Water purification equipment

Abstract

The invention relates to water purification equipment. The equipment comprises a multi-way valve, a main cavity and an ozone generating device, the multi-way valve is connected to the main cavity in a matched mode and communicated with fluid in the inner cavity of the main cavity, the multi-way valve is provided with an air inlet and a water inlet, and the ozone generating device is communicated with the air inlet; when the multi-way valve is located at a target station, ozone generated by the ozone generating device enters the multi-way valve through the air inlet, liquid enters the multi-way valve through the water inlet, the ozone and the liquid are mixed in the multi-way valve, and formed gas-liquid mixed liquid enters the main cavity through the multi-way valve. By adopting the equipment, ozone can be introduced to assist in cleaning the filter material, the flux recovery rate of the filter material is improved, and the service life of the filter material is prolonged.

Description

technical field [0001] The present application relates to the technical field of water purification, in particular to a water purification equipment. Background technique [0002] With the improvement of living standards, whole house water purification products are being favored by users. As a category of whole-house water purification products, the central water purifier is mainly used to remove sediment, rust and residual chlorine in the water body. For central water purifiers composed of sand, carbon and other filter materials, the filter material will be polluted after a certain period of use, resulting in a decline in flux and performance. If it is not rinsed and restored, it will affect the service life. [0003] At present, the way to restore the flux is to wash with water, but for the filter material with rich microporous structure, the adsorption sites are not only located on the surface, but also located in the inner micropores.

Problems solved by technology

For the central water purifier composed of sand, carbon and other filter materials, the filter material will be polluted after a certain period of use, resulting in a decline in flux and performance. If it is not rinsed and restored, it will affect the service life

[0003] At present, the way to restore the flux is to wash with water, but for the filter material with rich microporous structure, the adsorption sites are not only located on the surface, but also located in the inner micropores. The adsorption in the micropores of the filter material If the site is covered by tiny particles, it will affect the effect of removing residual chlorine. However, conventional backwash water cannot enter the micropores of the filter material, and the effect of removing pollutants in the micropores is not good, resulting in incomplete cleaning of the filter material and low flux. The recovery rate is low, which affects the life of the filter material

In addition, the porous feature makes the filter material have good adsorption performance, and it is easy to breed bacteria and microorganisms when there is no water, which affects water quality and hygiene.
