Description
Technical field
The utility model relates to a kind of seawater desalination system.
Background technology
On boats and ships, sea water desalinating plant is process pre-treatment earlier at present, and dosing utilizes the jacket water of diesel engine to heat again, realize the desalination effect thereby flash to water vapour, but preprocessing process makes system complex, increases cost.Pretreated words are carried out in not dosing, and when seawater evaporated at comparatively high temps, meeting fouling on vaporizing coil caused heat exchange efficiency to descend.
The utility model content
The purpose of this utility model is to propose a kind of seawater desalination system, described seawater desalination system can make evaporation of seawater at a lower temperature, and does not need the sea water preprocessing system, to solve present seawater desalination system complexity, manufacturing, operation cost height, the problem of easy fouling on the generating tube.
The utility model solves the problems of the technologies described above by the following technical programs:
Seawater desalination system is characterized in that:
Comprise the condenser of condensed steam and pre-hot sea water, with the vaporizer of the evaporation of seawater of preheating, the resorber of the solution that absorbs water vapour is housed and will have absorbed the producer that the solution of water vapour evaporates once more;
Also comprise the seawater suction culvert and the fresh water outlet pipeline that are connected with described condenser; Connect described condenser, described vaporizer, described resorber, described producer successively, connect the sea water desaltination pipeline of described condenser again, the sea water desaltination pipeline between wherein said resorber and the described producer is provided with pump; Jacket water suction culvert that is connected with described producer and jacket water outlet pipeline.
Further, also comprise the hot and cold working medium circulation line that connects described vaporizer and described resorber, described hot and cold working medium circulation line is provided with pump.Like this, just the energy utilization with described resorber and described vaporizer has connected, and wherein the pump of She Zhiing provides power for the circulation of hot and cold working medium.
Further, also comprise the pipeline of the solution of described absorption water vapour being carried back described resorber from described producer that connects described producer and described resorber.So just realized absorbing the circulation of the solution of water vapour.
The solution of described absorption water vapour is lithium-bromide solution.Also can for other absorb water vapour preferably, be applicable to the solution of sea water desaltination.
The utility model is compared with conventional boats and ships seawater desalination system, has the following advantages:
1, seawater evaporates at a lower temperature, can effectively stop fouling of evaporator, improves the efficient of system;
2, omit preprocessing process, reached the requirement that simplified system improves economy.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Seawater desalination system, comprise the condenser 2 of condensed steam and pre-hot sea water, with the vaporizer 3 of the evaporation of seawater of preheating, the resorber 4 of bromize lithium concentrated solution is housed and will have absorbed the producer 5 that the bromize lithium dilute solution of water vapour evaporates once more.
Sea water desaltination pipeline 5 connects condenser 2, vaporizer 3, resorber 4, producer 1 successively, connects condenser 2 again.Wherein the sea water desaltination pipeline 5 between resorber 4 and the producer 1 is provided with pump 6.Also be provided with the pipeline 7 of bromize lithium concentrated solution being carried back resorber 4 from producer 1 between producer 1 and the resorber 4.
Jacket water suction culvert 8 is connected with producer 1 with jacket water outlet pipeline 9.Jacket water flows out producers 1 from jacket water outlet pipeline 9 then from having absorbed the solution heating evaporation of water vapour after jacket water suction culvert 8 enters producer 1.
Hot and cold working medium circulation line 12,13 connects vaporizer 3 and resorber 4, and hot and cold working medium circulation line is provided with pump 14.
Principle of work of the present utility model is as follows: seawater enters condenser 2 from seawater water inlet pipe 10, and seawater is preheated in condenser 2 simultaneously, and water vapour is condensed into pure water (pure water is derived from the fresh water rising pipe).The seawater that is preheated enters vaporizer 3 from condenser 2, enters resorber 4 after being evaporated into water vapour on the hot coil (not shown) of spray in vaporizer 3.Water vapour mixes with bromize lithium concentrated solution from producer 1 in resorber 4, be cooled to bromize lithium dilute solution and send into producer 1 (because dense lithiumbromide has the intensive absorptivity to water vapour by pump 6, so in resorber 4, absorbed rapidly from the water vapour of vaporizer 3, build-up of pressure descends, and transfers to resorber 4 for water vapour from vaporizer 3 power is provided).The dilute solution that enters producer 1 is sprayed, by jacket water once more heating evaporation obtain the water vapour of higher degree, send into condenser 2 coolings.
The round-robin effect of hot and cold working medium provides heat for the low-temperature evaporation of seawater in the vaporizer 3 on the one hand, provides cold for resorber 4 on the other hand.So the circulation of hot and cold working medium is that the transfer of heat energy of resorber 4 is become the latent heat of water to vaporizer 3 in essence, reaches the purpose that energy shifts.The working medium of using in the circulation of hot and cold working medium is water or freonll-11.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
