Problems solved by technology

[0002] In the prior art, silt needs to be processed in three steps, silt cleaning, silt disposal, and silt absorption; in the process of silt cleaning, it has a greater impact on the aquatic environment and organisms, and it is prone to over-excavation or under-excavation. The dams cause harm; in the process of sludge disposal, the existing technology needs to be dehydrated and solidified, and then the storage yard is selected for pressure filtration. During the process of sludge solidification, more h...

Embodiment 1

[0036] The first object of the present invention is to provide a system for producing carbon mud by anaerobic pyrolysis of sludge. The system is arranged adjacent to the sludge source. The sludge source includes but not limited to rivers or lakes or ponds or reservoirs. The system includes a sludge suction device and an impurity removal device. , Dehydration device, material conveying device, anaerobic cracking and carbonization device, water inlet device, drainage device.

[0037] Anaerobic pyrolysis carbonization device, which includes a converter body 1, sludge feeding equipment composed of a feed hopper and a screw conveyor 4, mixed gas treatment equipment for processing mixed gas generated by anaerobic pyrolysis carbonization 2, and biomass particle processing equipment Exhaust gas treatment equipment for combustion exhaust gas, biomass pellet combustion equipment 3, and carbon mud cooling equipment.

[0038] The impurity removal device includes a vibrating grate for sepa...

Embodiment 2

[0048] In conjunction with embodiment 1, a kind of sludge anaerobic cracking carbon mud process, process steps are as follows:

[0049] The second object of the present invention is to provide a kind of silt anaerobic cracking carbon mud process, process steps are as follows:

[0050] The first step, suction mud: extract silt from river course or lake or pond or reservoir by suction device;

[0051] The second step, impurity removal: the impurities in the sludge are separated by the vibrating grid of the impurity removal device; the impurities include plastic bags, branches, stones or other large particles, and the impurities are crushed and then enter the anaerobic cracking and carbonization device for treatment; the sludge passes through the pipe transported to the dehydration unit;

[0052] The 3rd step, sludge dehydration: the sludge water content after dehydration is less than 70%;

[0053]The fourth step is anaerobic pyrolysis to make carbon mud: the product obtained i...

Abstract

The invention discloses a system and a process for producing carbon mud by anaerobic cracking of sludge. The system comprises a sludge sucking device, an impurity removing device, a dehydration device, a material conveying device, an anaerobic cracking carbonizing device, a water feeding device and a water discharging device. The anaerobic cracking carbonizing device comprises a converter body, a sludge feeder, a mixed gas processing device, a tail gas treatment device, a biomass particle combustion device and a carbon mud cooling device; the sludge feeder comprises a feed hopper and a screw conveyor mechanism. The impurity removing device comprises a vibrating grid; impurity is recovered and conveyed to the sludge feeder, and sludge is conveyed to the dehydration device through a pipeline. The dehydration device comprises a sludge pelletizer or filter press. The system and the process have the advantage of reasonable design, realize harmless treatment, reduction and recycling of sludge, and further realize technical effects that stacking sludge on floor is avoided, garbage moving is omitted, large space occupation for sludge conveying is avoided, and product recycling is achieved in sludge disposal.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a system for producing carbon mud by anaerobic cracking of sludge. Background technique [0002] In the prior art, silt needs to be processed in three steps, silt cleaning, silt disposal, and silt absorption; in the process of silt cleaning, it has a greater impact on the aquatic environment and organisms, and it is prone to over-excavation or under-excavation. The dams cause harm; in the process of sludge disposal, the existing technology needs to be dehydrated and solidified, and then the storage yard is selected for pressure filtration. During the process of sludge solidification, more harmful gases and filtrates are produced, and the smell is overwhelming, which has a great impact on the surrounding environment and is easy to Produce secondary pollution and heavy metal pollution; silt disposal, the silt of the prior art is generally piled nearby after disposal, and i...
