Description
Technical field
The present invention relates to wastewater treatment, the side of zero discharge treatment and reuse is evaporated more particularly, to a kind of high-salt wastewater low-temperature receiver
Method.
Background technology
In Chinese society economic development and urbanization process, it is sustainable that water scarcity is increasingly becoming restriction China
One of principal element of development strategy.In recent years, with the plant-scale continuous increase of China, industrial water consumption increases sharply.Meanwhile,
Produce wastewater flow rate also to increase rapidly, huge challenge is brought to current wastewater treatment and recovery and utilization technology.Industrial wastewater
As directly discharged, serious pollution will be produced to surrounding soil, water body environment.Waste water through process it is qualified it is up to standard after, if do not reclaimed
Utilize, then cause water resource waste, aggravate shortage of water resources.For high-salt wastewater, due to lacking technology, feasibility economically
With reliability, it is most of to take the outer discharge method of dilution.This method not only can not really reduce the total emission volumn of pollutant, and
The discharge of the waste of fresh water, particularly brine waste is caused, fresh water water resource mineralising and alkalization of soils (Lee's handle certainly will be caused
Edge, waits high-salt wastewaters to be formed and its treatment technology progress [J] chemical industry progress, and 2014,33 (2)：493-497).
Heat pump techniques are that the global energy for receiving much attention in recent years uses technology, and its core concept is a small amount of Gao Pin of consumption
Potential energy, porter is served as with heat energy, and the heat " taking out " of low-temperature heat source is arrived high-order thermal source.Flow the refrigerant in heat pump
It is to be formed by kind of refrigeration cycle.The refrigerant for being compressed is transported under the driving effect of electric power and other energy, refrigerant is steaming
Heat is absorbed in hair device, heat exchange is completed within the condenser, the flow of refrigerant in throttling expansion valve control system.Various types of
In the heat pump of type, the vapor compression heat pump pressure technology of driven by power is comparative maturity, and its standardization level is high, volume
Small, efficiency high, stable performance, maintenance cost is low, and leader more with the obvious advantage than other heat pumps and rapidly becoming market (opens
Research [J] the modern industries economy of sword heat pump techniques application principles and informationization, 2015,88 (4):9-20).
Spray technique is increasingly paid attention in the application study of field of seawater desalination in recent years, and it is a class to be developing progressively
Independent desalination technology.Spray evaporation desalination technology is the desalination method based on low-temperature phase transfer process, unit scale flexibly, set
Standby investment is moderate, it is convenient to which using Lowlevel thermal energy (such as solar energy, underground heat, factory's used heat), therefore application potential is very big.Spray
The principle of mist evaporation desalination is in vaporific penetrating vaporization chamber, while there is air circulation in vaporization chamber by seawater by shower nozzle；It is outstanding
Floating drop volume very little in the gas flow, diameter is typically within 100 μm, and specific surface area is very big, is easy to be carried out with surrounding air
Heat transfer, evaporation turns into vapor to the moisture in seawater rapidly, and thus seawater is concentrated；After evaporation process terminates, water steams
Gas takes vaporization chamber out of by air stream, fresh water is then condensed into again and is reclaimed.Seawater is dense in spray evaporation desalination process
Demagnification rate is very high, and it is (Cheng Huaigang, high from Congjie [J] modern chemical industries, 2008,28 (6) that salinity can even crystallize precipitation：19).
Method for treating water based on electromagnetic field effect is the new water technology for just growing up in recent years,
Its degradation process energy consumption is low, low cost, easy to operate, non-secondary pollution, is a technology for great development prospect.In high frequency traveling wave
Under magnetic fields, negative ions are made spiral circular motion in opposite direction by the effect of electromagnetic field Lorentz force in water, quite
In a direction identical circular electric current, a small circular electric current is acted on by magnetic field can be with for its dipole moment (abbreviation magnetic moment)
It is bright.The direction of magnetic moment can also deflect with the change generating period in magnetic field, while positive and negative charge center of gravity can be with the change in magnetic field week
Phase property is vibrated.Additionally, current-carrying coil is generally subject to rotating torque, translational force in non-homogeneous high-intensity magnetic field and causes the tension force of deformation
3 kinds of power effects, the effect of these power is all to try hard to make increase by the magnetic flux in roundlet current coil.Although there is ion heat fortune
Dynamic obstruction, but as external magnetic field is stronger, ion magnetic moment arranges more neat；With the movement in shape ripple magnetic field, current-carrying coil exists
Magnetic field is shifted under above-mentioned effect compared with strength.Because travelling-magnetic-field is moved in one direction, therefore negative ions helical ring can be with
The moving direction in magnetic field and moved to a direction, so that substantial amounts of ion can be brought together, play the work of removal of impurities
With (Wang Dongli waits electromagnetic water treatments Research progress [J] oil field equipments, 2007,36 (1)：9-11).
