Description
Technical field
The present invention relates to a kind of degree of depth energy conservation sea water desalting apparatus, belong to desalinization and energy-saving and emission-reduction field.
Background technology
Along with economic fast development, human living standard improves constantly, and water resource is as a kind of basic resource,
Become the Vital Strategic Problems of restriction socio-economic development.Especially in China, China's water resource per capita only has 2100m3, only generation
The 28% of boundary's average level；Only Beijing water resources consumption level in 2012 exceeds the 70% of total supply, and water resource deficiency is
Increasingly become the bottleneck of China's high speed development.As a kind of stable and unrestricted fresh water supply approach, desalinization
It it is one of method of most prospect solving natural fresh water resource shortage.Full-boiled process seawater desalinization pretreatment is simple, and maintenance cycle is long,
But conventional full-boiled process desalinization exchanges fresh water to consume high-grade energy for for cost, and thermal source cost makes desalinating cost very
High.It is to solve desalination technology to be difficult to the primary of spread that the method utilizing innovation reduces energy consumption problem in desalinization
Problem.Desalinization combines controlling the water circulation with energy-intensive industries, and utilizing low-grade low temperature exhaust heat is full-boiled process desalinization for thermal source
The direction of technology development, possesses the advantage that single desalination technology is incomparable.
Low-grade heat source and then minimizing full-boiled process desalinization heat consumption cost is utilized to have the newest method, such as low-temperature multi-effect
Technology, it can utilize as little as it is crucial that the utilization of the use of multistage multiple-effect and low-grade steam greatly reduces thermal source cost
Water producing cost, as desalinization thermal source, is fallen below 6-8 yuan/ton, but the developing direction of this technology is ton by 70 DEG C of steam
Ultra-large controlling the water circulation is the highest to ton water cost in small-scale engineering.Another kind of method, such as capillary force actuation techniques, this skill
Art, with metal powder sintered porous body as evaporating surface, utilizes capillary force to evaporating surface moisturizing, decreases conventional art sea water and supplement
The use of kinetic pump, reduce the temperature of desalinization, the thermal source of available as little as 33 DEG C simultaneously.But typical capillary force
Desalination technology is driven to have a fatal inferior position, it is simply that vaporizer uses metal solid-phase sintering technology, and the method is with high costs, high temperature
Sintering process is complicated, and another significant problem existed is that running later stage fouling crystallization blocks evaporating surface, and difficulty is cleaned, it may be said that
Solid-phase sintering porous evaporation face be system properly functioning in a bottleneck problem being difficult to avoid that.Number of patent application:
201510892409.3, it is proposed that a kind of desalinization processing means, utilize REFRIGERATION SYSTEM DRIVEN BY CAPILLARY FORCE to realize low temperature seawater desalination, vaporizer
Using conventional rib-type solid sintered porous bodies, there is steam channel in vaporizer, reduces heat exchange area, if it is desired to extensive
Producing water, whole device is the hugest；Additionally use fin heat conduction capillary wick, increase thermal conduction resistance, hinder heat exchange；Simultaneously rib with
Capillary materials needs to be in close contact (Interference contact), the highest to the flatness requirement on rib surface and capillary wick evaporating surface, precision
Need to control at 0.1 micron so that the program is limited in laboratory scale always and uses.Big in order to solve fin thermal conduction resistance, flat
Whole degree requires the problem that height limits large-scale application.Number of patent application: 201510850716.5, it is proposed that a kind of REFRIGERATION SYSTEM DRIVEN BY CAPILLARY FORCE sea
Water desalination vaporizer, vaporization chamber uses flat integrated solid phase sintering porous body, solves fin thermal conduction resistance big, flatness
Require a high difficult problem, but still suffering from heat-transfer surface cost in a fatal problem large-scale application is Conventional cryogenic multiple-effect sea water
10-50 times of desalinating cost, cost is the highest；More seriously solid-phase sintering makes device in running, and salinity exists
Top layer or internal crystallization, easily block porous body, and capillary layer fouling crystallization is difficult to process, and cleaning problem is difficult to solve；It addition,
When vaporization chamber fixed gas is too much or steam generation rate is too fast, porous body and sea water side can be caused to separate, cause porous body
Cannot the problem of imbibition.
Capillary method desalination technology decreases thermal source cost to a certain extent to the use of low-temperature heat source, but the utilization of low heat
Mean that this technology is difficult to low-temperature multi-effect technology the same, energy consumption cost is greatly lowered by recycling steam condensation heat.
Because 33 DEG C of thermals source are the most sufficiently small to the heat transfer temperature difference of sea water, it is impossible to be arranged to multistage condensation heat be recycled.Although it is logical
The method crossing mechanical compress can solve the problem that this problem, but mechanical compress is electric power input, and power cost is high, and it directly increases
Desalinating cost, is not suitable for the popularization and application of the capillary method desalination technology that the leading low-temperature heat source degree of depth recycles very much.Mesh
The absorption pressurization cycle of front existence is a kind of typical raise steam device, and it defeats vapour method relative to traditional mechanical electric
Decrease the acting of high-grade electric energy, it is possible to use low temperature heat energy carries out steam pressurized circulation.But in today that the energy is the most in short supply,
Vigorously advocate Absorption heat-transformer under the background of energy-saving and emission-reduction and be still a highly energy-consuming process, define the application of the method,
If the energy consumption input of absorption pressurized circulation process can be reduced further, to advancing absorption compression system by certain means
Application has great innovative significance.Such as number of patent application: 201310024546.6, it is proposed that a kind of solar airconditioning desalinization system
System, carries out steam pressurization, replaces traditional mechanical compression, uses low-temperature multi-effect simultaneously, improves energy utilization rate；But this system is many
Place needs booster, needs to consume more high-order electric energy, does not possess degree of depth power savings advantages.
