Embodiment 1

[0036] Embodiment 1: as figure 1 As shown, according to an exemplary embodiment of the present invention, the hydrothermal reaction device includes a housing 1, and the housing 1 includes a cylinder body 2 and a head 3. In this embodiment, the cylinder body 2 and the head 3 are detachable through a flange 4 The two partitions 5 are arranged in the shell 1, and the two partitions 5 separate the three material channels 6 in the shell, in order to meet the needs of the hydrothermal reaction , the number of partitions 5 inside the housing 1 can be selected according to actual needs; there is a gap for the passage of gas between the top of the partitions 5 and the top of the housing 1; a filter member 8 is arranged in the last channel, which is selected in this embodiment The filter part 8 is a filter screen, and the thick liquid outlet 9 and the clear liquid outlet 10 are respectively arranged on the wall of the housing 1 before and after the filter screen; the material inlet 7 is...

Embodiment 2

[0038] Embodiment 2: as figure 2 As shown, according to an exemplary embodiment of the present invention, the hydrothermal reaction system includes:

[0039] The material pump 12 is used to provide the power and pressure required for the material to flow in the hydrothermal reaction system;

[0040] The heat exchanger group is used to recover the heat of the liquid discharged from the hydrothermal reaction device 16 to heat the material supplied from the material pump 12; the heat exchanger group includes a first heat exchanger 13, a second heat exchanger 14 and an electric heater 15 , wherein the first heat exchanger 13 uses the heat of the concentrated liquid discharged from the hydrothermal reaction device 16 to heat the material supplied by the material pump; the second heat exchanger 14 utilizes the clear liquid discharged from the hydrothermal reaction device 16 to produce The heat of the liquid is used to heat the material heated by the first heat exchanger; the elect...

Embodiment 3

[0044] Embodiment 3: in combination with figure 1 , 2 As shown, a hydrothermal treatment method is processed by a hydrothermal reaction device and a hydrothermal reaction system. The specific method includes the following steps:

[0045] The external material enters the heat exchanger group through the material pump 12 for heating;

[0046] The heated material enters the hydrothermal reaction device 16 through the material inlet 7 to undergo a hydrothermal reaction, and the material flows through the multiple channels 6 separated by the partition plate 5 in sequence, and the organic components in the material are hydrolyzed; the material passes through the filter unit 8. The filtered clear liquid is discharged from the housing through the clear liquid outlet 10, and the concentrated liquid is discharged from the housing through the concentrated liquid outlet 9; the generated gas passes through the gap between the top of the partition and the top of the housing and then passes...

Abstract

The invention discloses a hydrothermal reaction device which comprises a shell, at least one partition plate is arranged in the shell and used for dividing the interior of the shell into a plurality of channels, and a gap for gas to pass through is reserved between the top of the partition plate and the top of the shell; a material inlet is formed in the bottom of the shell, and materials sequentially flow through all the channels after entering the shell; a filtering part is arranged in the most downstream channel, a concentrated liquid outlet is formed in the wall of the shell at the upstream of the filtering part, and a clear liquid outlet is formed in the wall of the shell at the downstream of the filtering part; and an exhaust hole for exhausting gas is formed in the top of the shell. The device is small in occupied area and compact in structure; and the hydrothermal reaction system is combined, two-stage recovery of heat is achieved, gas generated by the hydrothermal reaction device pushes the expansion machine so as to drive the power generator to generate power, energy generated by hydrothermal reaction is fully utilized, cyclic utilization is achieved, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the field of hydrothermal reaction, in particular to a hydrothermal reaction device, system and hydrothermal treatment method. Background technique [0002] At present, a large amount of water-containing organic waste is produced in production and life, including domestic organic waste, municipal sludge and industrial sludge. Its output is huge, its calorific value is low, its water content is large, and it contains a variety of organic pollutants and heavy metals. Harmless treatment Difficult to use. [0003] At present, composting, landfilling and incineration are the common methods to deal with domestic waste and municipal sludge. When composting materials are used, it is usually necessary to add conditioners to reduce the water content to 50% to 60%. Taking municipal sludge as an example, composting requires The total amount of conditioner added is about 60% of the sludge, and the amount of solids to be disposed of has not...
