Industrial extracting systems, also known as industrial ventilation systems, are used in various manufacturing and processing industries to remove airborne contaminants and improve indoor air quality. These systems employ various technologies to capture and remove contaminants such as dust, fumes, and vapors generated during manufacturing processes.
Here are some common components and techniques used in industrial extracting systems:
Capture hoods: Capture hoods are used to capture the contaminants at the source of emission. They are designed to effectively capture the contaminants in the vicinity of where they are generated, before they can disperse and cause air quality issues further downstream. Hoods can be either local exhaust hoods, which capture contaminants from a single source, or general ventilation hoods, which move large volumes of air from an entire workspace.
Ductwork: The captured contaminants are conveyed through ductwork to a central collection point or filtration system. Ductwork provides a transport path to move contaminated air from various local hoods and exhaust sources to a central air cleaning system.
Filters and air cleaners: After the contaminants have been transported from local hoods to a central point, they are typically passed through filters and air cleaners to capture the contaminants and restore the air quality to acceptable levels.
Fans: Fans provide the necessary pressure to move air and contaminants through the ductwork. Often, ventilation systems require high-pressure fans to overcome the resistance developed in the complex duct network.
Control systems: Control systems manage and regulate ventilation system components and operate based on the production process needs. Control systems use sensors and feedback to monitor and automate the speed of the fans, the number of hoods that need to run during a specific time and the number of filters and other required components.
Industrial extracting systems are widely used in industries like welding, food processing, chemical manufacturing, pharmaceuticals, among others, to protect workers from hazardous pollutants. These systems can also lower facility maintenance costs, enhance product quality, and increase overall productivity by keeping the air clean of contaminants.
In conclusion, industrial extracting systems are essential for maintaining clean air quality in industrial work settings. They employ a range of techniques, including capture hoods, ductwork, filters, fans, and control systems, to capture and remove pollutants and improve workspace air quality, ultimately ensuring the safety and wellbeing of workers and protecting the environment.
