What are the technical advantages of waste heat regenerative dryers?

　　Energy saving and environmental protection have always been important development directions in the gas engineering industry. Gas consumption waste heat regenerative adsorption dryers have many technical advantages and fully comply with national energy saving and environmental protection.

　　1. The energy consumption of zero gas consumption waste heat regenerative adsorption dryers is almost negligible, and the whole machine is close to zero energy consumption.

　　2. Zero gas consumption waste heat regenerative adsorption dryer, consistent with the air compressor exhaust temperature, air compressor waste heat regeneration, the fan and heater do not need to participate in the regeneration process, there is no heater and fan power consumption, reducing the equipment failure rate caused by the fan and heater.

　　3. Zero air consumption compressed heat regenerative dryer adds a side line, if the equipment (mainly the drying tower) fails, immediately switch to the side line to ensure stable production and not affect the downstream gas requirements. The high-temperature compressed air discharged from the air compressor is cooled to below 40℃ through the cooler inside the dryer, the liquid water is separated through the air-water separator, and it is directly output to the later stage through the post-dust filter.

　　4. The compressed air pressure dew point has been at -20℃ for a long time without much fluctuation.

　　5. The PLC control system and large true color display can display various operating states and data curves, which greatly facilitates the user's on-site operation, management, and maintenance.

　　6. The optional Internet of Things system realizes intelligent control through remote real-time monitoring and fault alarms running on the operator's mobile phone.

　　Waste heat regenerative dryers use the heat generated when compressing gas to directly heat the adsorbent in the drying tower, causing it to decompose. We know that all compressors generate a large amount of compression heat when compressing gas, so after the compressor compresses the gas, a cooler must be used to cool the gas to room temperature before sending it to the downstream equipment for drying.

　　This will waste a lot of heat. Waste heat regenerative dryers utilize this part of the energy. Ensure that no compressed air is consumed during heating regeneration, only cold blowing consumes 2% of the drying compressed air, and the regeneration of the adsorbent is completely completed using the waste heat of the compressor (the compressor can also remove the cooler), and no blower and electric heater are needed. It can save 70% of energy. In today's energy crisis, it is an ideal energy-saving dryer.

　　Energy-saving effect analysis of gas consumption waste heat regenerative air dryers Compressed air is increasingly widely used in modern industry due to its safety and convenience. Due to the high reliability and civilized production required by modern industry, more and more customers need oil-free dust to purify compressed air. Compressed air requires energy consumption, and the air dryer consumes energy in the purification equipment.

　　Traditional waste heat regenerative dryers consume gas and electricity. Comprehensive calculations show that the energy consumption is higher than that of refrigeration dryers, but refrigeration dryers have irreplaceable advantages. That is, the gas exposure point is low and stable. Currently, common adsorption dryers mainly include non-heat regenerative dryers, heat regenerative dryers, and waste heat regenerative dryers.
