Embodiment 1

[0030] Embodiment 1 (manufacturing 100 square meters of needle felts)

[0031] The intermediate chemical fiber base cloth layer is made of PTFE fiber, the specification is 150g / m 2 .

[0032] The face yarn is made of ultra-fine E-glass fiber and ultra-fine PTFE fiber. Among them, the amount of E glass fiber accounts for 70%, and PTFE accounts for 30%. The dosage is 42Kg and 18Kg respectively. The face layer yarn is made by conventional production process. Its specification is 600g / m 2 .

[0033] The inner layer yarn is made of E glass fiber and PTEF ordinary chemical fiber material, and its specifications are 5-7um and 10um respectively. PTEF chemical fiber accounts for 70%, E glass fiber accounts for 30%. Made into inner yarn. Its specification is 600g / m 2 . Then use the conventional needle punching process to make the surface layer yarn, the inner layer yarn and the intermediate chemical fiber base cloth into a plain felt. The finished plain felt is then chemicall...

Embodiment 2

[0035] The intermediate chemical fiber base cloth layer is made of PTFE fiber, the specification is 150g / m 2 .

[0036] The surface yarn is made of ultra-fine E glass fiber, and its specification is 600g / m 2 .

[0037] The inner yarn is made of E glass fiber and chemical fiber material, PTEF chemical fiber accounts for 70%, E glass fiber accounts for 30%. The two fiber specifications are 7um and 10um respectively. Made into inner yarn. Its specification is 600 / m 2 . , and then use the conventional acupuncture process to make plain felt. The finished plain felt is then chemically treated. The compounding method of chemical treatment agent is identical with embodiment 1. Then dry it. Hot press calendering treatment. Process is identical with embodiment 1.

Abstract

The invention relates to a high-efficient needle punched filter felt for purifying Pm 2.5 fine particles and a manufacturing method thereof, relating to a high-efficient needle punched filter felt for purifying Pm 2.5 fine particles in industrial smoke gas and a manufacturing method thereof. The product is used for iron and steel, smelting, carbon black, cement and waste incineration, and belongs to industrial environmentally-friendly filtering material. A needle punched filter felt is composed of surface layer yarn, inner layer yarn and middle chemical fiber base cloth; the surface layer yarn of the needle punched filter felt is made of superfine fiber; and the inner layer yarn is made of large diameter ordinary fiber. The method is simple and easy to implement; the dedusting efficiency of the needle punched filter felt manufactured by the invention can reach 99.99%, and Pm 2.5 fine particles dust can be efficiently purified. The materials of the surface layer yarn and the inner layer yarn are reasonably matched, and are used according to different characteristics and features of microfiber, coarse fiber, glass fiber and chemical fiber. The effect of filtering smoke gas is improved, and the service life of a filter bag is also prolonged. The production and use costs are greatly reduced. The problem existing in the existing filtering material is solved.

Description

technical field [0001] The invention relates to a high-efficiency acupuncture filter for purifying industrial flue gas Pm2.5 fine particles and a manufacturing method thereof. The products are used in the purification of industrial flue gas such as steel, smelting, carbon black, cement, waste incineration, coal-fired boilers in power plants, etc., and belong to industrial environmental protection filter materials. Background technique [0002] Relevant information is available: At present, about 66.7% of cities in my country have excessive concentrations of atmospheric particulate matter. For example, Beijing, which has better air quality, has an annual average concentration of Pm2.5 in the atmosphere of 104.9ug / m 3 , is the US recommended standard 2.5ug / m 3 Shenyang emits about 80,000 tons of Pm10 into the atmosphere every year, of which the particles below Pm3 are about 36-52% of Pm10. More than 110 kinds of organic compounds such as polycyclic aromatic hydrocarbons (PQH...
