<p>PURPOSE:To preheat the liquid to be treated with the heat energy retained in treated liquid and to reduce the cost of heating, by providing a heat exchanger on a supply pipeline for the liquid to be treated to a digester, and conducting the treated liquid of a high temp. discharged from a digestion chamber thereto. CONSTITUTION:A heat exchanger 5 is assembled on a supply pipeline 3 for liquid to be treated connected to an anerobic digester 1. The high temp. side of the heat exchanger 5 is formed with a part of a delivery pipeline 6 for the treated liquid of a high temp. subjected to a decomposition treatment in the chamber 2. The heat energy retained by the treated liquid is thus effectively recovered in preheating the liquid to be treated that runs in the pipeline 3. The utilizing rate of a digester gas is improved by such device.</p> |
