Diagonal pipes are mainly used for various sedimentation and sand removal purposes. It has been widely used in water supply and drainage engineering in the past decade and has become a water treatment device. It has the advantages of wide applicability, high processing efficiency, and small footprint. Suitable for water inlet sand removal, general industrial and domestic water sedimentation, sewage sedimentation, oil separation, and tail tension concentration treatment. It is suitable for both new construction projects and the renovation of existing old tanks, and can achieve good economic benefits.
Characteristics of inclined pipes:
1. The wet area is large and the hydraulic radius is small.
2. The laminar flow state is good, and particle settling is not affected by floc flow interference.
When the length of the inclined pipe is 1 meter, the effective load is designed at 3-5 tons per square meter per hour. V0 is controlled within the range of 2.5-3.0 millimeters per second, resulting in excellent effluent quality.
4. When using honeycomb inclined pipes at the water intake with a length of 2.0-3.0 meters, they can safely operate and treat high turbidity with a mud and sand content of 50-100 kg/m3.
5. Adopting inclined tube sedimentation tank, its processing capacity is 3-5 times that of horizontal flow sedimentation tank, and 2-3 times that of accelerated clarification tank and pulse clarification tank.
