Problems solved by technology

[0004] However, the inventor believes that there are still some problems in the traditional treatment method: one is that the sludge concentration tank causes poor sludge settlement effect; the other is that there is no corresponding tail gas treatment system and dust treatment system, and the surrounding environment of the sludge treatment device is poor; The third is that there is no blending ratio system, resulting in uneven blending

Embodiment 1

[0055] refer to figure 1 , a sludge settling device, comprising: a shell 1, a cylinder body 2, a water inlet pipe 3, a baffle plate 4, a guide plate 5, a water outlet groove 6 and a mud outlet 7, wherein: the shell 1 has an empty The structure of the cavity, the cylinder body 2 is arranged inside the casing, one end of the cylinder body is open, the other end is closed, and the open end is set downward, the water inlet pipe 3 is arranged in the cylinder body 2 and is located at the upper part of the cylinder body, Water inlet holes are distributed on the wall of the water inlet pipe, and the port of the water inlet pipe at one end of the cylinder body 2 is closed; the baffle 5 is a horn-shaped structure, which is connected to the open end of the cylinder body 2 at At the same time, the larger end of the opening of the trumpet-shaped structure is arranged downward; the deflector 6 is a spherical cap-shaped structure, which is arranged below the baffle 5; In order to facilitate...

Embodiment 2

[0057] A sludge settling device, the same as Embodiment 1, the difference is: the upper part of the casing 1 is a cylinder, the lower part is a cone, the mud outlet 7 is located at the tip of the cone, and the height of the cylinder is is 4000mm, the height of the cone is 4000mm, the diameter of the cylinder 2 is 500mm, and the height is 1500mm; the diameter of the spherical cap is 500mm, and the ratio of the center height to the diameter of the spherical cap is 0.05.

Embodiment 3

[0059] A sludge settling device, the same as the second embodiment, the difference is: the height of the cylinder is 7000mm, the height of the cone is 7000mm; the diameter of the cylinder 2 is 600mm, the height is 2500mm; the diameter of the spherical cap is 600mm, the ratio of the center height to the diameter of the spherical cap is 0.15; the angle between the inclined plane of the baffle 4 and the horizontal plane is 50°; the diameter of the spherical cap is the same as the diameter of the baffle; The vertical distance between the bottom surface and the bottom surface of the baffle is 0.8m.

Abstract

The invention belongs to the technical field of sludge treatment, and in particular relates to a sludge recycling and harmless treatment device, process and application; the treatment device includes a sludge settling device, a sewage treatment system, a centrifugal dehydrator and a sludge granulator , drying machine, dry silo, induced draft device and incinerator; wherein, the water outlet of the sludge settling device and the sewage treatment system, the sludge outlet of the sludge settling device and the centrifugal dehydrator, the centrifugal The water outlet of the dehydrator is connected to the sewage treatment system, and the sludge outlet of the centrifugal dehydrator is connected to the sludge granulator, and the sludge granulator, dryer and dry silo are connected in sequence; The dehydrator, the sludge granulator and the dryer are all connected with an induced draft device, and the induced draft device is connected with the incinerator. The invention can fully recycle and harmlessly treat the excess sludge generated in the biochemical sewage treatment system, and form industrial coal furnaces with different working conditions as fuel for mixed combustion, and the whole process takes less time.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a sludge resource harmless treatment device, process and application. Background technique [0002] The information disclosed in this Background of the Invention is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] With the expansion of more and more sewage treatment plants, the treatment of excess sludge produced by biochemical systems is difficult and prone to secondary pollution. The problems faced by the unit, in order to reduce the impact on the environment, the residual sludge is recycled, harmless and environmentally friendly. For example, the patent document 201810044345.5 discloses a sludge resource treatment method, which includes...
