Abstract

[0002] Methanol is a colorless, transparent, volatile, polar organic compound with the chemical formula CH3OH. It is toxic and flammable. As an important basic chemical raw material, it is widely used in the production of chemical products such as formaldehyde, acetic acid, and methyl tert-butyl ether. It also plays a key role in the field of new clean energy, serving as a raw material for methanol fuel and fuel cells. In addition, methanol has irreplaceable uses in the pharmaceutical, pesticide, and dye industries. Its chemical properties are active, and it is miscible with a variety of organic solvents such as water and ethanol. This characteristic makes it necessary to ensure the airtightness and stability of containers during storage and transportation.
[0003] Storage tanks are indispensable equipment in the industrial production, transportation, and use of methanol. However, existing storage tanks are prone to violent impacts when methanol is injected into them through pipelines due to unstable delivery pressure or sudden flow changes. This can cause liquid oscillation and increased foaming inside the tank, leading to methanol volatilization and loss. On the other hand, methanol produced in industrial production often contains mechanical impurities or other organic byproducts, which are difficult to separate and can affect subsequent production. To address these issues, we propose a methanol separation buffer storage tank. Utility Model Content

[0015] According to one embodiment of the present invention, in conjunction with the appendix Figure 1-4 As shown.
[0016] A methanol separation buffer tank includes an aluminum protective shell 1, a top cover 2 on top of the aluminum protective shell 1, a stainless steel inner shell 5 fixedly connected to the inner ring of the aluminum protective shell 1, a threaded connecting ring 7 fixedly connected to the inner ring of the stainless steel inner shell 5, a separation filter element 8 threadedly connected inside the threaded connecting ring 7, an injection pipe 9 fixedly connected to the upper surface of the top cover 2, an annular buffer plate 17 fixedly connected to the bottom end of the injection pipe 9, the bottom end of the injection pipe 9 being fixedly connected to the upper surface of the annular buffer plate 17, and multiple outlets on the outer surface of the bottom end of the injection pipe 9. The bottom surface of the annular buffer plate 17 has multiple sets of micro-leaks 4. The aluminum protective shell 1 serves as the outer protection layer, wrapped with a polyurethane insulation layer to reduce the influence of ambient temperature on the internal temperature of the tank. The stainless steel inner shell 5 is the direct cavity for methanol storage. The injection pipe 9 is the channel for methanol injection. The methanol can be initially dispersed through multiple outlet holes 10 to reduce the impact force during injection. The combination of the annular buffer plate 17 and the sets of micro-leaks 4 can further disperse the methanol, allowing the liquid to enter the stainless steel inner shell 5 in a smooth manner, thus achieving a buffering effect.
[0017] In this embodiment, the separating filter element 8 includes a filter cover 801. A first filter screen 802 and a second filter screen 804 are threadedly connected to the inner ring of the filter cover 801. A detection plate 803 is fixedly connected to the bottom end of the filter cover 801. An ultrasonic level gauge 805 is fixedly installed on the bottom surface of the detection plate 803. An annular threaded seat 3 is fixedly connected to the outer surface of the stainless steel inner shell 5. The inner ring of the annular threaded seat 3 is threadedly connected to the outer surface of the bottom end of the top cover 2. An annular sealing gasket 6 is provided on the inner bottom wall of the annular threaded seat 3. The upper surface of the annular sealing gasket 6 contacts the bottom end of the top cover 2. The upper surface of the top cover 2 is fixed... The tank is connected to a breather valve 15 and a filter cover 801, which provides an installation frame for the first filter screen 802 and the second filter screen 804. The first filter screen 802 and the second filter screen 804 can perform graded filtration of mechanical impurities and organic by-products. In addition, the ultrasonic level gauge 805 on the detection plate 803 can monitor the methanol level in the stainless steel inner shell 5 in real time and then transmit it to an external display device for easy monitoring of the storage volume. The tank is connected to the top cover 2 by a threaded annular threaded seat 3 and a ring-shaped sealing gasket 6 to enhance the sealing performance of the tank and prevent methanol leakage. The breather valve 15 can balance the air pressure inside the tank.
[0018] In this embodiment, the aluminum protective shell 1 is provided with a drain pipe 18 on its exterior. One end of the drain pipe 18 passes through the aluminum protective shell 1 and the stainless steel inner shell 5 and extends into the interior of the stainless steel inner shell 5. The outer surface of the drain pipe 18 is fixedly connected to an outlet valve 11. The bottom surface of the stainless steel inner shell 5 is fixedly connected to a sedimentation drain pipe 12. The outer surface of the sedimentation drain pipe 12 is fixedly connected to a drain valve 13. The outer surface of the aluminum protective shell 1 is fixedly connected to a ring-shaped arrangement of lifting components 16. The bottom surface of the aluminum protective shell 1 is fixedly connected to a ring-shaped arrangement of support seats 14. The drain pipe 18 is used to discharge purified methanol. The outlet valve 11 can control the drainage process and facilitate on-demand use. The sedimentation drain pipe 12 and the drain valve 13 are used to discharge fine impurities deposited at the bottom of the stainless steel inner shell 5 to avoid impurity accumulation affecting the purity of methanol. The ring-shaped arrangement of lifting components 16 on the outer surface of the aluminum protective shell 1 facilitates the lifting, handling and installation of the storage tank. The support seats 14 enhance the stability of the storage tank when it is placed.
[0019] Working principle: When methanol is delivered from the injection pipe 9 into the stainless steel inner shell 5, it first flows out through multiple outlet holes 10 to initially reduce the liquid impact pressure. Then, the liquid flows into the top of the annular buffer plate 17 and is further dispersed by multiple sets of micro-leakage holes 4, so that the methanol can slowly fall into the stainless steel inner shell 5 in the form of a fine liquid flow. After the methanol liquid enters the stainless steel inner shell 5, it flows through the separation filter element 8 inside the threaded connecting ring 7. The first filter screen 802 inside the filter cover 801 can intercept mechanical impurities, and the second filter screen 804 further filters organic by-products, realizing the graded separation of impurities in the methanol. The separated methanol is stored at the bottom of the stainless steel inner shell 5, while the fine impurities that are not completely filtered and settled will accumulate at the bottom of the stainless steel inner shell 5 and can be discharged periodically through the sedimentation drain pipe 12 and the drain valve 13. When methanol is needed, the liquid outlet valve 11 on the drain pipe 18 can be opened to output the buffered and separated methanol.
[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
