A brief introduction and functional explanation of honeycomb inclined pipes. Also known as inclined pipe filler, honeycomb filler, and polypropylene inclined pipe. Due to the fact that hexagonal is the most sturdy structure, diagonal pipes are made into hexagonal structures, resembling honeycomb, hence they are also called honeycomb diagonal pipes or hexagonal honeycomb diagonal pipes.

The inclined tube is mainly used for various sedimentation and sand removal functions. It is the most widely used and inclined pipe as a water treatment device in water supply and drainage engineering in the past decade. Widely used in water treatment sedimentation tanks and sedimentation equipment. It is currently the most widely used and mature water treatment equipment device in water supply and drainage engineering. It has the advantages of wide applicability, high treatment efficiency, and small footprint. Suitable for desanding general industrial and domestic water supply sedimentation, sewage sedimentation, oil separation, and tailings concentration treatment at the water inlet. It is suitable for both new construction projects and the renovation of existing old ponds, and can achieve good economic benefits.

The honeycomb inclined pipe quality honeycomb water industry has been dedicated to water treatment for several years, committed to providing high-quality services to users with reasonable design, high-quality products, and precise construction, and is a leader in the water treatment industry.

The materials used for producing honeycomb inclined pipes mainly include polypropylene, ethylene propylene copolymer, polyethylene, and fiberglass. The inclined tube adopts hot melt welding, and the welding tool is a specially designed electric soldering iron head, which is stronger than ordinary welding. Secondly, there are up to 20 inclined pipe welding points in the honeycomb, with an average of 5cm per point. Compared to the common 2-4 points in the market, the effective welding area is many times larger.

The honeycomb inclined pipe is welded on the fixture, and all workers have undergone strict training to ensure that the inclination angle of each inclined pipe is 60 °, which is more standard.

The product features of inclined pipes mainly include the following points:

1. Large wet circumference and small hydraulic radius.

2. The laminar flow state is good, and particle sedimentation is not affected by floc flow interference.

When the length of the inclined pipe is 1 meter, the effective load is designed as 3-5 tons/m2 · h. V0 is controlled within the range of 2.5-3.0 millimeters per second, resulting in the best effluent quality.

4. Honeycomb inclined pipes are used at the water intake, with a length of 2.0-3.0 meters, which can safely operate and handle high turbidity with a sediment content of 50-100 kg/m3.

5. Adopting a inclined tube sedimentation tank, its processing capacity is 3-5 times that of a horizontal flow sedimentation tank, and 2-3 times that of an accelerated sedimentation tank and a pulse sedimentation tank.

Installation Procedure 1: Bottom Discharge Pipe Installation of Sedimentation Tank: The installation sequence of the inclined tube sedimentation tank generally starts from the bottom, and the installation of the bottom discharge pipe system is completed first to ensure that the opening of the discharge pipe meets the design requirements, is firmly fixed, and is checked to be correct before proceeding to the next installation process.

2. Complete the installation of the filler bracket: According to the construction drawing for the installation of the filler bracket in the inclined pipe sedimentation tank, first install the filler bracket in place, check that all welding nodes are secure, the bracket strength is sufficient to withstand the weight of the filler, and complete anti-corrosion treatment on the surface of the bracket; 3. Complete the ironing of inclined tube fillers: According to the ironing method of inclined tube fillers, each inclined tube filler is packaged as a separate ironing unit, with a unit area of 1m2 after ironing. After ironing, it is neatly stacked on the site (with a small amount of loose pieces reserved for backup).

4. Assembly inside the honeycomb inclined tube filler pool: Assemble the hot pressed filler unit from left to right on the upper part of the filler bracket. Always maintain a constant angle of 60 °, and each unit should be properly compressed during assembly. If the size is not exactly suitable when assembled to the far right, it is necessary to use loose diagonal tube fillers according to the size before assembly until all are in place.

5. Fixed upper part of honeycomb inclined pipe filler: Due to the specific gravity of the inclined pipe filler being 0.92, which is slightly less than water, after the inclined pipe filler is assembled in place in the tank, a 10mm round steel needs to be pulled from left to right above the filler for reinforcement (two round steel bars are required to pass through the upper part of each unit filler), and the two ends of the round steel are reliably fixed on the wall of the sedimentation tank, After installing the round steel, it can effectively prevent the possibility of loosening and floating of the inclined pipe filler during initial use. The round steel is anti-corrosion with epoxy coal tar asphalt.

6. Operation and commissioning of honeycomb inclined tube sedimentation tank: (1) Check whether the inlet water is uniform and not to cause any impact on the sedimentation tank, which may affect the sedimentation effect; (2) Adjust the height and levelness of the outlet weir groove to a suitable level to maintain uniform outlet water; (3) After the above construction procedures, the installation of the filling materials for the inclined tube sedimentation tank has been fully completed. After normal operation, it is necessary to determine the sludge discharge cycle based on the concentration of suspended solids in the influent, and pay attention to timely sludge discharge to ensure that the inclined tube sedimentation tank always maintains good operating conditions and satisfactory effluent quality.

The honeycomb inclined pipe has strong toughness, good assembly strength, no deformation, no embrittlement, long service life, and anti-aging. Over the years, it has been successfully used in water treatment projects of many paper mills, chemical plants, and power plants, and has been praised by users for its high quality and high cost performance.
