Fan selection calculation
Thread Content
Our factory is planning to purchase a fan for pumping HCL gas. The manufacturer requires two parameters: air volume and air pressure. How can these two parameters be calculated? Thank you!
Air volume refers to the maximum volume of air that your equipment needs to exhaust, and this value must be converted into standard cubic feet. Air pressure, on the other hand, is the maximum pressure drop that will occur in your piping system once the fan is turned on; it needs to be calculated based on the pipe diameter, flow rate, and number of bends.
Just refer to the chemical process design manual
Calculate the indoor area and the HCL emission level; determine the number of air changes per hour required to maintain a certain concentration in the space, and then use this figure to calculate the rotational speed and air volume
It’s too simple. Calculate the output volume of your HCL; determine whether it will be discharged directly, transported through pipes, or used in some other way. If it’s discharged directly, then an adequate airflow is necessary. Will creating a negative pressure affect the rate of the chemical reaction?
