Problems solved by technology

[0005] For the current membrane filtration system, the main problem of the filtration unit is that the sewage is crowded between the narrow filter membrane interlayers, resulting in poor drainage, especially for particulate impurities, which are extremely easy to accumulate between the filter membrane interlayers. It not only seriously erodes the filter membrane, but also causes a large area of ​​filter membrane to be blocked, which seriously weakens the filtration efficiency; in addition, it is necessary to use a large amount of high-speed water body to flush the accumulated impurities sideways, which makes the filter membrane easy to move and damage

Embodiment 1

[0021] figure 1 Shown is the first embodiment of the membrane sewage filtration system, wherein the membrane sewage filtration system includes an outer pipe body 1 and an inner pipe body 2; a tube is formed between the outer pipe body 1 and the inner pipe body 2 type water purification chamber 10; the inside of the inner pipe body 2 is a cylindrical sewage chamber 20; both ends of the water purification chamber 10 are blocked by closing plugs 4; 30; both ends of the sewage chamber 20 are connected to a sewage circulation system with a circulation pump.

[0022] The sewage circulating flow system is mainly composed of a sewage source, such as a sewage tank, and a circulation pipeline. The circulation pipeline connects the sewage source, the inner pipe body 2, and the circulation pump into a circulation loop, so that the sewage circulates continuously in the loop .

[0023] The outer pipe body 1 is made of impermeable material; the inner pipe body 2 is as figure 2 As shown, ...

Embodiment 2

[0028] image 3 Shown is the second embodiment of the membrane sewage filtration system, which is different from the first embodiment in that: the diameter of the nozzle of the inner pipe body 2 near the water inlet end is smaller than the nozzle diameter of the water outlet end, so that the The sewage in the sewage chamber 20 gradually decelerates during the flow process, so that when the fluid just enters the inner pipe body 2, it has greater kinetic energy to drive the hydraulic drive components to rotate, so that the rotation speed of the water body itself is also rapidly increased , so that as soon as the sewage enters the sewage cavity 20, the fine separation of the particles and the water body can be obtained quickly, and the pressure on the surface of the filter membrane along the axial direction of the inner pipe body can be evenly distributed.

Abstract

The invention provides a membrane type sewage filtering system which comprises an outer pipe body and an inner pipe body; a pipe type clean water chamber is defined between the outer pipe body and the inner pipe body; the inner pipe body is internally provided with a column type sewage chamber; two ends of the clean water chamber are sealed by seal stoppers; the clean water chamber is introduced outwards to form a clean water outlet; two ends of the sewage chamber are connected with a sewage circulation flow running system with a circulating pump; the outer pipe body is made from a water impermeable material; the inner pipe body consists of a filtering membrane and a membrane support clamped at two sides of the filtering membrane; the sewage chamber is internally provided with a hydraulic drive part, and the hydraulic drive part rotates around the axes of the inner pipe body under the impact of water body; when the hydraulic drive part rotates, the sewage in the inner pipe body is driven to quickly rotate. When the system is used for filtering the sewage, the amount of particle impurities on the surface of the filtering membrane can be greatly reduced, and the side impact of the water body on the filtering membrane can be reduced; the membrane type sewage filtering system not only is higher in filtering efficiency, but also is not easily damaged.

Description

[0001] technical field [0002] The invention relates to the field of sewage treatment, in particular to a filtration membrane sewage filtration system. [0003] Background technique [0004] In the current sewage filtration system, the use of reverse osmosis membrane for filtration is a commonly used filtration method; for this kind of filtration membrane filtration system, the basic filtration unit used is a filter body made of a filter membrane interlayer; During the process, the sewage flows between the intertwined multi-channel filter membrane interlayers, and enters the interior of the filter membrane interlayers to form clean water. [0005] For the current membrane filtration system, the main problem of the filtration unit is that the sewage is crowded between the narrow filter membrane interlayers, resulting in poor drainage, especially for particulate impurities, which are extremely easy to accumulate between the filter membrane interlayers. Not only severely ero...
