On June 5, at the 300,000-ton ore terminal of Lianyungang Port, Guangzhong Ship was carrying out intensive unloading operations. When the ship unloader unloads the cargo on the ship, white water mist is continuously sprayed on both sides of the grab bucket to suppress the mineral dust just raised. Fully enclosed belt lines and bucket wheel machines with "water mist nozzles" actively joined the "battle", from the ship to the yard, the battle against dust pollution in the port was well fought. Lianyungang
Port has attached great importance to the protection of ecological environment for many years. In recent years, in accordance with the instructions of the central, provincial and municipal environmental protection departments and transportation departments, Lianyungang Port has implemented a number of effective measures around the important link of dust pollution in the prevention and control of air pollution in the port. The air quality of the port has improved, and the sense of access of workers and people has been continuously enhanced. Every production link of bulk cargo loading and unloading, storage and transportation at the
wharf may produce dust pollution, which is even more impossible to prevent under the bad weather conditions of strong wind. In order to better suppress the "productive" dust, Lianyungang Port has woven a "three-dimensional protective net" for it.
At the loading and unloading site of imported coal of Lianyungang Port Dongfang Company, the "dust-proof funnel" partner "fog gun spray" instantly lost its vitality. On the rear storage yard, the goods stack is covered with a tight "cover net", and when the car is working, the fog gun truck and the sweeper start working around, so that the dust is nowhere to hide.
"We carry out dust suppression technology transformation for loading and unloading equipment, implement the whole process of water mist dust suppression in the loading and unloading process, and strictly manage the covering and spraying of cargo stacks." Xu He, general manager of Oriental Company, said.
"In the process of transportation, we have also made clear provisions on truck closure, cargo cover, loading height and wheel washing. The main roads and port boundary roads in the port area are guaranteed to be cleaned more than six times a day, and uninterrupted cleaning is carried out during the day." Zhu Yanhong, stationmaster of Weihuan Station of Lianyungang Port Group, said.
The "three-dimensional protective net" can not be built casually, and the introduction of dust-proof and dust-suppression equipment and facilities requires a large amount of funds. Lianyungang Port, as a responsible state-owned enterprise, can still take the initiative to assume social responsibility under tremendous operational pressure, and has never been ambiguous in environmental protection investment.
At present, the open-air storage yard of Lianyungang Port Bulk Cargo Terminal has set up 7500 meters of wind-proof and dust-suppression net, and at the same time, dust-proof barriers such as fences and shelter forests have been built, equipped with 40000 covering nets, about 1000 spray guns, about 100 cleaning vehicles such as sweepers and sprinklers, more than 100 sets of fog guns and 13 sets of vehicle washing facilities. In addition, the dust online monitoring system has covered 10 bulk cargo operation units in Hong Kong, built 72 sets of dust online monitoring equipment independently, and built a comprehensive information management platform for port dust, which can view TSP, PM2.5, PM10 and other monitoring data and meteorological data in real time, and can take more flexible and targeted dust suppression measures. The key to the prevention and control of
productive dust pollution lies in blocking the source of pollution, and the physical isolation of production from the outside world will be the key target of the prevention and control of dust pollution in future ports. On November 9,
2022, the Department of Ecology and Environment of Jiangsu Province and the Department of Transportation of Jiangsu Province jointly voiced their hope to speed up the construction of closed silos in view of the large amount of dust produced in the process of loading and unloading, storage and transportation of bulk cargo yards in ports.
"In the past six months, in order to fully implement the spirit of the document" Jiangsu Province Port and Ship Air Pollution Prevention and Control Work Program " (Suhuan Office [2022] 258) and promote the prevention and control of air pollution in ports, we have actively promoted the construction of closed silos in relevant bulk cargo operation units in accordance with the requirements of" one port, one plan "." Hu Yongtao, chief engineer of Lianyungang Port Group, said that the port had decided to build closed silos in Xuwei Port Area, Xugou Operating Area, Miaoling Operating Area and Guanhe Port Area in batches.
"Air film warehouse has the characteristics of closure, energy saving and intellectualization, which can thoroughly solve the problem of unorganized dust discharge in the process of open-air storage and loading and unloading of goods." Yin Xuecheng, director of Xinwei Port Company, said that the tone of the newly built air film warehouse will be coordinated with the port area, forming a beautiful landscape.
It is reported that Xinwei Port Company will build two air film warehouses with an area of about 200000 square meters and an investment of about 240 million yuan. At present, the project has been completed and public bidding is under way. It is expected that the main structure of 1 # air film bin will be completed by the end of 2023, the completion acceptance will be completed in March 2024, and the 2 # air film bin will also be completed by the end of 2024.
In addition to the construction of bulk grain silos in Miaoling operation area, the construction of closed silos in other three areas will adopt this method of air film silos. According to Hu Yongtao, the air film warehouse is not only a simple closed cover for the storage yard, but also equipped with such systems as fog gun dust suppression system, fire control system, lighting system, monitoring system, access control system, intelligent control system, lightning protection system and harmful gas emission detection system, which realizes the informatization and intellectualization of precise dust control.
In addition, the dust pollution generated in the construction of port projects has also attracted great attention from relevant provincial and municipal government departments in recent years. Lianyungang Port Group has formulated and issued a series of dust control documents in the construction field in response to the environmental protection requirements of the higher authorities. Chen Zhaokun, chairman of
Jiangsu Zhugang, said that according to the document "provention and control Requirements for Further Strengthening Dust Control in the Field of Group Construction" issued by the Group, the company strengthened sprinkling and dust suppression by covering bare ground and materials in time for participating projects, so as to achieve "six in place, six hundred percent and two prohibitions". It adds background color and fineness to the "sky blue" of the port.
"Port dust pollution prevention and control work has a long way to go, we should enhance the awareness of environmental protection initiative, change" I want to do "to" I want to do ", take practical actions to win the battle of air pollution prevention and control, improve air quality, and protect the blue sky of the port." Wang Guochao, president of Lianyungang Port Group, stressed at the port environmental protection work conference.
