REVIEW: In our country many kinds of coal-fired thermal power desulfurization technology, comprehensive reliability, economy, safety and other factors, limestone - gypsum wet desulfurization technology is the best choice, but also the most widely used desulfurization technology. Because of its high water consumption characteristics, the shortage of water resources in local power plants has become a bottleneck in the construction and development of large-scale coal-fired power bases. In order to solve the above problems, Beijing Fresh Environmental Technology Co., Ltd., which has been devoted to the research and development of high-efficiency energy-saving and environmental protection technologies, independently developed the SPC flue gas water removal technology that can realize the zero-supply of water for wet FGD in 2014 Demonstration application for our country coal-rich water-deficit areas to build coal-fired power projects provide a new water-saving technology line.
On September 19, 2016, "SPC Flue Gas Removal Technology Exchange Conference" hosted by Beijing Fresh Environment Technology Co., Ltd. was successfully held in Hohhot, Inner Mongolia. At the meeting, the R & D staff of the technology, together with guests, experts and scholars from major power groups, design institutes, research institutes and government environmental protection departments, jointly discussed the principle, application effect, reliability of actual operation of SPC flue gas water removal technology, Long-term stability and technical and economic rationality conducted in-depth discussion and exchange.
SPC Flue Gas Removal Technology (formerly known as "Wet FGD Zero Replenishment Technology") was successfully researched and developed independently by the fresh environment in 2014. It is suitable for coal-bearing water shortage areas and provides a new resource for the construction of coal-fired power projects in areas rich in coal and water shortage Of the water-saving technology line, with low operating costs, low investment costs, technology mature and reliable, stable operation.
As early as August 2015, the technology passed the appraisal of the project organized by the Chinese Society of Environmental Sciences. The appraisal panel agreed that the technology has reached the leading and advanced international level and is innovative. The technology is to recover the condensed water from the saturated net flue gas for replenishment of the desulfurization system and the host water under the premise of the flue gas desulfurization and dust removal to achieve ultra-clean, and the second purification of the net flue gas after the recovery of water.
Currently, SPC flue gas removal technology demonstration project - Jingneng Watengfang a 2 × 660MW unit is being implemented simultaneously, will be officially put into operation in mid-next year. At the meeting, the project leader introduced the design and application of SPC flue gas removal technology and said: "The SPC flue gas removal technology is a water-saving power generation technology. Through the application of this technology, Housing power plants every year from the coal-fired flue gas extraction of up to 1 million tons of water, while the removal of pollutants also increased to a new level.
At the meeting, all guests agreed that this innovative energy saving and environmental protection technology is suitable for coal-fired power plants in poor areas and can effectively reduce the consumption of water resources. The demonstration project of SPC flue gas water removal technology of Jingnengfangfangfang Power Plant has the same effect on other similar water resources Water saving in coal-fired power plants in the deprived area is of exemplary significance.
