Abstract
The utility model relates to a pure water preparing device which is composed of a pretreatment part, a reverse osmosis membrane treatment part and an electrodialytic part, wherein an electrodialyzer is arranged between the pretreatment part and the reverse osmosis membrane treatment part. A reverse osmosis membrane treatment concentrated water outlet pipeline is connected with a pretreatment output pipeline, the pretreatment output pipeline is connected with a water inlet of the electrodialyzer, and a water outlet of the electrodialyzer is connected with a reverse osmosis membrane high pressure pump. The water inlet of the electrodialyzer is provided with a booster pump and a front valve set, and the water outlet is provided with a back valve set. A desalination device adopts the electrodialyzer with high water utilization rate, cations and anions in the water can be moved to the concentrated water of the cations and the anions through each ion selectivity osmosis membrane by direct current electric field force, and the ion concentration of most of salt in the water can be decreased. The decreasing degree of the ion concentration can be adjusted in a comparatively large amplitude, and the ion concentration can be decreased to 20 percent of the ion concentration of running water. The water can be supplied to the reverse osmosis membrane to be changed into pure water via the high pressure pump, the service life of the high pressure pump is extended, the operating life of the reverse osmosis membrane is extended, the workload of the pretreatment part is eased, and the water utilization rate can reach 75 percent.
Description
(1) technical field:
The utility model relates to the design and fabrication technology of producing the equipment that pure water uses.
(2) background technology:
Existing device for making purified water partly is made of preprocessing part and reverse osmosis membrane processing, because the intrinsic property of reverse osmosis membrane, determined the pure water producing water ratio only to be about 25% of the tap water that enters device for making, had 75% water to be thrown away, promptly condensed water is thrown away.Condensed water is very clean after pre-treatment, has not only wasted water resources, also wastes the resource of preprocessing process cost.
(3) summary of the invention:
The utility model solves the problem that pure water is produced existence emphatically, and its production rate is improved greatly, and the energy is saved in water saving.
The technical solution of the utility model is: partly be made of preprocessing part, reverse osmosis membrane processing part and electrodialysis, between preprocessing part and reverse osmosis membrane processing part, electrodialyzer is set, the dense water out pipeline of reverse osmosis membrane processing connects the pre-treatment delivery conduit, the pre-treatment delivery conduit connects the water-in of electrodialyzer, and the electrodialyzer water outlet connects the reverse osmosis membrane high-pressure pump.Water-in at electrodialyzer is provided with topping-up pump and early gate group, and the water outlet place is provided with the late gate group.
The beneficial effects of the utility model are: demineralization plant has adopted the electrodialyzer of high water use efficiency, rely on the direct current field force that the ion selectivity that the positive and negative ion in the water sees through is separately moved in its condensed water through film, salt ionic concn in most of water is descended, ionic concn reduces degree can regulate by a relatively large margin, is reduced to 20% of tap water.This water produces pure water through high-pressure pump for reverse osmosis membrane.The working pressure of high-pressure pump reduces, and in economize on electricity, the life-span of pump prolongs.Reliability improves, and the compaction effect of reverse osmosis membrane is little, and the film working life prolongs.The working load of preprocessing part alleviates, the water yield of pretreatment portion divisional processing is originally that reverse osmosis membrane produces 4 times of amount of purified water, present 1.25～1.55 times of only needing processing pure water output, 75% water use efficiency, make one ton of pure water and need about 1.33 tons in tap water, when pure water output was identical, the preprocessing part investment can be saved half like this, and economic benefit obviously improves.By the water rate of commercial tap water, the water rate of saving in a year can be offset the electrodialyzer installation cost, uses well, but steady operation 5 years.
(4) description of drawings:
Figure is the utility model structural representation.
(5) embodiment:
Device for making purified water as shown in the figure, by preprocessing part, reverse osmosis membrane processing part and electrodialysis partly constitute, between preprocessing part 1 and reverse osmosis membrane 7 treating parts, topping-up pump 2 and electrodialyzer 4 are set, the dense water out pipeline 8 of reverse osmosis membrane processing connects the pre-treatment delivery conduit to topping-up pump, topping-up pump output connects the water-in early gate group 3 of electrodialyzer, and the electrodialyzer water outlet connects reverse osmosis membrane high-pressure pump 6 through late gate group 5.Forward and backward valving is that four valve bridge-types connect.Being fouling on the film that prevents the dense water cavity of electrodialyzer at work, often changing the polarity of electrode, correspondingly change the position of light dense water cavity simultaneously, replaces by valving in dense water cavity fresh water chamber.This device can be used on large-scale water treatment machine and the automatic water vendor.Adopt the common machine processing technology just can produce.
