Sludge sedimentation tank --lamella clarifier
Application areas of the Lanmera precipitator
Lamella clarifier also called inclined plate sediment tank, is used to separate sedimentable solid (sedimentable particles) from liquids.
It is kind of high efficient combined type settling tank; set many dense inclined tube packing in sediment area, to make the suspended impurity in water sediment.
Such tank can improve sediment efficiency 50~60%, it can improve treatment capacity 3~5 times in the same area. It can design different flow rate inclined plate sediment device according to raw wastewater test report, it need dose flocculant usually.
It mainly used in sludge sediment process, such as river water cleaning, Printing and dyeing wastewater, Papermaking wastewater, Mining sand sedimentation, Plastic waste cleaning sludge sedimentation etc. This machine suit for almost of the sludge sediment in sewage treatment.
Introduction
The lamella clarifier also called inclined plate sediment tank. It is kind of high efficient combined type settling tank; set many dense inclined tube packing in sediment area, to make the suspended impurity in water sediment, water rise flow along inclined tube, the separated sludge down to the tank bottom along the inclined tube by gravity, then discharge it in concentration. Such tank can improve sediment efficiency 50~60%, it can improve treatment capacity 3~5 times in the same area. It can design different flow rate inclined plate sediment device according to raw waste water test report, it need dose flocculant usually.
Inclined plate sediment tank have 60° dip angle to ground. When water rise flow along the inclined tube ,the sludge and suspended solids can settle onto the sinclined tube, then slide back to sludge layer rely on gravity, then settling in sludge collecting hopper, and flow into sludge tank by sludge pipe for separate treatment or comprehensive utilization. The supernatant fluid gradually rise to
Feature
1),Simple structure,without wearing parts,wear well,decrease maintenance
2),High-efficiency treatment of wastewater with high solid content (grit, clay, lime, metal particles)
3),Installed indoors and outdoors (but ambient temperature needs to be greater than 0°C)
4),The inclined plate sedimentation tank can create a good laminar flow environment for better sedimentation.
5),Intensive design minimizes hydraulic disturbances caused by wind or temperature changes.
6),Suitable for on-site unattended automatic continuous operation
7),Small occupy area,low investment,high efficient.Small power,save energy
8),Short retention time,high sediment efficiency,no sludge back flow.
Structure introduction
1),Inclined tube material : PVC,PE,PP ,inclined plate: carbon steel lining
2),Inclined tube cross section is regular hexagon, inclined plate cross section can be parallel-plate.
3),The cleaning water area height is 1.0-1.5m above the inclined pipe top, the water distribution zone below the bottom no less than 1.0-1.5m, mechanical discharge sludge, the water distribution zone height should more than 1.6m, convenient install and maintenance.
4),The Re number in water flow less than 500,Fr number is 10-3-10-5 in inclined pipe.
5),Inclined tube design flow rate is 1.0-4.0mm/s, inclined plate 10-20mm/s.
