Specific embodiment
For further illustrating that the present invention is to reach technological means and the work(that predetermined goal of the invention is taken
Effect, below in conjunction with accompanying drawing and preferred embodiment, to according to its tool of double latent membrane component proposed by the present invention
Body embodiment, step, structure, feature and its effect describe in detail.
The invention mainly relates to following technical terms.
Membrane Materials: form gas-liquid interface using microporous filter membrane, carry out liquid evaporation and hardly possible by picking to move
The detached process of volatile substance.
Hydrophobic membrane silk: a kind of hollow fiber film thread, by special material and technique, so that film is presented thin
Aqueouss, aqueous water will not pass through, and steam can pass through, and realizes Membrane Materials process.
Sensible heat: liquid is raised and lowered the heat exchanging during temperature, such as every kilogram of water is raised and lowered 1
The sensible heat exchanging when spending is 4.2kj.
Latent heat: the heat that exchanges when liquid evaporation or steam condensation, both under equal conditions quantity phases
With.The latent heat of every kilogram of water evaporation is 2300kj, is 550 times about of sensible heat, that is, want to steam
Sending out one kilogram of water needs 550 kilograms of water once to reduce, or 55 kilograms of water reduce by 10 degree, or condensation one
Kilogram of steam.
Double latent membrane component: a kind of membrane module structure, hollow fiber film thread is seated in metal tube,
The quantity of film silk depends on the circumstances, and this kind of metal tube is seated in putamina, and metal tube quantity is optionally
Depending on, sleeve pipe is formed by metal tube and film silk, the film that metal tube forms the structure of array in putamina steams
Evaporate assembly.
It has been investigated that, existing film distillation technology is all the heat transfer type of " sensible heat-latent heat-sensible heat ".As
Flow in capillary-pipe film hot strong brine, by the cooling of itself, provides heat to pass through to flashing to steam
Film, steam is come and is contacted cold metal tube between capillary-pipe film and metal tube and be cooled into water, and metal
Cooling water between pipe and putamina will take away these heats by the intensification of itself；Prior art be all by
The Condensation of Membrane Materials process is integrated with feed liquid warm or material liquid heating process, in fact
Membrane Materials process has completed, and is not effectively combined with condensation process, either inside membrane module also
It is outside membrane module, all cannot effectively carry out energy utilization.A large amount of latent heat of condensation are used for preheating,
Cannot high efficiente callback, since it is desired that substantial amounts of cold burden liquid sensible heat receives the latent of this some vapor condensation
Heat.In addition, required a large amount of latent heat during the evaporation of Membrane Materials are only by the hot material liquid itself of external heat
Temperature drop sensible heat provide, same inefficiency.This technical method is not latent with condensation by evaporation latent heat
Heat effectively combines, and efficiency is low, be its cannot industrial applications basic reason.
To illustrate below by Theoretical Calculation to adopt " sensible heat using the handling process ratio of " latent heat-latent heat "
The handling process of latent heat sensible heat " has higher efficiency.
" sensible heat latent heat sensible heat " handling process theory aquifer yield:
If 70 DEG C of the 1kg/h that flows in capillary-pipe film of strong brine；Vacuum is 0.08mpa, temperature
It is zero that degree drops to 60 DEG C of flux, does not consider the resistance of film itself, 4.2kj/kg* DEG C of the specific heat of water, water
The average 2300kj/kg of heat of vaporization, then the theoretical maximum aquifer yield of system be:
4.2kj/kg* DEG C of * 1kg/h* (70 DEG C -60 DEG C)/2300kj/kg=0.018kg/h
" latent heat latent heat " handling process theory aquifer yield:
If 70 DEG C of the 1kg/h that flows between hydrophobic membrane silk and metal tube of strong brine；Vacuum
0.08mpa, in this method, strong brine temperature will not reduce, and does not consider the resistance of film itself, the vapour of water
Change the average 2300kj/kg of heat, then the theoretical maximum aquifer yield of system is:
2300kj/kg*1kg/h/2300kj/kg=1kg/h
In sum, the limit theory efficiency ratios of two methods are " sensible heats for " latent heat latent heat "
55.5 times of latent heat sensible heat ", the aquifer yield in practice as the reduction film of temperature can drastically decline,
So overall efficiency ratio meeting gap is bigger.
In the process of " sensible heat latent heat sensible heat ", strong brine temperature fall after membrane module
Low it is necessary to heat again, need heat to be [4.2kj/kg* DEG C of * 1kg/h* (70 DEG C -60 DEG C)]=42
kj/h；Cooling water has been taken away heat by the intensification of itself and also will have been discharged, but the temperature of cooling water is too low,
So in the air substantially can only be discharged to.In the process of " latent heat latent heat ", strong brine passes through
After membrane module, temperature is not changed in it is not necessary to extra heat；Origin of heat is the new life of membrane component
The condensation of indirect steam provides, so the demand also very little to cooling water, is discharged to the heat of in the air waste
Amount is also very little.The performance study of film has been able to obtain the larger film of aquifer yield at present, but should
Use assembly, in system when very low with regard to efficiency, main cause is exactly that " sensible heat latent heat shows
