Description

Technical Field

[0001] This utility model relates to the field of vacuum condensation technology, and in particular to a high-efficiency vacuum condensate tank. Background Technology

[0002] In the capsule production process, the gelling tank is a key piece of equipment used to produce the gel solution. During operation, the gelling tank generates high-temperature and high-pressure gas. In order to alleviate the vacuum negative pressure, collect condensate, and adjust the viscosity of the gel solution, the gelling tank needs to be connected to a vacuum condensate tank to cool the high-temperature and high-pressure gas.

[0003] A vacuum condenser, also known as a vacuum condenser, is a vacuum container placed between a vacuum chamber and a pumping system to condense large amounts of water vapor.

[0004] However, in the existing technology, vacuum condensate tanks have obvious cooling efficiency problems. In actual operation, high-temperature and high-pressure gas is introduced into the tank in a confined manner, and the gas turbulence cannot be uniformly contacted with the condenser tubes. Moreover, the contact time with the condenser tubes is insufficient, and the high-temperature and high-pressure gas cannot be cooled quickly, resulting in low overall cooling efficiency of the vacuum condensate tank. Utility Model Content

[0005] To address the technical problem of rapid condensation caused by turbulent high-temperature and high-pressure gas flow, this invention provides a high-efficiency vacuum condensate tank.

[0006] The technical solution of this utility model is achieved through the following scheme: a high-efficiency vacuum condensate tank, including a support frame, an inner condenser cylinder, an outer auxiliary condenser cylinder and a flow guiding device, wherein the outer auxiliary condenser cylinder is sleeved on the inner condenser cylinder, the inner condenser cylinder and the outer auxiliary condenser cylinder are mounted on the support frame, the bottom pipe of the inner condenser cylinder is connected to a liquid collection tank, and the inner condenser cylinder is provided with a flow guiding device.

[0007] The inner condenser includes an inner condenser tube, the flow guiding device is located below the inner condenser tube, and a steam inlet pipe is connected to the inner condenser tube, the steam inlet pipe being located between the inner condenser tube and the flow guiding device;

[0008] The external auxiliary condenser cylinder is equipped with an outer condenser tube, which is connected to the inner condenser tube.

[0009] Through the above technical solutions, the condensation process in the upper region is specifically enhanced by the external auxiliary condenser, allowing the steam to fully condense during its ascent, accelerating the cooling rate of the steam. The refrigerant circulates between the inner and outer condenser tubes, making the temperature distribution within the entire device more uniform and avoiding localized excessively high or low temperatures. This not only improves the condensation effect but also effectively reduces the thermal stress caused by excessive temperature gradients, extending the service life of the device. The flow guiding device not only guides the steam, allowing it to contact the inner condenser tube more evenly, but also guides the condensate after condensation, ensuring that the condensate flows smoothly into the collection tank.

[0010] Preferably, the inner condenser also includes an inner cylinder and several baffles. The inner condenser tube is spirally attached to the inner wall of the inner cylinder, and several baffles are arranged in a ring array on the inner wall of the inner cylinder. The ends of the baffles are located in the spiral gaps of the inner condenser tube.

[0011] Preferably, the lower surface of the baffle plate is provided with a plurality of inverted protrusions.

[0012] The above technical solution uses several baffles to divert and obstruct the steam flow, changing the direction of steam flow and increasing the contact opportunity between the steam and the condenser tube. This allows for more complete condensation of the steam, reducing the amount of uncondensed steam remaining. The convex shape increases the steam flow path, prolonging the residence time of the steam below the baffles and increasing the contact time with the condenser tube, thereby improving the condensation effect. At the same time, the convex shape also enhances the local strength of the baffles. During high-speed steam flow and impact, the baffles can better withstand the pressure and impact of the steam, reducing the possibility of deformation and damage, and extending the service life of the baffles.

[0013] Preferably, the steam inlet pipe has several oblique air outlets and several straight air outlets, which are arranged in a cross array. The oblique air outlets face the guide bucket, and the straight air outlets face the condenser inner pipe.

[0014] Preferably, the flow guiding device includes a flow guiding bucket, a flow guiding fan, and a support member. The flow guiding bucket is fixedly installed on the inner cavity of the inner condenser cylinder, and the flow guiding fan is movably mounted on the flow guiding bucket through the support member. The fan blades of the flow guiding fan abut against the flow guiding area of ​​the flow guiding bucket.

[0015] Preferably, the support member is provided with a flow slope on the side near the steam inlet pipe.

[0016] Preferably, a vacuum pump is connected to the top of the inner condenser, a vacuum gauge is provided on the inner condenser, and a first liquid level sensor is provided on the inner condenser below the flow guiding device.

[0017] Through the above technical solution, steam is discharged through the oblique vent. The steam will change its flow direction under the action of the guide bucket, which will then blow the guide fan to rotate. The rotation of the guide fan will drive the steam to flow upward. At the same time, the rotation of the guide fan scrapes the guide bucket's guide area, causing the condensate in the guide area to flow quickly into the storage area and then be discharged into the collection tank. This not only achieves effective guidance of steam, but also ensures that the condensate can be discharged smoothly, avoiding the accumulation or turbulence of condensate in the device.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model uses an external auxiliary condenser to specifically enhance the condensation process in the upper region, allowing the steam to fully condense during its ascent, accelerating the cooling speed of the steam. The refrigerant circulates between the inner and outer condenser tubes, making the temperature distribution within the entire device more uniform and avoiding localized excessively high or low temperatures. This not only improves the condensation effect but also effectively reduces the thermal stress caused by excessive temperature gradients, extending the service life of the device. The flow guiding device not only guides the steam, allowing it to contact the inner condenser tube more evenly, but also guides the condensate after condensation, ensuring that the condensate flows smoothly into the collection tank.

[0020] 2. By using several baffles to divert and obstruct the steam flow, the direction of steam flow is changed, thereby increasing the contact opportunity between the steam and the condenser tube. This allows the steam to condense more fully, reducing the amount of uncondensed steam remaining. The inverted convex shape increases the steam flow path and prolongs the residence time of the steam under the baffles, increasing the contact time with the condenser tube and thus improving the condensation effect. At the same time, the inverted convex shape also enhances the local strength of the baffles. During the high-speed flow and impact of the steam, the baffles can better withstand the pressure and impact of the steam, reducing the possibility of deformation and damage and extending the service life of the baffles.

[0021] 3. Steam exits through the oblique vent. Under the action of the guide bucket, the steam changes its flow direction, which in turn blows the guide fan to rotate. The rotation of the guide fan drives the steam upward. At the same time, the rotation of the guide fan scrapes the guide bucket's guide area, causing the condensate in the guide area to flow quickly into the storage area and then into the collection tank. This not only effectively guides the steam but also ensures that the condensate can be discharged smoothly, avoiding the accumulation or turbulence of condensate in the device.

[0029] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] A high-efficiency vacuum condensate tank, such as Figures 1-6As shown, the device includes a support frame 1, an inner condenser cylinder 2, an outer auxiliary condenser cylinder 3, and a flow guiding device 5. The outer auxiliary condenser cylinder 3 is fitted onto the inner condenser cylinder 2. The inner condenser cylinder 2 and the outer auxiliary condenser cylinder 3 are mounted on the support frame 1. The bottom of the inner condenser cylinder 2 is connected to a liquid collection tank 9, which is equipped with an electric valve. The flow guiding device 5 is installed inside the inner condenser cylinder 2. The inner condenser cylinder 2 includes an inner condenser tube 22. The flow guiding device 5 is located below the inner condenser tube 22. A steam inlet pipe 4 is connected to the inner condenser cylinder 2. The steam inlet pipe 4 is located between the inner condenser tube 22 and the flow guiding device 5, guiding high-temperature and high-pressure steam along a specific path. The flow ensures that the steam comes into full contact with the inner condenser tube 22, increasing the heat exchange area and time between the steam and the inner condenser tube 22. The outer auxiliary condenser 3 is fitted on the upper part of the inner condenser tube 2, and the two work together. The outer auxiliary condenser 3 further absorbs the heat emitted by the inner condenser tube 2, enhancing the overall condensation capacity. This allows the entire device to maintain a good condensation effect even when faced with a large amount of steam or high-temperature steam. The flow guiding device 5 not only guides the steam but also guides the condensate after condensation, ensuring that the condensate can flow smoothly into the collection tank 9, avoiding the accumulation or turbulence of condensate in the device.

[0032] like Figure 1 and Figure 4 As shown, the outer auxiliary condenser 3 is equipped with an outer condenser tube 31, which is connected to the inner condenser tube 22. The outer condenser tube 31 is spirally wound around the upper outer surface of the inner condenser 2 to provide auxiliary cooling for the upper part of the inner condenser 2. This targeted enhancement of the condensation process in this area ensures that the steam can be condensed uniformly and efficiently throughout the condenser, reduces the residue of uncondensed steam, and effectively lowers the temperature of the upper area. The steam undergoes full condensation during its ascent.

[0033] The outer condenser tube 31 is a branch of the inner condenser tube 22. The refrigerant inlet of the outer condenser tube 31 passes through the inner condenser cylinder 2 and is connected to the inner condenser tube 22. The refrigerant outlet of the outer condenser tube 31 is connected to the outlet of the inner condenser tube 22. The refrigerant can form a smooth circulation between the inner condenser tube 22 and the outer condenser tube 31. After the refrigerant enters the inner condenser tube 22 from the inlet, part of it continues to flow in the inner tube, and the other part is diverted to the outer condenser tube 31.

[0034] The refrigerant flows simultaneously in the inner condenser tube 22 and the outer condenser tube 31, making the temperature distribution within the entire device more uniform and avoiding localized excessively high or low temperatures. This improves the condensation effect and the stability of the device. At the same time, the uniform temperature distribution also helps to reduce thermal stress caused by excessive temperature gradients and extend the service life of the device.

[0035] A vacuum pump 8 is connected to the top of the inner condenser cylinder 2. A vacuum gauge 7 is installed on the inner condenser cylinder 2. The vacuum pump 8 is mounted on the support frame 1 to evacuate the cylinder. A first liquid level sensor 6 is installed on the inner condenser cylinder 2 below the flow guiding device 5. The first liquid level sensor 6 is connected to an electric valve. The discharge of condensate can be conveniently controlled by controlling the electric valve. The pipeline connecting the inner condenser cylinder 2 to the collection tank 9 is equipped with not only an electric valve but also a second liquid level sensor 10. The second liquid level sensor 10 detects the lowest liquid level and is also connected to the electric valve.

[0036] like Figure 3 As shown, the inner condenser 2 also includes an inner cylinder 21 and several baffles 23. The inner condenser tube 22 is spirally attached to the inner wall of the inner cylinder 21. Several baffles 23 are arranged in a ring array on the inner wall of the inner cylinder 21. The ends of the baffles 23 are located in the spiral gaps of the inner condenser tube 22. The inner condenser tube 22 is spiral in shape and has gaps between its spiral pipes. Multiple baffles 23 are located on the inner wall of the inner cavity of the inner cylinder 21 and extend through the gaps to divert and obstruct the rising steam, thereby changing the flow direction of the steam and allowing it to fully contact and condense with the inner condenser tube 22.

[0037] like Figure 6 As shown, the lower surface of the baffle plate 23 is provided with several inverted protrusions. These protrusions create multiple obstacles to the rising path of steam, making the steam flow path tortuous. This prolongs the residence time of steam below the baffle plate 23, increases the chance of steam condensing with the condenser inner tube 22, and increases the surface area and local strength of the baffle plate 23. It can disperse the stress generated by steam impact and flow, and reduce the deformation and damage of the baffle plate 23. The baffle plate 23 has a triangular slope on the side facing the top of the inner cylinder 21. Under the action of gravity, the condensate can flow down the slope quickly, preventing the condensate from accumulating on the top of the baffle plate 23 and preventing the condensate from staying for a long time.

[0038] like Figure 5 As shown, the steam inlet pipe 4 has several oblique outlet holes and several straight outlet holes. The oblique outlet holes and the straight outlet holes are arranged in a cross array. The oblique outlet holes face the guide bucket 51, and the straight outlet holes face the inner condenser tube 22, so that the steam is evenly sprayed out from different positions of the steam inlet pipe 4, and the initial distribution in the entire inner condenser tube 2 is more uniform. After the steam is sprayed out from the oblique outlet holes, it will further change the flow direction under the action of the guide bucket 51.

[0039] like Figure 5As shown, the flow guiding device 5 includes a flow guiding bucket 51, a flow guiding fan 52, and a support member 53. The flow guiding bucket 51 is fixedly installed on the inner cavity of the inner condenser cylinder 2. The flow guiding fan 52 is movably mounted on the flow guiding bucket 51 via the support member 53. The fan blades of the flow guiding fan 52 abut against the flow guiding area of ​​the flow guiding bucket 51. Preferably, there are two support members 53 arranged in a cross shape. The rotating part of the bearing of the flow guiding fan 52 is located at the center of the cross shape of the two cross support members 53. The end of the fan blade of the flow guiding fan 52 is adapted to the flow guiding area of ​​the flow guiding bucket 51. The oblique air outlet is... When steam enters the diversion fan 52, it first blows out through the nearest oblique air outlet to rotate the diversion fan 52, and then continues to blow, causing the diversion fan 52 to blow upward. The guide bucket 51 is funnel-shaped, with a larger opening to collect the condensate falling from above more comprehensively, while the smaller bottom outlet facilitates the collection of condensate into the liquid storage area. When the diversion fan 52 rotates, it scrapes the diversion area of ​​the guide bucket 51, causing the condensate in the diversion area to flow quickly into the liquid storage area and then be discharged into the collection tank 9.

[0040] The support 53 is provided with a flow slope on the side near the steam inlet pipe 4. The flow slope has the same function as the triangular ramp to prevent condensate from accumulating.

[0041] Working principle: First, the operator starts the vacuum pump 8 to evacuate the inner condenser 2. At this time, coolant is introduced from the liquid inlet of the inner condenser tube 22. After the coolant flows to the upper part, it branches. Part of it enters the outer condenser tube 31, and part of it remains in the inner condenser tube 22. The refrigerant circulates between the inner condenser tube 22 and the outer condenser tube 31. Further, steam enters the inner condenser 2 through the steam inlet pipe 4. The steam ejected from its oblique outlet first blows the guide fan 52 of the guide device 5 to rotate, and then continues to blow. The rotation of the guide fan 52 drives the steam to flow upward. During the upward flow, the rising steam is diverted and obstructed, changing the direction of steam flow, so that it can fully contact the inner condenser tube 22 for condensation.

[0042] Condensate flows rapidly into the storage area through the guide bucket 51, and then is discharged into the collection tank 9. The liquid level sensor senses and controls the electric valve to drain the liquid.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
