Description
Technical field
The present invention relates generally to a kind of liquid evaporating technology, is filled more particularly to that need not make the liquid evaporation of liquid boiling
It puts and technique, is mainly used in chemical industry and water treatment field.
Background technology
So-called evaporation refers to mixing liquid to be separated heating (or taking decompression measure simultaneously) drawing life to boiling
Into steam and condensation obtain condensate liquid, remaining liq is the concentrates different from former mixing liquid.It is evaporated to last can be achieved
The separation of the solid matter of liquid and dissolving in a liquid.The main points of evaporation technology：First, to maintain the temperature and pressure of material
It is typically that material is made accomplished continuously or intermittently to boil in certain range；Second is that steam is discharged from evaporator in time so that steam
Send out saturated vapour pressure of the vapour pressure in device less than the material solvent under operating condition；Third, to prevent the entrainment with steam ejected
Liquid.
For needing to be evaporated liquid material (such as seawater and waste water) concentration or making its crystallization therein so as to extract
The occasion of dissolved solid, currently used method are to heat the liquid its boiling point or take decompression measure simultaneously, make its boiling
It rises, it, in the process can be by cold so as to obtain the crystalline solid (such as concentrated seawater or concentration waste water) of concentrate or dissolved solid
The mode of solidifying steam obtains condensate liquid (such as condensed water or distilled water/fresh water) and recycles a part of heat.Specific evaporation technology
There are liquid film evaporation technique, flash process, vacuum flashing technique and multiple-effect evaporation technique etc., corresponding equipment includes climbing-film evaporation
Device, falling film evaporator, flash distillation plant, vacuum flashing device etc..
In evaporation technology is boiled in traditional adding, in order to maintain the lasting progress of evaporation, liquid material needs constantly pass through heat
Exchanger exchanges heat to keep higher temperature.With the progress of evaporation, liquid material constantly concentrates, until solute is just after saturated solution
Start to be precipitated.Due to hot-spot on the heat-transfer area of heat exchanger, being more easy to precipitation solute leads to fouling on heat-transfer area, so as to cause
Heat transfer efficiency drastically reduces, to maintain to evaporate frequent shutdown progress maintenance clean of having to.In order to improve heat transfer efficiency and delay
Adverse effect caused by fouling, some occasions use multiple-effect evaporation technique, but this causes increasing considerably for equipment investment again.Make
For special example, water as the various solution or mixed liquor of solvent or carrier evaporation and concentration (as pollutant concentration is very high
Waste water), just it is faced with above-mentioned problem.
In addition, occasion existing for having heat mutability substance in not having corresponding heat source or liquid to be evaporated, does not permit
Perhaps material is heated very high temperature.Low-temperature evaporation technique will be used in these cases, i.e., in the temperature less than boiling point of liquid
Evaporation of the solvent is made to obtain concentrate or crystal under degree, the most commonly used is low-temperature reduced-pressure evaporations.Vacuum flashing technique is that low-temperature reduced-pressure steams
One kind of technique is sent out, refers to maintain evaporimeter internal pressure not higher than the saturated vapour pressure of liquid under operation temperature, so as to make liquid
Material boiling evaporates purpose to reach very fast.Although maintaining negative pressure that can realize rapid evaporation at a lower temperature, tie up
The energy consumption for holding negative pressure is very big, and the cost of equipment is also high.
Do not make the evaporation technology energy consumption that material boils relatively low, but evaporation efficiency is also low, be in particular in that atmospheric low-temperature evaporates
Evaporation capacity of the device in unit interval unit volume is extremely low.To reach the evaporation effect identical with other evaporation technologies, normal pressure is low
Warm evaporation technology need to manufacture evaporator it is very huge, equipment and place investment greatly increase.
To improve atmospheric low-temperature evaporation efficiency, it is common practice to increase gas-liquid interface contact area and gas phase flow velocity, it is cold
But tower is exactly to be designed according to such thinking.It is promoted at the top of tall and big cooling tower using pump handle water, then sprayed in tower
Filler on, water flow through from top to bottom under gravity packing layer and the surface of filler formed liquid film.At the top of cooling tower
Fan is installed and carries out exhausting, air is made the gap (channel) in filler to be passed through to flow from bottom to top entrainment of vapor, solution
It is achieved that cooling and a degree of concentration.But the evaporator of cooling tower form cannot be used for material concentration or crystallization,
Because with the progress of evaporation, solution is continuously available concentration, and viscosity is increasing, and the pump energy consumption of circulation conveying material is very big very
To so that the pumping of material becomes not realizing, and the temperature of material is also difficult to maintain.

The advantages such as short, efficient and equipment investment is low.
In conclusion the advantages of embodiment of the present invention and good effect are as follows：
(1) disk type designs, and the liquid film surface area that evaporator unit volume interior energy is formed is big, therefore equipment evaporation efficiency
It is high.In addition, simple in equipment, easy to manufacture, equipment investment expense are low.

It closes.The liquid vaporising unit of the embodiment of the present invention cannot be only used for evaporating, concentrate and crystallizing, can also simultaneously recycling design.
About this point, it is explained in detail below.Traditional cooling tower is divided into have a filler and two kinds of non-filling, the former is heat
Water pump, which is promoted to the top of cooling tower, is distributed spray to the top of filler, and hot water trickles from top to bottom in the gap of filler,
Air then flows, that is, form convective motion from bottom to top under the action of the wind turbine of tower top, and gas takes away the moisture of evaporation
So that remaining water is cooled down；The latter is also by pump handle hot water distribution spray to tower top, is poured down as raining in torrents, empty
Gas then flows from bottom to top under the fan action of tower top, is equally to take away moisture water is made to cool down.Theoretically, such operation
Process it is also possible that the liquid water stayed is concentrated, but on Practical Project not used for cooling tower in such purposes
's.The reason is that the cooling tower of filler is because filler is fixed filling, and piling height is usually all higher (in order to abundant
Utilize the unsaturation humidity of air), the cost that the solid after crystallization/fouling in packing layer can not be cleared up or be cleared up is too big.Not yet
The cooling tower for having filler evaporates moisture by the specific surface area of water droplet, and less efficient and small water droplet can be raised air-flow band
It walks solute is caused to lose.Two kinds of cooling towers are not that its evaporation efficiency is low for concentrating/crystallizing another main cause in place,
A small amount of moisture is evaporated so that liquid water temperature drop low ten is easily able to spend, but several times or more than ten times of liquid concentration
(for example 10 times of concentration just needs 90% moisture evaporation for being equivalent to initial liquid weight to fall), needs most of moisture to steam
Hair falls, and just too big with equipment volume if cooling tower, cost is too big.But cooling tower simple structure, it can be built into
The structures (cooling tower of such as power plant is all tens meters of height) of the huge scale of construction, than the recirculated cooling water for being more suitable for big flow
Cooling is handled.
(4) working gas can be natural air or the air by preheating or be by dry sky
Gas.
(5) under conditions of having heat source, it is made to maintain to close in addition to warm operation gas can also heat liquid material simultaneously

(6) crystallization/fouling occurs mainly on disc (the especially situation of heated working gas), to heat transfer efficiency
Influence small, post processing is simple, energy-saving.
(7) liquid material can maintain relatively low temperature, disclosure satisfy that the needs of some special occasions, for example utilize waste heat
Handle the situation of waste water or due to the situation for not allowing high temperature in liquid containing special composition.
This is described by taking preparing fresh in brine concentration, salt water crystallization, seawater and wastewater zero discharge process as an example individually below
The application example of invention.
Application examples one：The concentration of strong brine
The application example belongs to the most basic application of the present invention, is simplest application mode.As shown in Figure 4, low temperature steams
Transmitting apparatus is only configured with most basic corollary equipment --- driving mechanism 3 and wind turbine 4.Wind turbine 4 is placed in low-temperature evaporation dress in this example
The gas feed side put, the air outlet of wind turbine 4 are connected with the gas feed 103 of low-temperature evaporation device.In this example, strong brine
Liquid-inlet 101 through low-temperature evaporation device injects low-temperature evaporation device and is stored in the lower part of its housing 1, forms certain liquid
Position.Its liquid level is the lower part to the lower edge position close to rotation axis 201 for flooding disc 202 in this example.Start driving machine
Structure 3, the rate rotation that the rotor 2 of low-temperature evaporation device has been previously set, its rotating speed is 1~30 rev/min in this example.
Subsequent start-up wind turbine 4, air be blown into gas feed 103 and be distributed to by flow deflector rotor 2 disc 202 gas into
Mouth side, air-flow pass through the gap of disc 202 and the surface of purged disc, are then discharged via the gas vent of opposite side 104
Low-temperature evaporation device is simultaneously diffused into air.In this process, since the outer surface of disc 202 is hydrophilic, with dense
The contact of brine one is i.e. wetted and forms liquid film in its outer surface.With the rotation of rotor 2, strong brine has wet whole discs
All outer surfaces are simultaneously covered with liquid film on it.The rotation of rotor is with causing the different parts cycle alternation of disc 202 with strong brine
Contact is then by gas flow purging.Disc 202 does not evaporate its liquid film then by the part that strong brine floods under the purging of air-flow
In partial moisture, salinity is then retained in remaining liquid film.With the progress of evaporation process, disc 202 incessantly from
Part strong brine is taken away in strong brine in the form of liquid film, partial moisture is then evaporated under the purging of air-flow, then salinity
The strong brine or the salt grain of partially crystallizable that concentration becomes larger are taken back in the strong brine of 1 lower part of housing storage, and the disc 202 of rotation is again
It takes away strong brine ... this process to thicken slightly to continue, strong brine will constantly dry out, the concentration of salinity
Increasing, i.e., brine is concentrated.To the concentration or cycles of concentration of concentration brine that control finally obtains, only need to maintain to evaporate
The ratio between the increment of brine and the discharge capacity of concentration brine, the benefit of brine are controlled under the premise of liquid level is constant in device
To discharge capacity=cycles of concentration of amount/concentration brine.
In the application examples, the evaporation efficiency of liquid vaporising unit is influenced by operating condition.Air is drier, temperature more
Height, the more big then evaporation efficiency of air velocity are higher.Therefore the most basic application be liquid vaporising unit efficiency it is lower should

Device 5.Treat that each equipment reaches the spray flow that steady operational status can adjust spray equipment 7 later so that the bottom of housing 1
Slightly hydrops, to have given play to the evaporability of low-temperature evaporation device as much as possible.The hydrops of 1 bottom of housing can be via its bottom
Emptying rate of liquid mouth 105 discharges low-temperature evaporation device and is sent to the container or pipeline that strong brine is supplied for spray equipment 7, obtains it
Circulating and evaporating.Control it is proper if, the bottom of housing 1 does not have substantially or seldom hydrops, spray of the strong brine on disc 202 at this time
Leaching rate substantially obtains balance with its evaporation rate, and moisture is substantially all to be evaporated, and salinity is then crystallized in the outer of disc 202
On surface.The salinity for treating to crystallize on disc 202 reaches certain thickness, should shut down, and takes measures that solid salinity is allowed to be detached from disc
202 surface is so as to be collected, and then cryogenic vaporizer can come into operation again.
The operating principle of the application example with process is with application examples 1, difference is for purging disc outer surface
Air-flow is the air by preheating, it is hereby achieved that higher evaporation efficiency, an equal amount of low-temperature evaporation device can be sent out
Shoot the evaporability of bigger.
