According to Datang Power Plant 1*660 MW technical requirement that call for bid technological file that power plant offer, design a set of medicine systems. The concrete system, in order to add phosphate , add ammonia , add and unite the ammonia and add Sulfate system automatically. The design of this device should realize the following function : (1) The medicine amount of adding of the device is accurate, in time. (2) The analysis instrument that the device disposes should be able to realize the computer controls, gather and deal with the data in time continuously. (3) Device should possess cutting off medicines and boiler operate function that move ahead simultaneously complete, can protect functions such as the apparatus and having autoalarm ,etc. at the same time. Automatic medicine system designing therefrom, utilize AutoCAD make maps method make , add medicine device systematic picture automatically , device electric principle picture , and device level assign , pursue. Keywords: the automatic medicine system; Frequency control; computer control 目 录 摘 要 I ABSTRACT II 目 录 III 第1章 绪 论 1 1.
