Description

Technical Field

[0001] This invention relates to the field of distillation technology, specifically to a distillation apparatus and method for improving yield and separation efficiency. Background Technology

[0002] Distillation is a separation process that utilizes the different volatility of components in a mixture to separate them. Commonly used equipment includes plate distillation columns and packed distillation columns. The principle and equipment process of precision distillation are the same as those of ordinary distillation, except that the relative volatility of the components in the system to be separated is relatively small (<1.05~1.10), so high-efficiency precision packing is used to achieve the separation and purification of the components.

[0003] In existing distillation columns, the trays do not allow for sufficient contact between hot gas and reflux liquid due to insufficient dispersion of the hot gas, which affects the yield and separation effect of the material. In addition, existing trays may also have leakage problems, which affects the distillation operation and makes them inconvenient for users.

[0004] To address the aforementioned problems, an improved distillation apparatus and method are designed to enhance yield and separation efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a distillation apparatus and method that improves yield and separation efficiency, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A distillation apparatus for improving yield and separation efficiency includes a column body. Support legs are installed at the lower end of the column body. A liquid inlet pipe and a gas inlet pipe are installed at the lower end of the column body's side wall. A liquid outlet pipe is installed at the lower end of the column body, and a gas outlet pipe is installed at the upper end of the column body. A reflux pipe is provided at the upper end of the column body's side wall. The external connections of the liquid inlet pipe, liquid outlet pipe, gas inlet pipe, reflux pipe, and gas outlet pipe are the same as in the prior art and will not be specifically described. A flow guiding mechanism for guiding the reflux liquid is provided inside the column body between the reflux pipe and the liquid inlet pipe and the gas inlet pipe. A heating mechanism for heating the reflux liquid with hot gas is provided on the flow guiding mechanism.

[0008] As a further aspect of the present invention: the flow guiding mechanism includes several dividing components, which are horizontally arranged inside the tower body between the return pipe and the liquid inlet pipe and the air inlet pipe. The output ends of two adjacent dividing components are opposite, so that the water flow is S-shaped. The dividing components include several fixed frames, and a flow guide plate is arranged between two adjacent fixed frames. The flow guide plate is installed on the lower end of the side wall of the fixed frame. The side walls of the fixed frames and the flow guide plate near the inner wall of the tower body are both installed on the inner wall of the tower body. A flow guide pipe is vertically installed at the output end of the flow guide plate. The lower end of the flow guide pipe is located at the upper end of the flow guide plate directly below. A flow dividing component for dividing the return liquid is provided at the upper end of the tower body.

[0009] As a further embodiment of the present invention, the guide plate and the fixing frame are integrally processed.

[0010] As a further embodiment of the present invention: the diversion assembly includes a controller, a diversion pipe is vertically arranged at the output end of the guide plate near the top of the tower body, the end of the diversion pipe away from the guide plate passes through the side wall of the tower body and is installed with a main pipe, the output end of the return pipe is installed on the main pipe, and a flow control valve for controlling the flow of the diversion pipe is installed on the side wall of the diversion pipe outside the tower body, and the controller is installed on the side wall of the tower body.

[0011] As a further embodiment of the present invention: the heating mechanism includes several floats, which are evenly arranged inside the guide plate. A flexible tube is installed at the lower end of each float. Several vent holes are opened on the side wall of the flexible tube to allow hot air to be blown into the return liquid. A U-shaped connecting pipe is installed at the upper end of the flexible tube. A sliding tube is installed at the end of the U-shaped connecting pipe away from the flexible tube. Several through holes corresponding to the sliding tubes are opened at the upper end of the fixed frame near the guide plate. The sliding tubes are slidably and sealed to the inner wall of the through holes. A pressurizing component for maintaining the pressure of hot air flow is provided between two adjacent partition components.

[0012] As a further embodiment of the present invention: the pressurization component includes a plurality of partitions, the partitions are horizontally installed on the inner wall of the tower body between two adjacent partition components, a blower is installed on the partition for blowing the air below the partition upward, and a gas pressure detection sensor is installed on the inner wall of the tower body between two adjacent partition components.

[0013] As a further embodiment of the present invention: a receiving frame for receiving foreign objects is provided directly below the blower, and a plurality of connecting columns are installed on the upper end of the receiving frame, the upper ends of the connecting columns being installed on the lower end of the partition.

[0014] As a further aspect of the present invention: a number of reinforcing support ribs for improving the structural strength of the tower are installed on the side wall of the tower body.

[0015] As a further embodiment of the present invention: a collection frame is installed at both the top and bottom of the tower body.

[0016] A method of using a distillation apparatus to improve yield and separation efficiency includes the following steps:

[0017] Step 1: During use, the reflux liquid is sequentially transported to the main pipe and branch pipes through the reflux pipe. The flow rate of each branch pipe is controlled in real time by the flow control valve and controller to ensure that the flow rate of each branch pipe is the same. The branch pipe transports the reflux liquid to the guide plate, and the guide plate transports the reflux liquid to the guide pipe. Under the action of several guide plates and guide pipes, the reflux liquid flows in an S-shape and finally flows to the bottom of the tower.

[0018] Step 2: Due to buoyancy, the float floats on the top of the reflux liquid. The float pulls the hose, which in turn moves the U-shaped connecting tube. The U-shaped connecting tube then moves the sliding tube along the inner wall of the perforation.

[0019] Meanwhile, hot air is transported into the tower body through the air inlet pipe. Under pressure, the hot air passes through the slide pipe, U-shaped connecting pipe, hose, and exhaust hole in sequence, so that the hot air heats and evaporates the reflux liquid.

[0020] Step 3: The gas pressure sensor detects the pressure above and below the baffle in real time and transmits the data to the controller for analysis. When the pressure difference between the baffle and the baffle is small, the blower is started. The blower delivers the air below the baffle to the baffle above the baffle, thereby changing the pressure difference between the baffle and the baffle.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention controls the flow rate of the distribution pipes by using a flow control valve to ensure that the flow rate of each distribution pipe is the same. Then, the reflux liquid output from the distribution pipes is transported to the guide plate, thereby distributing the reflux liquid evenly, ensuring the flow rate of the reflux liquid, and thus ensuring the processing capacity of the distillation.

[0023] Meanwhile, by setting several hoses on the guide plate, hot gas can be transported to the reflux liquid on the guide plate through the hoses, which can fully enable the hot gas to come into contact with the reflux liquid and improve the distillation efficiency of the reflux liquid.

[0024] This invention, by setting a float at the upper end of the hose and a U-shaped connecting pipe at the upper end of the float, can effectively prevent the reflux liquid from leaking through the U-shaped connecting pipe, and can adjust the reflux liquid depth in real time, thereby effectively improving the distillation efficiency of the reflux liquid.

[0025] This invention uses a gas pressure sensor to detect the pressure above and below the guide plate in real time, and uses a blower to pressurize it, ensuring the efficient flow of hot air in the slide pipe, U-shaped connecting pipe, hose, and exhaust port when near the top of the tower, making it convenient for users.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-5In this embodiment of the invention, a distillation apparatus for improving yield and separation effect includes a column body 1. A support leg 3 is installed at the lower end of the column body 1 to support it. A liquid inlet pipe 2 and an air inlet pipe 5 are installed at the lower end of the side wall of the column body 1.

A flow guiding mechanism for guiding the reflux liquid is provided inside the column body 1 between the reflux pipe 8 and the liquid inlet pipe 2 and air inlet pipe 5. A heating mechanism for heating the reflux liquid with hot gas is provided on the flow guiding mechanism.

[0034] The flow guiding mechanism includes several dividing components, which are horizontally arranged inside the tower body 1 between the return pipe 8, the liquid inlet pipe 2, and the air inlet pipe 5. The output ends of two adjacent dividing components are opposite, causing the water flow to be S-shaped. Each dividing component includes several fixed frames 14, and a flow guide plate 15 is arranged between two adjacent fixed frames 14. The flow guide plate 15 is installed on the lower end of the side wall of the fixed frame 14. The side walls of the fixed frames 14 and the flow guide plate 15 near the inner wall of the tower body 1 are both installed on the inner wall of the tower body 1. A flow guide pipe 11 is vertically installed at the output end of the flow guide plate 15. The lower end of the flow guide pipe 11 is located on the upper end of the flow guide plate 15 directly below. A flow diversion component for diverting the return liquid is provided at the upper end of the tower body 1.

[0035] The diversion assembly includes a controller 7. A diversion pipe 17 is vertically installed at the output end of the guide plate 15 near the top of the tower body 1. The end of the diversion pipe 17 away from the guide plate 15 passes through the side wall of the tower body 1 and is connected to a main pipe 19. The output end of the return pipe 8 is installed on the main pipe 19. Flow control valves 18 for controlling the flow of the diversion pipe 17 are installed on the side wall of the diversion pipe 17 outside the tower body 1. The controller 7 is installed on the side wall of the tower body 1.

[0036] In use, the reflux liquid is sequentially transported to the main pipe 19 and the branch pipe 17 through the reflux pipe 8. The flow rate of each branch pipe 17 is controlled in real time by the flow control valve 18 and the controller 7 to ensure that the flow rate of each branch pipe 17 is the same. The branch pipe 17 transports the reflux liquid to the guide plate 15, and the guide plate 15 transports the reflux liquid to the guide pipe 11. Under the action of several guide plates 15 and guide pipes 11, the reflux liquid flows in an S-shape and finally flows to the bottom of the tower body 1.

[0037] The heating mechanism includes several floats 20, which are evenly arranged inside the guide plate 15. A flexible hose 23 is installed at the lower end of each float 20. Several exhaust holes 24 are opened on the side wall of the flexible hose 23 to allow hot air to be blown into the return liquid. A U-shaped connecting pipe 16 is installed at the upper end of the flexible hose 23. A sliding pipe 22 is installed at the end of the U-shaped connecting pipe 16 away from the flexible hose 23. Several through holes 21 corresponding to the sliding pipe 22 are opened at the upper end of the fixing frame 14 near the guide plate 15. The sliding pipe 22 is slidably and sealed to the inner wall of the through hole 21. A pressurizing component is provided between two adjacent partition components to maintain the pressure of hot air flow.

[0038] During use, due to buoyancy, float 20 floats on the top of the reflux liquid. Float 20 pulls hose 23, which in turn moves U-shaped connecting pipe 16. U-shaped connecting pipe 16 then moves slide tube 22 along the inner wall of perforation 21.

[0039] Meanwhile, hot air is transported into the tower body 1 through the air inlet pipe 5. Under pressure, the hot air passes through the slide pipe 22, U-shaped connecting pipe 16, hose 23 and exhaust hole 24 in sequence, so that the hot air heats and evaporates the reflux liquid.

[0040] The pressurization assembly includes several partitions 13, which are horizontally installed on the inner wall of the tower body 1 between two adjacent partitions. A blower 12 is installed on the partition 13 to blow the air below the partition 13 upward. A gas pressure detection sensor 6 is installed on the inner wall of the tower body 1 between two adjacent partitions.

[0041] A receiving frame 25 for receiving foreign objects is provided directly below the blower 12. Several connecting posts 26 are installed on the upper end of the receiving frame 25, and the upper ends of the connecting posts 26 are installed on the lower end of the partition 13.

[0042] During use, the gas pressure sensor 6 detects the pressure above and below the baffle 15 in real time and transmits the detection data to the controller 7 for analysis. When the pressure difference between the baffle 15 and the baffle 15 is small, the blower 12 is started. The blower 12 delivers the air below the baffle 13 to the baffle 13 above the baffle 13, thereby changing the pressure difference between the baffle 15 and the baffle 15.

[0043] The working principle of a distillation apparatus for improving yield and separation efficiency:

[0044] In use, the reflux liquid is sequentially transported to the main pipe 19 and the branch pipe 17 through the reflux pipe 8. The flow rate of each branch pipe 17 is controlled in real time by the flow control valve 18 and the controller 7 to ensure that the flow rate of each branch pipe 17 is the same. The branch pipe 17 transports the reflux liquid to the guide plate 15, and the guide plate 15 transports the reflux liquid to the guide pipe 11. Under the action of several guide plates 15 and guide pipes 11, the reflux liquid flows in an S-shape and finally flows to the bottom of the tower body 1.

[0045] During use, due to buoyancy, float 20 floats on the top of the reflux liquid. Float 20 pulls hose 23, which in turn moves U-shaped connecting pipe 16. U-shaped connecting pipe 16 then moves slide tube 22 along the inner wall of perforation 21.

[0046] Meanwhile, hot air is transported into the tower body 1 through the air inlet pipe 5. Under pressure, the hot air passes through the slide pipe 22, U-shaped connecting pipe 16, hose 23 and exhaust hole 24 in sequence, so that the hot air heats and evaporates the reflux liquid.

[0047] During use, the gas pressure sensor 6 detects the pressure above and below the baffle 15 in real time and transmits the detection data to the controller 7 for analysis. When the pressure difference between the baffle 15 and the baffle 15 is small, the blower 12 is started. The blower 12 delivers the air below the baffle 13 to the baffle 13 above the baffle 13, thereby changing the pressure difference between the baffle 15 and the baffle 15.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
