Description

Technical Field

[0001] This utility model relates to the field of chemical distillation technology, specifically a chemical distillation apparatus. Background Technology

[0002] Distillation utilizes the differences in volatility of components in a mixture. Through counter-current multi-stage contact between the liquid and gas phases, driven by thermal energy and constrained by phase equilibrium, the more volatile components are transferred from the liquid phase to the gas phase, while the less volatile components are transferred from the gas phase to the liquid phase, thus achieving the separation of the mixture. This process takes place in a distillation column, which is equipped with trays or packing, allowing the rising vapor to come into contact with and transfer mass with the descending condensate multiple times, gradually improving the purity of the product.

[0003] An investigation revealed a Chinese utility model patent (Publication No.: CN212881101U) disclosing a chemical distillation apparatus, comprising a working chamber, a distillation tank, a reboiler, and a condensate tank. A support frame is installed on the bottom side of the working chamber, and support devices are provided on the support frame and the inner wall of the working chamber. The distillation tank and the reboiler are both mounted on the support devices. A heater (Type 1) and a heater (Type 2) are located at the bottom inside the working chamber, respectively positioned below the distillation tank and the reboiler. This utility model relates to the field of chemical distillation technology. This chemical distillation apparatus achieves the purpose of multiple distillations of the chemical raw material. The separate design of the heater from the distillation tank and reboiler facilitates subsequent heater replacement and allows for adjustments to the heater's power specifications as needed. Multiple distillations effectively ensure the quality of the distillation, and the integrated multiple distillation process helps reduce contamination of the internal components of the chemical distillation apparatus due to external factors, thus guaranteeing the quality of the distillation.

[0004] Although the aforementioned patent effectively ensures the quality of distillation through the design of structures such as reflux output pipes and reboiling steam pipes, and integrated multi-distillation helps reduce contamination of the internal parts of the chemical distillation unit due to external factors, thus guaranteeing the quality of distillation, the chemical distillation unit still requires the vaporized chemical raw materials to be transported and condensed in the condenser before subsequent operations are performed. This process takes time for steam transport, leading to a decrease in the efficiency of chemical distillation and consequently, a reduction in the overall efficiency of chemical distillation production.

[0005] Therefore, this utility model provides a chemical distillation apparatus to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a chemical distillation apparatus, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: a chemical distillation apparatus, comprising a distillation tank, wherein a guiding condensation mechanism is installed inside the distillation tank, and a secondary distillation mechanism is installed on the surface of the distillation tank;

[0010] The guiding condensation mechanism includes a water collection box fixedly connected to the upper surface of the distillation tank. The water collection box contains coolant. Connecting pipes are fixedly connected to both sides of the water collection box. A circulation pump is fixedly connected to one side of the distillation tank. One end of each of the two connecting pipes is connected to the output and input ends of the circulation pump, respectively. A guide plate is fixedly connected inside the water collection box. An installation plate is fixedly connected inside the distillation tank. A gas guide fan is installed on the upper surface of the installation plate. A guide plate is fixedly connected to the middle of the inner wall of the distillation tank. The guide plate is connected to the distillation tank and corresponds to the guide plate.

[0011] As a preferred technical solution of this application, the upper surface of the water collection box is fixedly connected with a liquid inlet pipe, the guide plate corresponds to the gas guide fan, and the interior of the distillation tank is provided with four corresponding steam guide holes, two of which correspond to the gas guide fan and the other two of which correspond to the guide plate.

[0012] As a preferred technical solution of this application, the secondary distillation mechanism includes two connecting pipes respectively fixedly connected to both sides of the surface of the distillation tank. The connecting pipes are connected to corresponding steam guide holes. A reboiling box is sleeved on the surface of the connecting pipes. A conical plate is fixedly connected inside the reboiling box. The conical plate corresponds to the connecting pipe.

[0013] As a preferred technical solution of this application, the secondary distillation mechanism further includes a heat-conducting pipe fixedly connected to the lower surface of the reboiler.

[0016] (III) Beneficial Effects

[0017] By incorporating a guiding condensation mechanism and other structural elements, the chemical raw materials inside the distillation tank are heated by a heater to generate steam. A steam guide fan is then activated to direct the steam to the guide plate. Cooling of the guide plate by a coolant causes the steam to condense into water droplets upon contact with it, falling onto the guide plate and then through the steam guide holes into the reboiler. The secondary distillation mechanism then further distills the chemical raw materials, allowing the steam generated from the chemical raw materials to condense directly inside the distillation tank, avoiding the need for steam transportation and subsequent condensation. This significantly improves the efficiency of chemical raw material distillation.

[0018] By incorporating a secondary distillation mechanism and other structural elements, after the distilled and condensed chemical raw materials enter the reboiler, the heat from the heater is transferred to the reboiler through the cooperation of the heater and heat pipes. This reheats the chemical raw materials and generates steam, which then enters the interior of the distillation tank through corresponding steam guide holes. The steam guide fan and baffle plate work together to further distill the chemical raw materials. This not only improves the distillation effect of the chemical raw materials but also allows for repeated distillation of the chemical raw materials using a separate heater, reducing resource waste.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a chemical distillation apparatus, such as... Figures 1-4 As shown, the chemical distillation apparatus includes a distillation tank 1. A feed pipe is fixedly connected to one side of the distillation tank 1, and chemical raw materials are placed inside the distillation tank 1. A guiding condensation mechanism is installed inside the distillation tank 1. The guiding condensation mechanism includes a water collection box 2 fixedly connected to the upper surface of the distillation tank 1. A liquid inlet pipe is fixedly connected to the upper surface of the water collection box 2. The liquid inlet pipe facilitates the addition of coolant to the inside of the water collection box 2.

[0027] The water collection box 2 is filled with coolant. Connecting pipes 3 are fixedly connected to both sides of the water collection box 2. A circulation pump 4 is fixedly connected to one side of the distillation tank 1. One end of each of the two connecting pipes 3 is connected to the output end and the input end of the circulation pump 4, respectively. By setting up the circulation pump 4, the coolant circulates in the connecting pipes 3 and inside the water collection box 2, thereby avoiding the coolant from continuously condensing the steam and reducing the effect of the coolant.

[0028] A guide plate 5 is fixedly connected inside the water collection box 2, and an installation plate 6 is fixedly connected inside the distillation tank 1. A gas guide fan 7 is installed on the upper surface of the installation plate 6. The guide plate 8 corresponds to the gas guide fan 7. The heater 16 is started to heat the chemical raw materials to generate steam. The gas guide fan 7 is started to guide the steam so that the steam comes into contact with the guide plate 5.

[0029] A guide plate 8 is fixedly connected to the middle of the inner wall of the distillation tank 1. Four corresponding steam guide holes 9 are opened inside the distillation tank 1. Two of the steam guide holes 9 correspond to the steam guide fan 7, and the other two steam guide holes 9 correspond to the guide plate 8. The guide plate 8 is connected to the distillation tank 1 and corresponds to the flow guide plate 5. A secondary distillation mechanism is installed on the surface of the distillation tank 1. The secondary distillation mechanism also includes a heater 16 set on the lower surface of the distillation tank 1. A support base plate 17 is fixedly connected to the lower surface of the heater 16. Two heat conduction pipes 13 correspond to the heater 16 and correspond to the conical plate 12. The upper surface of the support base plate 17 is fixedly connected to support plates 18 in a ring array. The upper surfaces of several support plates 18 are fixedly connected to two corresponding arc plates 19. Both arc plates 19 are in contact with the distillation tank 1. Through the cooperation of the support plates 18 and the arc plates 19, the distillation tank 1 is supported, so that the distillation tank 1 is more stable during use.

[0030] The secondary distillation mechanism includes two connecting pipes 10 that are fixedly connected to both sides of the surface of the distillation tank 1. The connecting pipes 10 are connected to the corresponding steam guide holes 9. Due to the setting of the coolant, the temperature of the guide plate 5 is low, so that the steam condenses into water droplets on the surface of the guide plate 5 and is guided by the guide plate 5, so that the water droplets fall into the guide plate 8, and thus the water droplets enter the interior of the connecting pipe 10 through the corresponding steam guide holes 9, so that the steam condensation efficiency is higher.

[0031] A reboiler 11 is fitted onto the surface of the connecting pipe 10. A conical plate 12 is fixedly connected inside the reboiler 11, corresponding to the connecting pipe 10. The secondary distillation mechanism also includes a heat-conducting pipe 13 fixedly connected to the lower surface of the reboiler 11. A fixing plate 14 is fitted onto the surface of the heat-conducting pipe 13. After the chemical raw material enters the interior of the connecting pipe 10, the conical plate 12 causes the chemical raw material to be distributed around the bottom wall of the reboiler 11. The heat from the heater 16 is transferred to the interior of the reboiler 11 through the heat-conducting pipe 13 and contacts the conical plate 12, thereby reheating the chemical raw material. The fixing plate 14 is fixedly connected to the distillation tank 1 and the reboiler 11. An exhaust pipe 15 is fixedly connected to one side of the reboiler 11 and is connected to the corresponding steam guide hole 9.

[0032] Specifically, when this chemical distillation apparatus is in use: chemical raw materials are placed inside the distillation tank 1, the heater 16 is started to heat the chemical raw materials to generate steam, the steam guide fan 7 is started to guide the steam so that the steam comes into contact with the guide plate 5. Due to the setting of the coolant, the temperature of the guide plate 5 is low, so the steam condenses into water droplets on the surface of the guide plate 5. The water droplets are guided by the guide plate 5 and fall onto the guide plate 8. The water droplets then enter the interior of the connecting pipe 10 through the corresponding steam guide hole 9, so that the steam condensation efficiency is higher.

[0033] When the condensed chemical raw material enters the interior of the connecting pipe 10, the conical plate 12 distributes the chemical raw material around the bottom wall of the reboiling tank 11. The heat from the heater 16 is transferred to the interior of the reboiling tank 11 through the heat pipe 13 and comes into contact with the conical plate 12, thereby reheating the chemical raw material. This causes the chemical raw material to vaporize again and enter the interior of the distillation tank 1 through the corresponding steam guide hole 9. After mixing with the steam generated inside the distillation tank 1, the mixture comes into contact with the guide plate 5 again through the steam guide fan 7, thereby performing multiple distillations on the chemical raw material and improving the distillation effect.

[0034] 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.
