Title:
HYDROTHERMAL TREATMENT DEVICE AND HYDROTHERMAL TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/113762
Kind Code:
A1
Abstract:
A hydrothermal treatment device (10) includes a sealed container (11), a temperature measurement device (18) for measuring the internal temperature of the sealed container (11), an introduction pipe (14) for introducing water vapor into the sealed container (11), a solenoid valve (15) disposed in the introduction pipe (14), a decompression device (17), and a control device (19). After waste containing organic matter is charged to the sealed container (11), the control device (19) performs a control in the manner described below to cause a hydrothermal reaction in the waste containing organic matter. Namely, after the internal temperature is raised to a first temperature, the first temperature is held for a first length of time and then made to fall, the internal temperature thus decreases from the first temperature to a second temperature, the second temperature is subsequently held for a second length of time (a length of time equal to or longer than the first length of time) and then made to rise, the internal temperature thus reaches a third temperature equal to the first temperature, the third temperature is subsequently held for a third length of time similar to the first length of time, and the temperature is then made to fall.
