Recently, the topic of "Research on the domestication of high-efficiency power equipment for electric dust removal technology in coal-fired power plants" undertaken by Beijing Puyi Site Technology Co., Ltd. was reported under the chairmanship of relevant experts from the CECEP branch.
The "Emission Standard of Air Pollutants for Thermal Power Plants" (GB13223-2011), which was implemented last year, reduced the soot discharge limit from 50 mg / m3 to 30 mg / m3 and in the key areas of 20 mg / m3, The body and its high-voltage power supply put forward higher and newer requirements. Currently, there are many high voltage power supplies that can be applied to the ESPs, represented by DC high voltage power supplies and pulsed high voltage power supplies, and many new types of power supply emerge. One of the new high-voltage power supply in the high-frequency power supply, high-frequency power supply IF, high-frequency high-voltage power supply and pulse high-voltage power supply, with high efficiency, high power factor, energy saving and other features by the industry's attention.
Pu billion Site for many years dedicated to the pulse of high-voltage power supply technology research, the South Korea Pohang Iron and Steel ESP pulse impulse high-voltage power supply technology for reference, that in the study, MPS with dual power supply, to enhance the ratio Resistance dust particles charged speed, the elimination of high resistivity particles of dust anti-corona phenomenon, improve dust removal efficiency; energy saving can be 80 ~ 90%, the overall energy saving is higher than 60%. At the same time with the installation is simple, safe and reliable, small maintenance and other advantages, with broad market prospects.
It is understood that the company has introduced South Korea POSCO MPS-related technology patents, and MPS localization of research, including localization of the experimental testing evaluation system, evaluation of domestic components and complete sets of procurement system construction, production base Construction and MPS sales system and spare parts system construction.
