Description

Technical Field

[0001] This utility model relates to the field of acid separator technology, and in particular to an alloy cast iron tube-type acid separator. Background Technology

[0002] An acid separator is an internal component of a tower that distributes acid evenly across the surface of the packing material. It is suitable for use in drying and absorption towers in sulfuric acid plants. Acid separators are mainly classified into two types: trough-type and tubular-type. A typical tubular-type acid separator consists of a main inlet pipe, a main distribution pipe, branch pipes, and spray nozzles. During operation, concentrated sulfuric acid first enters the separator through the main inlet pipe, is then distributed to the branch pipes by the main distribution pipe, and finally sprayed out through the spray nozzles on the branch pipes, thus spraying the concentrated sulfuric acid onto the packing layer below.

[0003] However, existing tubular acid separators cannot rotate multiple spray holes during use. Due to the certain distance between each spray hole, it is difficult to achieve uniform coverage of the acid solution on the surface of the packing layer when spraying concentrated sulfuric acid onto the packing layer below, thus affecting the overall spray uniformity.

[0004] Therefore, it is necessary to provide an alloy cast iron tubular acid separator to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem that existing tubular acid distributors, due to the spacing between spray holes, make it difficult to achieve uniform acid coverage on the packing layer surface, thus affecting the overall spray uniformity, this utility model provides an alloy cast iron tubular acid distributor.

[0006] The alloy cast iron tubular acid separator provided by this utility model includes: a housing, on which an acid inlet main pipe is fixedly installed, and a through pipe is rotatably installed on the acid inlet main pipe, the through pipe being rotatably connected to the bottom of the housing; an acid separator main pipe fixedly installed on the through pipe, the acid separator main pipe being made of alloy cast iron, and multiple mounting pipes fixedly installed on the acid separator main pipe, each of the multiple mounting pipes having a branch pipe fixedly installed, and each of the multiple branch pipes having multiple spray holes; and a rotating mechanism assembled on the housing for rotating the through pipe.

[0007] Preferably, the rotating mechanism includes: a servo motor fixedly installed on the inner wall of the bottom of the housing, with a first bevel gear fixedly sleeved on the output shaft of the servo motor; and a second bevel gear fixedly sleeved on the through pipe, the second bevel gear meshing with the first bevel gear.

[0008] Preferably, an annular plate is fixedly installed at the bottom of the box body, and an annular groove is formed on the annular plate. Two sliders are slidably installed on the inner wall of the annular groove, and a bracket is fixedly installed on each of the two sliders. One end of each of the two brackets is fixedly connected to the outer wall of the acid distribution manifold.

[0009] Preferably, the inner walls of the plurality of spray holes are threaded with bushings for protecting the spray holes, and the bushings are made of polytetrafluoroethylene.

[0010] Preferably, each of the multiple branch pipes has a first inspection port at one end, and each of the multiple first inspection ports has a first sealing cap.

[0011] Preferably, a second inspection port is provided at both ends of the acid distribution main pipe, and a second sealing cap is provided on each of the two second inspection ports.

[0012] Preferably, multiple T-shaped brackets are fixedly installed on the top of the housing, and each of the multiple T-shaped brackets has multiple mounting holes for installing screws.

[0013] Compared with related technologies, the alloy cast iron tubular acid separator provided by this utility model has the following beneficial effects:

[0014] This invention provides an alloy cast iron tubular acid distributor. Through the main acid inlet pipe, concentrated sulfuric acid is delivered to the connecting pipe. The connecting pipe then delivers the concentrated sulfuric acid to multiple branch pipes via the main acid distributor pipe and multiple mounting pipes, finally spraying it out from multiple spray holes. A rotating mechanism drives the connecting pipe to rotate on the housing and the main acid inlet pipe. The connecting pipe, in turn, drives the main acid distributor pipe to rotate, which in turn drives the multiple branch pipes to rotate. This causes the multiple spray holes on the branch pipes to rotate, expanding the coverage area of ​​the acid sprayed from the multiple spray holes during rotation. This achieves uniform spraying of the lower packing layer, effectively solving the technical problem in existing tubular acid distributors where the spacing between the spray holes makes it difficult to achieve uniform acid coverage on the packing layer surface, thus affecting the overall spray uniformity.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides an alloy cast iron tubular acid separator, such as... Figure 1-4 As shown, the alloy cast iron tubular acid separator includes: a housing 1, on which an acid inlet main pipe 2 is fixedly installed, and a through pipe 3 is rotatably installed on the acid inlet main pipe 2, the through pipe 3 being rotatably connected to the bottom of the housing 1; an acid separator main pipe 4 fixedly installed on the through pipe 3, the acid separator main pipe 4 being made of alloy cast iron, and multiple mounting pipes 5 fixedly installed on the acid separator main pipe 4, each of the multiple mounting pipes 5 having a branch pipe 6 fixedly installed, each of the multiple branch pipes 6 having multiple spray holes 7; and a rotating mechanism assembled on the housing 1 for rotating the through pipe 3.

[0023] In this embodiment, the main acid inlet pipe 2, the through pipe 3, the main acid distribution pipe 4, the installation pipe 5, and the branch pipes 6 are all made of alloy cast iron, which can effectively ensure the structural strength and corrosion resistance of the acid distributor. When the acid distributor is working, concentrated sulfuric acid is transported into the main acid inlet pipe 2 through the corresponding pipes, and then flows into the through pipe 3. The through pipe 3 will transport the concentrated sulfuric acid into the main acid distribution pipe 4, and the main acid distribution pipe 4 will distribute the concentrated sulfuric acid into multiple branch pipes 6, and finally spray it out from multiple spray holes 7. During this process, a rotating mechanism is also required. The rotating mechanism will drive the through pipe 3 to rotate on the housing 1 and the main acid inlet pipe 2. The through pipe 3 will drive the main acid distribution pipe 4 to rotate. The main acid distribution pipe 4 will drive the multiple branch pipes 6 to rotate through multiple installation pipes 5, so that the multiple spray holes 7 on the multiple branch pipes 6 will rotate. This allows the acid sprayed from the multiple spray holes 7 to expand the coverage area during the rotation, thereby achieving uniform spraying of the lower packing layer and greatly improving the spray uniformity.

[0024] In a further preferred embodiment of the present invention, the rotating mechanism includes: a servo motor 8 fixedly installed on the inner wall of the bottom of the housing 1, a first bevel gear 9 fixedly sleeved on the output shaft of the servo motor 8; and a second bevel gear 10 fixedly sleeved on the through pipe 3, the second bevel gear 10 meshing with the first bevel gear 9.

[0025] In this embodiment, the rotating mechanism is used to rotate the through pipe 3. When in use, the servo motor 8 is started, and the servo motor 8 drives the first bevel gear 9 to rotate. The first bevel gear 9 drives the through pipe 3 to rotate on the housing 1 and the acid inlet main pipe 2 through the second bevel gear 10. The through pipe 3 drives the acid distribution main pipe 4 to rotate. The acid distribution main pipe 4 drives the multiple branch pipes 6 to rotate through multiple installation pipes 5. In this way, the acid sprayed from the multiple spray holes 7 can expand the coverage area during the rotation process, which greatly improves the spray uniformity.

[0026] In a further preferred embodiment of the present invention, an annular plate 11 is fixedly installed at the bottom of the box 1. An annular groove is provided on the annular plate 11. Two sliders 12 are slidably installed on the inner wall of the annular groove. A bracket 13 is fixedly installed on each of the two sliders 12. One end of each of the two brackets 13 is fixedly connected to the outer wall of the acid distribution main pipe 4.

[0027] In this embodiment, the combined use of the annular plate 11, the annular groove, the two sliders 12 and the two supports 13 can share the supporting force of the through pipe 3 on the acid distribution main pipe 4. When the through pipe 3 drives the acid distribution main pipe 4 to rotate, the two supports 13 fixed to the acid distribution main pipe 4 will simultaneously drive the two sliders 12 to slide in the annular groove.

[0028] In a further preferred embodiment of the present invention, the inner walls of the plurality of spray holes 7 are threadedly fitted with bushings 14 for protecting the spray holes 7, and the bushings 14 are made of polytetrafluoroethylene.

[0029] In this embodiment, when concentrated sulfuric acid is sprayed out from the spray hole 7 through the branch pipe 6, the bushing 14 is in direct contact with the concentrated sulfuric acid. Its polytetrafluoroethylene material has excellent resistance to concentrated sulfuric acid corrosion, which can effectively protect the inner wall of the spray hole 7 made of alloy cast iron from acid corrosion and avoid problems such as increased hole diameter and deformation of the spray hole 7 due to corrosion.

[0030] In a further preferred embodiment of the present invention, a first inspection port is provided at one end of each of the plurality of branch pipes 6, and a first sealing cap 15 is provided on each of the plurality of first inspection ports.

[0031] In this embodiment, by opening the first sealing cover 15, it is convenient for people to perform maintenance and inspection work on the inside of the branch pipe 6 through the first inspection port.

[0032] In a further preferred embodiment of the present invention, a second inspection port is provided at both ends of the acid distribution main pipe 4, and a second sealing cap 16 is provided on each of the two second inspection ports.

[0033] In this embodiment, by opening the second sealing cover 16, it is convenient for people to perform maintenance and inspection work on the inside of the acid distribution main pipe 4 through the second inspection port.

[0034] In a further preferred embodiment of the present invention, a plurality of T-shaped brackets are fixedly installed on the top of the housing 1, and a plurality of mounting holes for mounting screws are provided on the plurality of T-shaped brackets.

[0035] In this embodiment, the acid separator can be easily installed on the corresponding position above the packing layer using screws through the multiple mounting holes on the multiple T-shaped frames.

[0036] In summary, compared with related technologies, this solution, through the main acid inlet pipe 2, can transport the required concentrated sulfuric acid to the connecting pipe 3. The connecting pipe 3 then transports the concentrated sulfuric acid to multiple branch pipes 6 through the main acid distribution pipe 4 and multiple installation pipes 5, and finally sprays it out from multiple spray holes 7. Through the use of the rotating mechanism, the connecting pipe 3 can be driven to rotate on the housing 1 and the main acid inlet pipe 2. The connecting pipe 3 drives the main acid distribution pipe 4 to rotate, and the main acid distribution pipe 4 drives the multiple branch pipes 6 to rotate through the multiple installation pipes 5. This causes the multiple spray holes 7 on the multiple branch pipes 6 to rotate, so that the acid sprayed from the multiple spray holes 7 can expand the coverage area during the rotation, thereby achieving uniform spraying of the packing layer below. This effectively solves the technical problem that in the use of existing tubular acid distributors, due to the certain distance between the spray holes, it is difficult to achieve uniform coverage of the acid on the surface of the packing layer, thus affecting the overall spray uniformity.

[0037] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
