Product Description
Chemical Laboratory Fume Hood Lab Fumehood Exhaust Fume Cupboard
The fume hood should have the following functions
1. Release function: It should be equipped with a mechanism to absorb harmful gas generated inside the fume hood by absorbing the gas
outside the cabinet to dilute it and remove it outside. Isolation function: In front of the fume hood, there should be a non-sliding glass window to
separate the inside and outside of the fume hood. Heat resistance and acid and alkali corrosion resistance: Some of the fume hoods must be
equipped with electric furnaces, and some experiments produce a large amount of acid and alkali and other toxic and harmful gases, which are
extremely corrosive. The countertops, liners, side panels, and the selected water nozzles and air nozzles of the fume hood should have anti-
corrosion functions. Where strong acids such as sulfuric acid, nitric acid, etc. are used in the semiconductor industry or corrosive experiments, the
overall material of the fume hood must be acid-proof and must be made of stainless steel or PVC.
2. Non-reverse flow function: The airflow generated by the exhaust fan inside the fume hood should have the function of preventing harmful gas
from flowing into the room from the inside of the fume hood. In order to ensure the realization of this function, it is a method to connect a fume
hood and a ventilator with a single pipe. It cannot be connected by a single pipe. It is also limited to the same room on the same floor and can be
connected in parallel. The ventilator should be installed in the pipe as much as possible. At the end (or at the top of the layer).
3. Supplementary function: There should be a passage or alternative device for sucking in air from outside the fume hood when exhausting
harmful gases.
4. Wind speed control function: In order to prevent harmful gases from escaping in the fume hood, a certain suction speed is required. The factors
that determine the inhalation speed of the air in the fume hood are: the heat generated by the experiment content and the relationship with the
number of air changes. The main ones are the content of the experiment and the nature of the harmful substance. It is generally stipulated that
the general non-toxic pollutant is 0.25-0.38m/s, the toxic or dangerous hazardous substance is 0.4-0.5 m/s, the highly toxic or has a small amount
of radioactivity is 0.5-0.6m/s, and the gas is 0.5m/s, granular material is 1m/s. In order to ensure such a wind speed, the exhaust fan should have
the necessary static pressure, that is, the frictional resistance when the air passes through the ventilation duct. When determining the wind speed,
you must also pay attention to the noise problem. When the air flows through the pipe, the limit is 7-10m. Noise will be generated if the air is over
10m. Usually the laboratory (indoor background noise level) noise limit value is 70dBA. Reducing the wind speed also reduces the noise
. Considering the cost and construction of the pipeline, the power of the pipeline and the exhaust fan must be carefully selected
