Problems solved by technology
However, the sewage treatment plant has a large amount of sludge, high moisture content, complex composition and perishable, high energy consumption and large investment in the sludge treatment process, resulting in a large amount of untreated sludge being randomly stacked or simply landfilled, and due to the sludge Contains a large amount of combustible organic matter. If it is directly landfilled, it will not only pollute the environment, but also waste useful resources in the sludge

Embodiment Construction
[0018] Below, the technical solution of the present invention will be described in detail through specific examples.
[0019] Such as figure 1 as shown, figure 1 It is a schematic structural diagram of a sludge treatment equipment proposed by the present invention.
[0020] refer to figure 1 , a kind of sludge treatment equipment proposed by the embodiment of the present invention, comprising: a furnace body 1, a dehydration device 2 and a drying device 3, wherein:
[0021] The furnace body 1 includes an inner furnace body 1 and an outer furnace body 12 located outside the inner furnace body 11. A gap is reserved between the outer peripheral surface of the inner furnace body 11 and the inner peripheral surface of the outer furnace body 12 to form a thermal insulation chamber for heat preservation. The chamber is provided with a smoke exhaust port, and the heat preservation chamber is provided with a coil pipe 4 spirally arranged around the outer peripheral surface of the in...

The invention discloses sludge treatment equipment. The sludge treatment equipment comprises a furnace body, a dehydrating device and a drying device, wherein the dehydrating device is used for conveying sludge into the drying device; in addition, the inner diameter of a cylinder body in the dehydrating device, and the rotation diameters and the screw pitch of screw blades are gradually reduced, so that water in the sludge is separated step by step; the drying device is used for conveying the dehydrated sludge into the furnace body; a conveying path of the drying device is arranged in the furnace body, and the dehydrated sludge is dried by using high temperature in the furnace body, so that the sludge is easy to ignite; when the dried sludge enters the furnace body, the sludge is ignited by materials in the furnace body to serve as fuel for supplying heat to the furnace body, so that the aim of self-supply of fuel is achieved by a mode that equipment only needs to feed certain fuel at the beginning, and subsequently the sludge is discharged. According to the sludge treatment equipment disclosed by the invention, the problem of environmental pollution can be effectively avoided, and the sludge serving as energy is recycled, so economy and environmental protection are realized.
Description
technical field [0001] The invention relates to the technical field of sludge treatment, in particular to sludge treatment equipment. Background technique [0002] At present, more than 90% of urban sewage treatment plants in the world use activated sludge method or biofilm method, and a large amount of excess sludge is generated during the treatment process. The usual practice of treating sludge in existing sewage treatment plants is to concentrate, dehydrate and stabilize it before using it for reclamation or land use. However, the sewage treatment plant has a large amount of sludge, high moisture content, complex composition and perishable, high energy consumption and large investment in the sludge treatment process, resulting in a large amount of untreated sludge being randomly stacked or simply landfilled, and due to the sludge It contains a large amount of combustible organic matter. If it is directly landfilled, it will not only pollute the environment, but also wast...
