Why Choose Our Modular Type Adsorption Compressed Dry Air
① More Energy Saving
The air compressor desiccant dryer has low air consumption. The air consumption of the modular heatless dryer is generally 7%. But the double tower heatless dryer is generally 13%. علاوه بر این, its structure is simple. بنابراین, the air pressure loss is lower. Compared to traditional adsorption air dryers, it can reduce operation costs by 30%~60%.
② Stable Performance
The air compressor dryer system uses high-quality adsorbents. بنابراین, the performance of the air desiccant dryer is stable. It adopts a decentralized adsorption unit structure. It can greatly increase effective adsorption area. بدین ترتیب, the dew point is more stable.
③ More Hygienic
The main material is magnesium-aluminum alloy. همچنین, do anti-rust treatment by oxidation. بنابراین, it can effectively prevent secondary pollution. Especially suitable for the food and pharmaceutical industry. Life expectancy can be up to 30 سال ها.
④ Intelligent Control
This compressed dry air system uses PLC. It has a friendly human-computer interface. So it can realize remote control. The operation is simple and easy to understand. The air supply is continuous and stable. No intermittent air cuts.
⑤ Small Size And Light Weight
The overall structure is compact. Beautiful appearance design. The modular desiccant dryer is easy to transport and install. We can also install it in narrow spaces. So it does not take up a lot of production space.
بعلاوه, the modular adsorption dryer is not a pressure vessel. بنابراین, it doesn’t require annual re-inspection. Significant time and cost savings.
⑥ Low Later Maintenance Cost
اولا, fewer valves are used compared to the twin-tower air dryer. بنابراین, the failure rate is lower. Large desiccant dryers use air cylinders. Maintenance is simple and convenient. همچنین, the cost of the adsorbent is low. So there are fewer replacements later. مثلا, a 3.8m³/min heatless module air compressor desiccant dryer requires 35 adsorbents. But a 3.8m³/min heatless twin tower desiccant dryer requires 60KG adsorbents.
Why Modular Desiccant Air Compressor Dryer System is More Energy Saving
Take a 110KW air compressor as an example. The 5-year electricity consumption of several compressed dry air systems is as follows:
- ① Double tower heatless adsorption dryer: Air consumption is about 13%.
So energy consumption=11012436513%*5=CNY626340.
- ② Twin tower micro-heat regenerative air dryer: air consumption is about 7%. And the electric heating wire power is 4KW.
So energy consumption=1101243657%5+4124365*5=CNY512460.
- ③ Combination desiccant air compressor dryer system: The air consumption is 5%. The power of a refrigerated dryer is 4.5 کیلووات.
So energy consumption=1101243655%5+4.5124365*10=CNY438000.
- ④ Modular air compressor desiccant dryer: The air consumption is 5%. And the electricity consumption is 5 سال ها:
1101243655%*5=CNY240900.
The modular air compressor dryer system is composed of several cavities. It is equivalent to this situation: several small adsorption towers take adsorption simultaneously. So it can maintain a stable compressed air dew point.
And this structure has benefits. It increases the surface area where the adsorbent and compressed air contact. The contact time will also increase. بنابراین, the water absorption effect is multiplied. سرانجام, it greatly reduces the regeneration air consumption.
It is not like a traditional twin-tower compressed dry air system. The double-tower air dryer has a dead angle of adsorption. Short contact time with desiccant. بعلاوه, the contact is insufficient. Insufficient drying and regeneration. It needs much air to purge the adsorbents to achieve the dew point. از این رو, the regeneration air consumption is large.
How Does Modular Air Compressor Desiccant Dryer System Work
The heatless modular compressed dry air system has multiple aluminum cavities. Each group has two cavities. Each cavity is filled with desiccant beads. It’s to dry the moist compressed air. سپس, one cavity is working (drying), and beads will absorb moisture. در این زمان, the other side will regenerate by PSA.
During regeneration, some dry air expands to atmospheric pressure. Take away the moisture in the adsorbents. بنابراین, the desiccant beads can regenerate. We usually use it with a refrigerant dryer and precision filters. بدین ترتیب, it will enhance the performance and reliability of the air compressor desiccant dryer system.
When Group A is adsorbing, the intake valve A1 opens. همزمان, muffler exhaust valve B1 closes. The outlet check valve C1 of the air compressor desiccant dryer system also opens. Compressed air enters the downpipe from A1. سپس, enter the upper trachea after adsorption. The dry air flows to the air consumption section through C1. Part of the dry air enters Group B through regeneration valve D1. بنابراین, Group B started regeneration.
When Group B is regenerating, intake valve A2 is closed. Muffler exhaust valve B2 of the compressed dry air system opens. همزمان, the outlet check valve C2 closes. The regeneration air enters the upper air pipe through valve D2. The air performs analytical regeneration on the desiccant beads. سرانجام, it will discharge the moisture from the muffler exhaust valve B2.
How to Install Filters to Air Compressor Desiccant Dryer System
The filters can improve our compressed air quality. همزمان, it can protect our desiccant beads.
(1) Install The Pre-filter Before Adsorption Air Dryer
به این معنا که, install water-removal and oil-removal filters. Add them in front of the air compressor desiccant dryer system. If there is a lot of liquid water, it will affect the dryer effect. This results in an increase in the outlet dew point. علاوه بر این, oil mist can seriously pollute the desiccant beads. It will also raise the dew point. همزمان, it will shorten the service life of the adsorbent. After filtration, the liquid microparticle content will reach 0.01 μm. And the residual content of oil vapors will reach 0.01ppm.
(2) Install The Post-filter on The Compressed Dry Air System
The desiccant beads are under pressure and shock for a long time. It will generate some adsorbent dust. بنابراین, we need to ensure the quality of the downstream compressed air. سپس, installing the post-filter on the air compressor desiccant dryer system is necessary. اینجا, we use the dust-removal filter.
