AI Technical Summary

Technical Problem

The molecular sieve adsorption tower structure of the existing air compressor waste heat recovery air separation unit is not convenient for noise reduction treatment, resulting in poor noise reduction effect.

Method used

A cover is installed on the outside of the molecular sieve adsorption tower, and a flexible airbag is filled between the cover and the molecular sieve adsorption tower. Combined with a pressure monitoring sensor, solenoid valve and air pump device, the air pressure of the flexible airbag is controlled by inflation and deflation. The flexible airbag, sound-absorbing and breathable plate and fiber filling layer are used for sound absorption.

Benefits of technology

It effectively improves the noise reduction effect of molecular sieve adsorption tower, reduces noise pollution, and extends the service life of molecular sieve.
