摘要： PURPOSE:To improve vaporizing performance by a method wherein a heating medium inlet piping forms a straight pipe, the length thereof is set to a value lower than the specified multiple of the bore of the outlet of an expansion valve and by forming an uneven surface in the inner surface of the heating medium inlet piping, a vapor-liquid phase is kept in a uniform state when a heating medium flows through the interior. CONSTITUTION:A heating medium of a vapor-liquid phase flow flowing through an outlet 1a of an expansion valve 1 flows through a heating medium inlet piping 3A, which is a straight pipe having the inner surface being uneven surface and has length 20 times or less as long as the bore of the expansion valve 1, to a heat exchanger inlet header 4. The heating medium of a vapor-liquid phase flow flowing in the heat exchanger inlet header 4 is equally distributed to a plurality of heat transfer pipes 7. Heat is imparted thereon from heating fluid 8 to vaporize the heating medium, which flows to a heat exchanger outlet header 9 and flows out through a heating medium outlet piping. By forming an uneven surface 5 in the inner surface of a heating medium inlet piping 3A, a liquid film 5 flowing on the inner wall of a pipe is apt to be scafferd. Mixture and uniformization of a vapor-liquid phase are further promoted, a heating medium of a vapor-liquid phase flow in the inlet header 4 of the heat exchanger is equalized in quality, distribution of a flow rate to a plurality of the heat transfer pipes 7 is further equalized, and vaporizing performance and heat transfer performance are improve.

摘要： PROBLEM TO BE SOLVED: To recover methane gas even from the excess sludge having a high content of difficult-to-decompose org. matter with high efficiency in the same way as for garbage by promoting the solubilization of the excess sludge by the heat, ultrasonic wave and lytic enzyme at the preceding stage to the stage of mixing the excess sludge with garbage and then mixing the solubilized sludge with garbage. SOLUTION: Excreta and septic-tank sludge are freed from the residue (S1) and then biologically treated by an activated-sludge device (S2), and the supernatant liq. is subjected to such complete treatment as flocculation and separation/ activated-carbon treatment and then discharged. Meanwhile, the excess sludge settled and removed by the biological treatment is concentrated in a concentration tank (S3), then the molecular weight lowering and solubilization of the cellulose, etc., contained in the excess sludge are promoted by the heat or ultrasonic wave by decomposing them to the org. acid or the like. Subsequently, the excess sludge and the crushed garbage obtained by crushing the garbage (S4) are charged into a mixing tank (S5) to mix the excess sludge and garbage and methane-fermented (S6). The produced methane is used to generate electric power (S7), and the digested sludge is composted (S9).
