Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a flexible flat membrane water collection channel device with a double-row staggered sequence structure. Background Art

[0002] With the continuous improvement of sewage treatment requirements, more and more projects need to be upgraded, especially domestic sewage. As urbanization becomes more mature, more and more communities, schools, and rural areas need to treat domestic wastewater. In the upgrading and transformation, membrane treatment technology is often our hot choice.

[0003] MBR membranes are divided into two categories according to their structure: hollow fiber membranes and flat membranes. As a high-efficiency, low-pollution purification technology that integrates separation and concentration, flat membrane separation technology has the characteristics of simple operation, convenient maintenance, low energy consumption, and strong adaptability. It has been widely used in sewage treatment in related industries. However, due to the special structure of flat membranes, their filling area per unit space is lower than that of hollow fiber membranes, which is one of the main reasons why flat membranes are limited in actual operation.

[0022] In the figure: 1-1 water collection port; 1-2 water outlet; 1-3 fixed end; 1-4 main channel pipe. DETAILED DESCRIPTION

[0023] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] Combine the following Figure 1 and Figure 2 The specific implementation modes of the present utility model are described in detail.

[0025] The specific steps are as follows:

[0026] 1. Prepare two flexible flat membrane water collection channel devices with double-row staggered structure and several water outlet membrane elements on the same side at the upper and lower ends.

[0027] The outer diameter of the water outlet of the membrane element water collection support is 10mm, the thickness of the water collection support is 12mm, and the width of the water collection support is 35mm.

[0028] The main channel pipe of the device 1-4 is about 600mm long and 68mm in outer diameter, with a total of 56 1-1 water collection ports arranged; the water outlet is about 45mm long, the 1-2 water outlet has an outer diameter of 63mm, and can be connected to standard DN50 plastic pipe fittings; the 1-3 fixed end is about 55mm long and 18mm thick.

[0029] The device 1-1 water collection port is in the shape of an 8, with a center distance of 12mm between the top and bottom of each water collection port, a maximum outer diameter of 15mm, and an inner diameter of 10mm. The center distance between adjacent 1-1 water collection ports in the same row is 25mm, the center distance between adjacent 1-1 water collection ports in the upper and lower rows is 12.5mm, and the shortest vertical distance between the outer diameters of the upper and lower water collection ports is about 5mm.

[0030] For specific structural forms, see Figure 1 .

[0031] 2. Fix the two devices 1 up and down on the matching tooling. The vertical height of the two devices can be determined according to the actual length of the membrane element used. The two devices are placed in the same direction and are parallel to form a rectangle.

[0032] The water outlet of the water outlet membrane element water collecting support member on the same side of the upper and lower ends is connected to the center of the water collecting port of the device 1-1 fixed above and below by socket sealing.

[0033] Specifically, the water collecting port 1-1 of the device is connected to the membrane element in an alternating and staggered order, that is, if the upper water outlet of the membrane element is assembled with the 1-A row of water collecting ports of the upper device 1-1, the lower water outlet is assembled with the 2-A row of water collecting ports of the lower device 1-1, and similarly, the 1-B and 2-B rows are connected in a one-to-one corresponding socket manner in a horizontal order.

[0034] For specific installation methods, see Figure 2 .

[0035] 3. After installation, the distance between adjacent membrane elements in the upper and lower rows is about 12mm, the vertical distance in the width direction of the water collection support is about 8mm, the horizontal distance in the thickness of the water collection support is about 3mm, and the horizontal distance between the water collection supports of adjacent water collection ports in the same row is 12mm. If the adjacent membrane elements are installed in a staggered order, there will be no impact between the water collection supports when loading and unloading the membrane elements, which meets the use requirements.

[0036] 4. If the water collection ports of the device 1 are in a single row and the main pipeline is of the same length, and the outer diameters of adjacent water collection ports are tangent without considering the difficulty of the manufacturing process, a maximum of 40 water collection ports can be arranged, which is at least 30% lower than the structural packing density of the device 1; when installing and disassembling membrane elements, the small gap between the water collection supports in the same row affects the operating line of sight and operating space, thereby reducing efficiency.

[0037] It should be noted that, in this article, the term "includes", "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or system including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or system. In the absence of more restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or system including the element.
