System for obtaining purified water in tap water use process

Abstract

A system for obtaining purified water in a tap water use process is characterized in that a main pipeline is provided with a turbine flow meter, a water pipeline of the main pipeline is provided with tap faucets, a tap water branch pipeline is provided with a water inlet solenoid valve, a booster pump, a pre-treatment purifying apparatus formed by a mechanical filter and an active carbon filter, a reverse osmosis membrane element, a water storage tank and a purified water faucet, a flushing valve and a concentration proportioning valve are installed at a front concentrated water side of the reverse osmosis membrane element, the flushing valve and the concentration proportioning valve are connected with a buffer water tank through a front check valve, and the buffer water tank is communicated with the water pipeline through a rear check valve; and the main pipeline is provided with a conical valve and a main pipe check valve, and a pressure sensor is arranged at the intersection of the main pipeline and the water pipeline. The method allows home freshwater to be completely utilized, accords with the saving, emission reduction, environmental protection and low carbon consumption principles, improves the utilization efficiency, reduces wastes, improves the cost effectiveness of a user, and improves the social benefit.

Description

technical field [0001] The invention belongs to the technical field of household tap water purification and treatment, and relates to a new type of pure water preparation method that reduces waste, in particular to a control process for a system that obtains pure water from tap water, and is especially suitable for new types of civil buildings, institutions , Hospitals and other public buildings, new rural construction, suitable for fresh water shortages and densely populated areas, one-time completion of piping and installation during construction and decoration. Background technique [0002] The pure water machine, with NASA's reverse osmosis filtration technology as the core, is currently recognized worldwide as the most thorough, safest and most widely used water purification device. The pure water machine is easy to install, the model is small and compact, and does not take up a lot of space. Almost every household can install one under the kitchen, and the water treate...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem of not wasting water resources or reusing waste water when producing pure water, and proposes a reverse thinking, which does not solve the problem of waste water by using the traditional method of making pure water, but How to produce a relatively small amount of pure water while producing the so-called waste water, and design a method to obtain pure water from the process of using tap water. Using reverse thinking, the direct drinking water consumed in the preparation of pure water as the main product, while purified water is stored as a by-product, which complies with the concept of waste water ratio
