Description
Technical field
The utility model relates to a kind of brine treatment system, belongs to water-treatment technology field.
Background technology
In recent years, China shortage of water resources problem is very serious, utilize salt solution (like seawater or trade effluent) thus carrying out desalination obtains fresh water, become a kind of trend.What industriallization brine desalination method was commonly used is divided into two types, hot method (MSF, low temperature multiple-effect distillation), embrane method (r-o-).Hot method is to utilize heat energy to make the phase transformation of salt water generates, and moisture evaporation is come out, and obtains fresh water through condensation.Hot method desalination need use steam as thermal source, dispose steam-generating installation (normally adopting large-scale fire coal, combustion gas or oil-firing boiler), and investment is big, and cost is high, and energy consumption is high.Embrane method is to utilize the salinity in the separatory membrane salt solution to hold back or remove, thereby obtains fresh water.The regular job of embrane method and safeguard complicatedly also need be carried out routine cleaning and replacing because film pollutes, and also need carry out pre-treatment, the working life of pretreated quality decision film to the seawater of the film of flowing through.
At present, what on above-mentioned hot method desalination basis, grow up is to utilize solar energy equipment to replace traditional chemical ability device, by following several kinds:
The one, with sun power direct heating salt solution.Like the disclosed solar energy sea water desalination apparatus of publication number CN101591042A Chinese patent; This device is with solar energy collector direct heating seawater; And, utilize heat pump to recycle vapor condensation latent heat again through vacuum pump acquisition negative pressure reduction evaporation of seawater temperature, accomplish sea water desaltination; But this device is with solar energy collector direct heating seawater; At most can only be heated to 100 degree (actual not reaching), the Absorption by Sea Water heat is not high yet, and also how high not meeting is certainly for the vapor condensation latent heat that under negative pressure, evaporates subsequently; And only depend on the not high seawater of negative pressure evaporation heat; Vaporization efficiency can be not high, and it is very low therefore to desalinate water rate, is difficult to suitability for industrialized production.The disclosed solar energy sea water desalination apparatus of notification number CN201678475U Chinese patent and for example; The difference of this device and above-mentioned solar energy sea water desalination apparatus is; Remove heat exchanger for heat pump the direct-fired seawater feeding of solar energy collector interchanger is evaporated the seawater of heating; As stated, because the heat of solar heating seawater is limited, it is very low therefore to desalinate water rate.Other are like the disclosed a kind of solar desalting device of publication No. CN101708872A Chinese patent, and the defective that exists with above-mentioned two kinds of Patent equipments is roughly the same given an example no longer one by one.
The 2nd, sun power indirect heating salt solution.Like the disclosed seawater desalination device employing solar energy and vapor compressing distillation of publication No. CN101723476A Chinese patent; This device is compared difference with above-mentioned publication number CN101591042A Chinese patent: cancelled heat pump; Through interchanger sun power is passed to seawater, with the steam of blower fan compression evaporation of seawater; This device feeds vaporization voluntarily in the negative pressure evaporation chamber with low temperature seawater of solar heating, utilizes vapor condensation latent heat to come the seawater the heating evaporation chamber in again, thus have still that vaporization efficiency is low, the fresh water water rate is low, can't industrialized disadvantage.The disclosed sea water desaltination low-temperature multi-effect of notification number CN2934211Y Chinese patent device and for example; This device wants to utilize sun power generation steam to evaporate seawater; But obviously directly produce the efficient very low (steam production is little) of steam, the needs of evaporation of seawater hard to carry on sun power.The disclosed solar-energy sea water desalting equipment of publication number CN1417132A Chinese patent for another example, this equipment produces steam with interchanger with the working medium of solar heating, again with steam through multiple-effect distillation device evaporation seawater to obtain fresh water; The steam consumption quantity that needs during this equipment distillation seawater is big, needs the solar heater of very extensive investment to satisfy, so vaporization efficiency still lower (being that the fresh water water rate is low), also is difficult to suitability for industrialized production.
More than illustrational each patent prior art also all exist a common defects to be: because sun power can not continue to provide energy, therefore only use solar energy collector, can't guarantee sea water by distillation or desalting equipment non-stop run at all.
In addition, the concentrated salt solution that above-mentioned prior art produced generally all is directly to emit (as being discharged in the sea), not only environment is worked the mischief (as causing the local ecology in ocean to change), and the salt in the concentrated salt solution is not fully used.
