Zero discharge water purifier

Abstract

The invention belongs to the field of water purifiers and particularly relates to a zero discharge water purifier. Core parts of the zero discharge water purifier include a four-way three-channel electromagnetic valve and a concentrated backwater pressure tank, wherein the four-way three-channel electromagnetic valve is connected to a domestic water pipeline in series; after the water purifier is electrified to generate water, a longitudinal path of an electromagnetic directional valve is an open path while an A-B path of the four-way three-channel electromagnetic valve is a closed path so as to form paths A and B which are not mutually communicated; a lower joint of the path A is connected with a transfer joint connecting seat, and an upper joint of the path A and an upper joint of the path B are connected with a longitudinal joint installation seat; the path A is communicated with a municipal water pipe so as to provide raw water for the water purifier; the path B treats the water in the backwater pressure tank and self-flushing backwater is communicated with the domestic water pipeline by virtue of a backwater supply pipe so as to re-enter into the rank of domestic water. By adopting a zero discharge technical scheme, the water purifier is used for solving the long-standing problem which puzzles the water purifying industry for a long time, so that the precious water resource is fully used and the water purifier is environmental friendly and energy-saving.

Description

technical field [0001] The invention belongs to the field of water purifiers, in particular to a discharge-free water purifier. Background technique [0002] The water production rate of the water purifier is between 1:4----1:1. In other words, the water purifier has a large part of the treated residual water in the water production process. Because this residual water is still good domestic water, it is a great waste to discard it, and it is also difficult to recycle it. Repeated filtration, increase the water production rate, and set up another container for storage... In short, the troublesomeness of backwater treatment is self-evident; if it is directly discharged into the sewer, it is not a national policy to waste precious water. [0003] Purpose of the present invention, solve above-mentioned difficult problem exactly, open a kind of water purifier with self-washing and non-discharging function to the society. Contents of the invention [0004] The invention belon...
