Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, and in particular to an evaporator with high efficiency gas-liquid separation. Background Technology

[0002] In traditional evaporators, the material mixture typically enters the system through a central circulation pipe, where it is heated within heat exchange tubes. This causes the volatile components to rise and separate, while the remaining liquid or solid material is discharged from the bottom. While this design achieves basic gas-liquid separation, it presents the following problems in practical applications: (a) Insufficient evaporation efficiency: Traditional evaporators rely on a single heating zone for gasification and separation. During the material's ascent, insufficient heat transfer may result in some volatile components failing to evaporate completely, thus reducing the separation efficiency.

[0003] (ii) Limited separation purity: Due to the large differences in physical properties between the gas, liquid and solid phases, traditional evaporators usually cannot achieve efficient three-phase separation, resulting in liquid droplets or solid particles being entrained in the gas, and unseparated components may also remain in the liquid or solid products. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an evaporator with high efficiency gas-liquid separation to solve one or more problems in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An efficient gas-liquid separation evaporator includes a first cylinder and a first end cap connected to the bottom of the first cylinder. The evaporator also includes a second end cap, which covers part of the first end cap and forms a first cavity with the first end cap. A first steam inlet is also provided on the surface of the second end cap, which opens into the first cavity.

[0006] Furthermore, a second cylinder is connected to the top of the first cylinder, and both the first end cap and the second cylinder are provided with flange rings near the first cylinder. The first cylinder is provided with tube sheets that cooperate with the flange rings near both the first end cap and the second cylinder.

[0007] Furthermore, a central circulation pipe is provided inside the first cylinder, with both ends of the central circulation pipe connected to and passing through the tube sheet. The central circulation pipe, the first cylinder, and the tube sheet also form a second cavity.

[0008] Furthermore, heat exchange tubes connected to the tube sheet are uniformly arranged in the second cavity, and a conduit connected to and penetrating the tube sheet is also included.

[0009] Furthermore, a second steam inlet, an exhaust port, and a first condensate outlet are provided on the surface of the first cylinder, which open into the second cavity; an ear seat is also connected to the outside of the first cylinder.

[0010] Furthermore, the evaporator also includes a third cylinder, which is disposed on the upper part of the second cylinder and communicates with the second cylinder; a fourth cylinder covering the third cylinder is also disposed on the upper part of the second cylinder, and a third end cap is connected to one end of the fourth cylinder.

[0011] Furthermore, a fifth cylinder located between the third cylinder and the fourth cylinder is also connected to the third end cap.

[0012] Furthermore, a return pipe is provided on the surface of the second cylinder between the third cylinder and the fourth cylinder, and a steam outlet is provided on the surface of the fourth cylinder.

[0013] Furthermore, the second cylinder is provided with a baffle near the bottom of the third cylinder; a vacuum gauge port, a manhole, a material inlet, a sight glass, and a first thermometer port are also provided on the surface of the second cylinder.

[0014] Furthermore, the bottom of the first end cap is provided with a material outlet; the surface of the second end cap is also provided with a second thermometer port that acts inside the first end cap, and the surface of the second end cap is also provided with a second condensate outlet that flows into the first cavity.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This embodiment of the high-efficiency gas-liquid separator evaporator employs a first-cavity secondary heating design. Specifically, a first cavity is formed by a first and a second end cap, and a first steam inlet is located within this first cavity. This solves the problem of insufficient efficiency in traditional single-stage heating, allowing insufficiently separated materials to receive supplemental heat energy for further separation. Furthermore, through the synergistic effect of a multi-layered nested separation structure—namely, the third cylinder, the fourth cylinder, the baffle, the fifth cylinder, and the return pipe—high-precision, multiple-stage heating and separation of materials is achieved, enabling continuous and efficient production.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a high-efficiency gas-liquid separation evaporator proposed by this utility model, in conjunction with the accompanying drawings and specific embodiments, will provide further clarity. The advantages and features of this utility model will become clearer from the following description. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, used only to facilitate and clearly illustrate the purpose of the embodiments of this utility model. Please refer to the accompanying drawings to make the objectives, features, and advantages of this utility model more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only used to complement the content disclosed in the specification, for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model.

[0020] Please see Figure 1 and Figure 2 The high-efficiency gas-liquid separation evaporator of this embodiment includes a first cylinder 1 and a first end cap 2 connected to the bottom of the first cylinder 1. The evaporator also includes a second end cap 3, which covers part of the first end cap 2 and forms a first cavity 4 with the first end cap 2. A first steam inlet 301 is also provided on the surface of the second end cap 3, which leads to the first cavity 4. Heating steam is introduced into the first cavity 4 through the first steam inlet 301 to reheat the material that has not been fully separated in the first end cap 2, thereby improving the separation efficiency of the material.

[0021] A material outlet 201 is also provided at the bottom of the first end cap 2. The remaining material after multiple separations is discharged through the material outlet 201. A second thermometer port 302 is also provided on the surface of the second end cap 3, which acts on the inside of the first end cap 2. The second thermometer port 302 is used to monitor the temperature change of the material inside the first end cap 2 in real time, so as to accurately control the amount of heating steam introduced. A second condensate outlet 303 is also provided on the surface of the second end cap 3, which leads to the first cavity 4. The second condensate outlet 303 is used to discharge the condensate formed after the heating steam in the first cavity 4 in a timely manner, so as to avoid the accumulation of condensate and affect the heating efficiency.

[0022] Furthermore, a second cylinder 5 is connected to the top of the first cylinder 1. Both the first end cap 2 and the second cylinder 5 are provided with flange rings 6 near the first cylinder 1. Tube sheets 7, which mate with the flange rings 6, are provided on the first cylinder 1 near both the first end cap 2 and the second cylinder 5. The flange rings 6 and the tube sheets 7 enable detachable connections between the first cylinder 1 and the first end cap 2 and the second cylinder 5, respectively, facilitating equipment installation, disassembly, and subsequent maintenance. Preferably, a sealing gasket can be provided between the flange ring 6 and the tube sheet 7 to enhance the sealing at the connection, prevent leakage during evaporator operation, and ensure stable operation.

[0023] Furthermore, a central circulation pipe 8 is provided inside the first cylindrical body 1, with both ends of the central circulation pipe 8 connected to and penetrating the tube sheet 7. The central circulation pipe 8, the first cylindrical body 1, and the tube sheet 7 also form a second cavity 9. Heat exchange tubes 901 connected to the tube sheet 7 are evenly arranged within the second cavity 9, and a conduit 902 connected to and penetrating the tube sheet 7 is also included. A second steam inlet 101, an exhaust port 102, and a first condensate outlet 103, all opening into the second cavity 9, are also provided on the surface of the first cylindrical body 1. The second steam inlet 101 is used to introduce heating steam into the second cavity 9 to heat the material flowing through the central circulation pipe 8, and simultaneously exchange heat with the liquid in the heat exchange pipe 901. The exhaust port 102 can promptly discharge non-condensable gases generated during the heat exchange process, preventing them from accumulating in the second cavity 9 and affecting the heat transfer effect. The first condensate outlet 103 is used to discharge the condensate formed by the steam condensation in the heat exchange pipe 901 and the second cavity 9, ensuring the continuous circulation of the heating medium. The gas-liquid mixture generated in the preliminarily separated material after heating flows upward through the conduit 902 into the second cylinder 5, and is discharged to the subsequent gas-liquid separation stage. An ear seat 104 is also connected to the outside of the first cylinder 1. The ear seat 104 is located on the outside of the first cylinder 1 and is used to stably support the entire evaporator structure on the mounting foundation.

[0024] Furthermore, the evaporator also includes a third cylinder 10, which is disposed on the upper part of the second cylinder 5 and communicates with the second cylinder 5. A fourth cylinder 11, covering the third cylinder 10, is also disposed on the upper part of the second cylinder 5, and a third end cap 12 is connected to one end of the fourth cylinder 11. A fifth cylinder 13, located between the third cylinder 10 and the fourth cylinder 11, is also connected to the third end cap 12. The arrangement of the third cylinder 10, the fourth cylinder 11, the fifth cylinder 13, and the third end cap 12 forms a multi-layered nested gas-liquid separation space, further capturing droplets entrained in the gas-liquid mixture introduced into the second cylinder 5 via the conduit 902, thus improving separation accuracy. A return pipe 14, communicating with the second cylinder 5, is also disposed between the third cylinder 10 and the fourth cylinder 11 on the surface of the second cylinder 5. A steam outlet 1101 is also disposed on the surface of the fourth cylinder 11.

[0025] The return pipe 14 can promptly guide the residual liquid separated between the third cylinder 10 and the fourth cylinder 11 back into the second cylinder 5, so that it can be heated again through the central circulation pipe 8 to achieve circulation separation and improve the separation effect. The steam outlet 1101 is used to export the pure steam obtained after multi-layer separation, so that the steam can be further processed or utilized in subsequent processes.

[0026] Furthermore, the second cylinder 5 is also provided with a baffle 15 near the bottom of the third cylinder 10. A vacuum gauge port 501, a manhole 502, a material inlet 503, a sight glass 504, and a first thermometer port 505 are also respectively provided on the surface of the second cylinder 5. The baffle 15 can separate the gas-liquid mixture flowing from the second cylinder 5 into the third cylinder 10. By changing the flow direction and speed of the gas-liquid mixture, the denser liquid is caused to impact the surface of the baffle 15 under inertia, thus further separating it from the gas. The separated liquid slides down the baffle 15 and continues to flow through the central circulation pipe 8 for further circulation and separation. The vacuum gauge port 501 is used to connect a vacuum gauge to monitor the vacuum level inside the second cylinder 5 in real time, ensuring that the evaporator operates under the set vacuum conditions to improve evaporation efficiency. The manhole 502 facilitates personnel to enter the second cylinder 5 for inspection, cleaning, and other maintenance work. The material inlet 503 is the channel through which the gas-liquid mixture to be processed enters the equipment. By adding material into the central circulation pipe 8, it provides raw materials for the evaporation and separation process. The sight glass 504 allows operators to visually observe the liquid level, boiling state, and other conditions of the material inside the second cylinder 5, enabling timely adjustments to operating parameters. The first thermometer port 505 is used to install a thermometer to monitor the temperature of the material inside the second cylinder 5, providing temperature data support for process control.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
