背景技术Background technique
除尘技术的主要目标是控制烟气颗粒物排放、减少大气污染。在各种燃煤设备中，燃煤锅炉设备占将近80％，因此燃煤锅炉烟气治理是减少污染的关键。针对以上问题，主要采取的有湿法除尘、电除尘、袋式除尘三种方法，其中袋式除尘器在除尘效率可达99％、使用费用、设备要求和性能等方面均优于湿法除尘和电除尘，将逐渐取代后两者而占据主流工业除尘器市场，而过滤材料时除尘器的关键，过滤材料的性能决定除尘器的优劣，因此要求滤料具有良好耐高温性能。随着科技的飞速发展，电力、钢铁、建筑等工业的不断崛起，在给人们创造了更加富裕、方便、快捷的生活的同时，也对我国的能源、环境的可持续发展造成了严重的威胁。这些社会工业排放的大气污染物中，主要是工业用炉和垃圾焚烧排放的高温烟气和粉尘等腐蚀性化学物，如果不经过治理而直接排入大气中，会直接或间接影响到人们的呼吸系统、心血管系统、中枢神经系统、免疫系统等，并进而威胁到人体的生命安全。The main goal of dust removal technology is to control the emission of flue gas particles and reduce air pollution. Among all kinds of coal-fired equipment, coal-fired boiler equipment accounts for nearly 80%, so the treatment of coal-fired boiler flue gas is the key to reducing pollution. In response to the above problems, three methods are mainly adopted: wet dust removal, electric dust removal, and bag dust removal. Among them, the bag dust collector is superior to wet dust removal in terms of dust removal efficiency up to 99%, use cost, equipment requirements and performance. And electrostatic precipitator, will gradually replace the latter two and occupy the mainstream industrial dust collector market, while the filter material is the key to the dust collector, the performance of the filter material determines the quality of the dust collector, so the filter material is required to have good high temperature resistance. With the rapid development of science and technology, the continuous rise of industries such as electric power, steel, and construction has created a more affluent, convenient, and faster life for people, and at the same time, it has also posed a serious threat to the sustainable development of energy and the environment in our country. . Among the air pollutants emitted by these social industries, the main ones are corrosive chemicals such as high-temperature flue gas and dust emitted by industrial furnaces and garbage incineration. If they are directly discharged into the atmosphere without treatment, they will directly or indirectly affect people's health. Respiratory system, cardiovascular system, central nervous system, immune system, etc., and then threaten the safety of human life.
过滤，就是一种分离、收集分散于气体或液体中的颗粒状物质的过程。一般情况下，较大的颗粒的物质是靠过滤材料的筛分作用而分离过滤的，而粒径较小的物质是靠滤材的吸附捕集作用。目前，主要用于空气和气体过滤的材料主要是过滤纸，采用湿法成型工艺，纤维分布均匀、高集尘能力、低阻、高强度等特点，是理想的空气过滤材料。Filtration is the process of separating and collecting particulate matter dispersed in a gas or liquid. In general, the larger particles are separated and filtered by the sieving effect of the filter material, while the smaller particles are separated and filtered by the adsorption and trapping of the filter material. At present, the material mainly used for air and gas filtration is mainly filter paper, which adopts wet forming process, and has the characteristics of uniform fiber distribution, high dust collection capacity, low resistance, and high strength. It is an ideal air filter material.
玻璃纤维及其复合材料由于高强、耐腐蚀、耐高温、光滑憎水、尺寸稳定不变形，经过浸渍涂层处理后又提高其耐磨性，因此是一种理想的过滤材料。玻璃纤维的生产方法主要分为两种，分别是离心法和火焰法。离心法玻璃纤维直径较大、强度低，过滤效果不好。火焰法玻璃纤维是将熔融玻璃制成玻璃球、棒或块状物，使其再次融化，形成一次丝，在胶辊的牵引下送到燃烧室喷出的火焰中，最后进行收集。火焰喷吹法生产规模小、投资少、占地面小等特点，同时，采用火焰喷吹法制备的玻璃纤维直径小，柔性大和强度高等特点，因此，过滤纸常常选用火焰法制备的超细玻璃纤维。Glass fiber and its composite materials are ideal filter materials due to their high strength, corrosion resistance, high temperature resistance, smooth water repellency, stable size and no deformation, and improved wear resistance after impregnated coating treatment. The production methods of glass fiber are mainly divided into two types, which are centrifugal method and flame method. The centrifugal glass fiber has a large diameter and low strength, and the filtering effect is not good. Flame glass fiber is made of molten glass into glass balls, rods or blocks, which are melted again to form primary filaments, which are sent to the flame ejected from the combustion chamber under the traction of rubber rollers, and finally collected. The flame blowing method has the characteristics of small production scale, low investment, and small footprint. At the same time, the glass fiber prepared by the flame blowing method has the characteristics of small diameter, high flexibility and high strength. Therefore, the filter paper is often made of ultrafine glass prepared by the flame method. fiber.

Basalt fiber is a new type of fiber prepared by melt spinning with basalt ore as raw material. During the melting process, alkali metal oxides are rarely precipitated, and there are basically no harmful substances in the smoke and dust discharged from the pool furnace. It is a green and non-polluting fiber. Healthy fiber material. It has the advantages of non-combustibility, good insulation, excellent mechanical properties, good thermal shock resistance and stable chemical properties, so it can play a greater role in the field of filter materials.
