Description

Technical Field

[0001] This utility model relates to the technical field of distillation equipment, and in particular to an energy-saving condenser for distillation columns. Background Technology

[0002] Distillation columns are commonly used separation equipment in chemical production, separating different components from a mixture through heating and condensation. The condenser, a key component of the distillation column, is primarily used to condense gaseous substances into liquids. Located at the top of the distillation column, its main function is to condense vapor into liquid. A condenser typically consists of pipes through which a cooling medium flows. When high-temperature vapor enters the condenser, its heat is carried away through contact with the cooling medium, causing it to condense into a liquid.

[0003] However, existing condensers often have insufficient contact area between the heat exchange tubes containing steam and the cooling medium, resulting in slow condensation and significantly increasing condensation time, thus wasting energy. To address this issue, an energy-saving condenser for distillation columns is designed. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an energy-saving condenser for distillation columns. By installing two sets of serpentine heat exchange tubes inside the condenser shell, steam is diverted to the two sets of heat exchange tubes, greatly increasing the contact area between steam and the cooling medium and improving condensation efficiency. Furthermore, multiple sets of heat-conducting fins are arranged at intervals on the outer wall of the heat exchange tubes to further enhance the condensation effect and reduce energy waste in the condenser.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An energy-saving condenser for a distillation column includes a condenser shell, an upper head, and a lower head. The upper head is fixedly installed at the upper end of the condenser shell, and the lower head is provided at the lower end of the condenser shell. The condenser shell contains two sets of heat exchange tubes. One end of each heat exchange tube passes through the upper end of the condenser shell and extends out to connect to an inlet pipe via a connecting assembly. The other end of each heat exchange tube passes through the lower end of the condenser shell and communicates with a liquid collection tank. Multiple sets of heat-conducting fins are arranged at intervals on the outer wall of each heat exchange tube.

[0007] The connection assembly consists of a three-way diverter valve and a diverter pipe. One end of the three-way diverter valve is connected to the intake pipe, and the other two ports of the three-way diverter valve are respectively connected to the heat exchange pipes through the diverter pipes.

[0008] The air inlet pipe is located on the upper end cap, and the lower end cap is provided with a liquid outlet pipe. One end of the liquid outlet pipe is connected to the bottom of the liquid collection tank.

[0009] Specifically, multiple sets of supports are fixedly installed on the inner wall of the condenser shell. The supports are connected to the heat exchange tubes to reinforce the stability of the heat exchange tube installation.

[0010] Specifically, the heat exchange tubes are arranged in a serpentine, looping structure, which greatly increases the contact area between the heat exchange tubes and the cooling medium, thereby improving condensation efficiency.

[0011] Furthermore, a cooling medium inlet pipe is provided on one side of the lower end of the condenser shell, and a flow regulating valve is provided on the cooling medium inlet pipe.

[0012] Furthermore, a cooling medium outlet pipe is provided on one side of the upper end of the condenser shell.

[0013] Furthermore, temperature sensors are installed inside the cooling medium inlet pipe and the cooling medium outlet pipe to monitor the temperature changes of the cooling medium in real time.

[0014] The beneficial effects of this utility model are:

[0015] This invention installs two sets of serpentine heat exchange tubes inside the condenser shell. One end of each heat exchange tube is connected to the inlet pipe via a diverter pipe and a three-way diverter valve, thereby diverting steam into the two sets of heat exchange tubes. This greatly increases the contact area between the steam and the cooling medium, improving condensation efficiency. Furthermore, multiple sets of heat-conducting fins are arranged at intervals on the outer wall of the heat exchange tubes. These fins can better transfer heat from the heat exchange tubes to the cooling medium, further enhancing the condensation effect and reducing energy waste in the condenser.

[0016] This invention incorporates temperature sensors in the cooling medium inlet pipe and cooling medium outlet pipe to monitor the temperature changes of the cooling medium in real time. Furthermore, the flow rate of the cooling medium can be adjusted by operating the flow regulating valve, thereby achieving energy-saving effects. Attached Figure Description

A flow regulating valve 511 is provided on the cooling medium inlet pipe 51, and the flow rate of the cooling medium is adjusted by the flow regulating valve 511.

[0025] like Figure 2 Two sets of heat exchange tubes 7 are installed inside the condenser shell 1. The upper ends of the two sets of heat exchange tubes 7 pass through the upper end of the condenser shell 1 and extend out to connect with the inlet pipe 41 through the diverter pipe 62 and the three-way diverter valve 61. The lower ends of the heat exchange tubes 7 pass through the lower end of the condenser shell 1 and communicate with the liquid collection tank 9 located in the lower end cap 3. Multiple sets of heat-conducting fins 8 are arranged at intervals on the outer walls of the two sets of heat exchange tubes 7.

[0026] The three-way diverter valve 61 and the diverter pipe 62 are located inside the upper end cap 2.

It should be noted that the three-way diverter valve 61 uses existing components and can divert gas.

[0027] Specifically, the heat exchange tube 7 is arranged in a serpentine, looping structure, which greatly increases the contact area between the heat exchange tube 7 and the cooling medium, thereby improving the condensation efficiency.

[0030] Before using this utility model, it is necessary to install matching controllers on the temperature sensor and flow regulating valve in this utility model, and to connect the inlet pipe in this utility model to the outlet end of the distillation column. During use, the steam discharged from the distillation column enters through the inlet pipe 41, and is diverted to two sets of serpentine heat exchange tubes 7 through the three-way diverter valve 61 and the diverter pipe 62. The cooling medium is transported into the condenser shell 1 through the cooling medium inlet pipe 51, which greatly increases the contact area between the steam and the cooling medium in the heat exchange tube 7, improves the condensation efficiency, and multiple sets of heat-conducting fins 8 are arranged at intervals on the outer wall of the heat exchange tube 7. The heat-conducting fins 8 can better transfer the heat in the heat exchange tube 7 to the cooling medium, further enhancing the condensation effect and reducing the energy waste of the condenser.
