Description
BACKGROUND OF THE
In particular, the present invention relates to a telescoping prevention device that can be effectively used in fluid separation and purification techniques using membrane separation devices such as reverse osmosis devices, nano filtration devices, ultrafiltration devices and microfiltration devices.
Recently, due to rapid population growth and environmental pollution, water treatment technology and various projects using the same have been spotlighted as future growth engines.
In particular, the membrane separation device can be used in various fields. The membrane separation device can be used to purify water. For example, seawater may be purified in a membrane separation device that uses reverse osmosis to provide beverages. Also in wastewater treatment, membrane separation devices can be used to disinfect (or sterilize) wastewater by removing polymers, colloids and particles.
The membrane separation device using reverse osmosis can be described as follows.
The two solutions with different concentrations are separated by a semipermeable membrane. After a certain time, a solution with a lower concentration moves toward a higher concentration, causing a constant level difference. This is called an "osmotic" phenomenon. It is called "osmotic pressure". In contrast to the "osmotic" phenomenon, the process of moving a high-concentration solution to a lower concentration by using pressure is called "reverse osmosis." A device that purifies water by passing only the water molecules through the semi-permeable membrane is called a reverse osmosis facility. The semi-permeable membrane entered therein is a "reverse osmosis filter", and such a filter is a "reverse osmosis filter module".
In such a reverse osmosis filter module, a telescoping prevention device (ATD), which is an end cap that prevents stretching / extension (or telescoping) that may be caused by a pressure difference between a water inflow and an outflow. Anti-Telescoping Device) will exist.
The telescoping prevention device functions as an important component in the reverse osmosis filter module because it performs the above-described functions and also serves as an inlet and an outlet of the fluid flowing between the reverse osmosis filter module. The degree of securing the flow path through which the fluid moves is determined.

In addition, by including such a telescoping prevention device to provide a membrane separation device that can perform the purification and separation of the fluid more effectively.
In order to solve the above problems, the apparatus for preventing telescoping for membrane separation apparatus according to the present invention includes a main body portion through which at least two concentric passages are formed, and a plurality of predetermined shapes are formed inside the main body portion. Characterized in that the through-hole is formed.
Preferably, the plurality of through holes may include any one or more of triangular, rectangular, and polygonal shapes.
Preferably, the plurality of through holes may be repeatedly formed.
Preferably, the plurality of through holes has a hexagonal shape, and the plurality of through holes may be formed adjacent to each other.
Preferably, the plurality of through holes may include a honey comb structure.
Preferably, the thickness of the partition wall between the plurality of through holes may be formed to become thicker toward the lower direction.
Preferably, the thickness of the partition wall between the plurality of through holes may be formed to become thinner toward the lower direction.
The telescoping prevention device for membrane separation device according to the present invention includes a main body portion consisting of an inner circumferential ring and an outer circumferential ring, and a plurality of through holes having a predetermined shape are formed between the inner circumferential ring and the outer circumferential ring so that fluid flows. It is characterized in that the configuration.
In addition, the membrane separation device according to the invention is characterized in that it comprises a telescoping prevention device for the membrane separation device.
According to the present invention, by removing the structure of the wing shape used in the prior art, by including at least two concentric passages are formed through the body portion and a plurality of through-holes formed in a constant shape inside the body portion, durability and The passage securing performance will be further improved.
Specifically, since a plurality of through holes are disposed and the structure of the wing shape is excluded, lighter and stronger durability can be achieved for the same size, and it is excellent in securing the flow path, and is complicated in structure because it is not a fastening structure. It has the advantage of not doing it.
