[0003] Since the existing desulfurization and denitrification devices rely on the dust removal filter element to adsorb and separate the dust and other impurities in the flue gas, the dust removal filter element is an important working part of the device. Since the dust removal filter element in the prior art is fixed inside the dust removal tower, resulting in dust removal The contact between the filter element and the flue gas is not sufficient, which reduces the dust removal efficiency of the device; in addition, the traditional desulfurization and denitrification device controls the reverse ejection of gas through the pulse solenoid valve to clean the dust filter element, thereby avoiding the influence of too much dust adsorbed inside the dust filter element Adsorption effect, but because the high-pressure gas ejected by the pulse solenoid valve cannot fully clean the dust removal filter, this method of dust removal is not thorough enough, which affects the adsorption effect of the dust removal filter

The invention discloses an electric arc type desulfurization and denitrification device. The electric arc type desulfurization and denitrification device comprises a desulfurization cylinder; supporting legs are fixedly connected to the edges of the two sides of the lower end of the desulfurization cylinder; an air inlet is formed in the center of the front end of the annular outer surface of the desulfurization cylinder; and an air outlet is formed in the center of the rear end of the annular outer surface of the desulfurization cylinder. Desulfurization mechanisms are movably connected to the two sides of the inner surface of the desulfurization cylinder, and each desulfurization mechanism comprises two groups of rotating shafts. According to the device, by arranging the desulfurization mechanism, a dust removal filter element rotates while rotating with the center of a second gear as the axis, so that flue gas makes full contact with the dust removal filter element, the purpose of thoroughly adsorbing and removing dust and other impurities contained in the flue gas is achieved, and the dust removal efficiency of the device is improved; and in addition, a cleaning mechanism and the desulfurization mechanism are matched for use, so that the purpose of comprehensively and thoroughly cleaning the outer surface of the dust removal filter element is achieved, and the adsorption effect of the dust removal filter element is improved.
Description
technical field [0001] The invention relates to the technical field of flue gas treatment equipment, in particular to an arc type desulfurization and denitrification device. Background technique [0002] Dust removal tower is a kind of equipment that uses sodium hydroxide, industrial alkaline wastewater or slag water, and boiler sewage wastewater as desulfurizers to separate dust, sulfide and nitrate from flue gas. It is equipped with dust removal filter elements inside. The dust removal filter element is in full contact with the flue gas to achieve the purpose of absorbing dust and desulfurization and denitrification. The dust removal tower is a commonly used facility in boilers and industrial production. [0003] Since the existing desulfurization and denitrification devices rely on the dust removal filter element to adsorb and separate the dust and other impurities in the flue gas, the dust removal filter element is an important working part of the device. Since the dust ...
