Description

Technical Field

[0001] The invention relates to the technical field of desulfurization and denitration tower demisters, in particular to a desulfurization and denitration tower demister which is easy to clean. Background Art

[0002] In the desulfurization and denitrification process, the absorption tower absorbs sulfur dioxide and nitrogen oxides in the flue gas by spraying slurry, which will cause the flue gas to carry a large number of droplets. If these droplets are not removed, they will be discharged with the flue gas. The demister can effectively separate these droplets from the flue gas. For example, in the limestone-gypsum wet flue gas desulfurization process, the sprayed limestone slurry will form droplets containing gypsum particles after absorbing sulfur dioxide. The demister can intercept these droplets and prevent them from entering the chimney with the flue gas, thereby avoiding the "gypsum rain" phenomenon.

[0003] The centrifugal demister is a common type of demister for desulfurization and denitrification towers. The centrifugal demister uses centrifugal force to separate droplets. When the flue gas with droplets enters the demister, the flue gas produces a rotational motion through the guidance of the rotating blades. During the rotation, the droplets are subjected to a large centrifugal force due to their large mass, and are thus thrown to the wall of the demister. At the wall, the droplets gather into larger droplets, and then fall under the action of gravity to achieve gas-liquid separation.

[0004] The space between the rotating blades of the centrifugal demister is relatively narrow. During operation, impurities such as slurry and particulate matter in the flue gas are easily deposited on the blade surface and the gaps between the blades to form scale layers. These scale layers will gradually thicken over time. Due to the narrow channels between the blades, when the centrifugal demister is cleaned by cleaning, the cleaning liquid cannot fully contact the lower surface of the centrifugal blades, affecting the thorough cleaning of the scale layer on the centrifugal blades. For this reason, we propose a desulfurization and denitrification tower demister that is easy to clean. Summary of the invention

[0050] In this scheme: a desulfurization and denitration tower demister that is easy to clean includes the following steps:

[0051] In the process of demisting the flue gas generated inside the desulfurization and denitration tower, the mounting ring 102 at the upper end of the cylindrical shell 101 is fixed to the inside of the desulfurization and denitration tower by bolts. After the installation is completed, the flue gas to be treated passes through the demister. During the passing process, the transported flue gas is guided by multiple groups of centrifugal blades 104 fixed between the mounting cylinder 103 and the rotating cylinder 2, so that the transported flue gas generates a rotational motion. During the rotation process, the droplets are subjected to a large centrifugal force due to their large mass, and are thus thrown to the wall of the rotating cylinder 2. At the wall, the droplets gather into larger droplets, and then fall under the action of gravity to achieve gas-liquid separation.

[0052] During the operation of the centrifugal demister, impurities such as slurry and particulate matter in the flue gas are easily deposited on the lower surface of the centrifugal blades 104 to form a scale layer, and the centrifugal blades 104 need to be cleaned. During the cleaning process, the rotating drum 2 is driven to rotate by the cooperation of the rotating assembly and the driving assembly. During the rotation of the rotating drum 2, each group of centrifugal blades 104 is driven to rotate synchronously. During the rotation of the centrifugal blades 104, the strip water tank 501 below the centrifugal blades 104 is forced to move by the action of centrifugal force. During the movement of the strip water tank 501, During the process, the connecting block 601 and the round rod 602 slide and guide the strip water tank 501 after being stressed, so that the strip water tank 501 is forced to move along the trajectory below the centrifugal blade 104. During the movement of the strip water tank 501, the rotating assembly and the driving assembly adjust the rotation speed of the centrifugal blade 104, so that the strip water tank 501 can move with different centrifugal forces, and the connection spring 603 on the sliding assembly pushes the strip water tank 501 after movement to reset, so that the strip water tank 501 can be forced to reciprocate below the centrifugal blade 104;

[0053] During the reciprocating motion of the strip water tank 501, the pipeline for conveying the cleaning liquid outside is connected to the end of the liquid supply pipe 1004 on the U-shaped frame 1003. Through the connection between the pipeline and the liquid supply pipe 1004, the external cleaning liquid is supplied to the inside of the liquid storage chamber 1001. During the liquid supply process, through the communication and conveying action of the connecting hose 702 and the mounting pipe 701 and the pressure action of the cleaning liquid inside the liquid storage chamber 1001, the conveyed cleaning liquid moves to the inside of the strip water tank 501 and is sprayed toward the surface of the centrifugal blade 104 through each group of fan-shaped nozzles 502. Through the spraying of the cleaning liquid and the strip water tank 501 along the centrifugal blade 1 The reciprocating motion of the trajectory below the centrifugal blade 104 enables the cleaning liquid to fully contact different positions below the centrifugal blade 104, which is convenient for the thorough cleaning of the scale layer formed on the lower surface of the centrifugal blade 104, and in the process of the centrifugal blade 104 being forced to reciprocate, the scraper 1102 is pushed by the elastic component to keep against the lower surface of the centrifugal blade 104 along with the movement of the strip water tank 501, and the scraper 1102 and the lower surface of the centrifugal blade 104 are pressed against and relative to each other and slide relative to each other, The scale layer and foreign matter on the lower surface of the centrifugal blade 104 after the cleaning liquid is sprayed are scraped and separated, thereby further ensuring the cleaning effect of the centrifugal blade 104.
