Problems solved by technology
The existing sloping plate settlement technology has relatively large resistance during the settlement process, and sludge is easy to remain on the sloping plate, thereby parasitizing microorganisms and causing blockage, so regular cleaning is required, and the maintenance cost is high
On the other hand, there is no heat collection and reuse device during the sludge settlement process, resulting in energy loss

The invention discloses an inclined pipe heat recovery sedimentation tank which comprises a sludge inlet pipeline, an inclined pipe coil inlet pipeline, an inclined pipe coil, an inclined pipe coil outlet pipeline, a supernatant recovery pipeline, a sludge sedimentation tank, a sludge absorption port, a sludge outlet pipeline and a sedimentation tank body; the sludge sedimentation tank is arrangedon the front side of the bottom of the sedimentation tank body, the sludge inlet pipeline is positioned above the rear side of the sedimentation tank body, the inclined pipe coil inlet pipeline and the inclined pipe coil outlet pipeline respectively enter the sedimentation tank body from the outside of the side of the sedimentation tank body, and the inclined pipe coil is suspended in the sedimentation tank body. The supernatant recovery pipeline is positioned outside the front side of the sedimentation tank body and is communicated with the interior of the sedimentation tank body; and the sludge absorption port is positioned in the sludge sedimentation tank, and the sludge outlet pipeline is connected with the sludge absorption port. The inclined tube type sedimentation technology is adopted, cleaning is not needed, the sedimentation area is increased, the efficiency is high, heat recovery is conducted, and energy is saved.
Description
technical field [0001] The invention relates to the field of sludge settlement, and in particular provides an inclined tube heat recovery settling tank. Background technique [0002] In the sludge sedimentation and separation industry, inclined plate settling tanks are usually used to achieve sludge-water separation. The existing sloping plate settlement technology has relatively large resistance during the settlement process, and sludge is easy to remain on the sloping plate, thereby parasitizing microorganisms and causing blockage, so it needs to be cleaned regularly, and the maintenance cost is high. On the other hand, there is no heat collection and reuse device during the sludge settling process, resulting in energy loss. Contents of the invention [0003] The purpose of the present invention is to provide an inclined tube heat recovery settling tank, adopting the inclined tube type settling technology, without cleaning, increasing the settling area, high efficiency,...
