Background
Fossil fuels such as coal and oil are still a main source of current energy sources for human beings, and the influence of the use of a large amount of fossil fuels on the earth environment cannot be ignored; for example, combustion exhaust gas such as coal and oil contains a large amount of sulfur dioxide, which is directly discharged into the atmosphere without treatment, so that serious pollution is caused, and currently, a desulfurizing tower is generally adopted in the industry to carry out desulfurization treatment on sulfur-containing flue gas, especially wet desulfurization equipment with large treatment capacity and relatively low cost is widely used.
The prior desulfurizing tower has different structures, and most of the desulfurizing towers adopt atomizing nozzles to spray and absorb slurry from the upper part of the desulfurizing tower, flue gas enters the desulfurizing tower from a flue gas outlet in the middle part of the desulfurizing tower and reacts with the atomized slurry, so that sulfur dioxide is absorbed, calcium sulfate is formed and is converged in a slurry pool at the bottom of the desulfurizing tower;
the residence time of the flue gas in the desulfurizing tower and the mixing uniformity degree of the flue gas and the slurry, even the flowing speed, the flowing length and the like in the desulfurizing tower can influence the absorption efficiency of the desulfurizing tower; because the height of desulfurizing tower can not be too big, so the residence time of flue gas in the desulfurizing tower is short, flue gas and thick liquid misce bene, can lead to the absorption efficiency of desulfurizing tower to a certain extent not go on, consequently need set up a plurality of desulfurizing towers and carry out repeated purification and make the waste gas of emission reach standard, this will increase place and equipment cost.
In the chinese patent of application number 2018202523290, the name is a desulfurizing tower, disclose a desulfurizing tower, including desulfurizing tower, totally closed thick liquid pond, the desulfurizing tower top is provided with the air outlet, and the bottom center is provided with the leakage fluid dram, the leakage fluid dram is connected with thick liquid pond pipe connection, and desulfurizing tower upper portion one side is provided with spiral whirlwind pipeline, spiral whirlwind pipeline one end and flue gas admission pipe UNICOM, and desulfurizing tower inside center is provided with an upper end confined toper reaction barrel, has the interval between toper reaction barrel and the desulfurizing tower, forms the flue gas and rises the passageway, and the spiral whirlwind pipeline other end passes toper reaction barrel upper portion, and toper reaction barrel inside center installs the jet column, and toper reaction barrel outer wall upper portion is provided with a plurality of secondary shower nozzles along toper reaction barrel circumference, and this desulfurizing tower simple structure, desulfurization effect is good, operation maintenance cost is low. The problems are that only the arrangement mode of the flue gas and slurry spraying device is changed, the mixing of the flue gas and slurry liquid drops is still relatively low, and the residence time of the flue gas in the desulfurizing tower is relatively short.
In addition, for large ocean vessels, the exhaust gas discharged by the large ocean vessels must be subjected to desulfurization treatment, so that the marine desulfurization tower can be said to be a standard of the large ocean vessels, and the marine desulfurization tower is a considerable and improved problem in terms of cost and space layout under the conditions that the volume of the marine desulfurization tower cannot be too large and the height of the marine desulfurization tower cannot be too high, so that sufficient purification efficiency is ensured, and meanwhile, the space is excessively occupied.
We find that the smoke outlet of the common desulfurizing tower is sprayed out from a great amount of smoke outlet, the area lacks slurry liquid drops, which is unfavorable for desulfurization reaction, and if the smoke discharged from the smoke outlet is quickly and fully mixed with the slurry liquid drops, the working efficiency of the desulfurizing tower can be improved to a certain extent, and the design thought is provided for improving the purifying efficiency of the desulfurizing tower, especially the marine desulfurizing tower.
