The national green technology "supermarket" has newly helped improve the level of social energy efficiency

The National Green Technology Trading Center is located in Xiaoshan District, Hangzhou. It was established in June last year.

Green technology achievements transform the heat. The reporter learned from the National Green Technology Trading Center that as of August 19, the green technology in the field of energy-saving and environmental protection of the center platform reached 530, and a total of 30 transactions were reached. The ratio is more than 70%.

In early August, Hangzhou Nuo Bang Non -woven Co., Ltd. purchased a green technology on the platform. Earlier, the company completed the drying process through natural gas combustion, and a large amount of smoke was discharged directly, causing the remaining heat to disperse. How to recover this part of heat? The "three -dimensional thermal exchange green technology" provided by the State Grid Zhejiang Economic Research Institute gave solutions: through the heat exchanger, the heat of about 110 ° C in the dry tail gas was recycled, and then used to preheat the preheating process of the front road heating process. Link.

"In two months, you can install and debug new equipment." Chen Jun, director of the office, said that after the use of green technology, it is expected that a single production line can save 40,000 cubic meters of natural gas per year, reduce energy consumption by 10%-15%, and save saving The expense expenditure was 17-18 million yuan, and the static recovery period was about 3.74 years. At the same time, the condensation water generated during the heat exchange process can also dissolve about 10%of nitrogen oxidation compounds in the flue gas to reduce air pollution.

Ningbo Beilun Gaotang Comprehensive Energy Station.

Green technology is not only very popular among industrial enterprises, but also widely used space in public infrastructure.

In the hot summer, the IT device of the Ningbo Gaotang substation was immersed in the coolant, and the heat generated by the liquid flow was taken away, and it was recycled and then used for living water. Compared with traditional paths such as exhaust fans, the energy saving effect of immersion liquid cooling technology is more significant. After the application, the substation can save more than 490,000 kilowatt -hours per year, which can reduce the operating cost of more than 32.5%; it is equivalent to reducing 152.07 tons of margin coal and 489.09 tons of carbon emissions.

It is reported that this technology is developed by the technical team of the Zhejiang University Shuangchuang College and the State Grid Zhejiang Power Double Innovation Center. Compared with existing liquid cooling technology, the new generation of liquid cooling technology also has low cost, small occupation, high reliability, etc. Advantage. Through the National Green Technology Trading Center, this technology has been applied at the National Supercomputing Center of Wuhu in Anhui, and will soon settle in Zhangye, Jiuquan and other places in Gansu, and bring Zhejiang green technology to the national stage.

Since its establishment in June last year, the only national green technology "supermarket" in the country has covered six major areas including energy -saving and environmental protection, clean production, clean energy, ecological protection and repair, urban and rural green infrastructure, and ecological agriculture. Eight major industries such as power, chemical industry, and construction have a total of 1,548 green technology.

The center also builds an online and offline trading platform. Among them, the "intelligent retrieval" module has set up a global intelligent retrieval system, which can provide comprehensive intellectual property related information and evaluate the value of green technology. At present The item system, through a series of activities such as "unveiling the list", technology salon, project roadshow, and achievement of results, improve the green market activity.

"We are carrying out technical collections in the application of" Energy -saving and Carbon E -Book "to display dozens of high -quality green technology and data information such as browsing and docking." Liu Zhoubin, the National Green Technology Exchange Center, said that it will also open up "Zhejiang Zhejiang The "platform of the Ryo, precisely pushes related green technologies to the enterprise, and promote the low -carbon development of the whole society.
