Fire exhaust fan should do the proper placement exhaust fan fire has now been applied to a lot of occasions, it is not the same application on different occasions, but in the major occasions, exhaust fan fire have played no small role, but we have to be the right place, the only way to better play its superior performance: professional fire exhaust fan accurate analysis of the efficiency value is known, fire exhaust fan is a high efficiency fan, it ratio of shaft power and effective power between the actual process gas or less. Currently, the total pressure efficiency exhaust fan fire in about 90%, while in the future development of fire exhaust fan, the efficiency value will be one of the objectives pursued by researchers further. Fire exhaust fan in the course of their work, although the pressure and speed of the impeller rotation for gas has improved, but a variety of small amount of gas varies, so the fan design and use of the process, the gas is usually not as the compressed fluid to deal with. Process gas exhaust fan fire were completed in the same radial plane, fire exhaust fan is based on the principle of potential energy is converted to kinetic energy, the use of high-speed rotation of the impeller the gas to accelerate and then decelerate, change the flow of exhaust fan fire structure, kinetic energy is converted into potential energy (pressure). In the single-stage fire exhaust fan fire exhaust fan in technology, from the axial gas into the impeller, the gas flows through the change to radial impeller, and then into the diffuser. In the diffuser, the gas flow direction changes cause deceleration that the deceleration effect the kinetic energy is converted into pressure energy. Pressure increased mainly in impeller, diffuser happens next in the process. In the multi-stage exhaust fan fire, and by the reflux stream allows the impeller to the next, resulting in a higher pressure. I am sure the fire exhaust fan efficiency values ??already know the exhaust fan fire, our application process in the future, we will continue to be improved to make efficiency value will be higher, its scope of application It will be more extensive. Fire exhaust fan suction device which specific classified it I am sure the exhaust fan fire is not strange, since it is now widely used in the major wind turbine industry, and its ultra-high performance has been overwhelming majority of users of universal recognition, but the main performance exhaust fan fire with its adsorption device has a great relationship, then its main suction device which classified it, we take a closer look at: 1, adsorption bee wheeled device fireproof fan Bee wheeled suction device is a new type of harmful gas purifying device, suitable for low concentration, the amount of wind conditions, with a relatively light quality, volume is relatively small, the operation is very simple and other advantages. 2, the fluidized bed of a fluidized bed adsorber the adsorbent in adsorber multilayer fluidized bed adsorber, the gas to be purified by means of a large flow rate, was suspended fluidized state. The main advantage of fluidized bed adsorber is contacted with an adsorbent gas exhaust fan fire better specifications, suitable for continuous emission control and a large volume of pollution. 3, fixed bed adsorption device mounted on a fixed-bed adsorption apparatus exhaust fan fire mostly fixed adsorption layer adsorption layer penetrate to replace the adsorbent. If the concentration of harmful gases is relatively low, but volatility is not, do not consider the adsorbent regeneration, while ensuring the safety of the adsorbent and adsorbate discarded along. Fire exhaust fan suction device specific classification is mainly these, I believe we have some understanding, and we must be reasonable use of it, the only way to get full use of its performance.
