Patent value China's highest Cixi Shihan Xiangcheng technology news

Recently, the "2004 China Top Ten Technology News Persons" campaign initiated by the "Science and Technology Daily" and 15 central news media such as the People's Daily, Xinhua News Agency, and CCTV were announced. Shi Hanxiang, a township entrepreneur in Cixi City, was ranked second in the development of a solution to solve the problem of “three-dimensional pollution” and restore the soil ecology.

Among the top ten science and technology news figures was Huang Boyun, an academician of the Chinese Academy of Engineering who filled the first prize of the National Technological Invention Award for six years, and Sun Quanhui, chief designer of the high-powered computer “Dawning 4000A”.

"The state advocates 'circular economy' is to solve the contradiction between economic development and resource environment." Interviewing Shi Hanxiang, the topic begins with what we consider to be a fashionable "circular economy". "All things in the world are balanced and where they come from." In a simple and simple sentence, Shi Hanxiang has performed it incisively and thoroughly—in the 42 scientific and technological achievements he has obtained in intellectual property, there are 27 patents (including 22 invention patents) filed in the country, and international applications. There are 2 patents. Among these declared patents, there are 15 in the area of ​​circular economy and environmental protection.

In 1993, Shi Hanxiang's village had many companies engaged in smelting, including of course the Ningbo Oriental Copper Company he founded. The smelter emits smoke every day, and a few kilometers away, he can smell the pungent odor from the factory. From 1999 to 2001, on more than 700 days and nights, Shi Hanxiang, the general manager who had only studied junior high school, led researchers to develop an ideal comprehensive technology and equipment for coal-fired smoke pollution control in industrial boilers. This technique grinds the slag produced in the copper smelting process into a slurry, which reacts with the flue gas generated during smelting in a "multi-phase reactor". After absorption of sulfur dioxide, the slag is properly processed to produce “benefits” (a kind of sulfur-rich slag fertiliser), and a new pollution control road with waste treatment and waste conversion as treasure is introduced, and its equipment price Only one-fifth of imports. Afterwards, they boldly declared to Ningbo City, Zhejiang Province, and the State Economic and Trade Commission that an innovative project of “using waste to cure waste and turning waste into treasure” was immediately formally established by the State Economic and Trade Commission.

After the establishment of the project, the company sent the slag "beneficiary" to Zhejiang Jinhua, Lanxi and other places for large-scale promotion tests. The inspection of the slag fertilizer at the Zhejiang Fertilizer Station concluded that the use of "benefits" generally increased the output of rapeseed by 18%-20%. The report of Zhejiang Medical University shows that rapeseed after using "this fertilizer" is more resistant to diseases and the quantity of amino acids is better than that of the field without "natural fertilizer"; however, monitoring results of Zhejiang Environmental Monitoring Center It shows that the desulfurization efficiency is as high as 98.9%, which is 95% higher than the world's advanced technology and is 3.9% higher.

In 2003, this technology won the first prize of China Nonferrous Metals Industry Science and Technology Award and was rated as a national key environmental protection practical technology by the State Environmental Protection Administration. In March of the same year, the value of the patented technology of the Beijing Zhongzheng Yongxin Assets Assessment by the State Authoritative Assessment Body, “Abandoned waste, changed waste into treasure,” was 18.58 billion yuan. It is reported that this is by far the highest value in the evaluation of national patent projects. (Xu Kewen)
