Description

TECHNICAL FIELD

[0001] The utility model relates to the field of chemical equipment, concretely relates to a liquid collecting device. BACKGROUND

[0002] In the field of chemical production, in the preheating process of non-continuous operation heater, the safety pressure in the heater needs to be kept, so part of liquid needs to be discharged to achieve pressure balance. The collecting barrels used for collecting the liquid discharged from the heater in the prior art are mostly open structure, the liquid in the collecting barrel is easy to volatilize to the outside, so it is still necessary to improve the environment outside the collecting barrel by exhaust auxiliary.

[0003] Chinese patent CN205127650U discloses a kind of exhaust treatment system with gas-liquid separation structure, including solution recovery barrel, exhaust duct is connected on solution recovery barrel, waste gas is guided to place to discharge by the exhaust duct, can avoid waste gas to be polluted around recovery barrel environment.

[0004] However, in the above scheme, special gas-liquid separation device needs to be set on solution recovery barrel, and exhaust device is communicated on exhaust duct, which leads to more complex overall structure. UTILITY MODEL CONTENT

[0005] Therefore, the utility model provides a kind of liquid collecting device to solve the defects that the equipment overall structure of volatile gas after treatment of liquid collecting device of existing liquid is complex.

[0006] The utility model provides a kind of liquid collecting device, including collecting barrel, joint, condensing pipeline and waste gas recovery pipeline, the top of the collecting barrel is provided with liquid inlet;The joint is sealingly connected on the liquid inlet, and the joint is provided with liquid inlet passage and gas outlet passage;One end of the condensing pipeline is used for being communicated with the liquid source to be collected, and the other end is communicated with the liquid inlet passage;One end of the waste gas recovery pipeline is communicated with the gas outlet passage, and the other end is used to extend to waste gas treatment area.

[0007] The device can realize the collection of liquid and the reasonable discharge and subsequent treatment of waste gas by sealing the joint on the liquid inlet of the collection barrel, opening the liquid inlet channel and the gas outlet channel on the joint, and cooperating with the condensing pipeline and the waste gas recovery pipeline. It is not necessary to set a special gas-liquid separation device, nor to set a gas extraction device on the waste gas recovery pipeline. In this way, the overall structure is greatly simplified, the setting of additional equipment is reduced, and the complexity and manufacturing cost of the device are reduced. At the same time, the device can effectively treat waste gas. By sealing the joint on the liquid inlet of the collection barrel, the sealing of the entire device during operation is ensured. This not only prevents the leakage of liquid and waste gas, but also allows the waste gas in the collection barrel to be smoothly discharged into the waste gas treatment area through the predetermined gas outlet channel and the waste gas recovery pipeline, thereby avoiding pollution caused by direct discharge of waste gas into the surrounding environment of the collection barrel.

[0008] Optionally, the gas outlet channel comprises an annular segment arranged around the liquid inlet channel in the joint, and further comprises an extension segment extending from the side wall of the joint towards the annular segment.

[0009] By dividing the gas outlet channel into an annular segment and an extension segment, the space structure inside the joint can be fully utilized, and the waste gas collection efficiency can be improved. The annular segment around the liquid inlet channel allows the gas escaping from the collection barrel to enter the annular gas outlet channel area naturally and orderly. The annular structure can uniformly collect the gas volatilized from different directions of the collection barrel, ensuring the comprehensive collection of volatilized waste gas. The extension segment extending from the side wall of the joint to the annular segment provides a path for the waste gas to enter the annular segment from the side wall of the joint, facilitating the collection of volatilized waste gas in the collection barrel into the gas outlet channel. This structural design closely connects the gas outlet channel and the joint, and the layout is compact and reasonable, which helps to solve the problem of complex overall structure of the existing liquid collection device when treating volatilized gas.

[0010] Optionally, an external member is detachably connected to the extension segment, and the waste gas recovery pipeline is connected to the external member.

[0011] By providing a detachable external member on the extension segment, the flexibility and adaptability are enhanced when the liquid collection device faces different use scenarios, various specifications of waste gas recovery pipelines, or different layout requirements of waste gas treatment areas. As a key intermediate component connecting the extension segment and the waste gas recovery pipeline, the external member can smoothly and orderly guide the gas flowing out of the gas outlet channel of the joint into the waste gas recovery pipeline, and then transport it to the waste gas treatment area, making the gas recovery path more reasonable and clear. The close cooperation of each component ensures the continuity of the volatilized gas collection and treatment process of the device. Moreover, the detachable connection design has obvious advantages in pipeline inspection, maintenance or replacement, and the staff can operate quickly and efficiently, making maintenance more convenient.

[0012] Optionally, the liquid inlet channel extends vertically, and the lower end of the condensing pipe extends vertically to the inside of the collection barrel.

[0013] By vertically extending the liquid inlet channel, the liquid to be treated can naturally fall into the collection barrel by gravity, reducing flow resistance and enabling rapid and stable entry into the collection barrel, thereby effectively improving the collection efficiency of the liquid collection device. When the liquid flows into the barrel along the condensing pipe, the liquid can better contact the low-temperature environment in the barrel due to the deep insertion of the pipe, which is beneficial to the early condensation of volatile components and reduces the amount of waste gas formed by subsequent volatilization, thereby indirectly reducing the processing capacity of the waste gas recovery pipe and alleviating the subsequent waste gas treatment pressure. This makes the device better handle the gas volatilized after liquid collection, avoiding pollution of the external environment. In addition, the vertically extending design realizes the functions of liquid collection and gas treatment without adding complex turning and guiding components, making the liquid collection device relatively simple and compact, and effectively addressing the structural complexity of existing devices in treating liquid volatilized gas.

[0014] Optionally, the lower end of the condensing pipe extends vertically to the upper 1 / 3 position inside the collection barrel.

[0015] By setting the lower end of the condensing pipe at the upper 1 / 3 position inside the collection barrel, the liquid flowing from the source of liquid to be collected can have an appropriate landing height when entering the collection barrel. This way, it neither splashes severely due to a too high landing point, affecting the stable collection and subsequent storage stability of the liquid in the collection barrel, nor directly impacts the bottom of the barrel due to a too low landing point, causing excessive stress on the bottom. In this way, the liquid can be relatively stable and orderly collected in the collection barrel. Moreover, when the liquid enters from this specific position, it transfers less heat to the upper space in the collection barrel, which is better than the case where the lower end of the condensing pipe extends to a deeper position in the collection barrel, thereby reducing the heating effect on the gas in the upper part of the collection barrel.

[0016] Optionally, the joint has an insertion section inserted towards the liquid inlet, and the root of the insertion section has a protruding boss in the circumferential direction, and the lower surface of the boss is sealingly arranged around the liquid inlet.

[0017] The connecting structure sealed by the insertion section and the boss not only enables the gas to smoothly enter the waste gas recovery pipeline, but also effectively processes the volatilized gas while simplifying the overall structure, effectively making up for the deficiency of the existing liquid collection device in processing the volatilized gas, and significantly enhancing the sealing between the joint and the liquid inlet of the collection barrel, eliminating the possibility of gas leakage at the joint caused by the volatilization of the liquid in the collection barrel, ensuring that the gas that should be transported to the waste gas treatment area by the waste gas recovery pipeline will not escape into the surrounding environment, improving the reliability of the entire device in the gas processing link, and reducing the risk of pollution to the surrounding environment caused by gas leakage. In addition, the relatively simple and clear sealing connection structure of the joint and the liquid inlet is more convenient for operators to install, and operators only need to follow the established insertion section and boss sealing requirements to quickly and accurately complete the connection and assembly work of the joint and the liquid inlet of the collection barrel.

[0018] Optionally, a sealing gasket is arranged between the lower surface of the boss and the periphery of the liquid inlet.

[0019] The sealing gasket arranged between the joint and the liquid inlet of the collection barrel can build a more reliable sealing connection. In this way, during liquid collection, the liquid or volatilized gas in the collection barrel can be prevented from leaking from the connection between the joint and the liquid inlet, and the internal pressure environment of the liquid collection device can be maintained relatively stable. Liquid collection in chemical production has specific requirements for pressure, and good sealing can ensure that the pressure in the collection barrel is appropriate, so that the liquid inlet, gas outlet and other links can operate normally, prevent pressure imbalance caused by leakage, and affect the stable operation of the device. In addition, the sealing gasket can effectively block the leakage of liquid and gas, reducing the erosion of device components such as joints, collection barrels, etc. Chemical liquids are mostly corrosive, and after leakage, the contact components will be damaged and rusted after a long time, while the sealing gasket can reduce this risk, prolong the service life of the liquid collection device, and reduce the cost of replacing and maintaining the equipment of the enterprise.

[0020] Optionally, the joint and the liquid inlet of the collection barrel are connected by threads.

[0021] The threaded connection greatly simplifies the assembly and disassembly process of the joint and the liquid inlet of the collection barrel. Whether in the actual production stage of chemical products or in the scenarios of equipment installation, daily maintenance, periodic maintenance, etc., the staff only needs to rotate the joint to easily realize its connection or separation with the collection barrel, which is convenient and efficient to operate. Moreover, the threaded connection has good sealing effect after tightening. When the joint and the liquid inlet of the collection barrel are tightly screwed, the gap between them is significantly reduced, effectively reducing the risk of liquid or gas leakage from the connection, and effectively ensuring the sealing of the entire system, laying a solid foundation for the smooth operation of the device. Moreover, with the help of threaded connection, the joint can be firmly fixed on the liquid inlet of the collection barrel. Even if it is subjected to certain external force impact in the chemical production environment, the entire device is not prone to loosening and displacement, etc., which greatly improves the durability and reliability of the liquid collection device.

[0022] Optionally, the outer wall of the part of the joint exposed outside the collection barrel is a polygonal structure.

[0023] By designing the outer wall of the part of the joint exposed outside the collection barrel as a polygonal structure, when installing or dismounting the connection between the joint and the liquid inlet of the collection barrel, a tool such as a wrench that can catch the polygonal edge can be used to apply force, making the operation more convenient and stable. Unlike a circular outer wall that is easy to slip and difficult to force, a polygonal outer wall allows more precise control of the rotation force and direction, making the threaded connection or dismounting process between the joint and the liquid inlet smooth, and significantly improving the work efficiency during device assembly and maintenance. In addition, during the use of the device, the polygonal structure of the outer wall can better resist various external force disturbances that may occur from the outside, avoiding accidental situations such as joint loosening and rotation, and ensuring the stability of the entire liquid collection device structure.

[0024] Optionally, at least part of the section of the condensation pipeline and / or the waste gas recovery pipeline is a transparent body.

[0025] In chemical production, if part or all of the condensing pipeline is made of transparent material, the operator can directly observe the flow condition of the liquid in the pipeline, including the flow rate and whether there is blockage. The normal flow of the liquid is crucial to the entire collection process. Once the flow rate is too slow or stagnant, it may be that the pipeline is internally scaled, blocked by foreign matter, or the source of the liquid to be collected has a problem. With the transparent condensing pipeline, these abnormalities can be detected in a timely manner, so that maintenance measures can be taken quickly to ensure the smooth progress of the liquid collection work. Similarly, if the waste gas recovery pipeline is transparent, the operator can directly observe the flow condition of the waste gas in the pipeline to determine whether there is gas leakage and whether the gas flow is smooth. If the waste gas flow is found to be slow or the gas flow fluctuates abnormally, it may mean that the pipeline connection part is not well sealed or the pressure in the waste gas treatment area at the rear end is abnormal, so that the fault point can be checked in a timely manner to ensure that the waste gas is normally transported to the treatment area and prevent waste gas leakage from polluting the surrounding environment.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0032] In the field of chemical production, the collection barrels 1 used for collecting the liquid discharged from the heater are mostly open structures, and the liquid in the collection barrels 1 is easy to evaporate (the evaporation is caused by the pressure reduction of the discharged liquid), and the waste gas formed by the evaporation is easy to diffuse to the external space, and needs to be recovered and treated. In the existing exhaust treatment system with gas-liquid separation structure, a special gas-liquid separation device needs to be arranged on the solution recovery barrel to perform gas-liquid separation operation, and an exhaust gas recovery device needs to be connected to the exhaust pipeline to recover the waste gas, which leads to a relatively complex structure of the entire exhaust treatment system.

[0033] The embodiment provides a gas-liquid collection device for the complex overall structure of the existing exhaust treatment system with gas-liquid separation structure. By sealing the joint 3 on the liquid inlet 2 of the collection barrel 1, and opening the liquid inlet channel 4 and the gas outlet channel 5 on the joint 3, and then cooperating with the condensing pipeline 6 and the waste gas recovery pipeline 8, the collection of the liquid and the reasonable discharge and subsequent treatment of the waste gas can be realized. The embodiment not only simplifies the overall structure of the liquid collection device, but also ensures the effective recovery of the waste gas evaporated during the liquid collection process.

[0034] As shown in Figure 1 and Figure 2 , the liquid collection device provided by the embodiment mainly comprises a collection barrel 1, a joint 3, a condensing pipeline 6 and a waste gas recovery pipeline 8.

[0035] Specifically, the top of the collection barrel 1 is provided with a liquid inlet 2, and the joint 3 is connected to the liquid inlet 2 in a sealing manner. The joint 3 is provided with a liquid inlet channel 4 and a gas outlet channel 5. One end of the condensing pipeline 6 is connected to a liquid source 7 to be collected, and the other end is connected to the liquid inlet channel 4. One end of the waste gas recovery pipeline 8 is connected to the gas outlet channel 5, and the other end extends to a waste gas treatment area.

[0036] In the embodiment, the collecting barrel 1 is used as the main container of the whole liquid collecting device, and the top of the collecting barrel 1 is provided with a liquid inlet 2, and the liquid inlet 2 is designed to determine the position of the liquid inlet of the collecting barrel 1, and provide a channel for receiving the liquid to be collected from other sources; the joint 3 is sealingly connected to the liquid inlet 2, and plays a key role in connection and distribution, on the one hand, the joint 3 is provided with a liquid inlet channel 4, which can guide the liquid to be collected from the condensing pipeline 6 into the collecting barrel 1, and ensure the continuity of the liquid collecting path, on the other hand, the joint 3 is also provided with a gas outlet channel 5, which takes into account that the liquid collected in the collecting barrel 1 will generate waste gas after being introduced into the collecting barrel 1, and the pressure in the condensing pipeline 6 is larger than the pressure in the barrel, so the pressure of the liquid to be collected will decrease during the process of being introduced into the collecting barrel 1, and some liquid will volatilize to generate waste gas, but the pressure of the liquid flowing into the collecting barrel 1 and the waste gas generated in the barrel is larger than the pressure in the waste gas recovery pipeline 8, so the waste gas generated by volatilization will flow into the waste gas treatment area through the gas outlet channel 5, and the sealing connection between the joint 3 and the liquid inlet 2 can ensure the sealing of the whole device to a certain extent, and prevent the waste gas from leaking into the external environment.

[0037] Specifically, the liquid collecting device of the utility model does not need to be provided with a special gas-liquid separation device, and does not need to be additionally connected to an air extraction device on the exhaust pipeline, and only relies on the collecting barrel 1, the joint 3, the condensing pipeline 6 and the waste gas recovery pipeline 8, and through reasonable connection and function design, the functions of liquid collection and waste gas treatment are realized, the overall structure is greatly simplified, the complexity and manufacturing cost of the device are reduced, at the same time, the liquid inlet 2 of the collecting barrel 1, the liquid inlet channel 4 of the joint 3 and the condensing pipeline 6 form a stable liquid conveying path, which can make the liquid to be collected flow smoothly into the collecting barrel 1 for collection and storage, and the sealing connection of the joint 3 and other designs can also avoid leakage and other abnormal situations during the liquid inflow process, and ensure the reliability and stability of the whole liquid collecting process, and meet the normal needs of liquid collection operation in chemical production. And through the cooperation of the gas outlet channel 5 of the joint 3 and the waste gas recovery pipeline 8, the waste gas generated by the volatilization of the liquid in the collecting barrel 1 can be guided to the waste gas treatment area 9 in time and effectively, which prevents the waste gas from being directly discharged into the surrounding environment to cause pollution, and ensures that the air quality of the chemical production area can meet the environmental protection requirements.

[0038] In other embodiments, the joint 3 and the liquid inlet 2 of the collection barrel 1 can be connected through a plug-in sealing connection. The liquid inlet 2 of the collection barrel 1 is made into a cylindrical shape slightly smaller than the outer diameter of the joint 3. A layer of sealing lubricating grease is applied to the inner wall of the liquid inlet 2 and the outer wall of the joint 3. The joint 3 can be directly inserted into the liquid inlet 2, relying on the tight fit of the joint and the sealing effect of the sealing lubricating grease to prevent liquid leakage. In addition, a ring-shaped protrusion can be provided on the part of the joint 3 that is inserted. When the joint 3 is fully inserted into the liquid inlet 2, the protrusion will abut against the inside edge of the liquid inlet 2, preventing the joint 3 from accidentally coming out. This connection method is simple and direct, and the cost is relatively low. That is, whether the joint 3 and the liquid inlet 2 of the collection barrel 1 are connected through a threaded connection or a plug-in sealing connection, they all belong to the protection scope of the present embodiment.

[0039] It should be noted that the present embodiment does not limit the specific structure of the gas outlet passage 5, the connection between the gas outlet passage 5 and the waste gas recovery pipeline 8, the connection layout of the liquid inlet passage 4 and the condensing pipeline 6 with the collection barrel 1, the specific position of the lower end of the condensing pipeline 6 inside the collection barrel 1, the specific structure of the joint 3, the sealing condition of the joint 3 and the liquid inlet 2, the specific sealing structure, the connection method between the joint 3 and the liquid inlet 2, and the structure of the part of the joint 3 that leaks out of the collection barrel 1. This is because these non-limited parts can be flexibly adjusted and designed according to actual chemical production needs, site conditions, cost budget, and the characteristics of the liquid and waste gas being processed. Different chemical production scenarios may have different requirements for the shape, size, and direction of the gas outlet passage 5, and the connection layout of the liquid inlet passage 4 and the condensing pipeline 6 with the collection barrel 1 may vary due to the size and shape of the collection barrel 1 and the spatial layout of the entire device to achieve optimal liquid transfer efficiency. The position of the lower end of the condensing pipeline 6 inside the collection barrel 1 may affect the liquid collection effect and the amount of waste gas generated, and needs to be accurately positioned according to the specific properties of the liquid and the collection target. The specific structure of the joint 3 can also be customized based on the convenience of connection, sealing requirements, and cost control. Whether a more complex joint 3 with multiple sealing structures is used or a simpler but reliable form is chosen, the decision can be made according to the actual situation within the framework of the present embodiment. In summary, this non-limiting nature gives the liquid collection device wide adaptability and scalability in different chemical application scenarios, enabling it to better meet diverse industrial production needs and further highlighting the flexibility and practicality of the device design.

[0040] The specific structure of the gas outlet passage 5 of the present embodiment will be described in detail below.

[0041] As Figure 1 and Figure 2As shown, in some embodiments, the air outlet channel 5 includes an annular segment 10 arranged around the liquid inlet channel 4 in the connector 3 , and also includes an extension segment 11 extending from the side wall of the connector 3 toward the annular segment 10 .

[0042] Specifically, by setting the air outlet channel 5 as two parts, namely the annular section 10 and the extension section 11, the spatial structure inside the joint 3 is fully utilized, wherein the annular section 10 is arranged around the liquid inlet channel 4, so that the gas volatilized from the collection barrel 1 can be quickly captured by the annular section 10. No matter from which direction the gas is generated around the liquid inlet channel 4, there is a greater probability that it will quickly enter the annular section 10, and then it can flow more smoothly to the subsequent waste gas recovery pipeline 8 through the extension section 11, which can more efficiently collect volatile gases, avoid the gas from partially escaping to the external environment after disorderly diffusion in the collection barrel 1, and improve the collection efficiency of the volatile gas of the entire device. At the same time, by designing such an annular section 10 surrounding the liquid inlet channel 4 and the extension section 11 matched therewith inside the connector 3, there is no need to set up a complex and space-consuming gas outlet structure in the collection barrel 1 or other parts. The gas outlet channel 5 is cleverly integrated into the connector 3, which is an existing component used to connect the liquid inlet, so that the structure of the entire liquid collection device is more compact, avoiding the situation in the prior art where a special gas-liquid separation device is set up and the exhaust duct is connected to the exhaust device, which leads to a complicated overall structure. This is in good agreement with the problem of complex overall structure of the equipment to be solved by the present invention, and while ensuring the effective discharge and collection of gas, the simplicity and compactness of the overall structure of the device are maintained. In addition, the extension section 11 extends from the side wall of the joint 3 to the annular section 10. This structure provides a stable path for the discharge of gas, allowing the gas to flow in an orderly manner from the collection barrel 1 through the gas outlet channel 5 to the waste gas recovery pipe 8 according to a predetermined channel, reducing turbulence in the gas flow or blockage caused by unreasonable channels, ensuring that the volatile gas can be stably and continuously transported to the waste gas treatment area 9 for subsequent treatment, further improving the reliability and stability of the entire liquid collection device in treating volatile gases.

[0043] The connection between the extension section 11 and the exhaust gas recovery pipe 8 of this embodiment is described in detail below.

[0044] like Figure 1 and Figure 2 As shown, in some embodiments, an external component 12 is detachably connected to the extension section 11 , and the exhaust gas recovery pipe is connected to the external component 12 .

[0045] Specifically, in the present embodiment, the connection of the exhaust gas recovery pipeline 8 is not in a fixed and unchangeable manner, but is achieved by means of a detachable external member 12, which is connected to the extension section 11 and ultimately to the exhaust gas recovery pipeline 8. This detachable connection provides great convenience in actual device installation, maintenance, and subsequent possible component replacement operations. At the same time, as the key intermediate component connecting the extension section 11 and the exhaust gas recovery pipeline 8, the external member 12 enables the gas from the outlet channel 5 of the joint 3 to be smoothly and orderly introduced into the exhaust gas recovery pipeline 8 and then transported to the exhaust gas treatment area 9, which also makes the construction of the entire gas recovery path more reasonable and clear, with each component working in close coordination to ensure the continuity of the device's volatile gas collection and treatment process. In addition, the detachable connection design has significant advantages in maintenance. When the pipeline needs to be inspected, repaired, or replaced, workers can quickly and efficiently complete the corresponding operations by means of this detachable connection.

[0046] The connection layout of the liquid inlet channel 4 and the condensation pipeline 6 to the collection bucket 1 in the present embodiment is described in detail below.

[0047] As shown in Figs. Figure 1 and Figure 2 In some embodiments, the liquid inlet channel 4 extends vertically, and the lower end of the condensation pipeline 6 extends vertically into the interior of the collection bucket 1.

[0048] The vertical extension design of the liquid inlet channel 4 ensures that the liquid to be treated can naturally fall into the collection bucket 1 by gravity, reducing flow resistance and enabling the liquid to quickly and stably enter the collection bucket 1, thereby improving the efficiency of the entire liquid collection device in collecting liquid. At the same time, when the liquid flows into the collection bucket 1 along the condensation pipeline 6, the condensation pipeline 6 extends deep into the bucket, allowing the liquid to better contact the relatively low-temperature environment inside the collection bucket 1 during this process, which is conducive to the early condensation of volatile components in the liquid, reducing the amount of waste gas formed in the upper space of the collection bucket 1. In this way, the amount of waste gas that needs to be treated through the exhaust gas recovery pipeline 8 is reduced to some extent from the source, indirectly reducing the pressure on subsequent waste gas treatment, which helps the entire device to more efficiently deal with the problem of gas volatilization after liquid collection and avoid adverse effects on the external environment. In addition, this vertical extension design, while ensuring the implementation of liquid collection and subsequent gas treatment functions, does not introduce additional complex turning or guiding structural components, making the overall structure of the entire liquid collection device relatively simple and compact, but also effectively addressing the complexity of the overall structure of existing liquid collection devices in treating the gas volatilized after liquid collection.

[0049] The specific position of the lower end of the condensation pipeline 6 inside the collection bucket 1 in the present embodiment is described in detail below.

[0050] As Figure 1 and Figure 2 shown, in some embodiments, the lower end of the condensing pipeline 6 extends vertically to a position 1 / 3 of the upper region of the collection barrel 1.

[0051] In the present embodiment, it can be understood by those skilled in the art that the setting of the lower end of the condensing pipeline 6 at a position 1 / 3 of the upper region of the collection barrel 1 can ensure that the liquid flowing out of the liquid source 7 to be collected has a suitable drop height when entering the collection barrel 1. This position can not only avoid the situation that the liquid splashes too severely due to too high a drop point, affecting the stable collection of the liquid in the collection barrel 1 and the subsequent storage stability, etc., but also prevent the liquid from directly impacting the bottom of the collection barrel 1 due to too low a drop point, which may cause the bottom of the collection barrel 1 to be partially stressed too much, etc., and help the liquid to be more stably and orderly collected in the collection barrel 1. At the same time, when the liquid enters the collection barrel 1 from this specific position, the heat carried by the liquid is transferred to the relatively limited upper space in the collection barrel 1, which is more conducive to reducing the heating effect on the gas in the upper space of the collection barrel 1 compared to the case where the lower end of the condensing pipeline 6 extends to a deeper position of the collection barrel 1.

[0052] Specifically, the gas volatilized during the liquid collection process in the collection barrel 1 needs to be guided to the waste gas treatment area 9 through the gas outlet passage 5 and the waste gas recovery pipeline 8. If the liquid enters and excessively heats the gas above, the flowability and volatility of the gas may change, which may make it more difficult for the gas to be smoothly discharged, and even may cause some gas to accumulate in the collection barrel 1 and not be discharged in time and effectively through the waste gas recovery pipeline 8, affecting the efficiency and effect of the entire device on gas treatment.

[0053] The specific structure of the joint 3 of the present embodiment will be described in detail below.

[0054] As Figure 1 and Figure 2 shown, in some embodiments, the joint 3 has an insertion section 13 inserted into the liquid inlet 2, and the root of the insertion section 13 has a protruding boss 14 in the circumferential direction, and the lower surface of the boss 14 is sealingly arranged around the liquid inlet 2.

[0055] Specifically, the connection structure sealed by the insertion section 13 and the boss 14 can ensure that the gas enters the waste gas recovery pipeline 8 smoothly, thereby simplifying the overall structure and effectively treating the emitted gas, and thus solving the defect of the complex overall structure of the existing liquid collecting device in treating the emitted gas after collecting the liquid. Moreover, the lower surface of the boss 14 and the surrounding of the liquid inlet 2 are sealed, which greatly enhances the sealing between the joint 3 and the liquid inlet 2 of the collecting barrel 1, effectively avoids the leakage of the gas emitted by the liquid in the collecting barrel 1 at the joint 3, prevents the gas that should be transported to the waste gas treatment area 9 through the waste gas recovery pipeline 8 from escaping into the surrounding environment, and thus improves the reliability of the gas treatment link of the entire device and reduces the pollution risk of the surrounding environment caused by the leakage of the gas. In addition, the relatively simple and clear sealing connection structure of the joint 3 and the liquid inlet 2 is easier for the operator to install, and the joint 3 and the liquid inlet 2 can be quickly and accurately connected and assembled according to the sealing requirements of the insertion section 13 and the boss 14.

[0056] The specific sealing structure of the present embodiment will be described in detail below.

[0057] As shown in Figs. Figure 1 and Figure 2 In some embodiments, a sealing gasket 15 is arranged between the lower surface of the boss 14 and the surrounding of the liquid inlet 2.

[0058] Specifically, the sealing gasket 15 forms a more reliable sealing connection between the joint 3 and the liquid inlet 2 of the collecting barrel 1, which prevents the liquid in the collecting barrel 1 or the gas emitted during the liquid collection process from leaking out of the connection part of the joint 3 and the liquid inlet 2. At the same time, the reliable sealing can ensure that the pressure environment inside the entire liquid collecting device is relatively stable. For the liquid collection involved in chemical production, there is a certain requirement for pressure, and good sealing can maintain the appropriate pressure state in the collecting barrel 1, ensure that each link such as liquid inlet and gas outlet operates normally as expected, and avoid problems such as pressure imbalance caused by leakage affecting the stable operation of the device. In addition, since the sealing gasket 15 effectively prevents the leakage of the liquid and the gas, it also reduces the erosion of these substances to other parts of the device (such as the joint 3 and the collecting barrel 1 itself). Chemical liquids often have certain corrosiveness, and if they leak and contact the device parts, they may cause damage, rust, and other problems over a long period of time. The sealing effect of the sealing gasket 15 reduces this risk, thereby helping to prolong the service life of the entire liquid collecting device and reduce the cost and maintenance frequency of replacing equipment for enterprises.

[0059] In addition, in other embodiments, the sealing gasket 15 provided between the lower surface of the boss 14 and the periphery of the liquid inlet 2 can be replaced with a sealing rubber strip. The sealing rubber strip can be made of a rubber material with good elasticity and sealing properties (such as nitrile rubber). Through its own elastic deformation, it tightly fills the gap between the lower surface of the boss 14 and the periphery of the liquid inlet 2, thereby performing a sealing function and preventing liquid from leaking from the connection portion. In other words, whether the sealing gasket 15 or the sealing rubber strip is provided between the lower surface of the boss 14 and the periphery of the liquid inlet 2, it falls within the scope of protection of this embodiment.

[0060] The connection between the connector 3 and the liquid inlet 2 of the collecting barrel 1 of this embodiment is described in detail below.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, the connector 3 is connected to the liquid inlet 2 of the collection barrel 1 via threads.

[0062] Specifically, in the structural design of the liquid collection device, the connector 3 has a corresponding threaded structure, and the liquid inlet 2 of the collection barrel 1 also has a matching thread. By screwing the threads together, the connector 3 can be firmly and tightly mounted on the liquid inlet 2 of the collection barrel 1. By adopting a threaded connection method, the assembly and disassembly process of the connector 3 and the liquid inlet 2 of the collection barrel 1 becomes relatively simple. In actual production, installation, and subsequent equipment maintenance and overhaul scenarios, staff can easily complete the connection or separation operation with the collection barrel 1 by rotating the connector 3. At the same time, the threaded connection itself can provide a certain sealing effect after being tightened. When the connector 3 and the liquid inlet 2 of the collection barrel 1 are tightly screwed together through the threads, the gap between the two can be effectively reduced, reducing the possibility of liquid or gas leakage from the connection, helping to maintain the sealing of the entire system and ensuring the normal and stable operation of the device. Through the threaded connection, the connector 3 can be firmly fixed on the liquid inlet 2 of the collection barrel 1, so that the entire device is not prone to loosening or displacement during operation even if it is subjected to a certain external force, thereby improving the durability and reliability of the entire liquid collection device in the chemical production environment.

[0063] In addition, in other embodiments, the joint 3 and the liquid inlet 2 of the collection barrel 1 can be connected through a plug-in sealing connection. The liquid inlet 2 of the collection barrel 1 is made into a cylindrical shape slightly smaller than the outer diameter of the joint 3, and a layer of sealing lubricating grease is applied to the inner wall of the liquid inlet 2 and the outer wall of the joint 3. The joint 3 can be directly inserted into the liquid inlet 2, relying on the tight fit at the joint and the sealing effect of the sealing lubricating grease to prevent liquid leakage. In addition, a ring-shaped protrusion can be provided on the inserted part of the joint 3. When the joint 3 is completely inserted into the liquid inlet 2, the protrusion will abut against the inside edge of the liquid inlet 2 to prevent the joint 3 from accidentally coming out. This connection method is simple and direct, and the cost is relatively low. That is, whether the joint 3 and the liquid inlet 2 of the collection barrel 1 are connected through a threaded connection or a plug-in sealing connection, they all belong to the protection scope of the present embodiment.

[0064] The structure of the part of the joint 3 that protrudes out of the collection barrel 1 will be described in detail below.

[0065] As shown in Figure 1 and Figure 2 , in some embodiments, the outer wall of the part of the joint 3 that protrudes out of the collection barrel 1 is a polygonal structure.

[0066] Specifically, in the present embodiment, by setting the outer wall of the part of the joint 3 that protrudes out of the collection barrel 1 as a polygonal structure, when connecting or disconnecting the joint 3 and the liquid inlet 2 of the collection barrel 1, a corresponding tool (such as a wrench that can hold the polygonal edge) can be used to apply force, making the operation more convenient and stable. Compared to the situation that a round outer wall may slip and be difficult to force, the polygonal structure can more accurately control the force and direction of rotation, thereby more smoothly completing the threaded connection or disconnection process between the joint 3 and the liquid inlet 2, effectively improving the work efficiency during device assembly and maintenance. At the same time, the polygonal structure of the outer wall can better resist various external force disturbances that may occur during device use, preventing the joint 3 from loosening, rotating, and other accidental situations, ensuring the stability of the entire liquid collection device structure.

[0067] The specific conditions of the condensation pipeline 6 and the waste gas recovery pipeline 8 of the present embodiment will be described in detail below.

[0068] As shown in Figure 1 and Figure 2 , in some embodiments, at least part of the condensation pipeline 6 and / or the waste gas recovery pipeline 8 is a transparent body 16.

[0069] Specifically, in this embodiment, when the condensation pipe 6 is partially or entirely transparent 16, operators can visually observe the flow of liquid within the pipe, such as the flow rate and whether there are any blockages. In chemical production, the normal flow of liquid is crucial to the entire collection process. If the flow rate is abnormally slow or stagnant, it may indicate scaling, blockage by foreign matter, or a supply problem with the source of collected liquid 7 at the front end. The transparent condensation pipe 6 allows these abnormalities to be promptly detected, allowing for rapid maintenance measures to ensure smooth liquid collection. Similarly, if the exhaust gas recovery pipe 8 is transparent 16, operators can observe the flow of exhaust gas within the pipe and determine whether there are any gas leaks or whether the airflow is smooth. If exhaust gas is observed to flow slowly or experience abnormal airflow fluctuations within the pipe, it may indicate a sealing problem at the pipe connection or abnormal pressure in the exhaust gas treatment area 9 at the rear end. This allows for timely troubleshooting to ensure that the exhaust gas is properly transported to the exhaust gas treatment area 9 and avoid pollution to the surrounding environment caused by exhaust gas leaks. In addition, the transparent condensation pipe 6 and exhaust gas recovery pipe 8 allow staff to quickly understand the operating status of these two key pipes without the help of additional complex detection tools. Moreover, when performing equipment maintenance, the transparent pipes also help maintenance personnel to more accurately locate the specific location of the problem, such as which section of the pipe is damaged or blocked, so that maintenance work can be carried out more efficiently, equipment downtime can be reduced, and the overall efficiency of chemical production can be improved.

[0070] In addition, in other embodiments, the transparent body 16 is made of Teflon, which has excellent chemical stability and can withstand corrosion from a variety of chemicals. During the chemical production process, Teflon pipes are not easily corroded, whether it is the liquid in the condensation pipe 6 (which may contain various chemicals such as acids and alkalis) or the exhaust gas components in the exhaust gas recovery pipe 8 (which may contain corrosive gases). This can ensure the service life of the pipe and reduce the risk of liquid leakage or exhaust gas leakage caused by pipe corrosion. As the transparent body 16, Teflon can provide good transparency, allowing operators to clearly observe the flow state of the liquid or exhaust gas inside the pipe. This helps to promptly detect problems such as abnormal flow rate, blockage, leakage, etc., and ensure the monitoring effect of the production process. In other words, whether it is a transparent body 16 made of Teflon or a transparent body 16 made of non-Teflon material, it falls within the scope of protection of this embodiment.

[0071] like Figure 1 and Figure 2 As shown, the working process of the liquid collecting device of this embodiment is as follows:

[0072] 1. Liquid collection process: The liquid to be collected passes through the condensing pipeline 6, and due to the vertical extension of the lower end of the condensing pipeline 6 to the inside of the collection barrel 1 (preferably extending to the upper 1 / 3 position of the inside of the collection barrel 1), the liquid naturally falls into the collection barrel 1 along the vertically extending liquid inlet channel 4 by gravity. In this process, the liquid can better contact the relatively low-temperature environment in the collection barrel 1, which is beneficial to the early condensation of volatile components in the liquid, reduces the amount of waste gas formed by subsequent volatilization, improves the liquid collection efficiency, and at the same time ensures that the liquid is relatively stable and orderly collected in the collection barrel 1.

[0073] 2. Waste gas collection and discharge process: The waste gas volatilized in the collection barrel 1 will escape through the gas outlet channel 5 in the joint 3, which is composed of an annular section 10 arranged around the liquid inlet channel 4 and an extension section 11 extending from the side wall of the joint 3 towards the annular section 10. The annular section 10 can uniformly collect volatile gas from different directions, and the extension section 11 facilitates the convergence of waste gas into the gas outlet channel 5, and the combination of the two can efficiently and comprehensively collect waste gas.

[0074] 3. Waste gas discharge and subsequent treatment process: The extension section 11 is detachably connected to the external component 12, and the waste gas recovery pipeline 8 is connected to the external component 12, so that the waste gas can be orderly introduced into the waste gas recovery pipeline 8 from the gas outlet channel 5, and finally extended to the waste gas treatment area 9 for treatment, avoiding direct discharge of waste gas to the surrounding environment causing pollution.

[0075] 4. Sealing protection and operation state monitoring process of the liquid collection device: The joint 3 is sealingly connected to the liquid inlet 2 of the collection barrel 1 through the insertion section 13 and the root circumferentially protruding boss 14, and the lower surface of the boss 14 and the surrounding of the liquid inlet 2 can be provided with a sealing gasket 15 to further enhance the sealing performance. At the same time, the joint 3 and the liquid inlet 2 of the collection barrel 1 are connected by threads, and the part of the outer wall of the joint 3 exposed outside the collection barrel 1 is designed as a polygonal structure to facilitate operation with tools. Through these structures, the overall sealing performance of the device is ensured to be good, which not only prevents liquid and waste gas from leaking, maintains the appropriate pressure state inside the device, and ensures the normal progress of liquid inlet, gas outlet and other links, but also improves the reliability of the device in the gas treatment link, reduces the pollution risk to the surrounding environment, and enhances the durability and reliability of the device in the chemical production environment. At least part of the condensing pipeline 6 and / or the waste gas recovery pipeline 8 is provided as a transparent body 16, so that the operating personnel can directly observe the flow state of the liquid or waste gas in the pipeline, and timely discover abnormal conditions such as abnormal flow rate, blockage, gas leakage, etc., so as to quickly locate the fault point, take appropriate maintenance measures, ensure the smooth progress of liquid collection and waste gas transportation, reduce equipment downtime, and improve the overall efficiency of chemical production.

[0076] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
