Description

Technical Field

[0001] The invention belongs to the technical field of desulfurization equipment and relates to a large-capacity flue gas desulfurization equipment. Background Art

[0002] Large-capacity flue gas desulfurization equipment is an environmental protection equipment specially designed to treat a large amount of flue gas containing sulfur dioxide. It is mainly used in thermal power, metallurgy, nonferrous metals, chemicals, petroleum, mining and other industries to purify industrial waste gas generated by coal-fired, oil-fired boilers and large industrial furnaces to reduce pollution to the environment. After the flue gas containing SO2 enters the desulfurization tower, it first comes into contact with the desulfurizer. The desulfurizer is fully mixed with the flue gas through spraying and other methods, so that SO2 is absorbed into the desulfurization liquid. In the desulfurization liquid, the desulfurizer reacts chemically with SO2 to generate sulfides. These reactions not only effectively remove SO2 in the flue gas, but also generate sulfides that are easy to handle. It is an efficient, stable and reliable environmental protection equipment, which is of great significance to improving environmental quality and protecting the ecological environment.

[0003] After searching, a Chinese patent with application number CN201821378522.5 discloses a blast furnace flue gas desulfurization equipment. In the traditional desulfurization process, desulfurization treatment is carried out directly without special desulfurization equipment, which makes the desulfurization process very rough and incomplete. Therefore, by setting up diversion pipes and spray heads, the flue gas in the desulfurization equipment can be sprayed comprehensively, so that the spraying range is wider, the spraying is more thorough, and the desulfurization effect is better.

[0004] During the use of the above-mentioned desulfurization equipment, it is convenient to spray the flue gas in the desulfurization equipment comprehensively. After the dust impurities generated by the spraying are filtered by the filter plate, it is not convenient to disassemble the filter plate for cleaning and maintenance because the filter plate is fixed inside the desulfurization equipment. After the filter plate has been used for a long time, more mud and dirt are likely to be generated on the surface, which affects the filtering effect. At the same time, it is easy to cause the filter plate to be corroded by mud and dirt for a long time, resulting in a reduced service life. Summary of the invention

[0043] As is known to all, flue gas desulfurization (FGD) refers to the process of removing sulfur oxides (SO2 and SO3) from flue gas or other industrial waste gas. The following is a detailed analysis of flue gas desulfurization: In FGD technology, according to the type of desulfurizer, it can be divided into the following methods: Calcium method: Based on CaCO3 (limestone), it is one of the most commonly used desulfurization methods. Limestone is abundant and relatively cheap, and the technology is mature and has high desulfurization efficiency. Magnesium method: Based on MgO, it is widely used in areas with strict flue gas control such as Japan. Magnesium desulfurization has the advantages of high desulfurization efficiency, high synchronous operation rate, rich absorbent resources, absorbable by-products and high commercial value. Sodium method: Based on Na2SO3, although it also has a certain desulfurization effect, it is less used than calcium method and magnesium method. Ammonia method: Based on NH3, ammonia is used to react with SO2 in flue gas for desulfurization. Ammonia desulfurization has the advantages of fast reaction speed and high desulfurization efficiency, but the storage and transportation of ammonia require special attention to safety. Organic alkali method: Based on organic alkali, it is a relatively new desulfurization method, and its desulfurization effect and application prospects need further research and exploration.

[0053] The present embodiment discloses a working method of a large-capacity flue gas desulfurization device, which includes a desulfurization device housing 1, a water inlet pipe 2, a mounting groove 3, a first filter plate 4, a connecting shell 5, a second filter plate 6, a columnar groove 7, a first spring 8, a push block 9, a sealing strip 10, a mounting plate 11, a threaded sleeve 12, a bolt 13, a hole groove 14, an air inlet pipe 15, a gear ring 16, a shaft 17, a gear 18, a knob 18, a fixing block 20, an outer tube 21, an inner tube 22, a second spring 23, a cleaning brush 24, a drain pipe 25, an exhaust pipe 26 and a splicing block 27, and the specific connection relationship is as shown in Example 2.

[0054] Specifically, the working method of the large-capacity flue gas desulfurization equipment includes the following steps:

[0055] After filtering with the filter plates inside the desulfurization equipment, a lot of dirt will remain on the filter plates. When the filter plates need to be disassembled, first screw the bolts 13 on both sides of the corresponding filter plates out of the hole grooves 14, so that the bolts 13 are screwed into the threaded sleeves 12, and then the mounting plate 11 is released from the fixing effect, and then the mounting plate 11 is pulled, so that the mounting plate 11 drives the corresponding first filter plate 4 and the second filter plate 6 to slide inside the mounting groove 3, so that the splicing block 27 in the second filter plate 6 is separated from the connection shell 5 in the first filter plate 4, so as to facilitate the separation of the first filter plate 4 and the second filter plate 6, and then the first filter plate 4 and the second filter plate 6 are pulled out from the inside of the two mounting grooves 3 respectively, so as to facilitate the disassembly of the filter plates.

[0056] When there are many impurities attached to the inner wall of the intake pipe 15 and it needs to be cleaned, the knob 19 is turned so that the knob 19 drives the shaft 17 to rotate. When the shaft 17 rotates, the gear 18 is driven to rotate, and the gear 18 is meshed with the ring gear 16, so that the gear 18 drives the ring gear 16 to rotate. When the ring gear 16 rotates, it drives the cleaning brush 24 to rotate under the connection action of the fixing block 20, the outer tube 21 and the inner tube 22, so as to clean the inner wall of the intake pipe 15. When the cleaning brush 24 rotates, it will vibrate, and the vibration force acts on the second spring 23, so that the second spring 23 is compressed and rebounds to generate vibration, so that the two second springs 23 drive the cleaning brush 24 to vibrate. Through the vibration, it is beneficial to improve the quality of the cleaning brush 24 for cleaning the inner wall of the intake pipe 15, thereby reducing the retention of impurities on the inner wall of the intake pipe 15.
