In the sea water desalinating plant that the utility model provides, can also have such feature: wherein, water circulating pump is impeller pump.
The effect of utility model
Sea water desalinating plant involved by the utility model, because adopt Venturi tube to reduce the pressure of seawater water tank, so do not need extra heat source can realize liquid water molecules evaporation, is separated with seawater.The sea water desalinating plant that the utility model provides causes the change of pressure in device by Venturi tube, thus make Pressure Drop in seawater water tank to evaporation of water pressure under room temperature, water molecules absorbs heat generation flash distillation in sea water tank, water vapour enters the pure water water tank recycle system by Venturi tube, thus realizes the desalination of seawater.The sea water desalinating plant that the utility model provides, without the need to extra heat source, can at room temperature flash distillation, there is not the loss of equipment configuration yet.And, by the water in seawater and salt magazins' layout in the sea water desalinating plant that the utility model provides, not only obtain pure water, also obtain saline crystallization.In addition, seawater water tank is also convenient to disassembly, cleaning.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of embodiment sea water desalinating plant of the present utility model.
Embodiment
The technique means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, following examples are specifically addressed the utility model sea water desalinating plant by reference to the accompanying drawings.
Fig. 1 is the schematic diagram of sea water desalinating plant 100 in the present embodiment.
As shown in Figure 1, the present embodiment provides sea water desalinating plant 100 comprises and connecting successively: pure water water tank 1, seawater water tank 2, Venturi tube 3, water circulating pump 4 and heat exchanger 5.Pure water water tank 1 holds pure water.Venturi tube 3 one end is communicated with pure water water tank 1.Water circulating pump 4 is communicated with the other end of Venturi tube 3 flowing driving pure water.Heat exchanger 5 cools pure water, and one end is communicated with water circulating pump 4, and the other end is communicated with pure water water tank 1 bottom.Seawater water tank 2 holds seawater, and upper end is communicated with the tube neck of Venturi tube 3, and lower end is provided with seawater suction culvert.Seawater suction culvert import 7 is provided with valve.Water circulating pump 4 can adopt impeller pump.Impeller pump rotating speed can environmentally regulate, and then regulates the flow velocity of current in Venturi tube 3, thus obtains the evaporation of water pressure corresponding with room temperature.Heat exchanger 5 to can be in plate-type heat exchanger, tube and shell heat exchanger and double-pipe exchanger any one.Pure water water tank 1 can be wholely set with seawater water tank 2, also can be provided separately as required.Temperature in pure water water tank and seawater water tank is constant.
The sectional area of the tube neck of Venturi tube 3 significantly declines than Venturi tube other parts, and current are increased sharply at the flow velocity of venturi neck, and according to bernoulli principle, the increase of flow velocity causes the decline of static pressure.The tube neck of Venturi tube 3 is connected with seawater water tank 2, there is huge pressure difference in seawater water tank 2 with the tube neck of Venturi tube 3.Air in seawater water tank 2 is inhaled in Venturi tube 3, causes the pressure durations in seawater water tank 2 to decline.When evaporating pressure under pressure drops to the room temperature of water time, the evaporation that starts to absorb heat of the liquid water molecules in seawater becomes water vapour, and the concentration of seawater in seawater water tank 2 rises.The water vapour of evaporation is inhaled in Venturi tube 3 and collides with pure water current, and water vapour releasing heat becomes liquid water and mixes with current, and the temperature of pure water stream raises.Current enter heat exchanger after centrifugal water pump 4, in heat exchanger 5, carry out heat exchange with the seawater entered from seawater inlet port 7, and the temperature of pure water current declines, and the temperature of seawater current rises.Pure water enters pure water water tank, and add the water evaporated from seawater water tank in circulation, and make the liquid level of pure water water tank increase, flowed out by pure water water outlet 6, this also just achieves the desalination of seawater.Meanwhile, the seawater flowing through heat exchanger enters seawater water tank, supplements seawater, supplements the heat taken away because of water vapour evaporation in seawater water tank simultaneously.Do not consider thermosteresis and dissipation, the temperature in pure water water tank and seawater water tank is constant.Along with the operation of device, the concentration of seawater in seawater water tank constantly rises, until reach hypersaturated state, crystallize out in seawater water tank, carries out timing cleaning salt crystalloid, namely achieves being separated of water molecules and salt impurity.
The effect of embodiment and effect
Sea water desalinating plant involved by the utility model, because adopt Venturi tube to reduce the pressure of seawater water tank, so do not need extra heat source can realize liquid water molecules evaporation, is separated with seawater.The sea water desalinating plant that the utility model provides causes the change of pressure in device by Venturi tube, thus make Pressure Drop in seawater water tank to evaporation of water pressure under room temperature, water molecules absorbs heat generation flash distillation in sea water tank, water vapour enters the pure water water tank recycle system by Venturi tube, thus realizes the desalination of seawater.The sea water desalinating plant that the utility model provides, without the need to extra heat source, can at room temperature flash distillation, there is not the loss of equipment configuration yet.And, by the water in seawater and salt magazins' layout in the sea water desalinating plant that the utility model provides, not only obtain pure water, also obtain saline crystallization.In addition, seawater water tank is also convenient to disassembly, cleaning.
