Embodiment 1

[0024] The all-in-one machine for purifying pure water in this embodiment, such as figure 1 Shown includes a primary filter 20 , an electrolytic water purifier 10 and a reverse osmosis membrane device 30 . Electrolytic water purifiers such as figure 2 As shown, including a closed container 1 and a power supply (not shown in the figure), two pairs of cathode and anode electrodes parallel to each other and made of activated carbon material are arranged in the closed container 1, which are the first pair of cathode and anode electrodes 2, 3 and the second Pair of anode and cathode electrodes 4 and 5. A gap in the range of 0-20mm is maintained between each pair of electrodes, and the power supply supplies power to the two pairs of cathode and anode electrodes 2, 3, 4 and 5. The closed container 1 is provided with an interchangeable water inlet 6 and a water outlet 7, as well as a waste water outlet 8 perpendicular to the direction of water inlet and outlet; the water inlet 6 an...

Embodiment 2

[0032] The all-in-one machine for purifying pure water in this embodiment is a change on the basis of the first embodiment, except that it is the same as the first embodiment: Figure 4 As shown, the second electrolytic water purifier 11 is included, and the second electrolytic water purifier 11 has the same structure as the electrolytic water purifier 10; the concentrated water outlet of the reverse osmosis membrane device 30 is the same as the second electrolytic water purifier 11. The water inlet 6-1 of the second electrolytic water purifier is connected, and the water outlet 7-1 of the second electrolytic water purifier is connected to the water outlet 7 of the closed container 1 and communicated with the water inlet of the reverse osmosis membrane device 30; the second electrolytic water purifier 11 The waste water outlet 8-1 and the waste water outlet 8 of the electrolytic water purifier 10 are connected to the same waste water valve 12 and communicate with each other.

Embodiment 3

[0034] The all-in-one machine for purifying pure water in this embodiment is a change on the basis of the first embodiment, except that it is the same as the first embodiment: as follows: Figure 5 As shown, the concentrated water outlet of the reverse osmosis membrane device 30 is connected to a first waste water ratio (usually a restrictor valve) 40 and then connected to the water inlet three-way valve 14 of the primary filter 20. The ratio of source water and waste water formed on the 20 is mixed and electrolyzed again, so that the concentrated water (concentrated brine) formed in the reverse osmosis membrane device 30 flows back into the primary filter 20 and then flows through the electrolytic water purifier 10 for desalination (deionization), Finally, it enters the reverse osmosis membrane device 30 again for secondary reverse osmosis to produce pure water. In this way, the amount of wastewater discharged from the reverse osmosis membrane device 30 can be reduced, and th...

Abstract

The invention relates to a water cleaning and purifying all-in-one machine, and belongs to the technical field of water treatment. The all-in-one machine comprises a primary filter, an electrolytic water purifier and a reverse osmosis membrane device, wherein the electrolytic water purifier comprises a closed container and a power supply, at least one pair of cathode and anode electrodes which areparallel to each other and are made of activated carbon materials are arranged in the closed container, the power supply supplies power to the electrodes, and the closed container is provided with awater inlet, a water outlet and a waste water outlet perpendicular to the water inlet and outlet direction; a water outlet of the primary filter is communicated with a water inlet of the closed container, and a water outlet of the closed container is communicated with a water inlet of the reverse osmosis membrane device; the electrolytic water purifier has two working states of purification and waste discharge. The machine can be used for preparing pure water with the effects of purifying water quality, reducing water hardness, reducing the use cost of a reverse osmosis membrane and reducing wastewater discharge.

Description

technical field [0001] The invention relates to a pure water machine, in particular to a pure water machine which collects water purification, reduces water hardness and combines pure water production, and belongs to the technical field of water treatment. Background technique [0002] In areas with high hardness water quality in my country, drinking tap water contains a large amount of calcium salt and magnesium salt ions. Although hard water does not cause direct harm to health, it can bring a lot of troubles to life, such as scale formation on water appliances, and reduced washing efficiency of soaps and detergents. In order to remove calcium and magnesium ions in water, a water softener filled with ion exchange resin can be used, or a reverse osmosis pure water machine can be used. However, the effluent of the ion exchange water softener is not suitable for direct drinking, and the reverse osmosis pure water machine causes a large amount of waste water discharge, which ...
