Forced-air Dryer

Overview

Yipu Compressed Air Blower-Heated Regenerative Adsorption Dryer achieves three core values through innovative blower regeneration technology:

• Significant Economic Benefits: Regeneration air consumption is reduced to ≤5%, directly saving compressed air production costs; long-life adsorbent design lowers maintenance and replacement expenses.
• High Operational Reliability: PLC intelligent control ensures stable operation; activated alumina adsorbent features strong crush resistance.
• Excellent Application Flexibility: Wide flow range adapts to different scale requirements, and multiple dew point grades meet various process needs.

This product is particularly suitable for manufacturing enterprises with high compressed air quality requirements and large air consumption, serving as an ideal choice for energy-saving upgrading of compressed air systems.

I. Market Pain Point Analysis

1. High Energy Consumption and Operational Costs
   • Traditional heated regenerative dryers have regeneration air consumption as high as 8-15%, resulting in massive compressed air waste.
   • While heatless regenerative dryers do not consume electrical energy, their regeneration air consumption is even higher (12-18%).
2. Low Regeneration Efficiency
   • Traditional thermal regeneration methods have low heat utilization efficiency and incomplete regeneration.
   • Adsorbents have a short service life, requiring frequent replacement and leading to high maintenance costs.
3. Poor Dew Point Stability
   • Conventional dryers exhibit unstable dew points when load fluctuates.
   • This affects production process quality and equipment service life.

II. System Process Flow

Dual-Tower Alternating Adsorption-Regeneration System:

1. Adsorption Drying Stage
   • Compressed air (0.6-1.0MPa, ≤45℃) enters Adsorption Tower A.
   • It passes through a fixed bed of activated alumina, where moisture is deeply adsorbed.
   • Dry air with a pressure dew point of -20℃ to -70℃ is produced.
2. Blower-Heated Regeneration Stage
   • A blower draws ambient air (≤40℃, RH65%).
   • An electric heater heats the air to the regeneration temperature.
   • Hot air thoroughly regenerates the adsorbent in Tower B.
3. Cooling Stage
   • After regeneration, the system switches to using its own dry air for cooling.
   • The adsorbent temperature is reduced to the operating temperature, preparing for the next cycle.

Intelligent Control Flow:

• PLC program controls long-cycle switching (4-8 hours).
• A liquid crystal text display real-time monitors operating status.
• Automatic valves ensure precise process switching.

III. Technical Principle

Adsorption-Regeneration Equilibrium Mechanism:

• Utilizes the selective adsorption characteristics of activated alumina for moisture.
• The microporous structure of the adsorbent provides a large specific surface area (300-400m²/g).
• Thermal regeneration breaks the adsorption equilibrium, releasing adsorbed moisture.

Energy-Saving Regeneration Technology:

• Ambient air is used during the heating phase, avoiding compressed air consumption.
• A small amount of the dryer’s own dry air is used during the cooling phase to ensure regeneration quality.
• Regeneration air consumption ≤5%, far lower than traditional equipment.

IV. Core Competitive Advantages

1. Significant Energy-Saving Effect
   • Regeneration air consumption ≤5%, 50% lower than traditional equipment.
   • Long-cycle design (4-8 hours) reduces switching frequency.
2. Stable and Reliable Performance
   • Pressure dew point stably maintained at -20℃ to -70℃.
   • Activated alumina adsorbent with high mechanical strength and long service life.
3. Intelligent Control System

   • Liquid crystal text display provides user-friendly human-machine interaction.
4. Flexible Application Configuration
   • Wide flow range (6-200m³/min).
   • Multiple dew point grades available to meet different requirements.
