Description

Technical Field

[0001] This utility model belongs to the field of refined benzene technology, specifically a refined benzene recycling device. Background Technology

[0002] In existing technologies, benzene is widely used as an important organic solvent and basic chemical raw material in chemical and related industrial production processes. However, in many production stages, such as petroleum refining, coal chemical industry, pharmaceuticals, and paint and coating manufacturing, benzene is generated in large quantities in the form of waste gas, waste liquid, or reaction residues. If these benzene-containing substances are directly emitted, it will not only cause serious environmental pollution and endanger the ecological balance and human health, but also pose risks of carcinogenesis, teratogenesis, and mutagenesis due to benzene being a toxic and harmful substance.

[0003] Meanwhile, benzene resources have high economic value, and with the development of the chemical industry, the market demand for benzene remains stable. Traditional treatment methods often focus on reducing pollutant emissions, neglecting the recovery and recycling of benzene resources. This leads to significant resource waste and is inconsistent with the current concepts of sustainable development and a circular economy. Therefore, the development of an efficient and reliable refined benzene recovery and utilization device is urgently needed.

[0004] Long-term observation revealed that refined benzene can be recycled and reused, which can effectively reduce resource waste.

[0005] Therefore, this utility model provides a device for the recovery and utilization of refined benzene. Utility Model Content

[0025] like Figures 1 to 4As shown in the embodiment of this utility model, a refined benzene recovery and utilization device includes a tank 1, a first conveying pipe 2, a condenser assembly 3, a gas-liquid separator body 4, a second conveying pipe 5, a heating furnace body 6, a storage tank 7, a third conveying pipe 8, a drain pipe 9, a baffle 100, a dredging hole 110, a flow limiting component 12, a protective component 13, a sealing ring 140, and a switching mechanism 15. One side of the tank 1 is fixedly installed with the first conveying pipe 2, the end of the first conveying pipe 2 away from the condenser assembly 3 is fixedly installed with the condenser assembly 3, the output end of the condenser assembly 3 is fixedly installed with the third conveying pipe 8, and the third conveying pipe 8 is away from the condenser assembly 3. One end is fixedly installed to the gas-liquid separator body 4, and the two sides of the gas-liquid separator body 4 are respectively fixedly installed to the second conveying pipe 5. The end of the left second conveying pipe 5 away from the gas-liquid separator body 4 is fixedly installed to the heating furnace body 6, and the end of the right second conveying pipe 5 away from the gas-liquid separator body 4 is fixedly installed to the liquid storage tank 7. The bottom of the liquid storage tank 7 is fixedly installed to the drain pipe 9. The inner wall of the drain pipe 9 is provided with a flow limiting component 12. The flow limiting component 12 can limit the liquid flow on the inner wall of the drain pipe 9 to ensure the safe outflow of the liquid. The flow limiting component 12 includes a flow limiting plate 121 and a rotating rod 122; the rotating rod 122 is fixedly installed on both sides of the flow limiting plate 121. On one side, the flow-limiting plate 121 is rotatably mounted on the inner wall of the drain pipe 9 via the rotating rod 122. A protective component 13 is provided on the inner wall of the drain pipe 9. The protective component 13 reduces friction between the drain pipe 9 and the flow-limiting component 12. The protective component 13 includes a fixing ring 131 and a roller 132. The fixing ring 131 is fixedly mounted on both sides of the drain pipe 9, and its inner wall is movably mounted to the roller 132. The rotating rod 122 is located on the side of the roller 132 away from the fixing ring 131, and is movably mounted to the roller 132. A switching mechanism 15 is provided on the inner wall of the drain pipe 9, which can open and close the drain pipe 9. The gate-closing mechanism 15 includes a flow-blocking ball 151, a screw 152, and a handle 153. The screw 152 is threadedly connected to one side of the drain pipe 9. One end of the screw 152 is fixedly installed with the flow-blocking ball 151, and the other end is fixedly installed with the handle 153. The flow-blocking ball 151 is slidably installed with the drain pipe 9. Three sets of partitions 100 are provided, and the three sets of partitions 100 are horizontally fixedly installed on the inner wall of the storage tank 7. The unblocking hole 110 is opened on the lower half of the surface of the partition 100. The two sides of the inner wall of the drain pipe 9 are fixedly installed with sealing rings 140, which are located on the side of the fixing ring 131 near the flow-limiting plate 121.

[0026] like Figures 1 to 4As shown, the baffle 100 can block the liquid inside the storage tank 7, preventing excessive pressure from damaging the storage tank 7. It also reduces liquid sloshing during transportation. The opening of the unblocking hole 110 allows liquid to flow between the various compartments, preventing excessive pressure from damaging the baffle 100. The combined use of the flow-limiting plate 121 and the rotating rod 122 can block the liquid flowing into the inner wall of the drain pipe 9, preventing excessive pressure from causing leakage and ensuring the safe flow of the chemical liquid. The fixing ring 1... The cooperation between roller 132 and 131 reduces friction between the rotating rod 122 and the drain pipe 9 during rotation, thus improving the service life of the drain pipe 9. The sealing ring 140 seals the drain pipe 9 to prevent leakage during liquid discharge, ensuring safe liquid discharge. The flow-blocking ball 151 seals the inner wall of the drain pipe 9, blocking the liquid flow. The cooperation between the screw 152 and handle 153 allows the operator to move the flow-blocking ball 151 by turning it.

[0027] Working Principle: During operation, first place the tank 1, condenser assembly 3, gas-liquid separator body 4, heating furnace body 6, and storage tank 7 on a level surface. Then, the user pours refined benzene into the tank 1. The condenser assembly 3 then draws the refined benzene from the tank 1 through the first conveying pipe 2 for condensation. The processed refined benzene flows into the gas-liquid separator body 4 through the third conveying pipe 8. The gas-liquid separator body 4 separates the refined benzene. The gas flows into the heating furnace body 6 through the second conveying pipe 5 for heating, while the liquid flows into the storage tank 7 through another set of second conveying pipes 5. When the refined benzene flows into the storage tank 7, it is blocked by the baffle 100. When the liquid pressure is too high, the refined benzene will flow through the unblocking hole 110. Entering another compartment for diversion, when the user needs to obtain the processed liquid, the user first turns the handle 153 to rotate the screw 152. When the screw 152 rotates, it will cause the flow-blocking ball 151 to move to one side. When the flow-blocking ball 151 moves, it will no longer block the liquid. The liquid inside the storage tank 7 will flow down through the drain pipe 9. When the liquid flows, the flow-limiting plate 121 will rotate due to the impact of the liquid. The rotation of the flow-limiting plate 121 will limit the flow rate of the liquid, preventing it from flowing out quickly. At the same time, when the flow-limiting plate 121 rotates, the sealing ring 140 will seal the drain pipe 9 to prevent liquid leakage. The roller 132 will roll to prevent friction between the flow-limiting plate 121 and the drain pipe 9 when the flow-limiting plate 121 rotates.
