Description

Technical Field

[0001] This utility model relates to the field of reflux tank technology, specifically to a reflux tank for reducing the odor of propylene glycol. Background Technology

[0002] During the production process, propylene glycol materials are prone to insufficient gas-liquid mixing when transported at high speeds, making it difficult to effectively separate volatile gases and thus producing a persistent odor. Existing reflux tanks cannot effectively solve the above problems. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a reflux tank for reducing the odor of propylene glycol. This tank is used to solve the problem that during the production process, propylene glycol materials are easily transported at high speeds, which can lead to insufficient gas-liquid mixing and difficulty in effectively separating volatile gases, resulting in a persistent odor.

[0004] One embodiment of this utility model provides a reflux tank for reducing the odor of propylene glycol, comprising: a tank body, wherein the tank body is provided with a feed inlet;

[0005] A baffle structure is installed on the inner wall of the tank.

[0006] A collection structure is installed on the tank body and located below the baffle structure;

[0007] The baffle structure is used for initial separation of liquid and gas, and the collection structure is provided with several through holes and is used for slow liquid output.

[0008] This utility model discloses a reflux tank for reducing the odor of propylene glycol. The inlet is used to transport materials into the tank. During the transport process, the material is first splashed onto a baffle structure, where it briefly lingers. This brief lingering of the material on the baffle allows for the storage and separation of liquid and gas. The generated gas overflows from the baffle structure and accumulates near the top of the tank, while the liquid flows out from the baffle structure and onto a collection structure. The flow rate of the material can be controlled through the through-holes in the collection structure, ensuring that some material remains on the collection structure for a certain period. During this time, some gas will still accompany the material. While the material is stationary, some gas will move towards the top of the lid. The remaining gas, after separating from the liquid as it flows towards the bottom of the tank, moves towards the top of the lid, thus better reducing the odor of propylene glycol.

[0009] In one embodiment, the top of the tank is provided with a cover.

[0010] In one embodiment, the baffle structure includes a baffle body and a plurality of baffle strips.

[0011] In one embodiment, the baffle body is installed on the inner wall of the tank, and the baffle body is located on one side of the feed inlet.

[0012] In one embodiment, the plurality of baffles are mounted in a regular array on the baffle body, and the baffle body is located on the side of the baffle body facing the feed inlet.

[0013] In one embodiment, the collection structure includes an annular collection disk;

[0014] The annular collecting tray is installed on the inner wall of the tank, and several through holes are formed on the annular collecting tray.

[0015] In one embodiment, a gas phase space and a liquid phase space are formed inside the tank, with the liquid phase space located below the gas phase space.

[0016] In one embodiment, an annular weir plate is provided inside the tank, and the annular weir plate is fixedly disposed on the annular collection tray.

[0017] In one embodiment, the height of the annular weir plate is less than the height of the baffle structure.

[0018] In one embodiment, liquid outlet holes are provided on both sides of the baffle structure.

[0019] The reflux tank for reducing propylene glycol odor provided by the above technical solution has the following beneficial effects:

[0020] 1. The inlet is used to transport materials into the tank. During the transport process, the material will first splash onto the baffle structure. The material will be briefly suspended on the baffle, during which the liquid and gas of the material are stored and separated. The generated gas overflows from the baffle structure and accumulates near the top of the tank, while the liquid flows out from the baffle structure and onto the collection structure. The flow rate of the material can be controlled through the through holes in the collection structure, so that some material will remain on the collection structure for a certain period of time. At this time, some gas will still follow the material. When the material is stationary, some gas will move towards the top of the cover. The remaining gas will separate from the liquid as it flows towards the bottom of the tank and then move towards the top of the cover, thereby better reducing the odor of propylene glycol.

[0021] 2. By using several baffles, the material ejected from the discharge port can be divided into multiple layers of jets that are ejected from both sides of the baffle, thereby increasing the suspension time of the material and the contact area with the air, and improving the efficiency of gas-liquid separation.

[0037] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the so-called equivalent implementations or modifications of the present utility model should be included in the patent scope of this case.

[0038] Combination Figures 1 to 5 As shown, one embodiment of this utility model provides a reflux tank for reducing the odor of propylene glycol, comprising:

[0039] Tank body 100, wherein a feed inlet 101 is provided on the tank body 100;

[0040] A baffle structure 200 is installed on the inner wall of the tank body 100;

[0041] A collection structure 300 is installed on the tank 100 and located below the baffle structure 200;

[0042] The baffle structure 200 is used for initial separation of liquid and gas, and the collection structure 300 is provided with a plurality of through holes 320, and the collection structure 300 is used for slow output of liquid.

[0043] This utility model discloses a reflux tank for reducing the odor of propylene glycol. The inlet 101 is used to transport materials into the tank body 100. During the transport process, the material is first splashed onto the baffle structure 200, where it briefly lingers. This allows for the storage and separation of the liquid and gas components. The generated gas overflows from the baffle structure 200 and accumulates near the top of the tank body 100, while the liquid flows out from the baffle structure 200 and onto the collection structure 300. The flow rate of the material can be controlled through the through-hole 320 on the collection structure 300, ensuring that some material remains on the collection structure 300 for a certain period of time. During this time, some gas will still accompany the material. While the material is stationary, the remaining gas will move towards the top of the cover 400, thereby better reducing the odor of propylene glycol.

[0044] It should be noted that when the material is sprayed from the feed inlet 101 to the baffle structure 200, a brief period of stagnation is formed due to the impact, achieving preliminary gas-liquid separation; the through hole 320 of the collection structure 300 controls the liquid to flow out slowly, prolonging the residence time and causing the residual gas to float up, significantly reducing the volatile odor of propylene glycol.

[0045] In one embodiment, the top of the tank 100 is provided with a cover 400.

[0046] In this embodiment, the cover 400 seals the gas phase space 500, preventing odor leakage and providing a sealed environment for gas accumulation, thereby enhancing the separation effect.

[0047] In one embodiment, the baffle structure 200 includes a baffle body 210 and a plurality of baffle strips 220.

[0048] In this embodiment, the baffle 220 divides the material into multi-layer jets, increasing the gas-liquid contact area and improving separation efficiency.

[0049] In one embodiment, the baffle body 210 is installed on the inner wall of the tank 100, and the baffle body 210 is located on one side of the feed inlet 101;

[0050] The plurality of baffles 220 are mounted in a regular array on the baffle body 210, and the baffle body 210 is located on the side of the baffle body 210 facing the feed inlet 101.

[0051] In this embodiment, the sprayed material is accurately received, and the regularly arrayed baffles 220 evenly disperse the impact force, avoiding local splashing and ensuring a stable gas escape path. Furthermore, the material sprayed through the outlet can be subdivided into multiple jets that are ejected from both sides of the baffle by several baffles, thereby increasing the suspension time of the material and the contact area with the air, and improving the efficiency of gas-liquid separation.

[0052] It should be noted that the above description of a regular array refers to a vertical array (e.g., Figure 5 As shown), the sprayed material can be moved along both sides of the baffle 220. The width of the baffle 220 is equivalent to half the width of the baffle body 210, or slightly smaller than the width of the baffle body 210. The baffle 220 has a certain width so that most of the sprayed material is located on the baffle 220.

[0053] In one embodiment, the collection structure 300 includes an annular collection disk 310;

[0054] The annular collecting tray 310 is installed on the inner wall of the tank 100, and a plurality of through holes 320 are formed on the annular collecting tray 310.

[0055] In this embodiment, the annular design expands the liquid distribution area, and the through-hole 320 helps control the flow rate, prolonging the gas-liquid secondary separation time and completely releasing residual gas.

[0056] It should be noted that the size of the through hole 320 can be determined based on the material residence time, the surface area of ​​the collection tray, the pressure inside the tank, and the material flow rate, and is not limited to a single value here.

[0057] In one embodiment, a gas phase space 500 and a liquid phase space 600 are formed inside the tank 100, with the liquid phase space 600 located below the gas phase space 500.

[0058] In this embodiment, the clear division between the liquid phase at the bottom and the gas phase at the top conforms to the natural law of gas rising, accelerating the separation of odorous gases from the liquid.

[0059] In one embodiment, an annular weir plate 700 is provided inside the tank 100, and the annular weir plate 700 is fixedly disposed on the annular collection tray 310;

[0060] The height of the annular weir plate 700 is less than the height of the baffle structure 200.

[0061] In this embodiment, the anti-backflow block is used to prevent excessive liquid accumulation from exceeding the height of the inlet 101, thereby causing liquid backflow. The excess liquid flows out through the through hole 320 of the annular weir plate 700.

[0062] In one embodiment, liquid outlet holes 230 are provided on both sides of the baffle structure 200.

[0063] In this embodiment, the dual-outlet design balances the liquid flow, reduces eddy current generation, and further reduces the risk of gas entrainment.

[0064] It should be noted that the bottom of tank 100 is not sealed, but rather open, which facilitates the transfer of materials to the next production line.

[0065] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made using the paper parts and drawings of the present utility model under the inventive concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
