Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrafiltration membrane equipment technology, specifically an ultrafiltration membrane module for ship water treatment. Background Technology
[0002] Ultrafiltration membrane modules for marine water treatment are key equipment in shipboard water treatment systems. They enable the separation and purification of different substances through ultrafiltration membranes. Separation occurs through the sieving action of the ultrafiltration membrane driven by a pressure difference. The ultrafiltration membrane has numerous uniform micropores. When raw water passes through the membrane surface under certain pressure, water molecules and small solute molecules permeate through the membrane, becoming the permeate, while suspended solids, colloids, microorganisms, and large organic molecules—particles larger than the membrane pore size—are retained, thus achieving ultrafiltration.
[0003] After a period of use, the ultrafiltration membrane in marine water treatment modules may become clogged. Currently, existing marine water treatment ultrafiltration membrane modules are not able to efficiently backwash the internal ultrafiltration membrane during use. Utility Model Content

One end of the inner side of the ultrafiltration inlet seat body 20 has an inner annular groove 22, and one end of the outer side of the ultrafiltration inlet seat body 20 has an outer annular groove 23. One end of the inner annular groove 22 has an ultrafiltration inner inlet hole 24, and one end of the outer annular groove 23 has an ultrafiltration outer inlet hole 25.

The inner annular groove 22, the outer annular groove 23 and the ultrafiltration inlet pipe 26 are connected inside the ultrafiltration inlet seat 20. Multiple sets of ultrafiltration inner inlet holes 24 and ultrafiltration outer inlet holes 25 are provided.
[0026] The above scheme is adopted: by closing the solenoid valves at the ultrafiltration outlet flange 14 and the ultrafiltration inlet flange 28, the purified water is pumped into the ultrafiltration membrane module through the backwash flange 15 and the forward flush flange 29 by the flushing equipment. At this time, the flushing water is pumped into the ultrafiltration inner inlet hole 24 and the ultrafiltration outer inlet hole 25 through the inner annular groove 22 and the outer annular groove 23 connected to the ultrafiltration inlet pipe 26 for forward flushing. At the same time, the flushing water is pumped into the ultrafiltration membrane module through the backwash flange 15 and then pumped into multiple sets of ultrafiltration membrane rods 4 through the cavity between the ultrafiltration outlet seat 1 and the ultrafiltration inlet seat 20 for backwashing.

[0029] The working principle of this utility model is as follows: During use, the ultrafiltration outlet flange 14 is first connected to the outlet pipeline via a solenoid valve; the backwash flange 15 is connected to the flushing pipeline via a solenoid valve; the ultrafiltration inlet flange 28 is connected to the inlet pipeline via a solenoid valve; the forward flush flange 29 is connected to the flushing pipeline via a solenoid valve; and the flushing outlet flange 51 is connected to the sewage discharge pipeline via a solenoid valve.

At this time, due to pressure, the wastewater is filtered through the ultrafiltration membrane rod 4, and the purified water flows out from the outlet end of the ultrafiltration membrane rod 4 into the space between the ultrafiltration inlet seat 20 and the ultrafiltration outlet seat 1. Inside the cavity, the ultrafiltration liquid flows into the ultrafiltration liquid outlet pipe 12 and the ultrafiltration liquid outlet tee 13 and is then pumped out through the ultrafiltration liquid outlet flange pipe 14. When the ultrafiltration membrane rod 4 becomes clogged after a period of use, the solenoid valves at the ultrafiltration liquid outlet flange pipe 14 and the ultrafiltration liquid inlet flange pipe 28 are closed. The clean water is then pumped in through the backwash flange pipe 15 and the forward wash flange pipe 29 by the flushing equipment. At this time, the flushing water is pumped in through the forward wash flange pipe 29 and pressurized through the inner annular groove 22 and the outer annular groove 23 connected to the ultrafiltration liquid inlet pipe 26 and then flows out into the ultrafiltration outer sleeve 3 for forward flushing. At the same time, the flushing water is pumped in through the backwash flange pipe 15 and then pumped into multiple sets of ultrafiltration membrane rods 4 through the cavity between the ultrafiltration liquid outlet seat 1 and the ultrafiltration liquid inlet seat 20 for backwashing. This can achieve more efficient flushing of the ultrafiltration membrane module. Finally, the flushed wastewater flows out through the flushing liquid outlet flange pipe 51.
