Description
Technical field:
It is hypochlorous composite disinfectant manufacturing technology field the utility model relates to main component, it is specifically a kind of
Main component is hypochlorous composite disinfectant process units.
Background technique:
Currently, three kinds are broadly divided into hypochlorous acid thimerosal as main component, and highly acid hypochloric acid water, faintly acid time chlorine
Sour water and subacidity hypochloric acid water.Highly acid hypochloric acid water, general call is acidic oxidized electric potential water at home, or acid
Electrolysis water, electrolyzed functional water, acidic oxidized electric potential water Ph value is usually 2~3, and effective chlorine density leads between 50~70mg/L
Electrolytically generated with cation membrane progress frequently with having, electrolytic pole board generallys use the platinum electrode with coating.
Hypochloric acid water production system, application number: 201410133057.9 applyings date: 2014-04-03 haves no right deemed withdrawal,
Hypochloric acid water is generated using electrolysis chlorine-containing disinfectant, then mix acid liquor adjusts pH value, after using motor to extract electrolysis
Liquid and acidic liquid are mixed.Only motor, valve arrangement on be described, do not illustrate the specific structure of mixing arrangement
Form and control method.
A kind of subacidity hypochloric acid water preparation method and device, application number: 201611042325.1 applyings date: 2016-
11-23 directlys adopt hypochlorite solutions and acid solution mixed form, and reaction unit uses two reactor tanks, and liquid is added and adopts
Flow container is mixed in the connection second level after connecting mixed flow container with ejector, after first order ejector, and first order ejector can be because of institute at this time
Having pressure to be all gathered in second flow mixing device two causes the air inlet of first order flow mixing device to be normal pressure, gas for gas feed
The problem of cannot mixing, spraying outward instead.
The preparation of acidulous hypochlorous acid generallys use undivided cell, electrolyte using NaCl, HCL mixed solution or
Person's HCL weak solution carries out, a kind of mixer of another method such as patent and its control algolithm application number:
201510866055.5 applyings date: 2015-12-01, it is carbon dioxide and sodium hypochlorite reaction at weak which, which uses raw material,
Acid hypochlorous acid, the general pH value of this hypochloric acid water are 5~6.5, and effective chlorine density can be even higher adjustable in 20~200mg/L,
No matter the hypochloric acid water that electrolytically generated hypochloric acid water or chemical reaction generate, all generate hypochlorous acid molecule, oxidation is also
Former current potential between 800~1000mv, test proves that, bactericidal effect has no too many differences, document 1001-0580
(2008) 11-1378-02 chemical synthesis electrolyzed oxidizing water toxicity assessment shows it to Oral toxicity and micronucleus test and stimulation
Property with electrolysis water indifference.
Highly acid hypochloric acid water or acidulous hypochlorous acid are generated using electrolysis form, there are 1, water quality to need to purify, no
Then electrolysis effectiveness can be influenced because of calcium and magnesium ion, cause the corrosion or deposition of motor pole plate, influence the service life of electrode pad,
At present in the often in the case where of falling pole, the common electrode pole plate service life is 4000h, and the hypochloric acid water chlorine taste being electrolysed out is heavier, is generated
Biggish generator is measured since high-power electrolysis unit power consumption is big, complex manufacturing technology, higher cost, is easy to happen explosion,
The unreasonable toxic chlorate etc. easy to form of cell construction is one of the difficult point in industry, in addition at present to environmental requirement compared with
Height, the discharges such as hydrogen and part the chlorine spilling of release, the alkaline water generated do not meet environmental requirement, are electrolysed the hypochlorous acid of form
Water application is restricted.
Pollution can be reduced using sodium hypochlorite and carbon dioxide mix mode, and raw material are unrestricted, time of generation
Chloric acid water chlorine taste is low, but pH value is minimum to be reduced to 5.3 or so since carbon dioxide is dissolved under normal pressure after water, hypochloric acid water
Oxidation-reduction potential is increased with the reduction of PH, and in disinfecting process, Disinfection Effect is also with the reduction of pH value and redox electricity
Position raising and become faster and better, the lower stage hypochlorous acid molecule content of effective chlorine number determine oxidation-reduction potential
Size and disinfecting power, after effective chlorine density reaches a certain level, the increase of available chlorine content be conducive to hypochloric acid water reduction
The influence of organic matter interference, in practical applications, to improving, Disinfection Effect is strong, and excessively high thimerosal concentration may cause
Residual.It would therefore be desirable to have control pH value, the available chlorine contents of effect.
In the current disinfecting process of sodium hypochlorite, the problem is that needing to hydrolyze sodium hypochlorite or connect with acidic materials
Touching can play biggish effect after generating hypochlorous acid, and liquor natrii hypochloritis is in alkalinity, and under alkaline environment, sodium hypochlorite holds
Easily and organic matter is at chloroform, trichloronitromethane etc..Under acidic environment, then the organic matter, but different rings are not easily formed
There are still generate in border.
Electrolysis form generates hypochloric acid water, has a small amount of ozone to generate, and has the hydrogen peroxide of trace to generate.Ozone, which is used as, to disappear
Toxic agent has preferable facilitation to Disinfection Effect, is obtained according to experiment, and ozone is able to suppress hypochlorous acid (hypochlorous acid) and generates chlorine
The harmful substances such as imitative, but simple ozone is easy to react with bromo-containing substance in water and generates bromoform, hydrogen bromide etc., and combine
Hypochlorous acid, ozone, hydrogen peroxide combined disinfection can have the generation for being easily reduced noxious products, enhance antivirus effect, and reduction individually makes
With ozone and hypochlorous concentration.And since the solution of ozone, hypochlorous acid and addition hydrogen peroxide is more unstable, it is therefore necessary to existing
It makes current.Electrolysis water since it is not adjustable its each material concentration and ratio, tests prove that, the concentration for adjusting each substance has
Conducive to the promotion of Disinfection Effect, be conducive to the generation for inhibiting harmful substance, when advantageously reducing the exclusive use of single sterile products
Concentration, ratio between different substances can be adjusted according to conclusion (of pressure testing) to realize different stages for various different occasions,
The Disinfection Effect of friction speed.Therefore compounded methods have bigger benefit relative to electrolytic hypochloric acid water, and have bigger
Flexibility.
The method mixed in hypochloric acid water or current chemical industry and chemical industry equipment using more two kinds and plurality of liquid
Convection current mixing, diffusion mixing and shearing three kinds of methods of mixing can be divided into, device has the reaction kettles of various structures, ejector and quiet
State mixer etc..

Kettle, then reaction kettle volume should could at least mix sufficiently more than tens to several hectolitres, and reaction kettle proof pressure then needs greatly wall
Thickness reaches 10mm or more, and volume is big, and sealing is bad, at high cost.If wall thickness is also required to 5mm or more using metal reaction kettle,
Due to corrosivity, particulate metal is needed to be made, cost and weight are high, if increasing agitating device in reaction kettle again, at
This and weight are more surprising.Under existence conditions, using reaction kettle, if be not stirred, liquid will appear different journeys
The lamination of degree, in particular for the liquid with pulsation input.Although can by the mixed structure with stirred autoclave
To realize stirring, mixed function, but the manufacture difficulty of reaction kettle is increased, while the hydraulic pressure born is limited, additional protective device

Product is heavy and cumbersome, higher cost, a reaction kettle market price make corrosion resistance reaction kettle cost more generally 10,000 or more
Height realizes that the high usual wall thickness of reaction kettle of compression resistance will reach 5mm or more, and entire reaction kettle weight will reach several hundred kilograms, show
It is not so optimal selection.
At this point, when user proposes rigors to the volume, cost, weight of equipment, while requiring in concentration switching,
Reach stable as early as possible, therefore it is required that mixing efficiency height in the mixing of high requirement liquid or gas-liquid mixing process, good corrosion resistance, resistance to
Pressure is high, while requiring mixed reactor small in size, and structure is simple, at low cost, and stability is good etc..
The mixing of liquid also may be implemented using ejector and static mixer, and whole process is mixing without mixing, is mixed
It is preferable to close effect, but the ejector of smaller size smaller and static mixer cannot cope with pulsation concentration liquids mixing, to cause defeated
The problems such as fluctuation of concentration is big out, reacts insufficient, and mixing efficiency is not high.According to large volume ejector or static mixer, no
It is disconnected when increasing static mixer to close to reactor volume, it is only capable of solving fluctuation of concentration to a certain extent for pulsation input asking
Topic, but cost is multiplied, and volume, weight increase therewith, also limit the small of compound hypochlorous acid thimerosal production equipment
Type, lightweight.
