Today (February 14), CNOOC Limited announced that the world's first integrated waste treatment and power generation facility, the first phase of the Hong Kong Integrated Waste Management Facility, has been completed and delivered at the Zhuhai site.
The first phase of the Hong Kong Integrated Waste Management Facility (HKIMF) project is to build a new 16-hectare artificial island in the waters near Shek Kwu Chau in Hong Kong, and build facilities such as waste sorting**, waste-to-energy incineration, seawater desalination and sewage treatment on the island.
Wang Changlin, Project Manager of Hong Kong Integrated Waste Management Facility Phase I: The project uses modern advanced incineration technology as the core treatment solution, applies advanced technologies such as automatic control of waste incineration, efficient heat utilization, and innovates the deep reuse process of tail flue gas, which can effectively improve the level of energy conservation and environmental protection.
The first phase of the Integrated Waste Management Facility includes 17 key treatment modules with a total weight of 50,000 tons, equivalent to 12 times. It is composed of more than 110,000 structural parts and 270,000 equipment parts, connected and fixed by nearly 2 million bolts, and the total length of the installation pipeline can be more than 1 circle around the third ring road of Beijing. The project is built with a modular design, which is more integrated and more compact than similar projects.
Yang Cheng, Deputy Project Manager of Hong Kong Integrated Waste Management Facility Phase I: For the first time in the world, the construction method of large-scale module full bolt connection has been realized, and a number of technologies such as multi-discipline integrated construction and all-discipline integrated management have been innovated, which has greatly improved the level of digital visualization construction technology and project management efficiency, shortened the construction period by 20%, the dimensional error is less than 5 mm, and the precision control has reached the advanced level in the industry.
After the first phase of the project is put into operation, the daily household waste processing capacity can reach 3,000 tons, and the average annual power generation is about 4800 million kWh, which can be used by 100,000 households, reduces carbon dioxide emissions by 440,000 tons per year, and can effectively alleviate the pressure on solid waste landfills in Hong Kong.
60 seconds to review the construction of a waste-to-power facility.
In September 2020, the project started construction in Zhuhai.
In October 2021, it was launched**.
In April 2023, the pipeline installation was completed.
In June 2023, the module completed the pressure test.
In December 2023, the module was weighed.
In January 2024, all modules of the project will be completed and delivered.
The improvement of waste treatment capacity will boost China's green and high-quality development.
With the rapid development of the economy and the improvement of living standards, a large amount of municipal solid waste has become a serious social problem. How to reduce, recycle, and harmlessly dispose of garbage has become the main direction of thinking when solving the problem of garbage.
Waste-to-energy generation is an efficient waste treatment method that incinerates garbage through a special boiler and then generates electricity with the heat generated by a steam turbine.
In recent years, China attaches great importance to the development of the waste-to-power industry, and has made significant progress in waste-to-power generation technology. During the "13th Five-Year Plan" period, more than 250 domestic waste incineration plants have been built across the country, and more than 500 domestic waste incineration plants are in operation, with a processing capacity of 580,000 tons per day.
Up to now, the proportion of waste treatment power generation in some developed areas of China has increased to more than 60% of the total amount of harmless treatment, and the waste treatment and power generation technology continues to develop in the direction of large-scale and fully automated.
