Description

Technical Field

[0001] This utility model belongs to the technical field of gas appliance performance testing, and specifically relates to a temperature-controlled gasification mixing device. Background Technology

[0002] When testing gas appliances, liquefied petroleum gas (LPG) must be provided to regulate the experimental conditions. Typically, LPG is a mixture of methane and butane in a 3:1 ratio, stored in a gas cylinder in liquid form. Before the experiment begins, the liquid LPG is introduced into a vaporizer, where it is converted into a gaseous state and then supplied to the gas appliances.

[0003] However, considering the density difference between methane and butane, they are prone to stratification in the storage tank. The applicant observed in experiments that inverting the storage tank or connecting a pipe to the bottom of the tank to drain the liquid could alleviate the stratification problem to some extent. However, when the liquefied gas enters the vaporizer, the incomplete mixing of methane and butane can lead to a significant deviation of the methane-to-butane ratio in the gas mixture supplied to the gas appliances from the preset value, thus affecting the accuracy of the experimental results.

[0004] On the other hand, ambient air vaporizers are commonly used in gas appliance testing. These vaporizers rely on ambient temperature to heat liquefied petroleum gas (LPG), converting it into a gaseous state. However, fluctuations in ambient temperature and the inherent heat exchange efficiency limitations of ambient air vaporizers often make it difficult to guarantee complete and stable vaporization of the LPG. Especially in low-temperature environments, the vaporization efficiency of ambient air vaporizers decreases significantly, leading to insufficient gas supply to the appliance or the presence of incompletely vaporized liquid components in the gas. This not only affects the normal operation of the gas appliance but may also negatively impact the accuracy of the test results. Summary of the Invention

[0005] This invention aims to provide a temperature-controlled vaporization mixing device to solve the problems of insufficient vaporization, uneven mixing, and significant susceptibility to ambient temperature in existing technologies for liquefied petroleum gas (LPG). By integrating a temperature control system with a mixing mechanism, this device ensures stable and sufficient heating of the LPG during vaporization, thereby achieving a uniform mixture of methane and butane. Furthermore, the introduction of the temperature control system eliminates the limitations imposed by ambient temperature fluctuations in the vaporization process, enabling it to maintain efficient and stable operation under various conditions.

[0006] To achieve the above objectives, this utility model provides a temperature-controlled vaporization mixing device, characterized in that: it includes a water bath, in which a liquid inlet chamber and a gas outlet chamber are provided, and a pipeline mechanism is connected between the liquid inlet chamber and the gas outlet chamber. The pipeline mechanism includes several parallel-arranged meandering pipelines, and each meandering pipeline is provided with a mixing structure.

[0007] Furthermore, the hybrid structure includes a spiral channel formed in the meandering conduit.

[0008] Furthermore, the spiral channel is segmented, and the inlets and outlets of adjacent spiral channels are staggered.

[0009] Furthermore, the multiple spiral channels are evenly distributed along the meandering path of the meandering pipeline.

[0010] Furthermore, a liquefied gas inlet communicating with the liquid inlet chamber and a liquefied gas outlet communicating with the gas outlet chamber are provided on the top of the water bath. A first pressure gauge, a plate flow meter and a first manual valve are connected in sequence to the liquefied gas inlet, and a second pressure gauge and a second manual valve are connected in sequence to the liquefied gas outlet.

[0011] Furthermore, a third pressure gauge and a water level gauge are also installed on the wall of the water bath.

[0012] Furthermore, the water bath is provided with a water inlet at the top and a water outlet at the bottom.

[0013] Furthermore, a circulating heater is installed near the water bath, and the inlet and outlet of the circulating heater are respectively connected to the tank space of the water bath.

[0014] Furthermore, the circulating heater is integrated into a mounting box on the side wall of the water bath.

[0015] Furthermore, a display controller for displaying and adjusting device parameters is also provided on the mounting box.

[0016] Compared with the prior art, the significant advantages of this utility model are:

[0017] (1) This utility model extends the vaporization path by arranging a pipeline mechanism in the water bath. The pipeline mechanism consists of a series of parallel and detour pipelines. It can not only make full use of the space of the tank and optimize the heat transfer process, but also ensure that the fluid can be in uniform and sufficient contact with the water, thereby achieving an efficient vaporization process. At the same time, the detour pipelines can also change the direction of the fluid to a certain extent, playing a role in assisting fluid mixing.

[0018] (2) Introducing a mixing structure into the meandering pipeline promotes the interaction and diffusion between methane and butane molecules by continuously changing the flow direction of the fluid, achieving a more uniform mixing effect. In addition, the mixing structure also extends the flow path of the fluid, which helps the fluid to vaporize more fully;

[0019] (3) The mixing structure adopts a spiral channel design, which makes the fluid rotate along the spiral path. This rotational motion not only prolongs the flow path of the gas, but also causes the gas to change direction frequently during the flow, thereby increasing the collision frequency between fluid molecules. These collisions help to disrupt the original structure between fluid molecules, thereby promoting the diffusion and mixing between methane and butane molecules;

[0020] (4) The spiral channel adopts a segmented structure design with staggered inlets and outlets, ensuring that the fluid undergoes a sharp change in direction when entering the next spiral segment and generates violent collisions at the inlet. This design helps to further disrupt the original structure between fluid molecules and promotes thorough mixing of methane and butane molecules. In addition, the segmented structure makes the fluid flow in the spiral channel more complex and variable, which is conducive to the formation of turbulence, increases the collision frequency between fluid molecules, and thus improves the mixing efficiency.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Figures 1 to 3 The first embodiment of the present invention is shown: a temperature-controlled vaporization mixing device, including a water bath 1, wherein the water bath 1 is provided with a liquid inlet chamber 2 and a gas outlet chamber 3, and a pipeline mechanism 4 is connected between the liquid inlet chamber 2 and the gas outlet chamber 3. The pipeline mechanism 4 includes a plurality of detour pipelines 401 arranged side by side, and each of the detour pipelines 401 is provided with a mixing structure 402.

[0033] like Figure 4 and Figure 5 As shown, in a specific implementation, the hybrid structure 402 includes a spiral channel 4021 formed in the meandering pipeline 401. The spiral channel 4021 is segmented, and the inlets and outlets of adjacent spiral channel segments 4021 are staggered. Multiple spiral channel segments 4021 are evenly distributed along the meandering path of the meandering pipeline 401. Figure 2Taking two adjacent spiral channels 4021 as an example, the correspondence between the outlet of the upper spiral channel 4021a and the inlet of the lower spiral channel 4021b can be seen from the figure.

[0034] Please see Figure 6 and Figure 7 In this embodiment, a liquefied gas inlet 5 communicating with the liquid inlet chamber 2 and a liquefied gas outlet 6 communicating with the gas outlet chamber 3 are provided on the top of the water bath 1. A first pressure gauge 7, a plate flow meter 8, and a first manual valve 9 are sequentially connected to the liquefied gas inlet 5, and a second pressure gauge 10 and a second manual valve 11 are sequentially connected to the liquefied gas outlet 6. A third pressure gauge 12 and a water level gauge 13 are also provided on the wall of the water bath 1. A water inlet 14 is provided on the top of the water bath 1, and a water outlet 15 is provided on the bottom of the water bath 1. A circulating heater 16 is provided near the water bath 1, and the inlet and outlet of the circulating heater 16 are respectively connected to the body space of the water bath 1. The circulating heater 16 is integrated into a mounting box 17 on the side wall of the water bath 1. A display controller 18 for displaying and adjusting device parameters is also provided on the mounting box 17.

[0035] In practical applications, liquefied petroleum gas (LPG) enters the system through LPG inlet 5, passes through the first pressure gauge 7, plate flow meter 8, and is precisely regulated by the first manual regulating valve, before flowing into the inlet chamber 2 within the water bath 1. Next, the LPG enters the meandering pipeline 401 through the piping system, where it flows. In the meandering pipeline 401, the LPG is guided along multiple spiral channels 4021, rotating forward along the spiral path. This rotational motion not only extends the flow path of the LPG but also causes it to frequently change direction, thereby increasing the collision frequency between LPG molecules and promoting the diffusion and mixing of methane and butane molecules. Furthermore, because the spiral channels 4021 adopt a segmented design, and the inlets and outlets of adjacent spiral channels 4021 are staggered, this allows for intense collisions and mixing of the LPG when entering the next spiral segment, further promoting the diffusion and uniform mixing of methane and butane molecules. Simultaneously, the segmented structure also makes the flow of fluid within the spiral channels 4021 more complex and variable, contributing to the formation of turbulence and further improving mixing efficiency.

[0036] The thoroughly mixed liquefied gas finally flows into the outlet chamber 3. In the outlet chamber 3, multiple streams of vaporized liquefied gas are fully mixed according to the principle of turbulent convergence. After being regulated by the second pressure gauge 10 and the second manual regulating valve, the mixture is discharged from the liquefied gas outlet 6 to supply gas appliance testing experiments. Throughout the process, the circulating heater 16 continuously heats the water in the water bath 1 to maintain a stable heating temperature. Simultaneously, the user can monitor and adjust the device's operating parameters, such as heating temperature and gas flow rate, in real time via the display controller 18 to ensure the device maintains a highly efficient and stable operating state under various conditions.

[0037] In addition, this utility model is equipped with a variety of safety protection measures. For example, a third pressure gauge 12 and a water level gauge 13 are installed on the wall of the water bath 1 to monitor the pressure and water level inside the water bath 1 in real time, ensuring that the device operates within a safe range. At the same time, the top of the water bath 1 is provided with a water inlet 14 and the bottom with a water outlet 15, which facilitates daily maintenance and upkeep by the user.

[0038] In summary, this invention extends the vaporization path by arranging a piping mechanism 4 within the water bath 1. This piping mechanism 4 consists of a series of parallel, meandering pipes 401. It not only fully utilizes the space within the bath and optimizes the heat transfer process, ensuring uniform and sufficient contact between the fluid and water for efficient vaporization, but also alters the fluid direction to some extent, aiding in fluid mixing. The introduction of a mixing structure 402 within the meandering pipes 401 continuously changes the fluid's flow direction, promoting interaction and diffusion between methane and butane molecules, resulting in a more uniform mixing effect. Furthermore, the mixing structure 402 extends the fluid's flow path, contributing to more complete vaporization. The mixing structure 402 employs a spiral channel 4021 design, causing the fluid to rotate along the spiral path. This rotational motion not only extends the gas's flow path but also causes frequent changes in gas direction during flow, thereby increasing the collision frequency between fluid molecules. These collisions help disrupt the original structure between fluid molecules, thereby promoting the diffusion and mixing of methane and butane molecules. The spiral channel 4021 employs a segmented structure with staggered inlets and outlets, ensuring that the fluid undergoes a sharp change of direction and generates vigorous collisions at the inlet when entering the next spiral segment. This design further disrupts the original structure between fluid molecules, promoting thorough mixing of methane and butane molecules. Furthermore, the segmented structure makes the fluid flow within the spiral channel 4021 more complex and variable, which is conducive to the formation of turbulence, increases the collision frequency between fluid molecules, and thus improves mixing efficiency.

[0039] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
