Waste heat regenerative dryer It uses the high-temperature heat energy of the two-stage exhaust gas of the air compressor or uncooled high-temperature compressed air to perform deep desorption regeneration of the adsorbent, without the need to add a heat source, no reheating during heating, reliable operation, stable dew point. Let's learn about the working principle and application range of the waste heat regenerative dryer.

　　With the advancement of science and technology and the improvement of people's living standards, the requirements for compressed air quality in industrial, food, and pharmaceutical fields are becoming increasingly higher. Currently, commonly used compressed air purification equipment mainly includes refrigeration dryers, heatless adsorption dryers, and micro-heat adsorption dryers.

　　I. Working Principle of Waste Heat Regenerative Dryer

　　The waste heat regenerative dryer mainly consists of three parts: a heat exchange system, a refrigeration system, and an electrical control system. The heatless adsorption dryer uses self-heating for adsorption drying based on the pressure swing adsorption regeneration cycle principle. The waste heat regenerative dryer adds a heater on the basis of the heatless adsorption dryer, and uses the gas flow for regeneration after increasing the temperature to heat and regenerate the desiccant.

　　II. Energy Consumption Analysis of Waste Heat Regenerative Dryer

　　The waste heat regenerative dryer has high energy consumption, due to partial electricity consumption and partial circulating cooling water consumption, the energy consumption of new energy facilities is also considerable; low energy consumption, but high regeneration gas energy consumption, and a significant increase in air compressor energy consumption; electricity consumption is mainly the micro-heat of reactivation. Due to the relatively long cycle of micro-heat, this greatly reduces the energy consumption of the waste heat regenerative dryer, and the reactivation consumption is small, so the air conditioner at the corresponding price has a great advantage in terms of comprehensive energy consumption. Micro-heat adsorption dryers have a significant advantage in the field of compressed air purification.

　　The applicable range of the waste heat regenerative dryer is as follows.

　　To reduce the gas consumption of the four types of cycle time adjustments to meet the needs of different outlet dew points

　　Further adjust the gas flow to meet the needs of different outlet dew points;

　　Filters, etc., can be installed on the front and back without changing the design;

　　Long lifespan of the waste heat regenerative dryer:

　　The adsorbent pressing device ensures the long cycle and utilization rate of the adsorbent, and the life of the desiccant exceeds 2-3 years

　　Selection of high-quality adsorbents and pneumatic components

　　Using stainless steel materials, durable and rust-proof

　　Quiet: Using standard scarves, good effect, easy to replace, low noise

　　Stable: The controller design considers small pressure and flow fluctuations downstream

　　Low power consumption: If the low power consumption outlet dew point can be improved, it is reduced, the gas flow is adjusted, and the gas consumption is reduced

　　Easy to maintain: There are adsorbent filling holes and outlets for easy replacement; the detachable stainless steel diffuser is easy to clean

　　Application range of waste heat regenerative dryers: ozone generators, packaging machinery, coating equipment, three-coordinate measuring machines, vacuum cleaners, testing equipment, plastic dryers, cable inflators, microwave systems, radar systems, broadcast transmission systems, medical and dental equipment, pneumatic components and instruments.
