Problems solved by technology

The disadvantage of such a membrane filtration system is that only one row of membrane elements can be installed, and only internal pressure membranes can be used, the filtration efficiency is relatively low, and the applicability is limited to a certain extent. Bypass water distribution pipe, water main pipe, membrane filament and membrane shell wrapped outside the membrane filament, so the structure is more complicated and the cost is relatively high

specific Embodiment 1

[0036] For a horizontal press immersion composite membrane filtration system of the present invention, please refer to Figure 4 to Figure 12 , comprising a pressure vessel 1 with closed ends and at least one row of membrane element assemblies enclosed in said pressure vessel 1, each row of membrane element assemblies is provided with at least two membrane elements 2 arranged in series, and said membrane element assemblies are connected to said membrane element assemblies There is a gap 18 between the pressure vessels 1, the two ends of each row of membrane element assemblies are inserted on the end plate 6, and the two adjacent membrane elements 2 in each row are sealed and connected by a connecting piece 7 , the two end plates 6 separate the inner space of the pressure vessel 1 into end chambers 8 at both ends and an intermediate chamber 9 between the two end chambers 8, and the membrane element 2 includes an inner membrane filament 10 And the outer net 11 wrapped on the out...

specific Embodiment 2

[0042] For a horizontal press immersion composite membrane filtration system of the present invention, please refer to Figure 4 to Figure 12 , on the basis of the first embodiment, the pressure vessel 1 is provided with two middle water inlets and outlets 14 outside the intermediate chamber 9, and the two middle water inlets and outlets 14 are located at the two ends of the intermediate chamber 9 . Of course, more water inlets and outlets 14 in the middle can also be set. It is preferable to set two water inlet and outlet ports 14 in the middle, because in this way, normal washing can be carried out in the cleaning stage, and one is a clean water inlet, and the other is a concentrated water discharge port discharged as high-concentration pollutant water. The two middle water inlets and outlets 14 are respectively located at the end of the middle chamber 9. The advantage is that the water intake is large, and at the same time, the membrane elements 2 at both ends are taken in...

specific Embodiment 3

[0043] For a horizontal press immersion composite membrane filtration system of the present invention, please refer to Figure 4 to Figure 12 , on the basis of the specific embodiment 1 and the specific embodiment 2, the membrane element 2 may also include a sealing head 15 located at both ends of the membrane filament 10 and an end 16 located outside the sealing head 15, the sealing The head 15 is arranged at the end of the membrane filament 10 , and the end 16 fixes the sealing head 15 , the membrane filament 10 and the outer net 11 together. In this way, the sealing head 15 fixes each membrane filament 10, and the head end of each membrane filament 10 is in contact with the outside world, and the function of the end head 16 is to fix the sealing head 15 and the outer net 11 together to form a water-permeable membrane. The membrane element 2. Only such a membrane element 2 can be applied to both internal pressure infiltration and external pressure infiltration, which expand...

Abstract

The invention discloses a horizontal pressure leaching composite membrane filtering system, comprising a sealed pressure container and at least one row of membrane element assemblies which are arranged in the pressure container, wherein each row of the membrane element assemblies comprises at least two serial connected membrane elements. A gap is formed between the membrane element assembly and the pressure container. The two ends of the membrane element assembly are inserted on an end plate, and the two adjacent membrane elements are connected through a connection piece. The inner space of the pressure container is divided into an end cavity and a middle cavity through the two end plates. The membrane element comprises an inner membrane wire and an outer net which is covered on the external part of the membrane wire, and water flows inside or outside from the outer net. The membrane element is provided with a water pipe which passes through the front end and the rear end of the membrane element. The pressure container is provided with a water inlet and water outlet of the end part, and further provided with the water inlet and the water outlet of the middle part. The horizontal pressure leaching composite membrane filtering system of the invention has a simple structure, filters at the same time through multiple membrane elements, effectively improves the filtering efficiencyof the filtering system, easily changes the parts and maintain, has multiple operation methods, and greatly improves the applicability.

Description

technical field [0001] The invention relates to a membrane filtration system, in particular to a horizontal pressure immersion composite membrane filtration system. Background technique [0002] The existing horizontal membrane filtration system is generally composed of a pressure vessel 1 , a hollow fiber membrane element 2 with a casing, an insert joint 3 and an end cover 4 . A row of 4 membrane elements with shells are installed in series in each pressure vessel, the membrane elements are connected by inserting joints, and both ends of the pressure vessel are sealed by end caps. [0003] Existing horizontal membrane systems are generally only equipped with internal pressure membrane elements, and the section and profile of a single membrane element are as follows: figure 2 and image 3 As shown, the membrane element 2 is provided with a water production collecting pipe, a bypass water distribution pipe, a water production main pipe, a membrane filament and a membrane ca...
