De-Gassing Your Components Using Pneumatic and Mechanical Separation Systems
The benefits of dedusting a facility’s existing air quality are numerous and long lasting. If your company works with or is considering purchasing a business, it is crucial to learn how it can be beneficial for the environment. In this piece, we will outline the process and provide examples of how it can improve air quality.
What do you mean by Dedusting?
Dedusting is the mechanical cleaning of fine particles, usually using some type of mechanical separation method. Mechanical separation can involve the removal of airborne dust by hand, but it also includes the physical removal of airborne fine particles. Many of today’s separation systems are powered by electric motors, which work in conjunction with powerful vacuum pumps. The result is a high-quality dust and fine particles removal that produce low amounts of noise and are highly effective.
A large percentage of industrial applications use a combination of mechanical separation and dedusting. Because mechanical separation uses the principle of forcing air into a material, the particles removed can contain very small dust particles as well as larger, airborne debris. For instance, mixing a few liters of paint with 100 grams of sand and blowing it into an air chamber can create large quantities of airborne dust and particles. In fact, it may be difficult to see the difference between the amount of sand and paint in the air and the amount of fine particles produced by the airbrush, making it difficult to determine whether or not the amount of fine dust contained in the mixture is less than the amount of regrind dust created by the grinding process.
One way companies can ensure that the air is free of dust and contaminants is through the use of a pre-registration cleaning system. Companies may purchase air brushes and fine-particle extraction units that are specially pre-registered with pneumatic separation machines. These machines are designed to extract large particles from the air, regardless of whether or not they are present in the ambient air. The particles removed by these machines are then taken to a demineralization plant where they are processed and purified.
Some companies also use a secondary process called electrostatic precipitation to remove hard-to-remove materials such as rust. There are a number of electrostatic precipitation systems on the market today and the primary advantage is that they are extremely affordable. Secondary, or post-registration, solutions are available that use iontophoresis to remove small particles from the air. These post-registration solutions also allow for larger particles and dust to be removed while the cleaning process is in progress. However, because of the increased cost of post-registration solutions, it may make more sense to simply hire a quality electrostatic precipitation service to perform the necessary steps of the mechanical dedusting system and then to have the secondary process take over once the main process is complete.
