Embodiment 1

[0036] A mixture of 30% sulfonamide fiber and 70% glass fiber is used as the fiber of the high temperature resistant non-dust-facing layer and the supporting layer of the dust-facing layer. First put the sulfonamide fiber and glass fiber into the opener for uniform mixing and opening, and then comb it into a uniform fiber web on the carding machine according to the design weight. The above mixed fiber web is transformed into two cross-laminated Multi-layer fiber layer, in which the non-dust layer side is about 200gsm, the dust layer support layer is about 100gsm, with 420gsm of 100% alkali-free glass fiber, the base cloth with a density of (120*80) / 10cm, and the above-mentioned mixed fiber net Carry out composite pre-acupuncture reinforcement, and then card and process the aramid fiber layer with a grammage of 100gsm as the reinforcing fiber of the dust-facing layer, and perform pre-acupuncture reinforcement. The above pre-acupuncture reinforced fiber structure is jointly fed ...

Embodiment 2

[0038] A mixture of 30% polysulfone fiber and 70% non-alkali glass fiber is used as the fiber of the high temperature resistant non-dust layer and the support layer of the dust layer. First put the sulfonamide fiber and alkali-free glass fiber into the opener for uniform mixing and opening, then comb it into a uniform fiber web on the carding machine according to the design weight, and convert the above mixed fiber web into two crossed fiber webs through cross winding equipment. Laminated multi-layer fiber layers, in which the non-dust-facing layer is about 200gsm, the dust-facing layer support layer is about 100gsm, 420gsm of 100% alkali-free glass fiber, the density is (120*80) / 10cm base cloth, mixed with the above The fiber web is reinforced by composite pre-acupuncture, and then carded and processed with a sulfonamide fiber layer of 100gsm as the reinforcing fiber for the dust-facing layer, which is then pre-acupuncture reinforced. The above pre-acupuncture reinforced fibe...

Abstract

The invention relates to a high temperature resistant filter material, a device containing the high temperature resistant filter material and a manufacturing method of the product. The invention relates to a high-temperature resistant filter material, which is formed by compounding of four layers in order: a dust receiving layer A, a dust receiving layer B, a reinforcing fabric, and a non-dust receiving layer. The dust receiving layer A is made of 100% organic high temperature resistant fiber and has a gram weight of 100gsm, the dust receiving layer B and the non-dust receiving layer are both composed of organic high temperature resistant fiber and inorganic high temperature resistant fiber. The reinforcing fabric is made of organic high temperature resistant fiber. The dust receiving layer B has an organic high temperature resistant fiber content of 30wt%, an inorganic high temperature resistant fiber content of 70wt%, and a gram weight of 80-120gsm. The non-dust receiving layer has an organic high temperature resistant fiber content of 30wt%, an inorganic high temperature resistant fiber content of 70wt%, and a gram weight of 300gsm. Through research on product structure, component proportion and processing technology, a new product plan is optimized and designed, and the product can acquire more excellent use performance.

Description

technical field [0001] The invention relates to a high-temperature-resistant filter material, a device containing the high-temperature-resistant filter material and a manufacturing method of the above-mentioned product. Background technique [0002] In the industrial production process of iron and steel, cement, etc., each process will produce a large amount of smoke gas, which includes CO2, SO2, nitrogen oxides, various metal compounds, a small amount of raw materials carried out by the air flow, and various combustion gases. Dust particles and other substances, if these substances are directly discharged into the atmosphere, on the one hand, they will cause pollution to the natural environment, affect the lives of residents around the factory and even cause diseases and ecological problems; Dust is also not conducive to cost control in industrial production. In the current environment where environmental protection requirements are getting higher and higher, in order to a...
