Description

Technical Field

[0001] This utility model relates to the technical field of light hydrocarbon gas generating equipment, specifically to a separation and circulation device and a gasification kettle. Background Technology

[0002] In the production of light hydrocarbon fuel, a gasification reactor is typically used to convert liquid light hydrocarbons into light hydrocarbon fuel.

[0003] CN216890828U discloses a light hydrocarbon gasification generator at ambient temperature and pressure. The raw liquid is simply transported to the inside of the gasification vessel through the exhaust port using an oil-gas separator. Since the hot water circulation pipe can work with the heating pipe on the gasification vessel to complete the hot water circulation, the light hydrocarbon solution in the gasification vessel is heated by the heating pipe. The light hydrocarbon fuel gas is separated by bubbling air into the light hydrocarbon solution, that is, by the buoyancy and surface tension of the air bubbles, which promotes the transfer of light hydrocarbon molecules from the liquid phase to the gas phase after heating.

[0004] However, this patent directly blows outside air into the light hydrocarbon solution through the air inlet pipe, which means that the blown-in air needs to absorb heat from the light hydrocarbon solution, which is not conducive to improving the light hydrocarbon separation efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a separation and circulation device and a gasification vessel to solve the technical problem in the prior art where external air is directly blown into the light hydrocarbon solution through the air inlet pipe, which causes the blown-in air to absorb heat from the light hydrocarbon solution, thus hindering the improvement of light hydrocarbon separation efficiency.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides a separation and circulation device, comprising:

[0008] A heating chamber, used to contain and heat heat exchange fluids;

[0009] A heat exchange structure is provided with an installation position and a heat exchange position, and has a heat exchange flow channel flowing through the installation position and the heat exchange position. The heat exchange position is used for contact with the fluid to be heated, and both ends of the heat exchange flow channel are connected to the heating box.

[0010] A circulating pump, connected to the heat exchange channel, is used to drive the heat exchange fluid to circulate between the heat exchange channel and the heating tank; and

[0011] An air supply structure is installed on the heat exchange structure and located at the installation position, and has an air inlet, an air supply channel and an air supply port connected in sequence, wherein the air supply port is used to output air.

[0012] In some embodiments, the heat exchange structure is provided with a mounting groove at the mounting position, the mounting groove extending along the flow direction of the heat exchange fluid, and opening on the side away from the heat exchange fluid;

[0013] The air supply structure is placed inside the mounting groove and fits against the inner wall of the mounting groove, and the air supply port is located on the side of the air supply structure near the opening.

[0014] In some embodiments, the inner wall of the heat exchange channel protrudes outward, and at least two heat exchange protrusions are formed on the outer wall surface of the heat exchange structure. The at least two heat exchange protrusions are spaced apart to form the mounting groove.

[0015] The heat exchange position is located on the outer wall surface of the heat exchange protrusion.

[0016] In some embodiments, at least two of the heat exchange protrusions are arranged at circumferential intervals along the heat exchange channel.

[0017] In some embodiments, one of the air supply structure and the inner wall of the mounting groove is provided with a magnetic attraction part and the other is provided with an adsorption part, wherein the magnetic attraction part can magnetically adsorb with the adsorption part.

[0018] In some embodiments, a thermally conductive silicone layer is provided between the air supply structure and the inner wall of the mounting groove, and the air supply structure is attached to the inner wall of the mounting groove via the thermally conductive silicone layer.

[0019] In some embodiments, the air supply structure is provided with a plurality of heat-conducting heads at intervals near the outer wall surface of the thermally conductive silicone layer, and the plurality of heat-conducting heads are inserted into the thermally conductive silicone layer.

[0020] In some embodiments, the air inlets are provided in multiple groups, and the multiple groups of air inlets are arranged sequentially along the flow direction of the heat exchange fluid, with the number of air inlets in each group gradually increasing along the flow direction of the heat exchange fluid.

[0021] In some embodiments, the heat exchange structure includes a heat exchange tube, which is spirally extended and its internal channels form the heat exchange flow channel.

[0022] The mounting position and the heat exchange position are located on the outer wall surface of the heat exchange tube, and their extension directions are the same as the extension direction of the heat exchange tube. The air supply structure is arranged along the extension direction of the heat exchange position.

[0023] Secondly, this utility model also provides a gasification vessel, which includes the separation and circulation device as described in any of the above claims.

[0024] Compared with the prior art, when using the separation and circulation device provided by this utility model, the heat exchange structure is placed inside the gasification vessel, and the heat exchange fluid is first heated to a preset temperature through a heating box during operation, and then the heat exchange fluid is driven by a pump to circulate between the heating box and the heat exchange channel.

[0025] Air is then supplied into the air supply channel of the air supply structure. Since the air supply structure is installed at the mounting position of the heat exchange structure, the air in the air supply channel can exchange heat with the heat exchange fluid in the heat exchange channel, thus preheating the air. The preheated air is then output from the air supply port. Simultaneously, liquid light hydrocarbons are supplied into the gasification vessel. When the liquid light hydrocarbons are immersed in the heat exchange structure, they directly contact the surface of the heat exchange position of the heat exchange structure, ensuring the heat exchange efficiency between the heat exchange fluid in the heat exchange channel and the liquid light hydrocarbons.

[0026] In this way, the heat exchange structure can heat both air and liquid light hydrocarbons simultaneously, thereby preheating the air, preventing cold air from directly contacting the liquid light hydrocarbons and absorbing their heat, and ensuring effective heat exchange between the liquid light hydrocarbons and the heat exchange structure. This improves the efficiency of light hydrocarbon fuel production, and the device is relatively compact, saving space. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0037] To address the technical problem in existing technologies where external air is directly blown into the light hydrocarbon solution through an air inlet pipe, causing the blown-in air to absorb heat from the light hydrocarbon solution and hindering the improvement of light hydrocarbon separation efficiency, this invention provides a separation and circulation device that can simultaneously heat air and liquid light hydrocarbons through a heat exchange structure. This achieves air preheating, avoids cold air directly contacting the liquid light hydrocarbons and absorbing heat from them, and ensures effective heat exchange between the liquid light hydrocarbons and the heat exchange structure, thereby improving the light hydrocarbon fuel production efficiency. Furthermore, the device is relatively compact and saves space.

[0038] It should be noted that the separation and circulation device described in this utility model is used in, but not limited to, reactors, etc. For ease of explanation, this utility model only uses the application of the separation and circulation device in a reactor as an example. The principle of the separation and circulation device in other types of equipment is essentially the same as that in a reactor, and will not be described in detail here.

[0039] Please see Figures 1 to 5 , Figures 1 to 5 This is a schematic diagram of the separation and circulation device and the gasification vessel 6 in one embodiment of the present invention. The separation and circulation device includes a heating box 1, a heat exchange structure 2, a circulation pump 3, and a gas supply structure 4. The heating box 1 is used to contain and heat the heat exchange fluid. The heat exchange structure 2 is provided with an installation position 21 and a heat exchange position 22, and has a heat exchange channel 2a flowing through the installation position 21 and the heat exchange position 22. The heat exchange position 22 is used for contact with the fluid to be heated. Both ends of the heat exchange channel 2a are connected to the heating box 1. The circulation pump 3 is connected to the heat exchange channel 2a and is used to drive the heat exchange fluid to circulate between the heat exchange channel 2a and the heating box 1. The gas supply structure 4 is installed on the heat exchange structure 2 and is located at the installation position 21. It has an air inlet, a gas supply channel 4a, and a gas supply port 4b connected in sequence. The gas supply port 4b is used to output air.

[0040] When using the separation and circulation device provided by this utility model, the heat exchange structure 2 is placed inside the vessel body 61 of the gasification vessel 6. During operation, the heat exchange fluid is first heated to a preset temperature by the heating box 1, and then the heat exchange fluid is driven by the pump to circulate between the heating box 1 and the heat exchange channel 2a.

[0041] Air is then supplied to the air supply channel 4a of the air supply structure 4. Since the air supply structure 4 is installed at the mounting position 21 of the heat exchange structure 2, the air in the air supply channel 4a can exchange heat with the heat exchange fluid in the heat exchange channel 2a, thus preheating the air. The preheated air is then output from the air supply port 4b. At the same time, liquid light hydrocarbons are supplied to the vessel body 61 of the gasification vessel 6. When the liquid light hydrocarbons are immersed in the heat exchange structure 2, they directly contact the surface of the heat exchange position 22 of the heat exchange structure 2, ensuring the heat exchange efficiency between the heat exchange fluid in the heat exchange channel 2a and the liquid light hydrocarbons.

[0042] In this way, the heat exchange structure 2 can heat both air and liquid light hydrocarbons simultaneously, thereby preheating the air, preventing cold air from directly contacting the liquid light hydrocarbons and absorbing their heat, and ensuring effective heat exchange between the liquid light hydrocarbons and the heat exchange structure 2. This improves the efficiency of light hydrocarbon fuel production, and the device is relatively compact, saving space.

[0043] It should be noted that light hydrocarbons generally refer to mixtures of hydrocarbons with boiling points below 200°C, encompassing C5-C10 carbon chain compounds. For example, C5 (pentane) has a boiling point of 36.1°C, while C6 (hexane) has a boiling point of approximately 68°C-70°C. Therefore, the preheating temperature of the heat exchange fluid is adjusted according to the corresponding light hydrocarbons produced. The heat exchange fluid can be water, ethanol, or butanone, etc. Specifically, in this embodiment, the heat exchange fluid is water.

[0044] In one embodiment, the heat exchange structure 2 is provided with an installation groove 21a at the installation position 21. The installation groove 21a extends along the flow direction of the heat exchange fluid and is open on the side away from the heat exchange fluid. The air supply structure 4 is placed in the installation groove 21a and fits against the inner wall of the installation groove 21a. The air supply port 4b is located on the side of the air supply structure 4 near the opening.

[0045] In this embodiment, the air supply structure 4 is placed in the mounting groove 21a and attached to the inner wall of the mounting groove 21a, increasing the contact area between the air supply structure 4 and the heat exchange structure 2, thereby improving the heat exchange efficiency between the air supply structure 4 and the heat exchange structure 2, and further improving the compactness of the device. Simultaneously, the air supply structure 4 can be snapped into the mounting groove 21a, enabling rapid installation of the air supply structure 4 and improving convenience.

[0046] In one embodiment, the inner wall of the heat exchange channel 2a protrudes outward, and at least two heat exchange protrusions 221 are formed on the outer wall surface of the heat exchange structure 2. The at least two heat exchange protrusions 221 are spaced apart to form an installation groove 21a; the heat exchange position 22 is located on the outer wall surface of the heat exchange protrusion 221.

[0047] In this embodiment, the inner wall of the heat exchange channel 2a is directly protruded outward to form a heat exchange protrusion 221, and the gas supply structure 4 is placed between the heat exchange protrusions 221 to minimize the wall thickness of the heat exchange structure 2 and ensure the contact area, so that the heat exchange fluid can quickly exchange heat with the light hydrocarbon solution and the gas supply structure 4.

[0048] In one embodiment, at least two heat exchange protrusions 221 are arranged circumferentially along the heat exchange channel 2a.

[0049] In this embodiment, the heat exchange protrusions 221 are arranged sequentially along the circumference of the heat exchange channel 2a, so that the heat exchange between the light hydrocarbon solution and the heat exchange protrusions 221, and between the gas supply structure 4 and the inner wall of the mounting groove 21a can be relatively evenly exchanged, ensuring the heat exchange effect between the two heat exchange parts and improving the compactness of the device.

[0050] In one embodiment, one of the air supply structure 4 and the inner wall of the mounting groove 21a is provided with a magnetic attraction part 5, and the other is provided with an adsorption part (not shown). The magnetic attraction part 5 can magnetically attract the adsorption part.

[0051] In this embodiment, the air supply structure 4 is magnetically attracted to the mounting groove 21a by the magnetic suction part 5 and the adsorption part, which prevents the air supply structure 4 from accidentally detaching from the mounting groove 21a and improves the installation stability of the air supply structure 4. At the same time, the air supply structure 4 can also be periodically removed from the mounting groove 21a to clean the scale between them and ensure the heat transfer effect.

[0052] It should be noted that one of the magnetic attraction part 5 and the adsorption part is a magnet, and the other is a magnet with opposite magnetic properties or an iron-cobalt-nickel metal. The magnet can be in the form of magnetic particles, magnetic strips, or magnetic blocks.

[0053] Specifically, in this design, the magnetic suction part 5 is configured as a magnetic strip and fixedly installed on the air supply structure 4. Simultaneously, the adsorption part is placed on the inner wall of the mounting groove 21a, and an iron-cobalt-nickel metal strip is placed on the inner wall of the mounting groove 21a corresponding to the magnetic strip.

[0054] In one embodiment, a thermally conductive silicone layer is provided between the air supply structure 4 and the inner wall of the mounting groove 21a, and the air supply structure 4 is attached to the inner wall of the mounting groove 21a via the thermally conductive silicone layer.

[0055] In this embodiment, thermally conductive silicone is provided between the air supply structure 4 and the inner wall of the mounting groove 21a to improve the fit between them, avoid gaps, and improve heat transfer efficiency. Simultaneously, because a thermally conductive silicone layer is provided between them, cleaning accumulated dirt only requires peeling off the silicone layer and reapplying new silicone, preventing dirt from adhering directly to the inner wall of the mounting groove 21a and becoming difficult to clean. It should be understood that in this case, the thermally conductive silicone layer is a liquid adhesive coating. The air supply structure 4 is installed after the liquid silicone is applied to the inner wall of the mounting groove 21a, and is used only after the thermally conductive silicone has solidified.

[0056] In one embodiment, the air supply structure 4 is provided with a plurality of heat-conducting heads at intervals on the outer wall surface near the thermally conductive silicone layer, and the plurality of heat-conducting heads are inserted into the thermally conductive silicone layer.

[0057] In this embodiment, multiple heat-conducting heads are provided on the surface of the air supply structure 4 to increase the heat transfer area between the air supply structure 4 and the thermally conductive silicone layer, thereby further improving the heat transfer efficiency. It should be noted that in this solution, the heat-conducting heads are relatively low, only extending into the thermally conductive silicone layer, and do not directly contact the inner wall of the mounting groove 21a.

[0058] In one embodiment, the air inlet 4b is provided in multiple groups, and the multiple groups of air inlets 4b are arranged sequentially along the flow direction of the heat exchange fluid, with the number of air inlets 4b in each group gradually increasing along the flow direction of the heat exchange fluid.

[0059] In this embodiment, the number of air inlets 4b is gradually increased along the flow direction of the heat exchange fluid, resulting in fewer air inlets 4b at the inlet end of the heat exchange channel 2a. At this time, the heat exchange time between the air and the heat exchange fluid in the air supply channel 4a is relatively short. On the other hand, the number of air inlets 4b at the outlet end of the heat exchange channel 2a is relatively large, resulting in a relatively longer heat exchange time between the air and the heat exchange fluid in the air supply channel 4a. This ensures the air supply flow rate while maximizing the temperature of the delivered air, thereby improving the production efficiency of light hydrocarbon fuel.

[0060] It should be noted that the air supply structure 4 can be configured as an air supply pipe, air supply box, or air supply plate with the aforementioned air supply channel 4a. Similarly, the heat exchange structure 2 can also be configured as a heat exchange pipe, heat exchange box, or heat exchange plate with a heat exchange channel 2a. Furthermore, it should be understood that the heating box 1 can be equipped with an electric heating rod inside or an electric heating coil inside its side wall to maintain the heat exchange fluid inside at a preset temperature.

[0061] In one embodiment, the heat exchange structure 2 includes a heat exchange tube that extends spirally and has an internal channel that forms a heat exchange flow channel 2a; the mounting position 21 and the heat exchange position 22 are located on the outer wall of the heat exchange tube and extend in the same direction as the heat exchange tube; the air supply structure 4 is arranged along the extension direction of the heat exchange position 22.

[0062] In this embodiment, the heat exchange tube is set in a spiral shape to increase the surface area of ​​the heat exchange tube, thereby increasing the contact area between the heat exchange tube, the gas supply structure 4 and the light hydrocarbon solution, and thus improving the heat exchange efficiency.

[0063] It should be noted that, in one embodiment, multiple mounting positions 21 and heat exchange positions 22 are provided, and the mounting positions 21 and heat exchange positions 22 are arranged alternately in sequence. Correspondingly, multiple air supply structures 4 are provided, and the multiple air supply structures 4 are respectively installed in multiple mounting positions 21, with each of the multiple air supply structures 4 corresponding to one of the multiple mounting positions 21. Specifically, in this solution, two mounting grooves 21a, two heat exchange protrusions 221, and two air supply structures 4 are provided.

[0064] Furthermore, this utility model also provides a gasification vessel 6, which includes the separation and circulation device described in any of the above embodiments. It should be noted that the detailed structure of the separation and circulation device of the gasification vessel 6 can be referred to the embodiments of the separation and circulation device described above, and will not be repeated here. Since the above-mentioned separation and circulation device is used in the gasification vessel 6 of this utility model, the embodiments of the gasification vessel 6 of this utility model include all the technical solutions of all the embodiments of the above-mentioned separation and circulation device, and the achieved technical effects are also completely the same, and will not be repeated here.

[0065] It should be noted that, in one embodiment, please refer to... Figure 6 and Figure 7 The gasification vessel 6 includes multiple separation and circulation devices, which are installed vertically at intervals within the vessel body 61. Specifically, in this design, three separation and circulation devices are spaced apart. Air is blown into the vessel body 61 by a blower 7 via an air supply channel. The blower 7 is located outside the vessel body 61 of the gasification vessel 6 and is connected to the air supply channel 4a of the air supply structure 4 via a guide pipe 71. Furthermore, the heating box 1 and the circulation pump 3 are located outside the vessel body 61 of the gasification vessel 6, and the heating box 1 is connected to both ends of the heat exchange channel 2a of the heat exchange structure 2 via a connecting pipe 11, and the circulation pump 3 is connected to the connecting pipe 11.

[0066] To better understand this utility model, the following is combined with... Figures 1 to 7 The technical solution of this utility model is described in detail below:

[0067] When using the separation and circulation device provided by this utility model, the heat exchange structure 2 is placed inside the vessel body 61 of the gasification vessel 6. During operation, the water is first heated to a preset temperature by the heating box 1, and then the water is driven by the pump to circulate between the heating box 1 and the heat exchange channel 2a.

[0068] Air is then supplied to the air supply channel 4a of the air supply structure 4. Since the air supply structure 4 is installed in the mounting groove 21a of the heat exchange structure 2, the air in the air supply channel 4a can exchange heat with the water in the heat exchange channel 2a through the inner wall of the mounting groove 21a, thus preheating the air. The preheated air is then output from the air supply port 4b. At the same time, liquid light hydrocarbons are supplied to the vessel body 61 of the gasification vessel 6. When the liquid light hydrocarbons are immersed in the heat exchange structure 2, they directly contact the surface of the heat exchange protrusion 221, ensuring the heat exchange efficiency between the water and the liquid light hydrocarbons in the heat exchange channel 2a.

[0069] In this way, the heat exchange structure 2 can heat both air and liquid light hydrocarbons simultaneously, thereby preheating the air, preventing cold air from directly contacting the liquid light hydrocarbons and absorbing their heat, and ensuring effective heat exchange between the liquid light hydrocarbons and the heat exchange structure 2, thus improving the efficiency of light hydrocarbon fuel production.

[0070] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
