Description
Technical field
The utility model relates to a kind of intelligence control system, relates in particular to a kind of intelligence control system of full film water treatment facility.
Background technology
The be known as water technology of 21 century of membrane technology is to develop the rapidest, most widely used technology over nearly 40 years, and water treatment field is membrane technology most important applications field.
The membrane technology that is used at present water treatment in the commercial production mainly contains following several types: ultrafiltration (Ultrafiltration, UF), counter-infiltration (Reverse Osmosis, RO), electric desalination (Electrodialysis, EDI) etc.
Ultrafiltration is a simple physics sieve aperture detachment process, and the UF film has the hole of definite shape and size, and aqueous solvent and little solute particle see through film and arrive low-pressure side under pressure, and macroparticle component tunicle stops.The aperture of UF film is between nanometer and micron, and wherein detachment process does not have chemical reaction, phase transformation or dilution.In order to take into account separation accuracy and transmitance, general UF film is about 0.01 μ m.Former water can be held back all particles greater than 0.01 μ m by microporous barrier, as colloid (colloid silicon), pollen, algae, parasite, bacterium, virus, pathogen and organic macromolecule etc. under certain pressure drives.By the water outlet of UF, water stabilization, particularly the clearance of colloid silicon is highly stable, is subjected to raw water quality, operation condition effect very little.
Counter-infiltration is a kind of by means of the function of selecting to see through (semi-transparent mistake) property film, is the membrane separation technique of expulsive force with the pressure differential.When added pressure in the system during greater than solution osmotic pressure, hydrone constantly sees through film, flow into pipe core through producing water flow passage, flow out in the water side then, most inorganic salts and dissolved organic matter, bacterium, virus etc. during the composite membrane assembly can remove continuously and anhydrate, it is trapped in the influent side of film, flows out in dense water water side then, thereby reach the isolation of purified purpose.
The electricity desalination is called electrodialysis again, is the technology of carrying out water treatment by anion/cation exchange membrane, ion exchange resin, direct supply.Wherein anion-exchange membrane only allows negative ion to see through, and does not allow kation to pass through; And cation-exchange membrane only allows cation permeation, does not allow negative ion to pass through.Ion exchange resin fills to be clipped in and forms single processing unit between the yin, yang amberplex, and constitutes freshwater room.Separate with net between unit and the unit, form dense hydroecium.Direct supply yin, yang electrode at group two ends, unit forms electric field.Come the water current freshwater room of flowing through, the yin, yang ion in the water is eliminated by the yin, yang amberplex under electric field action, enters dense hydroecium.The ion exchange resin of filling has improved the speed that ion is eliminated widely between amberplex.Simultaneously, hydrone produces hydrogen ion and hydroxide ion under electric field action, and these ion pair ion exchange resin carry out cyclic regeneration, so that ion exchange resin keeps optimum condition.
Above three kinds of membrane technologies are combined the equipment that carries out water treatment, and we are referred to as full film water treatment facility.Comparing traditional ion-exchange water technology compares, full film water handle have the effluent quality height, produce continuously, easy to use, without soda acid, free from environmental pollution, advantages such as floor area is little, economical operation, be a kind of water technology of environment-friendly high-efficiency, therefore be applied in the water treatment of industries such as generating plant more and more widely.

In sum, though the control system of existing full film water treatment facility has adopted automatic control technology, but each solution is disperseed, find to integrate the complete intelligence control system of formation one cover, so the controlling level of present full film water treatment facility is not high, the running efficiency of device has much room for improvement.
