Water-saving membrane component and filter structure thereof

Abstract

The invention discloses a water-saving membrane component and a filter structure thereof. The water-saving membrane component comprises a center tube, a filter membrane component, an upper seal part and a lower seal part, and the filter membrane component is rolled centering on the center tube. The upper seal part seals the outer periphery of the upper end face of the filter membrane component to make the inner periphery, close to the center tube, of the upper end face, serve as a wastewater outlet. The lower seal part seals the inner periphery, close to the center tube, of the lower end face of the filter membrane component to make the outer periphery of the lower end face serve as a water inlet. Due to adoption of the water-saving membrane component, during filtering, raw water enters the outermost layer of the water-saving membrane component from the water inlet of the outer periphery of the lower end face and then spirally flows into the innermost layer of the water-saving membrane component from the outermost layer of the water-saving membrane component, pure water flows into the center tube, and waste water flows out from the wastewater outlet. The water-saving membrane component and the filter structure thereof have advantages of complete utilization of the filter membrane component, low loss, high pure water flux, less wastewater, uniformity in water feeding, long filter flow passage, effectiveness in filtration and the like.

Description

technical field [0001] The invention relates to the technical field of water purification and filtration, in particular to a water-saving membrane element and its filtration structure. Background technique [0002] With the development of society, people pay more and more attention to their own health, especially in drinking water. In order to drink clean and hygienic water, people invented the water purification filter. The core component of the water purification filter is the filter structure. There are many filter structures, among which the RO reverse osmosis membrane filter structure is often used. The existing RO reverse osmosis membrane filtration structure mainly includes a central tube and a membrane element wound on the central tube. During the filtration process using the RO reverse osmosis membrane filtration structure, the raw water generally adopts surface water inlet and side water inlet. No matter which method is used to feed water, there are the following ...

Problems solved by technology

The existing RO reverse osmosis membrane filtration structure mainly includes a central tube and a membrane element wound on the central tube. During the filtration process using the RO reverse osmosis membrane filtration structure, the raw water generally adopts surface water inlet and side water inlet. No matter which method is used to feed water, there are the following problems: the membrane element cannot be fully utilized, the flux of pure water is small, the amount of waste water is large, and the water inflow is uneven. The internal pressure is unbalanced, the filter channel is too short, resulting in poor filtering effect, etc.
