TECHNICAL FIELD
[0001] The utility model relates to a kind of dismounting tools, specifically a kind of full-automatic reverse osmosis membrane element dismounting tool. BACKGROUND
[0002] Reverse osmosis membrane is a kind of artificial semi-permeable membrane with certain characteristics, which is made of simulating biological semi-permeable membrane, and is the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate water from other substances under the action of higher solution osmotic pressure. The membrane pore size of reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms and organic matter in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation.
[0003] Reverse osmosis membrane is the core element of reverse osmosis, which is a kind of artificial semi-permeable membrane with certain characteristics, made of simulating biological semi-permeable membrane. It is usually made of high molecular materials, such as cellulose acetate membrane, aromatic polyhydrazide membrane and aromatic polyamide membrane. The diameter of surface micropore is generally between 0.5-10 nm, and the size of permeability is related to the chemical structure of the membrane itself. Some high molecular materials have good salt rejection, but the water permeation speed is not good. Some high molecular materials have more hydrophilic groups in their chemical structure, so the water permeation speed is relatively fast. Therefore, a satisfactory reverse osmosis membrane should have appropriate permeation amount or desalination rate. Reverse osmosis membrane should have the following characteristics: (1) high desalination rate at high flow rate; (2) high mechanical strength and service life; (3) function under low operating pressure; (4) resistant to chemical or biochemical effects; (5) less affected by pH value, temperature and other factors; (6) easy to obtain raw materials for membrane preparation, simple to process and low in cost.
[0004] Reverse osmosis membrane needs regular maintenance and replacement. Since reverse osmosis membrane is installed in membrane shell, both ends are sealed with end cover, and end cover is composed of center tube, thrust ring, sealing plate, O-shaped sealing ring, pressure bearing plate, plug, clasp ring, locking nut, etc. In order to remove reverse osmosis membrane element from membrane shell, jacket or high pressure flushing method is usually used to remove reverse osmosis membrane element, which may cause damage to reverse osmosis membrane element.
