Description

Anti-pollution reverse osmosis membrane component

Technical Field

The utility model relates to a water filtration technology field especially relates to antipollution reverse osmosis membrane subassembly.

Background

The reverse osmosis technology is widely applied to the water treatment industry, and the working principle of the reverse osmosis technology is that the pressure difference between the front and the back of a membrane is used as a driving force, and the separation of a solvent and a solute is achieved by utilizing the selective permeability of the membrane. The reverse osmosis membrane subassembly of current filter core includes the center tube, along the reverse osmosis membrane of center tube circumference winding at the center tube to and the winding is at the seal membrane of reverse osmosis membrane periphery. When the water purifier works, raw water enters from one end of the reverse osmosis membrane, in the process of flowing along the axial direction, one part of water enters the central tube along the radial direction after being filtered by the reverse osmosis membrane, and the other part of water flows into the wastewater waterway from the other end of the reverse osmosis membrane along the axial direction. Due to the selective permeability of the membrane, solutes in the influent water are concentrated on the surface of the reverse osmosis membrane to form precipitates which adhere to the surface of the reverse osmosis membrane or block the pores of the reverse osmosis membrane, resulting in contamination of the reverse osmosis membrane and a decrease in the permeability.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an antipollution reverse osmosis membrane subassembly, this antipollution reverse osmosis membrane subassembly on the basis of guaranteeing into the water velocity of flow, the dirt of the mesh that significantly reduces is stifled, can be at the relatively poor condition extension membrane subassembly of raw water quality of water life, guarantee the effect of water treatment.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides an antipollution reverse osmosis membrane module, includes the center tube and twines the membrane unit on the center tube, the membrane unit is located the middle part of center tube for the both ends of center tube are outwards extended respectively in two terminal surfaces of membrane unit, the outside of membrane unit one end is intake the side, and the outside of the other end is the drainage side, the one end that the side was kept away from into to the center tube is for producing the water end, the membrane unit includes the net and the filter membrane of intaking of superpose, the mesh of the net of intaking is parallelogram, just an acute angle orientation of mesh is intake the side.

The further improved scheme in the technical scheme is as follows:

1. in the above scheme, the meshes of the water inlet grid are rhombic.

2. In the scheme, the acute angle of the mesh is 65-85 degrees.

3. In the scheme, the two ends of the membrane unit are connected with the central pipe through bonding.
