Abstract

The invention discloses a purified water back-flow type water and energy conservation water purifier. The water purifier comprises a raw water end, a water inflow electrically operated valve, a filter element mechanism, a booster pump, water producing RO film and back-flow RO film which are connected in sequence through a pipeline, and further comprises a check valve, a purified water storage tank, a water-feeding pump and a micro waste water ratio combination solenoid valve. A water purification outlet of the water producing RO film is connected to a water return pipe and a water outlet pipe separately, the water return pipe is provided with the check valve, the water outlet pipe is provided with the purified water storage tank, and the water-feeding pump and a purified water tap. A concentrated water outlet of the water producing RO film is connected to a water inlet of the back-flow RO film; a purified water outlet of the back-flow RO film is connected to a purified water back-flow pipe, and the purified water back-flow pipe is connected to a water inlet of the booster pump; a concentrated water outlet of the back-flow RO film is connected to the micro waste water ratio combination solenoid valve, and the micro waste water ratio combination solenoid valve is connected to sewer discharge; the purified water storage tank is internally provided with a high water level float switch and a low water level float switch. The purified water back-flow type water and energy conservation water purifier can save water resources and reduce energy consumption, ensure the service life of the RO film, and effectively improve purified water quality at the same time.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a pure water return type water-saving and energy-saving water purifier. Background technique [0002] China is a country with scarce water resources. The limited water source is seriously polluted, and the water environment continues to deteriorate, seriously threatening the safety of drinking water in urban and rural areas. Therefore, surface water and groundwater must be purified before they can be used as drinking water. Now the core drinking water treatment technology is membrane filtration technology. One of them is reverse osmosis membrane (RO membrane) filtration. The filter pore size is 0.0001 micron, which can completely remove all harmful substances in water, and only keep water molecules to produce pure water. Its effect is the best solution in membrane treatment, but its The biggest disadvantage is that a large amount of waste water (concentrated water) need...
