipeline, can also make the heat exchange of seawater more abundant.And since seawater and hot water always the keeper flow, and the suction of the outer water pump of fresh-water tank can make desalination tank maritime interior waters top keep certain vacuum pressure levels, is conducive to the evaporation of seawater, thereby guarantees the efficient of desalination.
Described fresh-water tank is outer can also to be connected to the salt sub sensor, described outlet pipeline is provided with variable valve passing desalination tank place, the seawaterline that the seawer outlet of described desalination tank connects is provided with flow valve, in the data that receive the salt sub sensor or after reporting to the police, can be according to the Data Control variable valve of salt sub sensor and the aperture of flow valve, thereby control the thermal evaporation process that is subjected to of seawater, obtain satisfactory fresh water.
The heat that marine desalination equipment of the present invention utilizes the ship's machinery running to produce repeatedly fully, the heat that utilizes the machine water coolant to take away carries out preheating and fully exchange to seawater, evaporation obtains fresh water, and the device design is succinct, easy for installation, utilize and lengthen the purpose that pipeline reaches abundant heat exchange, equipment can also be according to the size of ship, the requirement of fresh water comes the size of setting device, and suitable multiple ship type reaches both easy to install, the excellent results of energy-conserving and environment-protective again, also reduce cost, the fresh water treatment ability of ocean boat is strengthened greatly, no longer be limited by the restriction of various device.
The thermal source of apparatus of the present invention also can utilize the used heat of boiler in fact, even the heat of solar water heater etc., the work that the desalination tank in collocation apparatus of the present invention and primary heater unit just can be finished sea water desaltination.
