Description

Water inlet grid for membrane element

Technical Field

The utility model belongs to the technical field of the water treatment, especially, relate to a net of intaking for film element.

Background

Along with the development of society, the pollution of water source, water resource are more and more nervous, utilize the reverse osmosis, the pollutant (such as harmful substance such as mud, heavy metal, bacterium, virus) in the effective removal aquatic of water purifier of receive filter membrane component makes us can drink clean water, and because its small in size, convenient to operate's reason such as more and more families, hotel, school begin to use the water purifier. The reverse osmosis membrane and the nanofiltration membrane element are core components in the water purifier, the water production effect of the water purifier is directly related to the water production efficiency of the reverse osmosis membrane element, and the reverse osmosis membrane and the nanofiltration membrane element are used as consumable materials in the water purifier in a highly periodic replacement mode, so that the demand of the reverse osmosis membrane and the nanofiltration membrane element is increased day by day, and the market of owners is huge.

The water inlet grid is used in a membrane element, and mainly aims to prevent two membranes from being attached together to block the flow of water and provide a channel for raw water to enter the membrane. However, the weft and warp of the existing water inlet grid are common silk threads with the same thickness, so that under the condition of poor raw water quality condition (higher TDS value, higher hardness, higher slurry content and the like), pollutants and scales are easy to attach to the surfaces of the membrane and the grid, thereby causing the blockage of the membrane element and reducing the filtering effect and the water production efficiency.

Therefore, it is necessary to invent a water inlet grid for membrane elements.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a net of intaking for film element to the weft and the warp of solving current net of intaking are the silk thread that ordinary thickness is unanimous, and this has just led to, and under the not good (TDS value is higher, hardness is higher, mud content is higher etc.) condition of raw water quality of water, pollutant, scale deposit are attached to diaphragm and net surface easily, thereby cause the film element to block up, reduce the problem of filter effect and product water efficiency. A water inlet grid for a membrane element comprises an RO membrane, wherein the RO membrane is formed by weaving weft yarns and warp yarns; the grid formed by interweaving the weft and the warp is rhombus-shaped; and a plurality of round holes are formed in the weft and the warp.

Weft and warp are the PP material to set up to hollow formula cylindric, made things convenient for the effect of passing through of raw water, improved product water efficiency.

The diameter of weft and warp is arbitrary numerical value, can customize according to the purifier of equidimension not or customer's demand, and application scope is wide.

The round hole sets up to the penetrability hole to the axis direction is seted up around weft and warp, can effectually prevent the pollutant scale deposit, prevents that the filth from attaching to on diaphragm and net, reduces dirty stifled possibility, prolongs the life of reverse osmosis, nanofiltration membrane element, has improved the efficiency of system water, the energy can be saved.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses the setting of RO membrane, RO membrane are woven by weft and warp and are formed, and weft and warp are the PP material to set up to hollow formula cylindric, made things convenient for the effect of passing through of raw water, improved product water efficiency.

2. The utility model discloses warp and weft's setting, weft and warp's diameter are arbitrary numerical value, can customize according to not purifier of equidimension or customer's demand, and application scope is wide.

3. The utility model discloses the setting of round hole can effectually prevent the pollutant scale deposit, prevents that the filth from adhering to on diaphragm and net, reduces dirty stifled possibility, prolongs reverse osmosis, nanofiltration membrane element's life, has improved the efficiency of system water, the energy can be saved.
