Problems solved by technology

With this improved structure, the flushing water has been applied to achieve the purpose of saving water, but the flushing effect of the ultrafiltration membrane is still not ideal
[0003] Technical personnel in the industry know that the effect of forward flushing is obviously not as good as that of backwashing, but to achieve backwashing, reverse pressure is required. Usually, the pipeline system is more complicated to implement, and some additional mechanisms are required to provide reverse pressure for the ultrafiltration membrane. The piping system is complex and the manufacturing cost is high

Embodiment 1

[0062] Such as figure 1 Shown, be the flowchart of a kind of ultrafiltration membrane flushing method provided by the present invention, this method comprises the following steps:

[0063] Step a: closing the flushing port of the ultrafiltration processor or the flushing pipeline connected with the flushing port and the water outlet of the gas storage or the water outlet pipeline connected with the water outlet.

[0064] Step b: connect the pressure water source at the inlet of the ultrafiltration processor, make the water with pressure flow through the ultrafiltration processor and then flow into the gas storage, and compress the gas inside the gas storage.

[0065] Step c: Open the flushing port or the flushing pipeline of the ultrafiltration processor, expand the gas and press water into the ultrafiltration processor from the outlet of the ultrafiltration processor, The flush port of the device is discharged.

Embodiment 2

[0067] Such as figure 2 Shown, is the flow chart of another kind of ultrafiltration membrane flushing method provided by the present invention, and this method comprises the following steps:

[0068] Step a: closing the flushing port of the ultrafiltration processor or the flushing pipeline connected with the flushing port and the water outlet of the gas storage or the water outlet pipeline connected with the water outlet.

[0069] Step b: connect the pressure water source at the inlet of the ultrafiltration processor, make the water with pressure flow through the ultrafiltration processor and then flow into the gas storage, and compress the gas inside the gas storage.

[0070] Step c: Open the flushing port or the flushing pipeline of the ultrafiltration processor, expand the gas and press water into the ultrafiltration processor from the outlet of the ultrafiltration processor, The flush port of the device is discharged.

[0071] Step d: Repeat step a, step b and step c i...

Embodiment 3

[0073] Such as image 3 As shown, it is a flow chart of another ultrafiltration membrane flushing method provided by the present invention. When the water outlet of the gas storage or its outlet pipeline is kept closed and the pressure water source of the ultrafiltration processor is kept connected, the ultrafiltration The membrane flushing method includes the following steps:

[0074] Step a1: close the flushing port of the ultrafiltration processor or the flushing pipeline connected with the flushing port, so that the water with pressure flows through the ultrafiltration processor and then flows into the gas storage, compressing the gas inside the gas storage gas.

[0075] Step b1: Open the flushing port or the flushing pipeline of the ultrafiltration processor, expand the gas and press water into the ultrafiltration processor from the outlet of the ultrafiltration processor, Rinse port to discharge.

Abstract

The invention provides an ultrafiltration membrane washing method, an ultrafiltration membrane washing device and a water purifier provided with the ultrafiltration membrane washing device. The ultrafiltration membrane washing device comprises an ultrafiltration processor, wherein the ultrafiltration processor is provided with an inlet, an outlet and a washing port, the inlet is used for being communicated with a pressure water source, the washing port is used for discharging washing water, a hollow fiber ultrafiltration membrane assembly is arranged in the ultrafiltration processor, the ultrafiltration membrane washing device further comprises a gas storage device, the outlet is communicated with the inside of the gas storage device, and the washing port is communicated with a first washing valve through a washing pipeline; a gas storage area and a liquid storage area are arranged in the gas storage device, and gas is stored in the gas storage area. Compared with the prior art, the ultrafiltration membrane washing device adopting the technical scheme can wash an ultrafiltration membrane through pressure provided by a water source, the washing effect is improved, the service life of the ultrafiltration membrane can be prolonged remarkably, and water treatment materials are saved. The ultrafiltration membrane washing device is simple in system, low in cost and easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to an ultrafiltration membrane washing method, a device and a water purifier with the device. Background technique [0002] The ultrafiltration membrane used in water purifiers is currently a popular design method using the dead-end filtration method. Although the pipeline system is simple in this design, the ultrafiltration membrane is easy to clog. The filter membrane, that is, the ultrafiltration membrane has become a disposable water treatment material, which is a great waste. Another design is to use cross-flow filtration or cross-flow filtration, that is, flushing water is drained while filtering. This design is not easy to clog the ultrafiltration membrane, which can significantly prolong the service life of the ultrafiltration membrane, but the waste of water resources is also very large. considerable. The improved method is that the design structure still adopt...
