Recently, the reporter learned from Hunan Qiannan Desulphurization and Dust Removal Equipment Co., Ltd. that the company has overcome many research difficulties in flue gas desulfurization technology and obtained control of high-concentration sulphur dioxide (SO2) emitted from large-scale flue gas-fired coal-fired boilers and non-ferrous smelting furnaces. Technical breakthroughs. The PXJ-type high-efficiency desulfurization and dust removal equipment developed by the company has been listed in the "National Key Environmental Protection Practical Technology" and has been successfully put into operation in more than one hundred domestic flue gas treatment projects.
According to reports, PXJ high-efficiency desulphurization and dust removal equipment has the following advantages: First, the use of less desulfurization agent, low power consumption, less prone to scaling and clogging; Second, good desulfurization effect, up to 95% to 99%, SO2 emissions The lowest concentration can reach 50 mg/m3, and the dehydration rate of saturated flue gas exceeds 97%. Third, the chain-type gas-liquid separation device can effectively remove the droplets of different particle sizes in the flue gas. The moisture content of the flue gas is low. At 75 mg/m3, the downstream equipment is not easily corroded. Fourth, due to the use of an energy-free flue gas heat exchanger, the cooling and warming of the flue gas can be accomplished without consuming any energy.
The desulphurization device enables simultaneous desulphurization and denitrification, and a set of equipment functions. In addition, the water consumption of the device is low, and the utilization rate of recycled water reaches 95%, which is especially suitable for the desulfurization of power plants in arid and dry regions in China. The company's third-generation flue gas wet high-efficiency desulfurization and dust removal complete sets of equipment has been successfully completed for the Anshan Iron and Steel Group No.2 thermal power plant desulfurization project of 480 tons/hour pulverized coal boiler. After monitoring, the overall system cost is only 1/5 of that of similar foreign equipment, the operating cost is only 1/3 of the foreign equipment, and the technical performance indicators are in sync with the world.
