Description
Technical field
This utility model relates to a kind of biology laboratory equipment, particularly relates to a kind of life with heat exchange function
Thing safety cabinet.
Background technology
Biohazard Safety Equipment is to have infective for operation primary culture, bacterium strain and diagnostic specimen etc.
During experiment material, it is used for protecting operator, laboratory environment and experiment material so that it is avoid exposing
Issuable infectious aerosol and spatters during aforesaid operations and design.Biohazard Safety Equipment can
It is divided into one-level, two grades and three grades of three major types to meet different biological studies and epidemic prevention requirement.
Such as, one-level Biohazard Safety Equipment can protect staff and environment not to protect sample, air flow principle and
Laboratory fume hood is the same, and difference is that air vent is provided with HEPA filter.One-level bio-safety
The Blower-free of cabinet own, relies on the blower fan band moving air flow in external ventilation duct；And for example, two stage biological safety cabinet is
The cabinet type being most widely used at present, also has air-flow to flow into front window opening, is used for preventing when microbiological manipulations
The aerosol that may generate is escaped from front window, unlike one-level Biohazard Safety Equipment, and the air inlet of filtered
Stream can be captured by air-inlet grille before arriving working region, and therefore trial target will not be polluted by outside air；
For another example, three-grade biological safety cabinet is the safety cabinet of the highest class of safety protection at present, cabinet gas completely

The most contaminated to guarantee by two-door pass box turnover safety cabinet, it is adaptable to high risk biologic test.
From the foregoing, it will be observed that Biohazard Safety Equipment is widely used in health care, disease control prevention, bio-pharmaceuticals, environment
The different kind organism laboratory fields such as monitoring, protection operator and Environmental security, prevent the micro-life of cause of disease of operation
Thing diffusion causes personnel to injure and environmental pollution.The safety of Biohazard Safety Equipment depends primarily on negative pressure in cabinet,
Biohazard Safety Equipment is by constantly emitting gas in cabinet, then is supplemented into by front window absorption room air,
Thus form negative relative state；And the space major part that Biohazard Safety Equipment is placed is all to humiture, cleanliness factor
Etc. having higher requirements, a large amount of room airs are discharged, then mean the huge waste of the energy.
Although in some mega projects, central authorities' exhaust system adding total-heat exchanger, but biology is pacified
The quantity of full cabinet can change along with the difference of project, and the exhaust air rate of single Biohazard Safety Equipment also can be because of safe level
Not, use the difference of state and different, also can be because of the quantity of Biohazard Safety Equipment of devoting oneself to work in same project
And cause exhaust air rate variation etc., thus add the design of central authorities' heat-exchange system and control difficulty, meanwhile,
For the independent place using Biohazard Safety Equipment, configure heat exchanger within air-conditioning systems, system can be made again to become
Obtain the most complicated.
Therefore, for the above, need prior art is reasonably improved.
