【正文】 ely used in steel, electroplating and steel structure in the process of the acid, Also used to chemical medicine, rare earth in production, etc. Iron synthesis furnace production hydrochloric acid is the present domestic most LvJianChang general use in production technology, Though the absorption process several change, At present most used falling film tower, packed tower level 2 or 3 absorb legal hydrochloric acid. This design there are three main elements: one is the material balance the process of hydrochloric acid synthesis, thermal balance, the second is the synthesizer was equipment sizing calculations and calculation of heat transfer of falling film absorber area, finally drawing a flow chart. This paper reviewed the hydrochloric acid production status and progress, Analyzes the advantages of existing units and the existing problems. To solve these problems, the demand with subject, the existing production technology was improved processing, design the hydrochloric acid device production craft, the design to a certain extent the process of the existing overe defects.
