Description

Technical Field

[0001] This utility model relates to the technical field of ammonia stripping tower dividers, specifically a pressure-resistant ammonia stripping tower divider. Background Technology

[0002] The ammonia stripping tower's water vapor separator is a key piece of equipment in the ammonia stripping system. Located at the top of the stripping tower, it primarily separates and concentrates water vapor from ammonia gas, increasing the ammonia concentration while simultaneously achieving heat recovery and process optimization. Ammonia gas containing water vapor enters the separator from the top of the stripping tower, where it exchanges heat with the cooling water flowing within. The water vapor in the ammonia gas is condensed into liquid and returned to the stripping tower; the uncondensed ammonia gas is concentrated.

[0003] Existing ammonia stripping tower dividers directly deliver cold water into the divider for heat exchange. However, the divider only has a single outer shell, resulting in low pressure resistance during operation. As it needs to handle the high-temperature ammonia vapor mixture escaping from the top of the ammonia stripping tower during operation, the flow of these gases within the divider exerts continuous pressure on the walls. If the divider's pressure resistance is insufficient, prolonged exposure to gas pressure may cause the walls to deform or even rupture, leading to safety accidents. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that the existing cleaning equipment in the above-mentioned technology directly delivers cold water to the interior of the ammonia stripping tower to achieve heat exchange, and the ammonia stripping tower has only a single outer shell, its pressure resistance is low during use, and long-term exposure to gas pressure may lead to deformation or even rupture of the vessel wall, causing safety accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pressure-resistant ammonia stripping tower divider includes a divider shell assembly; a cooling assembly for condensing ammonia gas containing water vapor; and a support assembly for supporting the cooling assembly.

[0008] The shrinkage unit housing assembly includes: a shrinkage unit housing; and an exhaust pipe disposed on the top of the shrinkage unit housing and communicating therewith;

[0009] The cooling assembly includes: a cooling cavity fixed inside the housing of the reducer; and a pressure-resistant reinforcing rib welded to the surface of the cooling cavity.

[0010] The support assembly includes: a support column disposed inside the cooling cavity; a damping outer cylinder fixedly installed around the support column; and a piston rod passing through the inside of the damping outer cylinder.

[0011] As a further embodiment of this utility model: the damping outer cylinder is filled with hydraulic oil, the piston rod is fixedly connected to the inner wall of the cooling cavity, and the damping outer cylinder is evenly distributed at equal intervals along the surface of the supporting column.

[0012] As a further embodiment of this utility model, the cooling assembly further includes: a coolant inlet pipe fixed to the upper side of one side of the cooling cavity; and a coolant outlet pipe fixed to the lower side of one side of the cooling cavity.

[0013] As a further embodiment of this utility model: the coolant inlet pipe and the coolant outlet pipe penetrate the interior of the distributor housing, and the cross-section of the cooling cavity is a circular structure.

[0014] As a further embodiment of this utility model, the shrinkage unit housing assembly further includes a bottom connecting flange welded to the bottom end face of the shrinkage unit housing, and the shrinkage unit housing is installed on the top of the ammonia stripping tower through the bottom connecting flange.

[0015] As a further embodiment of this utility model, the splitter housing assembly further includes a discharge valve installed in the middle of the exhaust pipe, the discharge valve being fixedly connected to the exhaust pipe via a flange.

[0016] As a further embodiment of this utility model: an ammonia condensation assembly is installed inside the housing of the shrinkage unit, the ammonia condensation assembly comprising: two sets of support cover plates disposed inside the housing of the shrinkage unit; and a spiral tube fixed between the support cover plates.

[0017] As a further improvement of this utility model, the spiral tubes are distributed circumferentially along the axis of the reducer housing.

[0018] As a further improvement of this utility model: the cooling cavity is located between two sets of support cover plates, and a high-temperature resistant sealing ring is provided between the support cover plates and the shrinkage unit housing.

[0019] As a further improvement of this utility model, a connection hole corresponding to the spiral tube is provided at the connection between the support cover plate and the spiral tube.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. With the support components provided, the piston rod can move inside the damping outer cylinder and move by pushing the hydraulic oil to provide elastic support to the inner wall of the cooling chamber. In conjunction with the compressive reinforcing ribs of the outer wall, the cooling chamber has a certain compressive strength when subjected to gas pressure. Furthermore, the cooling chamber exists independently inside the shrinkage unit housing and will not affect the shrinkage unit housing.

[0022] 2. This utility model, through the cooling chamber, combined with the upper and lower coolant inlet pipes and coolant outlet pipes, enables the coolant to flow from top to bottom, thereby coming into contact with ammonia gas containing water vapor and condensing the ammonia gas. The uncondensed gas can be discharged to the outside through the outlet valve.

[0023] 3. The present invention uses an ammonia condensation assembly with multiple spiral tubes arranged in a spiral coil between two sets of support cover plates, which increases the residence time of ammonia in the spiral tubes and allows the ammonia to fully contact the coolant in the cooling chamber.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0033] Example 1:

[0034] Please see Figures 1-4 This is the first embodiment of the present invention.

[0035] This embodiment provides a pressure-resistant ammonia stripping tower condenser, including a condenser shell assembly 1; a cooling assembly 2 for condensing ammonia containing water vapor; and a support assembly 4 for supporting the cooling assembly 2.

[0036] The reducer housing assembly 1 includes: a reducer housing 101; and an exhaust pipe 102 disposed on the top of the reducer housing 101 and communicating therewith;

[0037] Cooling assembly 2 includes: a cooling cavity 203 fixed inside the reducer housing 101; and a compressive reinforcing rib 204 welded to the surface of the cooling cavity 203.

[0038] The support assembly 4 includes: a support column 403 disposed inside the cooling cavity 203; a damping outer cylinder 401 fixedly installed around the support column 403; and a piston rod 402 passing through the damping outer cylinder 401.

[0039] Specifically, the damping outer cylinder 401 is filled with hydraulic oil, the piston rod 402 is fixedly connected to the inner wall of the cooling chamber 203, and the damping outer cylinder 401 is evenly distributed at equal intervals along the surface of the support column 403.

[0040] Furthermore, the piston rod 402 can move inside the damping outer cylinder 401 and, by pushing the hydraulic oil, provides elastic support to the inner wall of the cooling chamber 203. When the cooling chamber 203 is subjected to gas pressure, the cooling chamber 203 has a certain pressure resistance.

[0041] In use, the ammonia gas containing water vapor entering the fractionator housing 101 condenses upon contact with the cooling water in the cooling chamber 203. The condensed liquid flows back to the ammonia stripping tower through the fractionator housing 101, while the uncondensed ammonia gas is concentrated and discharged through the exhaust pipe 102 at the top. When the ammonia gas containing water vapor enters the cooling chamber 203, the strength of the outer wall of the cooling chamber 203 is increased due to the pressure-resistant reinforcing ribs 204 around the cooling chamber 203. The piston rod 402 can move inside the damping outer cylinder 401 and, by pushing the hydraulic oil, provides elastic support to the inner wall of the cooling chamber 203. In conjunction with the pressure-resistant reinforcing ribs 204 on the outer wall, the cooling chamber 203 has a certain pressure resistance when subjected to gas pressure. Furthermore, the cooling chamber 203 exists independently inside the fractionator housing 101 and will not affect the fractionator housing 101.

[0042] In summary, through the provided support component 4, the piston rod 402 can move inside the damping outer cylinder 401 and, by pushing the hydraulic oil, provides elastic support to the inner wall of the cooling chamber 203. In conjunction with the compressive strength ribs 204 on the outer wall, the cooling chamber 203 has a certain compressive strength when subjected to gas pressure. Furthermore, the cooling chamber 203 exists independently inside the distributor housing 101 and will not affect the distributor housing 101.

[0043] Example 2:

[0044] Please see Figures 2-4 This is the second embodiment of the present utility model.

[0045] Specifically, the cooling assembly 2 also includes: a coolant inlet pipe 201 fixed to the upper side of one side of the cooling chamber 203; and a coolant outlet pipe 202 fixed to the lower side of one side of the cooling chamber 203.

[0046] Furthermore, the coolant enters the cooling chamber 203 through the coolant inlet pipe 201, and after absorbing heat, it is discharged outward through the coolant outlet pipe 202 on one side of the cooling chamber 203.

[0047] Specifically, the coolant inlet pipe 201 and the coolant outlet pipe 202 pass through the interior of the distributor housing 101, and the cross-section of the cooling chamber 203 is a circular structure.

[0048] Furthermore, the cooling chamber 203 is interconnected with the coolant inlet pipe 201 and the coolant outlet pipe 202, allowing the coolant flowing from top to bottom to come into contact with ammonia gas containing water vapor, thereby condensing the ammonia gas.

[0049] Specifically, the shrinkage unit housing assembly 1 also includes a bottom connecting flange 104 welded to the bottom end face of the shrinkage unit housing 101, and the shrinkage unit housing 101 is installed on the top of the ammonia stripping tower through the bottom connecting flange 104.

[0050] Furthermore, the separator housing 101 is installed on the top of the ammonia stripping tower via the bottom connecting flange 104 and its bolts. The ammonia gas containing water vapor in the top of the ammonia stripping tower can rise into the interior of the separator housing 101 and be condensed by the cooling assembly 2 inside the separator housing 101.

[0051] Specifically, the compressor housing assembly 1 also includes a discharge valve 103 installed in the middle of the exhaust pipe 102, and the discharge valve 103 is fixedly connected to the exhaust pipe 102 via a flange.

[0052] Furthermore, the discharge valve 103 is used to discharge uncondensed gas. The discharge valve 103 can be a solenoid valve and operates under the control of the controller.

[0053] In use, the ammonia separator housing 101 is installed on the top of the ammonia stripping tower via the bottom connecting flange 104 and its bolts. The ammonia gas containing water vapor in the top of the ammonia stripping tower can rise into the interior of the ammonia separator housing 101, where it is condensed by the cooling components 2 inside the housing. The coolant enters the cooling chamber 203 through the coolant inlet pipe 201, and after absorbing heat, it can be discharged outward through the coolant outlet pipe 202 on one side of the cooling chamber 203. The coolant flowing from top to bottom can come into contact with the ammonia gas containing water vapor, thereby condensing the ammonia gas. The uncondensed gas can be discharged outward through the outlet valve 103.

[0054] In summary, the cooling chamber 203, together with the coolant inlet pipe 201 and coolant outlet pipe 202 arranged at the top and bottom, enables the coolant to flow from top to bottom, thereby coming into contact with the ammonia gas containing water vapor and condensing the ammonia gas. The uncondensed gas can be discharged to the outside through the outlet valve 103.

[0055] Example 3:

[0056] Please see Figures 3-5 This is the third embodiment of the present utility model.

[0057] Specifically, an ammonia condensation assembly 3 is installed inside the shrinkage housing 101. The ammonia condensation assembly 3 includes: two sets of support cover plates 303 disposed inside the shrinkage housing 101; and a spiral tube 301 fixed between the support cover plates 303.

[0058] Furthermore, the spiral tube 301 is used for ammonia flow. The spiral tube 301 can be made of a material with high thermal conductivity, which can quickly cool the ammonia inside the spiral tube 301.

[0059] Specifically, the spiral tube 301 is circumferentially distributed along the axis of the reducer housing 101.

[0060] Furthermore, multiple sets of spiral tubes 301 are arranged in a spiral coil between two sets of support cover plates 303, allowing ammonia gas to flow normally through multiple spiral tubes 301.

[0061] Specifically, the cooling chamber 203 is located between two sets of support cover plates 303, and a high-temperature resistant sealing ring is provided between the support cover plate 303 and the shrinkage unit housing 101.

[0062] Furthermore, a high-temperature resistant sealing ring is used to seal the support cover plate 303 and the reducer housing 101 to prevent ammonia gas from entering between the support cover plate 303 and the reducer housing 101.

[0063] Specifically, a connection hole 302 corresponding to the spiral tube 301 is provided at the connection between the support cover plate 303 and the spiral tube 301.

[0064] Furthermore, connection hole 302 is used for ammonia gas inlet.

[0065] In use, ammonia gas enters the spiral tube 301 through the bottom connection hole 302 and moves upward along the spiral tube 301. The spiral tube 301 is spirally coiled between two sets of support cover plates 303, which can increase the residence time of ammonia gas in the spiral tube 301, so that the ammonia gas can fully contact the coolant in the cooling chamber 203, and achieve efficient cooling of ammonia gas.

[0066] In summary, by using the ammonia condensation component 3, multiple spiral tubes 301 are arranged in a spiral coil between the two sets of support cover plates 303, which can increase the residence time of ammonia in the spiral tubes 301, allowing the ammonia to fully contact the coolant in the cooling chamber 203.
