Problems solved by technology
However, separate incineration of sludge also has the following disadvantages: large investment, high operating costs, a large amount of energy is consumed in the incineration process, and the cost of adding additional fuel is as high as 300-400 yuan / ton; when the sludge particles are uneven, it is easy to cause insufficient incineration and affect utilization; Incomplete sludge drying will lead to high moisture content of sludge in subsequent processes
The traditional sludge drying step is to first remove most of the water in the sludge through a filter press, and then dry the sludge by air-drying. The air-drying method has low efficiency and poor effect, and the moisture content of the sludge after air-drying Still around 15% (mass percentage) or even higher

Embodiment Construction
[0037] The present invention will be further described in detail through the accompanying drawings and specific embodiments below.
[0038] Such as figure 1 As shown, the present invention of the present invention also provides a kind of sludge treatment system, comprises horizontal filter press 1, sludge buffer room, sludge hoist 3, sludge drying device 4, anoxic pyrolysis furnace 5 and sludge Mud incinerator6.
[0039] The horizontal filter press 1 performs solid-liquid separation on the sludge, and the solid-liquid separated solid sludge enters the sludge buffer chamber 2, and the solid-liquid separated liquid enters the sewage recovery and treatment system. The sludge in the sludge buffer chamber is transported to the sludge drying device 4 by the sludge elevator 3 for drying, and the dried sludge enters the anoxic pyrolysis furnace 5, and the anoxic pyrolysis furnace 5 is used for drying The final sludge is pyrolyzed to form fuel and carbonized sludge particles, and the f...

The invention discloses a sludge drying device, which includes a screw feeder and a rotary furnace; and discloses a sludge treatment system, which includes a horizontal filter press, the aforementioned sludge drying device, anoxic pyrolysis Furnaces and sludge incinerators. By adopting the above technical scheme, the sludge can be fully dried after solid-liquid separation, and the water content in the sludge can be reduced. The rotary kiln has the characteristics of high efficiency and large batch size. Air drying can significantly improve work efficiency.
Description
technical field [0001] The invention relates to a sludge treatment system and a sludge drying device, belonging to the technical field of sludge treatment. Background technique [0002] At present, the sludge treatment methods in my country mainly include landfill, deep sludge dehydration, thermal drying, separate sludge incineration, sludge collaborative incineration, aerobic composting / fermentation, anaerobic digestion, etc. [0003] The treatment method of sludge landfill has small investment, large capacity and quick effect, but the sludge contains some toxic heavy metals, and because of the rich content of organic matter, the stability is very poor, and the organic matter will rot and deteriorate and release a large amount of odor and leachate. The gas produced by the landfill is mainly methane, which can cause explosion and combustion if proper measures are not taken. There is a problem of leachate that is difficult to deal with, and if it is not operated properly, it...
