Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of desulfurization and denitrification tower demister, in particular to a desulfurization and denitrification tower demister convenient to clean. BACKGROUND

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

[0003] The centrifugal demister is a common desulfurization and denitrification tower demister. The centrifugal demister uses centrifugal force to separate mist droplets. When the flue gas with mist droplets enters the demister, the flue gas is guided by the rotating blades to produce rotational motion. The mist droplets are thrown to the wall of the demister during rotation due to the large mass and large centrifugal force, and then form larger droplets at the wall, which 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, slurry, particulate matter and other impurities in the flue gas are easily deposited on the surface of the blades and in the gap between the blades to form a scale layer. These scale layers will gradually thicken over time. Due to the narrow channel between the blades, the cleaning liquid cannot fully contact the lower surface of the centrifugal blades when the centrifugal demister is cleaned, which affects the complete cleaning of the scale layer on the centrifugal blades. Therefore, we propose a desulfurization and denitrification tower demister convenient to clean. SUMMARY

[0005] The present application aims to provide a desulfurization and denitrification tower demister convenient to clean to solve the problems raised in the background.

[0050] In the scheme: a desulfurization and denitrification tower demister convenient to clean, comprising the following steps:

[0051] In the process of demisting the flue gas generated in the desulfurization and denitrification tower, the mounting ring 102 at the upper end of the cylindrical shell 101 is installed and fixed in the interior of the desulfurization and denitrification tower by means of bolts, after installation, the flue gas to be treated passes through the demister, in the process of passing through, the flue gas is guided to rotate by the centrifugal blades 104 fixed between the mounting cylinder 103 and the rotating cylinder 2, the mist droplets are thrown to the wall surface of the rotating cylinder 2 in the rotating process due to the large mass and the large centrifugal force, and the mist droplets are gathered into larger droplets at the wall surface, and then fall down under the action of gravity, realizing gas-liquid separation;

[0052] In the process of operation of the centrifugal mist eliminator, slurry, particulate matter and other impurities in the flue gas are likely to deposit on the lower surface of the centrifugal blade 104 to form a scale layer, and the centrifugal blade 104 needs to be cleaned. In the cleaning process, the rotating assembly and the driving assembly cooperate with each other to drive the rotating cylinder 2 to rotate under stress. In the process of rotation of the rotating cylinder 2, the groups of centrifugal blades 104 are driven to rotate synchronously. In the process of rotation of the centrifugal blades 104, the strip-shaped water tank 501 below the centrifugal blades 104 moves under the action of centrifugal force. In the process of movement of the strip-shaped water tank 501, the connecting block 601 and the circular rod 602 guide the sliding of the strip-shaped water tank 501 under stress, so that the strip-shaped water tank 501 moves along the trajectory below the centrifugal blades 104 under stress. In the process of movement of the strip-shaped water tank 501, the rotating assembly and the driving assembly adjust the rotation speed of the centrifugal blades 104, so that the strip-shaped water tank 501 can move at different centrifugal forces. In combination with the reset pushing action of the connecting spring 603 on the sliding assembly, the strip-shaped water tank 501 can reciprocate under stress below the centrifugal blades 104.

[0053] In the process of reciprocating movement of the strip-shaped water tank 501, the pipeline outside the conveying cleaning liquid is connected with the end of the liquid supply pipe 1004 on the U-shaped frame 1003. Through the connection of the pipeline and the liquid supply pipe 1004, the external cleaning liquid is supplied to the inside of the liquid storage cavity 1001. In the process of liquid supply, the connecting hose 702 and the installation pipe 701 are communicated and transported, and the pressure of the cleaning liquid in the liquid storage cavity 1001 drives the transported cleaning liquid to move to the inside of the strip-shaped water tank 501 and be sprayed to the surface of the centrifugal blade 104 through the fan-shaped nozzles 502. Through the spraying of the cleaning liquid and the reciprocating movement of the strip-shaped water tank 501 along the trajectory below the centrifugal blade 104, the cleaning liquid can fully contact different positions below the centrifugal blade 104, so as to facilitate the thorough cleaning operation of the scale layer formed on the lower surface of the centrifugal blade 104. In the process of reciprocating movement of the centrifugal blade 104, the elastic assembly drives the scraper 1102 to move with the strip-shaped water tank 501 and abut against the lower surface of the centrifugal blade 104. Through the abutment, extrusion and relative sliding between the scraper 1102 and the lower surface of the centrifugal blade 104, the scale and foreign matter on the lower surface of the centrifugal blade 104 after spraying the cleaning liquid are scraped and separated, which further ensures the cleaning effect of the centrifugal blade 104.
