Problems solved by technology

[0004] 1. Activated carbon central water purifier: The central water purifier with activated carbon as the main filter material can only reach the cleanliness of general domestic water, and the ability to eliminate bacteria is poor. The water filter material has low water purification ability and short service life, so the filter material needs to be replaced frequently
[0005] 2. Ultrafiltration membrane central water purifier: The central water purifier with ultrafiltration membrane as the main filter material can only guarantee the biological indicators of the effluent
[0008] These three central water purifiers can only provide purified water of a single quality regardless of the water quality

example 1

[0040] Example 1: Implementation example under countercurrent filtration mode

[0041] figure 1An example of the invention is given in the form of countercurrent filtration. The water purification chamber 2 is located on the upper part of the filter tank 1, and the filter bed 3 is located in the middle of the filter tank 1, which can be filled with various filter materials in layers. Top of tank 1. The top of the filter tank 1 is provided with an ultrafilter cartridge holder 6, and the external pressure type ultrafilter element 5 is connected to the end cap 51 with a standard bayonet, and the ultrafilter element is inserted into the water purification chamber 2 through the end cap. The end cover 51 is provided with a water hole 52 communicating with the water outlet of the ultrafilter element, and two layers of stepped sealing end surfaces are provided. On the deck 6, there are two layers of stepped sealing end faces corresponding to the end cover 51, and a water ring groov...

Abstract

The invention discloses a method and a device for realizing the quality-based water supply of a central water purifier. An ultrafiltration unit, which is easy to detach and replace, is integrated on the top part of the filter tank of the central water purifier, and the water purifier is also provided with a water outlet for directly drinking water filtered by an ultrafilter besides the water outlet for common purified water filtered by a filtering material. On the basis of keeping an original filtration path, a flow path from the common purified water to the water outlet is changed by flow channel planning so as to lead the common purified water to the ultrafiltration unit. By setting a reasonable flow channel inside diameter size, the flowing speed of water flowing in the ultrafiltration unit is improved and an ultrafiltration membrane can be cleaned effectively. A curved flow channel is adopted to adapt to the limitation on the length of an ultrafiltration core and the space in the tank. The invention provides a solution and device for channel planning for downflow filtration and reverse flow filtration and the implementation method of the ultrafiltration unit which is easy to detach and replace. In the invention, the quality-based water supply is realized by one set of central water purifier, and heavy-flow living purified water supply and heavy-flow and high-quality directly drinking water supply are realized.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a quality-separated water supply method for a central water purifier and a device thereof. Background technique [0002] For domestic water, water with different cleanliness is provided according to different purposes. Whole-house purification and direct drinking are the development direction of domestic clean water. [0003] The purification of the whole house is mainly realized through the central water purifier. At present, there are three basic types of central water purifiers: [0004] 1. Activated carbon central water purifier: The central water purifier with activated carbon as the main filter material can only reach the cleanliness of general domestic water, and the ability to eliminate bacteria is poor. The water filter material has low water purification ability and short service life, so the filter material must be replaced frequently. [0005] 2. Central water purifier w...
