Description

Technical Field

[0001] The utility model relates to the technical field of dry activated carbon desulfurization and denitration, and particularly relates to a flange short section for the position of activated carbon for desulfurization and denitration. Background Art

[0002] The dry activated carbon desulfurization and denitration technology has been widely applied in large steel plants and power plants. The activated carbon is always in a dynamic state during operation in the device. Wherever the activated carbon passes through, the steel will be punched through by the activated carbon. To solve this problem, a method of setting baffle plates in the device and equipment is adopted, that is, a stacking form is formed, so that the activated carbon walks on the stacked material, and thus other positions of the equipment and device will not be worn. However, when the activated carbon passes through the short section position, due to the original angle of the activated carbon entering the short section and the incomplete certainty of the walking of its own particles, the short section position is extremely easy to be worn, and even if the outer wall is repaired, it is still easy to be worn and cause material leakage.

[0003] The existing solution is to use wear-resistant glue to plug the leakage point at the short section position. However, after a long time, there will still be leakage points near the wear-resistant glue, resulting in wear around the wear-resistant glue, and even the whole wear-resistant glue will fall off and enter the system, affecting the normal production operation. Moreover, the wear is frequent. Repairing the outer wall only treats the symptoms but not the root cause. The inner wall is the normal pipeline inner wall, and it is urgent to solve this problem from the source. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flange short section for the position of activated carbon for desulfurization and denitration. The flange short section for the position of activated carbon for desulfurization and denitration reduces the breakage probability, reduces the maintenance workload, and effectively avoids the leakage of carbon powder and carbon particles caused by wear.

[0005] To achieve the above purpose, the utility model provides a flange short section for the position of activated carbon for desulfurization and denitration. The flange short section for the position of activated carbon for desulfurization and denitration includes a flange short section body. An annular retaining ring is formed on the inner wall of the flange short section body along the circumferential direction. A vertical plate is arranged inside the annular retaining ring and forms a steel trough for holding materials.

[0006] Preferably, the width of the annular retaining ring is 1 / 7 - 1 / 6 of the inner diameter of the flange short section body.

[0007] Preferably, the annular retaining ring extends along the radial direction of the flange short section body.

[0008] Preferably, the annular retaining ring extends upward along the radial direction of the flange short section body and forms an angle of 30 - 45° with the radial direction of the flange short section body.

[0009] Preferably, the annular retaining ring extends downward along the radial direction of the flange nipple body and forms an angle of 30-45° with the radial direction of the flange nipple body.

[0010] Preferably, the annular retaining ring is fixedly connected to the flange nipple body by electric welding.

[0011] Preferably, the annular retaining ring is composed of multiple steel plates connected end to end.

[0012] Preferably, adjacent steel plates are fixed by electric welding.

[0013] According to the above technical solution, the present utility model forms an annular retaining ring along the circumferential direction on the inner wall of the flange nipple body, and a vertical plate is arranged inside the annular retaining ring to form a steel trough for holding materials. In this way, during operation, the steel trough is filled with activated carbon, and the subsequent activated carbon gradually falls onto the activated carbon in the steel trough, and then all pass through the flange nipple. The problem of easy breakage of the flange nipple is solved by the method of material hitting material, thereby avoiding the leakage of carbon powder and carbon particles due to wear.

[0014] Other features and advantages of the present utility model will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] DESCRIPTION OF THE REFERENCE NUMERALS

[0022] 1 - flange nipple body 2 - annular retaining ring

[0023] 3 - vertical plate, 4 - steel channel Specific embodiments

[0024] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present utility model, and are not used to limit the present utility model.

[0025] In the present utility model, unless otherwise stated, the directional terms such as "inner, outer, upper, lower" included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0026] See Figure 1 and Figure 2 The present utility model provides a flange nipple for the position of desulfurization and denitrification activated carbon. The flange nipple for the position of desulfurization and denitrification activated carbon includes a flange nipple body 1. An annular retaining ring 2 is formed along the circumferential direction on the inner wall of the flange nipple body 1. A vertical plate 3 is arranged around the inner side of the annular retaining ring 2 and forms a steel channel 4 for holding materials.

[0027] Through the above technical solution, an annular retaining ring 2 is formed along the circumferential direction on the inner wall of the flange nipple body 1, and a vertical plate 3 is arranged around the inner side of the annular retaining ring 2 to form a steel channel 4 for holding materials. In this way, during operation, the steel channel 4 is filled with activated carbon, and the subsequent activated carbon to be fed gradually falls onto the activated carbon in the steel channel 4, and then all pass through the flange nipple body 1. The problem of easy breakage of the flange nipple is solved by the method of material hitting material, and further, the leakage of carbon powder and carbon particles due to wear is avoided.

[0028] In this embodiment, in order to avoid the situation that the width of the annular retaining ring 2 is too large and affects the amount of the subsequent activated carbon to be fed, or the width is too small and the function of material hitting material is lost due to the inability to hold enough activated carbon, preferably, the width of the annular retaining ring 2 is 1 / 7 - 1 / 6 of the inner diameter of the flange nipple body 1.

[0029] In the first embodiment, as Figure 3 shown, in order to enable the annular retaining ring 2 to hold materials at a moderate speed and fill the steel channel 4, so as to facilitate the realization of material hitting material, preferably, the annular retaining ring 2 extends along the radial direction of the flange nipple body 1.

[0030] In the second embodiment, as Figure 4 shown, in order to enable the annular retaining ring 2 to hold materials at a relatively fast speed and fill the steel channel 4, so as to realize material hitting material as soon as possible according to the usage requirements, preferably, the annular retaining ring 2 extends upward along the radial direction of the flange nipple body 1 and forms an angle of 30 - 45° with the radial direction of the flange nipple body 1.

[0031] In a third embodiment, as Figure 5 As shown, in order to enable the annular retaining ring 2 to scoop up materials at a slower speed and fill the steel groove 4, so as to slowly realize material punching according to usage needs, preferably, the annular retaining ring 2 extends downward along the radial direction of the flange short section body 1 and forms an angle of 30-45° with the radial direction of the flange short section body 1.

[0032] In addition, in order to simplify the operation during installation and fixation and to quickly and conveniently disassemble and replace the annular retaining ring 2 with a new one during maintenance after long-term use, the annular retaining ring 2 is preferably fixed to the flange short section body 1 by electric welding.

[0033] At the same time, in order to reduce the workload of replacing the annular retaining ring 2 during maintenance and avoid the waste of manpower and material costs caused by the need to replace the entire annular retaining ring 2 due to damage at a certain part of the annular retaining ring 2, the annular retaining ring 2 is preferably composed of multiple steel plates connected end to end.

[0034] It is further preferred to fix adjacent steel plates by electric welding. In this way, not only is the installation and disassembly operation convenient, but also a single steel plate can be adjusted upward or downward along the radial direction of the flange short section body 1 according to specific needs during use, which is flexible and has a wider range of applications.

[0035] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0037] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
