Description
Technical field
The utility model relates to laboratory environments to protect field, belong to a part of experimental laboratory air exhausting system, especially relate to
And a kind of auto purification laboratory hood.
Background technique
It is most importantly degassing function in the function of vent cabinet, in chemical laboratory, when experimental implementation, which generates, various to be had
Evil gas, foul smell, moisture and inflammable, explosive, corrosive substance prevent the dirt in experiment to protect the safety of user
It contaminates substance to spread to laboratory, vent cabinet is used near pollution sources.It is most importantly degassing function in the function of vent cabinet,
In chemical laboratory, when experimental implementation, generates various pernicious gases, foul smell, moisture and inflammable, explosive, corrosive substance,
In order to protect the safety of user, prevents the polluter in experiment from spreading to laboratory, ventilation is used near pollution sources
Cabinet, previous vent cabinet is less using number of units, only uses in particularly detrimental and dangerous gas and the experiment for generating big calorimetric.It is logical
Wind cabinet only undertakes the miscellaneous function of experimental bench.In view of improving experimental situation, the experiment carried out on experimental bench is gradually transferred to
In vent cabinet, this requires to have the function of being most suitable for equipment and use in vent cabinet.The laboratory especially created mostly is all
It is required that having air-conditioning, therefore will be by the plan for being included in air-conditioning system using number of units of vent cabinet in the concept phase of building.
Since vent cabinet occupies very important position in Biochemical Lab, from improvement laboratory environment, improve labour health condition,
It improves working efficiency etc. to consider, the use number of units of vent cabinet increases by leaps and bounds.Consequent is ventilation shaft, piping,
Wiring, air draft etc. all become the important topic of lab construction.
Maximum purpose using vent cabinet is that the pernicious gas generated in experiment is discharged, the health of Protection personnel,
That is to have the safety and superior operability of height, this requires vent cabinets should have following function：(1) function is discharged
Energy：Should have the pernicious gas generated inside vent cabinet the mode for absorbing gas outside cabinet, it is made to dilute heel row except outdoor
Mechanism；(2) function is not flow backwards：There should be the air-flow generated inside vent cabinet by exhaust blower by pernicious gas out of vent cabinet
Portion does not reversely flow into indoor function.For the realization for ensuring this function, a vent cabinet and the single pipeline of a ventilation blower
Connection is the best way, cannot be connected with single pipeline, is also only limited to can and connecting for same layer same room, ventilation blower to the greatest extent may be used
The end (or at layer top) of pipeline can be mounted on；(3) isolation features：Should have before vent cabinet with skid-resistant glass vision panel
It will be separated inside and outside vent cabinet；(4) supplementary functions：Should have when pernicious gas is discharged, air is sucked outside vent cabinet
Channel or replacement device；(5) controlled wind speed function：To prevent pernicious gas in vent cabinet from escaping, certain sucking speed is needed
Degree.Determine being known as the suction velocity of vent cabinet air inlet：The heat that experiment content generates and the relationship with rate of ventilation.Wherein
Important is the properties of experiment content and nuisance.Usually regulation, general nontoxic pollutant is 0.25-0.38m/s, toxic
Or dangerous nuisance is 0.4-0.5 m/s, severe toxicity or to have a small amount of radioactivity be 0.5-0.6m/s, vaporous object is
0.5m/s, shot-like particle 1m/s.In order to ensure such wind speed, exhaust blower should have necessary static pressure, i.e. air passes through ventilation
Frictional resistance when pipeline.It also must be noted that noise problem when determining wind speed, with 7-10m when flowing in pipeline by air
It is limited, noise will be generated more than 10m, (room background noise grade) the noise limits value in usual laboratory is 70dBA, increases pipeline
Wind speed can be reduced by cutting out area, noise also just be reduced, in view of the funds and construction problem of pipeline, it is necessary to careful selection pipeline and row
The power of blower；(6) heat-resisting and acid-alkali-corrosive-resisting function.
The current vent cabinet without air piping is to filter twice, and gas is exhausted directly to interior after filtering, and accordingly, there exist certain
Risk, if filter effect is bad, be exhausted directly to it is indoor influence whether whole indoor environment, can only in addition, filter twice
It is stronger to the specific aim of discharge gas, suitable for the exhaust gas of simple component, it is not suitable for the mix waste gas of more complex component；Again
Person, the glass vision panel of the observation of vent cabinet be typically all it is vertical, during testing crew is tested for observe sight
Tool has a certain impact, can be because the inclination of viewing angle generates certain deviation.
