Brief description of technology | This technology is suitable for the field of complex industrial waste gas purification. It can realize the coordinated disposal of multiple pollutants, optimize the traditional long-process waste gas treatment technical route, reduce project cost and energy consumption, and significantly improve the stability of the equipment. Integrated high-temperature dust collection and denitrification technology-high-temperature composite filter cartridge technology relies on traditional filtering dust collection devices, adopts high-temperature composite filter cartridge filter components, and embeds a denitrification catalyst inside the ceramic filter cartridge to achieve particulate matter below 420 ° C., nitrogen oxides and dioxin-like substances combined removal function. Coupled with the dry deacidification process, the simultaneous purification of acidic pollutants can be further achieved. | |

technology maturity | At present, the application of high-temperature ceramic membrane materials for smoke purification in China, especially ceramic membrane materials with integrated functions of dust removal and denitrification, has only just begun. Foreign advanced multifunctional ceramic membrane materials and filtration technologies have entered the domestic market through agency methods, and are promoted and applied in the field of high-temperature smoke purification in glass kilns. In terms of the development of multifunctional high-temperature ceramic membrane materials, the Institute of Process of the Chinese Academy of Sciences has used international cooperation projects to cooperate with Japan's Mingdian Institute to carry out the research and development of integrated ceramic membrane materials for dust removal and sales. Shandong Industrial Ceramics Research and Design Institute Co., Ltd. and Zhejiang University have cooperated. Research and development work on integrated ceramic membrane materials for dust removal and denitrification has been carried out. In addition, no other unit in China has carried out research and development work on this product. In view of the good functional characteristics of this membrane material and the urgent demand for filter materials due to serious environmental pollution in China, it provides huge market vitality for this new domestic high-temperature flue gas purification material. | |
technical applicability | This technology has wide adaptability and can be applied to many types of industrial waste gas treatment fields, and is basically unaffected by region, scale and environment. However, since the applicable temperature range of SCR denitrification technology is 170 ° C~420℃, flue gas treatment projects without this temperature range cannot be applied at present. Among them, hazardous waste disposal projects are represented. Since the dioxin treatment process needs to be in 200.~The rapid cooling process is used between 500 ° C, which limits the application and promotion of this technology in this industry. | |
technical stability | The production technology content of the high-temperature composite filter cartridge itself is very high, but the filter dust collector equipment body is mature, which can effectively ensure the long-term stable use of the ceramic filter cartridge. Ceramic filter cartridges require a complete operating system. Pre-spray protection is provided in the early stage of use. The equipment body is equipped with a heating system to ensure the stability of the equipment operating temperature range and reduce the damage caused by thermal stress to the ceramic filter cartridges. | |
technical safety | High-temperature composite filter cartridges are hazardous waste after being abandoned and need to be entered into hazardous waste disposal sites for valuable metal recovery. Ceramic waste aggregate is stabilized and then entered into landfills for disposal. | |
Barriers to technology transfer and promotion | no |
