Abstract
The objective of this research is to simulate the air velocity and pressure in plant air purifier with different filter materials. Three types of the filter material properties are as follows; type 1 porosity of 0.35 and pore size of 5 µm, type 2 porosity of 0.35 and pore size of 2.5 µm, and type 3 porosity of 0.7 and pore size of 2.5 µm. The different fan sizes are used as follows; 4" with volume flow rate of 37.5, 50 and 75 CFM, 6" with volume flow rate of 85, 113.33 and 170 CFM, and 8" with volume flow rate of 170.5, 227.33 and 341 CFM, respectively. The results of pressure difference and velocity obtained from the computer program simulation are found that the pressure difference and velocity increase with fan size. The fan size of 8" provides the maximum pressure difference of 96,885.293 Pa, the maximum fan speed of 6.228 m/s and the maximum outlet air speed of the material pot of 9.829 m/s. From the results of filter materials affected on the pressure drop and velocity, it is found that, at the same volume flow rate, type 2 provides the maximum pressure drop and fan speed followed by type 3 and type 1, respectively. The type 1 provides the maximum outlet air speed of the material pot followed by type 3 and type 2, respectively. Therefore, for the purpose of micro air filter of 2.5 micron, the proper filter material is type 3.
