Description
Technical Field
The utility model belongs to the technical field of desulfurization, and particularly relates to an ultralow-emission filter cylinder special for desulfurization.
Background
The pollution of sulfur to the environment is relatively large, the pollution of sulfur oxide and hydrogen sulfide to the atmosphere, and the pollution of sulfate and hydrogen sulfide to water are important points of environmental protection work. Large amounts of coal are burned in production processes such as chemical plants, coke oven plants, thermal power plants, etc., and often contain a certain amount of sulfur elements which release a large amount of SO2 after combustion, and if not treated, cause great environmental hazards. Therefore, these industries are commonly using desulfurization equipment.
The flue gas wet desulfurization process is mainly divided into calcium desulfurization and ammonia desulfurization, wherein the calcium desulfurization has the defects of high energy consumption, high water consumption, high consumption of desulfurizing agent (limestone) and the like, and the byproduct gypsum has large quantity and poor quality (gray smoke containing) and is difficult to compete with mineral gypsum with rich resources, high quality and low cost in China, so that the mineral gypsum can only be piled up as industrial waste; the ammonia desulfurization uses ammonia as a desulfurizing agent, the desulfurizing process has low electricity consumption, low water consumption and wide desulfurizing agent sources, and no discharge of waste water, waste gas and waste residue, and the byproduct ammonium sulfate can be used as a sulfur-based fertilizer, thus being a truly green environment-friendly technology without secondary pollution.
The working principle of ammonia desulfurization is as follows: after industrial smoke-containing dust is treated by a dust remover, the flue gas enters the desulfurizing tower from an air inlet at the bottom of the desulfurizing tower, and is contacted with saturated ammonium sulfate solution in the desulfurizing tower, SO that the flue gas can be cooled down in the process, at the same time, ammonium sulfate crystals are separated out due to evaporation of water in the saturated ammonium sulfate solution, the cooled flue gas enters an SO2 absorption tower device through a demister, ammonia in the absorption tower and water are mixed into ammonia liquor, SO2 in the flue gas is absorbed at the moment, and ammonia is reacted with the ammonia to generate ammonium sulfate. The flue gas after desulfurization is discharged into the atmosphere through a chimney with the height of 120 meters. However, in this desulfurization system, gaseous ammonia reacts with sulfur dioxide, oxygen, water, etc. to form ammonium sulfite and ammonium bisulfate by gaseous phase, solid crystals are precipitated due to evaporation, and are wrapped by gas, so that aerosol is formed in the micron level of superfine powder, and is carried out by high-temperature flue gas, and once the ammonium sulfite and the ammonium bisulfate are inhaled into human body, nose, throat, bronchus, eyes, etc. can be stimulated, serious allergic people can cause death risk, so that an ultralow-emission filter cartridge for emission in ammonia desulfurization is needed, and the ammonium sulfite and ammonium bisulfate solid crystals generated in desulfurization in ammonia desulfurization are filtered, so that the quality of flue gas emission is improved.
For the problems in the related art, no effective solution has been proposed at present.
