Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crude benzene processing, in particular to a crude benzene dehydration device and processing equipment. Background Art
[0002] At present, in the production and processing of crude benzene, crude benzene dehydration is one of the necessary processing links. Crude benzene dehydration usually refers to leaving the mixture of crude benzene and water in a crude benzene storage tank for more than 12 hours, and using the different densities of crude benzene and water to separate the crude benzene and water. The density of crude benzene is smaller than that of water, so it is in the upper layer and water is in the lower layer. Then the bottom of the crude benzene storage tank is drained through a pipeline, and the lower layer water flows into the crude benzene separation water drain tank.
[0003] In the prior art, in the above-mentioned crude benzene dehydration process, an open funnel is generally used to catch the crude benzene separated water flowing out of the crude benzene storage tank and then introduce it into the drain tank, so as to observe the size of the water flow and other factors to judge the dehydration progress. However, in this process, since the funnel is open, the crude benzene is highly volatile. During the entire dehydration period, the benzene smell is very strong on site and blows away by the wind, polluting the environment. It is also easy to cause benzene poisoning and occupational diseases, affecting the health of employees. In addition, if the crude benzene dehydration pipeline is blocked, crude benzene may overflow from the funnel. Crude benzene is flammable and explosive, which will pose a huge safety and environmental hazard. Utility Model Content

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.
[0026] To solve the above technical problems, Figure 1 As shown, an embodiment of the utility model provides a crude benzene dehydration device, including a first pipeline 10, a transfer tube 50, a peephole 60 and a second pipeline 20, one end of the first pipeline 10 is used to communicate with the crude benzene storage tank 01, the other end of the first pipeline 10 is connected to the side of the pipe wall of the transfer tube 50, one end of the second pipeline 20 is connected to the lower part of the pipe wall of the transfer tube 50, the other end of the second pipeline 20 is used to communicate with the venting tank 02, and the peephole 60 is connected to the axial end of the transfer tube 50 so that the transfer tube 50 forms a closed cavity.
[0027] It should be noted that if Figure 1 As shown, Figure 1 01 is a schematic diagram of the structure of the crude benzene dehydration device of this embodiment, wherein the structures and sizes of the structural components, such as the crude benzene storage tank 01 and the venting tank 02, are only for illustration, wherein the crude benzene storage tank 01 is a component for temporarily storing a mixture of crude benzene and water, and the density of crude benzene is less than the density of water. Therefore, when performing the crude benzene dehydration operation, the mixture of crude benzene and water can be allowed to stand in the crude benzene storage tank 01 for, for example, 12 hours, and the first pipeline 10 can be connected to the lower end of the crude benzene storage tank 01 to divert the crude benzene separated water. At the same time, a control valve can be set on the first pipeline 10 to regulate the on-off of the water flow, and the peephole 60 can be transparent and waterproof. The transfer tube 50 is made of corrosive materials, such as tempered glass, and has a firm and stable structure and is convenient for observation. The transfer tube 50 can be a tubular structure or a cylindrical structure, that is, the axial ends of the transfer tube 50 can be fully open structures or structures with one end closed and the other end open. Therefore, the number of the peepscope 60 can be two or one, that is, it can be connected to the two ends or one end of the transfer tube 50. Of course, as long as the flow size or other state of the separated water in the transfer tube 50 can be observed through the peepscope 60, and the transfer tube 50 can be formed into a closed cavity to prevent the crude benzene from volatilizing or overflowing into the external environment, its specific structure and connection form are not specifically limited again. In addition, the second pipeline 20 is connected to the lower part of the pipe wall of the transfer tube 50 to facilitate the outflow of the crude benzene separated water. At the same time, a control valve can also be set on the second pipeline 20 to regulate the flow rate and on-off of the vent tank 02 storing the crude benzene separated water.
[0028] In this embodiment, the crude benzene dehydration device provided in this embodiment can be applied to the crude benzene dehydration operation in the crude benzene production and processing, by providing a first pipeline 10, a transfer pipe 50 and a second pipeline 20 which are connected in sequence, the first pipeline 10 can be connected to the crude benzene storage tank 01 storing a mixture of crude benzene and water, and is connected to the side of the pipe wall of the transfer pipe 50 through the first pipeline 10, and the crude benzene separation water can be drained to the transfer pipe 50, and is connected to the lower part of the pipe wall of the transfer pipe 50 through the second pipeline 20, and the second pipeline 20 can be connected to the drain tank 02 accommodating the crude benzene separation water, and the crude benzene separation water can be drained to the drain tank 02, and so on. The crude benzene dehydration operation is completed. At the same time, by connecting a peephole 60 to the axial end of the transfer tube 50, the operator can observe the water flow size during the crude benzene dehydration process through the peephole 60 to judge the dehydration progress, and the peephole 60 can form a closed cavity in the transfer tube 50 to prevent harmful gases such as crude benzene from volatilizing to the outside world, and to prevent overflow caused by pipeline blockage, etc., to prevent environmental pollution and harm to operators, which is safe and environmentally friendly. Moreover, through the closed observable structure of the peephole 60 and the transfer tube 50, the flow rate of the crude benzene separation water can be increased, the dehydration process can be accelerated, and the efficiency of the crude benzene dehydration operation can be improved.
[0029] Alternatively, if Figure 1 As shown, the adapter tube 50 is a cylindrical structure, the endoscope 60 is a circular tempered glass plate adapted to the axial end of the adapter tube 50, the endoscope 60 is connected to one axial end of the adapter tube 50, and the other axial end of the adapter tube 50 is a closed cylinder bottom structure.
[0030] Specifically, the closed bottom structure is a circular plate that matches the shape of the axial end of the transfer tube 50 and is integrally formed with the transfer tube 50 cylinder body, and the other end is connected to the endoscope 60 to form a closed cavity of the transfer tube 50. The operator can observe the flow size of the separated water inside the transfer tube 50 through the end where the endoscope 60 is located.
[0031] In this embodiment, by setting the transfer tube 50 as a cylindrical structure, when the first pipeline 10 is connected to the side of its tube wall, the separated water can more easily flow to the lower part of the transfer tube 50 and then flow into the second pipeline 20. Of course, under normal circumstances, the axis of the transfer tube 50 is parallel to the horizontal plane, which is more convenient for observation. By setting the endoscope 60 as a circular tempered glass plate that matches the axial end of the transfer tube 50, on the one hand, it is convenient for operators to observe, and on the other hand, it is convenient to connect with the end of the transfer tube 50, and the structure is more stable. By setting the other end of the transfer tube 50 as a closed cylinder bottom structure, the whole is a closed cavity structure with a stable structure, which can prevent overflow and volatilization and is safer and more reliable to use.
[0032] Alternatively, if Figure 1As shown, the adapter tube 50 is a circular tubular structure, and the peepscope 60 is a circular tempered glass plate adapted to the axial end of the adapter tube 50 . The two peepscopes 60 are respectively connected to the axial ends of the adapter tube 50 .
[0033] Specifically, the axis of the transfer tube 50 is parallel to the horizontal plane, and thus, the observation results of the operator at both ends of the transfer tube 50 are the same.
[0034] In this embodiment, by setting the adapter tube 50 as a circular tubular structure, the beneficial effects are similar to those of the above-mentioned cylindrical structure and are not repeated here. In addition, by respectively connecting two endoscopes 60 to the axial ends of the adapter tube 50, the operator can observe from the axial ends of the adapter tube 50 respectively, thereby further facilitating the operation.
[0035] Optionally, the crude benzene dehydration device further includes a pressing ring 70 , the pressing ring 70 is adapted to the shape of the axial end of the transfer tube 50 , and the sight glass 60 is crimped to the axial end of the transfer tube 50 through the pressing ring 70 .
[0036] Specifically, the endoscope 60 is a circular tempered glass plate, the pressure ring 70 is a circular ring structure, the diameter of the endoscope 60 is slightly smaller than the outer diameter of the pressure ring 70, and the outer diameter of the pressure ring 70 is the same as the outer diameter of the adapter tube 50, so the structure is more regular and easy to install.
[0037] In this embodiment, by providing a pressure ring 70 and crimping the end of the endoscope 60 to the axial end of the adapter tube 50 through the pressure ring 70, installation is convenient, the endoscope 60 is not easily damaged, and the structure is more stable and reliable.
[0038] Alternatively, if Figure 1 As shown, the crude benzene dehydration device also includes a sealing gasket, which is connected between the sight glass 60 and the axial end of the transfer tube 50, and the pressure ring 70 is detachably connected to the axial end of the transfer tube 50.
[0039] Specifically, the sealing gasket is a polytetrafluoroethylene gasket. At the same time, the axial ends of the pressure ring 70 and the adapter tube 50 are respectively provided with axial connecting holes. The pressure ring 70 and the adapter tube 50 can be detachably connected by, for example, bolts, and the endoscope 60 and the sealing gasket are crimped between the two.
[0040] In this embodiment, a sealing gasket is provided between the endoscope 60 and the adapter tube 50, so that the sealing performance is further improved to prevent leakage or volatilization, and the structure is more reliable and safe. At the same time, by detachably connecting the pressure ring 70 to the adapter tube 50, connection and disassembly are facilitated, that is, replacement of the endoscope 60 is facilitated, and it is more convenient to use.
[0041] Alternatively, if Figure 1As shown, the crude benzene dehydration device further includes a third pipeline 30 and a third valve body 31 . The third pipeline 30 is connected to the upper part of the pipe wall of the transfer tube 50 , and the third valve body 31 is arranged on the third pipeline 30 .
[0042] It should be noted that when the crude benzene dehydration operation is being carried out, there may be air or other gases in the pipeline that disrupt the flow of water separated from the crude benzene, especially in the cavity of the transfer tube 50, where airflow is likely to disrupt the water flow. Therefore, by connecting the third pipeline 30 at the upper part of the pipe wall of the transfer tube 50, regular exhaust can be performed to avoid the above-mentioned situation and affect the operation efficiency and effect.
[0043] In this embodiment, by connecting the third pipeline 30 at the upper part of the pipe wall of the transfer tube 50 and disposing a third valve body 31 on the third pipeline 30, the on-off of the third pipeline 30 can be regulated by the third valve body 31, and then, the transfer tube 50 can be vented regularly or irregularly, so that the crude benzene dehydration operation is smoother and the operation efficiency is further improved.
[0044] Alternatively, if Figure 1 As shown, a cover plate 32 is provided at one end of the third pipeline 30 away from the transfer tube 50 .
[0045] Specifically, the shape of the cover plate 32 is compatible with the shape of the port of the third pipeline 50, and can be connected thereto by hinged or buckled connection, etc., as long as it is convenient to open and close, and no specific limitation is made here.
[0046] In this embodiment, a cover plate 32 is provided at one end of the third pipeline 30 away from the transfer tube 50, that is, the upper end. When the third pipeline 30 is not used for exhaust, the cover plate 32 can be covered on the upper end port of the third pipeline 30 to prevent foreign matter or rainwater from entering the third pipeline 30, that is, to prevent them from entering the transfer tube 50 and affecting the operation quality. Of course, when exhaust is performed through the third pipeline 30, the cover plate 32 can be removed for easy use.
[0047] Alternatively, if Figure 1 As shown, the crude benzene dehydration device further includes a fourth pipeline 40 and a fourth valve body 41 . The fourth pipeline 40 is in communication with the second pipeline 20 , and the fourth valve body 41 is disposed on the fourth pipeline 40 .
[0048] It should be noted that during the crude benzene dehydration operation, operators not only need to visually observe the water flow size, but sometimes also need to sample and test the crude benzene separation water to judge product quality or operation progress, etc. Therefore, by connecting the fourth pipeline 40 to the second pipeline 20, it can be used as a sampling port to facilitate sampling and testing.
[0049] In this embodiment, the fourth pipeline 40 is connected to the second pipeline 20, and a fourth valve body 41 is provided on the fourth pipeline 40. The fourth valve body 41 can regulate the on-off of the fourth pipeline 40. When it is necessary to sample and test the crude benzene separated water, the fourth valve body 41 can be opened, and the crude benzene separated water can flow out from the fourth pipeline 40 as a sample for testing. It is easy to use and convenient for testing.
[0050] Alternatively, if Figure 1 As shown, the crude benzene dehydration device further includes a first valve body 11 and a second valve body 21 . The first valve body 11 is disposed in the first pipeline 10 , and the second valve body 21 is disposed in the second pipeline 20 .
[0051] Specifically, the first valve body 11 and the second valve body 21 may be manually controlled valves or electromagnetically controlled valves, that is, when in use, the first pipeline 10 and the second pipeline 20 may be opened and closed by manual regulation or electrical control.
[0052] In this embodiment, by respectively arranging the first valve body 11 and the second valve body 21 on the first pipeline 10 and the second pipeline 20, the first valve body 11 and the second valve body 21 can respectively regulate the on-off of the first pipeline 10 and the second pipeline 20, that is, the start and stop of the crude benzene dehydration operation can be regulated at any time, which is convenient to use and improves the operation efficiency.
[0053] In addition, another embodiment of the utility model provides a processing equipment, including the crude benzene dehydration device as described above.
[0054] Exemplarily, the processing equipment is equipment for processing crude benzene or benzene, including a crude benzene storage tank 01 and a venting tank 02. Of course, the processing equipment may also be other, which is not specifically limited here.
[0055] In this embodiment, the processing equipment described in this embodiment is provided with the above-mentioned crude benzene dehydration device, and its technical effect is substantially the same as the technical effect of the above-mentioned crude benzene dehydration device, which will not be repeated here.
[0056] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto.
