Degree and cleaning performance, solve a series of limitation present in prior art monitoring.By apparatus of the present invention, can measure clear in real time
The corrosion rate of washed journey and scale removal situation, can find that the corrosion that cleaning process occurs exceeds standard and the thing of scale removal poor effect in time
Therefore hidden danger.
The utility model of Application No. 201520590272.1, it is provided that a kind of Boiler Chemical monitoring device, including
Monitoring pipe and clamping device, clamping device is two ring flanges connected by some screw rod correspondences；Monitor that pipe coordinates to be arranged on
Between two ring flanges；It is respectively equipped with and the through hole monitoring that pipe two ends match in the middle part of two ring flanges；The two ends of screw rod are provided with
Screw thread, monitor pipe by adjust screw rod two ends nut be clamped between two ring flanges, Chemical cleaning monitoring device install and
Dismounting simple and flexible, is not strict with the length monitoring pipe, it is not necessary to Chemical cleaning being monitored, pipe carries out the processing of complexity,
Fixing device easily connects with purging system.
Above-mentioned patent provides detection method and device mainly for cleaning quality, when not mentioning Chemical cleaning, cleans
The on-line monitoring of process.This patent devises a kind of on-Line Monitor Device, to solve the problems referred to above present in Chemical cleaning.
Summary of the invention
The problems referred to above that this utility model exists for existing Chemical cleaning, it is provided that a kind of Process of Chemical Cleaning is supervised online
Survey device.
Described a kind of Process of Chemical Cleaning on-Line Monitor Device, by detector unit, Programmable Logic Controller, host computer and shifting
