Self-induction formula disinfection spraying apparatus

Technical Field

The utility model relates to a be used for the sterile atomizer of environment, concretely relates to can be according to disinfection atomizer of on-the-spot microbial contamination situation adjustment disinfectant quantity and kind belongs to public health equipment technical field.

Background

Disinfectants are agents used to kill microorganisms on a transmission medium to achieve disinfection or sterilization. Compared with other disinfection means, the disinfectant has excellent disinfection effect on the surfaces of narrow environments and environmental objects in places with dense personnel, and different disinfectant types can be selected according to different disinfection scenes. Common disinfectants that can be used for air disinfection include 200mg/L chlorine dioxide, 0.2% peracetic acid, 3% hydrogen peroxide, 100mg/L hypochlorous acid, all of which are highly efficient broad spectrum disinfectants and are less harmful to other organisms.

However, disinfectants are not only a class of "protective agents," but also a "hazardous substance. For example, inhalation of hypochlorous acid and ozone can lead to the development and exacerbation of asthma. At present, except hospitals, scientific research institutions, breeding plants and the like are equipped with professional disinfectant users due to special disinfection requirements, the disinfectant using process under most scenes has the problems of over-disinfection, insufficient disinfection, delayed disinfection time and the like, and particularly comprises the following steps: 1) the usage amount and time of the disinfectant depend on manual judgment, and the disinfectant is difficult to adapt to the actual pollution condition of microorganisms, in most cases, the disinfectant is used when the microorganism pollution occurs for a period of time, and the phenomenon that the disinfectant still remains in the environment after the sterilization is finished or needs secondary disinfection due to insufficient use of the disinfectant often occurs; 2) a higher misjudgment on a lower microbial contamination condition can also result in a better disinfection effect when directly used, but a high-concentration disinfectant with stronger harm to ecology and human health causes an additional harmful effect; 3) the single use of a disinfectant for disinfection leads to the generation of drug resistance of microorganisms, reduces the subsequent disinfection effect and even generates drug-resistant bacteria.

In order to solve the above-mentioned first and second problems, some apparatuses attempt to judge the amount of disinfectant to be used by judging the activity of microorganisms, and are called "self-induction type sterilizing apparatuses". However, the current self-induction type disinfection equipment has poor practicability in a self-induction mode. Part self-inductance formula disinfecting equipment reflects the activity of harmful microorganism in the place through the particulate matter concentration in the place that awaits measuring, biological temperature, biological density side, but these indexes and the correlation between the real microorganism activity are and unstable unanimity, and the space representativeness is not strong moreover, can't reflect the holistic microbial contamination situation in place rapidly, just can't avoid excessive disinfection or the not enough problem of disinfection yet. Some researchers try to introduce mature microorganism online monitoring technologies or equipment for scientific research such as carbon nanowires and WIBS into the commercial or civil field, but no technology is available for connecting the online monitoring technologies or equipment with disinfection equipment in series, and the cost is too high even in the future. In addition, the current methods for judging and increasing the using amount of the disinfectant by the self-induction type disinfection equipment take the absolute level of the activity of microorganisms as an index, but the index is very difficult to determine because the risk level of different microorganism types is very different, and the requirement for the calibration of the self-induction equipment for determining the accurate absolute level of the activity of the microorganisms is very high, so that the realization is very difficult.

Volatile Organic Compounds (VOCs) emitted by microorganisms are an important source of indoor VOCs, and the detection of microbial marker VOCs is a convenient and rapid alternative method for detecting microorganisms. For example, indole can be used to indicate Escherichia coli, methylnicotinate can be used to indicate Mycobacterium tuberculosis, 2-nonanone can be used to indicate Pseudomonas aeruginosa, etc. Ethanol, n-butanol, isoamyl alcohol, formaldehyde, acetaldehyde, isobutyraldehyde, benzaldehyde, acetone, 3-hydroxy-2-butanone, 2-nonanone, acetic acid, propionic acid, 3-methyl-butyric acid, ethyl acetate, ethyl butyrate, amyl butyrate, indole, hydrogen sulfide and trimethylamine are common VOCs released by indoor microorganisms, and the combination of the above can well reflect the activity of the microorganisms.

Several techniques are described for sterilizing sprays for microbial contamination.

Chinese pending patent application CN202010638083.2 discloses a mobile ready-to-use ozone disinfection sprayer which can be applied to offices and public areas by preparing and spraying high concentration ozone water to kill microorganisms. The invention is typical 'non-self-induction' type microorganism disinfection equipment, the spraying amount and time of the disinfectant can only depend on human judgment, and the disinfectant is difficult to adapt to the actual pollution condition of microorganisms, and the disinfectant is used in most cases when the microorganism pollution occurs for a period of time. The actual effect of disinfection lacks effective evaluation, and the phenomenon that a large amount of ozone still remains in the environment after the disinfection is finished or secondary spraying is needed because of insufficient use of the disinfectant easily occurs. In addition, only using ozone as a disinfectant can easily cause the microorganisms to generate drug resistance, and the subsequent disinfection effect is reduced.

Chinese utility model CN207505674U discloses a sheep hurdle with automatic disinfection function, which is provided with a self-induction type disinfection spraying device. The utility model discloses a through set up the content that the microorganism detector detected the inside microorganism of sheep hurdle body at the fence middle part, trigger ozone generating device when exceeding standard and begin to produce ozone and disinfect. However, the specification does not describe which method of detecting microorganisms is used, and if the specification refers to a mature microorganism on-line monitoring apparatus for scientific research, the cost is too high. Moreover, the equipment only uses ozone as a disinfectant, which easily causes the generation of drug resistance of microorganisms, especially in the sheep pen where the microorganisms are dense. In addition, this utility model judges that the index of the pollution problem appears is the absolute level of microorganism activity ratio, but the definite very difficult of this index, even use very accurate instrument, because the risk level difference of different microorganism kind is very big, and the absolute level of confirming accurate microorganism activity ratio is very high to the requirement of self-induction equipment calibration moreover, and it is very difficult to realize.

Chinese on trialThe invention patent application CN202010257191.5 provides an automatic spray disinfection system in livestock and poultry houses, similar to the utility model CN207505674U above, which attempts to use fine Particulate Matter (PM)_2.5) As a trigger point for the self-sensing disinfection device. The method also has the problems of easy causing the microbial drug resistance of the place, high measurement difficulty and the like. Most critically, bioaerosols are indeed one of the important indicators of the level of microorganisms in the air, but PM is nevertheless present_2.5Is difficult to represent the activity of the microorganism, which may not even be PM_2.5Is the main source of (1). In addition, after sterilization is completed, PM even if microorganisms die_2.5Does not drop very quickly and triggers the spray device, resulting in an excessive use of disinfectant.

How to trigger degassing unit and change disinfection intensity through the design of self-induction formula, the simple method that uses and to represent the microorganism activity degree, and the disinfection quantity of disinfectant in the guarantee disinfection process is accurate, and the disinfection time does not lag, avoids the microorganism to produce drug resistance as far as possible, is the problem that present public health disinfection field needs to be solved.
