You can determine if a desiccant air dryer is the perfect choice for your ideal compressed air application by learning how it works for yourself. Desiccant, in a summary, is a substance or material that has the capacity to absorb moisture from its environment. In order to prevent corrosion, mold, and other adverse effects associated with high humidity, it is frequently employed to decrease the moisture or humidity levels in the air, gases, or substances.
As for a desiccant air dryer or an adsorption dryer, it is a piece of industrial equipment that utilizes desiccant materials to remove water from the air that is directed through it. To ensure a continuous air-drying cycle, a typical desiccant dryer system employs a two-lower configuration.
An industrial desiccant air dryer that can regenerate its desiccant material by reversing the adsorptive process is referred to as a “regenerative” dryer. Typically, regenerative desiccant dryers are equipped with paired desiccant-packed structures that enable the simultaneous absorption of water and materials regeneration.
Desiccant air dryers are extensively utilized in industries that use compressed air. For instance, compressed air is essential for various operations within the oil and gas sector, including refining, transportation, and hydrocarbon recovery. The equipment employed in these processes is frequently susceptible to moisture-related damage.
The desiccant has failed and needs to be replaced and updated after long-term operation when the operating parameters of the drying system remain unchanged and the air flows normally but the dry air cannot attain the dew point requirement.
The pressure of the regenerated desiccant cylinder should be at least 0.05Mpa when it discharges exhaust gas. The muffler should be removed to clear the particles if the pressure exceeds this value.
In general, the exhaust pipe and muffler should be connected to the outdoor. However, the inlet volume flow must be connected to the outdoor if it is less than 10m³, and the pipe must be lower than the regeneration outlet height. Ensure that the gas flow resistance is low and replace the cartridge or muffler if necessary.
As we conclude, it is important to remember that desiccant air dryers are composed of two pressure vessels that are both filled with desiccant and operated through a switch-over. The moisture is completely removed by the desiccant as the damp compressed air passes through a vessel at a low temperature and high pressure, resulting in the compressed air being dry. Before making an investment in a desiccant air dryer, it is crucial to conduct additional research.
