The Heated Regeneration Adsorption Dryer works according to the principle of temperature swing adsorption, that is, the adsorbent absorbs moisture at room temperature, and the moisture adsorbed by the adsorbent completes "desorption" at high temperature and returns to the air phase. in this process, an extemal heat source provides the heat required for desorption, and uses part of its product air as a heat carier.
In the heating regeneration process, all the adsorbed water retums to the air phase, which does not mean that the adsorbent regeneration has been completed. The original adsorption activity is fully restored when the temperature is lowered to the initial value.
Therefore, the regeneration process of the micro-heat regeneration adsorption dryer must be caried out in two steps, that is "heating and desorption" first, and then "cooling and regeneration", "desorption" is only one step of adsorbent regeneration.
