On June 2, the Chinese Society of Environmental Science organized an appraisal meeting on the results of the "Ultra-low Emission Technology and Application in the Building Ceramics Industry" completed by Foshan Mosen Environmental Engineering Co., Ltd. (hereinafter referred to as "Mosen Environment").
After listening to the project team’s report, reviewing relevant information, and after further questioning and discussion, experts from the appraisal committee agreed that the results reached the internationally advanced level and agreed to pass the appraisal. So far, Mawson Environment has become the only (first) company to win this honor in the field of flue gas treatment in the ceramic industry.
Unanimously recognized by authoritative experts in environmental protection
Mawson Environment's "ultra-low emission technology and application in the building ceramics industry" has reached the international advanced level
It is reported that the experts of this appraisal committee are Li Junhua, a professor at Tsinghua University, Cen Chaoping, a researcher at the South China Institute of Environmental Sciences of the Ministry of Ecology and Environment, Zhang Fan, a researcher at the Chinese Academy of Environmental Sciences, Huang Zhanggen, a researcher at the Shanxi Coal Chemistry Institute of the Chinese Academy of Sciences, and China Building Materials Research Institute. Co., Ltd. is composed of professor-level senior engineer He Jie, professor-level senior engineer Wang Xinchun of the Building Materials Industry Technical Information Institute, and senior engineer Jin Guoting, vice president of Dongpeng Group.
The above-mentioned experts from the appraisal committee are authoritative representatives in the field of domestic flue gas control. Take Professor Li Junhua as an example. As a professor and doctoral supervisor at the Air Pollution Control Teaching and Research Institute of the School of Environment, Tsinghua University, he has long been committed to the research of air pollution control chemistry and key control technologies, which has greatly enhanced the international competition of my country's environmental protection industry in core technologies. Power, Professor Li Junhua was selected into the list of valid candidates for the 2021 academician election of the Chinese Academy of Engineering on April 23, 2021.

At the meeting, experts from the appraisal committee spoke highly of the "Ultra-low emission technology and application in the building ceramics industry" completed by Moson Environment. "Revolving around the ultra-low emission requirements of the building ceramics industry, the project aims at flue gas treatment in finished kilns. Integrated development of medium-low temperature SCR denitrification + multi-stage slow-down cycle semi-dry desulfurization and dust removal technology; spray drying tower flue gas treatment uses SNCR denitrification + bag dust removal technology and technology in 3 construction ceramics manufacturers 6. The production line has been used as a demonstration and tested by a third party: the pollutant emission concentrations are NOX<50mg/m³, SO2<30mg/m³, and particulate matter<10mg/m³, achieving ultra-low emissions.”
If you don’t make a sound, it will be a blockbuster
Mawson Environment creates a new chapter in environmental protection management in the construction ceramics industry
This is a recognition and a spur to Mawson Environment. According to "Ceramic Information", since its establishment in 2005, Molson Environment has been committed to the research and development, manufacturing and operation of environmentally friendly products in the field of air pollutant control, developing and producing products such as dust removal, desulfurization, denitrification, and electronic control equipment.
Based on the fact that my country's atmospheric management field has now entered a period of strict management of policies, pollutant emission reduction requirements are getting higher and higher, and the building ceramics industry is facing various technical difficulties in the process of denitrification, desulfurization and dust removal, Mawson Environment has invested a lot of manpower , material and financial resources to promote the development of ultra-low emissions in the architectural ceramics industry.
According to reports, the project was initiated in March 2019. After more than a year of orderly advancement, the relevant acceptance was completed in June 2020. At present, this technology has been stably used in Anyang Belite and Chongqing Dongpeng. So far, Moson Environment has opened a new chapter in environmental protection management in the building ceramics industry.
▲Anyang Belite Green 4.0 flue gas collaborative intelligent integration project.
▲Chongqing Dongpeng Green 4.0 flue gas collaborative intelligent integration project.
"Ceramic Information" learned that the technological innovation points of Mawson Environment's project have the following three major aspects:
1. In terms of denitrification of ceramic kilns, the medium-low temperature SCR denitrification technology is used, and the denitrification efficiency is improved by passing through a treatment chamber before denitrification. First, the treatment chamber is used to reduce the heat generated by the reaction between water molecules in the smoke and alkaline oxides. It is used in conjunction with the cooling mechanism. At the same time, the mechanism is equipped to absorb the expansion of the viscous dust in the flue gas to avoid the impact of high temperature on the SCR denitrification equipment. , while avoiding sticky dust clogging and improving denitrification efficiency;
▲Denitrification equipment built by Mohsen Environment.
2. In terms of semi-dry desulfurization technology, the high-temperature flue gas passes through a dedicated temperature and humidity control system to ensure that the flue gas humidity and temperature achieve the best desulfurization effect. Through the optimized design, the circulating ash is recycled multiple times without pipeline blockage, which is consistent with Compared with the CFB circulating fluidized bed semi-dry method, it overcomes the problems of desulfurization tower bed collapse caused by unstable flue gas operating conditions and untimely discovery of spray gun clogging;
3. In terms of technology integration, innovative use of medium and low-temperature SCR denitrification technology and improved semi-dry desulfurization and dust removal integration technology is achieved to achieve the function of coordinated and integrated treatment of multiple pollutants in building ceramic flue gas, and is the first in the industry to achieve this simultaneously Ultra-low emissions of three major pollutants: particulate matter, sulfur dioxide and nitrogen oxides.
The results of Mawson Environment's "Research on Ultra-Low Emission Technology and Application in the Building Ceramics Industry" are of great significance. After the implementation of the project, not only the average emission concentrations of dust, sulfur dioxide and nitrogen oxides were reduced by 6.5 times, 5.4 times and 3.25 times respectively, but the operating costs were also reduced. It is roughly estimated that the application of this technology can bring economic benefits of about 10 million yuan per year to enterprises, and with the promotion of technology, it is of far-reaching significance to continue to improve the quality of the atmospheric environment.
