[0017] The electric pressure boost fan, also called desulfurization fan, is a device for producing airflow pressure boost by rotating impeller driven by motor. Its core components include motor, impeller, shell, etc. The electric pressure boost fan has the operating characteristics of low pressure head, large flow and low speed, and is an indispensable equipment in many industrial fields.

[0018] The working principle of electric booster fan is mainly based on the air flow boosting effect generated by rotating impeller. The specific process is as follows: motor drive: the motor drives the power output to the impeller through the transmission device, driving the impeller to rotate. The speed and power of the motor can be adjusted according to the needs. Impeller rotation: the impeller driven by the motor starts to rotate and generates air flow. The impeller is usually connected by a number of curved blades, and the shape and angle of the blades can affect the flow rate and direction of the air flow. Air flow boosting: the rotating impeller forms an air vortex. Due to the centrifugal force, the air is thrown to the periphery of the impeller, forming a high pressure area. At the same time, a low pressure area is formed inside the impeller. This pressure difference drives the air from the low pressure area through the blades into the high pressure area, thus achieving air flow boosting. Air flow discharge: the boosted air flow is discharged through the outlet of the fan and can be used for various industrial processes.

[0019] Electric booster fan has a wide range of applications in many industrial fields, flue gas desulfurization: in the flue gas desulfurization system, electric booster fan is used to overcome the resistance of FGD (flue gas desulfurization) device, to introduce the original flue gas into the desulfurization system, and to stabilize the boiler induced draft fan outlet pressure. Air compression: electric booster fan can be used to provide sufficient air for the engine in vehicles such as cars, trains, motorcycles, etc. In addition, it can also be used in laboratory gas compression, paint spraying and other chemical processes. Ventilation: in the construction, mining, chemical industry and other industries, electric booster fan is often used for ventilation. For example, in underground mines, it can provide fresh air for miners to ensure their safety. Air purification system, exhaust system, etc. also need booster fan for ventilation. Gas delivery: electric booster fan can be used for gas compression and delivery in urban gas pipeline, as well as gas compression in gas turbine.

[0020] The safety performance of the electric booster fan is the key factor to ensure its stable operation and prevent accidents. Mechanical seal: The electric booster fan usually adopts mechanical seal, which can achieve zero leakage and effectively prevent the leakage of special gas. Leakage not only causes resource waste, but also may pose a safety hazard to the surrounding environment. Therefore, mechanical seal is necessary, especially when handling special gases such as biogas and natural gas, which can better demonstrate its importance. Explosion-proof motor: The motor equipped with the fan adopts explosion-proof design, which can safely operate in a potentially explosive environment and avoid safety accidents. Overload protection: The electric booster fan has overload protection function, which can automatically cut off the power or reduce the power when the motor load is too large or abnormal conditions occur, preventing the motor from being damaged by overload and prolonging the service life of the unit. Speed regulation function: The fan has a speed regulation function, which can adjust the speed according to the actual demand to adapt to different working conditions. This not only improves the working efficiency of the fan, but also reduces energy consumption and noise to some extent. Stable operation: The electric booster fan is designed reasonably and operates stably and reliably. Its internal components are precisely machined and strictly tested to ensure long-term stable operation of the fan. Fault warning: The fan is equipped with a fault warning system that can monitor the operating status of the fan in real time. Once a fault or abnormal condition occurs, the system will immediately issue a warning signal to remind the operator to handle it in time to avoid the accident from expanding. Safe operation: The operation of the electric booster fan is simple and easy to understand, but the operator still needs to be trained and familiar with the operation procedures of the fan. During operation, safety operation procedures should be strictly followed to ensure that the fan operates in a safe state. Maintenance: Regular maintenance of the electric booster fan is an important measure to ensure its safety performance. Maintenance includes checking whether the fan components are intact, whether the fastening bolts are loose, whether the lubrication system is good, etc. Through maintenance, potential safety hazards can be found and eliminated in time. In different application scenarios, the fan may face different safety challenges and requirements. For example, in the flue gas desulfurization system, the fan needs to withstand high temperature, high humidity, corrosive gas and other harsh environments; in the air compression field, the fan needs to ensure that the compressed air is pure and pollution-free. Therefore, when selecting and using the electric booster fan, it needs to be customized and configured according to the specific application scenario and requirements.
