Description
(1) technical field
The utility model relates to a kind of novel multi-effect distillation seawater desalinating device of multi-stage type condenser.Belong to field of sea water desalting technology.
(2) background technology
Along with the raising of sustainable development of economy and living standards of the people, people are increasing to the demand of fresh water, and are more and more higher to requirements in water quality, and the deficiency of water resources, distribution is unequal, make the water resources imbalance between supply and demand of original anxiety more sharp-pointed.Low temperature multiple-effect distillation sea water desalting device in the desalination technology is to adopt heat energy system water, and the quality height of system water has vast potential for future development.
Effect distillation seawater desalinating device of multi is to drive by repeatedly evaporation and condensation with a certain amount of working steam, thereby obtains being multiple times than the condensed water of heating steam amount.The multiple-effect distillation sea water desalting condenser is used for the secondary steam that the condensation last evaporator produces, and promotes the temperature of evaporation feed liquor seawater simultaneously.Because the load of condenser is bigger, the seawater part after the intensification enters the sea as water coolant, and another part adds behind the Scale inhibitors as vaporizer distillatory charging seawater.As Fig. 1 is the quadruple effect distillation seawater desalinating device, and it is made of 1st effective evaporator 3,2nd effect evaporator 6, triple-effect evaporator 7, quadruple effect evaporator 8, condenser 12, sea intake 13, cooled with seawater water relief outlet 14, sea intake arm 16 etc.
The water generation ratio of effect distillation seawater desalinating device of multi and cost are directly related with the temperature difference first, last evaporator at present, and the temperature difference is big more, imitate many water generation ratios of number height, and it is low that unit makes water yield cost.Because first evaporator is subjected to the influence of factors such as seawater fouling, corrosion, the generally high evaporation temperature of seawater can not be above 70 ℃.The temperature difference that strengthens head, last evaporator must reduce condensing temperature, condensing temperature is subjected to the charging seawater to go out the restriction of condenser temperature, it is high 2～4 ℃ to go out condenser temperature than charging seawater, because the charging seawater is limited by natural condition, summer seawater medial temperature generally about 25～35 ℃, seawater enters vaporizer after condenser heat exchange temperature raises.Condensing temperature is reduced be restricted,, then can reduce condensing temperature, increase the temperature difference if improve the seawater amount that unit makes the water yield, but charging seawater water intake system and delivery system increasing, initial cost and running cost improve.How do not improving under the prerequisite of charging seawater amount that unit makes the water yield, by reducing condensing temperature and then strengthen total temperature difference first, last evaporator, and then improving water generation ratio, reducing running cost and material cost and become the present problem that solves of needing.
(3) summary of the invention
The purpose of this utility model is to solve above-mentioned deficiency, provides a kind of not improving under the prerequisite of charging seawater amount that unit makes the water yield, can strengthen novel multi-effect distillation seawater desalinating device of multi-stage type condenser first, the last evaporator total temperature difference.
The purpose of this utility model is achieved in that a kind of novel multi-effect distillation seawater desalinating device of multi-stage type condenser, comprise vaporizer, condenser, the working steam import, working steam coagulates water out, the concentrated seawater connecting leg, the fresh water connecting leg condenses, the concentrated seawater overboard pump, fresh water discharge pump, secondary steam advances condenser tube, sea intake, cooled with seawater water relief outlet, non-condensable gases relief outlet and sea intake arm, described condenser is divided into 1,2,3 ... the N section, every section condenser is an individual cavity, the seawater series connection enters N, N-1,2,1 section condenser, described vaporizer is to increase the N-1 single-effect evaporator corresponding with N section condenser on original M single-effect evaporator basis, the secondary steam that former M single-effect evaporator comes out is divided into two the tunnel, parallel connection enters the 1st and imitates condenser and M+1 single-effect evaporator, and the like, the secondary steam that last M+N-1 single-effect evaporator comes out enters N and imitates condenser.
The beneficial effects of the utility model are:
The restriction that condensing temperature mainly is subjected to the charging seawater to go out condenser temperature, it is high 2～4 ℃ to go out condenser temperature than charging seawater, because effect distillation seawater desalinating device of multi is lower by the seawater temperature rise of condenser, generally all above more than 10 ℃.Be divided into 1 by the condenser that will finish whole seawater temperature rise originally, 2,3 ... the N section, the seawater series connection enters N, N-1,2,1 section condenser, general every section seawater temperature rise is at 3～5 ℃, make it become N section condenser, make the 1st section condenser identical by this kind mode with original system, condensing temperature in other each section condensers reduces successively, vaporizer is imitated at original M increases the N-1 single-effect evaporator corresponding with N section condenser on the basis, former M is imitated out the secondary steam that directly enters condenser and is divided into two the tunnel, and parallel connection enters the 1st effect condenser and adds hot feed seawater and M+1 single-effect evaporator heating tube off-lying sea water generates secondary steam.And the like, the secondary steam that last M+N-1 single-effect evaporator comes out enters N and imitates condenser.By the segmentation setting of condenser, make full use of the thermograde of charging seawater in condenser, reduced condensing temperature, strengthened total temperature difference first, last evaporator.By above scheme, unit makes under the constant prerequisite of the charging seawater amount of the water yield, has improved water generation ratio, has increased and has made the water yield, reduces running cost.Strengthen the heat transfer temperature difference of vaporizer by the condensing temperature gradient of control segmentation condenser, reduce the heat transfer area that unit makes the vaporizer of the water yield, save material cost, reduce initial cost.
