Description

Technical Field

[0001] This utility model relates to the technical field of chemical production, specifically to a high-efficiency chilled water supply device. Background Technology

[0002] Hydrogen cyanide (HCN) has numerous applications as a reactant or synthetic intermediate in various synthetic pathways. In particular, it is used to prepare acetone cyanohydrin (used in the production of methyl methacrylate (MAM), such as PMMA (Altuglas). ® Plexiglas ® Hydrogen cyanide is a key reactant in the synthesis of methionine, a basic monomer of thermoplastic polymers, or as a synthetic intermediate for adiponitrile, which is essential for the preparation of polyamide 6.6 (Nylon). ® ) and synthetic intermediates of many chelating agents.

[0003] In our company's HCN system used for producing hydrogen cyanide, the source of 0°C chilled water is a screw chiller unit. The screw chiller unit uses electricity as an energy source to produce 0°C chilled water. In many years of production practice, the unit has been operating relatively stably, but it has the disadvantage of high energy consumption. Since a large amount of surplus steam is generated during the production process of various chemical products in our company, we are now using this surplus steam to heat the generator in the lithium bromide system to produce 0°C chilled water, replacing the screw chiller unit and solving the problem of high energy consumption of the screw chiller unit.

[0004] The generator's function is to heat and evaporate the water in dilute lithium bromide to obtain concentrated lithium bromide, which is then supplied to other devices in the lithium bromide system for producing 0°C chilled water. However, existing generators typically introduce dilute lithium bromide directly through the inlet, and then heat the lithium bromide within the generator to evaporate the water. Since the dilute lithium bromide introduced into the generator requires a certain heating time to reach its boiling point and evaporate the water, the efficiency of producing concentrated lithium bromide is relatively low. Utility Model Content

[0005] The present invention aims to provide a power supply device for producing chilled water at high efficiency, which can improve the efficiency of producing concentrated lithium bromide.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: 1) A high-efficiency chilled water production source supply device, comprising a chamber body, an outlet pipe for concentrated lithium bromide to flow out of the chamber body at the bottom of the chamber body, a vent pipe for water vapor to be discharged from the chamber body at the top of the chamber body, a multi-layer heating structure inside the chamber body, a rotating spray structure for spraying dilute lithium bromide inside the chamber body, the spray structure being located above the heating structure, and a stirring element for stirring the dilute lithium bromide connected to the bottom of the spray structure.

[0007] In this invention, dilute lithium bromide is sprayed into the chamber via a spray structure. Upon contact with the top heating structure, the sprayed lithium bromide rapidly heats up, causing some moisture to evaporate. This moisture then drips onto the lower heating structure, where it evaporates again. When the lithium bromide in the chamber submerges the lower heating structure, the lower heating structure continues to heat and evaporate moisture from the lithium bromide at the bottom of the chamber. The sprayed lithium bromide continues to contact the unsubmerged heating structures, rapidly heating and evaporating some moisture, until the lithium bromide in the chamber submerges the top heating structure. At this point, the lithium bromide introduction is complete. The heating structure then heats the entire lithium bromide in the chamber, rapidly evaporating the moisture to obtain concentrated lithium bromide, which then flows out through the outlet pipe. During this process, the moisture evaporated from the dilute lithium bromide turns into water vapor and is discharged from the chamber through the vent pipe.

[0008] By rotating the spray structure, dilute lithium bromide can be sprayed more evenly into the chamber and fully contact the heating structure on the top layer. This allows the dilute lithium bromide to heat up more quickly and evaporate some of the moisture as it enters the chamber. At the same time, the spray structure drives the agitator to rotate, which stirs the dilute lithium bromide in the chamber, ensuring that the dilute lithium bromide is heated evenly and promoting the evaporation of moisture from the dilute lithium bromide to obtain concentrated lithium bromide.

[0009] In summary, by using a rotary spraying structure to spray dilute lithium bromide in conjunction with a multi-layer heating structure, the dilute lithium bromide can be rapidly heated and some of its moisture evaporated as it enters the chamber. Then, the heating structure, together with the stirring element, heats the entire dilute lithium bromide in the chamber, rapidly evaporating the moisture to obtain concentrated lithium bromide, thus improving the overall efficiency of concentrated lithium bromide production.

[0010] 2) A power supply device for efficiently producing chilled water according to 1), wherein: The heating structure includes several serpentine bends arranged in a serpentine pattern, which are arranged sequentially from bottom to top within the chamber. The serpentine bends are fixedly connected to the inner wall of the chamber. All adjacent serpentine bends are connected by a first straight pipe. The structure also includes an inlet pipe for excess steam to enter the serpentine bends and an outlet pipe for excess steam to exit the serpentine bends. The inlet pipe passes through the chamber and connects to the lowest serpentine bend, and the outlet pipe passes through the chamber and connects to the uppermost serpentine bend.

[0011] In this invention, excess steam is introduced into the lowest serpentine bend through the inlet pipe. This excess steam then flows through a first straight pipe into several upper serpentine bends until reaching the highest bend, and finally exits through the outlet pipe. As the excess steam flows within the serpentine bends and the first straight pipe, the heating of these pipes warms the dilute lithium bromide within the chamber. This heating method, utilizing excess steam generated during the production of various chemical products, saves energy.

[0012] Simultaneously, lithium bromide is sprayed into the chamber through a spray structure. The sprayed lithium bromide first contacts the uppermost serpentine bend, where it is heated rapidly, causing some moisture to evaporate. The moisture then drips into the lower serpentine bend, where it evaporates some more. When the dilute lithium bromide in the chamber submerges the lower serpentine bend, the lower serpentine bend and the first straight pipe continue to heat and evaporate moisture from the dilute lithium bromide at the bottom of the chamber. The sprayed lithium bromide continues to contact the unsubmerged serpentine bends, rapidly heating and evaporating some moisture, until the dilute lithium bromide submerges the uppermost serpentine bend. At this point, the dilute lithium bromide has been introduced. The serpentine bend and the first straight pipe then heat the entire dilute lithium bromide in the chamber, rapidly evaporating the moisture to obtain concentrated lithium bromide. By using several serpentine bends arranged sequentially from bottom to top, the process of spraying dilute lithium bromide into the chamber via the spray structure can rapidly heat up the dilute lithium bromide and evaporate some of the moisture, thereby improving the overall efficiency of producing concentrated lithium bromide.

[0013] 3) A power supply device for efficiently producing chilled water according to 1), wherein: The spray structure includes a second straight pipe passing through the top of the chamber, which is rotatably connected to the chamber. The upper end of the second straight pipe is connected to an inlet pipe for dilute lithium bromide to flow into the second straight pipe. The second straight pipe is rotatably connected to the inlet pipe, which is fixedly installed on the top of the chamber. The lower end of the second straight pipe is fixedly connected to and connected to a nozzle for spraying lithium bromide. The top of the chamber is provided with a drive unit for driving the second straight pipe to rotate.

[0014] In this invention, dilute lithium bromide is introduced into the second straight pipe through the inlet pipe. The dilute lithium bromide introduced into the second straight pipe is sprayed into the chamber from the nozzle. At the same time, the second straight pipe is driven to rotate by the drive component, and the second straight pipe drives the nozzle to rotate. During the rotation of the nozzle, the dilute lithium bromide can be sprayed into the chamber more evenly and make full contact with the serpentine bend. Thus, during the process of the dilute lithium bromide entering the chamber, the dilute lithium bromide is rapidly heated and some of the water evaporates, thereby improving the overall efficiency of producing concentrated lithium bromide.

[0015] 4) A power supply device for efficiently producing chilled water according to 3), wherein: The drive unit includes a motor mounted on the top of the chamber, the output shaft of the motor is fixedly connected to a first bevel gear, the first bevel gear meshes with a second bevel gear, and the second bevel gear is fixedly connected to a second straight pipe.

[0016] In this invention, a motor drives a first bevel gear to rotate, which in turn drives a second bevel gear to rotate. The second bevel gear then drives a second straight pipe to rotate, which in turn drives a nozzle to rotate. During the rotation of the nozzle, the dilute lithium bromide can be sprayed more evenly into the chamber, ensuring that the sprayed lithium bromide makes full contact with the serpentine bend. As a result, the dilute lithium bromide heats up rapidly and evaporates some of its moisture as it enters the chamber, thus improving the overall efficiency of producing concentrated lithium bromide.

[0017] 5) A power supply device for efficiently producing chilled water according to 1), wherein: The agitator includes an agitator rod, one end of which is fixedly connected to the bottom of the nozzle, and the other end of which is rotatably connected to the bottom of the chamber. Several agitator blades for agitating dilute lithium bromide are symmetrically fixedly connected to the agitator rod, and the several agitator blades are located between several serpentine bends.

[0018] In this invention, during the process of the motor driving the nozzle to rotate, the nozzle drives the stirring rod to rotate, and the stirring rod drives the stirring blade to rotate. During the rotation of the stirring blade, the dilute lithium bromide in the chamber can be stirred, so that the dilute lithium bromide is heated evenly and promotes the evaporation of moisture in the dilute lithium bromide.

[0019] Compared with the prior art, this utility model also has the following technical effects: In this invention, after excess steam is introduced into the air inlet pipe to heat the serpentine bend and the first straight pipe, dilute lithium bromide is introduced into the second straight pipe and the nozzle through the liquid inlet pipe. Simultaneously, the motor is started to drive the second straight pipe and the nozzle to rotate. During rotation, the nozzle evenly sprays dilute lithium bromide into the chamber. The lithium bromide sprayed into the chamber first comes into full contact with the uppermost serpentine bend, where it is heated rapidly, causing some moisture to evaporate. The moisture then drips onto the lower serpentine bend and evaporates again. The accumulated dilute lithium bromide in the chamber submerges the lower serpentine bend. The lower serpentine bend and the first straight pipe continuously heat and evaporate the moisture in the dilute lithium bromide at the bottom of the chamber. The dilute lithium bromide sprayed into the chamber continues to contact the unsubmerged serpentine bend, rapidly heating up and evaporating some of the moisture, until the dilute lithium bromide submerges the uppermost serpentine bend. At this point, the dilute lithium bromide has been introduced. The serpentine bend and the first straight pipe heat up the dilute lithium bromide in the chamber as a whole. At the same time, the dilute lithium bromide is stirred by the stirring rod and stirring blades that rotate with the nozzle, so that the dilute lithium bromide is heated evenly and the moisture in the dilute lithium bromide is rapidly evaporated to obtain concentrated lithium bromide.

[0028] See the example. Figure 1 and Figure 2 As shown, this embodiment is a high-efficiency chilled water production source device, including a chamber 1. The bottom of the chamber 1 is connected to an outlet pipe 2 for concentrated lithium bromide to flow out of the chamber 1. An outlet control valve is installed on the outlet pipe 2. The top of the chamber 1 is connected to a vent pipe 3 for water vapor to be discharged from the chamber 1. A bracket is welded to the top of the chamber 1, and an inlet pipe 9 for dilute lithium bromide to flow into a second straight pipe 8 is welded to the bracket. The second straight pipe 8 is rotatably connected to the inlet pipe 9 via a rotary joint. The second straight pipe 8 is connected to the inlet pipe 9. The other end of the second straight pipe 8 passes through the top of the chamber 1 and is welded to a spray nozzle. The lithium bromide nozzle 10 and the second straight tube 8 are rotatably connected to the top of the chamber 1 via bearings. A stirring rod 14 is welded to the bottom of the nozzle 10. The bottom of the stirring rod 14 is rotatably connected to the bottom of the chamber 1 via bearings. A stirring blade 15 is symmetrically welded to the stirring rod 14. The stirring blade 15 is located between two serpentine bends 4. A motor 11 is fixedly installed on the top of the chamber 1 via bolts and nuts. The output shaft of the motor 11 is fixedly connected to a first bevel gear 12 via bolts and nuts. The first bevel gear 12 meshes with a second bevel gear 13. The second bevel gear 13 is welded to the second straight tube 8.

[0029] Two serpentine bends 4 with a serpentine structure are arranged sequentially from bottom to top inside the chamber 1. The lower serpentine bend 4 is welded and fixed to the bottom of the chamber 1, and the upper serpentine bend 4 is welded and fixed to the inner wall of the chamber 1. Both serpentine bends 4 are located below the nozzle 10. A first straight pipe 5 connects the two serpentine bends 4. The chamber also includes an air inlet pipe 6 for excess steam to enter the serpentine bend 4 and an air outlet pipe 7 for excess steam to exit the serpentine bend 4. The air inlet pipe 6 passes through the chamber 1 and connects to the lower serpentine bend 4, and the air outlet pipe 7 passes through the chamber 1 and connects to the upper serpentine bend 4.

[0030] In this embodiment, excess steam is introduced into the lower serpentine bend 4 through the air inlet pipe 6, and then the excess steam enters the upper serpentine bend 4 through the first straight pipe 5, and finally exits from the air outlet pipe 7. During the flow of excess steam in the serpentine bend 4 and the first straight pipe 5, the serpentine bend 4 and the first straight pipe 5 are heated. At this time, dilute lithium bromide is introduced into the second straight pipe 8 through the liquid inlet pipe 9. The dilute lithium bromide introduced into the second straight pipe 8 is sprayed into the chamber 1 from the nozzle 10. At the same time, the first bevel gear 12 is driven to rotate by the motor 11. The first bevel gear 12 drives the second bevel gear 13 to rotate. The second bevel gear 13 drives the second straight pipe 8 to rotate. The second straight pipe 8 drives the nozzle 10 to rotate. The nozzle 10 drives the stirring rod 14 to rotate. The stirring rod 14 drives the stirring blade 15 to rotate.

[0031] During the rotation of the nozzle 10, the nozzle 10 can spray the dilute lithium bromide more evenly into the chamber 1, ensuring full contact between the dilute lithium bromide and the upper serpentine bend 4. The lithium bromide is rapidly heated by the upper serpentine bend 4, causing some moisture to evaporate. This moisture then drips onto the lower serpentine bend 4, where it evaporates again. When the dilute lithium bromide in the chamber 1 submerges the lower serpentine bend 4, the lower serpentine bend 4 and the first straight pipe 5 continuously heat and evaporate moisture from the dilute lithium bromide at the bottom of the chamber 1. The dilute lithium bromide sprayed into the chamber 1 continues to... The lithium bromide comes into contact with the upper serpentine bend 4, rapidly heating up and evaporating some of the moisture until the dilute lithium bromide submerges the upper serpentine bend 4. At this point, the dilute lithium bromide has been introduced completely. The lithium bromide in the chamber 1 is then heated as a whole through the serpentine bend 4 and the first straight pipe 5. Simultaneously, the dilute lithium bromide is stirred by the stirring rod 14 and stirring blade 15 rotating with the nozzle 10, ensuring uniform heating and rapid evaporation of the moisture in the dilute lithium bromide to obtain concentrated lithium bromide. Then, the liquid outlet control valve is opened, allowing the concentrated lithium bromide to flow out from the liquid outlet pipe 2. During the above process, the moisture evaporated from the dilute lithium bromide turns into water vapor and is discharged from the chamber 1 through the vent pipe 3.

[0032] In summary, by using the rotating nozzle 10 to spray dilute lithium bromide in conjunction with two serpentine bends 4 through which excess steam is introduced, the dilute lithium bromide can be rapidly heated and some moisture evaporated during its entry into the chamber 1. Then, the serpentine bends 4 and the first straight pipe 5, together with the rotating stirring blades 15, heat the dilute lithium bromide in the chamber 1 as a whole, rapidly evaporating the moisture in the dilute lithium bromide to obtain concentrated lithium bromide. This improves the overall efficiency of concentrated lithium bromide production. Furthermore, by utilizing the excess steam generated during the production of various chemical products for heating, energy consumption is saved.
