Abstract
The invention relates to application of an energy-saving water-saving ion exchanger in bitter desalting. The technique overcomes the defects of high investment, high energy consumption and waste of abundant water, and is an energy-saving water-saving bitter desalting technique. The application of the energy-saving water-saving ion exchanger in bitter desalting comprises the following techniques: 1) narrow electrode chamber technique: in the prior art, both influent water and electrode water of the ion exchanger flow in from the lateral side of the electrode chamber of which the width is 70-100mm, but in the narrow electrode chamber technique, water flows in through the end of the narrow electrode chamber of which the width is 15-25mm; 2) frequent electrode exchange technique: the power source of the ion exchanger adopts a silicon controlled rectifier dual rectification circuit, so the electrode exchange frequency can be adjusted freely; 3) thick water circulation technique: the thick water is partially circulated, so that the discharge of the thick water can reach 5%; and 4) non-metal corrosion-resistant electrode technique: the synthetic non-metal pressed film electrodes are adopted. The application technique of the energy-saving water-saving ion exchanger in bitter desalting can save the energy by 20-30%, saves abundant precious water resources, and lowers the operating cost.
Description
Technical field
The present invention relates to the utilisation technology in brackish water desalination, particularly relate to the utilisation technology of a kind of energy-saving and water-saving ion-exchanger in brackish water desalination.
Background technology
The utilisation technology that is applied at present in brackish water desalination mainly contains: resin ion exchange method, reverse osmosis method, Nanofiltering membrane, method of evaporation etc., but all there is certain shortcoming in various degree in the method for desalting brackish water of using at present, and is as large in facility investment, running cost is high, the power consumption is high, the waste water yield is large.Therefore, limited application in brackish water desalination.
Summary of the invention
The technical problem to be solved in the present invention is the shortcoming that how to overcome present brackish water desalination, and the application of a kind of energy-saving and water-saving ion-exchanger in brackish water desalination is provided.
In order to solve the shortcoming of present brackish water desalination, the utilisation technology of a kind of energy-saving and water-saving ion-exchanger of the present invention in brackish water desalination comprises following technology:
1. narrow utmost point chamber technology: the water inlet of ion-exchanger and utmost point water all pass through utmost point chamber from lateral intake, and utmost point chamber width is 70mm-100mm, and narrow utmost point chamber technology adopts end to water inlet, and utmost point chamber width is 15mm-25mm;
2. frequently pole-reversing technology: the ion-exchanger power acquisition is with the two rectifying circuits of silicon controlled rectifier, and the frequency of falling the utmost point is arbitrarily adjustable;
3. dense water cycle technology: adopt dense water section circulation, concentrated water discharge can accomplish 5%;
4. non-metal anti-corrosion electrode technology: adopt the synthetic non-metallic squeeze membrane electrode.
Embodiment
Following embodiment is for the more detailed the present invention of explanation, is confined to this but should not be construed as the present invention.
Embodiment 1:
1. narrow utmost point chamber technology; Ion-exchanger all passes through utmost point chamber from lateral intake, and utmost point chamber width is 70mm-100mm, and narrow utmost point chamber technology adopts end to water inlet, and utmost point chamber width is 15mm-25mm;
2. frequently pole-reversing technology; The ion-exchanger power acquisition two rectifying circuits of silicon controlled rectifier, the frequency of falling the utmost point is arbitrarily adjustable;
3. dense water cycle technology; Adopt dense water section circulation, concentrated water discharge can accomplish 5%;
4. non-metal anti-corrosion electrode technology: adopt the synthetic non-metallic squeeze membrane electrode.
The invention has the beneficial effects as follows:
1. owing to having adopted narrow utmost point chamber technology, reduce resistance, improved the electric current utilising efficiency, therefore can save energy 20%-30%;
2. because of electric current positive and negative electrode frequent changes (the utmost point), avoid ion-exchange membrane fouling and utmost point water to form, extended the work-ing life of ion-exchange membrane and pole plate;
3. adopt dense water cycle technology, therefore water conservancy, has saved the water resources of a large amount of preciousnesses with bringing up to 95%.
4. owing to having adopted the non-metal anti-corrosion electrode technology, be coated with than best titanium at present ruthenium electrode cost 5-6 doubly, be that titanium is coated with more than 2 times of ruthenium electrode work-ing life, therefore significantly reduced the electrode replacement frequency, reduced running cost.
Above design is only for explanation the present invention's, and be not to be limitation of the present invention, the those of ordinary skill in relevant technologies field, without departing from the spirit and scope of the present invention, other variation of having done and the technical scheme that all are equal to also should belong to category of the present invention.
