Abstract
The invention relates to an air micro organism purifying effect evaluation system, mainly comprising three parts: a machine room, a personnel operation zone and an exposed zone. The system of the invention not only can research air micro organism aerosol and evaluate the effect of air micro organism purifying device, but also can be taken as a microbiological lab capable of effectively protecting the environment and operational personnel in the lab, thus realizing function division and providing an airtight work environment in relatively negative pressure.
Description
Technical field
The present invention relates to a kind ofly can carry out aerocolloidal research of air microbe and air microbe purifier Evaluation on effect; can effectively protect environment and laboratory operation personnel's Microbiological Lab again, be specifically related to a kind of air micro organism purifying effect evaluation system.
Background technology
Air is the important medium of microorganisms spreading, and a lot of human disease bacterium air-borne transmissions cause disease popularity.As being disease once by the serious harm human health of spittle air-borne transmission in the popular atypical pneumonia of China.Microorganism can be by aerosol transmission in air, and microbe species is many, and the survival ability in environment, virulence variation also show as various, and the aerial variation of microbial aerosol also is variation.Therefore, be necessary the strictly controlled environment factor, simulate the Microbiological Lab that an environment can control the variation of microbial aerosol is studied.
For air microbe in the control room pollutes, the propagation that wards off disease, a lot of units develop various air microbe purifiers, and some product is put on market.But various air microbe purifiers are widely different to micro organism purifying effect in the air, and China does not still have unified evaluation methodology at present, does not also have the aerobiology laboratory of suitable air microbe purifier effect assessment.Domestic experiment place of generally adopting be the aerosol cabinet that " disinfection technology standard " (2002 editions) are stipulated, this equipment is an airtight experiment and checkout gear, in actual use, has following problem: this installs that often volume is less (1), and 1m is only arranged
3Size is difficult to guarantee the obturation effect in the experimentation; (2) complicated sampling apparatus is put in inside, is difficult to guarantee that microbial aerosol is evenly distributed in inside; (3) can not be used for the evaluation of air microbe purifier; (4) structure and the disinfection way of inside are not made clearly regulation.
In the prior art, international application no PCT/IB2003/001250, JP2002-1045306, JP2002-326078, JP2003-102054 relate to the method and apparatus of estimating the microbial decontamination clean-up effect, but ubiquitous problem is 1, potential microorganism is leaked do not take safeguard procedures, or only take outside checkout gear, to add in addition appearance cover device and carry out shutoff simply, and this can only reduce leaking of microorganism, and can not fundamentally avoid.Yet, for some high-risk microorganisms, as strong morbific infectiousness pathogenic bacteria etc., even sometimes one by one the leakage of body also can cause very serious consequence, therefore, must fundamentally solve leakage problem.2, any facility that is used for self sterilization is not set in the device, therefore, the sterilization cleaning of installing self is very inconvenient, brings potential error source for actual the use; 3, stipulate each wall intersection in the device, is the right angle as can be seen from embodiment, cause gathering of dust, microorganism easily, and the right angle is unfavorable for agitator blender gas colloidal sol uniform distribution; 4, the microbe sampling pipe is longer, and has 90 ° of elbows, and the sampling loss is big.
