Description

Technical Field

[0001] The utility model relates to the field of desulfurization towers, in particular to a spray observation device in a desulfurization tower. Background Art

[0002] For environmental protection needs, the flue gas from the boiler of the waste heat power generation device needs to be desulfurized, and most of them use an ammonia desulfurization device. In the boiler flue gas desulfurization system, the flue gas containing sulfur dioxide enters the desulfurization tower through the inlet baffle door, and the high-temperature flue gas enters the concentration section in the middle of the desulfurization tower. After spraying dust removal and humidification, the temperature drops to 50-60℃, and then enters the upper absorption section. After the sulfur dioxide in the flue gas is absorbed, it enters the top demisting section and becomes purified flue gas. When it leaves the desulfurization tower, the temperature of the clean flue gas is 50-60℃ and it is discharged into the chimney.

[0003] Traditionally designed desulfurization towers are all closed and only have manholes, which are mainly used for maintenance and cleaning to facilitate workers to enter during maintenance and cleaning. Due to the closed structure of the desulfurization tower, the spraying operation status in the desulfurization tower cannot be understood in real time, which often leads to missed inspections and repairs, and equipment accidents caused by misjudgment occur from time to time.

[0004] At present, an observation window is usually installed on the outside of the desulfurization tower to realize the real-time understanding of the spraying situation inside the desulfurization tower. However, after long-term use, the inside of the observation window is more likely to be stained, resulting in the overall blurring of the observation window, which reduces the clarity of the observation through the observation window and easily affects the real-time acquisition of the spraying situation inside the desulfurization tower.

[0025] See also Figure 3The rotating assembly 56 in this embodiment includes a driving rod 561 built into the supporting column 52 for realizing rotation transmission, and a pull rope 562 correspondingly wound around the outer side of the lower end of the driving rod 561. By pulling the pull rope 562, the driving rod 561 can be easily rotated and transmitted. A main bevel gear 563 connected to the upper end of the driving rod 561, a secondary bevel gear 564 meshingly connected to the upper end of the main bevel gear 563, and a connecting shaft 565 vertically inserted into the top of the driving rod 561 for connection and cooperation, and the upper end of the connecting shaft 565 is inserted into the upper end of the top shell 53, and a spring 566 connected to the upper end of the connecting shaft 565 and connected to the upper end of the top shell 53 is connected. Through the elasticity of the spring 566, the driving rod 561 can be automatically rotated and transmitted.

[0026] Among them, the driving rod 561 is vertically installed inside the supporting column 52, and the lower end of the driving rod 561 is rotatably connected to the inside of the connecting shell 51, so as to ensure the stability of the overall rotation transmission process of the driving rod 561; the front side of the pull rope 562 extends to the outside of the connecting shell 51, and the front side of the pull rope 562 is integrally equipped with a pull ring, so as to ensure that the pull rope 562 can realize convenient pulling activities through the pull ring provided on the front side; the secondary bevel gear 564 is meshed with the upper end of the front side of the main bevel gear 563, and the middle part of the front side of the secondary bevel gear 564 is connected to the rotating shaft 54, so as to ensure that the secondary bevel gear 564 is stably meshed and connected with the main bevel gear 563, so as to realize the smooth rotation and drive of the rotating shaft 54.

[0027] See also Figure 4 The connecting assembly 57 in this embodiment includes an upper clamping strip 571 correspondingly and longitudinally fixedly connected to both sides of the outer end of the connecting shell 51, a lower clamping strip 572 correspondingly and longitudinally fixedly connected to both sides of the outer end of the connecting shell 51, and there is a gap between the upper clamping strip 571 and the lower clamping strip 572, spring sheets 573 respectively installed inside the upper clamping strip 571 and the lower clamping strip 572, and the spring sheets 573 on both sides are close to each other, and the spring sheets 573 on both sides are installed and arranged in opposite states, a fixing strip 574 correspondingly and longitudinally embedded in the gap between the upper clamping strip 571 and the lower clamping strip 572, guide openings 575 symmetrically opened at the upper and lower ends of the front side of the fixing strip 574, and the guide openings 575 on both sides are opened in a smooth and inclined state, and slots 576 symmetrically and longitudinally opened at the upper and lower ends of the fixing strip 574, and the slots 576 on both sides can be correspondingly engaged and locked with the spring sheets 573 inside the upper clamping strip 571 and the lower clamping strip 572.

[0028] Specifically, the upper clamping strip 571 and the lower clamping strip 572 are symmetrically arranged along the left and right sides of the connecting shell 51, and the upper clamping strip 571 and the lower clamping strip 572 are installed correspondingly up and down, ensuring that the upper clamping strip 571 and the lower clamping strip 572 on both sides can be quickly connected and combined; the fixing strip 574 is longitudinally placed between the upper clamping strip 571 and the lower clamping strip 572, and the fixing strip 574 is fixedly connected to the lower end of the connecting seat 1, ensuring that the fixing strip 574 can be accurately connected with the upper clamping strip 571 and the lower clamping strip 572, ensuring the rapid disassembly of the convenient cleaning device 5 as a whole.

[0029] Here’s how it works:

[0030] When the observation device is to be used, the bolts 3 provided at the four corners of the outer side of the connection seat 1 can be connected to the external installation position of the desulfurization tower body 4, so that the observation window body 2 provided in the middle of the connection seat 1 can be installed and used. Therefore, the real-time acquisition of the spraying status inside the desulfurization tower can be realized conveniently through the observation window body 2, so as to avoid the difficulty in discovering the abnormal spraying, which may affect the desulfurization effect.

[0031] Secondly, in order to ensure that the stains attached to the inner side of the observation window body 2 can be easily cleaned after long-term use, a convenient cleaning device 5 is provided inside the connecting seat 1. That is, when cleaning is required, the pull ring integrally connected to the outside of the pull rope 562 can be pulled out by pulling the pull ring to pull out the pull rope 562 as a whole. As the pull rope 562 is pulled out, the driving rod 561 installed inside the supporting column 52 will realize rotational movement accordingly. When the driving rod 561 rotates, the main bevel gear 563 installed on the top of the driving rod 561 will realize the meshing transmission of the secondary bevel gear 564 provided on the upper front side, so that the secondary bevel gear 564 rotates as a whole. In this way, the rotating shaft 54 ​​connected to the middle part of the front side of the secondary bevel gear 564 will realize the rotation drive of the externally connected scraper strip 55, so that the scraper strip 55 rotates in a circle to cooperate with the cleaning cotton provided inside to scrape and clean the stains attached to the inner side of the observation window body 2.

[0032] At the same time, when the driving rod 561 rotates, the top plug-in connecting shaft 565 will be driven synchronously, so that the connecting shaft 565 can realize the contraction transmission of the spring 566 connected to the upper end. Therefore, when the pull ring is released, the compressed spring 566 will realize the automatic rotation of the driving rod 561, so that the scraper 55 can rotate in the opposite direction to automatically scrape and clean the inner side of the observation window body 2. At the same time, the pulled out pull rope 562 will automatically rewind back to the lower end of the driving rod 561 to complete the subsequent pulling drive preparation activity, and then, through the pulling and rotating cooperation of the pull rope 562 and the spring 566, the scraper bar 55 can be conveniently and smoothly driven to rotate, so that the scraper bar 55 can efficiently scrape and clean the stains attached to the inner side of the observation window body 2, thereby achieving the advantage of convenient and smooth scraping and cleaning of the stains attached to the inner side of the observation window body 2.

[0033] If the scraper strip 55 needs to be disassembled and replaced later, the connection shell 51 can be pulled as a whole after the disassembly of the connection seat 1 is completed, so that the upper clamping strip 571 and the lower clamping strip 572 symmetrically arranged on the left and right sides of the connection shell 51 are separated from the fixed strip 574 that is clamped therebetween, so that the spring piece 573 correspondingly embedded in the clamping groove 576 on the upper and lower sides of the fixed strip 574 can be easily moved out, and then the convenient cleaning device 5 can be conveniently taken out from the lower end of the connection seat 1 as a whole, so as to realize the convenient disassembly of the scraper strip 55 as a whole;

[0034] When the convenient cleaning device 5 is reinstalled and used, the connecting shell 51 needs to be reinserted into the lower end of the connecting seat 1, and the upper clamping strip 571 and the lower clamping strip 572 are respectively in contact with the upper and lower sides of the fixing strip 574. During the insertion process of the connecting shell 51, the fixing strip 574 will cooperate with the guide openings 575 set at the upper and lower ends of the front side, and the spring sheets 573 set on the inner sides of the upper clamping strip 571 and the lower clamping strip 572 can be squeezed at the same time. When the spring sheets 573 on both sides move to the clamping grooves 576 opened at the upper and lower ends of the fixing strip 574, the compressed spring sheets 573 on both sides will rebound quickly to automatically snap into the corresponding clamping grooves 576, thereby realizing the elastic clamping and locking of the upper and lower clamping strips 571 and the fixing strips 574. In this way, the connecting shell 51 and the middle part of the lower end of the connecting seat 1 can be re-connected, so that the convenient cleaning device 5 can complete the convenient installation activity, thereby achieving the advantage of convenient disassembly and assembly of the convenient cleaning device 5 and the connecting seat 1.

[0035] The utility model provides a desulfurization tower internal spray observation device, which is provided with a convenient cleaning device 5, that is, by pulling down through a pull rope 562, a driving rod 561 can realize the meshing transmission of a main bevel gear 563 and a secondary bevel gear 564, so that the rotating shaft 54 ​​indirectly drives a scraper bar 55 to scrape and clean the inner side of an observation window body 2, and in conjunction with a connecting shaft 565 and a spring spring 566, the driving rod 561 can automatically rotate to automatically wind up the pull rope 562, thereby achieving the advantage of convenient scraping and cleaning of the inner side of the observation window body 2, and a connecting component 57 is provided, that is, a spring sheet 573 arranged inside an upper clamping bar 571 and a lower clamping bar 572, which can be correspondingly engaged with a clamping groove 576 opened on the upper and lower sides of a fixing bar 574, thereby achieving a stable and convenient docking combination of a connecting seat 1 and the convenient cleaning device 5, and at the same time, the connecting shell 51 can be directly pulled to realize a quick-release activity, thereby achieving the advantage of convenient assembly and disassembly of the convenient cleaning device 5 and the connecting seat 1.
