Design Of The Big Power Silicon Rectifying Tank Cooling Water Automatic Supply System

At present, the cooling of the big power silicon rectifying tank use water cooling basically in civil and international. With the rectifying voltage and the electrolysis current to go up to the request that the cooling water system is also more and more high, in addition to the request of the water pressure,water temperature and flux, is also more strict to the request of the water quality.To the big current silicon rectifying equipment, because it's current, power exhaust and producing heat is greatly, so its cooling is very important problem. Its cooling means divided into three sorts: the wind cooling, the oil cooling and the water cooling. The most widespread cooling mode what to use water cooling in the electrolysis with the big current silicon rectifying equipment. Because the rectifying tank has high requirements to its circulation cooling system, so adopt the shut type circulation cooling system, namely include 2 water systems: the twice water systems and the once water system, two systems isolate thermodynamic energy and waterpower by the plank type heat exchanger the change of and water power.PLC technical development can satisfy more demands of the industrial automatization, can also provide a safe dependable and more perfect solution for the automation application. But in the design the process of this system, according to the system function request and other factors, for example, the system analog and switch nodes not much, apply function is opposite simple, comprehensive consider that PLC act as the master control system has mature applied experiences in the industry, so make certain the PLC as master automation control system.Main contents of the paper include to makes use of PLC automatic control technology to real-time collect to the circulating water quality and supply automatically, and on-line inspect states of the supply water equipments and parts. Pass the sound and light signal notice control room supervisors;the further enhance the running credibility of the rectifying equipments.
