武钢1700冷轧厂酸洗线投产将近十年来,有些化工设备经常被腐蚀损坏,更换备件消耗了大量资金,且有些设备已趋于老化,按国外常规已需要进行更新。这条目前我国自动化程度和产量最高的生产线,正在生产着国家急需的短缺薄板钢材。为保证生产正常进行,我们与国内有关厂家合作,近年对几种重要而易损的化工设备进行了消化移植和改造,取得了较大的经济效益。 1.盐酸再生机组尾部风机的改造 尾部风机担负着使酸再生系统产生负压,把在反应炉里生成的HCl等气流输送到吸收塔里再生为新盐酸,并将CO_2、N_2、H_2O等气体排放至大气中。它对全机组的生产和再生盐酸的质量起着十分重要的作用。
Nearly a decade has passed since some pickling lines were put into operation at WISCO 1700 cold rolling mill. Some chemical equipment is often corroded and damaged. Replacement spare parts consume large amounts of capital. Some of the equipment has become aging and needs to be updated according to foreign standards. This current production line with the highest degree of automation and output in China is producing short-cut sheet steel products urgently needed by the country. In order to ensure the normal production, we cooperate with the domestic manufacturers, in recent years, several important and vulnerable chemical equipment for digestion and transplantation, and achieved greater economic benefits. 1. Hydrochloric acid regeneration unit tail fan rear Tail fans responsible for the acid regeneration system to produce negative pressure generated in the reactor HCl and other air flow sent to the absorption tower regeneration of new hydrochloric acid and CO_2, N_2, H_2O and other gases Discharge into the atmosphere. It plays a very important role in the whole unit production and the quality of regenerated hydrochloric acid.
