Introduction to the drying technology of compressed air dryer

By drying and filtering the compressed air by the freeze dryer, a large amount of water, oil and dust contained in the compressed air can be effectively eliminated to purify the air.

Environmentally friendly, energy-saving, and efficient freeze-drying technology - a well-designed multi-stage heat treatment system that fully considers the user's consideration to prevent high-temperature and humid environment and ensure efficient performance of the whole machine. First, the high temperature (can directly input high temperature gas of 80 °C) humid inlet compressed air is cooled by the rear cooler, the temperature of the high temperature gas drops to a certain extent, enters the second stage treatment system - heat exchanger, and the heat exchanger inlet and outlet adopts In the reverse design, the temperature is again lowered after the inlet air exchanges heat with the chilled outlet low temperature air. After two cooling treatments, the low temperature air flows through the evaporator to absorb heat and condense, and the evaporator uses secondary freezing. The heat transfer area is increased on the basis of standard design, and the heat conduction efficiency is better, which ensures the stability of the dew point and exchange. The efficiency is obviously improved, and energy is saved effectively. After the condensed compressed gas passes through the gas-liquid separator, it enters the second-stage heat exchanger and exchanges heat with the inlet compressed gas to output it; ensuring continuous operation in a harsh environment and increasing the outlet temperature to avoid the pipeline junction. Dew, affecting the working environment.

“Super” cyclone gas-liquid separator – mixed compressed air that is cooled by post-cooling, pre-cooling and refrigeration systems to form ice-cold compressed air and condensed oil, condensed water passes through a cyclone gas-liquid separator, and the cyclone generates intense The centrifugal force completely separates the air, condensed oil and condensed water, and the condensed oil water is discharged out of the machine through the automatic sewage system. The water removal efficiency is higher than 99.9%; compared with other condensed oil, water natural discharge, filtration discharge or interception discharge, etc. The output air drying efficiency is 50% higher, and its water removal capacity is almost constant under the condition that the air system pressure is low and the supply air pressure is unstable.

The advantages of the refrigerated compressed air dryer are “maintenance-free” sewage system – maintenance-free sewage system, professionally designed, and the diversion oil and water are quickly discharged from the gas-liquid separator by the diversion pipe to prevent the water from flowing back with the gas, and the design is generally Accumulating impurities in the accumulated storage space eliminates the need for regular cleaning and troublesome installation, prevents the electronic drainer from being blocked, and is equipped with a high-quality electronic drain valve, so that the sewage system can efficiently and automatically remove the separated condensed water and oil under long-term working conditions. Automatic sewage disposal does not require special personnel to guard, pre-plan, to avoid worries.

Compressed air dryers are widely used in many industries and fields, and refrigerated dryers have outstanding advantages in the high dew point range. At present, there are many applications of by-pass compressed air dryers in the domestic market, and there are many experts. And scholars have done a lot of research work on this.
