Description
Technical Field
[0001] The utility model relates to the technical field of pure water preparation equipment, in particular to an EDI device of pure water preparation equipment. Background Art
[0002] The high residual hardness of the influent water in the EDI device will cause scale to form on the membrane surface of the concentrate channel, resulting in a decrease in concentrate flow and pure water resistivity, affecting the pure water quality. In severe cases, it will block the concentrate and polar water channels of the component, causing the component to be destroyed due to internal heat. In the past, when scale was generated in the EDI device, it needed to be manually scrubbed, which was inefficient. Utility Model Content

The first turbine 3 is fixedly mounted on the bottom plate of the concentrated water area of the EDI device, and the second turbine 4 is located at the end of the concentrated water outlet pipe 5.
[0017] The water spray pipe 1 is installed along the four sides of the upper cover plate 2 of the concentrated water area of the EDI device. The nozzle of the water spray pipe 1 is directed toward the inner wall of the concentrated water area of the EDI device closest to it. The undiluted chemicals can be sprayed directly on the inner wall of the concentrated water area of the EDI device through the water spray pipe 1.
[0018] The concentrated water outlet pipe 5 is connected to the concentrated water area of the EDI device, and the concentrated water outlet pipe 5 is fixedly installed below the outer wall of the concentrated water area of the EDI device.
