Description

A kind of digestion procedure of space hydrogen peroxide
Technical field
The present invention relates to a kind of rapid-digestion method of space environment disinfectant, gaseous state and dry fog peroxidating are based especially on After hydrogen sterilization in rapid-digestion air residual hydrogen dioxide method.
Background technology
Hydrogen peroxide is a kind of disinfectant efficiently, environmentally friendly.Environment is carried out using the hydrogen peroxide of vaporization or spray pattern Fumigation, space especially closed to one carries out high level disinfection processing, it has also become one kind is by more and more widely used life Thing decontamination measure.Generally with vaporized hydrogen peroxide (VHP), hydrogen peroxide steam (HPV) and hydrogen peroxide dry fog (HP~FOG) shape Formula, by the field extensive use such as pharmaceuticals industry, bio-safety and hospital infection control, the sterilization of such as high-level clean room, part Low temperature sterilizing and the terminal disinfection in the place such as ICU, ward online of pharmaceutical equipment, Biohazard Safety Equipment.It is this based on gaseous state or dry The hydrogen peroxide of mist has stronger diffusivity and osmosis, therefore also has stronger fungicidal effectiveness.After treatment, disappeared The hydrogen peroxide of higher concentration can be remained in poison ring border in longer time, health hazard can be produced to personnel, also can be to one A little production activities and product quality have a negative impact, so as to influence to be sterilized the use of environment;On the other hand, when for biology When the environment for learning experiment uses disinfectant with hydrogen peroxide, cytotoxicity, microorganism can be produced because of the presence of residual peroxide thing Growth inhibition etc. influences the unfavorable factor of result of the test.Therefore, the quick hydrogen peroxide removed in environment is needed after sterilization, to drop The adverse effect of low residual peroxide thing.
In existing removal air in the mode of residual hydrogen peroxide disinfectant, what is be widely used is carried out using air Ventilation displacement or natural degradation method.Both modes, which exist, clears up that time-consuming, inefficiency and the problem of be difficult to cleared, this Have a strong impact on the follow-up application for using, also therefore limiting this kind of disinfectant with hydrogen peroxide technology in processed region.
Also some similar researchs are directed to solving this problem, such as Chinese patent CN201310159540.X discloses one Plant hydrogen peroxide steam and decompose filtering material, be that filling is golden using divalence is based between layer glass fiber air filtering material Belong to ionic compound, such as manganese dioxide particulate filter is decomposed as catalyst, handled in the form of circulating filtration, Root is it was found that partially long, the problem of energy consumption is big and less efficient that similarly there is digestion time.
The content of the invention
The present invention is that deficiency present in solution prior art is cleared up in hydrogen peroxide disappears there is provided a kind of residual peroxide Solution thoroughly digestion procedure.
The present invention solve existing issue technical scheme method be:A kind of digestion procedure of space hydrogen peroxide, by biology Clear up enzyme preparation and produce aerosol in the way of spraying, the aerosol of atomization be suspended in particulate form disperse needed for clear up sky Between or sealing space in, the gaseous state or dry fog state hydrogen peroxide in closed environment are cleared up in Brownian movement mode.
As a further improvement, described every cubic metre of space spraying usage amount of biologically digesting enzyme preparation is 1~5ml.
As a further improvement, the aerosol particle particle diameter of described atomization is less than 10 μm.
As a further improvement, described aerosol is sterile aerosol;Described spraying is sterile spraying.
As a further improvement, described biologically digesting enzyme preparation includes 100mg~200mg peroxidating per 100ml components Methanol that hydrogen enzyme dry powder, volume ratio are 1%~10%, the phosphate buffer that surplus is pH6.0~8.0, described biology disappear Enzyme preparation copper ion concentration is solved for 1mmol/L~10mmol/L, activity of catalase is 2000U/ in biologically digesting enzyme preparation Ml~3000U/ml.
As a further improvement, described methanol volume ratio is 2%;Described copper ion concentration is 2mmol/L;Described Catalase dry powder is 200mg, and described phosphate buffer is pH 7.0.Peroxidating in described biologically digesting enzyme preparation Hydrogen enzyme activity is 3000U/ml.
As a further improvement, the packing material of biologically digesting enzyme preparation can be positioned in space to be cleared up in advance.
As a further improvement, described condensation aerosol is divulged information while clearing up space hydrogen peroxide.
Compared with prior art, its advantage is to give space to be cleared up or sealing by digestion instrument to the present invention The biologically digesting enzyme preparation of sprinkling atomization in space, the biologically digesting enzyme preparation of atomization can reduce what is remained in closed environment rapidly Concentration of hydrogen peroxide, no nuisance generation, recovery environment utilization ratio, harm of the reduction to personnel health and environment, saving electricity, Gas, reduces energy consumption.The inventive method is practical simple, clears up hydrogen peroxide effective.Apparatus of the present invention are simple in construction, are easy to quickly connect Connect.
