Technical Field
[0001] This utility model relates to the field of crude benzene processing, and in particular to a waste gas recovery device for crude benzene hydrogenation production. Background Technology
[0002] The production of crude benzene hydrogenation is a process that converts crude benzene into a purer product or uses it in the production of subsequent chemicals through a hydrogenation reaction. The main objectives of crude benzene hydrogenation production usually include removing impurities from benzene, improving product quality, or converting benzene into other chemicals.
[0003] The production of crude benzene hydrogenation often generates a lot of waste gas. This waste gas usually contains unreacted hydrogen, volatile organic compounds, low molecular weight hydrocarbons and other potentially harmful gases. In order to reduce environmental pollution and improve resource utilization, it is necessary to use waste gas recovery devices to recover the waste gas.
[0004] However, in the use of existing waste gas recovery devices, the pipes are usually connected using flanges and bolts, which makes the installation process more complicated. This results in a long installation time and affects the efficiency of the waste gas recovery device, making it difficult to quickly install and disconnect the connecting pipes.
[0005] Furthermore, the ventilation area of the connecting pipes of existing waste gas recovery devices is usually fixed. When the amount of waste gas is large, the ventilation volume inside the pipe increases, which leads to increased fluid resistance inside the pipe, which can easily cause pipe damage and affect the service life of the waste gas recovery device. In other words, it is difficult to meet the needs of various working scenarios.
[0006] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1:
[0029] This embodiment addresses the problem that in existing waste gas recovery devices, pipes are typically connected using flanges and bolts, resulting in a complex installation process that leads to prolonged installation time and reduces the efficiency of the waste gas recovery device, making it difficult to quickly install and dismantle the connecting pipes.
[0030] Please see Figure 1 - Figure 4 As shown, this embodiment is a waste gas recovery device for crude benzene hydrogenation production, including a tank 1 and a tank 2 11. The tank 1 and the tank 2 11 are fixedly connected by a recovery component 2. The recovery component 2 includes a connecting pipe 21, a bend 22 and a horizontal pipe 23. The tank 2 11 is a waste gas treatment device, and the tank 1 is a crude benzene hydrogenation production device. Waste gas is generated during the production process, and the waste gas enters the waste gas treatment device through the recovery component 2.
[0031] The top of the connecting pipe 21 is fixedly mounted with a fixing plate 24, the bend pipe 22 is fixedly mounted with a mounting base plate 41, the bottom of the mounting base plate 41 is fixedly mounted with a limiting block 26, the fixing plate 24 is movably mounted with a plug rod 27, the limiting block 26 has a plug hole 28, and one end of the plug rod 27 is located in the plug hole 28.
[0032] A connecting block 34 is fixedly installed at the bottom of the fixing plate 24, and a fixing tube 40 is fixedly installed on the connecting block 34. The insertion rod 27 is movably installed in the fixing tube 40, and a reset plate 35 is movably installed in the fixing tube 40. The reset plate 35 is fixedly connected to the insertion rod 27. A spring is fixedly installed on one side of the reset plate 35, and one end of the spring is fixedly connected to the inner wall of the fixing tube 40. When connecting the tank 1 and the tank 21, the insertion rod 27 is pulled. At this time, the spring is compressed, and the limiting block 26 is inserted into the fixing plate 24. The pulling of the insertion rod 27 is stopped. Under the action of the spring, one end of the insertion rod 27 is inserted into the insertion hole 28, thereby realizing the fixed connection between the fixing plate 24 and the mounting base plate 41.
[0033] There are three insertion rods 27. The stability of the connection is ensured by the multiple insertion rods 27. The three insertion rods 27 are evenly distributed at intervals at the bottom of the fixing plate 24.
[0034] When connecting tank 1 and tank 21, simply pull the insertion rod 27 and insert the limiting block 26 into the fixing plate 24. At this time, the mounting base plate 41 and the fixing plate 24 are in contact. Stop pulling the insertion rod 27, and the insertion rod 27 will automatically insert into the insertion hole 28. The fixing plate 24 and the mounting base plate 41 are fixedly connected by the insertion rod 27 and the insertion hole 28. The installation is convenient and the connection efficiency is high.
[0035] Example 2:
[0036] This embodiment addresses the problem that the ventilation area of the connecting pipes in existing waste gas recovery devices is usually fixed. When the amount of waste gas is large, the ventilation volume inside the pipe increases, which leads to increased fluid resistance inside the pipe, easily causing pipe damage and affecting the service life of the waste gas recovery device, making it difficult to meet the needs of various working scenarios.
[0037] Please see Figure 5 As shown, this utility model also includes a connecting plate 25. The connecting plate 25 is fixedly installed on one side of the tank body 1. A support block 29 is fixedly installed on the connecting plate 25. The recovery component 2 also includes an airbag 30, an airbag 31, an airbag 32 and an airbag 33. The airbag 30 is fixedly installed in the support block 29. The airbags 31 and 32 are both fixedly installed on the connecting plate 25. The airbag 33 is fixedly installed in the horizontal tube 23.
[0038] Airbag 1 30 is fixedly connected to airbag 2 31 via a pipeline, and airbag 32 is fixedly connected to airbag 4 33 via a pipeline. An electric push rod 36 is fixedly installed on the connecting plate 25, and a compression plate 37 is fixedly installed at the output end of the electric push rod 36. Airbag 2 31 is fixedly installed at the bottom of the compression plate 37, and airbag 32 is fixedly installed at the top of the compression plate 37. A limit plate 38 is fixedly installed on the connecting plate 25, and the top of airbag 32 is fixedly connected to the limit plate 38. When the electric push rod moves the compression plate 37 upward, airbag 32, located between the compression plate 37 and the limit plate 38, is compressed and begins to contract, while airbag 2 31, located at the bottom of the compression plate 37, begins to expand. That is, the changes of airbag 32 and airbag 2 31 are always opposite.
[0039] The top of the support block 29 is provided with a slot 39, and the airbag 30 is fixedly installed in the slot 39. There are multiple support blocks 29, which are located on both sides of the horizontal pipe 23. In the initial state, the pipe is clamped and fixed by the airbag 30 and the slot 39 to ensure the stability of the pipe during use.
[0040] When the amount of exhaust gas in tank 1 increases, airbag 32 expands while airbag 2 gradually contracts. When airbag 32 expands, airbag 4 gradually contracts. At this time, the ventilation area in the horizontal pipe 23 increases, improving the exhaust gas discharge efficiency and preventing excessive air pressure inside the pipe from damaging it. When airbag 2 contracts, airbag 30 gradually expands. Airbag 30 clamps the bend 22, improving the stability of the bend 22 and the horizontal pipe 23 and preventing them from vibrating too much due to the increased ventilation volume. This meets the needs of various working scenarios.
[0041] Combining Embodiments 1 and 2, when connecting Tank 1 and Tank 2, it is only necessary to pull the insertion rod 27 and insert the limiting block 26 into the fixing plate 24. At this time, the mounting base plate 41 and the fixing plate 24 are in contact. When pulling the insertion rod 27 stops, the insertion rod 27 automatically inserts into the insertion hole 28. The fixing plate 24 and the mounting base plate 41 are fixedly connected by the insertion rod 27 and the insertion hole 28. The installation is convenient and the connection efficiency is high. At the same time, when the airbag 32 expands, the airbag 43 gradually contracts. At this time, the ventilation area in the horizontal pipe 23 increases, improving the exhaust gas discharge efficiency and avoiding excessive air pressure inside the pipe, which could damage the pipe. When the airbag 231 contracts, the airbag 30 gradually expands. The airbag 30 clamps the bend 22, improving the stability of the bend 22 and the horizontal pipe 23 and preventing large vibrations due to increased ventilation. This meets the needs of various working scenarios.
[0042] The working process and principle of this utility model are as follows:
[0043] First, when connecting tank 1 and tank 21, simply pull the insert rod 27 and insert the limiting block 26 into the fixing plate 24. At this time, the mounting base plate 41 and the fixing plate 24 are in contact. Stop pulling the insert rod 27, and the insert rod 27 will automatically insert into the insertion hole 28. The fixing plate 24 and the mounting base plate 41 are fixedly connected by the insert rod 27 and the insertion hole 28. The installation is convenient and the connection efficiency is high.
[0044] Furthermore, when airbag 32 expands, airbag 4 33 gradually contracts. At this time, the ventilation area in the horizontal pipe 23 increases, improving the exhaust gas discharge efficiency and preventing excessive air pressure inside the pipe from damaging the pipe.
[0045] Furthermore, when the second airbag 31 contracts, the first airbag 30 gradually expands, clamping the bend 22 through the first airbag 30, improving the stability of the bend 22 and the horizontal tube 23, and preventing them from vibrating too much due to the increased ventilation volume, thereby meeting the needs of various working scenarios.
[0046] This utility model achieves rapid connection of pipelines through the set recycling component 2, and the ventilation area inside the pipeline can be flexibly adjusted to meet the needs of various working scenarios.
