Description

Tubular membrane module structure and packaging method thereof

The present invention relates to a tubular membrane module, and more particularly to a tubular membrane module structure and a packaging method thereof.

Tubular membrane is a filtration method that uses tangential flow (also known as cross flow). Because the flow direction is parallel to the tube wall, the pollutants blocked by the tube wall are carried away by the pollution source, effectively solving the degree of blockage and improving the filtration efficiency. Compared with other membrane structures, tubular membrane has a larger application field and development prospects. When used, the membrane tubes are assembled into bundles according to different model requirements and placed in plastic or stainless steel membrane shells for positioning and packaging to form tubular membrane modules. When used, under the push of pressure difference, the solution and small solute particles in the feed liquid are filtered from the high-pressure feed liquid side to the low-pressure side. The liquid obtained is called permeate. This process can achieve the purpose of purifying, separating and concentrating the solution.

It is known that the tubular membrane assembly is to place a bundle of multiple tubular membranes on a fixture, and use the fixture to inject glue at one end of the multiple tubular membranes and bond them to the inner surface of the membrane shell. The end of the tubular membrane and the glue form a parallel shape, and then the multiple tubular membranes are assembled in the tubular membrane outer shell, and the other end of the multiple tubular membranes is fixed to the other end of the fixture and then injected with glue. After the glue hardens, the fixture is removed to complete the packaging. This method of directly bonding and fixing the two ends of the tubular membrane to the inner surface of the membrane shell has poor bonding strength and cannot provide good protection for the tubular membrane. It is easy to cause deformation and damage of the tubular membrane and the fall of glue due to water pressure and continuous impact on the end surface, resulting in filtration failure and shortening the life of the tubular membrane assembly.

When the tubular membrane is encapsulated in the tubular membrane shell, one or both ends of the tubular membrane are fixed on the inner surface of the membrane shell of the tubular membrane shell. When the tubular membrane module is working, the joint between the tubular membrane and the membrane shell is easily deformed or even damaged. Therefore, some people put a mesh protective layer on the outside of multiple tubular membranes, and some people use partitions to divide multiple tubular membranes into several bundles. These methods can play a certain protective role on the tubular membrane, but they are still easy to cause damage to the tubular membrane, and cannot solve the distribution of water flow and the collection of produced water well. They often cause deformation or even damage of the tubular membrane, and the filtration efficiency is low. Especially when the operating pressure and flow rate of the tubular membrane module are large, the problem is more prominent.

In view of the above-mentioned disadvantages of known tubular membrane modules, the inventor of the present invention came up with the idea of creating a novel membrane module. After much discussion and trial production of samples, as well as many revisions and improvements, the present invention was finally launched.

The present invention provides a tubular membrane assembly structure and a packaging method thereof, wherein the tubular membrane assembly structure comprises: a tubular membrane outer shell, the tubular membrane outer shell comprises a membrane shell and two end plates, the membrane shell is provided with a through receiving hole inside, the outer periphery of the membrane shell is provided with at least one filtrate outlet communicating with the receiving hole, the two end plates are assembled and fixed at two ends of the membrane shell, at least one of the two end plates is provided with a plurality of sleeve columns on a side facing the receiving hole, each of the sleeve columns is provided with a flow hole penetrating the end plate; a plurality of tubular membranes , which is in the shape of a circular tube and is arranged in a bundle shape in the receiving hole inside the membrane shell. At least one end of each tubular membrane is inserted and fixed on the sleeve column of the end plate and communicates with the flow hole of the sleeve column. A distance is reserved between each tubular membrane and the end plate; and at least one bonding glue is poured into the receiving hole of the membrane shell near the end plate where the sleeve column is provided, and the height of the bonding glue exceeds the height of the sleeve column, so as to strengthen the bonding strength between each tubular membrane and the end plate and the membrane shell, and make one end of each tubular membrane bonded and fixed to each other. The tubular membrane assembly packaging method comprises the following steps: (a) inserting the tubular membrane step, placing an end plate on a plane, inserting one end of a plurality of tubular membranes in a bundle onto a plurality of sleeve columns provided on one side of the end plate and fixing them, and keeping a distance between the end plate and the tubular membranes; (b) putting on the membrane shell step, sleeve one end of a membrane shell onto the end plate, so that the plurality of tubular membranes are accommodated in a receiving hole provided inside the membrane shell, and the outer periphery of the membrane shell is provided with at least one filtration liquid outlet communicated with the receiving hole; (c) filling the glue step, The filter liquid outlet injects liquid bonding glue into the receiving hole of the membrane shell, and flows to the space between the tubular membranes near the end plate by gravity, and the height of the bonding glue exceeds the height of the sleeve column; (d) waiting for the curing step, waiting for the bonding glue to dry and fix naturally, strengthening the bonding and fixation of one end of each tubular membrane to the end plate and the membrane shell, and making the one ends of each tubular membrane bonded and fixed to each other; (e) assembling the other end plate step, assembling the other end plate on the other end of the membrane shell, bonding and fixing it, and repeating steps (c) and (d).

The main purpose of the tubular membrane assembly structure and the packaging method thereof of the present invention is to strengthen the combination and fixation of the tubular membrane, the membrane shell and the end plate, and to play a certain protective role on the tubular membrane, so as to achieve good water flow distribution and production water collection, avoid deformation of the tubular membrane and even rupture of the inner membrane, and have high filtration efficiency and long service life.

Another purpose of the tubular membrane assembly structure and the packaging method thereof of the present invention is that the packaging method is simple, the packaging is convenient and fast, and the manufacturing cost is reduced.
