PREVIEW METHOD OF BREAKING OUT OF UNNECESSARY INGREDIENTS IN GAS SEPARATION BY PRESSURE DIFFERENCE, ADSORPTION AND DESORPTION

摘要

PURPOSE:To perform an extremely correct control by providing two temp. sensors at the outlet of an absorbent layer, by converting the temp. rise caused by the heat of adsorption of unnecessary ingredients into an electrical signal and by indicating said signal outside. CONSTITUTION:Two temp. sensors are inserted apart each other around the outlet of the absorbent layer and the temp. difference between both sensors is measured. When gas flows through the adsorbent layer the attainable temp. of the front of the adsorption band spectrum is raised, and after said front passes by the temp. turns back to the former one, thus the front position of the adsorption band sectrum of unnecessary ingredients can be recognized. And, the temp. difference is converted into the electrical signal, which is fetched and amplified in order to actuate a solenoid valve and to control the cycle correctly.
