The traditional wet desulphurization technology mainly comprises a limestone-gypsum method, a double alkali desulphurization method, a sodium alkali desulphurization method, an ammonia desulphurization method and the like. The flue gas desulfurization technology mainly adopts countercurrent spray, alkaline slurry is sprayed from the upper part of a desulfurization tower, and is free to settle under the action of gravity to be in countercurrent contact with flue gas to realize desulfurization reaction, but the diameter of sprayed liquid drops is relatively large, the contact area of single liquid drop and the flue gas is small, so that in order to improve the desulfurization efficiency, the number of times of circulating spray of the slurry needs to be increased, the liquid drops are in contact with the flue gas for many times to improve the absorption effect of the liquid drops on sulfur dioxide, the flow of a slurry circulating pump at the bottom of the tower is very large, the power of a motor is also very large, the power consumption of the slurry circulating pump is.
The particle size of dust in the flue gas is small, most of the dust is 0.1-200 mu m, and the existing flue gas dust removal technology mainly comprises a cloth bag type dust removal technology, an electrostatic dust removal technology and a wet dust removal technology. Because the flue gas contains moisture, dust absorbs moisture and is bonded on a filter bag of the cloth bag type dust collector to block the pores of the filter bag, so that the filter bag needs to be cleaned or replaced frequently, and the application of the cloth bag type dust collector is greatly limited; the main disadvantages of the electrostatic dust collector are that the manufacturing cost is high, the requirements of installation, maintenance and management are strict, high-voltage power transformation and rectification control equipment is required, the power consumption is high, and the occupied area is large; the wet dust removal technology mainly removes dust carried in flue gas through spray water, and liquid drops with smaller particle sizes are still discharged out of a chimney along with the flue gas after being combined with the dust.
With the large-scale popularization and application of the wet desulfurization technology in China, an obvious and difficult-to-overcome defect of the wet desulfurization technology gradually appears, the defect is that the discharged flue gas generates a 'white smoke' phenomenon at the opening of a chimney, the length of the 'white smoke' is generally dozens of meters to hundreds of meters, even a long dragon of the 'white smoke' of kilometers is formed sometimes, strong visual impact is brought to people, and the 'dust rain' phenomenon also occurs sometimes on the ground. The flue gas after wet flue gas desulfurization contains a large amount of vapor, is saturated flue gas basically, and still smugglies a small amount of liquid water droplet in the flue gas, and "white cigarette" is exactly that the vapor in the flue gas condenses the acid that forms and contains the salt droplet, produces direct corrosion to the peripheral steel construction platform of chimney and building, shortens its life greatly, so, how can eliminate "white cigarette" phenomenon is the problem that awaits a urgent need at present to solve.
