Background
The reverse osmosis technology is widely applied to advanced treatment and recycling of sewage and wastewater, can obtain high-quality reclaimed water, provides an important water source for industrial production, and realizes good environmental benefit. The reverse osmosis membrane elements are 8040, 4040, with the first 80 or 40 representing the membrane element diameter of 8 inches or 4 inches and the second 40 representing the membrane element length of 40 inches. The reverse osmosis membrane element is usually placed in a pressure vessel (membrane shell) of a corresponding size, and forms a membrane module with the membrane shell. According to the different number of reverse osmosis membrane elements connected in series in the membrane shell, the specification of the membrane shell is different from 1 core to 7 cores. The 8040 type reverse osmosis membrane element is the most commonly used in industry, and generally has a length of about 101cm, and the inner diameter of the central water production pipe is about 3cm.
Membrane fouling is an inevitable problem during the operation of reverse osmosis systems. The pollution of the reverse osmosis membrane element not only affects the quality and the quantity of produced water, but also can cause the pressure difference to rise, the operating pressure and the energy consumption to be increased, and the economical efficiency and the safety of the operation of the reverse osmosis system are directly reduced. If necessary, the reverse osmosis membrane element needs to be taken out of the pressure vessel, subjected to membrane fouling, membrane element appearance inspection, or subjected to off-line cleaning. The traditional membrane unloading method only has a few persons to push the membrane element out of the membrane shell by using the resultant force of the stainless steel tube with the circular baffle plate, and another person removes the membrane element exposed from the membrane shell at the other end of the membrane shell. The removal of reverse osmosis membrane elements from pressure vessels often presents the following hazards or difficulties: (1) The end cover of the pressure vessel (membrane shell) is difficult to detach, and the end cover is easy to damage in the detaching process, so that the Chinese patent with the publication number of CN213532434U provides a reverse osmosis membrane detaching tool; meanwhile, the Chinese patent with the issued publication number of CN217751229U provides a reverse osmosis membrane dismounting device, and the tool or the device can be used for safely and effectively dismounting the end cover of the membrane shell; (2) After the end covers of the membrane shell are disassembled, a plurality of reverse osmosis membrane elements connected in series are taken out of the membrane shell, and a certain distance is reserved between the reverse osmosis membrane elements and two ends of the membrane shell, so that the disassembly or the forced application is inconvenient; (3) The reverse osmosis system has limited surrounding space, which is not beneficial to accommodating multiple people or other equipment with mechanical auxiliary force and is also not beneficial to the operation and use of tools with longer length; (4) The brand and model of the reverse osmosis membrane element are different, the section structure of the membrane element is different, and some disassembly tools are not applicable; (5) When the reverse osmosis membrane element is detached from the membrane shell, if the operation is improper or the tool is defective, the end face structure of the membrane element is damaged, and meanwhile, the reverse osmosis membrane element is easy to fall to the ground to be damaged after coming out of the membrane shell.
At present, a certain defect exists in the disassembly tools of the reverse osmosis membrane elements. If the patent is issued in China with the publication number of CN210389039U, a tool for disassembling a reverse osmosis membrane element is disclosed, the tool is mainly applied to a special tool for disassembling a third reverse osmosis membrane element and a fourth reverse osmosis membrane element of a reverse osmosis system with more than six membrane elements in a membrane shell, a fixed clamp and a movable clamp are adopted to clamp members on the end face of the reverse osmosis membrane, the reverse osmosis membrane is pulled out, the end face of the reverse osmosis membrane is easily damaged, and two forces of pulling force and pressing force of hands of an operator are needed, the operation difficulty is high, and if the reverse osmosis membrane element slips from between the fixed clamp and the movable clamp, the falling injury of the operator is easily caused; the Chinese patent with the publication number of CN217345297U discloses a reverse osmosis membrane dismounting tool, which can reduce the damage possibility in the reverse osmosis membrane dismounting process, but has complex structure, has the structures of a traction mechanism, a base, a telescopic rod, a membrane receiving disc, a balancing weight and the like, has large occupied area, is inconvenient to move and is not suitable for a narrow space.
