Measurement should be accura就風te: temperature, pressure, flow, liqu鐘了id level, weight.
Control to fine: process control, mater農業ial ratio, trade handover, advanced con業兒trol (APC).
Process to be solid: material balance, 亮電energy balance, reduce waste pol明冷lution, energy saving and 報自emission reduction, stabl錢美e quality, high yield.
The influence of preci開區sion is small: press黃讀ure, temperature, liquid level對訊, weight change fluctuation is small,件計 mature technology, hig東美h measurement accuracy; High pr白對ecision of secondary 要商instrumentation, transmission科綠 network and data processing拿關 and conversion.
The influence of accuracy is l跳刀arge: the medium working co問醫ndition is complex, the flow ch數業ange is large, flow is the most impo答件rtant, the most compl呢放ex, the most difficult老喝 to measure the process par草國ameter; The accuracy of the system is謝人 determined by the accuracy of和她 flow measurement, which is an i坐的mportant measure to save energy相站, reduce emission and increase effic水電iency.
System accuracy: five par器志ameters acquisition and c校票alculation model synthe從去sis control system ac答舊curacy, determines the proces場話s accuracy and product費廠ion efficiency.
Mistake: trade handover precision is車水 important, process contr我畫ol precision is not important.
Process: Process control 厭廠consists of a number o司算f micro-trade transactions機亮, which are accounted for by中南 semi-finished and fi姐山nished products.
Results: If the process contro窗的l precision is poor, 為動material, energy imbalance, proce國明ss fluctuation. Resulting in村現 lower yield, more waste, 弟信more energy consumption, more pollutio現兒n emissions.
Current situation: flowmete對音r types are complicated, th習站e overall accuracy is low, and the accu工店racy level is unreasonable.
Pain point: parameter change, site ins飛術tallation conditions are no姐數t guaranteed, generally ina內校ccurate measurement, error 2%~5%錯商~10%~20% is very comm時機on.
Objective: To save ene外微rgy, reduce emission and increase ef靜水ficiency. It is necess跳南ary to improve the accur一農acy of instrument measurement計明 system and control precision, a這個nd reduce the fluctuation o這短f process.
Solution: The flow meter and co拿器ntrol plan should be conf男好igured and optimized at the plant 做和level at the beginning of construct畫白ion.
