Double-layer rotational-flow-water-distribution activated carbon filter

Abstract

The invention relates to a double-layer rotational-flow-water-distribution activated carbon filter. The double-layer rotational-flow-water-distribution activated carbon filter comprises a tank. An exhaust pipeline is arranged at the top of the tank. A water inlet pipeline is arranged on one side of the exhaust pipeline. A first three-way connector is arranged at the tail end of the water inlet pipeline. One end of the first three-way connector is connected with the water inlet pipeline. The other two ends of the first three-way connector are respectively a water inlet and a backwashing water outlet. A double-layer rotational-flow water distribution device is arranged below the end, extending into the tank, of the water inlet pipeline. The double-layer rotational-flow water distribution device comprises an upper-layer water discharge retaining plate directly facing the end of the water inlet pipeline and a lower-layer water discharge rotational-flow plate arranged below the upper-layer water discharge retaining plate, wherein the upper layer water discharge retaining plate comprises a support connected with the top end of the tank and a water distribution plate at the bottom end of the support, conical through holes are evenly formed in the water distribution plate, the distance between the lower-layer water discharge rotation flow plate and the upper-layer water discharge retaining plate is 40-80mm, the lower-layer water discharge rotational flow plate comprises a plurality groups of fan-shaped plates, the fan-shaped plates are evenly distributed around a circle center, and each group of the fan-shaped plates is formed by a plurality of rotation flow plates.

Description

Technical field [0001] The invention relates to the field of environmentally friendly sewage, and in particular to a multi-media filter. Background technique [0002] Activated carbon filter is a kind of more commonly used water treatment equipment. As a pretreatment of water treatment desalination system, it can effectively ensure the service life of subsequent equipment, improve the quality of effluent water, and prevent pollution, especially to prevent reverse osmosis membranes, ion exchange resins, etc. Free residual oxygen poisoning pollution. [0003] Activated carbon filter purpose: mainly used to remove organic matter, smell, color, heavy metal ions, residual chlorine (CL2), etc. in water. As a pretreatment for reverse osmosis, electrodialysis, and ion exchangers. Activated carbon device can play a good protective role for these equipment. [0004] Existing activated carbon filters are all sprayed water, the water needs a certain pressure, the energy consumption is large, ...

AI Technical Summary

Problems solved by technology

[0004] The existing activated carbon filter water distribution is spray water distribution, the water needs a certain pressure, the energy consumption is large, and the spray pipe is easy to block, the service life is short, and needs further improvement
