Problems solved by technology

[0010] However, this wrapping process has difficulties in changing the labels on the wrapped products, and requires independent wrapping equipment and a dedicated curing room
In addition, this package has the following problems: the difficulty of cleaning the package equipment, the need for finishing work on the outside of the product, and the need to install end caps on the components
[0011] In this conventional encapsulation process, the use of an encapsulation solution containing epoxy resin results in a long curing time of about 6 to 12 hours due to the humidity of the epoxy resin, resulting in difficult handling work
Since the curing degree and curing time depend on the mixing ratio of epoxy resin and curing agent in the coating solution, the problem with this coating process is that the mixing ratio is difficult to control, and improper mixing ratio of the coating solution will result in the scrapping of the solution , resulting in additional costs for waste disposal
[0014] In order to solve the problem of the wrapping process in the traditional membrane module manufacturing process, the inventors of the present invention have succeeded in providing a plastic molded body that can completely wrap the membrane module

Embodiment 1

[0075] A 140 micron thick porous polysulfone support comprising a non-woven backside was immersed in an aqueous solution containing 2% by weight m-phenylenediamine (MPD) and 0.2% by weight 2-ethyl-1,3-hexanediol for 40 seconds, and removed to remove excess aqueous solution. Subsequently, the coated support was immersed in a solution containing 0.1% by weight of trimesoyl chloride (trimesoyl chloride, (TMC)) for one minute (wherein the trimesoyl chloride was dissolved in a registered trademark of (In the solvent of Exxon company), and take out and remove excess organic solution, to prepare polyamide reverse osmosis composite membrane.

[0076] The polyamide reverse osmosis composite membrane, the warp-knitted fabric and the mesh are sequentially wound from the core to the outside to form a spiral membrane module.

[0077] The spiral membrane module was housed in one of a pair of semi-cylindrical tubes integrally formed with end caps and made of polypropylene resin, and covere...

Embodiment 2

[0080] The implementation steps are the same as those described in Example 1, except that the spiral membrane assembly is incorporated into a pair of semi-cylindrical members 10 and 20 integrally formed with end caps and made of acrylonitrile butadiene styrene copolymer resin. the same way.

Embodiment 3

[0082] Instead of the semi-cylindrical pipe integrally formed with end caps, a cylindrical member 30 made of polypropylene resin of 1 m in length was prepared by extrusion molding. Pack the spiral membrane assembly in this cylindrical tubular molded body, and end cap 31 is threadedly installed on the two ends of cylindrical tubular molded body by threaded fastener 32 ( Figure 7 shown). Here, a spiral membrane module was prepared in the same manner as in Example 1.

Abstract

The present invention relates to a tubular molded body capable of full-wrapping a membrane module, and an industrial filter assembly using the same. The tubular molded body of the present invention is a molded body consisting of a transparent plastic material and having a constant outer diameter that protects the membrane module through a simple manipulation using a physical fastening means to minimize the space for water stagnation, and prevents the accumulation of Mg2+ and Ca2+ to avoid a rise of the differential pressure caused by contaminants. Furthermore, the present invention provides an industrial filter assembly including a tubular molded body encasing from one end to the other of the membrane module, an industrial facility vessel protecting the exterior of the tubular molded body.

Description

technical field [0001] The present invention relates to a tubular molded body that can completely wrap a membrane module and an industrial filter device using the tubular molded body, more particularly, to a tubular molded body and an industrial filter using the tubular molded body device wherein a tubular molded body of transparent plastic material can be used as an alternative to conventional wrapping processes using wrapping solutions through simple handling with physical fasteners to protect membrane components simply by assembly, and The time and cost required for the wrapping process are reduced by eliminating the need for separate equipment necessary for the wrapping process, and the stagnation of supply water is minimized by installing the product, which is formed by forming in the tubular molded body The holes on the top solve the problem of water stagnation and improve the pressure difference. Background technique [0002] The membrane module manufacturing process...
