Background technology
In aluminum electrolysis, electrolyte temperature is a very important parameter in production process, and it can directly reflect
The working condition of electrolytic cell, it is necessary to detection in time and control, but due in electrolytic cell temperature be up to 960 degree, and electrolyte corrosion
Property it is strong, there is the shell surface layer of one layer of solidification on surface again, does not find a kind of method for continuously measuring its temperature yet at present, in industry.For
Detection electrolyte temperature, is precisely controlled electrolytic cell running status in time, improves detection operation operating efficiency, prevents artificial detection temperature
Pollution of the degree flue gas that frequently opening cell cover plate is emerged to environment, realizes that automated job is substituted artificial, spy proposes that one kind is automatic
Discontinuous detects the method for aluminium electrolyte temperature, and design invented a kind of automatic discontinuous formula detection aluminium electrolyte temperature be
System.
At present, aluminium electrolyte temperature detection is main using manually with hand-held armoured thermocouple formula thermometer detection mode, i.e.,
It is artificial that first electrolyte top layer shell surface is broken into pieces, then armoured thermocouple probe is stretched into electrolyte, and about 10 seconds kinds are stopped, see
The Temperature numerical shown on thermometer screen is examined, then manual record.This mode is not only time-consuming, inefficiency, and by
Thermocouple stretches into depth and residence time factor influence measurement accuracy in electrolyte；Another thermocouple, which is stretched into electrolyte, to be measured
After when taking out because temperature difference can form one layer of solid crust on thermocouple surface, need to beat during measurement next time, influence heat
The galvanic couple life-span；Manual measurement temperature need to frequently open cell cover plate again, and the smoking gas containing fluorine opened in cell cover plate time slot can be diffused in factory
In room, air and surrounding enviroment in pollution factory building.
Solution to this problem, mainly detects number of times, by original with reduction electrolyte temperature as far as possible at this stage
It is changed to once three days once a day, but it is totally unfavorable to grasping electrolytic cell operation conditions in time, lose more than gain, fail fundamentally
Solve the problems, such as.
