Description

Technical Field

[0001] This utility model relates to the field of denitrification soot blowing technology, and more specifically, it relates to a soot blowing device for a denitrification reactor. Background Technology

[0002] During the operation of the denitrification reactor, dust and other impurities gradually accumulate on the surface of the catalyst. These impurities significantly reduce the activity of the catalyst, thereby affecting the efficiency and effectiveness of the denitrification reaction. Therefore, it is essential to clean the catalyst regularly.

[0003] Currently, existing soot blowing devices for denitrification reactors generally suffer from a key technical deficiency when cleaning the catalyst: the distance between the nozzle and the catalyst is not easily adjustable. In actual operation, dust accumulation on the catalyst surface varies due to various factors, such as different operating times and different flue gas compositions, leading to differences in dust contamination levels at different locations or stages of catalyst operation.

[0004] However, in existing soot blowing devices, the distance between the nozzle and the catalyst is often fixed, making it difficult to adjust in real time and precisely according to the actual dust contamination level. When facing areas with low dust contamination, a fixed nozzle distance may result in energy waste due to being too close, and may also cause unnecessary wear on the catalyst surface due to excessive airflow impact. Conversely, when facing areas with high dust contamination, a fixed nozzle distance may result in insufficient impact force of the airflow reaching the catalyst surface due to being too far, failing to effectively remove stubborn dust and thus affecting the catalyst cleaning effect, ultimately reducing the overall operating performance and service life of the denitrification reactor.

[0005] Therefore, developing a soot blowing device for denitrification reactors that allows for easy adjustment of the distance between the nozzle and the catalyst to effectively clean the catalyst is of significant practical importance. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a soot blowing device for a denitrification reactor that can adjust the distance between the nozzle and the catalyst.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This utility model is further configured as follows: it includes a housing and a first catalyst and a second catalyst disposed inside the housing for purifying dust. The dust blowing device also includes a dust blowing adjustment mechanism and a guiding mechanism. The dust blowing adjustment mechanism is disposed on the top of the housing and includes a sliding part, a first jet pipe, and a nozzle. The sliding part is slidably disposed on the top of the housing. The first jet pipe has multiple parts and is disposed at the bottom of the sliding part, and the top of the housing has multiple guide holes that are clearance-fitted with the first jet pipes. The nozzle has multiple parts and is disposed at the bottom of the first jet pipes. When the sliding part moves, it can drive the multiple first jet pipes and nozzles to move synchronously and gradually approach the top of the first catalyst. The guiding mechanism is disposed inside the housing and is used to guide the dust blown into the housing.

[0009] By adopting the above technical solution, the problem of poor cleaning effect of the first catalyst due to different dust contamination levels is solved, and the technical effect of effectively cleaning the first catalyst with different dust contamination levels is achieved.

[0010] The present invention is further configured such that: the soot blowing adjustment mechanism also includes a first telescopic cylinder and an ejector part; the first telescopic cylinder is disposed on the top of the housing; the ejector part is disposed at the output end of the first telescopic cylinder, and the ejector part is fixedly connected to the sliding part, so that when the first telescopic cylinder is started, it can drive the ejector part and the sliding part to move.

[0011] The present invention is further configured such that: the soot blowing adjustment mechanism also includes a sealing plate, a first air pump and an air delivery pipe; the sealing plate is disposed on the top of the sliding part, and a flow chamber for air to pass through is formed between the sealing plate and the sliding part, the flow chamber being used to deliver air to the first jet pipe and the nozzle; the first air pump has a pair and is disposed on the top of the sealing plate respectively; the air delivery pipe has a pair and is disposed on the side of the first air pump respectively, and the air delivery pipe is connected to the sealing plate.

[0012] The present invention is further configured such that: the guiding mechanism includes a first guide plate; the first guide plate is disposed inside the housing, and the first guide plate is provided with multiple ash guiding grooves, and the multiple ash guiding grooves are all rectangular parallelepipeds, and the multiple rectangular parallelepiped ash guiding grooves are arranged at progressively inclined intervals.

[0013] The present invention is further configured such that: the guiding mechanism also includes a guide cover; the guide cover is disposed on the top of the second guide plate, and the top edge of the guide cover is a chamfered structure that fits the inner wall of the housing; the guide cover is used to guide the dust passing through the first guide plate to the top of the second guide plate.

[0014] The present invention is further configured such that: the guiding mechanism also includes a second guiding plate; the second guiding plate is disposed above the first catalyst, and the second guiding plate has multiple guiding grooves, which are spaced apart and gradually inclined.

[0015] The present invention is further configured such that: a second air pump is provided on the side of the housing; and the output end of the second air pump is provided with a plurality of second jet pipes extending into the housing and located above the second catalyst.

[0016] By adopting the above technical solution, in order to effectively clean the second catalyst, the second air pump is started and air is passed through the second jet pipe to clean the area above the second catalyst, thereby ensuring the cleaning effect of the first catalyst and the second catalyst.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] (1) By setting up a soot blowing adjustment mechanism, when it is necessary to adjust the position of the first jet pipe and nozzle to specifically clean the dust attached to the top of the first catalyst, the sliding part first slides along the top of the casing. During this process, the sliding part can drive multiple first jet pipes and nozzles to move closer to the first catalyst, thereby shortening the distance between the nozzle and the first catalyst. The air can more effectively act on the stubborn dust attached to the first catalyst, achieving powerful cleaning. This solves the problem of poor cleaning effect of the first catalyst due to different dust contamination levels, and realizes the technical effect of effectively cleaning the first catalyst with different dust contamination levels.

[0019] (2) By setting up a guiding mechanism, the turbulence generated by dust during the air cleaning process is effectively reduced, avoiding the problem that the air jet force is greatly blocked when flowing through the first catalyst, thus weakening the auxiliary cleaning effect on the second catalyst below. This ensures that the auxiliary cleaning effect on the second catalyst can be effectively exerted. Attached Figure Description

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] Please see Figure 1-7 The present invention provides the following technical solution:

[0031] Example 1 includes a housing 1 and a first catalyst 2 and a second catalyst 3 disposed inside the housing 1 for purifying dust. The dust blowing device also includes a dust blowing adjustment mechanism 4 and a guide mechanism 5. The dust blowing adjustment mechanism 4 is disposed on the top of the housing 1 and includes a sliding part 41, a first jet pipe 42, and nozzles 43. The sliding part 41 is slidably disposed on the top of the housing 1. The first jet pipe 42 has multiple parts and is disposed at the bottom of the sliding part 41, and the top of the housing 1 has multiple guide holes that are clearance-fitted with the first jet pipe 42. The nozzles 43 have multiple parts and are disposed at the bottom of the first jet pipe 42. When the sliding part 41 moves, it can drive the multiple first jet pipes 42 and nozzles 43 to move synchronously and gradually approach the top of the first catalyst 2. The guide mechanism 5 is disposed inside the housing 1 and is used to guide the dust blown into the housing 1.

[0032] Specifically, a dust inlet is provided on the side of the housing 1, and the dust inlet is located next to the sliding part 41. The dust inlet is existing technology and will not be described in detail here. The first jet pipe 42 and the nozzle 43 are both made of high-temperature resistant material, which will not affect the normal use of the first jet pipe 42 and the nozzle 43. Moreover, the sliding part 41 is located on the outside, and the high temperature generated inside the housing 1 during operation will not reduce the performance of the sliding part 41. When it is necessary to adjust the position of the first jet pipe 42 and the nozzle 43 to specifically clean the dust attached to the top of the first catalyst 2, the sliding part 41 first slides along the top of the housing 1. During this process, the sliding part 41 can drive multiple first jet pipes 42 and nozzles 43 to move closer to the first catalyst 2, thereby shortening the distance between the nozzles 43 and the first catalyst 2. The air can more effectively act on the stubborn dust attached to the first catalyst 2, achieving powerful cleaning. This solves the problem of poor cleaning effect of the first catalyst 2 due to different dust contamination levels, and achieves the technical effect of effectively cleaning the first catalyst 2 with different dust contamination levels.

[0033] See Figures 2-5 The soot blowing adjustment mechanism 4 also includes a first telescopic cylinder 44 and an ejector part 45; the first telescopic cylinder 44 is located on the top of the housing 1; the ejector part 45 is located at the output end of the first telescopic cylinder 44 and is fixedly connected to the sliding part 41. When the first telescopic cylinder 44 is started, it can drive the ejector part 45 and the sliding part 41 to move.

[0034] Specifically, when it is necessary to adjust the position of the sliding part 41, the first telescopic cylinder 44 is activated and drives the ejector part 45 to rise. Since the ejector part 45 is connected to the sliding part 41 by fasteners, the ejector part 45 can drive the sliding part 41 to move synchronously when it moves, thereby realizing the adjustment of the distance between the first jet pipe 42 and the nozzle 43 and the first catalyst 2.

[0035] See Figures 3-5 The soot blowing adjustment mechanism 4 also includes a sealing plate 46, a first air pump 47, and an air supply pipe 48; the sealing plate 46 is disposed on the top of the sliding part 41, and a flow chamber for air to pass through is formed between the sealing plate 46 and the sliding part 41, the flow chamber being used to deliver air to the first jet pipe 42 and the nozzle 43; there is a pair of first air pumps 47, which are respectively disposed on the top of the sealing plate 46; there is a pair of air supply pipes 48, which are respectively disposed on the side of the first air pumps 47, and the air supply pipes 48 are connected to the sealing plate 46.

[0036] Specifically, a flow chamber for air passage is formed between the sealing plate 46 and the sliding part 41. When the first air pump 47 is started, it can deliver external air to the space between the sealing plate 46 and the sliding part 41 through the air supply pipe 48. Then, the air is discharged from the flow chamber through the first jet pipe 42 and the nozzle 43, thereby realizing air circulation and ensuring the sealing effect.

[0037] See Figure 6 and Figure 7 The guiding mechanism 5 includes a first guide plate 51; the first guide plate 51 is disposed inside the housing 1, and multiple ash guide grooves are provided on the first guide plate 51, and the multiple ash guide grooves are all rectangular parallelepipeds, and the multiple rectangular parallelepiped ash guide grooves are gradually inclined and spaced apart.

[0038] Specifically, when dust enters the interior of the housing 1 and passes through the position of the first guide plate 51, the first guide plate 51 can divide the dust and air into multiple channels through the dust guide groove. The separated dust will flow in a gradually converging state, making the flow direction of the dust more uniform and concentrated after passing through the first guide plate 51.

[0039] See Figure 6 and Figure 7 The guiding mechanism 5 also includes a guide cover 52; the guide cover 52 is disposed on the top of the second guide plate 53, and the top edge of the guide cover 52 is a chamfered structure that fits the inner wall of the housing 1. The guide cover 52 is used to guide the dust passing through the first guide plate 51 to the top of the second guide plate 53.

[0040] Specifically, when dust flows through the first guide plate 51 to the top of the first catalyst 2, the dust can be guided by the top edge of the guide cover 52 and move downwards towards the first catalyst 2. This reduces the amount of dust floating up when passing through the first guide plate 51 and being above the first catalyst 2, allowing the dust to flow quickly to the top of the first catalyst 2.

[0041] See Figure 6 The guiding mechanism 5 also includes a second guide plate 53; the second guide plate 53 is disposed above the first catalyst 2, and multiple guide grooves are provided on the second guide plate 53, which are spaced apart and gradually inclined.

[0042] Specifically, when dust flows to the area above the first catalyst 2, the first air pump 47 is activated, spraying the dust through the nozzle 43. During this process, the air jet force generated by the nozzle 43 acts on the dust, causing it to move towards the second guide plate 53. The guide grooves on the second guide plate 53 divide the airflow ejected from the nozzle 43, forming an airflow path that gradually diffuses outwards along the direction of the guide grooves. This effectively reduces turbulence caused by dust during air cleaning and avoids weakening the auxiliary cleaning effect on the second catalyst 3 below due to significant obstruction of the air jet force as it flows past the first catalyst 2. This ensures that the auxiliary cleaning effect on the second catalyst 3 is effectively utilized.

[0043] See Figure 1 A second air pump 6 is provided on the side of the housing 1; the output end of the second air pump 6 is provided with a plurality of second jet pipes 7 extending into the housing 1 and located above the second catalyst 3.

[0044] Specifically, in order to effectively clean the second catalyst 3, the second air pump 6 is activated and air is passed through the second jet pipe 7 to clean the area above the second catalyst 3, thereby ensuring the cleaning effect of the first catalyst 2 and the second catalyst 3.

[0045] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
