Abstract

The invention discloses a multi-stage flashing sludge continuous hydrothermal treatment device, and the multi-stage flashing sludge continuous hydrothermal treatment device comprises a raw mud buffertank, a homogenization reactor, slurrying reactors, a hydrothermal reactor and flashing reactors which are sequentially connected. The number of the slurrying reactors is at least one, and the numberof the flashing reactors is at least two, the slurrying reactors are sequentially connected in series and the flashing reactors are sequentially connected in series. The homogenization reactor and theslurrying reactors arranged from front to back are also in one-to-one correspondence connection with the flashing reactors which are arranged from the back to the front. The multi-stage flashing sludge continuous hydrothermal treatment device is simple in equipment and process, the sludge treatment efficiency is high, and the energy consumption is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, relates to a modification treatment technology of municipal or industrial sludge, and in particular to a multi-stage flash sludge continuous hydrothermal treatment device. Background technique [0002] In recent years, the urbanization process has become faster and faster, and the generation and treatment rate of urban domestic sewage are also increasing. Although various methods have been adopted to reduce the output of urban sludge, the total amount is still at an annual rate of 10%. rate increments. Sludge from sludge treatment plants is generally "anaerobic digestion-dosing dehydration" to reach a moisture content of about 80%, and then transported to sanitary landfills for landfill. 80% of the sludge still has a certain fluidity, which brings inconvenience to the landfill operation, and there is a hidden danger of secondary pollution. As the state strengthens the final dispos...
