Manufacture of environmental system for sampling solid chemical pollutants from air
Abstract
The purpose of this study is to manufacture an environmental system for collecting solid pollutants in the air and take it as a sampling method in order to conduct the necessary analyses later to determine the concentrations of the target pollutants. The sampling system is designed according to the Anderson model, and the system holders are made of stainless steel 304. This system includes four types of filters with different porosities (0.7µm, 1.3µm, 1.6µm, 8µm), and these filters are placed on the brackets of the system in order with the largest porosity at the top. The previous system is connected to an air cell, then the concentration of pollutants is calculated (after analyzied them using the appropriate techniques) based on volume of air withdrawn.The ability of this practical system to draw air is determined by (4.24 m3/h).
