Problems solved by technology

However, because the suspended sulfur entrained in the gas will adhere to the surface of the mist trapping packing, after long-term accumulation to a certain thickness, the tower resistance will increase, the demisting efficiency and desulfurization efficiency will drop sharply, and even the tower will be blocked.
In actual production, it is necessary to stop production frequently, manually enter the tower to clean the mist trap packing, or even replace the mist trap packing, resulting in huge waste of manpower and material resources, seriously affecting the normal operation of the desulfurization process

Abstract

The invention provides a desulfurization tower defogging device and a desulfurization and dust removal device, and relates to the technical field of environmental protection equipment. The desulfurization tower defogging device provided by the invention is arranged on the top of a desulfurization tower, and comprises a ventilating pipe, defogging components and an exhaust fan, wherein each defogging component is of a ring structure formed by blades, the diameter of the inner ring of each defogging component is one sixth to one fourth of the diameter of the ventilating pipe, so a center hole can better discharge liquid in gas, if the center hole is too large, the discharge is not complete enough, and if the center hole is too small, the discharge is difficult to realize. The outer ring of each defogging component is connected with the inner surface of the ventilating pipe, the blades are divergently distributed like spokes of a wheel, the blades are placed obliquely, and an angle formed by the surface of each blade and the cross section of the ventilating pipe is 60 to 80 degrees. Such a stacking method can well keep liquid drops off. A plurality of defogging components are arranged, several defogging operations can be conducted, and the effect is better.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a demisting device for a desulfurization tower and a desulfurization and dust removal device. Background technique [0002] In recent years, the construction of coal-fired power plants in my country has experienced a peak period. On the one hand, the capacity and parameters of the units have been continuously improved, and a large number of new power generation technologies have been applied to coal-fired units; on the other hand, as the society's environmental protection requirements continue to increase, Pollutant emission standards for coal-fired power plants have become increasingly stringent. For the SOx pollutants contained in the flue gas of coal-fired power plants, my country mainly adopts wet desulfurization technology for control. This technology is relatively mature and reliable, and plays an important role in the control of flue gas SOx emis...
