Description

Technical Field

[0001] This invention belongs to the field of cleaning technology, and specifically relates to a safe unclogging device for dust removal chambers. Background Technology

[0002] Desulfurization ash: Flue gas desulfurization and dust removal are achieved through a dry desulfurization + bag filter dust collection process. After desulfurization, the solid particles contained in the flue gas are collected by the filter bags in the bag filter and fall into the bottom hopper of the dust collection bin. The mixture containing desulfurizing agent, desulfurization reaction products and flue dust is called desulfurization ash.

[0003] Currently, the desulfurization and denitrification system for coke oven flue gas mainly adopts a dry desulfurization + bag filter + SCR denitrification process. In the bag filter system, the desulfurization ash collected falls to the bottom of the hopper under the action of pulse backflushing of the filter bags. As the accumulated desulfurization ash thickness gradually increases, the temperature of the ash adhering to the bottom and side walls of the hopper gradually decreases, especially at the discharge port, where it easily drops below the dew point. Under the conditions of high flue gas humidity and the tendency of desulfurization ash (containing sodium bicarbonate) to clump, this gradually clogs the bottom of the hopper. This not only affects the normal operation of the ash conveying system but also causes serious problems such as filter bag detachment due to material accumulation in the dust collection hopper, increased outlet dust levels, and spontaneous combustion accidents caused by heat accumulation of desulfurization ash.

[0004] A search revealed that patent application number 201510159090.3 discloses a vertical coal bunker unblocking device and method, belonging to the technical field of coal mine auxiliary equipment. The device includes a winch, steel pipe, steel bar, pulleys, a movable hinge support, and a wire rope. The steel pipe is cast into the outer wall of the coal bunker, and the steel bar can move up and down inside the pipe. When the coal bunker becomes blocked, the pulleys and wire rope allow the steel bar to move downwards inside the pipe, clearing the blocked coal. After the blockage is cleared, the pulleys and wire rope allow the steel bar to move upwards inside the pipe, returning the device to its original position. This vertical coal bunker unblocking device has a simple structure, good unblocking effect, high efficiency, is not easily limited by site conditions, saves time in handling accidents, and promotes safe and efficient coal mine production.

[0005] Currently, the main automatic unclogging methods for dust collection chambers are vibration unclogging, air cannon unclogging, air disc unclogging, and combinations of the above two methods. When the bottom of the dust collection chamber is blocked due to moisture, caking, or arching, the automatic unclogging methods described in the above documents cannot solve the problem of blockage caused by moisture, caking, or arching at the bottom of the dust collection chamber. Therefore, a safe unclogging device for dust collection chambers has been designed. Summary of the Invention

This gap is designed to avoid interference between the sliding frame and the fixed frame during operation.

[0023] 6) The sliding frame of this device can drive the first rotating arm and the second rotating arm to rotate around the first rotating shaft and the second rotating shaft respectively, thereby driving the unblocking rod to move up and down to achieve the purpose of unblocking the dust collection chamber, ensuring the cleanliness of the dust collection chamber and the normal operation of the dust collection chamber.

[0024] 7) The guide rod of this device is used to guide the sliding plate and sliding column to move up and down, prevent the sliding plate from shaking during the sliding process, and ensure the stability and safety of the sliding plate and sliding column during the up and down movement.

[0025] 8) The crossbar and tilt bar of this device are used to support the scraper frame, ensuring that the scraper frame is always in a stable state during operation. When the unblocking rod moves up and down, it can drive the scraper frame to move up and down, thereby scraping away impurities on the inner wall of the dust removal chamber and ensuring the cleanliness of the inner wall of the dust removal chamber.

[0026] 9) The mounting plate of this device is used to install the first sealing plate and the second sealing plate, ensuring that the first sealing plate and the second sealing plate can seal the first clearance hole on the dust removal chamber, preventing the gas in the dust removal chamber from flowing out of the first clearance hole, thus ensuring the safety of the personnel. The spring provides power for the first sealing plate to move to the second sealing plate, ensuring that the first sealing plate and the second sealing plate are always in contact with the first rotating arm or the second rotating arm, thus ensuring the sealing quality of the first clearance hole by the first sealing plate and the second sealing plate.

[0027] 10) The second guide post of this device is used to guide the up and down movement of the first sealing plate. At the same time, the second guide post can also limit the first sealing plate to prevent it from shaking during operation, thereby improving the sealing effect of the first and second sealing plates on the first clearance hole.
