The purposes of energy conservation and cost reduction for sea water desalination are achieved by means of a wind power and sea water heat self-exchange device of the wind-power sea water desalinizing device.
Description
Technical field: belong to wind-force sea water desaltination field.
Background technology:
Present desalination technology has reverse osmotic pressure " film " method and " heat " method of utilizing evaporating principle, and present popular is the low-temperature distillation method in " heat " method, promptly mainly is the low temperature multiple-effect distillation sea water desalting method.And the wind-force sea water desaltination is because wind-force only provides the auxiliary of sea water desaltination, vacuumizes etc. such as water pumping of the wind-force, wind-force heating, wind-force, so few people claim wind-force sea water distiling plant completely.
Summary of the invention:
A kind of wind-force sea water distiling plant belongs to pneumatic power sea water desaltination; At present the pneumatic power sea water distiling plant of popular comprises mainly that water pumping of the wind-force device, wind-force heating unit and wind-force vacuumize and carries out the low temperature distillation sea water desalination device; But wind-force is the supporting role; Left the by the use of thermal means of " embrane method " and low-temperature distillation, the wind-force sea water desaltination almost is luxurious what is said or talked about.
The application relates to a kind of without reverse osmosis membrane, without the low-temp low-pressure seawater wind-force desalting equipment of extra-heated, comprises the import and export of wind energy conversion system, evaporation of seawater chamber, condensing chamber, vacuum fan or vacuum pump, heat transfer tube and each several part.It is characterized in that condensing chamber below, have venting hole and liquid outlet orifice, condensing chamber is connected with the heat transfer tube internal cavity, and common open is in the steam inlet of system top; Evaporator room is positioned at the system top, and the heat transfer tube that is connected with the condensing chamber internal cavity outside is among the seawater of evaporator room, and the evaporator room cavity seals and be opened on the vapour outlet of system top; Steam inlet links to each other with vacuum fan or vacuum pump respectively with vapour outlet, and vacuum fan or vacuum pump link to each other with wind energy conversion system.
This device utilization wind-force and seawater self heat exchanger reach the purpose of utilizing wind energy to carry out sea water desaltination also can energy-conservation and reduction sea water desaltination cost.
Description of drawings
Embodiment
Once explain in conjunction with accompanying drawing:
Fig. 1 is a present specification system architecture synoptic diagram, and wherein evaporator room (5) is positioned at the top, and condensing chamber (1) is positioned at the below; Steam inlet (9) links to each other with heat transfer tube (6); Heat transfer tube (6) inner chamber links to each other with condensing chamber (1), and steam gets into heat transfer tube (6) by steam inlet (9) under the effect of vacuum fan (8), condenses under the seawater to make heat exchange effect of steam in evaporator room (5) in the heat transfer tube (6); Condensed water flows into condensing chamber (1) bottom storage, is discharged by liquid outlet (3) after reaching certain liquid level.Seawater in the evaporator room (5) is vaporization under low pressure under the effect of vacuum fan (8); And the heat of absorption seawater; Seawater temperature reduces, and seawater absorbs the heat that heat reduces owing to vaporization in order to compensation through the heat exchange with heat transfer tube (6), and the steam in the heat transfer tube (6) is through condensing with the heat exchange of the outer low temperature seawater of heat transfer tube (6); Form " fresh water ", this limneticum content is few.
Evaporator room (5) and condensing chamber (1) all need pressure bearing and seal; Wherein heat transfer tube (6) inner chamber can be regarded the part of condensing chamber as; What the heat transfer tube inner chamber played is the effect of condensing chamber, and heat transfer tube inner chamber and condensing chamber (1) are undivided in system, because heat transfer tube (6) inner chamber is less; Not being designated inner chamber " condensing chamber ", is the distinguishing feature of this heat-circulation type sea water desaltination but the heat transfer tube inner chamber has played " condensation " effect.
The effect of venting hole (4) is that beginning condensing chamber (1) is used for exhausted air when air content is higher.When operation is initial, need open exhausted air.
In order to improve velocity of evaporation; Can change constant-temperature evaporation; Such as being heated to the seawater in the vaporizer 60 degree Celsius, only need pressure seldom just can make the seawater explosive evaporatoin, so the vaporization temperature of seawater in can given vaporizer during sea water desaltination; For preventing the salt crystallization, can be controlled in initial temperature 70 and spend following, the following evaporation of operation circulating temperature 60 degree.
Because this type of sea water desaltination mode only need provide power to form negative pressure evaporation, so with wind-force power is provided.
In evaporator room, the injection of seawater or the discharge of strong brine, not expression in the Figure of description can add the outlet of sea intake and strong brine in real operation, but need when evaporation, keep sealing relatively.
Simplified summary: a kind of wind-force sea water distiling plant comprises the import and export of wind energy conversion system, evaporation of seawater chamber, condensing chamber, vacuum fan or vacuum pump, heat transfer tube and each several part.It is characterized in that condensing chamber below, have venting hole and liquid outlet orifice, condensing chamber is connected with the heat transfer tube internal cavity, and common open is in the steam inlet of system top; Evaporator room is positioned at the system top, and the heat transfer tube that is connected with the condensing chamber internal cavity outside is among the seawater of evaporator room, and the evaporator room cavity seals and be opened on the vapour outlet of system top; Steam inlet links to each other with vacuum fan or vacuum pump respectively with vapour outlet, and vacuum fan or vacuum pump link to each other with wind energy conversion system.
