"Small innovation" releases "big energy"-Haihua Group's technical innovation and innovation to improve quality and efficiency

Strengthening management and reducing costs are effective but limited
.

After approaching the management limit, there is not much room for cost reduction

Focus on technological shortcomings to promote improvement

Looking at the characteristics of Haihua's small reform activities in recent years, the first focus is on the shortcomings and weaknesses of process management, and efforts are made to reduce costs and improve quality and efficiency
.

Limestone is the main raw material for the production of soda ash, and high stone consumption has always been a major problem for Haihua Soda Ash Plant
.

"How to gnaw the hard bones of reducing stone consumption? We compare the reports with our peers every day.

After the new fluidized bed in the calcium chloride plant was put into use in June last year, the powdered calcium has increased substantially compared to the original process route
.

Compared with flake calcium, the price of powdered calcium is low, the sales volume is poor, and it is easy to cause dust

Aiming at technical bottlenecks and seeking breakthroughs

Innovation is the first driving force for improving quality and efficiency

Haihua’s small innovations, small inventions, and small creations aimed at technological bottlenecks and "stuck necks" are also in full swing

Implementing centralized distillation control, Haihua Bromine Plant took the lead in breaking the problem in automatic process control
.

Wang Haiwu, a technician in the distillation workshop, said that distillation is the core process of bromine production.

　　The re-dechlorination transformation of non-premium bromine is another highlight of the plant's innovation
.

Due to the fluctuation of chlorine gas, steam pressure and bromine content of primary acid and the lag of manual operation, non-superior grade bromine is prone to appear

　　"In view of the boiler shutdown or emergency load reduction caused by the inverter failure, we have carried out the power frequency bypass switching transformation of all the defective inverters in the whole plant, and realized the power frequency manual/automatic operation arbitrary control function, and the equipment The operating accident rate has dropped from 36.
8% before the transformation to zero accidents
.

” Yang Aijun, the monitor of the inspection team of the thermal power company’s electrical workshop, said proudly, “After the successful application of this innovative achievement, more than 10 inverter power plants using this brand are all admired.

　　Reduce faults and defects to ensure safety

　　Safety is the greatest benefit and the bottom line for the sustainable and healthy development of an enterprise

Haihua takes full advantage of the wide distribution of QC activities, and "forms troops" in risk management and control and hidden danger rectification

　　The 1# furnace dust removal injection solenoid valve has often failed since it was put into use, which affected the safe and stable operation of the dust removal system
.
"Through on-site follow-up investigation and analysis of the 100-day maintenance record of a running cycle, we finally found that the rupture of the solenoid valve core casing is the crux of the solenoid valve failure, and the root cause of the casing rupture is the vibration during the solenoid valve injection.
Too big
.
" said Liu Haidong, the publisher of the thermal control instrument QC team
.

　　"Before the transformation, the solenoid valve and the diaphragm valve were rigidly connected and fixed on the top of the gas storage tank.
The diaphragm valve vibrated greatly when spraying, driving the solenoid valve to vibrate
.
After the transformation, we separated the solenoid valve and the diaphragm valve, and the rigid The connection was changed to a flexible connection to reduce the vibration when the solenoid valve was sprayed, and there was no failure in one boiler operation cycle
.
” Liu Haidong said
.

　　Based on the position, starting from a young age, seemingly inconspicuous small improvements eliminate the big hidden dangers that may cause accidents
.
In recent years, Haihua has achieved "stable, long-lasting and excellent" operation, and QC research activities have contributed to the indispensable
.
At present, the QC team active in various production links has set off a new round of research enthusiasm
.
"There are 432 research teams like this in the entire group, and 627 projects have been established
.
" Wang Zongshou, the quality management manager of the QHSE department of Shandong Haihua Group, said excitedly, "QC teams are spread across the company's various systems, production lines, and processes.
, Has shown its skills in the battle for high-quality development of enterprises, has become an important platform for gathering the wisdom of employees, an effective carrier for activating employees’ innovative vitality, and has promoted the in-depth development of activities for reducing costs and improving quality and efficiency
