Problems solved by technology
[0011] However, if this method still contains toxic substances such as heavy metal ions, final treatment must be done, solidified and buried deeply, and the engineering method is unstable. It needs external heat during treatment, and even if there is external heat, it is difficult to maintain and continuous operation management is not easy

specific Embodiment approach
[0033] A kind of sludge pyrolysis method, comprises the following steps:
[0034] (1) Mix the sludge with the cellulose lignin activator;
[0035] (2), drying the above mixture at low temperature;
[0036] (3) Extruding and granulating the dried mixture;
[0037] (4) Drying the product extruded and granulated through the above steps at low temperature until the water content of the mud is less than 10%;
[0038] (5) The above-mentioned dried mud blocks are passed through a low-temperature continuous carbonization furnace and a separation device to obtain the final product.
[0039] Such as figure 1 , 2 . As shown in 3, a sludge internal heat continuous retort furnace is characterized in that it includes a retort furnace main body 1, an insulating layer 10 is coated on the outside of the retort furnace main body, and a fire smoke pipe 8 passes through the retort furnace main body. It communicates with the outside, and there are two built-in gas pipes 5 inside the retort fu...

The invention discloses an internal-heat continuous dry distillation furnace for sludge. The internal-heat continuous dry distillation furnace comprises a dry distillation furnace main body; the outer side of the dry distillation furnace main body is coated by a heat-insulation layer; the interior of the dry distillation furnace main body is communicated with the exterior through a fire smoke pipe and is provided with two in-built combustion gas pipes; the dry distillation furnace main body is further provided with a raw material conveying system; a raw material is conveyed into the combustion gas pipes through the raw material conveying system; the tail ends of the combustion gas pipes are connected with a discharging system; and the discharging system is connected with a discharging trolley. A product of the internal-heat continuous dry distillation furnace has the advantages of no odor, no secondary pollution substances like flue gas and environment friendliness; the internal-heat continuous dry distillation furnace realizes circular economy, converts sludge garbage into reusable resources, obtains useful new substances and realizes energy conservation, low consumption and environmental protection.
Description
technical field [0001] The invention relates to a sludge pyrolysis method and a device suitable for the method. Background technique [0002] The sludge treatment method at this stage generally adopts sludge incineration, which is a process of sludge treatment. It uses an incinerator to heat and dry the dewatered sludge, and then uses high temperature to oxidize the organic matter in the sludge to make the sludge a small amount of ash. [0003] A reduction, stabilization and harmless treatment method for sludge post-treatment. This method can completely remove water and organic matter in sludge and kill pathogens. There are two methods of sludge incineration: complete combustion and incomplete combustion. [0004] It can remove all the moisture and organic matter in the sludge, kill all pathogens, and minimize the volume of sludge. [0005] There are many types of sludge incinerators, such as vertical multi-stage incinerators, rotary drum incinerators, fluidized incinera...
