Embodiment Construction
[0013] The reverse osmosis device shares a set of online cleaning system, and each cleaning can only realize the online cleaning of one set of reverse osmosis membrane components.
[0014] 1. Reverse osmosis cleaning water pump model IH100-65-200, flow rate 120m 3 / h, lift 47 m. A return line is set at the outlet of the pump to facilitate the stirring of the agent and the adjustment of the concentration of the cleaning solution.
[0015] 2. Clean the filter GBAN-600 with a flow rate of 100 m 3 / h. A rotameter is installed at the outlet of the cleaning filter to judge whether the flux of the reverse osmosis membrane returns to normal during the cleaning process.
[0016] 3. Cleaning water tank 4 m 3 , The water temperature control mainly adopts the condensate of the compressor unit in the factory area, and the water temperature is about 40 ℃ and piped to the cleaning water tank. The upper part of the cleaning water tank body is provided with a dispensing hole, and the lowe...

The invention belongs to the field of reverse osmosis device film component cleaning, in particular to a reverse osmosis online cleaning device, which is suitable for multiple sets of parallel reverseosmosis online cleaning. The reverse osmosis on-line cleaning device comprises a cleaning water pump, a cleaning water tank and a cleaning filter, wherein the cleaning water pump is respectively connected with the cleaning water tank and the cleaning filter through cleaning pipelines; the cleaning filter is respectively connected with water inlet pipelines of a first-stage reverse osmosis film component and a second-stage reverse osmosis film component through the cleaning pipelines; concentrated water outlet pipelines of the first-stage reverse osmosis film component, the concentrated wateroutlet pipelines of the second-stage reverse osmosis film component and water production pipelines of the reverse osmosis film component are all connected to the cleaning water tank through the cleaning pipelines; gate valves are arranged on the cleaning pipelines. The reverse osmosis online cleaning process of the device is divided into three steps of sterilization, alkali cleaning and acid cleaning. According to the invention, online cleaning is realized through transformation, the operation difficulty and the cleaning time are reduced, and the situation that desalted aquatic product water supply is tight due to cleaning of the reverse osmosis film is avoided.
Description
technical field [0001] The invention belongs to the field of membrane module cleaning of reverse osmosis devices, in particular to a reverse osmosis online cleaning device, which is suitable for multiple sets of parallel reverse osmosis online cleaning. Background technique [0002] The desalinated water device generally adopts a reverse osmosis device, which adopts one-stage reverse osmosis treatment and is equipped with a concentrated brine reverse osmosis recycling device. Membrane components. The reverse osmosis unit mainly produces half desalted water. When reverse osmosis is performing semi-desalination treatment, most of the salts are trapped when the ions that make up the salt pass through the reverse osmosis membrane module, and will gradually concentrate on the surface of the membrane module, and the highly concentrated water will form scaling and some microorganisms It will breed in the membrane and cause the blockage of the reverse osmosis membrane module. The ...
