Description

Technical Field

[0001] The utility model belongs to the technical field of desulfurization dust collectors, and in particular relates to a multi-stage partition type desulfurization dust collector. Background Art

[0002] The desulfurization dust collector converts SO2 in the flue gas into sulfate or other forms through chemical absorption or physical adsorption, thereby reducing pollution to the environment. It can not only effectively remove sulfur oxides and particulate matter in the flue gas to achieve the purpose of purifying the flue gas, but also help reduce the formation of acid rain.

[0003] At present, the technologies required for desulfurization and dust removal mainly involve the following aspects:

[0004] 1. Desulfurization technology: One of the core functions of a desulfurization dust collector is desulfurization, which is to remove sulfur dioxide (SO2) from flue gas. The main desulfurization technologies include wet desulfurization, dry desulfurization, and semi-dry desulfurization;

[0005] 2. Dust removal technology: Dust removal is another important function of desulfurization dust collector. Dust removal technologies mainly include filtration dust removal, electrostatic precipitator and wet dust removal;

[0006] 3. Flue gas pretreatment technology: before desulfurization and dust removal, the flue gas is pretreated, such as cooling and dust removal, to improve the desulfurization and dust removal effect;

[0007] 4. Anti-corrosion technology. Since the desulfurization dust collector will be exposed to corrosive substances during operation, corresponding anti-corrosion measures need to be taken, such as using corrosion-resistant materials and applying anti-corrosion coatings.

[0008] At present, manufacturers generally have two designs for desulfurization and dust removal equipment. One is the combination of desulfurization equipment and dust removal equipment, and the other is a separate desulfurization equipment. Separate desulfurization equipment, such as wet desulfurization equipment, is equipped with a spray system inside the wet desulfurization equipment. The system atomizes the alkaline solution (such as calcium hydroxide or sodium carbonate) into fine droplets through a nozzle and sprays it evenly on the flue gas. The alkaline substances in the spray liquid react with the sulfur dioxide in the flue gas to generate sulfates or sulfites, which dissolve in the spray liquid. This step not only achieves desulfurization, but also helps to remove dust. The wet desulfurization equipment contains multiple grid partitions, and fillers are placed on the upper surface of the grid partitions. The fillers increase the gas-liquid contact area inside the desulfurization tower. When the flue gas passes through the filler layer, due to the shape, size and arrangement of the filler, the flue gas is divided into many fine airflows. At the same time, the spray liquid is also dispersed into fine droplets. The gas-liquid two phases are fully contacted in the filler layer, thereby improving the desulfurization efficiency.

[0009] However, there is a problem with the above-mentioned equipment. When a large amount of dust and impurities contained in the flue gas enters the interior of the equipment, it is easy to have an adverse effect on the structure of the equipment. For example, large impurities are easy to deposit on the surface of the filler, forming a blockage, reducing the ventilation performance of the filler, and reducing the desulfurization efficiency. At the same time, impurities are easy to clog the nozzle of the spray pipe, resulting in the spray liquid being unable to be sprayed evenly, reducing the desulfurization efficiency, and impurities will cause erosion and wear on the inner wall of the spray pipe when flowing at high speed, shortening the service life of the pipeline. In response to this problem, this application proposes a solution to add a filtering mechanism in the air inlet pipe to block large particles of dust and impurities in the flue gas when they enter the equipment, reducing the risk of blockage during the desulfurization process, and improving the desulfurization efficiency and the service life of the equipment. Utility Model Content

[0012] A limit plate is fixedly installed inside the installation cylinder, a circular groove is opened on the outside of the limit plate, and one end of the threaded rod close to the filter plate is movably connected to the inside of the circular groove.

[0013] Preferably, an insert plate is provided inside the mounting cylinder, and the insert plate is located at one end of the mounting cylinder close to the filter plate.

[0014] Preferably, a slot is provided inside the installation tube, and the inserting plate is snapped into the slot.

By setting up the installation cylinder and matching the filter plate 1, when the air inlet pipe is connected to other pipes, first slide the filter plate 1, filter plate 2 and filter plate 3 one by one to the outside of the threaded rod and fix them by rotating the disk.

At this time, the three filter plates are blocked by the plug plate and the limit plate to prevent the three filter plates from detaching from the inside of the installation cylinder, so that the user can take out the three filter plates together with the installation cylinder when cleaning the filter plates, thereby improving work efficiency.

At this time, the installation cylinder 3 is inserted into the interior of the air inlet pipe 1 until the installation cylinder 3 is blocked by the limit block 2.
