Abstract

The invention relates to the technical field of treatment of kitchen waste, in particular to a kitchen waste hydrothermal three-phase separation system. In the kitchen waste hydrothermal three-phase separation system, a heating device is arranged on the outer wall of a hydrothermal reactor tank body and is a conduction oil coil pipe; the conduction oil coil pipe is clung to the side wall of a hydrothermal reactor to provide thermal energy for the kitchen waste, and the interior of the hydrothermal reactor is heated evenly; a thermal energy recovery device is arranged on a three-phase separator, and comprises a thermal energy recovery coil pipe arranged on the outer wall of a three-phase separator tank body, and a thermal energy recovery guide pipe connected with the thermal energy recovery coil pipe. According to the invention, the kitchen waste is heated by the conduction oil, so that the energy can be saved and the cost can be reduced; the kitchen waste is heated under a water condition to realize full hydrolyzation, and is discharged through jet explosion, so that the hydrolyzation is performed more thoroughly, and the subsequent utilization is facilitated. The three-phase separator integrates the functions of explosion bearing, flash vaporization and three-phase separation, and an outer water coil pipe is arranged for recovery of the thermal energy, so that the recycling of the thermal energy is realized, and the kitchen waste cannot be blocked at the same time.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, and more specifically, relates to a kitchen waste hydrothermal three-phase separation system, which is used for hydrothermal treatment and three-phase separation of kitchen waste. Background technique [0002] Food waste has the characteristics of high moisture content, high oil and organic matter content, and is a good raw material for refining biodiesel, fermenting feed, ethanol and other products. Since food waste mainly contains macromolecular organic substances such as starch, fat, and cellulose, it needs to be hydrolyzed into small molecular organic substances. The devices currently used for hydrolysis include explosion tanks and the like. The explosion tank is usually fed with steam to realize the high-pressure hydrolysis of organic waste, but the generation of steam requires high cost. At the same time, the water pipes for cooling and recovering heat energy are usually i...
