Problems solved by technology
The rotary flue gas reheating technology (GGH) is used to reheat the outlet flue gas by using the heat of the flue gas entering the desulfurization system, which can solve the problem of white smoke plumes, but the rotary flue gas reheater has problems such as air leakage, corrosion and blockage , seriously affecting the safe and stable operation of the system
The indirect reheating technology (MGGH) can avoid the disadvantages of the rotary flue gas reheater, and at the same time solve the problem of the white plume of the sintering flue gas, but the disadvantages of high investment and operating costs restrict its promotion and application

The invention discloses a system and a method for removing white smoke plume of sintering flue gas. The system comprises a recirculation cooler, a sealing cover, a hot air channel, an air blower and achimney, wherein the sealing cover for sealing the recirculation cooler and collecting hot air from the recirculation cooler is arranged on the top part of the recirculation cooler; the hot air channel for conveying the hot air is connected to the sealing cover; the air blower for overcoming the system running resistance is mounted on one end of the hot air pipeline, and the other end of the hotair channel is connected to the chimney; the hot air, pressurized by the air blower, in the hot air pipeline, is mixed with the flue gas subjected to wet desulphurization, and then the mixed gas is transferred into the chimney for exhausting. According to the system and the method, the flue gas subjected to desulphurization is reheated through large quantities of waste gas waste heat produced by asintering machine, and thus the problems of white smoke plume and gypsum rain of the sintering flue gas can be solved with low cost and low operating expense.
Description
technical field [0001] The invention relates to the field of flue gas pollution control, in particular to a system and method for eliminating white plume of sintering flue gas. Background technique [0002] The sintering process of iron and steel enterprises produces a large amount of flue gas, which contains sulfur dioxide, nitrogen oxides, dust and other pollutants. In order to reduce the emission of sulfur dioxide in the sintering process, iron and steel enterprises have carried out sintering desulfurization transformation. At present, wet flue gas desulfurization technology (limestone / gypsum method, lime / gypsum method, magnesium method, ammonia method, etc.) is the preferred process for sintering flue gas desulfurization in iron and steel enterprises. The implementation of the sintering flue gas desulfurization project has effectively reduced the emission of sulfur dioxide in the flue gas. However, the flue gas reheating process is not used in wet desulfurization in my c...
