Description
Technical field
The present invention relates to disinfecting technical field, particularly relate to a kind of for little space chlorine dioxide gas sterilizing unit and measuring method, be applied to the sterilization of the surrounding air such as freezer, experimental box.
Background technology
Chlorine dioxide is a kind of disinfection sanitizer of internationally recognized efficient, nontoxic, quick, wide spectrum, and it has the sterilization effect of 100% to antibacterial, fungus, virus, spore.Existing such device installs Shortcomings part the gasification of chlorine dioxide and device, it is not thorough to there is chlorine dioxide extraction and isolation in the first, residual liquid concentration is high, it two is that the scene of being everlasting arranges chlorine dioxide generator, complicated operation, unsafe factor are strengthened, usual employing hydrochloric acid activation French, containing a large amount of chlorine in chlorine dioxide.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides little space chlorine dioxide gas sterilizing unit.Chlorine dioxide is applied to when freezer environmental gas is sterilized because chlorine dioxide liquid may cause damage to storage thing and storehouse body equipment etc., directly ClO 2 solution can not be sprayed, sterilization can not be crossed, must be that chlorine dioxide available gas is added, concentration accurately controls, so just require chlorine dioxide to be extracted from ClO 2 solution.
For achieving the above object, the invention discloses following technology contents:
The technical solution adopted in the present invention is:
A kind of for little space chlorine dioxide gas sterilizing unit, it is characterized in that: this device is made up of four partial functions, be respectively chlorine dioxide content in ClO 2 solution stores and transport portion, the cyclic aeration part of ClO 2 solution, centrifugal cyclone and centrifugal blower form air section, air and detect and control section; Wherein ClO 2 solution stores in the container 1, by dosing pump 2, ClO 2 solution is delivered to the liquid storage Lower Hold of centrifugal cyclone 6 bottom; ClO 2 solution circulating pump 3 is from centrifugal cyclone 6 Lower Hold inhalation solution, spray into from centrifugal cyclone 6 air inlet, ClO 2 solution is mixed in the gas of high speed rotating with water smoke, Chlorine Dioxide Molecules removes from solution with gas procedure, and hydrone is thrown toward eddy flow wall and flows back to centrifugal cyclone 6 Lower Hold; The concentration signal that in air, chlorine dioxide content detects and controller 8 collects according to chlorine dioxide concentration detecting sensor 7 in air sends control instruction to ClO 2 solution circulating pump 3 dosing pump 2 and centrifugal blower 5.Realize online dynamically concentration to control.Chlorine-dioxide residual-liquid after repeatedly aeration cycle then has overflow pipe 9 constantly to overflow.
ClO 2 solution of the present invention is not containing the pure chlorine dioxide aqueous solution (produced by other patented technology and obtain) of chlorine.Described dosing pump may also be peristaltic pump.
Pure chlorine dioxide aqueous solution of the present invention by shower nozzle with the mist-like wind entrance spraying into centrifugal cyclone, make pure chlorine dioxide aqueous solution strongly contact mixing with air, then mixed airflow high-speed rotary person in cyclone turn move downwardly to taper after turn back upwards from the discharge pipe of center discharged in the air.In mixed airflow high speed rotary motion, the proportion of liquid is large compared with gas, get rid of under centrifugal action to outer wall, liquid rotates downward flow back fluid storehouse along inwall subsequently, and the chlorine dioxide overflowed from ClO 2 solution is then added to space with rotational flow air.
The present invention makes pure chlorine dioxide aqueous solution constantly with the mist-like phase-splitting mixing circulation with high speed rotating by circulating pump, and repeatedly carry out aeration separation, chlorine dioxide extraction rate is accelerated, and extraction ratio is improved.In air, chlorine dioxide content detects and controls, and detects chlorine dioxide content in air, send control instruction to circulating pump, centrifugal blower and dosing pump by chlorine dioxide concentration detecting sensor chlorine dioxide sensor in air.
The present invention further discloses and adopt little space chlorine dioxide gas sterilizing unit to carry out the method measured, it is characterized in that being undertaken by following step:
1. ClO 2 solution is stored in a reservoir;
2. common two tunnels that can accept chlorine dioxide sensor signal are selected to export Programmable Logic Controller;
3. start chlorine dioxide controller, during the initial concentration value of the concentration that chlorine dioxide concentration sensor acquisition arrives in by air lower than setting, controller two way control switch sends operation instruction to circulating pump, dosing pump, centrifugal blower respectively; When the concentration that chlorine dioxide sensor detects is higher than the upper concentration value set, controller two-way switch sends halt instruction to circulating pump, dosing pump, centrifugal blower simultaneously;
4. a hole is opened in the position that centrifugal cyclone containing liquid chamber middle and upper part is concordant with taper hydrops mouth height, and hose connection as overflow pipe with PE, destroys gas-liquid separation effect to prevent hydrops too high.
5. in liquid storage Lower Hold, install float liquid level switch, be serially connected in the circuit of circulating pump, when the situation that generation liquid level is too low, forbid that circulating pump operates.
The present invention further discloses the application of method in preparation rapidly and efficiently separation chlorine dioxide adopting little space chlorine dioxide gas sterilizing unit to carry out measuring.The results show: the present invention utilizes ClO 2 solution constantly to carry out circulation in centrifugal cyclone and achieves repeatedly aeration, and utilize centrifugal action to achieve being separated of water and chlorine dioxide in ClO 2 solution.Chlorine dioxide detects and controls can be easy to realize data storing record and realize real-time communication with computer.Achieve little space constant concentration and maintain sterilization or timing sterilization, achieve Automatic Control.
The tetrameric operation principle of little space chlorine dioxide gas sterilizing unit disclosed by the invention is as follows:
(1) pure chlorine dioxide aqueous solution is stored in the container (1) of PVC material, 4 ~ 20mA that corrosion-resistant dosing pump (2) provides according to controller (8) or 0 ~ 10V speed-regulating signal carry out the running of corresponding speed, pure chlorine dioxide aqueous solution are added to the liquid storage Lower Hold of centrifugal cyclone (6) bottom.
