Daqing Petrochemical Flood Control Work Documentary

"Yesterday, after more than 10 minutes of continuous heavy rainfall, all the nine external outlets in the factory area were unblocked, and the rain and sewage discharge were all separated, which tested our comprehensive treatment effect in the aspect of 'preventing blocking, intercepting and draining." On August 9, at the Daqing Petrochemical Refinery Dispatching Meeting, Dispatching Chief Song Shulin summarized the recent flood control work.

This year's rain is particularly "wayward". Since the beginning of summer, torrential rain has continued to warn and rainfall has continued. The flood control headquarters and flood control emergency commandos at all levels of Daqing Petrochemical Company entered a state of war early. All departments and units strengthened their duty and strictly implemented prevention and control measures before, during and after rain to ensure the safety of the flood season.

Be prepared for a rainy day

At 16: 00 on July 23, dark clouds began to accumulate over Daqing, showing a scene of "dark clouds pressing over the city to be destroyed. At this time, emergency materials such as woven bags, submersible pumps and shovels have been placed neatly according to their types in the flood control material warehouses of Daqing petrochemical units, ready for use at any time.

In order to reduce the impact of bad weather on production, before the arrival of thunderstorms, all units shall, according to the flood control experience and actual situation over the years, reserve emergency materials for key areas such as power systems and sewage stations where water disasters may occur, so as to ensure that flood control facilities such as submersible pumps and generators are in good condition, and sandbags, emergency lights and other items are in sufficient supply.

In order to improve the command and decision-making ability of flood prevention and temporary risks, the dispatching room of the refinery has drawn the rainwater drainage flow chart and drainage ditch distribution management chart of the plant area according to the terrain elevation and drainage flow direction, and has set up "eye of heaven" remote video monitoring in 25 workshop areas of the whole plant to dynamically monitor and control the drainage status of the external drainage port and grease trap 24 hours a day. In addition, according to the characteristics of summer production, the staff of the power supply workshop of the No.3 chemical plant conducted a thorough inspection of the overhead cables in all line sections of the plant, completed the work of completing the cable identification, shifting the groove plate reinforcement, etc., to prevent the groove plate cover from being blown up by strong winds and other problems, thus eliminating the hidden dangers of safe production.

Immediately respond to emergency rescue in the rain

Short-term rainstorm weather is one of the "examination questions" to test the flood control work of Daqing Petrochemical Company. How the towering Tallinn in the installation area can withstand wind and rain, and how to ensure the quality, safety, and progress of the projects under construction, is not as simple as saying "it's raining, collect the clothes.

On July 10, the rainstorm came suddenly, and the precipitation reached more than 100mm in only one hour. Affected by low-lying terrain, the railway line and electric switch at the east entrance of the refinery are flooded, and the motor of the electric switch machine is damaged. If it is not repaired in time, it will seriously affect the delivery of products. The danger is the order. The flood control emergency personnel of the refinery quickly replaced the flooded motor, cleaned up the accumulated water inside the switch machine, swept away the floating objects on the railway line in time, and maintained the reducer, switch, contact and other equipment and parts. The thunder is far away, the rainstorm is gradually resting, the railway line at the east entrance is opened, and the traffic safety in the factory area is effectively guaranteed.

In order to win the battle of "100-day battle" in flood season, the large project headquarters, according to the principle of "sunny outside and rainy inside", makes overall planning for on-site construction, reasonably arranges working procedures, and urges all construction units to erect rainproof sheds in advance for those unsuitable for rainy days or not for the time being, so as to strengthen the protection of on-site electrical equipment and materials.

Touch and discharge hidden dangers to safely pass the flood season

After the heavy rainfall, a large amount of silt and fallen leaves were deposited in the open channel and drainage ditch, resulting in different degrees of blockage. Daqing Petrochemical Company quickly organized personnel in the jurisdiction to clean up the sundries in the ditches to ensure that the accumulated water and blockage were discharged at the first time.

The more intermittent the rainfall is, the less careless the safety work can be. According to the location of the production device and the possible consequences after the occurrence of the dangerous situation, the relevant departments and units of Daqing Petrochemical Company carried out a comprehensive inspection of their respective territories, carefully checked the lightning protection and grounding of drainage facilities, open-air equipment, cable trenches and other places, and immediately rectified the problems and hidden dangers.

In order to strengthen the early warning mechanism, the first chemical plant has set up warning signs at the risk parts of the device, and transferred the important parts of flood control to the posts for patrol inspection and monitoring. The water and gas plant has stepped up its investigation efforts to clear the accumulated water found in the inspection of 68 sewage wells and 11 rain outlets in a timely manner. The fire brigade optimized and adjusted the combat programming, strengthened the professional training of officers and soldiers, improved the rescue ability to ensure that when new rain hit, the personnel can pull it out and the equipment can be used.
