Water-saving electricity-saving reverse osmosis water purifying machine

Abstract

A water and power saving type of a reverse osmosis water purifier consists of a pretreatment filter core, a high pressure pump, a reverse osmosis filter core, a waste water ratio, ectromagnetic valve, an atmosphere intermediate water tank, and an atmosphere pure water tank. After the water is processed by the pretreatment filter core, the water enters into the atmosphere intermediate water tank; the high pressure pump absorbs the water from the atmosphere intermediate water tank; the outlet water from the reverse osmosis filter core enters into the atmosphere pure water tanks; after the pressure of the discharging sewage from the reverse osmosis filter core is decreased by the waste water ratio, the waste water returns to the atmosphere intermediate water tank. Compared with the prior art, the water and power saving type of a reverse osmosis water purifier has the advantanges that the invention puts the waterless idle roll and frequent starting and stopping phenomena of the high pressure pump to an end; the high pressure pump has a long using life, a power saving capability and a high utilization efficiency of the raw water; the invention can provide a dual water supply function and realize the wastewater zero discharge with a stable operating system and a low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water-saving and power-saving reverse osmosis pure water machine. Background technique [0002] Reverse osmosis is a relatively mature pure water manufacturing technology. At present, the utilization rate of raw water for large-scale reverse osmosis water production equipment is relatively high, while the utilization rate of raw water for small-scale reverse osmosis water production equipment is low, especially for those using a single reverse osmosis filter element. Equipment, such as household reverse osmosis pure water machines sold in large quantities on the market, the water utilization rate is only 25%, or even lower, that is, the production of 1m 3 Purified water needs to consume at least 4m 3 tap water. For today's day by day scarcity of fresh water resources, this kind of waste is really a pity. [0003] Known technology 1: Figure 1 is a schematic diagram of...

AI Technical Summary

Problems solved by technology

[0007] 2. The high-pressure pump (3) has a heavy load and long running time, which not only affects the service life but also wastes electric energy

In this way, the back pressure at the water outlet of the reverse osmosis filter element (4) is gradually increased, and the load on the high pressure pump (3) is gradually increased, making it more and more difficult to carry out the filtration process, and the water outlet flow rate will also become smaller and smaller accordingly. , which prolongs the running time of the high pressure pump (3)

Its consequence is not only affecting the service life of the high pressure pump (3) but also wasting electric energy

[0009] 3. High manufacturing cost

Both of these increase the manufacturing cost of the water storage tank (6)

[0012] 4. The high pressure pump (3) may be damaged due to idling without water or frequent start and stop

[0018] 1. Problems such as short service life of high-pressure pumps, waste of electric energy, inability to prevent high-pressure pumps from idling without water and frequent start-stops, high manufacturing costs still exist, and due to the increase of the concentrated water pressure storage tank (14), the manufacturing costs further increase

[0019] 2. The system is unstable

[0023] 1. It cannot eliminate the high-pressure pump (3) without water idling phenomenon, and cannot solve the problems of high-pressure pump (3) short service life and waste of electric energy

[0024] 2. The system is unstable

When the tap water pressure is high, the back pressure at the outlet of the wastewater ratio (10) will increase accordingly, resulting in poor discharge of concentrated water, increasing the load on the high-pressure pump (3), and affecting the normal operation of the high-pressure pump (3); when the tap water pressure When the water pressure is low, it is difficult for the water pressure to overcome the filtration resistance of the pretreatment filter element (2), so that negative pressure may appear at the inlet of the high-pressure pump (3), which will cause the high-pressure pump (3) to run dry without water or start and stop frequently, affecting the high pressure. Pump (3) running normally
