The fan is an indispensable supporting equipment for the bag filter. It is mainly used to transport air and provide the required power for the dust removal system to overcome the resistance loss caused by the air flowing in the system. If there is no supporting fan, it will cause dust removal. The air volume of the device is insufficient, and the dust removal efficiency decreases. It can be seen that the choice of bag filter fan is very important.
The selection and design of the bag filter fan needs to be calculated according to the air volume of the filter, system resistance, regional atmospheric pressure and dust temperature. Let's calculate the air volume first. The air volume is mainly the chimney discharge of the dust removal system. Different equipment has different discharge volumes, and the selection of the air volume should be calculated according to the size of the dust collection hood. The fan is driven by an electric motor to provide power for the air flow. Generally installed behind the bag filter, it can protect the fan, prevent the fan from being intruded by particles such as dust and impurities, and reduce the wear and erosion of the fan. After calculating the processing air volume, the next step is to calculate the system resistance, and then select the dust removal fan according to the air volume and resistance.
When choosing a bag filter fan, the following factors need to be considered:
Air volume requirements: Determine the air volume of the fan according to the amount of air to be processed, usually expressed in cubic meters per hour or cubic feet per minute.
Pressure requirements: Determine the head or wind pressure of the fan according to the air pressure to be treated, usually expressed in pascals or inches of water column.
Noise requirements: Determine the noise level of the fan according to the noise limit of the environment, usually expressed in decibels.
Energy Requirements: Determine the fan's power consumption, usually expressed in watts or horsepower, based on the volume and pressure of air to be processed.
Environmental conditions: Consider the temperature, humidity, corrosiveness and other factors of the application environment, and select the appropriate material and protection level.
Based on the above factors, you can contact the manufacturer or supplier to consult their technical engineer or sales representative, provide your specific requirements and application scenarios, and they will be able to choose the appropriate dust removal fan model and parameters for you.
