Now, type suction device on the market, but also a wide variety of fire exhaust fan, consumers adsorption unit for numerous fire exhaust fan, and not be able to choose their own good, and today, small issue for We introduce a simple type adsorption device exhaust fan fire under it, so that consumers have a better understanding. 1, fire exhaust fan wheel suction device bee: Bee on fire exhaust fan wheel suction device is a new type of harmful gas purifying device, suitable for low concentration, the amount of wind conditions, with a relatively light mass, volume comparison small, the operation is very simple and other advantages. 2, fluidized bed adsorber fire exhaust fan: fluidized bed adsorber multilayer sorbent in a fluidized bed adsorber, the gas is purified by means of a large flow rate, it was a fluidized suspension state. The main advantage of fluidized bed adsorber is contacted with an adsorbent gas is better suited to manage large continuous emission and air pollution. 3, fixed bed adsorption unit exhaust fan fire: the fixed bed adsorption unit is installed on the exhaust fan fire mostly fixed adsorption layer adsorption layer penetrate to replace the adsorbent. If the relatively low concentration of harmful gases and volatile little time to consider the adsorbent regeneration, to ensure the safety of the adsorbent and adsorbate discarded together.
