A fuel self-contained sludge treatment device

Abstract

The invention discloses a self-fuel-feeding type sludge treatment device which comprises a furnace body, a first driving mechanism, a second driving mechanism and a third driving mechanism. The furnace body is provided with a furnace chamber, and a first guiding barrel, a crushing barrel and a second guiding barrel are arranged in the furnace chamber. A first feeding screw is arranged in the first guiding barrel and internally provided with an exhaust channel. The first driving mechanism is used for driving the first feeding screw to act. A feed inlet of the crushing barrel communicates with a discharge outlet of the first guiding barrel, and a discharge outlet of the crushing barrel is located in the furnace chamber. A crushing mechanism is arranged in the crushing barrel. The second driving mechanism is used for driving the crushing mechanism to conduct crushing. A feed inlet of the second guiding barrel communicates with the discharge outlet of the crushing barrel, and a discharge outlet of the second guiding barrel communicates with the furnace chamber. A second feeding screw is arranged in the second guiding barrel. The third driving mechanism is used for driving the second feeding screw to act. The self-fuel-feeding type sludge treatment device can effectively avoid environment pollution, sludge can be recycled to serve as fuel, and high economy efficiency and environment protection are achieved.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a fuel self-contained sludge treatment device. 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 environ...

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
