Description
Technical field
The present invention relates to a kind of disinfectant and application thereof, especially a kind of solid-state chloride dioxide sterilizer and application thereof.
Background technology
Action of microorganisms such as chlorine dioxide has fast, efficient, wide spectrum kill bacteria, virus, though be a kind of of chlorine-containing disinfectant, but be different from chlorine-containing disinfectants such as bleaching powder, sodium dichloro cyanurate, in the aqueous solution, do not produce hypochlorous acid (root), not producing with organic molecule generation chlorination in disinfecting process has three to cause the material of effect, but reaches the purpose of killing microorganisms by the oxidation Decomposition microprotein.Chlorine dioxide by high praise be the 4th generation disinfectant, the World Health Organization classifies it as A1 level security high effect disinfectants, is widely used in that food, health care, beasts, birds and aquatic products are cultured and industry such as daily use chemicals.China begins the research of the aspects such as synthetic and application of disinfection agent of chlorine dioxide in the early 1990s in last century, research and development technology stable chlorine dioxide disinfectant disinfectant simple, that be convenient to transport is a research focus in disinfectant field always, has occurred a plurality of relevant patents in recent years.
Patent " the chlorine dioxide disinfectant generator " (number of patent application 98238593.5 that Zhu Mingyong applies in August, 1998, patent announcement number: CN2343152), mainly comprise sodium chlorate solution's material-storing box, the hydrochloric acid solution material-storing box and in establish reactor, chlorine dioxide mist gas storage chamber, the air gas storage chamber, the main body of heating water tank and water sprayer, be provided with the reaction of high order pipe in the reactor, under the water sprayer normal operation, sodium chlorate solution and hydrochloric acid solution flow in the reactor through the reaction of high order pipe, deliver in the pending water through the negative pressure that the outlet by chlorine dioxide mist gas storage chamber of the chlorine dioxide mist of fully reaction back generation is produced by water sprayer.The patent that Li Tianlei applies in March, 2000 " a kind of disinfection agent of chlorine dioxide and preparation using method " (number of patent application 00105012.5, patent announcement number: CN1315135), by the stable ClO 2 solution that alkali absorption obtains, chlorine dioxide valid density is 10-1000mg/l.Patent " a kind of preparation method of solid-state stabilizing chlorine dioxide disinfectant the agent " (number of patent application 200310114633.7 of Lie group in December, 2003 application, patent announcement number: CN1631769), by parts by weight account for chlorite, 1%～90% anhydrous calcium chloride and the anhydrous chlorides of rase sodium mixture of 0.1%-65%, the activator that 5%～75% tartaric acid, boric acid and hydrosulphate are combined into is formed; Prepare finished product by following operation: earlier that each raw material is dry respectively; In blending equipment, drop into anhydrous calcium chloride earlier, drop into solid-state chlorite again, add the mixture that anhydrous sodium sulfate blend or elder generation drop into anhydrous calcium chloride and anhydrous sodium sulfate again, add solid-state chlorite blend again; Add boric acid, tartaric acid, hydrosulphate blend more successively; The material that blend is finished packs promptly makes product.Patent " preparation method of monobasic tablet the disinfection agent of chlorine dioxide " (number of patent application 03137084.5 that Zhang Tian etc. apply in June, 2003, patent announcement number: CN1565192), with monobasic pulvis disinfection agent of chlorine dioxide is primary raw material, add a certain proportion of stabilizing agent, forming agent, desiccant and releasing agent, under the condition of suitable technology and ambient humidity, mix, the back of granulating makes solid sterilizing tablets on tablet machine.
Take a broad view of the patent of above-mentioned application, chlorine dioxide disinfectant generator belongs to a kind of gas generating unit, and the equipment seal degree is had quite high requirement.Owing to used severe corrosive reagent such as hydrochloric acid, equipment material requires high, invest bigger, simultaneously the user also must purchase sodium chlorate, consumable materials such as hydrochloric acid.During use, operate loaded down with trivial detailsly, be difficult to obtain the disinfectant solution of accurate concentration; Disinfection agent of chlorine dioxide (aqua) chlorine dioxide content is low, the term of validity is short, stores, transports dangerous; Monobasic tablet disinfection agent of chlorine dioxide technology comprises oven dry, mixing, moulding, and production equipment, environment, the packing of product are required height, and production, transporting procedures existence fire hidden danger.
