Title:
HYDROTHERMAL TREATMENT DEVICE, BIOMASS FUEL MANUFACTURING PLANT, HYDROTHERMAL TREATMENT METHOD, AND BIOMASS FUEL MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/239915
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce the water content of treated matter after a hydrothermal treatment, and reduce the energy required when separating and removing water from the treated matter after the hydrothermal treatment. A hydrothermal treatment device (3) for heating and thereby performing hydrothermal treatment on high-water-content biomass, wherein the hydrothermal treatment device (3) is provided with: a treatment container (21) for storing a sludge; a sludge feed unit (22) for feeding the sludge into the treatment container (21) so as to form a space (S) in the vertically upper section of the treatment container (21); a stirrer (23) provided in the treatment container (21), the stirrer (23) stirring stored matter so that a counter flow is produced in the vertical direction; and heat transfer tubes (24) disposed in the treatment container (21) in the horizontal direction, the heat transfer tubes (24) heating the sludge by means of heat of water vapor flowing therein.
