Problems solved by technology

With the aggravation of water pollution, especially the increasing number of heavy metal pollution incidents, there is a safety risk that the electrolysis with ultrafiltration as the core of water purification cannot remove heavy metals, and the direct use of electrolysis to remove heavy metals is harmful to the electrodes used in electrolysis, The pH value of the solution, the time of electrolysis, and the concentration of ions all have high

Embodiment 1

[0024] see figure 2 , in a preferred embodiment of the present invention, the purification device 1 includes a first pp cotton filter element 11, a coconut shell activated carbon filter element 12 and a second pp cotton filter element 13, wherein the first pp cotton filter element 11 can be selected from 5 μm pp cotton, and The second pp cotton filter element can be made of 1 μm pp cotton. The first pp cotton filter element 11 can retain suspended matter such as rust and sand in tap water, and then pass through the coconut shell activated carbon filter element 12 to adsorb organic matter in the water and reduce water pollution. Chromaticity and smell, after this water flow passes through the second pp cotton filter element 13 again, plays further filtering effect, and can stop the activated carbon powder from leaking.

[0025] A first solenoid valve 61 is provided between the purification device 1 and the heavy metal removal device 2 , and a second solenoid valve 62 and a thi...

Embodiment 2

[0030] see image 3 , In this embodiment, the difference from the second embodiment above is that nanofiltration equipment 21' is used instead of reverse osmosis equipment 21 in the heavy metal removal device 2'.

Embodiment 3

[0032] see Figure 4 , in this embodiment, the purification device 1', in addition to the above-mentioned first pp cotton filter element 11, coconut shell activated carbon filter element 12 and second pp cotton filter element 13, also includes an ultrafiltration filter element 14, which is connected to the second pp cotton filter element. After the cotton filter element 13, preferably, a 0.01 μm ultrafiltration filter element is used to intercept and remove turbidity, chromaticity and macromolecular organic matter in the water. Sour water recycling device 4 is returned to purification device 1 '.

[0033] After the municipal tap water pretreatment is completed, it enters the heavy metal removal device 2". In this embodiment, the heavy metal removal device 2" includes an electrodialysis device 21". The membranes and the water channels between them run through the whole electrodialysis device.

[0034]The water treated by the electrodialysis device 21" is divided into three ty...

Abstract

The invention discloses a water ionizer capable of effectively removing heavy metals. The water ionizer comprises a purification device and an electrolysis device which are connected through a pipeline. The water ionizer further comprises a heavy metal removal device arranged between the purification device and the electrolysis device and an acidic water recycling device; acidic water generated after the electrolysis of the electrolysis device is communicated to the acidic water recycling device; the water outlet of the acidic water recycling device is connected to the purification device or the heavy metal removal device. By performing heavy metal removal treatment on the water entering the electrolysis device in advance, the potential hazards caused by heavy metal pollution are effectively removed, the safety of electrolytic raw water and the drinking safety of alkaline electrolytic water are ensured, the electrolysis device can be protected, and the service life of an electrode can be prolonged; the acidic water can be recycled and flows back to the purification device or the heavy metal removal device to be purified or electrolyzed again, so that the recovery rate of the water is increased, the utilization rate of the heavy metal removal device is increased, and the efficient utilization of water resources is realized.

Description

technical field [0001] The invention relates to an electrolyzed water machine, in particular to an electrolyzed water machine capable of effectively removing heavy metals. Background technique [0002] With the improvement of living standards, the pursuit of health is getting higher and higher, and the health care function of electrolyzed water is becoming more and more accepted by people. Water-lonizer is one of the kitchen water appliances in the 21st century. One of the most leading household appliances in the future. Use pre-filtration and core electrolysis technology to remove residual chlorine, impurities and heavy metals in tap water from the source. The tap water that needs to be boiled before drinking is converted into electrolyzed reduced water that meets the "World Health Organization" good water standard, which can be drunk directly. It is more in line with the needs of the human body than tap water, and can regulate body functions and improve sub-health. Moreo...
