Compressed air dryer

Remove the set regeneration heater, no consumption of electricity, saving energy required for regeneration.

Introduction:

Waste heat regeneration compressed air dryer is the use of compressed air drying absorber air compressor gas energy conversion when the heat generated by direct heating or hot compressed air  to regeneration of the desiccant air drying equipment; no regeneration heater, gas consumption is regenerationless, the greatest degree of conservation of energy.

This equipment adopts PLC automatic control, simple, safe and reliable, renewable gas consumption is small, stable dew point, dew point requirements may be set according to the duty cycle and so on.

 

Work Principle:

High temperature air from a centrifugal compressor into the first state in the regeneration of adsorber, the adsorbent of the adsorber temperature desorption from the adsorber into the back of the cooler after it is cooled down to room temperature water, after cooling, a large number of compressed airhydrogel formed in the gaseous liquid discharged through the drainage and then into the vapor-liquid separator to further separate the compressed liquid water, greatly reducing the work load adsorber adsorption. And then into the adsorber in the adsorption state of drying, to obtain the dew point of about -40 °C dry air. Adsorbent adsorber regeneration state when heated to a certain time, the adsorbent has reached a certain temperature, stop heating, the blowing cold at the same time to switch the system piping, heat the compressed air directly into the back of the cooler is cooled down to room temperature water, the state entered in the regeneration of the cold blow drying adsorber, after blowing cold air after the adsorption state of re-entering the absorber is to dry, and then out of the system.

 

Features:

4h long period by switching mode, the whole general properties.

Complete regeneration process method used, recycled high-temperature heat using large flow of compressed air, can be very thorough regeneration of adsorbent

Remove the set regeneration heater, no consumption of electricity, saving energy required for regeneration.

Step sequence to increase the cold wind, making the outlet air dew point is stable and effective to ensure air quality.

Device integration, the whole factory.
