Air filter air conveyor that is, refers to air pollution particles almost completely removed. Further than the air purification, air purification for many industrial processes for dealing with air pollution with less stringent requirements of the occasion. Air conveyor technology is the science and technology over the past century with the development of modern industry and gradually form an integrated technology, which refers to the application of air purification equipment, pollution control dust particles or through the air circulation conveyor belt to catch suspended particulate matter air set to protect the environment and human health, it is in the air conditioning, ventilation, dust and other fields has been widely used.In recent years, the air conveyor technology research and development in the filter media, conveyor belts and conveyor belt mechanism of the development and application of equipment has made great progress. In this paper, the air conveyor belt at home and abroad in recent years the development of technology and the achievements made air conveyor technology research and development issues to be addressed.Filter can be dispersed in a fluid dispersion of solid particles in the material separated from the porous material, diffusion of the fluid can be gas or liquid. The types of filter media fiber filter, porous membrane, and coated media. Filter determines the effectiveness and efficiency of conveyor belt process, which determines the development of the air conveyor technology. It is widely used in indoor and outdoor air quality, quality control. In addition, new air conditioning belt, recycling processing and use of air and environmental protection, machinery, electricity, coal, ceramics, chemicals, medicine, light industry, chemical fertilizer, pesticides, food processing, port transportation, roads and other transportation lines widely used in various industries are subject to technical and synthetic fiber filter media belt.The rapid development of media production. In the early 20th century, 50, no filter manufacturing plant in China, the market has not dedicated media products; 60's belt to gradually fiber textiles as media, applied to all areas of industry to meet the needs of different industries, for various different uses made of synthetic material conveyor belt fabric with acid and alkali, high strength, smooth fibers and other characteristics; 70's did not, made of polyester cloth filter 208 for the conveyor belt technology to promote the birth of the first applications approved media; 80 and modeled on the Japanese product development 729 polyester woven filter media, and the need for belt dust needle felt filter developed to improve the efficiency of bag filter dust; the mid-90s, the successful development of scientific and technical personnel film filter, which uses a special process, the PTFE porous film composite in woven, non-woven fabric or glass fiber filter on the filter, the filter is formed when a dust belt layer, to achieve the surface conveyor belt, for the efficient provision of high quality low resistance and energy-saving conveyor belt material.Current media trends are: (1) by two-dimensional structure of woven fabric conveyor belt to the three-dimensional structure of the non-woven fabric conveyor belt development of the short slender filament woven conveyor belt fabric to fabric development, the Complex filament twist conveyor belt cloth monofilament cloth to development; (2) from conventional to high-performance synthetic fabric conveyor belt, multi-functional, high quality conveyor belt fabric development, the development of synthetic filter media to the film .At present, the majority of synthetic fiber filter media and composites manufacturing enterprises finishing equipment is still not perfect, product variety and performance development are subject to certain restrictions, some special-purpose media had to rely on imports. Further study should be finishing the existing filter media, and application of composite technology, research and development of new media to improve the performance of domestic media, the formation of relevance and applicability of the product.Air conveyor technology is made by different forms of media to achieve the air conveyor belt rollers. To increase the effective area of idlers, conveyor belt optimize performance, the structure of the air rollers have been the original form of the development of a single board to the pleated shape or cylindrical shape, long cylindrical, stacked disc-shaped and the matrix form. The earliest domestic high roller was born in 1964. 20th century, early 80s, began to enter our country abroad, roller, it promotes the development of China-made roller. In recent years, China has begun to study static air electret made roller. Is the so-called long-term storage of electret charge of the electrolyte material, that some methods used to make fibers with a charge long-term use of electrostatic capture mechanisms to improve collection efficiency roller. At present, the existence of domestic production of roller production standards and testing standards are not uniform, the efficiency test method is not strict, great variety and size of product specifications and other issues not uniform; the same time, in microelectronics and precision machinery industry, high rollers have been purifying effect can not meet the requirements of domestic sub-efficient, ultra-high roller to be developed. These problems requires the use of standard management and to increase research into ways to further refined solution. Now often used in residential air-roller, office, commercial and industrial buildings clean room, HVAC system, laser surgery room, air conditioners and other occasions.Foreign conveyor belt material development the new trends are: the non-woven fabric conveyor belt materials, composite materials, the development of membrane technology in the conveyor belt, to the use of high-tech, high-performance glass fibers, polytetrafluoroethylene, aromatic polyamide fiber, carbon fiber , metal fiber and other materials developed multi-functional development of conveyor belt material.Overseas production of conveyor belt materials research applications, has formed a more complete system. Each cloth material properties, such as ventilation, strength, ability to retain particles, which have a complete set of tests and testing means. The development of new materials, filter cloth is increasing. Cleaning in order to reduce the resistance, the foreign media from the beginning weaving class class to the fiber grating filter transition. Fiber grating type fiber filter is a root to form the upper and lower longitudinal fence, conveyor belt when the layer is not satisfied with the fence, add another layer of fence, conveyor belt until the desired effect. In order to reduce leakage of dust and improve conveyor performance, reduce costs, extend life, the small diameter of the glass fiber and high temperature strengths of synthetic fibers, made of composite needle felt filter.In recent years, with the high-tech intervention, the development of new textile materials, foreign conveyor belt technology has medical, new material extraction, and other high-tech sectors.The development roller in the air in recent years, electret electrostatic air roller application of more high-performance for foreign air roller. Some developed countries such as the United States, Japan and other countries, has developed a few years ago to produce semiconductor components used 64MD level and above, the air conveyor efficiency of 99.999999% (0.12 ~ 0.17μm) than the ultra-efficient air-roller. Domestic and foreign enterprises in this regard are a lot worse.
