Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
A kind of humidification and condensation integrating device as Figure 1-3 comprises blast inlet 1, humidifying chamber 2, condensing chamber 3, reservoir chamber 4, air outlet 5 and shell 7.Humidifying chamber 2 and condensing chamber 3 are confined chambers of air, can bear certain blast and air does not leak.Separate by dividing plate 8 between humidifying chamber 2 and the condensing chamber 3, dividing plate 8 is provided with hole 9, so dividing plate 8 has been communicated with humidifying chamber 2 and condensing chamber 3, has also played the orderly mobile effect of air of organizing.During concrete enforcement, the hole 9 on the dividing plate 8 can be located at any position, preferably is located at the middle part of dividing plate 8.Reservoir chamber 4 can be arranged on any position of described humidification and condensation device all-in-one inside, considers that from the composition optimizes aspect reservoir chamber 4 preferably is arranged on the foot of described humidification and condensation integrating device device.Place heated seawater or brackish water in the reservoir chamber 4.For better utilised sun power, described blast inlet 1 links to each other with air collector, and blast inlet 1 can also link to each other with other used heat when specifically implementing.
Shown in Fig. 1 and 2, the input terminus that humidifying chamber 2 is positioned at air links to each other with blast inlet 1.Air enters humidifying chamber 2 by blast inlet 1, and the top by the humidification module 11 that is equipped with in the humidifying chamber 2 and humidification module 11 is provided with spray equipment air is strengthened humidification.Wherein, humidification module 11 is to be made of evaporating wet-film humidifying material.Described spray equipment comprises the water pump that is arranged in the described reservoir chamber 4, the pipeline 13 that links to each other with water pump, the spray line 12 that links to each other with pipeline 13, and described spray line 12 is located at the top of described humidification module 11.For the spray effect that obtains, spray line 12 is arranged in the top of described humidification module 11 uniformly.As preferably, water pump is anticorrosion water pump 10 in this example.During concrete enforcement, described spray equipment can also be to include only water pump and pipeline, offers spray apertures in described pipeline and humidification module 11 relative positions.
Shown in Fig. 1 and 3, the output terminal that condensing chamber 3 is positioned at air links to each other with air outlet 5, and air flows out from condensing chamber 3 by air outlet 5, and condensing chamber 3 also is the output chamber of fresh water.Mainly be to play condensation by pipe finned cooler 14 in the condensing chamber 3, pipe finned cooler 14 water inlet taps 15 faucets 16 are by shell 7 and stretch out.Arranged beneath water-accepting basin 17 at pipe finned cooler 14.
As shown in Figure 1,, can play the insulation promoter action to humidification in the humidifying chamber 2 on the one hand, can prevent that on the other hand fresh water from also not entering condensing chamber 3 and just separating out too early, thermal insulation layer 6 is set in the middle of the housing of described shell 7 in order to reach good heat insulation effect.Thermal insulation layer 6 generally is made of the thick lagging material of 30mm ~ 50mm, specifically humidifying chamber 2, condensing chamber 3 and reservoir chamber 4 is played insulation effect.
In this enforcement, seawater or brackish water desalination process are such: be stored in the reservoir chamber 4 by the seawater of sun power or waste heating or brackish water, seawater that temperature is higher or brackish water, general seawater or brackish water temperature are at 40 ℃～70 ℃, entered spray line 12 by anticorrosion water pump 10 sucking-offs, be sprayed on the humidification module 11 then uniformly, air is forced input and is carried out a large amount of damp and hot exchanges through humidification module 11 by inlet mouth 1, air is reinforced humidification in process of flowing, form humid tropical condition.Humid tropical condition air admission condensing chamber 3 then, seawater that temperature is lower or brackish water enter in pipe finned cooler 14 runners, and hot and humid air is reached dew-point temperature by cooling, and fresh water can be separated out, and the desalination water of separating out is collected in the water-accepting basin 17.Thereby realized the desalination process of seawater or brackish water.Finish the process of the transfer of fresh water from water to the air when wherein, air is through humidifying chamber 2.Specifically be through humidification, the evaporation of the fresh water in seawater or the brackish water has been incorporated air, promptly the moisture in seawater or the brackish water has incorporated in the air after having become gaseous state by liquid state, and it is big that the humidity of air becomes, and carried moisture.In this process, behind seawater or brackish water spray, the portion water in the seawater (being fresh water) evaporation has entered air, and all also in the water of spray, promptly salinity is always in the seawater or brackish water of reservoir chamber for salinity.When salt concentration greater than after to a certain degree, bleed off and change seawater or brackish water, seawater that more renews or brackish water just can continue to have obtained fresh water.
Humidification and condensation integrating device of the present invention need not to adopt the operating structure of vacuum pump, therefore it is simple in structure, volume is little, be convenient to safeguard, and this all-in-one need not to move under vacuum state, normal pressure promptly can normally move, and is not high to equipment and operating requirement, can combined solar thermal source or used heat thermal source, front-end investment is little, and market outlook are wide.
The present invention also provides a kind of method for desalting seawater that is used for described humidification and condensation integrating device, specifically operates according to following steps:
Thereby realized the desalination of seawater or brackish water, so whole process flow is simple and easy to operate.
Above-described embodiment, the present invention embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacing all should be included in protection scope of the present invention.
