Description

Technical Field

[0001] The utility model belongs to the technical field of filter cloths, and more specifically, particularly relates to a low-resistance and high-efficiency modified PPS high-temperature smoke filter cloth. Background Art

[0002] The needle-punched felt in the existing technology is mainly used as a filter material. The glass fiber needle-punched felt is formed by combing short chopped fiber into cotton and then needle-punching it on a glass fiber base cloth. In terms of high-temperature flue gas filtration, it cannot adapt to working under harsh working conditions. With the enhancement of people's environmental awareness, the application scope of needle-punched felt is constantly expanding. The fields of high-temperature dust removal, purification, heat insulation, and thermal insulation have higher and higher requirements on the temperature resistance, chemical stability, corrosion resistance, adsorption and other properties of existing needle-punched felt, including polyester fiber needle-punched felt.

[0003] Based on the above, the inventors have found the following problems: the current high-temperature flue gas filter cloth may absorb a large amount of dust or impurities on the surface of the filter cloth under the influence of static electricity during use, which may cause trouble to the staff, and the wear resistance is generally low, and a variety of cleaning or maintenance methods cannot be used, which indirectly reduces the efficiency of the use of the filter cloth.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a low-resistance and high-efficiency modified PPS high-temperature flue gas filter cloth is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effect of the low-resistance and high-efficiency modified PPS high-temperature flue gas filter cloth of the utility model are achieved by the following specific technical means:

[0006] A low-resistance, high-efficiency modified PPS high-temperature flue gas filter cloth comprises a filter cloth body, wherein the filter cloth body comprises a support layer, a pre-filter layer, a main filter layer, an anti-scaling layer, and a reinforcement layer. The pre-filter layer is installed at the bottom end of the support layer, the main filter layer is installed at the bottom end of the pre-filter layer, the anti-scaling layer is installed at the bottom end of the main filter layer, and the reinforcement layer is installed at the bottom end of the anti-scaling layer.

[0007] Furthermore, the material of the support layer includes metal fiber and nylon fiber.

[0008] Furthermore, the metal fibers and nylon fibers are cross-woven in a spiral shape.

[0009] Furthermore, the material of the pre-filter layer is set to be polyester fiber.

[0010] Furthermore, the material of the main filter layer is set to polystyrene fiber.

[0011] Furthermore, the material of the anti-scaling layer is set to be polytetrafluoroethylene.

[0012] Furthermore, the reinforcement layer is configured as an aramid mesh.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the design of metal fiber and nylon fiber, the metal fiber has good mechanical strength and corrosion resistance, while the nylon fiber has excellent toughness and wear resistance. The cross-weaving of the two can effectively improve the structural strength and durability of the filter cloth. At the same time, the conductive property of the metal fiber can resist the influence of static electricity and maintain good filtration efficiency in high temperature and high humidity environments. The softness and elasticity of the nylon fiber make the supporting layer easier to deform, thereby reducing the pressure drop of the filter cloth, which can effectively improve the use efficiency of the filter cloth.

[0015] Through the design of polyester fiber, it can maintain good physical and chemical stability in high temperature and high humidity environments, and will not degrade due to the influence of chemical substances. At the same time, polyester fiber also has good heat resistance and can maintain good performance at high temperatures. The surface of polyester fiber is smooth and dust and particles are not easily attached during cleaning. It can be cleaned and maintained by water washing or mechanical vibration, thereby extending the service life of the filter cloth.

[0016] Through the design of polystyrene fiber, the filter cloth can have high tensile strength and good mechanical strength. It is not easy to break or deform during use. At the same time, it has good flexibility and can adapt to the deformation of the filter system to ensure the filtering effect.

[0017] Through the design of polytetrafluoroethylene, the filter cloth can have excellent non-stickiness, which can effectively resist the adhesion of dust particles and pollutants in the flue gas, thereby avoiding the occurrence of problems such as scaling and clogging.

[0018] Through the design of the aramid mesh, the filter cloth can have good air permeability, will not hinder the flow of smoke, and ensure the filtering efficiency and ventilation performance. BRIEF DESCRIPTION OF THE DRAWINGS
