Description
Technical field
The utility model relates to a kind of device, especially a kind of embrane method desalinating process strong brine is processed, and to improve the device of this water recovery utilization rate, belongs to the Treatment of Industrial Water technical field.
Background technology
In recent years, the embrane method desalting technology has obtained development at a high speed at home, with ultrafiltration, and nanofiltration, the forms such as reverse osmosis are widely used in industry-by-industry, and same, this embrane method desalting technology is also being brought into play more and more important effect in water treatment field.But the processing of the strong brine that produces for the embrane method desalinating process, the but good method of neither one so far.At present, the most frequently used method for treating strong brine can be divided into two large classes in the world, and a class is direct discharging, as enters ocean, surface water, Sewage treatment systems etc.; Another kind of is that strong brine is recycled, and as surface irrigation, salt manufacturing, extraction industrial chemicals etc., can effectively utilize resource, creates certain economic benefit.
The mode of the dense water of China's domestic processing embrane method desalinating process mainly contains following several now:
1, circumfluence method.Strong brine refluxes can improve the rate of recovery, increases the membrane surface flushing flow velocity, reduces dirty stifled.This kind method need to be controlled recurrence rate, and drawback is, if recurrence rate is too high, can make into the water salinity to raise, and easily fouling increases the burden of film, affects the life-span of film.
2, reuse is as water of productive use.Due to no suspended substance in strong brine, contain Scale inhibitors and pressure is arranged, can be used as backwashing water, water in dust removal, punching ash flushing cinder water, the water coolant of filtration unit, also can reclaim through sneaking into former water after simple the processing.But this method drawback is, if contain the pollutent that Environment Priority is controlled in strong brine, needs careful use, and use range is not high.
3, recycling.Can adopt water turbine supercharging blower, merit interchanger and pressure exchanger etc. to utilize the overbottom pressure production capacity; Desalimtor can be used for salt manufacturing with dense water, saves the salt pan, shortens and evaporates brine the cycle; Suitably blend after pre-treatment, can be used for culturing marine products, this method drawback is to be subjected to regional impact large, and cost of investment is high.
4, distillation and concentration.Membrane distillation (MD) technology is a new technology, namely utilizes the temperature difference dense water can be reclaimed as much as possible (rate of recovery 〉=95%) even crystallization under normal pressure, but economy, high-quality dewatering microporous film that present MD technology is used are are not yet researched and developed maturation.Domestic common employing is introduced evaporation tank with strong brine, processing and utilizing sun power and do not need other energy on the spot nearby, but this method drawback is also comparatively obvious, and this method is higher to the selectivity of region, and more arid area is more applicable.Leak if the evaporation tank of this method is constructed the unreasonable strong brine that very easily causes, penetrate in body of groundwater and cause groundwater pollution.
Therefore, in sum, although at present the processing of the domestic strong brine that the embrane method desalinating process is produced has certain understanding, but be limited to present state of the art, embrane method desalinating process strong brine is processed the defective that all has more or less, and as large in energy consumption, the ground field selectivity is high, broad spectrum is low, and difficulty of construction is large, high in cost of production.
Summary of the invention
