Abstract
Description
Technical Field
[0001] This utility model relates to the field of ammonium sulfate production technology, and in particular to an ammonium sulfate drying system. Background Technology
[0002] In related technologies, during the production of ammonium sulfate, the mother liquor passes through a saturator to generate ammonium sulfate crystals. These crystals are then fed into an ammonium sulfate drying and discharge assembly for drying and output. However, the ammonium sulfate drying and discharge assembly frequently requires shutdown for maintenance. During this time, the assembly will be unable to discharge normally, leading to increased resistance in the corresponding saturator and affecting system safety. Shutting down the saturator not only reduces production efficiency but also allows high-ammonia-content coal gas to enter the downstream crude benzene section, causing emulsification of the washing oil and disrupting normal production operations.

The inlet of the transfer inflow pipeline is detachably connected to the outlet of the discharge saturator, and the outlet of the transfer inflow pipeline is detachably connected to the active ammonium sulfate discharge assembly. This ammonium sulfate drying system, by using the transfer inflow pipeline, allows the ammonium sulfate crystals discharged from the saturator of the shut-down module to be discharged into the active ammonium sulfate discharge assembly, thus avoiding the risk of increased resistance in the saturator of the shut-down module and ensuring safety. Furthermore, by setting up a transfer inflow pipeline, it is not necessary to shut down the saturator corresponding to the ammonium sulfate drying discharge component, thus ensuring the production efficiency of the entire ammonium sulfate drying system and guaranteeing normal production operations.

[0040] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0043] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0044] In related technologies, during the production of ammonium sulfate, the mother liquor passes through a saturator to generate ammonium sulfate crystals. These crystals are then fed into an ammonium sulfate drying and discharge assembly for drying and output. However, the ammonium sulfate drying and discharge assembly frequently requires shutdown for maintenance. During this time, the assembly will be unable to discharge normally, leading to increased resistance in the corresponding saturator and affecting system safety. Shutting down the saturator not only reduces production efficiency but also allows high-ammonia-content coal gas to enter the downstream crude benzene section, causing emulsification of the washing oil and disrupting normal production operations.
[0045] To solve the above problems, such as Figure 1and Figure 2 As shown, this embodiment provides an ammonium sulfate drying system, which includes at least two ammonium sulfate drying modules 1. Each ammonium sulfate drying module 1 includes a connected saturator 11 and an ammonium sulfate drying discharge assembly 12. The ammonium sulfate drying system also includes a transfer inflow pipe 2. When the ammonium sulfate drying discharge assembly 12 in one of the ammonium sulfate drying modules 1 stops, the saturator 11 corresponding to the stopped ammonium sulfate drying discharge assembly 12 becomes the saturator to be discharged. The inlet of the transfer inflow pipe 2 is detachably connected to the outlet of the saturator to be discharged, and the outlet of the transfer inflow pipe 2 is detachably connected to the ammonium sulfate drying discharge assembly 12 that is not stopped. The ammonium sulfate drying system provided in this embodiment, by setting the transfer inflow pipe 2, discharges the ammonium sulfate crystals discharged from the saturator 11 corresponding to the stopped ammonium sulfate drying discharge assembly 12 into the ammonium sulfate drying discharge assembly 12 that is not stopped for discharge, avoiding the danger of increased resistance in the saturator 11 corresponding to the stopped ammonium sulfate drying discharge assembly 12, and ensuring safety. Furthermore, by setting up the transfer inflow pipeline 2, it is not necessary to shut down the saturator 11 corresponding to the ammonium sulfate drying discharge component 12, which is shut down, thus ensuring the production efficiency of the entire ammonium sulfate drying system and ensuring normal production operations.
[0046] Furthermore, it should be noted that by setting up the transfer inflow pipe 2, compared to the traditional method of shutting down the saturator 11 corresponding to the stopped ammonium sulfate drying discharge assembly 12, the daily ammonium sulfate production can be increased by approximately 70 tons. It should also be noted that when all the ammonium sulfate drying discharge assemblies 12 in each ammonium sulfate drying module 1 are operating normally, the transfer inflow pipe 2 can be disassembled, eliminating the need to install it at the corresponding location. It should be noted that the transfer inflow pipe 2 can be detachably threadedly connected at the corresponding location via a flange; since the specific connection structure and principle are existing technology, they will not be elaborated upon here.
[0047] Optionally, in this embodiment, the transition inlet pipe 2 is made of stainless steel to ensure the structural strength of the transition inlet pipe 2. Optionally, the pressure rating of the transition inlet pipe 2 is PN16.
[0048] This embodiment uses an ammonium sulfate drying system comprising two ammonium sulfate drying modules 1 as an example for illustrative purposes. In other embodiments, the ammonium sulfate drying system may include three or more ammonium sulfate drying modules 1.
[0049] Optionally, such as Figure 1 As shown, a transfer pump 21 is installed on the transfer inflow pipeline 2. By installing the transfer pump 21 on the transfer inflow pipeline 2, the ammonium sulfate crystals discharged from the saturator 11 corresponding to the shut-down ammonium sulfate drying discharge assembly 12 can be discharged more reliably through the transfer inflow pipeline 2 into the non-shut-down ammonium sulfate drying discharge assembly 12 for discharge.
[0050] Optionally, in this embodiment, each ammonium sulfate drying module 1 may include one saturator 11, or two or more saturators 11 connected in parallel. The specific number of saturators 11 in the ammonium sulfate drying module 1 can be set according to requirements. Optionally, in this embodiment, the saturator 11 can be a spray-type saturator.
[0051] Optionally, such as Figure 1 and Figure 2 As shown, the ammonium sulfate drying and discharging assembly 12 includes a crystallization tank group 121, a centrifuge 122, and a discharge machine 123. The crystallization tank group 121 includes at least two independently arranged crystallization tanks 1211, each connected to a saturator 11. When one of the ammonium sulfate drying modules 1 in the ammonium sulfate drying and discharging assembly 12 stops, the outlet of the transfer inflow pipe 2 is detachably connected to the crystallization tank group 121 in the non-stop ammonium sulfate drying and discharging assembly 12. Each crystallization tank 1211 is connected to a centrifuge 122, and the discharge machine 123 is connected to the centrifuge 122. This structural design of the ammonium sulfate drying and discharging assembly 12 allows the ammonium sulfate crystals discharged from the saturator 11 to first enter the crystallization tank 1211 for further crystallization, then be separated by the centrifuge 122. The ammonium sulfate crystals separated by the centrifuge 122 are then transported by the discharge machine 123 to the subsequent drying bed for drying, thereby forming the desired ammonium sulfate product. By having the ammonium sulfate crystals discharged from the saturator 11 pass sequentially through the crystallization tank 1211 and the centrifuge 122 before being output through the discharge machine 123, the purity of the obtained ammonium sulfate crystals is ensured, and the ammonium sulfate mother liquor is avoided from being mixed in with the ammonium sulfate crystals entering the discharge machine 123. Optionally, the discharge machine 123 can be a auger-type discharge machine.
[0052] Optionally, in this embodiment, the crystallization tank group 121 further includes a first valve group 1212, a crystallization conveying main pipe 1213, and a crystallization conveying branch pipe 1214. When the ammonium sulfate drying discharge component 12 in one of the ammonium sulfate drying modules 1 stops, the outlet of the transfer inflow pipe 2 is detachably connected to the first valve group 1212 in the ammonium sulfate drying discharge component 12 that has not stopped. The inlet of the crystallization conveying main pipe 1213 is connected to the saturator 11, and the outlet of the crystallization conveying main pipe 1213 is connected to the first valve group 1212. The inlet of each crystallization tank 1211 is connected to the crystallization conveying branch pipe 1214, and the inlet of each crystallization conveying branch pipe 1214 is connected to the first valve group 1212. The structural design of the crystallization tank group 121 ensures that ammonium sulfate crystals transported from the transfer inflow pipe 2 and the crystallization transport main pipe 1213 both pass through the first valve group 1212 and then through the crystallization transport branch pipe 1214 into the corresponding crystallization tank 1211. Furthermore, the flow rate of ammonium sulfate crystals entering each crystallization tank 1211 can be rationally distributed by adjusting the connectivity of each valve port in the first valve group 1212. For example, when the crystallization tank group 121 includes two independently configured crystallization tanks 1211, the first valve group 1212 is a four-way valve. When the crystallization tank group 121 includes other numbers of crystallization tanks 1211, the first valve group 1212 can be designed as the required valve group. Since the specific structure of the first valve group 1212 and the on / off adjustment between each valve port are existing technologies, they will not be described in detail here.
[0053] Optionally, in this embodiment, a crystallization pump (not shown in the figure) is provided on the crystallization conveying main pipe 1213 to ensure that the ammonium sulfate crystals generated in the saturator 11 are more reliably and smoothly fed into the required crystallization tank 1211.
[0054] Optionally, in this embodiment, as Figure 2 As shown, the ammonium sulfate drying and discharge assembly 12 also includes a first reflux pipe 124. The inlet of the first reflux pipe 124 is connected to the crystallization tank assembly 121, and the outlet of the first reflux pipe 124 is connected to the saturator 11. By setting the first reflux pipe 124, the residual ammonium sulfate mother liquor in the crystallization tank 1211 can be refluxed back to the saturator 11 for re-crystallization, thus avoiding the waste of ammonium sulfate mother liquor.
[0055] Optionally, such as Figure 2As shown, the ammonium sulfate drying system provided in this embodiment also includes a first transfer return pipeline 3. When the ammonium sulfate drying discharge assembly 12 in one of the ammonium sulfate drying modules 1 stops, the inlet of the first transfer return pipeline 3 is detachably connected to the crystallization tank group 121 in the ammonium sulfate drying discharge assembly 12 that has not stopped, and the outlet of the first transfer return pipeline 3 is connected to the saturator to be discharged. By setting the first transfer return pipeline 3, the residual ammonium sulfate mother liquor in the crystallization tank group 121 in the ammonium sulfate drying discharge assembly 12 that has not stopped can be returned to the saturator to be discharged for re-crystallization through the first transfer return pipeline 3, so as to avoid the saturator 11 corresponding to the ammonium sulfate drying discharge assembly 12 that has not stopped being unable to fully crystallize the returned ammonium sulfate mother liquor.
[0056] Optionally, such as Figure 2 As shown, a first reflux pump 31 is installed on the first transfer reflux pipeline 3. By installing the first reflux pump 31, the residual ammonium sulfate mother liquor in the crystallization tank group 121 of the ammonium sulfate drying and discharge assembly 12 that has not been shut down can be more reliably refluxed to the saturator to be discharged.
[0057] Optionally, in this embodiment, as Figure 2 As shown, the first reflux pipeline 124 includes a second valve group 1241, a first reflux main pipe 1242, and a first reflux main pipe 1242. When the ammonium sulfate drying discharge assembly 12 in one of the ammonium sulfate drying modules 1 stops, the inlet of the first transfer reflux pipeline 3 is detachably connected to the second valve group 1241 in the ammonium sulfate drying discharge assembly 12 that has not stopped. The outlet of the first reflux main pipe 1242 is connected to the saturator 11, and the inlet of the first reflux main pipe 1242 is connected to the second valve group 1241. The reflux port of each crystallization tank 1211 is connected to a first reflux branch pipe 1243, and the outlet of each first reflux branch pipe 1243 is connected to the second valve group 1241. The structural design of the first reflux pipeline 124 ensures that the ammonium sulfate mother liquor refluxed from each crystallization tank 1211 passes through the second valve group 1241. A portion of it is then refluxed through the first reflux main pipe 1242 to the saturator 11 corresponding to the unshutted ammonium sulfate drying discharge assembly 12, while the remaining portion is refluxed through the first transfer reflux pipeline 3 to the saturator to be discharged, thus rationally distributing the flow rate of the ammonium sulfate mother liquor refluxed to each saturator 11. For example, when the crystallization tank group 121 includes two independently configured crystallization tanks 1211, the second valve group 1241 is a four-way valve. When the crystallization tank group 121 includes other numbers of crystallization tanks 1211, the second valve group 1241 can be designed as the required valve group. Since the specific structure of the second valve group 1241 and the on / off adjustment between each valve port are existing technologies, they will not be described in detail here.
[0058] Optionally, in this embodiment, as Figure 2As shown, the ammonium sulfate drying and discharge assembly 12 also includes a second reflux pipeline 125. The inlet of the second reflux pipeline 125 is connected to the centrifuge 122, and the outlet of the second reflux pipeline 125 is connected to the saturator 11. By setting the second reflux pipeline 125, the residual ammonium sulfate mother liquor after separation by the centrifuge 122 can be refluxed back to the saturator 11 for re-crystallization, thus avoiding waste of the ammonium sulfate mother liquor.
[0059] Optionally, such as Figure 2 As shown, the ammonium sulfate drying system also includes a second transfer return pipeline 4. When the ammonium sulfate drying discharge assembly 12 in one of the ammonium sulfate drying modules 1 stops, the inlet of the second transfer return pipeline 4 is detachably connected to the centrifuge 122 in the ammonium sulfate drying discharge assembly 12 that is not stopped, and the outlet of the second transfer return pipeline 4 is connected to the saturator to be discharged. By setting the second transfer return pipeline 4, the ammonium sulfate mother liquor separated by the centrifuge 122 in the ammonium sulfate drying discharge assembly 12 that is not stopped can be returned to the saturator to be discharged for re-crystallization through the second transfer return pipeline 4, thus avoiding the saturator 11 corresponding to the ammonium sulfate drying discharge assembly 12 that is not stopped from being unable to fully crystallize the returned ammonium sulfate mother liquor.
[0060] Optionally, such as Figure 2 As shown, a second reflux pump 41 is installed on the second transfer reflux pipeline 4. By installing the second reflux pump 41, the ammonium sulfate mother liquor separated from the centrifuge 122 in the ammonium sulfate drying and discharging assembly 12, which is not shut down, can be more reliably refluxed back to the saturator to be discharged.
[0061] Optionally, such as Figure 2As shown, the second reflux pipeline 125 includes a third valve group 1251, a second reflux main pipe 1252, and a second reflux branch pipe 1253. When the ammonium sulfate drying discharge assembly 12 in one of the ammonium sulfate drying modules 1 stops, the inlet of the second transfer reflux pipeline 4 is detachably connected to the third valve group 1251 in the ammonium sulfate drying discharge assembly 12 that has not stopped. The outlet of the second reflux main pipe 1252 is connected to the saturator 11, and the inlet of the second reflux main pipe 1252 is connected to the third valve group 1251. The reflux port of each centrifuge 122 is connected to the second reflux branch pipe 1253, and the outlet of each second reflux branch pipe 1253 is connected to the third valve group 1251. The structural design of the second return pipeline 125 ensures that the ammonium sulfate mother liquor returned from each centrifuge 122 passes through the third valve group 1251. A portion of this liquor then flows back through the second return main pipeline 1252 to the saturator 11 corresponding to the unstopped ammonium sulfate drying discharge assembly 12, while the remaining portion flows back through the second transfer return pipeline 4 to the saturator to be discharged. This rationally distributes the flow rate of the ammonium sulfate mother liquor returning to each saturator 11. For example, the ammonium sulfate drying discharge assembly 12 includes two centrifuges 122, in which case the third valve group 1251 is a four-way valve. When the ammonium sulfate drying discharge assembly 12 includes other numbers of centrifuges 122, the third valve group 1251 can be designed as the required valve group. Since the specific structure of the third valve group 1251 and the on / off adjustment between each valve port are existing technologies, they will not be described in detail here.
[0062] Optionally, in this embodiment, the first reflux manifold 1242 is connected to the second reflux manifold 1252, so that the first reflux manifold 1242 and the second reflux manifold 1252 can be combined and refluxed together into the saturator 11. Optionally, in other embodiments, a suction pump is provided on the first reflux manifold 1242 or the second reflux manifold 1252, thereby ensuring that the ammonium sulfate mother liquor refluxed from the first reflux manifold 1242 and the second reflux manifold 1252 is more reliably fed into the saturator 11.
[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
