Description
Affiliated technical field
The utility model relates to a kind of disinfection by chlorine dioxide machine in disinfection technology field.
Background technology
Dioxide peroxide is not only the sterilizing agent of a kind of efficient, wide spectrum, safety, but also be that multiple functions such as algae removal, anticorrosion, fresh-keeping, deodorizing, bleaching, decolouring are arranged, all using widely in the fields such as bleaching of Drinking Water sterilization, sterilizing air, health care, food sanitation, environmental health and Industrial Wastewater Treatment, sanitary sewage disposal, fabric and paper pulp.
As far back as 1811, just there is human sulfuric acid the Potcrate acidifying to be made " yellow gas ", up to 1881, just the someone identified the mixed gas that this gas is chlorine and dioxide peroxide.The thirties in last century, dioxide peroxide has been realized suitability for industrialized production, and it is in sulfuric acid medium, and the sodium chlorate generates dioxide peroxide with sulphur dioxide reduction:
2NaClO
3+SO
2+H
2SO
4＝2ClO
2+NaSO
4+H
2SO
4 (1)
This reduction method is easy to operate, but efficient is low, has successfully developed the novel method R1 method of preparation dioxide peroxide the seventies again, and has put into production.R1 method SO
2, NaClO is raw material, need not add H
2SO
4:
2NaClO
3+SO
2＝2ClO
2+Na
2SO
4 (2)
This method side reaction is more, ClO
2In mix up a large amount of SO
2Gas, application is restricted.After this foreign scholar has developed R series and SVP series ClO successively in more than ten years
2Technology of preparing, wherein R series has R1, R2, R3, R3H, R5, R6, R7, R8, R9, R10, R11, R12; SVP series has SVP, SVS-HP, SVP-MeOH, SVP-LITE, SVP-SCS, SVP-SVW.In a word, the mode of production of dioxide peroxide is concluded and can be divided into two big classes: one, (reduction method, oxidation style, oxidation style cost are higher for chemical method.); Two, electrolytic process (technology is prematurity still).Wherein traditional salt acid system (R5 method) and methyl alcohol method (R8 method) are the typical processs of reduction method.
The salt acid system is without reductive agent, and sodium chlorate and hydrochloric acid direct reaction generate dioxide peroxide:
NaClO
3+2HCl＝ClO
2+1/2Cl
2+H
2O+NaCl (3)
In this reaction biology 1/2 chlorine is arranged, chlorine easily produces organic halogen and mutagens such as THMs to drinking water disinfection and xanthohumic acid FA reaction, and this is a kind of carcinogenic substance, and is very harmful to human body.And purity is low, and transformation efficiency is low.
The methyl alcohol method is to make medium with sulfuric acid, and methyl alcohol is made reductive agent, and the reduction sodium chlorate generates dichloride chlorine:
30NaClO
3+20H
2SO
4+7CH
3OH＝30ClO
2+10Na

This reaction output capacity height is mixed with chlorine body in the chlorine dioxide.
At present, in view of the dioxide peroxide product that domestic and international dioxide peroxide device is produced, purity is lower mostly, or is mixed with chlorine or is mixed with sulfurous gas or is mixed with harmful side product such as carbonic acid gas, has limited the application of dioxide peroxide.
The utility model provides a kind of transformation efficiency＞98%, and purity＞95% does not contain harmful side products such as chlorine, and safe and reliable, production cost is low, disinfection by chlorine dioxide machine simple to operate.
Summary of the invention
Disinfection by chlorine dioxide machine principle of work is to adopt H

This reaction conversion ratio height, purity height; Do not produce chlorine, drinking water disinfection is not produced organic halogens such as THMs, do not produce mutagen.
The purpose of this utility model provides a kind of easy, safety, cost is low and multi-functional disinfection by chlorine dioxide machine.It has overcome that the security that present dioxide peroxide generation technique exists is low, purity is low, product P H is to drawbacks such as strongly-acids.
The technical scheme that its technical problem that solves the utility model adopts is: the A charging basket is connected with A material volume pump, the B charging basket is connected with B material volume pump, volume pump is connected with mixing tank, A, the B material is stirred by the volume pump injecting mixer, mixing tank is connected with the spiral tube reactor, mixed solution input spiral tube reactor, spiral tube reactor select materials is a metal titanium, spiral tube places water bath, the water bath select materials is macromolecule resin CPVC, electric heater places water bath, electric heater heats up water bath, temperature sensor places water bath, temperature sensor remains in 75 ℃ ± 2 ℃ the scope spiral tube reactor, when mixeding liquid temperature reaches 75 ℃ in the spiral tube reactor, react rapidly, generate chlorine dioxide, aeration pump is connected with reactor, reactor is connected with transfer line, aeration pump is blown into transfer line with chlorine dioxide, and transfer line is connected with separator, and separator is connected with absorption unit, reaction generates dioxide peroxide and enters absorption unit, separator is connected with knockout tower, and the solution of complete reaction does not pass through separator again, enters knockout tower, knockout tower is connected with aerator, by the aerator aeration, carry out secondary separation, the chlorine dioxide after the separation injects absorption unit through water sprayer, knockout tower is connected with knockout tower bed material case, the separated bed material case that enters of vitriol raffinate.
In operational process, controller is the work of watch-dog all the time.When power supply stops suddenly, change direct supply automatically, keep aerator non-stop run 30min; When in A, the B charging basket during a kind of insufficient raw material, close volume pump automatically, and send the warning buzzerphone, resume work automatically after supplying raw material; When the solid fault of volume pump quit work, aerator non-stop run 30min reduced to normal temperature until heater temperature.Sufficient raw, cost are 74% of salt acid systems, are 28% of oxidation style, and be easy and simple to handle, safe and reliable.
