Embodiment 1

[0028] see figure 1 According to an embodiment of the present invention, a water purification system using RO membrane and wastewater solenoid valve descaling includes a municipal pipe network connection pipe 17, and the municipal pipe network connection pipe 17 is respectively connected to the ultrafiltration membrane through a pressure reducing valve 1 The filter element 8 is connected with the descaling container 15, and one side of the ultrafiltration membrane filter element 8 is connected with an activated carbon filter element 9, and the side of the activated carbon filter element 9 away from the ultrafiltration membrane filter element 8 is connected with the stabilizing pump 3 and the net filter element 8 respectively. The water outlet pipe 18 is connected, wherein the water outlet pipe 18 is provided with a flow meter 7, and one side of the pressure stabilizing pump 3 is connected with the reverse osmosis filter element 10 and the output end of the self-priming pump 14 ...

Embodiment 2

[0030] see figure 1 According to an embodiment of the present invention, a water purification system using RO membrane and wastewater solenoid valve descaling includes a municipal pipe network connection pipe 17, and the municipal pipe network connection pipe 17 is respectively connected to the ultrafiltration membrane through a pressure reducing valve 1 The filter element 8 is connected with the descaling container 15, and one side of the ultrafiltration membrane filter element 8 is connected with an activated carbon filter element 9, and the side of the activated carbon filter element 9 away from the ultrafiltration membrane filter element 8 is connected with the stabilizing pump 3 and the net filter element 8 respectively. The water outlet pipe 18 is connected, wherein the water outlet pipe 18 is provided with a flow meter 7, and one side of the pressure stabilizing pump 3 is connected with the reverse osmosis filter element 10 and the output end of the self-priming pump 14 ...

Embodiment 3

[0038] see figure 2 , when concrete implementation, for self-priming pump 14, can reduce the use of self-priming pump 14, therefore, the tap water of municipal pipe network passes through pressure reducing valve 1 through ultrafiltration membrane cartridge 8, Activated carbon filter element 9, solenoid valve 1, pressure stabilizing pump 3, reverse osmosis filter element 10 discharge pure water from the pressure switch 4, post-treatment filter element 11 from the pure water outlet pipe 19, and waste water from the other branch of the reverse osmosis filter element 10 Valve 5 discharges waste water, and bypass water inlet solenoid valve two 13, check valve two 16, descaling container 15, and check valve one 12 form a descaling system.

[0039] The working principle of the descaling system is as follows: the descaling container 15 is filled with a descaling agent in advance (the descaling agent can be sodium citrate, silicon phosphorus crystal, etc.), and the pressure of the con...

Abstract

The invention discloses a water purification system using an RO membrane and a wastewater solenoid valve for descaling and a water purifier. The system includes a municipal pipe network connection pipe, and the municipal pipe network connection pipe is connected to an ultrafiltration membrane filter element and a descaling container through a pressure reducing valve, an activated carbon filter element is connected to one side of the ultrafiltration membrane filter element, and one side, far away from the ultrafiltration membrane filter element, of the activated carbon filter element is connected to a pressure-stabilizing pump and a purified water outlet pipe; the purified water outlet pipe is provided with a flowmeter, one side of the pressure-stabilizing pump is connected to a reverse osmosis filter element and the output end of a self-priming pump, and the input end of the self-priming pump is connected to the descaling container; and the output end of a reverse osmosis filter element is connected to a post-treatment filter element and a wastewater discharge outlet, the output end of the post-treatment filter element is provided with a pure water outlet pipe, and the purified water outlet pipe and the pure water outlet pipe are both connected to a faucet. The system realizes the descaling of the surface of the RO membrane and the wastewater solenoid valve without disassembling a filter element to the maximum extent, and the service life of the water purifier is prolonged.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a water purification system and a water purifier using RO membranes and wastewater solenoid valves for descaling. Background technique [0002] The RO membrane in the reverse osmosis water purifier is the main filter element for filtering metal ions. Due to its high production technology requirements, in order to ensure the filtration effect, the imported RO membrane is generally used in the market, so the use cost of the RO membrane is high. Patent CN205133303U provides a reverse osmosis system with anti-scaling device. The anti-scaling device is loaded with anti-scaling agent. The anti-scaling agent and inorganic salt ions form a chelate to prevent the generation of inorganic salt precipitation, so it can effectively prevent the formation of inorganic salts. The membrane and valve of the water purifier are blocked. But the following technical issues: [0003] 1. The antiscal...
