Abstract
Description
Technical Field
[0001] This utility model relates to the field of desulfurization island absorption tower technology, specifically a desulfurization island detection and cleaning device. Background Technology
[0002] A desulfurization island is a core process system for flue gas desulfurization in thermal power plants. It consists of equipment, buildings, and supporting subsystems. It removes acidic components such as SO2 and HCl from flue gas using chemical or physical methods, generating desulfurization products (such as gypsum) to achieve environmentally friendly emissions. The core reaction zone of the desulfurization island is the absorption tower, which completes the desulfurization reaction through contact between flue gas and slurry. During operation, the high-temperature, high-speed flue gas in the washing and concentration section often causes salts in the slurry to precipitate on the tower wall, resulting in salt buildup. Excessive salt accumulation can severely damage the equipment inside the tower, leading to system shutdown. If any desulfurization unit shuts down, according to current environmental requirements, the corresponding boiler must also be stopped, resulting in significant losses to the user's production efficiency. Therefore, after prolonged use, manual inspection is required. Once the cleaning indicators are met, the absorption tower is cleaned using a cleaning device.
[0003] However, existing cleaning devices for desulfurization island desulfurization absorption towers are usually water spraying equipment. During operation, they are mostly located at the same height to spray the interior. This creates a dead zone above the spraying device, resulting in a small cleaning area and poor cleaning effect. To address this, we propose a desulfurization island detection and cleaning device. Utility Model Content
[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a desulfurization island inspection and cleaning device. In use, the maintenance port of the desulfurization island's absorption tower is opened. Simultaneously, the angle of the rotating shaft damper is adjusted according to the position of the absorption tower's upper or lower interior. The fixing bracket is then inserted into the absorption tower, and the fixing plate is secured to ensure the bracket is horizontal. Next, water is supplied through an external water supply device connected to a water supply hose, which delivers water into the water supply hose, the annular pipe, and the installation pipe. The water is then sprayed onto the inner wall of the absorption tower through a nozzle. Simultaneously, the drive assembly is activated. The drive shaft rotates, which in turn rotates the fixed support, which in turn drives the cleaning component to work. This cleaning component cleans the inner wall of the absorption tower. The combined effect of water spraying and the cleaning component enhances the cleaning efficiency of the inner wall. Specifically, the rotation of the fixed support causes the installation pipe and annular pipe to rotate around the drive shaft. The water supply hose remains stationary due to the action of the arc-shaped plate and arc-shaped groove. Furthermore, the height or depth of the cleaning component can be adjusted via an electric push rod, thereby increasing the cleaning area of the absorption tower's inner wall and effectively solving the problems described in the background technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a desulfurization island detection and cleaning device, comprising a fixing plate, a rotating shaft damper, a fixing block, an annular pipe, a water supply hose, and cleaning components;

The motor's output shaft is connected to the lower end of a transmission shaft via a coupling, and the motor's input end is electrically connected to the output end of an external controller. The external controller controls the motor's operation, which in turn drives the transmission shaft to rotate, thus electrically completing the rotation of the transmission shaft.
[0008] Furthermore, the cleaning assembly includes pins, a cleaning brush, and a connecting slot located at the right end of the fixed bracket. A connecting block is mounted on the left side of the cleaning brush, and the connecting block and the sidewall of the connecting slot are connected by multiple pins. The connection between the connecting block and the connecting slot can be disassembled via the pin connection, thereby facilitating the maintenance and replacement of the cleaning brush.
[0009] Furthermore, the system also includes mounting blocks and mounting holes. Mounting blocks are installed on both the front and rear sides of the right end of the fixed bracket, and mounting holes are provided on the mounting blocks. The fixed bracket can be installed and disassembled using the mounting blocks and mounting holes, allowing for more stable cleaning of the absorption tower in the desulfurization island.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this desulfurization island detection and cleaning device, the maintenance port of the absorption tower of the desulfurization island is opened. Simultaneously, the angle of the rotating shaft damper is adjusted according to the upper or lower position inside the absorption tower.

The rotation of the transmission shaft drives the fixed bracket to rotate, which in turn drives the cleaning assembly to work. This cleaning assembly cleans the inner wall of the absorption tower. The cleaning effect on the inner wall of the absorption tower is improved through the water spray and the cleaning assembly. Specifically, the rotation of the fixed bracket causes the installation pipe and the annular pipe to rotate around the transmission shaft. Under the action of the arc plate and arc groove, the water supply hose remains stationary. Furthermore, the height or depth of the cleaning assembly can be adjusted via an electric push rod, thereby increasing the cleaning area of the inner wall of the absorption tower.

The water supply hose 6 passes through the locking holes of the first support block 12 and the second support block 19.
[0017] During use, open the maintenance port of the desulfurization island's absorption tower. Simultaneously, adjust the angle of the rotating shaft damper 11 according to the position of the upper or lower part of the absorption tower's interior. Insert the fixed bracket 22 into the absorption tower, and then fix the fixed plate 1 to ensure the fixed bracket 22 is in a horizontal position. Next, supply water through an external water supply device connected to the water supply hose 6, sending water into the water supply hose 6, the annular pipe 4, and the installation pipe 3. Spray the water onto the inner wall of the absorption tower through the nozzle 2. Simultaneously, start the drive assembly to drive the transmission shaft 7 to rotate. The rotation of shaft 7 drives the fixed bracket 22 to rotate, which in turn drives the cleaning component to work. This cleaning component cleans the inner wall of the absorption tower. The cleaning effect on the inner wall of the absorption tower is improved by the water spray and the cleaning component. Specifically, the rotation of fixed bracket 22 drives the installation pipe 3 and the annular pipe 4 to rotate around the drive shaft 7.

Next, water is supplied through an external water supply device connected to the water supply hose 6, sending water into the water supply hose 6, the annular pipe 4, and the installation pipe 3. The water is then sprayed onto the inner wall of the absorption tower through the nozzle 2. Simultaneously, the drive assembly is activated.

The water supply hose 6 remains stationary due to the action of the arc plate 5 and the arc groove. Furthermore, the height or depth of the cleaning assembly can be adjusted using the electric push rod 9, increasing the cleaning area of the absorption tower's inner wall. An external controller controls the motor 21, which in turn drives the drive shaft 7 to rotate electrically. The connection between the connecting block 13 and the connecting groove can be disassembled via the pin 14, facilitating maintenance and replacement of the cleaning brush 15. The fixed bracket 22 can be installed and removed via the mounting block 18 and mounting hole 20, ensuring more stable cleaning of the desulfurization island's absorption tower.
