Filter element washing protecting system in reverse osmosis water production system

Abstract

The invention discloses a filter core flushing protection system in a reverse osmosis water production system, which comprises a No. 1 check valve, a water bag, a backwash device, a No. 2 check valve, a reverse osmosis device, an RO reverse osmosis membrane and a waste water discharge valve. An RO reverse osmosis membrane is arranged in the internal working chamber of the reverse osmosis device, and the RO reverse osmosis membrane divides the internal working chamber of the reverse osmosis device into a clean water area and a concentrated water area that are independent of each other. The water outlet is connected to the water inlet of the backwashing device through a tee. The invention adopts the water bag to store purified water to realize micro-pressure backwash RO membrane flushing technology, discharges a small amount of concentrated water during the water production process, and rinses the RO membrane with the purified water stored in the water bag after the water production, which solves the problem of concentrated water remaining in the RO membrane The scaling problem in the water inlet channel can also dissolve the slight scaling generated during the water production process in time, reducing the scaling risk of the RO membrane, and greatly increasing the actual service life of the RO membrane while ensuring the water quality.

Description

technical field [0001] The invention relates to a reverse osmosis water production system, in particular to a filter core flushing protection system in the reverse osmosis water production system. Background technique [0002] With the dramatic changes of man-made and nature in recent years, the living environment has a great impact, especially the most basic factors of life, such as water and air. In order to ensure that the basic living environment of the people can be improved, all walks of life are taking care of the environment as the most basic factor of production. However, the improvement of the environment cannot be achieved overnight, which forces us to find ways to find some special tools and technologies to meet the basic needs of a healthy life under the existing conditions; Invention and development of drinking water treatment technology, etc. [0003] At this stage, water treatment technology has been honed and improved through invention, and there are gener...

Problems solved by technology

[0011] The above methods have shortcomings. Airbag flushing is first of all difficult to guarantee the quality stability of the airbag (uneven force, film welding), and the amount of clean water that can be stored and actually used is relatively small; the volume of the pressure tank is relatively small due to technical limitations. Large, narrow application, household machines can not be used at all, despite the large amount of clean water stored, in actual use, there will be a lot of clean water left after each flushing, which is easy to cause secondary pollution; adding water pumps and electrical components, waterways and circuits must be Changes, increase costs and are not easy to control, increase hidden dangers, and increase costs borne by consumers. The above methods are rarely adopted by companies, and the concept of water-cleaning membranes is still limited to a very narrow range.
