Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric filtering, and in particular relates to a filtering structure containing non-woven fabric. Background Art

[0002] Non-woven fabric filtration is a commonly used filtration method. Its filtration effect mainly depends on the physical effects of the material's pores and friction between fibers, gravity, surface tension, etc. The following are some of the main features and applications of non-woven fabric filtration:

[0003] Filtration principle: The internal structure of non-woven fabrics has a regular distribution of pores, which can effectively isolate most impurities such as suspended matter and solid particles. When liquid or gas passes through the non-woven fabric, the impurities will be trapped in the fiber gaps of the non-woven fabric, thus achieving the purpose of filtration.

[0004] Factors affecting filtration accuracy: The filtration accuracy of non-woven fabrics is affected by many factors, including fiber thickness, yarn density, thickness of non-woven fabrics, etc. Generally speaking, the finer the fiber, the greater the yarn density, and the thicker the non-woven fabric, the higher the filtration accuracy.

[0005] Application fields: Non-woven fabric filtration is widely used in various industries, medical treatment, environmental protection and other fields. For example, in industrial production, non-woven fabric filtration can be used for liquid filtration, air filtration, etc.; in the medical field, non-woven fabric filtration can be used to make masks, surgical gowns, etc.; in the environmental protection field, non-woven fabric filtration can be used for sewage treatment, air purification, etc.

[0006] It should be noted that although non-woven fabric filtration has many advantages, it also has some limitations. For example, the filtration accuracy and filtration efficiency of non-woven fabrics are limited by their materials and processes, and cannot fully meet the needs of certain high-precision filtration. In addition, non-woven fabric filtration also has certain resistance, which will increase the energy consumption and operating costs of the filtration system.

[0007] Non-woven fabric filters may encounter clogging and reduced lifespan during use, which is usually related to a variety of factors. The following are some possible causes of clogging and reduced lifespan of non-woven fabric filters and their corresponding solutions:

[0008] Excessive residue:

[0009] Reason: Non-woven filter materials that have been used for too long may have a large amount of filter cake or particles remaining on the surface, causing pore blockage and reduced water permeability.

[0010] Solution: Regularly check and clean the non-woven filter material to remove residues in time and restore its filtering performance. If the blockage is serious, it may be necessary to replace the non-woven filter material with a new one.

[0011] Nonwoven quality:

[0012] Reason: Some non-woven filter materials may have quality problems, such as low density, small and dense pore size, etc., which may lead to strong particle retention ability, but easy clogging, and poor anti-clogging and cake removal effects.

[0013] Solution: Choose high-quality non-woven filter materials that are suitable for specific application scenarios. When selecting, factors such as the material's water permeability, anti-clogging and cake-removal properties should be fully considered.

[0014] Improper use of flocculants or filter aids:

[0015] Reason: Under working conditions where flocculants or filter aids need to be added, if the dosage is too large or too small, the slurry viscosity may be too high, thus affecting the filtration effect and making the non-woven filter material more easily clogged.

[0016] Solution: According to the specific process requirements, reasonably control the dosage of flocculant or filter aid to ensure the slurry viscosity is moderate, so as to improve the filtration effect and extend the service life of the non-woven filter material.

[0017] Improper operation:

[0018] Cause: During operation, if the pressure is too high, the flow rate is too fast or the operation is not standardized, the non-woven filter material may be damaged or blocked.

[0019] Solution: Strictly follow the operating procedures, control the appropriate pressure and flow rate, and avoid excessive impact and wear of the non-woven filter material. At the same time, regularly train operators to improve their operating skills and quality.

[0020] Environmental factors:

[0021] Reason: Environmental factors such as temperature, humidity, pH, etc. may also affect the performance of non-woven filter materials, causing them to become clogged or their lifespan to be reduced.

[0022] Solution: When using non-woven filter materials, you should pay attention to changes in environmental conditions and take appropriate measures to protect them. For example, in high temperature or high humidity environments, protective measures can be used to reduce damage to non-woven filter materials. Utility Model Content
