Technical Field

[0002] A multi-media filter is a water treatment device that uses a combination of various filter media with different particle sizes and properties (such as quartz sand, anthracite, activated carbon, magnetite, etc.). Through physical interception, adsorption and chemical reaction, it removes impurities such as suspended solids, colloids, organic matter, iron and manganese ions from the raw water, thereby achieving the purpose of purifying the water quality.

There is no cross-flow vortex filtration method, the filtration method is simple, the filter media has a short fouling cycle and is prone to caking, the backwashing frequency is high, the backwashing water volume is large, and the filter media needs to be replaced regularly, resulting in high operating energy consumption.

[0020] This utility model provides a dual-tower cyclone nano-silicon filter device, including a horizontal double-layer tower body, a cyclone water distribution unit, a nano-silicon fine filter medium, and a pulse air-water backwashing device;

[0021] The vortex water distribution unit is located at the inlet end of the horizontal double-layer tower body, the nano-silicon fine filter medium is located at the lower end of the vortex water distribution unit, and the pulse air-water backwashing device is located on the horizontal double-layer tower body.

[0022] In this embodiment, the traditional vertical filter is replaced with a horizontal structure, and it is designed as a double-layer structure that can be used in series or in parallel. After the change to a horizontal structure, the equipment height is reduced by 40%, the equipment floor space is reduced by 80%, and the filter media height is reduced by 50%. This allows for a higher filtration flow rate (40-50 m / h), a lower backwash intensity, and an 80% reduction in backwash water volume. Furthermore, the traditional multi-media filter media (quartz sand, anthracite filter media, etc.) are replaced with nano-silicon fine filter media, which has higher filtration accuracy, is less prone to caking, has less filter media loss during operation, a longer backwash cycle, and does not require filter media replacement, only periodic replenishment.

[0023] Furthermore, the horizontal double-layer tower body includes two filter tower structures 1, connecting pipes 2, and exhaust valves 3. The connecting pipes 2 are fixedly connected to the corresponding filter tower structures 1, and the exhaust valves 3 are located at the upper end of the connecting pipes 2. The two filter tower structures 1 can be connected in series or in parallel. The vortex water distribution unit includes a tangential inlet 4 and an angle-adjustable guide vane 5. The tangential inlet 4 is located on the side of the corresponding filter tower structure 1, and the angle-adjustable guide vane 5 is located on the tangential inlet 4. The nano-silicon fine filtration filter medium includes an active nano-silicon filter layer 6, which is located below the vortex water distribution unit, and the particle size of the active nano-silicon filter layer 6 gradually increases. The pulse air-water backwashing device includes a backwash air pipe 7 and a backwash water pipe 8, which are respectively located on the corresponding filter tower structures 1.

[0024] In this embodiment, water is pumped into the inlet of the filter tower structure 1 and enters the vortex water distribution unit of the double-layer tower body. The vortex water distribution unit causes the incoming water to flow in both horizontal and vertical directions, creating different distribution directions. The water flows from top to bottom through the active nano-silicon filter media layer 6. After filtration through the filter media layer, the produced water is discharged through the product water outlet. After the filter device has been running for a period of time, backwashing is required. Backwashing is performed using a gas-water backwashing system that uses clean water and compressed air to backwash the filter device. The backwash water is discharged through the drain outlet. The minimum processing capacity of a single unit is 100t / h, and the maximum processing capacity is 600t / h. The equipment is a skid-mounted complete unit, including the equipment body and an automatic control system. In addition, the tilt angle of the guide vanes is adjustable from 25° to 45°.
