Environmental Protection! CIE Once Again Won the First Prize of Patent Award in Hunan Province

2023/04/24

On the morning of April 23, at the "Launching Ceremony of Hunan Intellectual Property Publicity Week" co-sponsored by the Administration for Market Regulation of Hunan Province and Intellectual Property Office of Hunan Province, the patent of "activated carbon thermal desorption method and device" independently developed by CIE and its subsidiary Hunan CIE Energy Conservation and Environmental Protection Technology Co., Ltd. (hereinafter referred to as "CIEE") won the first prize of 2022 Patent Award in Hunan Province, which is the fourth time that CIE has won this honor in recent years.

 

 

The patent of "activated carbon thermal desorption method and device" is the core technology and equipment for activated carbon flue gas purification process of CIE. It has pioneered the activated carbon thermal desorption method and device with proprietary intellectual property rights, developed multi-energy level hot air coupling waste heat cascade utilization technology and desorber temperature control system based on heat exchange model, invented gas-liquid two-phase turbulent drying acid production wastewater treatment technology, and solved the technical bottlenecks such as underutilization of heat energy in the traditional desorption system, difficulty in treating acid production wastewater and lag in temperature control. The originally discharged waste heat gas is "turned into treasure" and the thermal energy resources are recycled, thus realizing the efficient utilization of low-level energy and achieving the goal of zero discharge of wastewater. There are 79 patents around this core technology, including 3 PCT patents and 36 invention patents, and 2 of them have been authorized in ROK and Russia.

 

This patented technology is fully and independently implemented by CIEE and has been popularized and applied in sintering flue gas purification projects of many domestic and foreign steel enterprises such as Baosteel, Wuhan Iron & Steel Co., Ltd. and Anyang Iron & Steel Group Co., Ltd. After the implementation of this patent, the desorber system of activated carbon flue gas purification device can reduce gas consumption by 15%~20%, save steam by 25%~35%, reduce activated carbon consumption by 10%~20% and reduce investment in acid production wastewater treatment system by about 50%. This technology has a remarkable energy-saving and emission reduction effect, which can save about 3,968 tons of standard coal and reduce about 9,892 tons of CO2 emissions every year, providing technical support for the development of green steel in China.
