In the construction of laboratories, the utilization rate of fume hoods is very high. When choosing the installation position of the fume hood, the type, material, shape, etc. of the fume hood must be considered.
When building a modern laboratory, sometimes it is necessary to configure a general-purpose laboratory in the laboratory hall. The laboratory bench, water basin fume hood, etc. can be moved at any time, and can be pushed when not in use. To the storage room. Movable fume hoods are generally made of wood, plastic or light metal, which is easy to move.
If a fume hood is needed in the laboratory to remove indoor air, it is more appropriate to use a side fume hood, because when the doors of the fume hood are all closed, it will not affect the replacement of indoor gas.
If an air conditioning system is installed in the laboratory or in a clean laboratory, the fume hood is an ideal place when supplementary air is used, which can save energy without affecting indoor air circulation.
It can continuously ventilate day and night (after testing, the indoor ventilation can reach 6 times/h), which is conducive to indoor ventilation; there is no noise and vibration; because there is no mechanical equipment, it is easier to maintain; structure Simple and inexpensive. The most important thing is not to consume electricity. However, its use will be restricted by certain conditions. Any experiment with high toxicity or no heat generation is not suitable for use, and some rooms are not suitable for use in summer.
The salient features of this fume hood are simple structure, convenient manufacturing, and suitable for occasions where heat is generated.
This type of fume hood is provided with exhaust slits on its top and back, which can achieve good results in various experimental environments. But the disadvantage is that the result is too complicated and the production process is more troublesome.
