Description
(1) technical field:
The utility model relates to the sea water desaltination field, and especially a kind of seawater last is imitated condenser.
(2) background technology:
Sea water desaltination claims sea water desalinization again, is the technology and the process of separating salt and water in the seawater.
Distillation method instant heating method is the desalination technology that adopts the earliest, is the topmost method of sea water desaltination.Distillation sea water desalting is with the seawater heating evaporation, makes vapor condensation obtain the process of fresh water again.
Multiple-effect evaporation is to allow the seawater after heating evaporate in a plurality of placed in-line vaporizers, the steam that previous evaporator evaporation is come out is as the thermal source of next vaporizer, and condensation becomes fresh water, this evaporation and condensation process repeat along each effect of a string vaporizer always, and every effect has all produced a considerable amount of distilled water.In the multiple-effect evaporation method, low temperature multiple-effect distillation (LT-MED) is one of method for saving energy in the distillation method.
The LT-MED sea water desalting equipment is imitated steam condenser, seawater pre-heaters by vaporizer, end.Vaporizer is one group of parallel horizontal evaporating tube, and steam is input to generating tube inside, manages outer sprayed sea water and evaporates.The seawater pre-heaters is that the part secondary steam that use device end effect produces comes the primary heater unit water inlet, makes it temperature near the temperature of controlling in the last evaporator.It then is to utilize seawater or other water sources with unnecessary end effect secondary steam condensation that steam condenser is imitated at the end.
At present, condenser is imitated at LT-MED sea water desalting equipment end and the seawater pre-heaters generally has two kinds of schemes, and the one, separately make two interchanger, the scheme that charging seawater and water of condensation enter different devices respectively, abbreviation scheme one; Perhaps make a unified interchanger, all by pretreated seawater condensation, the charging seawater enters vaporizer, the scheme of unnecessary seawater discharging, abbreviation scheme two.There is following problem respectively in these two kinds of schemes:
1, scheme one must be placed around last evaporator vaporizer symmetry, for the vaporizer that contains relatively independent two or more generating tube tank nests, is difficult for symmetry and places;
2, for two interchanger, steam must enter with the pipeline of identical resistance in two interchanger, otherwise steam distribution can be affected;
3, making two interchanger manufactured materials, manufacturing expense, calorific loss all can be bigger;
4, imitating condensers for scheme two end must be with identical material manufacturing, and heat transfer tube must all adopt titanium pipes or other high erosion-resisting tubing, installation cost increase;
5, an interchanger must all adopt pretreated seawater condensation, increases the burden of sea water preprocessing, causes waste.
(3) utility model content:
The purpose of this utility model is to provide a kind of seawater last to imitate condenser, and it can effectively solve the deficiencies in the prior art, and has simplified equipment layout and circuit design, has reduced cost.
The technical solution of the utility model: a kind of seawater last is imitated condenser, it is characterized in that it is made of housing, charging seawater to make heat exchange pipe, water coolant heat transfer tube, tube sheet and central dividing plate, wherein said case top has the import of end effect secondary steam, and there is the charging sea intake both sides; Said tube sheet is connected in the housing; Said charging seawater to make heat exchange pipe and water coolant heat transfer tube are connected on the tube sheet, and have central dividing plate to isolate between charging seawater to make heat exchange pipe and the water coolant heat transfer tube; Said charging seawater to make heat exchange pipe constitutes the seawater preheating device, and its feed-water end connects the charging sea intake, and the water side connects the charging seawer outlet; Said water coolant heat transfer tube constitutes condenser, and its feed-water end connects entrance of cooling water, and the water side connects cooling water outlet.
Above-mentioned said seawater to make heat exchange pipe is designed to one way or more than two journeys, comprises two journeys, three journeys or quadruple pass more than two journeys.
Above-mentioned said water coolant heat exchange tube design becomes one way or more than two journeys, comprises two journeys, three journeys or quadruple pass more than two journeys.
Above-mentioned said water coolant is simply dealt seawater or other water sources.
Working process of the present utility model is: (1) end effect secondary steam enters the shell side that condenser shell is imitated at the end by import; (2) the charging seawater enters the tube side of charging seawater to make heat exchange pipe by the charging sea intake, is discharged by the charging seawer outlet after the preheating; (3) water coolant enters the tube side of water coolant heat transfer tube by entrance of cooling water, and is discharged by cooling water outlet behind the steam heat-shift; (4) steam then by the water yield in two portions heat transfer tube and water temperature control, freely distributes in housing; (5) charging seawater in the charging seawater to make heat exchange pipe tube side and the water coolant in the water coolant heat transfer tube tube side are heated by the steam of shell side respectively, and the vapor condensation of shell side becomes fresh water simultaneously.
Superiority of the present utility model is: 1, seawater preheating device and condenser are produced in the housing, the unified supply of steam can not exist pipe resistance different and cause the phenomenon of steam distribution inequality, and equipment layout and circuit design have all been oversimplified; 2 and heat transfer tube is divided into relatively independent two portions, a part is used for the preheating of charging seawater, and a part is used for the condensation of residual steam, can select simply dealt seawater as water coolant, alleviates the burden of sea water preprocessing, reduces the pre-treatment cost; 3, water coolant can also be selected other water sources according to practical situation, reduces equipment corrosion; 4, seawater preheating device and condenser are produced in the housing, and heat transfer tube is divided into relatively independent two portions, can selects different tubing for use, reduce cost according to different quality; 5, according to different demands, two portions heat transfer tube can also be made the heat transfer tube of different lengths, different tube diameters, and can make the heat-exchanging tube bundle of different quantities, different tube sides, realizes design and the handiness of making.
