Description

Technical Field

[0001] The present invention relates to the technical field of flue gas desulfurization devices, and specifically to an absorption tower system for flue gas desulfurization in a cement kiln. Background Technique

[0002] The commonly used method for flue gas desulfurization in a cement kiln is to use an absorption tower for gas scrubbing and desulfurization. The working process of the absorption tower for flue gas desulfurization in a cement kiln is as follows: 1. Flue gas enters the absorption tower: After the flue gas is generated from the cement kiln, most of the particulate matter and dust are removed by the dust removal equipment and then enter the absorption tower. 2. Absorbent liquid spraying: The absorbent liquid is evenly sprayed through nozzles to form droplets at the top of the absorption tower. The flue gas enters the absorption tower through the bottom nozzles and contacts the droplets. 3. SO2 absorption: SO2 in the flue gas will react chemically with calcium hydroxide in the absorbent liquid to generate calcium sulfate and water. This reaction is an endothermic reaction, so heat needs to be provided. 4. Collection of reaction products: The reaction products generated are collected by the collector at the bottom of the absorption tower, mainly calcium sulfate. 5. Recirculation of the absorbent liquid: The collected reaction products can be sprayed again by the nozzles into the absorption tower for recycling after being processed, which can improve the absorption efficiency and reduce the consumption of the absorbent liquid. 6. Discharge of desulfurized flue gas: Most of the SO2 in the flue gas after being treated by the absorption tower has been absorbed and removed by the absorbent liquid, reducing environmental pollution.

[0003] After the flue gas is treated by the dust removal equipment, the particulate matter and dust will adsorb on the dust removal equipment. Since the dust removal equipment is installed inside the absorption tower, during operation, even if too much particulate matter and dust adsorb on the dust removal equipment, resulting in a deterioration of the dust removal effect, at this time, it is impossible to clean the particulate matter and dust on the dust removal equipment in time, and it can only be cleaned after shutting down and disassembling the machine shell.

Specific embodiments

[0032] Please refer to Figures 1-8 , the present invention provides a technical solution: an absorption tower system for desulfurizing cement kiln flue gas, including an absorption tower 1, characterized in that: the specific desulfurization steps are as follows:

[0033] Step 1: When the smoke inlet pipe 2 of the absorption tower 1 admits gas, the gas blows the driving assembly 3 to rotate. At this time, the driving assembly 3 drives the unclogging assembly 4 to clean the impurities adsorbed on the dust removal equipment 6;

[0034] Step 2: During the reciprocating movement of the unclogging assembly 4, the unclogging assembly 4 unclogs the impurities in the holes of the dust removal equipment 6, so that the subsequent incoming gas can be continuously purified;

[0035] Step 3: When the unclogging assembly 4 moves, the unclogging assembly 4 drives the cleaning assembly 5 to move synchronously, and the cleaning assembly 5 centrally collects the impurities cleaned in the holes of the dust removal equipment 6;

[0036] As a further solution of the present invention, a smoke inlet pipe 2 is provided at the front of the absorption tower 1. A driving assembly 3 is provided at the front of the smoke inlet pipe 2. The driving assembly 3 is used to generate power by using gas. A dredging assembly 4 is provided at the rear of the driving assembly 3. The dredging assembly 4 is used for impurity cleaning. A dust removal device 6 is provided on the inner wall of the smoke inlet pipe 2. A cleaning assembly 5 is provided above the dredging assembly 4. The cleaning assembly 5 is used to collect impurities centrally;

[0037] When the flue gas enters the smoke inlet pipe 2 provided at the front of the absorption tower 1, the continuous gas will push the driving assembly 3 to rotate. At this time, the rotation of the driving assembly 3 will drive the dredging assembly 4 to perform reciprocating movements. The dredging assembly 4 cleans the impurities adsorbed on the dust removal device 6. During the reciprocating movement of the dredging assembly 4, the dredging assembly 4 will dredge the impurities in the holes of the dust removal device 6, so that the subsequent incoming gas can be continuously purified. When the dredging assembly 4 moves, the dredging assembly 4 will drive the cleaning assembly 5 to move synchronously. The cleaning assembly 5 will collect the impurities cleaned from the holes of the dust removal device 6 centrally, avoiding the impurities falling into the interior of the absorption tower 1 after being scattered due to lack of centralized collection, which affects the subsequent desulfurization treatment.

[0038] As a further solution of the present invention, the driving assembly 3 includes: a driving blade 31, a first bevel gear rod 311, a second bevel gear rod 32, an arc-shaped frame 321, a support frame 33, and a steering shaft member 34. The middle of the driving blade 31 is fixedly connected to the rod body of the first bevel gear rod 311. The end of the first bevel gear rod 311 is rotatably connected to the inner wall of the smoke inlet pipe 2. The first bevel gear rod 311 is meshed with the second bevel gear rod 32. The rod body of the second bevel gear rod 32 passes through and is rotatably connected to the upper part of the support frame 33. The lower end of the support frame 33 is fixedly connected to the inner wall of the smoke inlet pipe 2. The end of the second bevel gear rod 32 is fixedly connected to one end of the arc-shaped frame 321. The other end of the arc-shaped frame 321 is rotatably connected to the middle of the steering shaft member 34. The end of the steering shaft member 34 is rotatably connected to the inner wall of the smoke inlet pipe 2. The rear of the support frame 33 is fixedly connected to the dredging assembly 4;

[0039] The steering shaft member 34 further includes: a double-head frame 341 and a rotating column 342. The middle of the steering shaft member 34 is rotatably connected to the end of the double-head frame 341. The middle of the double-head frame 341 is rotatably connected to one end of the rotating column 342. The other end of the rotating column 342 is fixedly connected to the end of the arc-shaped frame 321;

[0040] When a continuous stream of gas drives the driving blade 31 to rotate, the bevel gear rod 311 fixedly connected to the driving blade 31 will also rotate synchronously. Since the bevel gear rod 311 is meshed with the bevel gear rod 32, the bevel gear rod 311 will drive the bevel gear rod 32 to rotate. At this time, the bevel gear rod 32 drives the arc-shaped frame 321 to rotate synchronously. Since the rotating column 342 can rotate, when the arc-shaped frame 321 rotates, it will drive the double-headed frame 341 to perform a reciprocating swinging motion through the rotating column 342. And the double-headed frame 341 is also rotatably connected to the shaft in the middle of the steering shaft member 34, so the steering shaft member 34 will also swing reciprocally, so that the driving assembly 3 drives the dredging assembly 4 to swing reciprocally, so that the dredging assembly 4 can dredge the impurities adsorbed in the holes of the dust removal device 6.

[0041] By the way that the continuously incoming gas drives the driving assembly 3 to operate, so that the driving assembly 3 can drive the dredging assembly 4 to clean the dust removal device 6, the holes of the dust removal device 6 can be cleaned in a state of occupying less space, avoiding affecting the purification of impurities in the gas by the dust removal device 6.

[0042] As a further solution of the present invention, the dredging assembly 4 includes: an elastic adaptive member 41, a sliding arm 411, a first spring 412, and a dredging roller 42. The end of the elastic adaptive member 41 is fixedly connected to the rear of the steering shaft member 34. The groove of the elastic adaptive member 41 is slidably connected to the rod body of the sliding arm 411. One end of the sliding arm 411 is fixedly connected to one end of the first spring 412. The other end of the first spring 412 is fixedly connected to the inner wall of the elastic adaptive member 41. The other end of the sliding arm 411 is rotatably connected to the middle of the dredging roller 42;

[0043] The dredging roller 42 further includes: a dredging column 421 and a linkage handle 422. A plurality of dredging columns 421 are arranged on the outer wall of the dredging roller 42. The upper part of the dredging roller 42 is rotatably connected to one end of the linkage handle 422. The other end of the linkage handle 422 is rotatably connected to the cleaning assembly 5;

[0044] When the double-headed frame 341 drives the steering shaft member 34 to swing reciprocally, since the rear part of the steering shaft member 34 is fixedly connected to the elastic adaptive member 41, the inner groove of the elastic adaptive member 41 is slidably connected to the sliding arm 411, and the sliding arm 411 penetrates and rotatably connects to the dredging roller 42. Therefore, when the sliding arm 411 drives the dredging roller 42 to move, the dredging column 421 provided on the outer wall of the dredging roller 42 will roll while being close to the surface of the dust removal device 6, and the dredging column 421 will be pushed into the adsorption holes of the dust removal device 6, so that the impurities in the holes of the dust removal device 6 are extruded to the other side of the dust removal device 6. At this time, the cleaning assembly 5 can synchronously collect and clean under the drive of the dredging assembly 4. Along with the movement track of the sliding arm 411 driving the dredging roller 42, the dredging roller 42 is under the extrusion force of the dust removal device 6, so that the sliding arm 411 correspondingly retracts into the elastic adaptive member 41. At this time, the sliding arm 411 will squeeze the first spring 412, causing the first spring 412 to store energy. When the sliding arm 411 drives the dredging roller 42 to move to the side of the dust removal device 6, the first spring 412 correspondingly releases the elastic force, causing the sliding arm 411 to drive the dredging roller 42 to extend a corresponding length to clean the holes of the dust removal device 6.

[0045] Through the action of the dredging assembly 4, it can well adapt to the holes used by the dust removal device 6 to adsorb impurities, so that the dredging assembly 4 deeply cleans the adsorption holes of the dust removal device 6, and during the cleaning process of the dredging assembly 4, it will not affect the purification and adsorption functions of other holes.

[0046] As a further solution of the present invention, the cleaning assembly 5 includes: a positioning track 51, a guiding member 52, a limiting column 521, a second spring 522, a material storage scraping plate 53, a sliding handle 531, a positioning column 532, a one-way steering member 54, a shaft 541, and a sliding cleaning member 55. The upper end of the sliding cleaning member 55 is rotatably connected to the end of the linkage handle 422, the lower end of the sliding cleaning member 55 is slidably connected to the groove of the positioning track 51, the bottom of the positioning track 51 is fixedly connected to the inner wall of the smoke inlet pipe 2, one end of the guiding member 52 is fixedly connected to the inner wall of the smoke inlet pipe 2, the other end of the guiding member 52 is fixedly connected to one end of the limiting column 521, the rod body of the limiting column 521 is slidably connected to the hole of the sliding handle 531, the outer wall of the limiting column 521 is sleeved and connected with the second spring 522, the end of the sliding handle 531 is fixedly connected to the side of the material storage scraping plate 53, the side of the material storage scraping plate 53 is fixedly connected to the end of the positioning column 532, the upper part of the material storage scraping plate 53 is fixedly connected to the end of the shaft 541, and the shaft 541 penetrates and rotatably connects to the end face of the one-way steering member 54;

[0047] The sliding cleaning member 55 further includes: a scraping member 551 and a top member 552. The front portion of the sliding cleaning member 55 is fixedly connected to the end of the scraping member 551, and the upper portion of the sliding cleaning member 55 is fixedly connected to the end of the top member 552.

[0048] When the dredging roller 42 moves, the dredging roller 42 will drive the sliding cleaning member 55 to move synchronously through the linkage handle 422. At this time, the sliding cleaning member 55 drives the scraping member 551 to move close to the surface of the dust removal device 6, so that the sliding cleaning member 55 cleans the impurities cleaned by the dredging component 4. Because the impurities in the smoke are sticky, the impurities will accumulate on the inclined surface of the scraping member 551 after being scratched by the scraping member 551. At this time, the sliding cleaning member 55 will slide under the restriction of the positioning track 51. When the sliding cleaning member 55 drives the top member 552 to press against the inclined surface of the one-way steering member 54, the one-way steering member 54 cannot rotate because the side of the one-way steering member 54 is pressed against by the positioning column 532. At this time, the one-way steering member 54 is pressed against by the top member 552, so that the one-way steering member 54 drives the storage scraper 53 to move toward the rear. At this time, the storage scraper 53 moves toward the guide member 52 on the rear side through the sliding handle 531. At this time, the spring 2 522 is also compressed, and the scraper member 551 is The inclined surface will continue to move through the gap created by the movement of the material storage scraper 53 without being blocked by the material storage scraper 53. When the top member 552 moves to the side of the one-way steering member 54, it can no longer resist the one-way steering member 54. At this time, the top member 552 drives the material storage scraper 53 to reset. At this time, the sliding cleaning member 55 will move toward the other side of the dust removal device 6 along with the dredging roller 42. At this time, the opening edge of the material storage scraper 53 will press against the inclined edge of the scraper member 551. At this time, as the scraper member 551 moves, the material storage scraper 53 will scrape off the impurities accumulated on the scraper 551, and as the scraped impurities accumulate, the impurities enter the cavity of the storage scraper 53 for centralized collection, and when the top piece 552 presses against the one-way steering piece 54 from the side of the one-way steering piece 54, the positioning column 532 cannot continue to press against the side of the one-way steering piece 54, and then the one-way steering piece 54 will rotate, so that the top piece 552 moves out, and when the scraper 551 is completely moved out, the storage scraper 53 and the one-way steering piece 54 will be reset.

[0049] By setting the cleaning component 5, the impurities cleaned from the dust removal device 6 are collected centrally, which prevents the impurities cleaned from the dust removal device 6 from diffusing to the inner wall of the absorption tower 1 due to lack of centralized collection, thereby affecting the subsequent desulfurization treatment.
