Description

Technical Field

[0001] This utility model relates to the field of liquefied petroleum gas technology, specifically to a steam-type high-efficiency LPG vaporizer. Background Technology

[0002] Liquefied petroleum gas (LPG) is a highly efficient and clean energy source widely used in industrial, commercial, and residential sectors. LPG is typically stored and transported in liquid form, but it needs to be converted into a gaseous state for use, thus requiring a gasification device.

[0003] Existing vaporizers have many shortcomings in terms of structural design and heat exchange mechanism. For example, the arrangement and distribution of heat exchange tube bundles lack scientific design, resulting in the heat transfer area and liquid separation function failing to meet process requirements. At the same time, the local temperature gradient is too large, which leads to frequent liquid entrainment in the LPG vaporization process, resulting in low vaporization efficiency and high energy consumption.

[0004] Therefore, it is necessary to design an efficient, energy-saving LPG gasification device that can effectively prevent liquid entrainment in order to improve gasification efficiency, reduce energy consumption, and ensure stable gas supply. Summary of the Invention

[0005] The technical implementation scheme of this utility model is as follows: A steam-type high-efficiency LPG vaporizer includes a mounting frame, a housing, a steam heater, a vaporization box, a steam input pipe, a vaporization cylinder, a spiral guide plate, a liquid liquefied gas input pipe, and a gaseous liquefied gas output pipe. The housing and the steam heater are mounted side by side on the mounting frame. The vaporization box is set in the inner cavity of the housing. A steam input pipe connects the steam heater and the inner cavity of the vaporization box. The vaporization cylinder is installed in the vaporization box. There is a cavity between the vaporization cylinder and the vaporization box. When the steam heater is working, the steam generated is input into the cavity between the vaporization cylinder and the vaporization box through the steam input pipe to heat the vaporization cylinder. The lower end of the vaporization cylinder is connected to the liquid liquefied gas input pipe, and the upper end is connected to the gaseous liquefied gas output pipe. A spiral guide plate is set in the vaporization cylinder. After the liquid liquefied gas is input into the vaporization cylinder through the steam input pipe, it moves to the upper part of the vaporization cylinder through the spiral guide plate.

[0006] More preferably, vaporization pipes are provided at intervals on the outer wall of the vaporization cylinder, and the vaporization pipes are located in the cavity between the vaporization box and the vaporization cylinder.

[0007] More preferably, the density of the vaporization tubes gradually decreases from bottom to top.

[0009] More preferably, the steam heater is equipped with a pressure regulator that controls the amount of steam output from the steam input pipe, and the pressure regulator is electrically connected to a human-machine interface controller installed on the housing.

[0010] More preferably, a flow rate detector is installed on the liquefied gas inlet pipe to monitor the flow rate of the liquid inside.

[0011] More preferably, a temperature monitor is installed at the outlet of the gaseous liquefied gas output pipe, and the temperature monitor is electrically connected to a human-machine interface controller installed on the enclosure.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The residence time of liquid LPG in the gasification cylinder is extended by the spiral guide plate, ensuring full heat absorption and gasification, and avoiding liquid phase entrainment.

[0013] 2. The design of the vaporization tube with gradually decreasing density from bottom to top matches the volume expansion characteristics during LPG vaporization, optimizes heat transfer efficiency, reduces local temperature gradients, and further improves vaporization uniformity.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example: A steam-type high-efficiency LPG vaporizer, such as Figures 1-4 As shown, the system includes a mounting frame 1, a housing 2, a steam heater 3, a vaporization box 4, a steam input pipe 41, a vaporization cylinder 6, a spiral guide plate 9, a liquid liquefied gas input pipe 10, and a gaseous liquefied gas output pipe 12. The housing 2 and the steam heater 3 are mounted side-by-side on the mounting frame 1. The vaporization box 4 is located inside the housing 2. A steam input pipe 41 connects the steam heater 3 and the inner cavity of the vaporization box 4. The vaporization cylinder 6 is installed inside the vaporization box 4, and a cavity exists between the vaporization cylinder 6 and the vaporization box 4. Steam generated by the steam heater 3 during operation is passed through the steam... The input pipe 41 enters the cavity between the vaporization cylinder 6 and the vaporization box 4 to heat the vaporization cylinder 6. The cavity between the vaporization cylinder 6 and the vaporization box 4 forms a uniform heat exchange environment. The lower end of the vaporization cylinder 6 is connected to the liquid liquefied gas input pipe 10, and the upper end is connected to the gaseous liquefied gas output pipe 12. A spiral guide plate 9 is provided inside the vaporization cylinder 6. After the liquid liquefied gas input pipe 10 enters the vaporization cylinder 6, it moves to the upper part of the vaporization cylinder 6 through the spiral guide plate 9. The spiral guide plate 9 can prolong the residence time of LPG in the cylinder, thereby ensuring that the liquid LPG fully absorbs heat and vaporizes.

[0022] like Figure 2 and Figure 3 As shown, vaporization tubes 42 are spaced apart on the outer wall of the vaporization cylinder 6. The vaporization tubes 42 are located in the cavity between the vaporization box 4 and the vaporization cylinder 6. The arrangement of the vaporization tubes 42 allows the steam heat to further expand the contact area and improve the heat transfer efficiency. Moreover, the density of the vaporization tubes 42 gradually decreases from bottom to top. This arrangement allows the lower part of the vaporization cylinder 6 to receive more heat to achieve rapid vaporization of the liquid LPG in the vaporization cylinder 6. Since most of the LPG in the upper part of the vaporization cylinder 6 has already vaporized, the required heat exchange is relatively small. The density design of the vaporization tubes 42 can avoid local overheating of the vaporization cylinder 6.

[0023] like Figure 4 As shown, a rotating roller 8 is rotatably arranged inside the gasification cylinder 6, and a spiral guide plate 9 is arranged along the axial direction of the rotating roller 8 and is located on the outer wall of the rotating roller 8. A motor 7 is installed at the bottom of the inner side of the housing 2. The output shaft of the motor 7 is connected to the rotating roller 8. The rotating roller 8 is driven to rotate by the motor 7, and the liquid LPG is conveyed to the upper part of the gasification cylinder 6 through the spiral guide plate 9, and the liquid LPG is gasified during the conveying process.

[0024] In use, the steam heater 3 generates high-temperature steam after starting. The high-temperature steam enters the cavity between the vaporization box 4 and the vaporization cylinder 6 through the steam input pipe 41, thereby forming a heat exchange environment. Liquid LPG enters from the lower end of the vaporization cylinder 6 through the liquid liquefied gas input pipe 10. The rotating roller 8 inside the vaporization cylinder 6 rotates under the drive of the motor 7, thereby driving the spiral guide plate 9 to push the liquid LPG spirally upward along the inner wall of the cylinder. During the spiral ascent, the liquid LPG continuously contacts the inner wall of the vaporization cylinder 6 heated by steam, absorbs heat and gradually vaporizes. The vaporized LPG gas gathers at the upper part of the vaporization cylinder 6 and is discharged through the gaseous liquefied gas output pipe 12.

[0025] like Figure 2 As shown, the steam heater 3 is equipped with a pressure regulator 5 that controls the amount of steam output from the steam input pipe 41. The pressure regulator 5 is electrically connected to the human-machine interface controller 14 installed on the housing 2. The pressure regulator 5 adjusts the amount of steam output according to the instructions of the human-machine interface controller 14 to ensure stable heating temperature.

[0026] like Figure 4 As shown, a flow rate detector 11 is installed on the liquid liquefied gas input pipe 10 to monitor the internal liquid flow rate. The flow rate detector 11 monitors the liquid LPG flow rate in real time and feeds it back to the human-machine interface controller 14.

[0027] like Figure 4 As shown, a temperature monitor 13 is installed at the outlet of the gaseous liquefied gas output pipe 12. The temperature monitor 13 is electrically connected to the human-machine interface controller 14 installed on the housing 2. The temperature monitor 13 detects the air temperature at the outlet of the gaseous liquefied gas output pipe 12 in real time and feeds it back to the human-machine interface controller 14. The human-machine interface controller 14 controls the outlet temperature of the gaseous liquefied gas output pipe 12 to be stably maintained at 80-85℃, thereby ensuring that the LPG passing through the outlet is completely vaporized.

[0028] Temperature monitor 13 monitors the temperature at the outlet of gaseous liquefied gas output pipe 12 in real time and transmits the monitoring data to human-machine interface controller 14. When the temperature at the outlet of gaseous liquefied gas output pipe 12 is detected to be lower than 80 degrees, human-machine interface controller 14 increases the output pressure of steam input pipe 41 by controlling pressure regulator 5, thereby increasing the steam input. When the temperature at the outlet of gaseous liquefied gas output pipe 12 is detected to be higher than 85 degrees, human-machine interface controller 14 decreases the output pressure of steam input pipe 41 by controlling pressure regulator 5, thereby reducing the steam input, thus ensuring that the liquefied gas output from gaseous liquefied gas output pipe 12 is gaseous.

Therefore, the scope of this disclosure should not be limited to the above embodiments, but should be defined not only by the appended claims, but also by their equivalents.
