Description

Technical Field

[0001] The utility model belongs to the technical field of membrane filtration equipment system, and more specifically relates to a fast-assembly columnar membrane component and a membrane filtration equipment system. Background Art

[0002] Column membrane modules are similar to door column products, so they are also called column membrane modules or pressure membrane modules. Column hollow fiber membrane modules are widely used in drinking water purification, industrial water treatment, beverages, biology, food, medicine, environmental protection, chemical industry, metallurgy, petroleum and other water treatment industries.

[0003] The column membrane assembly is installed on the membrane frame (frame, outer frame) to form a membrane stack (ultrafiltration host). The membrane stack consists of a membrane assembly, a membrane frame and a pipeline. The ultrafiltration host is placed indoors, with an ambient temperature of 5-45 degrees Celsius. The raw water is pumped into the column membrane assembly of the ultrafiltration host by a centrifugal pump. The small molecules of water to be purified and water enter the membrane through the small holes on the membrane wire wall. Due to long-term operation, pollutants such as fibers and colloids that need to purify water adhere to the surface of the membrane wire, clogging the small holes on the membrane wire wall, causing the holes through which the membrane wire can pass water to gradually become smaller or even blocked, resulting in a decrease in water permeability. In order to reduce the blockage of membrane holes, an air inlet pipe is installed under the membrane assembly, and aeration is performed regularly so that the membrane wires on the membrane assembly are scrubbed with air and water under the action of water and air, and the pollutants on the surface of the membrane wire are removed to ensure the long-term stable operation of the membrane stack.

The column membrane assembly can only be installed after the membrane frame and the pipeline are installed. The installation of the membrane assembly is carried out one by one, which has a large installation workload, high installation accuracy requirements, and difficulty in debugging and installation.
