Description

Technical Field

[0001] This utility model relates to the technical field of distillation and condensation apparatus, and in particular to a novel high-efficiency crude product distillation and condensation apparatus. Background Technology

[0002] The main purpose of a crude product distillation condenser is to separate components in a liquid through a distillation process. In this apparatus, the crude product mixture is heated, causing low-boiling-point substances to evaporate. The vapor is then condensed back into a liquid state through a condensation process, achieving separation. This process requires efficient heat transfer and gas-liquid contact to ensure high separation efficiency.

[0003] Traditional crude product distillation and condensation apparatuses generally include basic components such as a heater, a distillation column, and a condenser. The heater heats the crude liquid, evaporation and separation occur in the distillation column, and the condenser cools the vapor and converts it into liquid. Fractionating plates or packing layers within the column enhance the contact between evaporation and condensation, improving separation efficiency. The condenser cools the vapor, condenses it into liquid, and collects it.

[0004] The low distillation efficiency of traditional crude product distillation condensation units is primarily due to relatively low heat and mass transfer efficiencies. Limited heating temperatures, distillation column design, and heat exchange efficiency in the condensation process result in less than ideal evaporation and condensation effects, leading to slow separation and high energy consumption. This not only impacts production efficiency but also increases energy consumption, consequently raising production costs. In some high-efficiency industrial production processes, inefficient distillation processes cannot meet product quality or yield requirements. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new type of high-efficiency crude product distillation and condensation device, which aims to improve the problem that the distillation efficiency of traditional crude product distillation and condensation devices is low and cannot meet the quality or output requirements of the products.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a novel high-efficiency crude product distillation and condensation device, comprising:

[0007] A distillation vessel, wherein the distillation vessel is a hollow cavity with a heating mechanism at the bottom and a steam outlet at the top;

[0008] A spiral condenser tube, which is connected to a steam outlet;

[0012] A cooling water circulation system, comprising a cooling water tank and a circulation pump, wherein the cooling water tank is connected to the cooling jacket of a spiral condenser tube via a pipe.

[0013] As a further description of the above technical solution:

[0015] As a further description of the above technical solution:

[0016] The spiral condenser tube is made of a high thermal conductivity metal material, and the spiral diameter and tube length form a spiral heat exchange structure.

[0018] The connecting pipe has a Y-shaped structure and is connected to the top of the distillation kettle and the middle of the spiral condenser, respectively. An anti-backflow protection valve is installed at the connection point.

[0019] As a further description of the above technical solution:

[0020] The cooling jacket has a double-layer spiral structure, with the cooling water inlet located at the bottom of the spiral condenser tube and the outlet located at the top.

[0021] As a further description of the above technical solution:

[0022] A liquid level sensor is installed at the bottom of the collector, and the liquid level sensor is linked to the circulation pump.

[0023] As a further description of the above technical solution:

[0024] It also includes an intelligent controller that adjusts the power of the heating mechanism and the speed of the circulating pump based on feedback signals from the temperature sensor and the liquid level sensor.

[0025] As a further description of the above technical solution:

[0035] 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.

[0036] Reference Figures 1-3 One embodiment of this utility model is a novel high-efficiency crude product distillation and condensation device, comprising:

[0037] Distillation vessel 1, which is a hollow cavity, with a heating mechanism 2 at the bottom and a steam outlet 3 at the top;

[0038] Spiral condenser 4 is connected to steam outlet 3;

[0039] Collector 5 is connected to the outlet of spiral condenser 4 and is used to receive condensate;

[0040] Temperature sensor 6 is installed at steam outlet 3;

[0041] Vacuum pump 7 is connected to the top of distillation vessel 1 via connecting pipe 8;

[0042] The cooling water circulation system 9 includes a cooling water tank 10 and a circulation pump 11. The cooling water tank 10 is connected to the cooling jacket 12 of the spiral condenser tube 4 through a pipe. The heating mechanism 2 is a far-infrared ceramic heating plate with a heat insulation layer 13 covering its surface. The spiral condenser tube 4 is made of a high thermal conductivity metal material, and the spiral diameter and tube length form a spiral heat exchange structure. The connecting pipe 8 is a Y-shaped structure, which is connected to the top of the distillation kettle 1 and the middle of the spiral condenser tube 4 respectively. An anti-backflow protection valve 14 is installed at the connection. The cooling jacket 12 is a double-layer spiral structure. The cooling water inlet is located at the bottom of the spiral condenser tube 4, and the outlet is located at the top. A liquid level sensor 15 is installed at the bottom of the collector 5. The liquid level sensor 15 is linked with the circulation pump 11. The system also includes an intelligent controller 16. The intelligent controller 16 adjusts the power of the heating mechanism 2 and the speed of the circulation pump 11 according to the feedback signals from the temperature sensor 6 and the liquid level sensor 15. The inner wall of the distillation kettle 1 is coated with a hydrophobic coating 17.

[0043] Working principle: When this new high-efficiency crude product distillation and condensation device is working, the crude product in the distillation vessel 1 is heated and vaporized by the far-infrared ceramic heating plate of the bottom heating mechanism 2, with a heat insulation layer 13 covering the surface. The steam enters the spiral condenser tube 4, made of high thermal conductivity metal, through the top steam outlet 3. The spiral structure increases the heat exchange area. At the same time, the vacuum pump 7, through the Y-type connecting pipe 8 with an anti-backflow protection valve 14, evacuates the air in the distillation vessel 1 to create a negative pressure environment to lower the boiling point of the liquid and improve the distillation efficiency. In the cooling water circulation system 9, the circulation pump 11 drives the cooling water in the cooling water tank 10 through the double-layer spiral cooling jacket 1 outside the spiral condenser tube 4. 2 Cooling water flows in from the bottom inlet and out from the top outlet, exchanging heat with the steam in the spiral condenser 4, causing the steam to condense into liquid and fall into the collector 5. The liquid level sensor 15 at the bottom of the collector 5 monitors the liquid level in real time and is linked with the circulating pump 11 to adjust the cooling water flow. The temperature sensor 6 at the steam outlet 3 monitors the steam temperature and feeds the signal back to the intelligent controller 16. The intelligent controller 16 automatically adjusts the power of the heating mechanism 2 and the speed of the circulating pump 11 through the PID algorithm to achieve dynamic optimization of the distillation process. The hydrophobic coating 17 on the inner wall of the distillation vessel 1 can reduce liquid adhesion and further improve the distillation efficiency.
