Multi-stage composite deep filtration high-water-efficiency water purifier and working method thereof

Abstract

The invention relates to a multi-stage composite deep-filtration high-water-efficiency water purifier and a working method thereof, and the multi-stage composite deep-filtration high-water-efficiency water purifier comprises a first-stage composite filter element, a second-stage polypropylene melt-blown filter element, a third-stage reverse osmosis membrane filter element, a fourth-stage activated carbon filter element, a water storage barrel and a monitoring instrument system, the tap water inlet pipe, the first-stage composite filter element, the first water pipe, the second-stage polypropylene melt-blown filter element and one end of the second water pipe are sequentially connected; one end of the second water pipe is connected with one end of the third water pipe and one end of the fourth water pipe through the first three-way joint. According to the multi-stage composite deep filtration high-water-efficiency water purifier and the working method thereof, the structural design is reasonable, four-stage filter elements are adopted, pollutants in a water body can be effectively removed, the discharged pure water reaches the national drinking water standard, the effects of internal flushing and external discharging are achieved, the situation that the flow rate and the recovery rate of the pure water are too low is avoided, water resources are saved, and the service life of the water purifier is prolonged. The quality of purified and filtered water can be monitored in real time, the working method is intelligent, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of pure water machines, and in particular relates to a high-efficiency pure water machine with multi-stage composite deep-layer filtration and a working method thereof. Background technique [0002] With the improvement of people's living standards and the deterioration of drinking water quality due to the increasingly serious environmental pollution, people have put forward higher requirements for drinking water. Water dispensers and bottled water entered the homes of ordinary people in the late 1990s, but as a new product, the concept of pure water dispensers is not yet familiar to the majority of Chinese consumers. The pure water machine is a terminal water purification equipment. Generally, tap water is used as raw water to filter out harmful substances in the raw water and process pure water that can be directly consumed. [0003] The pure water machine in the prior art has the following problems: 1. W...

Problems solved by technology

[0003] The pure water machine in the prior art has the following problems: 1. When preparing a cup of pure water, 3 cups of concentrated water will be drained, and the water production rate (recovery rate) is only 25%, or even lower, which is a waste of water Yes, and my country is a country where water resources are particularly scarce, so it is a pity that so much concentrated water is discharged in vain; 2. There is a lack of instruments for monitoring the quality of water production. High-efficiency pure water machine with composite depth filtration and its working method

[0004] The Chinese patent application number is CN200710124808.0, which discloses a pure water machine and a working method of the pure water machine. The purpose is to keep the filter element clean through regular flushing of the pre-treatment device and real-time flushing of the post-treatment device. Severe waste and lack of instruments to monitor water quality
