Problems solved by technology

At present, the common problem of this type of system is that the bacteria and microorganisms in the water storage tank exceed the standard, which seriously affects the water quality and even smells bad.
So far there is no good solution
[0007] At the same time, the applicant found that the existing water purifiers are inconvenient to carry, so that when people need emergency water purification outdoors, there is no existing equipment

Embodiment 1

[0058] For the outdoor emergency water purification device of this embodiment, see figure 1 , including at least one pair of cathode electrodes 22 and anode electrodes 23, an electrolysis power supply 3 and a water container 1 for supplying power to the cathode and anode electrodes, and a water-permeable diaphragm 21 is arranged between the pair of cathode electrodes 22 and anode electrodes 23.

[0059] The water container 1 has a retractable folded side wall. The side wall of the water container 1 can be folded and shrunk, and can also be stretched and shrunk. The top of the water container 1 is provided with a window, and the water-permeable diaphragm 21 is fully covered on the window. In use, the negative electrode 22 is in contact with the water stored in the water container 1 , and the anode electrode 23 is in contact with the permeated water in the water container 1 through the water-permeable membrane 21 .

[0060] The water-permeable diaphragm 21 of this embodiment i...

Embodiment 2

[0082] The outdoor emergency water purification device of this embodiment is an improvement on the basis of Embodiment 1, and the difference from Embodiment 1 is:

[0083] In this embodiment, the water container 1 is manually filled with tap water. Still taking the city supply tap water in Dalian, China as an example, the electrolysis power supply 3 adopts an alternating pulse power supply whose forward voltage level is greater than the reverse voltage level, and the average voltage is 15V, the water-permeable diaphragm 21 adopts a microfiltration membrane, and the distance δ between the microfiltration membrane and the anode electrode 23 located outside the membrane is 15 mm.

Embodiment 3

[0085] The outdoor emergency water purification device of this embodiment is an improvement on the basis of Embodiment 1. The difference from Embodiment 1 is that in this embodiment, there are several through holes on the positive electrode 23 located outside the water-permeable diaphragm 21. The water-permeable membrane 21 is a nanofiltration membrane.

[0086] In this embodiment, the municipal tap water in Dalian, China is still taken as an example, and the distance δ between the water-permeable diaphragm 21 and the anode electrode 23 located outside the diaphragm is 0 mm and 10 mm, respectively.

[0087] The outdoor emergency water purification device of the present invention is not limited to the specific technical solutions described in the above embodiments, for example: 1) The electrolysis power supply 3 is a DC pulse power supply with a high level and narrow pulse width or a forward voltage level greater than a reverse voltage power supply; 2) The water container 1 is ...

Abstract

The invention relates to an outdoor emergency water purifier, belonging to the technical field of domestic drinking water quality advanced treatment. The outdoor emergency water purifier comprises at least one pair of negative and positive electrodes, an electrolysis power source for supplying power to the negative and positive electrodes, and a water container, wherein a water-permeable diaphragm is arranged between the negative electrode and positive electrode in pair; the water container is provided with telescopic folded side walls; the top of the water container is provided with a window; the water-permeable diaphragm is completely covered on the window; the negative electrode is arranged on the bottom in the water container; and the positive electrode is arranged outside the window on the top of the water container. When in use, the negative electrode contacts water stored in the water container, and the positive electrode only contacts the water container through the permeated water of the water-permeable diaphragm. The emergency water purifier is convenient to carry.

Description

technical field [0001] The invention relates to an outdoor emergency water purification device, which belongs to the technical field of advanced treatment of drinking water quality. Background technique [0002] Water pollution is mainly caused by pollutants produced by human activities, including industrial pollution sources, agricultural pollution sources and domestic pollution sources. Increasing water pollution has posed a major threat to human survival and has become a major obstacle to human health, economic and social sustainable development. According to the investigation of the authoritative organization in the world, at least 20 million people in the world die every year due to drinking unsanitary water. Therefore, water pollution is called "the number one killer in the world". At present, the deterioration of the water environment has seriously endangered the continuation of life, especially when natural disasters and man-made disasters suddenly occur. In some e...
