Technical Field
[0001] This utility model relates to the field of condensation equipment technology, and in particular to a built-in plate distillation column condenser. Background Technology
[0002] In the distillation process of industries such as chemical and pharmaceutical, the distillation column condenser is a key piece of equipment, and its performance directly affects the distillation efficiency and product quality.
[0003] Some traditional condensers typically employ a single condensation method, such as shell-and-tube or plate condenser structures, which have limited heat exchange efficiency. Furthermore, the installation and disassembly of some equipment are quite complex, and maintenance is inconvenient. To address these issues, this invention provides a built-in plate distillation column condenser. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a built-in plate distillation column condenser.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A built-in plate distillation column condenser includes a distillation column body, condenser tubes, and a fixing assembly. A first sealing groove is formed at the upper end of one side of the condenser tubes, and a cold water pipe is fixedly installed inside the first sealing groove. A second sealing groove is formed at the lower end of one side of the condenser tubes, and a hot water pipe is fixedly installed inside the second sealing groove. A spiral heat exchange tube is fixedly connected between the cold water pipe and the hot water pipe, and the spiral heat exchange tube is located inside the condenser tubes. A connecting pipe is fixedly connected to the upper end of the distillation column body, and a first reducing pipe is fixedly connected to the other end of the connecting pipe. A connecting plate is fixedly connected to the lower end of the first reducing pipe and the upper end of the condenser tubes. A second reducing pipe is fixedly connected to the lower end of the condenser tubes, and a condensation assembly is fixedly connected to the lower end of the second reducing pipe.
[0007] As a further improvement of this utility model, the fixing component includes a first fixing ring, and a second fixing ring is rotatably connected to one side of the first fixing ring via a hinge. Both the first fixing ring and the second fixing ring have snap-fit grooves adapted to the connecting plate inside. Both the first fixing ring and the second fixing ring have connecting blocks fixedly connected to their front sides. One side of one connecting block has a first threaded hole, and the other side of the connecting block has a first through hole. A fixing bolt adapted to the first threaded hole is inserted into the first through hole.
[0008] As a further improvement of this utility model, the condensation assembly includes a sleeve fixedly connected to the lower end of the second reducing pipe. An installation pipe is inserted into the inside of the sleeve, and several baffles are fixedly connected inside the installation pipe. A flange is fixedly connected to the lower end of both the sleeve and the installation pipe. Several second threaded holes are opened at the upper end of one flange, and several second through holes are opened at the upper end of the other flange. Mounting bolts that are compatible with the second threaded holes are inserted into the inside of each of the second through holes. A knob is fixedly connected to one end of both the fixing bolt and the mounting bolt.
[0009] As a further improvement of this utility model, a third reducing pipe is fixedly connected to the lower end of the mounting pipe, and a liquid outlet pipe is fixedly connected to the lower end of the third reducing pipe.
[0010] As a further improvement of this utility model, the upper diameter of the first variable diameter tube is smaller than the lower diameter, the upper diameter of the second variable diameter tube is smaller than the lower diameter, and the upper diameter of the third variable diameter tube is larger than the lower diameter.
[0011] As a further improvement of this utility model, a sealing gasket is provided on the opposite side of both connecting discs.
[0012] The beneficial effects of this utility model are:
[0013] By installing a condensation assembly, during operation, the cold water in the cold water pipe exchanges heat with the steam through a spiral heat exchange tube. The spiral structure increases the heat exchange area, making heat transfer more complete and rapidly reducing the steam temperature for efficient condensation. At the same time, the baffles installed inside the tube can change the flow direction of the condensed liquid, prolonging the residence time of the liquid in the condensation assembly, further enhancing the condensation effect, ensuring that the steam is fully converted into liquid, and improving the working efficiency of the entire distillation column condensation system.
[0014] By setting up a fixing component, the device uses multiple reducing pipes to connect various parts during use, allowing components with different pipe diameters to be smoothly connected and facilitating overall assembly. The fixing component is secured to the connecting plate by a first fixing ring and a second fixing ring, and then fixed with fixing bolts. The condensing component is connected by a flange and mounting bolts. The connection method is simple to operate and easy to disassemble. When it is necessary to clean, repair or replace components such as condensing pipes and condensing components, disassembly and assembly can be completed quickly, shortening equipment maintenance time and reducing maintenance costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figures 1-3 A built-in plate distillation column condenser includes a distillation column body 1, a condenser tube 2, and a fixing assembly. A first sealing groove is formed at the upper end of one side of the condenser tube 2, and a cold water pipe 3 is fixedly installed inside the first sealing groove. A second sealing groove is formed at the lower end of one side of the condenser tube 2, and a hot water pipe 4 is fixedly installed inside the second sealing groove. A spiral heat exchange tube 5 is fixedly connected between the cold water pipe 3 and the hot water pipe 4, and the spiral heat exchange tube 5 is located inside the condenser tube 2. A connecting pipe 6 is fixedly connected to the upper end of the distillation column body 1, and a first reducing pipe 7 is fixedly connected to the other end of the connecting pipe 6. A connecting plate 8 is fixedly connected to the lower end of the first reducing pipe 7 and the upper end of the condenser tube 2. A second reducing pipe 9 is fixedly connected to the lower end of the condenser tube 2, and a condensation assembly is fixedly connected to the lower end of the second reducing pipe 9.
[0021] In this utility model, the fixing component includes a first fixing ring 10, and a second fixing ring 11 is rotatably connected to one side of the first fixing ring 10 via a hinge. Both the first fixing ring 10 and the second fixing ring 11 have snap-fit grooves 12 that are adapted to the connecting plate 8. Both the first fixing ring 10 and the second fixing ring 11 have connecting blocks 13 fixedly connected to their front sides. One side of one connecting block 13 has a first threaded hole, and the other side of the connecting block 13 has a first through hole. A fixing bolt 14 adapted to the first threaded hole is inserted into the first through hole.
[0022] The condenser assembly includes a sleeve 15 fixedly connected to the lower end of the second reducing pipe 9. An installation pipe 16 is inserted inside the sleeve 15. Several baffles 17 are fixedly connected inside the installation pipe 16. These baffles 17 are evenly distributed inside the installation pipe 16. The baffles 17 change the flow direction of the condensed liquid and increase the residence time of the liquid in the installation pipe 16, thereby improving the condensation effect. The lower ends of both the sleeve 15 and the installation pipe 16 are fixedly connected to flanges 18. One flange 18 has several second threaded holes at its upper end, and the other flange 18 has several second through holes at its upper end. The installation bolts 19, which are compatible with the second threaded holes, are inserted into the interior of the second through holes. The specifications of the installation bolts 19 match the second threaded holes. By rotating the installation bolts 19, they can be screwed into the second threaded holes to achieve a tight connection between the two flanges 18. A knob 20 is fixedly connected to one end of both the fixing bolt 14 and the installation bolt 19. The knob 20 allows the operator to directly rotate the bolts by hand for installation and disassembly operations.
[0023] The lower end of the mounting pipe 16 is fixedly connected to a third reducing pipe 21, and the lower end of the third reducing pipe 21 is fixedly connected to a liquid outlet pipe 22. The upper diameter of the first reducing pipe 7 is smaller than the lower diameter. This design of smaller at the top and larger at the bottom allows steam to flow slowly when entering the first reducing pipe 7, improving the condensation effect. The upper diameter of the second reducing pipe 9 is smaller than the lower diameter, and the upper diameter of the third reducing pipe 21 is larger than the lower diameter. The design of larger at the top and smaller at the bottom of the third reducing pipe 21 can further adjust the flow rate and pressure of the liquid, so that the liquid can be discharged smoothly from the condenser assembly. The two connecting plates 8 are provided with sealing gaskets 23 on opposite sides. The sealing gaskets 23 are made of rubber material, which can effectively prevent steam or liquid from leaking at the connection and ensure the sealing performance of the condenser.
[0024] In use, the steam generated by the main body 1 of the distillation column enters the first variable diameter pipe 7 through the connecting pipe 6, and then the steam enters the condenser 2 through the connecting plate 8. The cooling water pipe 3 inputs cooling water into the spiral heat exchanger 5. The cooling water absorbs heat from the steam and heats up during its flow in the spiral heat exchanger 5. The heated hot water is discharged through the hot water pipe 4. The steam condenses into liquid after heat exchange with the spiral heat exchanger 5 in the condenser 2. The condensate enters the sleeve 15 through the second variable diameter pipe 9. The baffle 17 in the mounting pipe 16 guides and buffers the condensate. Then the condensate is discharged through the third variable diameter pipe 21 and the outlet pipe 22 in sequence. The first variable diameter pipe 7 realizes the diffusion of steam, the second variable diameter pipe 9 realizes the diffusion of condensate, and the third variable diameter pipe 21 realizes the collection and accelerated flow of condensate.
[0025] During fixing, the first fixing ring 10 and the second fixing ring 11 are rotated by the hinge so that the snap-fit groove 12 inside them locks the connecting plate 8. Then, the fixing bolt 14 is passed through the first through hole of one of the connecting blocks 13 and screwed into the first threaded hole of the other connecting block 13. Tighten the knob 20 to complete the fixing. The sleeve 15 and the mounting tube 16 are connected by the flange 18. The mounting bolt 19 is passed through the second through hole of one of the flanges 18 and screwed into the second threaded hole of the other flange 18. Tighten the knob 20 to complete the installation.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
