Abstract

The invention relates to a kitchen garbage thermal hydrolysis device and method. The device comprises a feeding balance section which is configured to receive materials and control the pressure in the feeding balance section to be a required value; a feeding port of the pyrohydrolysis tank is in on-off controllable connection with the feeding balance section, a discharging port of the pyrohydrolysis tank is in on-off controllable connection with the discharging balance section, and the pyrohydrolysis tank is configured to perform constant-pressure pyrolysis work; and the discharging balance section is configured to receive the pyrolyzed materials in the pyrohydrolysis tank and can control the pressure in the discharging balance section to be a required value. According to the scheme, the garbage can be pretreated in a continuous thermal hydrolysis mode, the defects of sequencing batch production are overcome, automatic production is facilitated, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a kitchen waste thermal hydrolysis device and method. Background technique [0002] Kitchen waste is an important part of domestic waste, including food residues generated in residents' lives and fruit and vegetable waste from farmers' markets. Kitchen waste has the characteristics of high moisture content, high organic matter content, high salt content and easy corruption. It contains a large number of pathogenic microorganisms such as Salmonella and Staphylococcus aureus, and also breeds pests such as flies and mosquitoes, which seriously affects the health of residents. and environmental hygiene. Then kitchen waste is rich in organic matter and has great potential for resource utilization. The resource utilization of kitchen waste is not only an important way to improve the recycling rate of domestic waste in my country, but also an important way to assist my c...
