Technical field
The present invention relates to a kind of low temperature multiple-effect distillation sea water desalting evaporimeter multitubular bundles arrangement, belong to low temperature multiple-effect distillation sea water desalting technical field.
Background technology
From current economy, technical conditions and water resource supply and demand situation; for coastal economy developed regions; development desalination technology, wants fresh water to be the effective way that coastal state and area solve freshwater resources imbalance between supply and demand to ocean, be also the inexorable trend that coastal cities solve fresh water crisis.
Last decade, along with the progress of technology and the raising of unit scale, low temperature multiple-effect distillation sea water desalting device enters Rapid development stage.This advantage such as mainly to have heat transfer efficiency high due to low temperature multiple-effect distillation sea water desalting device, and product water water quality is good, and load regulation range is large, and operating temperature is low, and fouling corrosion tendency is little, has become the second generation hot method desalinization mainstream technology.The maximization low temperature multiple-effect distillation sea water desalting device be combined with power plant will be economic one of water-electricity cogeneration technical method reliably, be hot method desalinization developing direction.It is the necessary condition realizing maximization low temperature multiple-effect distillation sea water desalting application of installation that evaporimeter inner multi-pipe bundle is arranged.Existing low temperature multiple-effect distillation sea water desalting device adopts single tube bundle designs usually, if still adopt single tube bundle designs in large-scale low-temperature multi-effect distillation seawater desalinating device, two large problems will be faced: 1) to evaporate the indirect steam of generation outward larger in single tube interfascicular flow resistance for seawater pipe, cause steam can not proper flow, the performance of evaporimeter cannot be ensured; 2) single tube bundle designs can not the inner space of Appropriate application evaporimeter, causes evaporator shell diameter and tubesheet dimension to become large, increases material cost and the manufacturing cost of sea water desalinating unit.
Summary of the invention
Technical problem to be solved by this invention be existing single tube beam evaporation device structure for large-scale low-temperature multi-effect distillation seawater desalinating device time, can cause interbank indirect steam cannot proper flow and the problem such as device materials and manufacturing cost increase.
In order to solve the problem, technical scheme of the present invention proposes a kind of low-temperature multiple-effect seawater desalination evaporator multitubular bundles arrangement, it is characterized in that, comprises housing, be provided with the tube bank that at least two groups connect side by side in housing, the both sides, front and back often organizing tube bank are respectively equipped with front tube sheet, back tube sheet; Both sides, front and back between two adjacent groups tube bank and between outermost tube bank and housing are respectively equipped with front tube sheet shrouding, back tube sheet shrouding.
Preferably, described housing is cylinder or cube.
Preferably, dividing plate and supporting construction is provided with in described tube bank.
Preferably, described dividing plate and supporting construction are made up of gripper shoe equally distributed between front tube sheet and back tube sheet.
Preferably, often organize between described front tube sheet shrouding and back tube sheet shrouding and form steam flow channel, be provided with equally distributed demister from top to bottom in this steam flow channel, the downside of each demister is provided with one piece of deflector.
Preferably, described demister is silk screen.
Preferably, often organize in described tube bank and be provided with spray equipment.
The multitubular bundles arrangement of a kind of low temperature multiple-effect distillation sea water desalting evaporimeter provided by the invention, namely in single effect evaporator, arranges multi units tube bundle, restrains and be supported in housing by front/rear tube sheet shrouding, front/rear tube sheet, dividing plate and gripper shoe etc.Often organize tube bank and configure independently spray system, leave corresponding steam channel between tube bank group, and configure deflector and silk screen demister carries out salt solution drop separation to indirect steam.
The present invention, by arranging at evaporimeter inner multi-pipe bundle, achieves the maximization of low temperature multiple-effect distillation sea water desalting device.Compared with prior art, the present invention has the following advantages:
1) adopt multitubular bundles to arrange, drag losses when indirect steam flows through tube bank can be reduced, ensure proper flow and the efficient heat transfer of indirect steam;
2) adopt multitubular bundles to arrange, better can adjust the appearance and size of each tube bank, ensure the seawater spraying effect that heat exchanger tube is good outward, improve heat transfer efficiency;
3) adopt multitubular bundles to arrange, tube bank can be controlled within the scope of certain size, thus reduce housing and the tubesheet dimension of evaporimeter, reduce evaporimeter cost of raw and processing and manufacturing cost;
4) adopt multitubular bundles to arrange, effectively can regulate the profile of each tube bank, make its housing of more fitting, make full use of inner space, reduce the floor space of sea water desalinating unit.
