Embodiment 1

[0054] Embodiment 1: as Figure 1-Figure 4 As shown, a kind of sludge slurry hydrolysis integrated treatment equipment of the present invention comprises:

[0055] A cold sludge chamber 1, the cold sludge chamber 1 is used to import cold sludge to be treated; the cold sludge includes municipal sludge and other organic sludge;

[0056] The hot sludge chamber 2, the sludge treated by the cold sludge chamber 1 enters the hot sludge chamber 2;

[0057] A sleeve-shaped wrapping structure is adopted between the cold sludge chamber 1 and the hot sludge chamber 2, and the cold sludge chamber 1 and the hot sludge chamber 2 perform heat exchange to complete slurrying and hydrolysis treatment of sludge.

[0058] In this embodiment, the cold sludge chamber 1 is wrapped on the outside of the hot sludge chamber 2 . The cold sludge to be treated is sent into the cold sludge chamber 1, and the sludge sent from the cold sludge chamber 1 is sent into the hot sludge chamber 2. The hot sludge ch...

Embodiment 2

[0089] Embodiment 2: as Figure 5-Figure 8 As shown, the difference from Example 1 is that in this example, the hot sludge chamber 2 is wrapped on the outside of the cold sludge chamber 1 . The cold sludge to be treated is sent into the cold sludge chamber 1, and the sludge sent from the cold sludge chamber 1 is sent into the hot sludge chamber 2. The hot sludge chamber 2 is used for heat exchange with the cold sludge chamber 1, that is, the cold sludge chamber 1 will absorb the heat of the wrapped hot sludge chamber 2; while the hot sludge in the hot sludge chamber 2 is gradually cooled After the sludge chamber 1 absorbs heat, it can be lowered to the appropriate temperature required by the back-end process, reducing the cooling mechanism in the traditional processing equipment, which not only improves the overall efficiency of the system but also reduces the energy consumption of the system.

[0090] In this example, the hot sludge chamber 2 and the cold sludge chamber 1 ca...

Embodiment 3

[0098] Embodiment 3: as Figure 9-Figure 11 As shown, in this example, the structure in which the hot sludge chamber 2 wraps the cold sludge chamber 1 is also adopted, and its basic structure and process route are basically the same as those in Example 2, except that: the vertically arranged from top to bottom The middle part of the cold sludge chamber 1 is pierced with several communicating pipes, which are only used to allow the sludge in the hot sludge chamber 2 to pass through, but will not mix with the sludge in the cold sludge chamber 1 . In the present invention, an internal circulation agitation device is further provided at the position corresponding to the communication pipe in the hot sludge chamber 2, and the heat circulation agitation device can generate suction or propulsion effects to complete the flow of hot sludge in the communication pipe. In this way, the heat exchange capacity can be greatly enhanced, the uniform heat effect of the heat exchange can be impr...

Abstract

The invention discloses an integrated sludge pulping and hydrolyzing equipment, comprising a cold sludge cavity into which the cold sludge to be treated is delivered; a hot sludge cavity into which the sludge treated by the cold sludge cavity enters; wherein a sleeve-type wrapping structure is applied between the cold sludge cavity and the hot sludge cavity, and heat exchange is conducted to pulp and hydrolyze the sludge between the cold sludge cavity and the hot sludge cavity. The equipment provided by the present invention is simple in structure principle, small in floor space, high in treatment efficiency and good in treatment effect.

Description

technical field [0001] The invention mainly relates to a sludge treatment system, in particular to a sludge slurrying and hydrolysis integrated treatment equipment capable of treating sludge continuously, efficiently and with low energy consumption. Background technique [0002] With the rapid development of the economy, the continuous improvement of living standards, the strengthening of human awareness of the environment and the increasing requirements for environmental quality, more and more types of wastewater need to be treated. [0003] There have been breakthroughs in wastewater treatment technology in the past few decades. However, due to the widespread phenomenon of "heavy water and light mud" in the construction of sewage treatment plants, a large amount of sludge "backlogs" has not been properly and safely disposed of. Therefore, compared with the relatively mature sewage treatment technology, the sludge treatment and disposal technology is still in the stage of ...
