The dew point of the air adsorbed by the dry air generator is below -70 ℃

Purpose and Function:

Specially designed to provide high-purity dry air with a dew point of up to -60 ℃~-70 ℃ for the installation and maintenance of large power equipment such as transformers and reactors. It can replace traditional drying methods such as hot oil circulation, nitrogen supplementation, and vacuum pumping, and is more economical, safe, and environmentally friendly.
During the installation and maintenance of power equipment, it is not affected by changes in external climate conditions, especially overnight operations. All that is needed is to seal the flanges and fill them with dry air to reach 0.02-0.03Mpa, without the need for oil injection, nitrogen supplementation, vacuum pumping, etc. Transformers, reactors and other power equipment will not be affected by moisture, greatly reducing the workload and achieving the effect of shortening the construction period and improving the quality of installation and maintenance.

working principle

Under the action of an air compressor, the volume of air is compressed to 1/8 of its original size. At this point, the water vapor in the air reaches saturation, and most of the saturated water vapor condenses into liquid water in the storage tank and deposits at the bottom of the tank; Some small water droplets and particles flowing with compressed air are intercepted when passing through the first stage filter; The compressed air then enters the freezer, where the temperature drops to 4 ℃. The water vapor reaches saturation again and condenses into liquid water, which deposits inside the freezer; After passing through precision filters with filtration accuracies of 0.1 µ m and 0.01 µ m, the atmospheric dew point of compressed air is approximately -22 ℃; After entering the adsorption tower, water molecules in the air are adsorbed by strong composite molecular adsorbents, and other air components are discharged from the dry air generator. After adsorption, the dew point of the air is below -70 ℃, which is equivalent to a water content of 0.005 grams per cubic meter of air (the saturated water content in the air at 20 ℃ is 17.3 grams).

technical advantage

1. High extraction and recycling efficiency, diesel 86-88%; 2. Gasoline 5-6%; 3. Oil residue 6-8%

2. This system is an environmental protection, energy-saving, and waste oil regeneration project that benefits humanity;

3. After processing, this system produces the national standard 150-500N base oil (equivalent to Class II base oil of the American API standard).

4. Widely used for processing oil: suitable for various waste lubricating oils (including almost all recyclable waste oils such as gasoline and diesel engine lubricating oils);

5. Easy to operate, only 1-2 workers are needed to operate the machine.

6. There will be no secondary pollution during the processing: this process does not discharge any waste gas or wastewater

7. Very environmentally friendly, this machine is fully enclosed and will not release any harmful gases to the human body or the environment. The gum, asphalt, carbon black, and other waste lubricating oil will all turn into sludge, which can be used as asphalt or fuel.

8. The high-quality base oil obtained from production is free of unsaturated components, does not change color after long-term storage, and has no adverse odor. Good product quality: no oxidation discoloration, and no odor is produced.
