According to the Environmental Protection Agency, indoor air pollution is often two to five times higher than outside air pollution. Air pollution can be significantly higher in industrial buildings, especially manufacturing factories and chemical processing facilities. In addition, byproducts of the manufacturing process, including dust particles, oil mist aerosols, and condensed vapors, can build inside and outside of the equipment, causing problems with process quality, equipment maintenance, and worksite safety.
Air and other gases are purified by removing harmful particles by industrial filtration. Numerous industrial operations necessitate air filtration and separation systems to protect equipment and the working environment.
Protecting Equipment from Harmful Contamination Ingestion
During the production process, contaminants can be exceedingly detrimental to equipment. One of the essential functions of industrial filtering is to capture and eliminate these impurities and contain them for removal and disposal.
For instance, vacuum pumps are widely used to remove moisture from a product to make a powdered component in the pharmaceutical industry. Some moisture or powder particles may be discharged into the air stream leading to the vacuum pump during this procedure. This residue may eventually clog equipment and cause damage to rotating components. In this instance, both a liquid separator and a particulate filter would protect the vacuum pump from liquids and particles.
Depending on the chemical component, more intense production processes might release hazardous aerosols and vapors that can cause vacuum pump failure or possibly a combustion event (s). Therefore, the industrial air filtering system must eliminate these hazardous byproducts to maintain the equipment's functionality. In this situation, a vapor condensing trap would ensure that harmful vapors are adequately condensed and removed.
Eliminating Impurities to Purify Air and Gas Streams
Industrial filtration is essential in pneumatic conveying, additive manufacturing, and landfill gas collecting applications. Keeping the air and gas free of impurities during operations helps assure the purity of the process outputs.
Air and gas filtration must be exhaustive and quantifiable to ensure the removal of dangerous or undesired pollutants. The outputs of many industrial manufacturing processes must be clean and contaminant-free; even tiny fluctuations in contamination levels can render items worthless.
The presence of dust particles in the final product is a common problem encountered when making plastic parts. Using pneumatic conveying, a blower moves plastic pellets or powders from a storage bin to a piece of production equipment, such as an injection molding machine, using compressed air. The blower draws ambient air from the surrounding environment and then compresses it to push raw plastic ingredients through transfer tubes. Frequently, airborne dust particles in the ambient air intake can result in the rejection of entire batches. A pressure blower would be protected by an inlet air filter or a combination inlet air filter and silencer in this application.
