Compression Heat Dryer

Overview

Yipu Compressed Heat Dryer achieves three core breakthroughs through innovative compressed heat utilization technology:

1. Zero Additional Energy Consumption: Fully utilizes waste heat from air compressors, requiring no external energy for regeneration—reducing annual operating costs by over 60% compared to traditional equipment.
2. Deep and Stable Drying: Delivers a pressure dew point of -70℃, meeting the most stringent process requirements with dew point stability far exceeding conventional dryers.
3. Rapid Investment Payback: Typically recovers equipment investment within 1-2 years, offering significant long-term operational benefits.

This product is particularly suitable for large air compressor stations with annual operating hours exceeding 6,000 hours, serving as the preferred solution for deep energy-saving upgrades of compressed air systems.

I. Market Pain Point Analysis

1. Massive Energy Consumption of Traditional Dryers
   • Heated regenerative dryers require additional electrical energy for heating, resulting in high electricity costs.
   • Heatless regenerative dryers consume 15-20% of finished compressed air, causing severe waste.
2. Low Comprehensive Energy Utilization Efficiency
   • High-temperature exhaust air (110-150℃) from air compressors is directly discharged, leading to significant energy waste.
   • Enterprises face persistently high energy costs and large carbon emissions.
3. Unreliable Dew Point Stability
   • Conventional dryers exhibit unstable dew points when load fluctuates.
   • This compromises the quality of high-end manufacturing and precision processes.

II. System Process Flow

Compressed Heat Utilization System:

1. Direct Utilization of High-Temperature Compressed Air
   • High-temperature air (110-150℃) discharged from the air compressor directly enters Adsorption Tower A.
   • The adsorbent maintains excellent adsorption performance under high-temperature conditions.
2. Synchronous Adsorption and Regeneration
   • While Tower A performs adsorption and produces dry air, Tower B uses waste heat from the system for regeneration.
   • Regenerated gas is discharged after cooling and separation.
3. Intelligent Switching Control
   • PLC controls automatic switching with an 8-hour standard cycle.
   • Optional dew point meter control enables on-demand regeneration.
4. Waste Heat Recovery System
   • Built-in high-efficiency heat exchanger fully utilizes compressed heat.
   • Optional auxiliary electric heating for extreme working conditions.

III. Working Principle

Temperature Swing Adsorption (TSA) Mechanism:

• Utilizes the adsorbent’s varying adsorption capacity at different temperatures.
• Adsorption capacity decreases at high temperatures, enabling deep regeneration.
• Adsorption capacity increases at low temperatures, ensuring deep drying.

Direct Compressed Heat Utilization:

• Exhaust heat from the air compressor is directly used for regeneration, requiring zero additional energy.
• Regeneration air consumption ≤6%, far lower than traditional equipment.

IV. Core Competitive Advantages

1. Ultimate Energy-Saving Effect
   • Zero external energy consumption for regeneration.
   • 100% more energy-efficient than heated regenerative dryers and over 50% more efficient than heatless regenerative dryers.
2. Stable Deep Drying
   • Pressure dew point stably maintained at -40℃ to -70℃.
   • Combined adsorption bed design ensures high-temperature adsorption capacity.
3. Intelligent Control System
   • PLC programmable control with remote monitoring support.
   • Multiple safety protections for reliable operation.
4. Long-Life Design
   • Unique air distribution device prevents adsorbent pulverization.
   • High-quality valves with a switching service life of up to 1 million cycles.
