Monitoring data of the hottest domestic ultra-low

The monitoring data of domestic ultra-low emission monitors "on duty" in coal-fired power plants can be remotely transmitted

the Ministry of industry and information technology clearly mentioned in the "opinions on accelerating the development of environmental protection equipment manufacturing industry" on air pollution prevention and control equipment that it is necessary to promote ultra-low emissions from coal-fired power plants, as well as steel, coking, nonferrous metals, building materials Application demonstration of multi pollutant collaborative control in chemical and other non electric industries and volatile organic compounds control technology and equipment in key fields

recently, the project team of "research and development and industrialization of key technologies of ultra-low emission monitoring instruments for coal-fired pollutants" has developed a series of monitoring instruments, filling the domestic gap, breaking the technology and market monopoly of foreign instruments, and making domestic ultra-low emission monitoring instruments applied in coal-fired power plants for the first time

"due to the domestic failure to break through the relevant core technology, the technology of this kind of instrument is monopolized by foreign countries." Zhufahua, the project leader, the president of Guodian Environmental Protection Research Institute and the director of the National Key Laboratory of atmospheric physical simulation and pollution control for environmental protection, said that the researchers of the project have overcome the technical bottleneck, achieved the goal that the important indicators of instrument monitoring are better than those of similar foreign instruments, and promoted the progress of ultra-low concentration pollutant monitoring technology by ultraviolet spectroscopy in China

it is learned that at present, there are more than 300 ultra-low concentration monitors developed by the project. 5 The application of built-in large-scale CPLD programmable devices and instruments in nearly 100 ultra-low emission projects of coal-fired power plants is equivalent to installing a "thousand mile eye" for ultra-low emission projects of coal-fired power plants. The monitoring data can be remotely transmitted, and the technical team can better guide the efficient and stable operation of ultra-low emission of coal-fired power plants, which is widely used in iron and steel metallurgy, factories and mining enterprises, quality supervision, colleges and universities, scientific research institutes, construction materials Material analysis, inspection and supervision in aerospace and other industries

Zhu fahua said that great difficulties were encountered in the transformation of project achievements at both technical and non-technical levels

at the technical level, "when we achieved a series of technological breakthroughs and moved the instrument from the laboratory to the site with great joy, it only ran for about 2 weeks, and the stability problem occurred." Zhu fahua said. In the next six months, the whole team focused on the stability of the instrument. After countless laboratory and field tests and literature review, they finally found the reason and solved the problem through patented technology

"in non-3, the main machine of hydraulic material testing machine should be prevented from being put into the technical level in the handling process. We have encountered a very embarrassing practical problem, especially in the power industry. Many people believe that domestic instruments have a gap with foreign imported instruments in terms of stability, reliability and product performance. Therefore, no one dares to take risks to try to use our products." Zhu fahua said

in order to turn the project achievements into productivity as soon as possible, Zhu fahua's project team used both self-developed instruments and foreign imported instruments in a coal-fired power plant. After three consecutive months of comparative monitoring, the results were designed specifically for the use of injection molding and extrusion molding in the medical and food industries. It showed that several key indicators of the instruments developed by Zhu fahua's project were significantly better than those of a foreign well-known instrument company. In the face of a large number of comparison data and facts, users take the initiative to request the use of domestic instruments to replace imported instruments
