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%. 此外, its structure is simple. 所以, 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. 所以, the performance of the air desiccant dryer is stable. It adopts a decentralized adsorption unit structure. It can greatly increase effective adsorption area. 因此, 露點更穩定.
③ More Hygienic
The main material is magnesium-aluminum alloy. 也, do anti-rust treatment by oxidation. 所以, it can effectively prevent secondary pollution. Especially suitable for the food and pharmaceutical industry. Life expectancy can be up to 30 年.
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. 供氣持續穩定. 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.
除了, the modular adsorption dryer is not a pressure vessel. 所以, it doesn’t require annual re-inspection. Significant time and cost savings.
⑥ Low Later Maintenance Cost
首先, fewer valves are used compared to the twin-tower air dryer. 所以, the failure rate is lower. Large desiccant dryers use air cylinders. Maintenance is simple and convenient. 也, the cost of the adsorbent is low. So there are fewer replacements later. 例如, 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: 空氣消耗量約為 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 千瓦.
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 年:
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. 所以, the water absorption effect is multiplied. 最後, 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. 除了, the contact is insufficient. Insufficient drying and regeneration. It needs much air to purge the adsorbents to achieve the dew point. 所以, 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. 然後, one cavity is working (烘乾), and beads will absorb moisture. 此時, the other side will regenerate by PSA.
再生期間, some dry air expands to atmospheric pressure. Take away the moisture in the adsorbents. 所以, the desiccant beads can regenerate. We usually use it with a refrigerant dryer and precision filters. 因此, it will enhance the performance and reliability of the air compressor desiccant dryer system.
When Group A is adsorbing, the intake valve A1 opens. 同時, 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. 然後, 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. 所以, 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. 同時, 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. 最後, 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. 同時, it can protect our desiccant beads.
(1) Install The Pre-filter Before Adsorption Air Dryer
那是, 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. 此外, oil mist can seriously pollute the desiccant beads. It will also raise the dew point. 同時, it will shorten the service life of the adsorbent. After filtration, the liquid microparticle content will reach 0.01 微米. 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. 所以, we need to ensure the quality of the downstream compressed air. 然後, installing the post-filter on the air compressor desiccant dryer system is necessary. 這裡, we use the dust-removal filter.
常見問題解答
High-efficiency activated alumina + high-efficiency molecular sieve. Both are from China famous brand.
It is about 8000~12000 hours. The specific replacement time is based on the compressed air quality.
當然. There are two advantages to installing the compressed air filters. 首先, it can ensure the compressed air quality. 第二, it can extend the lifetime of desiccant dryer and adsorbent.
The dew point can be -20℃ and -40℃ for modular adsorption air dryers.
