Embodiment 1

[0066] Example 1: Six-stage media filtration

[0067] In this embodiment, the structure of the filter assembly of the water purifier can refer to Figure 7 Part of the structure is shown in , including six-stage filter media. The filter assembly includes stainless steel mesh (on which coarse filter material is placed), microfiltration membrane, glass fiber (separation material), ultrafiltration membrane, and adsorption material, which are arranged in sequence from top to bottom. And high-pressure filter membrane (reverse osmosis membrane). Specifically, the volume of the first housing is about 100mL, and the area of ​​the pressure plate in the drive assembly is 0.002m 2 Left and right, the length of the screw is about 5cm, and the diameter of the screw is about 3.2cm 2 , The thread pitch is 3mm. Rotate the knob to move the pressure plate of the drive assembly up to close to the top of the first housing, turn the first housing upside down (that is, the top of the first housi...

Embodiment 2

[0068] Embodiment 2: single membrane filtration

[0069] In this embodiment, other water purifier structures and water purification methods are the same as in Embodiment 1, except that the filter assembly of the water purifier directly adopts a combination of stainless steel mesh coupled with reverse osmosis membrane / nanofiltration membrane.

Embodiment 3

[0070] Embodiment 3: double-membrane filtration

[0071] In this embodiment, other water purifier structures and water purification methods are the same as in Embodiment 1, except that the filter components of the water purifier are stainless steel mesh coupled microfiltration membranes / ultrafiltration membranes and reverse osmosis membranes.

Abstract

The invention discloses a portable emergency water purifier. Particularly, the water purifier comprises a first shell, wherein a through hole is formed in the top of the first shell; a driving component arranged in the first shell, wherein the driving component comprises a screw rod, the screw rod passes through the through hole and extends outside the first shell, one end of the screw rod, extending into the inner part of the first shell, is provided with a pressing plate, the other end of the screw rod is provided with a knob, the knob is configured to drive the screw to rotate and push thepressing plate to move up and down in the first shell; and a filter component arranged at the bottom of the first shell, wherein the pressing plate and the filter component define a water inlet spacein the first shell. Therefore, the water purifier does not need an external power supply when in use, is convenient to carry, and is coupled with a pressurizing system, a filtering system and a disinfection system, and general sewage, river water, lake water and seawater can be used as water sources and can be purified to drinking water, the device can be used as an outdoor portable emergency water purification device.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a portable emergency water purifier, and more specifically to the water purifier and a water purification method. Background technique [0002] Water is the origin of life, and human beings cannot live without water. However, in today's world, human beings are facing serious problems of water resource shortage and water pollution. As a common sewage treatment technology, membrane separation technology has the advantages of simple process and convenient operation. Membrane separation technology refers to the technology that achieves selective separation of a mixture of molecules with different particle sizes at the molecular level when they pass through a membrane. Membrane is a material with selective separation function. The selective separation of membrane can realize the separation, purification and concentration of different components of feed liquid. It is different from ...
