Embodiment

[0020] The auxiliary cleaning device of the water purifier of this embodiment can be found in figure 1 , including a water container 1 provided with a water inlet 5, the water inlet 5 of the water container 1 is externally connected to the sewage outlet 6 of the existing water purifier 7 (the water outlet or the water inlet of the existing water purifier 7 can also be externally connected). The shell of the water container 1 is used as the negative electrode 2, and the positive electrode 3 is arranged in it. Between the negative electrode 2 and the positive electrode 3, there is no gap between the water permeable porous membrane 4, and the area of ​​the opposite side of the water permeable porous membrane 4 and the negative electrode 2 or the positive electrode 3 is smaller than that of the negative electrode 2 or the positive electrode 3 and the water permeability. The area of ​​the opposite sides of the porous membrane 4 , the ratio of the minimum area of ​​the water-permeab...

Abstract

The invention relates to an auxiliary cleaning device of a water purifier, which belongs to the technical field of electrolysis equipment. The device comprises a water container with a water inlet, wherein the water inlet is externally provided with a drainage hole, a water outlet or water inlet of a conventional water purifier; the shell of the water container is used as a negative electrode; the shell is internally provided with a positive electrode; a water permeable porous film is sandwiched between the negative electrode and the positive electrode without seam; the area of a side surface of the water permeable porous film opposite to the negative electrode or the positive electrode is smaller than the area of a side surface of the negative electrode or the positive electrode opposite to the water permeable porous film. By adopting the device, hydrogen with a great deal of ultramicro bubble can be generated, then a flocculent precipitate function is achieved, pollutants in source water are removed, and meanwhile the source water is sterilized.

Description

technical field [0001] The invention relates to a device for cleaning water quality, which belongs to the technical field of electrolysis equipment. Background technique [0002] The production of hydrogen (and oxygen) by electrolysis of water has a wide range of applications. When a DC electrolysis voltage is applied between the two electrodes to electrolyze water, the process of hydrogen evolution at the cathode and oxygen evolution at the anode occurs. The method of producing hydrogen by electrolysis of water usually includes electrolysis without isolation membrane, electrolysis with isolation membrane, zero-spacing electrolysis, solid polymer electrolyte electrolysis of water to produce hydrogen (oxygen) and other methods. At present, 1m is produced by electrolysis of water 3 The actual power consumption of hydrogen is about 4.5-5.5kW·h. Theoretically, the efficiency of hydrogen production by electrolysis of water is about 50%, but the actual efficiency is much lower ...
