Dust removal solutions for the power industry

―Equipment selection: bag dust collector

Foreword:

On December 2, 2015, the executive meeting of the State Council decided to fully implement ultra-low emission and energy-saving transformation of coal-fired power plants before 2020. At the same time, the Ministry of Environmental Protection, the National Development and Reform Commission, and the National Energy Support policies such as the Work Plan for Ultra-Low Emission and Energy-Saving Transformation of Coal-fired Power Plants and the Notice on Issues Concerning the Implementation of the Ultra-Low Emission Electricity Price Support Policy for Coal-fired Power Plants to accelerate the process of ultra-low emission transformation of coal-fired power plants. So far, my country has officially launched a comprehensive work on ultra-low emissions from coal-fired power plants. Ultra-low emission is a systematic project, and there are many challenges in the implementation process, as well as many problems and "pain points". The decision of the State Council clearly stipulates the implementation time of ultra-low emission, which is close to or reaches the emission standard of natural gas gas turbine units, and clarifies the emission limit, that is, under the condition of the benchmark oxygen content of 6%, the emission concentrations of nitrogen oxides, sulfur dioxide and soot are not respectively Above 50 mg/m³, 35 mg/m³, 10 mg/m³.

Selection Scheme of Dust Removal Equipment in Power Enterprises

Coal-fired boiler bag dust collector is a key environmental protection equipment for power generation enterprises. Our company transformed the electrostatic dust collector into a bag dust collector, removed the power supply system of electrostatic dust collector, and did not change the original structure of the electrostatic dust collector shell and the inlet and outlet smoke boxes. It is reorganized to make it a dust pre-separation device, which solves the problems of unburned coal particles wear and filter bag burning. In order to achieve higher emission standards, zero leakage of the clean air chamber is achieved, and no leakage is achieved by the bypass valve. The bag dust collector of the power plant adopts the sub-chamber positioning back-flushing mechanism and the automatic tensioning device, which has a simple structure and reliable operation. service life. The dust removal equipment of coal-fired power plants adopts the technology of compartmentalized bag dust collector, which is different from the introduction and digestion of foreign technologies by other domestic manufacturers. There are obvious advantages. The bag dust collector protection is more optimized, the ash cleaning system is greatly simplified, the operating reliability of the unit is significantly improved, the operating cost is greatly reduced, and the price is only half of the foreign product. It is a major invention developed by my country and suitable for China's national conditions. All products from design to localization are realized.

Transformation of dust removal equipment in power enterprises

At present, the types of dust collectors mainly include electrostatic dust collector, bag dust collectors, wet dust collectors and cyclone dust collectors, among which electrostatic dust collector and bag dust collectors are the most widely used, wet dust collector and cyclone dust collectors are relatively limited. The working principle of the electrostatic dust collector is to use a high-voltage electric field to ionize the flue gas, and the dust charge in the air flow is separated from the air flow under the action of the electric field. The negative electrode is made of metal wires with different cross-sectional shapes, which are called discharge electrodes; the positive electrode is made of metal plates with different geometric shapes, called dust collecting electrodes. In recent years, my country's electrostatic dust collector have achieved rapid development and wide application, and the number of electrostatic dust collector produced and used ranks first in the world. Moreover, electrostatic dust collector is still the absolute mainstream dust removal equipment for ultra-low emission of coal-fired power plants. Statistics from China Electricity Council show that the market share of electrostatic dust collector in the power industry is about 66.4%. Compared with electrostatic dust collector, bag filter has high dust removal efficiency, flexible use, simple structure and small investment. At present, the proportion of bag filter in steel, aluminum, waste incineration and other industries has reached more than 90%.
