Description
技术领域 technical field
本实用新型涉及一种余热发电装置，特别涉及冶金炉高温交变烟气余热发电节能除尘专用设备，属于烟气除尘及余热发电技术领域。The utility model relates to a waste heat power generation device, in particular to a special equipment for energy-saving and dust removal of high-temperature alternating flue gas waste heat power generation of a metallurgical furnace, which belongs to the technical field of flue gas dust removal and waste heat power generation.
背景技术 Background technique
在现有技术中冶金炉烟气的净化装置为冶金炉烟气发生设备、余热利用设施、除尘器通过管路依次连接。In the prior art, the purification device for the flue gas of the metallurgical furnace is the flue gas generating equipment of the metallurgical furnace, the waste heat utilization facility, and the dust collector are connected in sequence through pipelines.
目前通常采用的余热利用设施：水列管余热锅炉、蓄热式热管换热器来回收冶金炉烟气的余热，产生饱和蒸汽等。由于冶金炉烟气温度剧烈波动，含尘量大，普通水列管余热锅炉很难运用于冶金炉烟气的余热回收。目前，蓄热式热管换热器已经成功运用到冶金炉烟气余热回收中，但由于热管的固有缺陷(造价高、不抗冻、不耐高温、使用年限短)，使得蓄热式热管换热器在钢铁行业的普及还面临很多问题。At present, waste heat utilization facilities are usually used: water column waste heat boilers, regenerative heat pipe heat exchangers to recover the waste heat of metallurgical furnace flue gas, and generate saturated steam, etc. Because the flue gas temperature of metallurgical furnace fluctuates violently and the dust content is large, it is difficult for ordinary water tube waste heat boilers to be used for waste heat recovery of flue gas from metallurgical furnaces. At present, the regenerative heat pipe heat exchanger has been successfully used in metallurgical furnace flue gas waste heat recovery, but due to the inherent defects of the heat pipe (high cost, no frost resistance, no high temperature resistance, and short service life), the regenerative heat pipe The popularity of heaters in the steel industry still faces many problems.
同时，由于冶金炉烟气温度波动剧烈，波幅大，余热系统就必须设计得足够大，确保高温烟气也能有效冷却。但实际蒸汽产量却远低于余热系统的最大蒸发量，出现大马拉小车的局面。这就相对减少了余热系统的经济价值，增加了余热系统的投资。At the same time, because the flue gas temperature of the metallurgical furnace fluctuates violently and has a large amplitude, the waste heat system must be designed to be large enough to ensure that the high-temperature flue gas can be effectively cooled. However, the actual steam output is far lower than the maximum evaporation capacity of the waste heat system, resulting in a situation of large horses and small carts. This relatively reduces the economic value of the waste heat system and increases the investment of the waste heat system.
