Raw foul smell, moisture and the toxic and harmful gas such as inflammable, explosive, perishable prevent in experiment to protect the safety of user
Toxic and harmful gas spread in experiment, it will usually laboratory is separated into the multiple regions including main chamber and concubine, it is main
Room be detained for a long time with personnel and operate it is some without chemical test that is poisonous and harmful, thering is gas with foreign flavor to generate, it is then special in concubine
It operates and places for be also easy to produce chemical test that is poisonous and harmful, having gas with foreign flavor and some be also easy to produce poisonous and harmful substance
Experiment drug, tool, therefore concubine need to be provided with the extractor fan of the toxic and harmful gas quickly extracted, in order to
Generate it is poisonous and harmful quickly draw it out (extraction amount need to reach 2000m3/h), and then avoid harm to the human body, existing skill
It need to be supplemented from main chamber in art from the gas that concubine extracts, can also remain that the pressure of concubine is lower than the pressure of main chamber in this way
Power, so that the toxic and harmful gas of concubine is avoided to flow in main chamber, however entire laboratory is closed space, is tested indoor
Air is then entirely the purification that purification air-conditioning (and using high-power, more air-conditionings are just able to satisfy gas supplement demand) provides
Air, a large amount of extract then need a large amount of gas supplement of air-conditioning, and whole system runs unusual power consumption, and energy waste is very tight

Further, gas supplementary device further includes inside concubine s3 for incuding concubine s3 internal gas pressure
Baroceptor, control the first blower 10 driving motor revolving speed controller, baroceptor connect with controller signals,
Controller controls the driving motor revolving speed of the first blower 10 according to the induction information of baroceptor.In this example, set in controller
The parameter value for the relative pressure set is -5pa, and the driving motor of the first blower 10 is electrodeless variable-speed motor, when baroceptor sense
When should arrive relative pressure in concubine s3 lower than -5pa, the driving motor that controller controls the first blower 10 accelerates to rotate so that the
One blower 10 accelerates make-up gas, when baroceptor senses that the relative pressure in concubine s3 is equal to -5pa, controller control
The driving motor constant revolution for making the first blower 10, when baroceptor senses that the relative pressure in concubine s3 is higher than -5pa
When, controller controls the driving motor underdrive of the first blower 10 so that 10 deceleration make-up gas of the first blower.Pass through sensing
Intelligence cooperation between device and controller when so that system starting, remains that concubine s3 is in the state of tiny structure, to avoid
Toxic and harmful gas in concubine s3 flows backward in main chamber s2, avoids security incident.In addition, by air cleaning system to
Be passed through clean gas in main chamber s2, and the relative pressure in main chamber s2 be maintained at 5pa, that is, remain in main chamber s2 in it is micro- just
Pressure condition can also be flow backwards even if there is of short duration micro-positive pressure in concubine s3 in this way to avoid toxic and harmful gas in concubine s3
To main chamber s2, so that the toxic and harmful gas further effectivelying prevent in concubine s3 flows backward in main chamber s2.
In this example, there are two concubine s3 settings, two concubine s3 are located at the two sides of main chamber s2.Convenient for carrying out simultaneously
A variety of experimental implementations for generating poisonous and harmful substance discharge, applicability are stronger.Supplement pipeline in this example includes the first main pipeline

Two sidewalls on), the second blower 20 be set to the second main pipeline 21 on, third subtube 22 and the 4th subtube 23 are by installation space
S1 extend downward and through ceiling board a1 respectively to two sides concubine s3 top.It supplements pipeline and extracts each pipeline in pipeline out
It is reasonably spaced apart mounting hole is interior.
Further, ceiling board a1 is that the full thread sunpender a2 vertically extended by more hangs and is located at building structure
(bottom of full thread sunpender a2, which is hung, sets fixed link a3, and fixed link a3 passes through pendant a4 and ceiling board in the middle part of the inner space of body 100
A1 connection, so realize ceiling board a1 hanging), the first main pipeline 11, the first subtube, the second subtube, the second main pipeline 21,
Third subtube 22, the 4th subtube 23, purge pipe 31, connecting pipe 34 etc. are lifted on installation by full thread sunpender a2
In the s1 of space.Full thread sunpender a2 not only lifts ceiling board a1, but also can also hang set each pipeline in above-below direction.So that
Structure design is more reasonable, and building is more convenient.
In conclusion chemical experiment chamber system of the invention is carried out by the way that gas supplementary device is arranged in concubine
When malicious harmful test operation generated, when gas collection apparatus extracts toxic and harmful gas out, which can be fast
Speed fills into gas in concubine from the external world, to avoid concubine extraction gas by leading indoor gas come the case where supplement；
To avoid air cleaning system (air-conditioning) from supplementing a large amount of gas into main chamber, air cleaning system highly energy-consuming is avoided,
Laboratory electric energy is substantially reduced using burden, high-power more air-conditioning equipments is also avoided while using, to alleviate air-conditioning
The expense of the setting of equipment is paid.
The present invention is described in detail above, its object is to allow the personage for being familiar with this field technology that can understand this
The content of invention is simultaneously implemented, and it is not intended to limit the scope of the present invention, all Spirit Essence institutes according to the present invention
