Description
Technical field
The present invention relates to a kind of biology laboratory equipment more particularly to a kind of Biohazard Safety Equipments with heat exchange function.
Background technology
Biohazard Safety Equipment is that have infective experiment material for operation primary culture, bacterium strain and diagnostic sample etc.
It, can during so that it is avoided exposure to aforesaid operations for protecting operator, laboratory environment and experiment material when material
Can generate infectious aerosol and spatters and design.Biohazard Safety Equipment can be divided into level-one, two level and three-level three categories with
Meet different biological studies and epidemic prevention requires.
For example, level-one Biohazard Safety Equipment can protect staff and environment without protecting sample, air flow principle and laboratory
Draught cupboard is the same, the difference is that exhaust outlet is equipped with HEPA filters.Level-one Biohazard Safety Equipment Blower-free itself relies on outer
The wind turbine connected in air hose drives air-flow；For another example, two stage biological safety cabinet is the cabinet type being most widely used at present, also there is air-flow
Front window opening is flowed into, for preventing the aerosol that may be generated in microbiological manipulations from escaping from front window, with level-one bio-safety
Unlike cabinet, filtered inlet air flow can be captured before reaching working region by air-inlet grille, therefore trial target will not be by
To the pollution of outside air；For another example, three-grade biological safety cabinet is the safety cabinet of current highest class of safety protection in the world, cabinet
Completely airtight, all gas is not involved in cycle, and staff is operated by being connected to the gloves of cabinet, and trial target passes through double
The pass box disengaging safety cabinet of door is not contaminated to ensure, is suitable for the biologic test of high risk.
From the foregoing, it will be observed that Biohazard Safety Equipment is widely used in health care, disease control prevention, bio-pharmaceuticals, environmental monitoring etc. respectively
Operating personnel and Environmental security are protected in class biology laboratory field, prevent the pathogenic microorganism diffusion of operation from personnel being caused to injure
And environmental pollution.The safety of Biohazard Safety Equipment depends primarily on negative pressure in cabinet, and Biohazard Safety Equipment passes through constantly by gas in cabinet
It emits, then room air is absorbed by front window and is supplemented in come to form negative relative state；And Biohazard Safety Equipment is placed
Space largely all have higher requirements to humiture, cleanliness factor etc., a large amount of room airs are discharged, then mean the huge of the energy
Big waste.
Although in some mega projects, total-heat exchanger is increased in central exhaust system, Biohazard Safety Equipment
Quantity can change with the difference of project, and the exhaust air rate of single Biohazard Safety Equipment also can be because of security level, use state not
It is same and different, it can also cause exhaust air rate variation etc. in the same project because of the quantity for Biohazard Safety Equipment of devoting oneself to work, to increase
Add the design and control difficulty of central heat-exchange system, meanwhile, for the independent place for using Biohazard Safety Equipment, in air-conditioning system
Heat exchanger is configured in system, and system can be made to become very complicated.
Therefore, in view of the above, needing reasonably to improve the prior art.
Invention content
For disadvantages described above, the present invention provide it is a kind of can will discharge air in energy regenerating utilize and energy-saving and environment-friendly tool
The Biohazard Safety Equipment for having heat exchange function, to solve many deficiencies of the prior art.
To achieve the above object, the present invention uses following technical scheme：
A kind of Biohazard Safety Equipment with heat exchange function, include cabinet with powered air-purifying device and exhaust-air filter,

Biohazard Safety Equipment of the present invention with heat exchange function has the beneficial effect that：
(1) the air of cabinet is sent by circulating fan, and a part enters operation by powered air-purifying device as pure air
Room ensure that the air purity of operating room, another part air are discharged by exhaust-air filter, and operating room is made to form negative pressure shape
State tests indoor air and then enters operating room by biological safety cabinet door, to make harmful aerosol will not be from operating room
It overflows, protects the health of operating personnel；
(2) outdoor fresh air obtains the energy in air draft, then the three-level by elementary, middle and high filter by the filter core that exchanges heat
Filtering becomes high-quality air, and protection heat exchange filter core is not contaminated and makes air uniformly through heat exchange filter core, effectively increases and changes
The fresh air of the heat exchange efficiency of hot filter core, high-quality is either sent directly into laboratory or as the new of Laboratory Central Air-Condition System
Wind can effectively reduce the load of Laboratory Air-conditioning System, save energy expenditure, also can effectively extend important in central air conditioner system
The service life of component and consumptive material；
(3) can accomplish just to carry out each important component according to the characteristic requirements of equipment in every safety cabinet design and manufacture
Optimum performance matches, and improves the Operating ettectiveness of equipment, therefore, when separate unit is used without the concern for complicated recuperation of heat system
System, at more simultaneously in use, the connection of consideration fresh air pipeline and exhaust duct is only needed, to enormously simplify central air-conditioning
The design difficulty of ventilating system.
(4) it is equipped with complete air conditioning valve by heat exchange case, the various of Biohazard Safety Equipment can be conveniently adjusted
Operating parameter may be implemented to be digitized control to Biohazard Safety Equipment after each valve increases electric operator and inductor
And remote management.
