A portable lightweight personal water purification device

Abstract

The invention belongs to the technical field of drinking water treatment devices and discloses a portable lightweight personal water purification device. The device includes a ternary gradient tubular membrane pretreatment system, a desalination system and a power supply system; the ternary gradient tubular membrane pretreatment system includes a ternary gradient tubular ultrafiltration membrane, and the ternary gradient tubular ultrafiltration The membrane is composed of a support layer, a transition layer and a separation layer from outside to inside. The support layer and transition layer are PVDF sintered layers, and the separation layer is a functionalized Al2O3 / PVDF membrane material; the desalination system includes carbon fiber tube desalination desalination membrane . The invention adopts a high-strength inorganic / organic composite tubular membrane with a ternary gradient structure, which has large flow rate, good self-cleaning property, strong sewage discharge ability, and high mechanical strength; the weight of the carbon fiber membrane tube is only 10% of the traditional glass fiber reinforced plastic membrane tube, The weight of the equipment is greatly reduced; the whole device is small in size and can be loaded in a suitcase, which is convenient to carry and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of drinking water treatment devices, and in particular relates to a portable lightweight personal water purification device. Background technique [0002] Our country is a country with frequent natural disasters. In the post-disaster reconstruction work, how to make the victims and relief troops drink clean drinking water is very important. Material transportation is time-consuming and labor-intensive, adapting measures to local conditions, using local materials, using local water resources, treating different water qualities according to needs, and efficient water purification is a major bottleneck; because people who work in the field or those who love freedom, adventure and love nature , When camping in the wild, safe and clean drinking water is essential. Constrained by the current environmental conditions in our country, untreated natural water is difficult to ensure safety and pollution-free. Existing...

Problems solved by technology

[0003] At present, the patent of personal seawater desalination system has not been reported yet. The existing seawater desalination system has a large volume, which is suitable for industrial production and cannot be easily carried.

However, the existing personal water purification system is difficult to achieve fast and efficient desalination, does not have the ability to desalinate seawater, and the membrane components used for filtration are easily polluted, and cannot be cleaned automatically, which shortens the service life of the membrane
