The Best Ways to clean the air Compressor
Moisture is all over the surrounding and we cannot avoid it. Moisture levels in the air keep on fluctuating depending on the changes in temperature. Winter and summer seasons can change the amounts of moisture in our environments. We should be keen in observing the weather changes. An air compressor works well when it is devoid of water and moisture. The Best Ways to clean the air Compressor
However for the compressor machines to accumulate some amounts of water and moisture are normal. These are various ways in which an air compressor can be cleaned. Common practices to remove moisture from compressed air include:
Draining the tank
Using a water trap and filter regulator
Using a refrigerated air dryer
Using a desiccant air dryer
Using a deliquescent air dryer
Through piping system air drying
With the storage tank cooling method
Through absorption drying
What causes the air compressor to have some water and moisture?
The natural moisture that is prevalent during the process of compression and the type of quality of air being used by the compressor are the sole causes of the moisture present in the tank. The filtration system of the airbrush compressor that is tasked to separate pure air from other impurities may be overwhelmed by the level of moisture. This will automatically prompt one to use other methods to empty the water from the compressor tanks.
Factors that influence the level of moisture in the compressor tanks.
- Air conditioning
- Running water
- Leaking roofs or windows
- Poor ventilation
The Danger of Having Too Much Moisture in Your Compressed Air
Destruction of your air compressor: Excess water that remains stagnant for long leads to the rusting of the linings of the air compressor.
Staining of the compressor-A lot of moisture may stain some parts of the air compressor such as the bearings that make it difficult to function normally.
Degrades the quality: When the codes of the compressor are tainted then it is difficult to attain the set standards of quality.
Poor output: After the interior linings of the compressor tank are affected then the outcome will not be appealing.
How to Remove Water from Compressed Air.
Mostly some air that is compressed requires to be cleaned or dried of the natural moisture. There are numerous ways of removing some moisture from the air compressor which is easy or advanced in terms of their workability. Simple methods are those that involve drain valves while those advanced use a procedural stage drying system. Moisture or any water droplets may adversely affect the compressor machine.
While many other operations can put up with low moisture in their functioning and not necessarily require an air drying machine but with the air compressor, any amount of water or moisture is not appropriate. Therefore the practice of releasing some water is necessary.
Air compressors serve many purposes so there is no specific form of air that can be used in the air compressor. It requires so many systems to cool the compressor to boost its functionality.
Draining the Tank
This is the first stage that one must do to drain moisture from the lines of the compressor often. The drain that is located below the air compressor is responsible for releasing of oil and water that gathers at the bottom of the tank. This practice should be done concessionary to avoid some rusting of the interior part of the tank due to the accumulation of moisture and water.
Water Filter Regulator
This regulator works using a simple technique of using the incoming air to remove the moisture from the composer tank. The air that is allowed to the tank is allowed to settle on one side before moving along the bowls with the water that is collected below the tank. As the water drains out the air will escape out through a filter that collects other impurities.
This water filter and the regulator is purely used on operations that require dry air for example painting and sandblasting.
Refrigerated Air Dryer
This type of dryer works in the same way as that of the air conditioner. It is connected to the air compressor and allowed to cool the air to a particular temperature usually between 30-50 degrees Celsius. This will result in the formation of dew.
The water that gets out of the air is separated before the air is heated up and dispelled away. This, however, is not the cheap way of drying the compressed air although it the most crucial way of drying the system.
Types of refrigerated air dryers.
There are two configurations of refrigerated air dryers:
Non-cycling refrigerated air dryers
They work by;
Cooling the compressed air in a heat exchanger
Warming the compressed air as it travels in a unidirectional while exchanging with the moisture.
Reduce the temperature of the compressed air as refrigerant is heated
Regulate the flow of refrigerant as the heat load from the compressed air changes
Cool the compressed air through a heat exchanger medium like sand, metal or a fluid
Contain two heat exchangers fitted inside a tank that is filled with a thermal conducting fluid, such as water with propylene glycol added to prevent freezing and corrosion
Remove heat from the thermal conducting medium using the refrigeration system, then the compressed air is cooled by the thermal conducting medium
Cycle on when the fluid rises to its upper limit
Are designed to be more energy-efficient than non-cycling designs because refrigeration is only used to cool the heat exchanger medium and not the constant flow of hot air
Use a simpler refrigeration circuitry than non-cycling because hot gas bypass valves are not required
Desiccant Air Dryer
They work by removing water from the air in a desiccant air dryer. The air is allowed to circulate through the center of the vessels as it removes water. After the specific level of moisture is attained then the air is forced out of the dryer. They have two pressure tanks that work by recycling after 10 minutes to allow the tank to dry before again reworking for another time intervals.
While the drying time cycles, the fully pressurized compressed air flows through the online desiccant vessel through a bed of desiccant beads that strip the water vapor and hydrocarbon molecules from the air. The compressed air is released from the vessel when the specified PDP is reached.
During the regeneration cycle, the vessel depressurizes, and the regeneration process begins to heat the moisture out of the desiccant. After regeneration, the tank is pressurized again and ready for its next drying cycle.
Types of Desiccant dryers.
Quincy Desiccant Dryers
Quincy Compressor manufactures a full line of desiccant air dryer systems with dual towers that allow for purging — regeneration of the desiccant — in one tower while the other tower dries compressed air. This feature provides customers with longer use of the desiccant and continuous operation for extended periods, as in common in industrial environments.
Quincy offers four models of desiccant dryers to accommodate the various applications of air compressor systems.
The QHD Heatless Desiccant Dryer:
- Regenerates the off-line tower by using a small fraction of the dried compressed air
- Offers low maintenance costs and low initial cost
- Has an average-to-high operating cost?
The QDHP Heated Purge Desiccant Dryer:
- Regenerates the off-line tower with half the amount of the compressed air as compared to the heatless series
- Offers low maintenance costs and fairly low operating costs
- Has an average initial cost
- Cuts energy use by 50 percent with the optional Quincy Microburst Regeneration system
- The QDBP Blower Purge Desiccant Dryer:
- Regenerates the off-line tower by combining heat with ambient air
- Offers relatively low maintenance costs and operating costs
- Has a high initial cost
The QMOD Heatless Modular Desiccant Dryer:
- Regenerates the off-line tower with a small fraction of the dried compressed air
- Offers low maintenance costs and initial cost
- Runs with moderate-to-high operating costs
Deliquescent Air Dryers
It works by using a desiccant material that mixes with the compressed air to produce a liquid effluent that gets drained out and gotten rid of as waste. This type of dryers is not used in large industrial operations since the compressed air can be corrosive to the tank.
Piping System Air Drying
This is another way of cleaning the air compressor by inserting long pipes into the compressor to absorb some heat. As the air is heated and allowed to move along the pipes every moisture that is released is heated up and thus the compressor tank is dried.
Storage Tank Cooling Method
These tanks are u also known as reservoir tanks that are used in high-demand projects that demand a lot of compressed air within a short time. The air storage tank pressurizes the compressed air to keep it usable. Receiver tanks are also used to store the waste.
Wet storage method
Applies when the compressed air before undergoing the drying process is held. This paves room for the moisture to condense out of the compressed air before being dried up. The moisture is dried allowed out of the compressor.
The dried air is kept in the reservoir tank after drying to prevent any further accumulation of any additional moisture.
This method uses absorptive materials to absorb excess moisture. However, not commonly used the method is viable and efficient because it has low initial costs compared to other drying machines or methods. Its maintenance is cheap and low.
Air compressor tanks are useful when they are well maintained and are free from excessive water and moisture. However, water and moisture cannot be avoided but can only be minimized. So like any other machine, the air compressor needs to be regularly maintained to increase its efficiency and functioning.
