Technical field
The present invention relates to technical field of heat exchange devices, more particularly to a kind of board-like seawater desalination system liquid distributor.
Background technology
Traditional falling film evaporator is mostly tubular structure, and liquid distributor is located above steam-generating bank, by the liquid of liquid distributor
State working medium is formed on the outside of evaporator tube bank and uniform liquid film and is flowed downward, restrained with evaporator in flow process in medium into
Row heat exchange undergoes phase transition evaporation, has the characteristics that heat transfer coefficient is high, heat transfer temperature difference is small and working medium filling quantity is few.With shell
Formula heat exchanger is compared, and plate heat exchanger has space small, the big feature of the coefficient of heat transfer, with the development of technology,
The certain fields that shell-and-tube heat exchanger rules all the land, plate heat exchanger gradually starts to substitute shell-and-tube heat exchanger, and is playing
The effect of bigger.
In field of seawater desalination, board-like low temperature multi-effect seawater desalting system still belongs to new things, and Zhejiang University is for board-like
Two patents of low temperature multi-effect seawater desalting system application, but there is no embodiment, the exploitativeness of patent waits to evaluate；Country
Ocean sea water desalination research institute of office successful tests tonne seawater desalination system, is commonly called as " fresh water generator ", but scale is smaller,
Use must not be popularized.
Desalination plant in the prior art is falling film type structure, and falling film evaporation is affected by gravity, therefore
Falling liquid film method evaporating heat exchanger is restricted in the more serious applications of the fluctuation such as ship situation.
Invention content
The present invention for falling film evaporator in the prior art liquid distributor there are the problem of, a kind of strong applicability is provided,
Small by environmental fluctuating, cloth liquid is uniform, and form a film stable board-like seawater desalination system liquid distributor.
The object of the present invention is achieved like this, and a kind of board-like seawater desalination system liquid distributor includes the heat exchange of closed assembly
Plate forms Medium Exchange chamber between adjacent heat exchange plate, and being sticked respectively in the opposing sidewalls of the adjacent heat exchange plate, there have to be close
Seal strip, the opposite face lower part of the sealing joint strip is opposite to be equipped with card slot, is clamped in the card slot and is equipped with porous metal plate, described
Foam metal layer is equipped between sealing joint strip on the upside of porous metal plate, the sealing joint strip on the upside of the porous metal plate is equipped with
The drain micropore extended outward is additionally provided with the drain fabric with drain microporous connectivity between the heat exchange plate and sealing joint strip
Layer.
In the board-like seawater desalination system liquid distributor of the present invention, the foam metal layer and micropore metal that are arranged between sealing joint strip
Plate has filtering and purification function to seawater, and the capillary force that microcellular structure generates can overcome gravity to have the influence of liquid
Bob-weight force effect still can guarantee that cloth liquid is uniform, does not influence the uniformity and stabilization of seawater cloth liquid and film forming in non-vertical state
Property；Medium Exchange intracavitary, seawater contact foam metal layer from top to bottom, and uniform cloth liquid, seawater exist in foam metal sheaf space
It is contacted with drain tissue layer by drain micropore under the constraint of porous metal plate, drain fabric is full of under the action of capillary force
Layer, drain tissue layer have certain thickness, and drain tissue layer is adsorbed with heat exchange plate under the action of water, make in seawater pressure
Reach supersaturation with lower drain fabric absorption water, supersaturation water is under the collective effect of surface tension and capillary force in heat exchanger plate
Piece surface homogeneous film formation.The membrane formation mechanism film forming thickness is uniform and stable, avoids the appearance of the dry situation in part, can effectively ensure that
The normal work of evaporator, especially capillary force form a film, and are not influenced by gravitation, it is ensured that extremely by seawater desalination system application extension
In the marine system that use environment vibration is jolted.
For ease of improving the stress intensity of porous metal plate, the porous metal plate and foam metal layer are in being bent up
Arc.
For ease of drain, the drain micropore is from the Inside To Outside of sealing joint strip in angled downward from horizontal.
It forms a film for ease of uniform cloth liquid, drain tissue layer lower part exceeds sealing joint strip lower end.
As a preference of the present invention, the material of the foam metal layer and porous metal plate is stainless steel.
