The problem that the water purification outlet taste of the existing water purifier is acidic is pointed out based on the background technology. The invention provides a water purification system, which adopts a degassing membrane device to remove carbon dioxide in the effluent of a reverse osmosis filter element so as to weaken the acidity of the effluent and improve the taste of the effluent.
The working principle of the degassing membrane device is as follows: the water flow passes through the inner core of the degassing membrane device under a certain pressure, and the gas outside the inner core is pumped by a vacuum pump to form a certain negative pressure, so that the gas in the water passing through the inner core continuously overflows outwards from the water through the inner core under the negative pressure effect, thereby achieving the purpose of removing the gas in the water.
The present inventors have found that a negative pressure is formed by water flowing through the outside of the core at a high speed to discharge the gas in the water flowing through the core to the outside, thereby replacing the method of generating a negative pressure using a vacuum pump. According to the invention, the carbon dioxide in the purified water is discharged by being connected into the water purification system in the mode, so that the PH of the purified water is increased, the acidic taste of the purified water is reduced, and the water outlet quality of the purified water is improved; on the other hand, the water purification system is assembled without adopting a vacuum pump, so that the installation components are reduced, the assembly cost is reduced, and the user experience is better.
