Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooler equipment, specifically a gas-liquid separation device for a methanol cooler. Background Technology
[0002] Methanol, also known as hydroxymethane, wood alcohol, or wood spirit, is a basic organic compound, belonging to the simplest category of saturated monohydric alcohols, with the chemical formula CH3OH or CH4O. Its molecular weight is 32.04, and its boiling point is 64.7℃. Methanol is a colorless and volatile liquid with a distinctive alcoholic odor, similar to ethanol (the main component of alcoholic beverages), but its toxicity is far greater than ethanol. Methanol has a low density and is somewhat flammable. Cooling treatment is required at several stages in the methanol production process.
[0003] The core function of a methanol cooling unit is to reduce the temperature of methanol or related products to the required range to ensure the smooth operation of subsequent processes. In current technology, methanol cooling units typically consist of a cooling tank with a base fixed to the bottom. Two conveying pipes extend into the tank from either side, each equipped with a valve at one end. A cooling pipe connects the two conveying pipes, and supports are installed around the cooling pipe. Although this device can effectively cool methanol, leaks can still occur during the cooling process. If a leak occurs, a high-temperature methanol-water mixture will be ejected, causing serious harm to the surrounding environment. Utility Model Content

[0025] Methanol leaks can occur during the cooling process. In the event of a leak, hot methanol and water can erupt, causing serious environmental damage. This invention provides a gas-liquid separation device for methanol coolers, aiming to solve the safety handling problem of leaks during methanol cooling.
[0026] like Figures 1-4 As shown, in some embodiments, a gas-liquid separation device for a methanol cooler includes a cooling tank 1, a cooling water supply assembly, and a gas-liquid separation assembly. The cooling water supply assembly is installed at one end of the cooling tank 1 and is used for circulating the cooling water within the tank 1. The gas-liquid separation assembly is in close communication with the cooling water supply assembly, effectively separating the high-temperature gas and water after a methanol leak, allowing the high-temperature gas and water to be discharged separately through different pipes, ensuring operator safety.
[0027] In detail, the gas-liquid separation assembly includes an overflow pipe 13, a drain pipe 8, and an exhaust pipe 6. The overflow pipe 13 is directly connected to the cooling water supply assembly, ensuring that the high-pressure fluid generated instantaneously after a leak is discharged through the cooling water supply assembly from the overflow pipe 13, preventing excessive pressure inside the cooling tank 1 and thus avoiding an explosion of the cooling tank 1 and a larger safety accident. It also prevents the accumulation of methanol gas in the cooling tank 1. The drain pipe 8 is connected to the overflow pipe 13, forming a continuous fluid channel that allows the liquid to separate from the gas, with the liquid falling from the drain pipe 8 to an externally connected container. Furthermore, the exhaust pipe 6 is also connected to the overflow pipe 13, but its opening is positioned relatively low, allowing it to effectively discharge any escaped methanol gas.
[0028] It should be noted that the overflow pipe 13 is connected to the cooling water supply assembly, so that the high-pressure fluid can be discharged from the overflow pipe 13, avoiding excessive pressure in the cooling tank 1 and thus preventing damage to the cooling tank 1. When the fluid passes through the interface between the overflow pipe 13 and the drain pipe 8, the liquid in the fluid can fall from the drain pipe 8 due to gravity, realizing the separation of gas and liquid, and preventing high-temperature liquid from spraying out from the exhaust pipe 6.
[0029] Furthermore, in some embodiments, the gas-liquid separation assembly also includes a first safety valve 5, a second safety valve 12, and an anti-overflow three-way valve 4. The second safety valve 12 is located on the overflow pipe 13, and the drain pipe 8 is located below the second safety valve 12. In the event of a small leak, the mixed fluid can be directly discharged from the drain pipe 8. The anti-overflow three-way valve 4 connects the overflow pipe 13 and the exhaust pipe 6, thus providing a safe discharge path in the event of gas overflow. The first safety valve 5 is installed on the exhaust pipe 6, which is responsible for communicating with the outside air to ensure that the gas can be smoothly discharged from the system.
[0030] It is worth noting that the first safety valve 5 and the second safety valve 12 are normally closed under normal operating conditions. This means that they will only open when the pressure in the pipeline reaches a specific safety threshold, thus ensuring the stability and safety of the entire system.
[0031] This design reduces the impact of leaks through effective gas-liquid separation, thereby ensuring the reliability and safety of the entire cooling system.
[0032] Furthermore, in some embodiments, the cooling water supply assembly includes a cooling water inlet pipe 16, a first regulating valve 9, a cooling water outlet pipe 3, and a second regulating valve 14. Specifically, the second regulating valve 14 is located on the cooling water outlet pipe 3, and its main function is to control the flow rate of the cooling water outlet pipe 3, thereby ensuring that the water flow rate reaches the expected level during the cooling process. Simultaneously, an overflow pipe 13 is located above the second regulating valve 14, its purpose being to allow leaked fluid to be discharged from the overflow pipe 13 in the event of a leak. In addition, the first regulating valve 9 is located on the cooling water inlet pipe 16, and its function is to regulate the amount of water entering the cooler to adapt to different cooling requirements. These two regulating valves, namely the first regulating valve 9 and the second regulating valve 14, work together to ensure the high efficiency and stability of the cooling process by precisely controlling the water supply of the cooling water supply assembly, thereby improving the performance of the entire cooling system.
[0033] To ensure continuous operation of the cooling system, the cooling water inlet pipe 16 and the cooling water outlet pipe 3 are connected to an external water tank. This design allows the cooling water to be recycled, improving cooling efficiency.
[0034] Furthermore, in some embodiments, the device also includes a stationary assembly and a methanol delivery assembly. Specifically, the stationary assembly is connected to the cooling tank 1, the cooling water supply assembly, the gas-liquid separation assembly, and the methanol delivery assembly, respectively. This design ensures the stability between the various components.
[0035] Furthermore, the methanol delivery assembly is connected to the cooling tank 1, enabling methanol to be efficiently delivered from the cooling tank 1, further improving the cooler's efficiency and methanol processing capacity. This design not only optimizes the cooling process but also ensures the safety and stability of methanol during delivery, thereby enhancing the overall system performance and reliability.
[0036] Furthermore, in some embodiments, the fixing assembly includes a first fixing post 7, a second fixing post 15, and a fixing base 10. The first fixing post 7 is fixedly connected to the outer wall of the exhaust pipe 6 and is positioned at the opening of the exhaust pipe 6. This ensures the stability of the exhaust pipe 6, preventing displacement and unnecessary damage during gas emission. The second fixing post 15 is connected to the methanol delivery assembly.
[0037] Furthermore, there are multiple mounting bases 10 arranged along the bottom of the cooling tank 1, and each mounting base 10 is connected to the cooling tank 1. This design ensures the stability and durability of the device, enabling it to maintain good operating conditions under high temperature and high pressure environments, thereby improving the safety of the methanol cooler.
[0038] Furthermore, in some embodiments, the cooling tank 1 is specially designed with a cooling chamber inside. Cooling water is filled between the cooling tank 1 and the cooling chamber to ensure that methanol can be effectively cooled during the cooling process.
[0039] The methanol delivery assembly includes an inlet pipe 2 and an outlet pipe 11. Specifically, the inlet pipe 2 and the cooling water supply assembly are located at the same end of the cooling tank 1, while the outlet pipe 11 is located at the other end of the cooling tank 1. The inlet pipe 2 and the outlet pipe 11 are respectively connected to the cooling chamber, ensuring the effective delivery of methanol during the cooling process.
