<p>PURPOSE:To enhance heat exchange amount per unit adsorbent, by heating a zeolite type adsorbent while bringing the heated adsorbent into direct contact with a heating medium such as water or steam to perform heat exchange. CONSTITUTION:At least a part of the adsorbed water of a zeolite type adsorbent is released to regenerate said adsorbent. Steam is adsorbed with this zeolite type adsorbent bed and the temp. of said adsorbent bed is raised by the generated heat of adsorption. Subsequently, a heating medium comprising water, steam or a gaseous mixture containing steam is supplied and brought into direct contact with the adsorbent to perform heat exchange. Because adsorption heat is again generated at this time, the quantity of heat to be recovered is increased. In the next step, heated steam is withdrawn from the adsorbent bed.</p> |
