Embodiment Construction

[0049]The invention provides a sludge hydrothermal drying treatment device and a slurrying reactor thereof, which can continuously perform hydrothermal drying treatment on sludge and improve the hydrothermal drying efficiency.

[0050] figure 1 It is a structural schematic diagram of the sludge hydrothermal drying treatment device of the present invention. Such as figure 1 As shown, the sludge hydrothermal drying treatment device of the present invention includes a homogeneous reactor 101 , a slurry reactor 102 , a hydrothermal reactor 103 and a flash reactor 104 connected in sequence.

[0051] Wherein, the homogeneous reactor 101 includes a first reactor tank and a first agitator extending into the first reactor tank. The first material inlet 111 of the homogeneous reactor 101 is arranged at the bottom of the first reactor tank body, and the first material outlet 112 is arranged at the upper part of the side wall of the first reactor tank body. The sludge material is input...

Abstract

The invention provides a sludge hydrothermal drying treatment device and a slurry reactor of the device. The sludge hydrothermal drying treatment device comprises a homogeneous reactor, a slurry reactor, a hydrothermal reactor and a flash evaporation reactor which are connected sequentially. The homogeneous reactor cuts up and mixes materials, then inputs materials into the slurry reactor to pre-heat uniformly, the pre-heated materials are subjected to hydrothermal reaction in the hydrothermal reactor and are stored in the flash evaporation reactor; and the steam recovered by the flash evaporation reactor can be introduced into the slurry reactor and / or the hydrothermal reactor. The sludge hydrothermal drying treatment device of the invention can hydrolyze the viscous organic materials in the sludge under certain pressure and temperature, destroy the colloidal structure of the sludge, and drive the bound water and the solid grains to separate. The slurry reactor of the invention can uniformly mix and pre-heat the materials, so as to ensure the uninterrupted running of the sludge hydrothermal drying treatment.

Description

technical field [0001] The invention relates to the technical field of sludge hydrothermal drying treatment, in particular to a sludge hydrothermal drying treatment device and a slurrying reactor thereof. Background technique [0002] With the rapid development of the global economy and people's increasing concern for the environment, the amount of sewage treatment has increased rapidly, leading to the rapid expansion of sludge production. At present, my country's annual discharge of dry sludge is about 5 million tons, and the amount is still increasing. Improper sludge treatment will cause serious secondary pollution, and the investment and operation costs of sludge treatment are huge, accounting for 25% to 65% of the investment and operation costs of the entire sewage plant, which has become a heavy burden for urban sewage treatment plants. Therefore, how to dispose of excess sludge economically and efficiently, and realize sludge stabilization, harmlessness, and resource...
