EXAMPLE six
As shown in fig. 5, the present invention provides a specific water purification apparatus, which divides the water path entering the electric purification membrane stack (i.e. the treatment chamber group 10, the first electrode chamber 302 and the second electrode chamber 304) into 4 paths, and 2 paths are independent electrode water inlets and directly discharged into a waste water tank 904; 2, membrane stack purification and wastewater inlet are carried out, and the pure water is finally discharged and drunk through a post-filter element (i.e. a post-filter 914) and an instant heating module (i.e. a heating device 916); the wastewater drains directly into the wastewater tank 904.
The main working principle of this embodiment is: a self-priming pump (namely a pump body 912) sucks water from a raw water tank 902, the water enters a front filter element (namely a front filter element 910), the water enters a membrane stack after being divided into 4 paths, and 2 paths of water respectively enter electrode chambers (namely a first electrode chamber 302 and a second electrode chamber 304) on two sides of the membrane stack through flow proportioners (namely a first proportional flow valve 806 and a second proportional flow valve 808), and then are directly discharged to a waste water tank 904; the 2 paths of water entering the membrane stack respectively pass through a flow regulating valve (namely a first flow valve 802 and a second flow valve 804) to form a path of high-flow pure water and a path of low-flow waste water to enter the membrane stack, and the formed pure water and waste water pass through a four-way reversing valve (namely a four-way valve 70) through an electric purification process, so that the pure water always flows through a pure water waterway to enter a post-filter element (namely a post-filter 914) during forward operation and reverse operation and is discharged by an instant heating module (namely a heating device 916) for drinking; the waste water is discharged from the waste water pipeline all the time, and the whole electric purification process is completed.
The change of the desalination rate effect of the electric purification membrane stack is realized by adjusting the voltage, and the adjustable treatment of different TDS (Total dissolved solids) and temperatures is realized by matching with the instant heating module.
In summary, according to the water treatment device and the water purification apparatus provided by the invention, the independent first water inlet pipe and the independent second water inlet pipe are arranged, so that the water path flowing into the electrode and the water path flowing to the treatment chamber can be independently isolated, and the possibility that the electrode material is precipitated or dropped to influence the water quality due to long-time use can be reduced.
