Problems solved by technology

[0013] Therefore, even if the state change of each membrane element can be confirmed, the method of maintenance is different depending on the cause of the change, so if the cause cannot be identified, the maintenance cannot be performed satisfactorily.
In addition, in the case of erroneous identification of the above-mentioned reasons, even if maintenance is performed, not only cannot obtain good results, but may cause problems such as shortening the life of each membrane element.

no. 1 approach

[0045] figure 1 It is a schematic cross-sectional view showing an example of a spiral membrane filtration device 50 including the spiral membrane element 10 according to the first embodiment of the present invention. also, figure 2 yes means figure 1 A perspective view of the internal structure of the spiral membrane element 10. This spiral membrane filtration device 50 (hereinafter simply referred to as “membrane filtration device 50 ”) is configured by arranging a plurality of spiral membrane elements (hereinafter simply referred to as “membrane elements 10 ”) on a straight line in the outer cylinder 40 .

[0046] The outer cylinder 40 is a resin cylinder called a pressure vessel, and is formed of, for example, FRP (Fiberglass Reinforced Plastics). One end of the outer cylinder 40 is formed with a raw water inlet 48 through which raw water (stock solution) such as drainage and sea water flows in, and the raw water flowing in from the raw water inlet 48 is filtered by a p...

no. 2 approach

[0066] In the first embodiment, a configuration in which power generation is performed based on the rotation of the rotating body (impeller 21 ) provided in the center pipe 20 has been described. In contrast, the second embodiment is different in that a rotating body is provided in the raw water flow path formed by the supply-side flow path member 18 .

[0067] Figure 5 It is a schematic perspective view showing an example of the internal structure of the spiral membrane element 10 according to the second embodiment of the present invention, and shows a state in which the internal structure is seen through. In this example, the membrane member 16 wound around the central tube 20 is divided into two along the axial direction of the central tube 20 , and a space 27 is formed between the end surfaces of the divided membrane members 16 . This space 27 is a region where raw water flows from the raw water flow path 28 formed by the supply-side flow path member 18 in one of the div...

no. 3 approach

[0073] In the second embodiment, a structure in which power generation is performed based on the rotation of a rotating body (impeller 121 ) provided at the center of the membrane element 10 has been described. On the contrary, the third embodiment is different in that a rotating body is provided at the end of the membrane element 10 .

[0074] Figure 6 It is a schematic perspective view showing an example of the internal structure of the spiral membrane element 10 according to the third embodiment of the present invention, and shows a state in which the internal structure is seen through. In this example, a seal carrier for holding a seal member (not shown) on the outer peripheral surface of the membrane element 16 wound around the central tube 20 in the axial direction, or a device for preventing the expansion and contraction deformation of the membrane member 16 is attached. The anti-telescopic part functions as the end part 11 . The raw water flowing in the raw water ch...

Abstract

Provided are a spiral film element capable of securing more electric power without any complicated work, a spiral film-filtration device having the element, and a film-filtration device managing system and a film-filtration device managing method using the device. The spiral film-filtration device comprises a sensor (such as a flow rate sensor (32)) for detecting the properties of a liquid, a power-generating unit (such as a coil (25)) for generating an electric power with the liquid, and a radio-transmission unit (a communication unit (36)) supplied with the electric power from the power-generating unit for radio-transmitting a detected signal from the sensor. As a result, the power-generating unit generates the electric power by using the liquid (such as raw water, filtered water or condensed water) detected by the sensor, so that more electric power can be secured without any complicated work. The electric power from the power-generating unit is supplied to at least the radio-transmission unit, and the detected signal of the sensor is radio-transmitted from the radio-transmission unit.
