Micro-Heat Adsorption Dryer

Overview

Through innovative micro-thermal regeneration technology, Yipu Micro-Thermal Regenerative Adsorption Dryer delivers three core values to users:

1. Optimal Comprehensive Energy Efficiency: Achieves the perfect balance between regeneration air consumption and electrical energy consumption, reducing annual operating costs by 25%-40% compared to heatless regenerative dryers.
2. High Equipment Reliability: Long-cycle design significantly reduces valve operation frequency, extending the service life of key components by over 50%.
3. Superior Drying Quality: Stable low dew point output ensures process quality, with multiple dew point grades meeting different precision requirements.

This product is particularly suitable for enterprises with high compressed air quality requirements, moderate air consumption, and a focus on comprehensive operating costs. It serves as an ideal upgrade and replacement for traditional heatless and heated regenerative equipment.

I. Market Pain Points

1. Difficulty in Balancing Energy Consumption and Performance
   • Heatless regenerative equipment has high air consumption (20%-25%) and high operating costs.
   • Although heated regenerative equipment has low air consumption, it consumes enormous electrical energy for heating.
   • Users face a difficult trade-off between drying performance and operating costs.
2. Equipment Reliability Issues
   • Heatless regenerative equipment requires frequent switching (10-minute cycles), leading to severe valve wear.
   • Long-term frequent switching increases equipment failure rates and maintenance costs.
3. Insufficient Dew Point Stability
   • Conventional drying equipment exhibits unstable dew points when load fluctuates.
   • This affects the consistency of precision production process quality.

II. System Process Flow

Four-Process Cycle System:

1. Adsorption Drying Process
   • Compressed air (0.6-1.0MPa, ≤45℃) enters Adsorption Tower A.
   • Activated alumina or molecular sieve deeply adsorbs moisture.
   • Dry air with a pressure dew point of -20℃ to -70℃ is produced.
2. Heated Regeneration Process
   • Approximately 7-10% of the dry air is heated by an electric heater.
   • Hot air (about 150-180℃) enters Tower B to deeply regenerate the adsorbent.
   • Moisture inside the adsorbent is completely removed.
3. Cold Purge Cooling Process
   • Heating is stopped, and the regenerated tower is purged with normal-temperature dry air.
   • The adsorbent temperature is reduced to the operating temperature range.
   • Ensures adsorption performance for the next cycle.
4. Pressure Equalization and Switching Process
   • At the end of the 2-6 hour cycle, pressure equalization is performed between the two towers.
   • The microcomputer control system automatically switches operating states.

III. Technical Principle

Micro-Thermal Regeneration Mechanism:

• Uses a small amount of thermal energy to significantly reduce regeneration air consumption.
• Heating temperature is controlled within the optimal regeneration temperature range of the adsorbent.
• Balances the economy of thermal energy input and compressed air consumption.

Intelligent Control Strategy:

• Automatically optimizes cycle time based on inlet conditions and dew point requirements.
• Heating power is automatically adjusted according to ambient temperature.
• Achieves optimal balance control between energy consumption and drying performance.

IV. Core Competitive Advantages

1. Outstanding Energy-Saving Effect
   • Regeneration air consumption: 7%-16%, 30%-60% lower than heatless regenerative dryers.
   • Long-cycle design (2-6 hours) minimizes equipment wear and extends service life.
2. Stable Low Dew Point Output
   • Pressure dew point can reach -70℃, meeting high-end application requirements.
   • Combination of activated alumina and molecular sieve ensures deep drying.
3. Intelligent Operation Management
   • Fully automatic microcomputer control realizes optimal energy efficiency operation.
   • Fault self-diagnosis system facilitates convenient maintenance.
4. Flexible Application Configuration
   • Three dew point grades available to adapt to different process requirements.
   • Wide processing capacity range (1.2-110 Nm³/min) covers various scales.

V. Technical Strength
