Connecting device of dead-cavity-free membrane shell

Abstract

The invention discloses a connecting device of a dead-cavity-free membrane shell, and belongs to the technical field of water treatment. The connecting device is characterized in that one end of the shell is provided with raw water inlets, the other end of the shell is provided with concentrated water outlets with the same number as the raw water inlets, the shell further comprises four membrane shells, end covers are arranged at the top of the membrane shells, and the end covers are also jointly connected with a purified water outlet in a penetrating manner. The invention provides a connecting device of the dead-cavity-free membrane shell, which is simple in structure, can effectively solve the problem of non-uniformity when water flow passes through the membrane shells, can save installation space and fully utilize water resources, and has the characteristics of low input cost, low operation cost and convenience in use.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a connection device for a membrane shell without a dead space. Background technique [0002] At present, due to the unreasonable structural design of the reverse osmosis membrane shell used for the preparation of medical pure water, a dead space is formed between the reverse osmosis membrane in the membrane shell and the membrane shell body, and the accumulated water cannot be discharged. Pure water, especially the preparation quality of pure water for hemodialysis. The specific reason is that the membrane shell adopts the water inlet method of top in and bottom out. The internal structure of the membrane shell leads to a dead space in the membrane shell. In this way, the water flow cannot pass through the membrane shell evenly, resulting in no water flow in the back area of ​​the water outlet. Contents of the invention [0003] The purpose of the present invention is ...

[0002] At present, due to the unreasonable structural design of the reverse osmosis membrane shell used for the preparation of medical pure water, a dead space is formed between the reverse osmosis membrane in the membrane shell and the membrane shell body, and the accumulated water cannot be discharged. Pure water, especially the preparation quality of pure water for hemodialysis

The specific reason is that the membrane shell adopts the water inlet method of top in and bottom out. The internal structure of the membrane shell causes a dead space in the membrane shell. In this way, the water flow cannot pass through the membrane shell evenly, resulting in no water flow in the back area of ​​the water outlet.
