Embodiment 1

[0018] Water purifier of the present invention can adopt as figure 2 In the shown system, the inlet of non-woven fabric and granular activated carbon combined filter element 11 is connected to tap water 1 through valve 2, the outlet of non-woven fabric and granular activated carbon combined filter element 11 communicates with the inlet of nanofiltration membrane module 7, and the inlet of nanofiltration membrane module 7 The outlet water passes into the water storage bucket 12, and the water storage bucket 12 communicates with the drainage system 15 with a timing automatic drainage function. Municipal tap water passes through non-woven fabric and granular activated carbon pre-treatment combination filter element 11 and nanofiltration membrane 7 successively, and the purified water enters the water storage tank 12 for storage. When the purified water stored in the water storage tank 12 exceeds the time set by the automatic drainage system 15 , Unused clean water can be complet...

Embodiment 2

[0025] Water purifier of the present invention can adopt as image 3 In the shown system, the inlet of non-woven fabric and granular activated carbon combined filter element 11 is connected to tap water 1 through valve 2, the outlet of non-woven fabric and granular activated carbon combined filter element 11 communicates with the inlet of nanofiltration membrane module 7, and the inlet of nanofiltration membrane module 7 Outlet water passes into water storage bucket 12, and water storage bucket 12 communicates with drainage system 15 with timing automatic drainage function, and sterilization system 14 communicates with water storage bucket 12 through low-pressure outlet water pump 13. Wherein the sterilization system 14 adopts a KDF filter. The low-pressure water outlet pump 13 can keep the water outlet flow rate above 2L / min, and the KDF filter can use a stainless steel filter column with a diameter of 22mm and a length of 100mm, and the packing density is 1.5g / cm 3 to 2g / cm...

Embodiment 3

[0032] Water purifier of the present invention can adopt as image 3 In the shown system, the sterilizing system 14 adopts ultraviolet lamps, the tap water passes through the non-woven fabric and granular activated carbon pretreatment combination filter element 11, the nanofiltration membrane 7, and the purified water enters the water storage tank 12 for storage, and finally passes through the low-pressure water outlet pump 13 and passes through the ultraviolet light. Lamp to sterilize.

Abstract

The invention discloses a water purifier, which comprises a non-woven fabric component communicated with tap water, a granular active carbon component communicated with the non-woven fabric component, a nano-filtration membrane component arranged in back of the granular active carbon component and communicated with the granular active carbon component, and a water storage barrel communicated with a water outlet of the nano-filtration membrane component. The water purifier not only reduces such components as a tap water booster pump, a pressure water storage tank, a postposition active carbon component, and the like, and effectively lowers the cost and energy consumption of the water purifier, but also can further remove bacteria in purified water and inhibit the growth of the bacteria, can reduce yielding water bacteria to the minimum content, and simultaneously can dissolve out proper amount of zinc element in a KDF filter material to have the additional efficacy of supplementing zinc.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a low-pressure nanofiltration water purifier device with a strong function of killing (inhibiting) bacteria. Background technique [0002] The common process of nanofiltration or reverse osmosis water purifier in the past is non-woven fabric, coarse filter granular activated carbon (GAC), fine filter granular activated carbon, tap water booster pump, nanofiltration membrane or reverse osmosis membrane, pressure water storage tank and Rear granular activated carbon. The reverse osmosis or nanofiltration membrane of this kind of water purifier has relatively high water inlet pressure requirements, and the water pressure of general municipal tap water cannot meet the requirements, so a booster pump with relatively large volume and power must be added, which means The power consumption of the water purifier has been greatly improved, and the consumption of resources has be...
