Embodiment Construction

[0037] The invention provides a sludge hydrothermal drying treatment device and a homogeneous reactor thereof, which can continuously perform hydrothermal drying treatment on sludge and improve the hydrothermal drying efficiency.

[0038] 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.

[0039] 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 in...

Abstract

The invention provides a sludge water heat drying treatment device and a homogeneous reactor thereof. The sludge water heat drying treatment device comprises the homogeneous reactor, the slurry reactor, a hydrothermal reactor and a flashing reactor which are sequentially connected. The homogeneous reactor is used for chopping and agitating materials, then the materials are delivered to the slurry reactor for even preheating, hydrothermal reaction is conducted to the preheated materials in the hydrothermal reactor, the materials are stored in the flashing reactor and the recovered steam of the flashing reactor can be fed into the slurry reactor and / or the hydrothermal reactor. When the sludge water heat drying treatment device is under certain temperature and pressure, viscous organic matters in sludge are hydrolyzed, the colloid structure of the sludge is destructed and bond water is facilitated to be separated from solid particles. The homogeneous reactor can chop and evenly agitate the materials and can ensure sludge water heat drying treatment to be uninterruptedly conducted.

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 homogeneous 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 resour...
