Reducing costs, improving quality and increasing efficiency, making small reforms and making contributions-Shandong Province QC results released Saihaihua Group's awards

In the recent 2021 Shandong Quality Management Team Results Release Competition organized by Shandong Quality Management Association and Shandong Federation of Trade Unions, three topics selected by Shandong Haihua Group achieved excellent results.
Among them, the soda ash plant "Improved Ultrafiltration Recovery Rate "Won the second prize, and "Reduce the "Red Light Belt" of Track Circuit" by Railway Transportation Company and "Reduce the Number of Failures of High Frequency Electric Power Supply of Wet Electric Dust Removal" by Thermal Power Company won the third prize

Increase the water production rate of ultrafiltration membranes

The low water production rate of ultrafiltration leads to a decrease in nanofiltration capacity, which is a major problem for the Haihua Nanofiltration Refining Brine Project
.

"How to improve the ultrafiltration water production rate, we analyzed the chemical cleaning, step sequence operation and other factors, found the crux on the spot, and finally found out that the main factors affecting the water production rate were the long water backwashing time and the short air-water double washing time
.

Through multiple experiment comparisons, we have reduced the water recoil time by 60 seconds, increased the air-water double wash time by 20 seconds, increased the air-wash step by 40 seconds, and increased the water production rate to 90.

Eliminate "red band" fault alarm

Since the launch of the railway interlocking system, the organization of trains has been informatized and intelligent
.

However, when it rains, 105# level crossing railway crossing due to sealing and short-circuit, the "red light belt" fault alarms frequently appear

"In response to the problem of short-circuit sealing, we found two reasons.
One is that the angle steel of the sleeper plate at the crossing is conductive without insulating joints, and the other is that the raw salt accumulates in the gap between the rubber buckle of the rim groove and the rain melts and conducts
.

" "Locomotive" QC team publisher Deng Enhui said, “We use insulated glass fiber reinforced plastic materials to seal the sleeper plate angles, and use rubber belts and adhesives to connect the existing rubber buckles into a long strip, and seal the rim groove of the crossing

　　Reduce high frequency power failure rate

　　The wet electric dust removal system is a key part of reducing boiler flue gas emissions
.

According to statistical analysis, a period of high-frequency power failure accounted for 62% of the total failure rate of the dust removal system

　　"In order to reduce the failure rate of high-frequency power supplies, we found the'root cause' of the failure through on-site investigations
.

" Gao Feng, the publisher of the QC team of the Rock, introduced, "For the problem of unreasonable high-frequency power supply communication methods, we add a backup background, which can be accessed directly through the switch during communication.

　　Based on the position, starting from a young age, the seemingly inconspicuous small reforms have further tapped the potential of reducing costs, improving quality and increasing efficiency
.

In recent years, Haihua has achieved "stable, long-lasting and excellent" operation, and QC research activities have contributed to the indispensable
