Description

A detection device for efficiently disassembling and assembling reverse osmosis membrane Technical Field

[0001] The present invention relates to the technical field of reverse osmosis membrane detection devices, in particular to a detection device for efficiently disassembling and assembling a reverse osmosis membrane. Background Art

[0002] The feed water source for boilers in power plants is generally recycled wastewater that has been softened with lime. Due to the high concentration ratio of the recycled water, the salt content of the wastewater is high. Traditional ion exchange desalination processes can no longer meet current water treatment requirements. Currently, reverse osmosis is the mainstream desalination process for boiler feed water in power plants. The core of the reverse osmosis device is the reverse osmosis membrane element. During daily operation and maintenance, if the conductivity is found to be too high, the membrane needs to be removed for testing. Due to the adsorption of water on the reverse osmosis membrane and the friction between the internal rubber seal and the internal membrane shell, the membrane removal operation greatly increases the labor intensity of maintenance personnel. Moreover, improper operation and excessive force during the removal process can cause irreversible damage to the reverse osmosis membrane, seriously affecting the normal use of the reverse osmosis device.
