Electric Power Institute successfully contracted the design consulting project of Hebei Jinxi iron and Steel Group Co., Ltd. ultra supercritical gas power generation project

The project is equipped with a set of ultra supercritical primary reheat generator unit. After it is put into operation, about 1.8 billion cubic meters of surplus gas will be used annually, and about 1 billion kwh of power will be generated annually. In this project, the surplus gas produced in the process of blast furnace steelmaking is burned for power generation, which not only reduces the air pollution caused by gas emission into the air, but also turns waste into treasure, and turns surplus gas into high-quality electric energy.

The “ultra supercritical” power generation technology adopted in the project is the most advanced power generation technology in the domestic thermal power industry. Using higher parameters and more efficient power generation technology to comprehensively utilize the by-product gas of steel plant is the most important measure to realize energy conservation and emission reduction and serve the goal of “carbon peak” in the current iron and steel industry, which has strong demonstration significance.

Electric power institute won the bid for the design of Jinta molten salt tower type 100 MW solar thermal power generation demonstration project

The power station is one of the first solar thermal power generation demonstration projects in China. The project can convert heat energy into electricity continuously and stably. It is estimated that 105400 tons of standard coal, 1426.3 tons of smoke and 317600 tons of carbon dioxide will be saved every year after the completion of the project.

Vigorously promoting renewable energy to replace traditional fossil energy is the most important implementation path of carbon peak and carbon neutralization. Solar photothermal power generation technology not only realizes the effective use of solar energy, but also overcomes the disadvantages of unstable power generation, such as photovoltaic power generation and wind power generation. It is one of the renewable energy power generation methods that the world and China focus on.

New energy institute won the bid for EPC project of hazardous waste incineration treatment of Zhejiang Juhua Environmental Protection Technology Co., Ltd

The hazardous waste incineration project of Zhejiang Juhua Environmental Protection Technology Co., Ltd. is supported by a 100t / D hazardous waste incineration line + hazardous waste temporary storage and other ancillary facilities, The advanced incineration line technology, including incinerator (rotary kiln + secondary combustion chamber) + waste heat boiler (SNCR denitration) + quench absorption tower (semi dry process) + dry reactor (adsorption of activated carbon and hydrated lime powder) + air box pulse bag filter + induced draft fan + precooling tower, alkali washing tower (double tower) + chimney, is mainly used to treat Quzhou City and surrounding Jinhua, Guangzhou and other cities The incinerable hazardous waste generated in Lishui and other areas will radiate to the whole province, which will inject new power into Zhejiang Province to win the battle of pollution prevention and control with high standards and continuously improve the environmental quality.

Hazardous waste refers to the waste with hazardous characteristics listed in the national hazardous waste list or identified according to the identification method of hazardous waste stipulated by the state. The so-called hazardous characteristics mainly refer to toxicity, explosiveness, flammability, corrosiveness, chemical reactivity, infectivity, radioactivity, etc., which pose a great threat to the ecological environment and human health, It can be called a real ecological bomb. Recently, the 14th five year plan has also made it clear once again the confidence and determination of the state to comprehensively control hazardous wastes and make up for shortcomings.

On the one hand, the project needs to consider the comprehensive disposal of all kinds of hazardous waste except radioactive waste, explosive waste and polychlorinated biphenyl containing waste, on the other hand, it also needs to consider the impact of future industrial restructuring on the type and quantity of hazardous waste, Therefore, after the completion of the project, it will have a strong ability to adapt to the changes in the composition and quantity of the waste to be disposed of.

The new energy institute won the bid for the resource project with the largest comprehensive disposal capacity of house demolition waste and decoration waste in the province

China United new energy engineering design and Research Institute successfully won the bid for Yiwu Construction Waste Resource Utilization Center project. The project covers an area of 133 mu, with a total investment of 390 million yuan. It mainly deals with the construction demolition waste, decoration waste and other solid waste generated within the scope of Yiwu City, and cooperates with the deep processing of tailings and stone materials from ore mining. The construction scale is 1 million tons of construction demolition waste, 300000 tons of decoration waste, 2 million tons of tailing and stone materials processing, and the comprehensive annual processing capacity is 3.3 million tons, which is the largest project At present, Zhejiang Province has the largest comprehensive disposal capacity of house demolition waste and decoration waste.

The project is equipped with three core production lines and comprehensive closed-loop production facilities. The advanced construction waste pretreatment system is one of the highlights of this project. The treatment system can effectively improve the quality of separated aggregate, reduce the impurity content of aggregate and enhance the use value of aggregate. In addition, after further processing, the recycled aggregate of construction waste is transformed into resource products with high added value, which can be widely used in highway construction, urbanization construction, real estate project construction and other fields, forming a closed-loop industrial chain of green building materials, promoting the sustainable development of engineering construction, and realizing a virtuous cycle of industrial development and ecological protection.

After the completion of the project, it will reduce the resource consumption caused by natural stone mining, effectively solve a series of difficulties such as low resource conversion rate, low end product quality and added value caused by on-site disposal of house demolition waste, and successfully solve the governance pain point of urban solid waste consumption, which has important practical significance for developing circular economy and promoting high-quality green development of the city.

Municipal engineering institute undertakes EPC project of Suichang Hushan Jinzhu sewage treatment plant

The scale of the project is 2000 m3 / d. After the completion of the project, the effluent will be discharged in accordance with the first class a discharge standard of discharge standard of pollutants for urban sewage treatment plants (GB18918-2002), and the discharge of main water pollutants can reach the limit standard of Zhejiang provincial local standard discharge standard of main water pollutants for urban sewage treatment plants (db33 / 2169-2018). This project is an important practice of “two mountains theory”.

Hushan township is located in the southwest of Suichang County, on the development axis of “Wenzhou Lishui Quzhou Shangrao”, at the intersection of “Yangtze River Delta economic zone” and “Strait Economic Zone”, with significant geographical development advantages. The existing water treatment capacity of Hushan township has been unable to meet the existing needs, so it is imperative to build or expand the original sewage treatment plant. In the construction of this project, China United Engineering Corporation analyzed the treatment effect, land area, construction investment, operation and maintenance, environmental efficiency and other aspects, and finally adopted targeted technology to effectively solve the problem.

With the further development of township economy and the gradual improvement of infrastructure, the amount of domestic sewage generated and centralized collection and treatment will further increase. The project is of great significance for strengthening the protection of ecological environment, ensuring the safety of water quality and providing a good living environment for the people.
