Description
Technical field
The utility model relates to industrial cycle water technology and device for electrochemical water preparation, is specifically related to a kind of electronic box structure that is used for the stable device for electrochemical water preparation of circulating water quality.
Background technology
Industrial circulating cooling water is in constantly recycling, and water evaporates in cooling tower, and saltiness increases gradually, and the tendency that fouling is separated out on heat transfer interface of the lime carbonate in the water increases.The pH value of water coolant, temperature, nutrient all are fit to microbial reproduction, if do not controlled, system's foundry loam are increased, and deposit in interchanger.Fouling and foundry loam deposition cause the interchanger heat exchange efficiency to descend, and energy consumption increases, and can be forced to stop production and damage equipment when serious.
Traditional circulating water quality stabilising method are to add chemical agent, as Scale inhibitors, Biocidal algae-killing agent, dispersion agent etc., but have following drawback:
1, medicament is many is main with phosphorus, easily water body environment is produced eutrophication, regulation in national standard " Code for design of industrial recirculating cooling water treatment " GB50050 " should not made direct current water and uses through adding recirculated cooling water after Scale inhibitors, inhibiter and Biocidal algae-killing agent are handled ", could discharge after up to standard so must handle.
2, for making circulating water system steady running, frequent situation according to the monitoring lacing film, adjust the classification and the adding consistency of medicament; And medicament that adds and drug concentration are bigger to the influence of the heat-exchange equipment in the circulating water system.
3, from the long-time running angle analysis, though the first investment of chemical method is not high, annual medicament expense usefulness, labour cost, the electricity charge, maintenance cost etc. are higher always.
4, high concentration multiple easily causes equipment corrosion or fouling, and cycles of concentration can not infinitely improve.In order to limit cycles of concentration, will increase blowdown flow rate, waste water resource.
Device for electrochemical water preparation can be with the Ca in the water
2+, Mg
2+Ion takes out with solid form, reduces recirculated water hardness, reduces the new water yield and the blowdown flow rate that replenish, and the conserve water resource also has the function of sterilization algae removal simultaneously, has reduced adding of chemical agent.The subject matter that existing electro-chemical water treatment technology exists has:
One, is entangled in original basic theory
Electronic hydrotreater be American National aviation and NASA in late nineteen seventies invention in last century, early eighties is introduced China, the basic theory of proposition is the transition of electron opinion, the principle of work of proposition is " low voltage, little electric current ".This theory thinks that the character of water is determined by the motion of electronics in water molecules.In no external electrical field or extraneous masterpiece time spent, electronics is to be in the minimum track of energy level, and the water of this moment is the most stable.As external electrical field, promptly or during faint electric field action, peripheral electron just can transit to high level from low-lying level, and electronic cloud is changed, thereby activate water molecules, water molecules is reduced with potential difference between tube wall or disappear.Antiscaling effect is by there being the water molecules of excitation electron, i.e. the activated water molecule.
Produced the tandem product of electronic hydrotreater according to the principle of low voltage, little electric current.Handle least quantity 1～3m
3/ h, its power＜15W; Handle maximum amount of water 2000m
3/ h, its power is no more than 200W.Domestic all manufacturers all make product according to this principle and electrical parameter, simultaneously one of little advantage as electronic hydrotreater of energy consumption.
The disappearance of potential difference has influenced the water treatment effect of electronics water treatment as the argument of antiscale principle between fixing the principle of work of electronic hydrotreater at " weak electric field ", the water of transition of electron generation and tube wall.
Two, be entangled in install behind the pump theoretical
Install behind the pump opinion think the pump leaf of high speed rotating can reduce transition electronics, destroy the water dipole and surround Ca
2+Isoionic arrangement, the working lipe of influence " activated water " and the operating range of conduction.Therefore, the installation site will be chosen in the water pump back near protected equipment.The support that opinion does not obtain experiment is installed behind the pump, may be the result who guesses.Someone think be installed in pump after, can be beneficial near protected equipment to antiscale, scale removal.Opinion is installed behind the pump people's thinking has been bundled on the pipeline behind the pump and dare not crosses the water pump front, formed pipelining technology.Water treating devices such as all both at home and abroad electronics, high frequency, static all are mounted near on the water pipe of equipment.
Though pipelining technology has following advantage: can guarantee that 1. the pipeline water treater of all flowing through obtains handling; 2. can guarantee treater by flange bolt with piping system ground connection in good condition; 3. treater can be installed in the factory building the inside, and the envrionment conditions of a drying, health is arranged, and helps the operation of treater.
But also have more shortcoming:
1. electrolytic corrosion: electrolytic corrosion is a kind of electrochemical effect of electronic hydrotreater, is installed on the pipeline and all can produces electrolytic corrosion to pipeline and equipment, can't eliminate.Therefore, electronic hydrotreater can't improve the water treatment effect by improving electric current, and this may be the fatal shortcoming of electronic hydrotreater.
2. can not take out scale-forming ion from water, can only lean on single electrical effect to come the treating water intermediate ion, the water treatment effect appears in expectation.
3. installation must stop production: stopping under the condition of water cycle cutting pipeline, welding flange and connecting tube.
4. can't adjust recommended current: electric current is a steady state value, is difficult to guarantee the water treatment effect according to different quality adjustment, and managerial personnel are no bottom in the heart.
5. need factory building, floor space big, the workload of installation and maintenance is big.
