Wastewater-free reverse osmosis water generator

Abstract

The invention discloses two reverse osmosis water-making machines avoiding water waste. One reverse osmosis water-making machine adopts the structure that a water inlet one-way valve is arranged on a water inlet pipe; a water return pipe is connected onto the water inlet pipe in the front of the water inlet one-way valve; an air bag is arranged in a diaphragm shell; brackets are arranged between RO diaphragms and between grids. The other osmosis water-making machine adopts the structure that a water-inlet pressure water tank is arranged at the back of the water inlet one-way valve; the water return pipe is connected onto the water inlet pipe or a water main in the front of the water inlet one-way valve; a pure water cylinder-filling amount regulating valve is arranged on a pressure cylinder pure water pipe. The two reverse osmosis water-making machines are free of power, simple in structure, and low in failure rate and maintenance cost, and can serve as water purification machines avoiding water waste, reducing high-TDS water in the RO diaphragms in time, guaranteeing the quality of pure water, and prolonging the service life of the RO diaphragms.

Description

technical field [0001] The invention relates to a water production equipment based on the principle of reverse osmosis. Background technique [0002] One type of wastewater-free reverse osmosis water generator on the market is to use the high pressure of the water pump to press the concentrated water into the primary filter group for recycling, and to flush and restore other kitchen water. The disadvantages are that it needs electricity, complex structure, and high maintenance costs. The failure rate is high, and the water in the primary filter group with high TDS value restored by other kitchen water generally needs 7 times the raw water inflow to restore the same TDS value as the influent water. If the other water in the kitchen is less, it will cause pure water The water quality deteriorates and affects the life of the RO membrane; with the conventional low-pressure RO membrane and its membrane shell, no concentrated aquatic product water, and the method of washing the hi...

[0002] One type of wastewater-free reverse osmosis water generator on the market is to use the high pressure of the water pump to press the concentrated water into the primary filter group for recycling, and to flush and restore other kitchen water. The disadvantages are that it needs electricity, complex structure, and high maintenance costs. The failure rate is high, and the water in the primary filter group with high TDS value restored by other kitchen water generally needs 7 times the raw water inflow to restore the same TDS value as the influent water. If the other water in the kitchen is less, it will cause pure water The water quality deteriorates and affects the life of the RO membrane; with the conventional low-pressure RO membrane and its membrane shell, no concentrated aquatic product water, and the method of washing the high TDS value water in the membrane with kitchen water, the life of the RO membrane is extremely short, and pure water poor water quality

At present, there is also a water-saving pure water machine on the market, which uses an electric water pump to boost the pressure, and the control panel controls the regular discharge of concentrated water with high TDS value. The disadvantages are complex structure, high maintenance cost, high failure rate and limited water saving.
