Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of gas-liquid separators, and more specifically, to a gas-liquid separator for chlorinated paraffin production. Background Art

[0002] In the production process of chlorinated paraffin, the treatment of tail gas is a key link. The chlorination reaction generates tail gas hydrogen chloride and chlorine, and the gas blown out by the blowing in the refining kettle also contains trace amounts of hydrogen chloride and chlorine. In order to effectively remove these harmful gases, equipment such as a three-stage hydrochloric acid falling film absorption tower, a tail gas absorption tower, and a spray tower are usually used to absorb the tail gas. During these absorption processes, the gas is in full contact with the absorption liquid. Although it can effectively absorb the harmful components in the tail gas, it also inevitably mixes moisture into the tail gas.

[0003] In order to ensure that the subsequent treatment process and the tail gas emission meet the environmental protection standards, before the tail gas is discharged from the system, a gas-liquid separator must be used to separate the gas and the liquid to ensure that the discharged tail gas carries as little liquid as possible, thereby improving the tail gas treatment effect. Currently, the filter-type gas-liquid separators widely used in the treatment of chlorinated paraffin production tail gas mostly adopt an integral filter plate structure. The tail gas carrying moisture is filtered through the filter plate, and the gas passes through the filter plate and is discharged, while the liquid is intercepted on one side of the filter plate, thereby realizing gas-liquid separation.

[0004] However, in the actual production process, since the tail gas may contain various impurities, the filter plate is prone to blockage after long-term use. After the filter plate is blocked or damaged, the entire filter plate needs to be replaced. However, on the one hand, the operation of replacing the entire filter plate is difficult; on the other hand, the cost of replacing the entire filter plate is high.

[0005] In summary, the existing filter-type gas-liquid separator with an integral filter plate structure is difficult to meet the requirements of chlorinated paraffin production for tail gas treatment. Therefore, it is urgent to develop a new type of gas-liquid separator structure. Summary of the Invention

The drainage channel, the overflow port, the drain port, and the drain pipe are sequentially communicated for discharging the liquid inside the filter cartridge. The height of the overflow port is higher than that of the drainage channel.

[0012] For example, in a gas-liquid separator for chlorinated paraffin production provided by at least one embodiment of the present disclosure, it further includes: A centrifugal impeller is rotatably arranged in the air inlet pipe, and the centrifugal impeller is used to throw out the liquid droplets in the gas towards the outer circumference direction.

[0013] For example, in a gas-liquid separator for chlorinated paraffin production provided by at least one embodiment of the present disclosure, it further includes: The side wall of the air inlet pipe has an opening, a cover plate is hinged at the opening, the cover plate is used to block the opening, and an elastic water-absorbing layer is arranged on the inner wall of the cover plate, and the elastic water-absorbing layer is used to absorb the liquid droplets thrown out by the centrifugal impeller.

[0022] The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the present disclosure, rather than limiting the present disclosure.

In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0024] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0027] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0028] Such as Figures 1 to 9As shown, in this embodiment, aiming at the drawbacks of the integral filter plate structure of the gas-liquid separator used in the existing chlorinated paraffin production, a gas-liquid separator in the form of a filter cartridge 2 is designed to improve the maintenance convenience of the equipment and reduce the maintenance cost.

[0029] The housing 1 is made of a corrosion-resistant metal material, such as stainless steel, to adapt to the chemical characteristics of the tail gas in chlorinated paraffin production. Its shape is generally cylindrical, with both ends closed. An inlet pipe 101, an outlet pipe 102, and a drain pipe 103 are respectively arranged on the side. A plurality of mounting holes 104 are evenly distributed on the end face of the housing 1, and the diameter of the mounting holes 104 matches the outer diameter of the filter cartridge 2. The filter cartridge 2 is integrally cylindrical. One end of the filter cartridge 2 is communicated with the inlet pipe 101, and the other end is a closed end. The wall of the filter cartridge 2 has filtering holes that can intercept liquids and allow gases to pass through. The closure 3 is circular and has a size larger than the diameter of the mounting hole 104 to cover the mounting hole 104 and achieve sealing. Bolt holes for connecting with the housing 1 are provided on the closure 3, and the closure 3 is fastened to the housing 1 through bolts, thereby plugging the mounting hole 104 and positioning the filter cartridge 2 at the same time.

[0030] When the tail gas carrying moisture in the chlorinated paraffin production process enters the gas-liquid separator from the inlet pipe 101, the tail gas enters the filter cartridge 2 connected to the inlet pipe 101. The gas can pass through the filtering holes on the wall of the filter cartridge 2 under the action of pressure, enter the interior of the housing 1, and then be discharged from the outlet pipe 102 and enter the subsequent tail gas treatment process. The liquid is intercepted inside the filter cartridge 2 and finally flows to the drain pipe 103 and is discharged from the gas-liquid separator.

[0031] When a certain filter cartridge 2 becomes blocked or damaged and needs to be replaced, only the bolts on the corresponding closure 3 need to be removed, the closure 3 is taken off, and then the blocked or damaged filter cartridge 2 is pulled out from the mounting hole 104 and a new filter cartridge 2 is replaced. This replacement method is simple to operate and does not require complex disassembly of the entire gas-liquid separator, greatly improving the maintenance efficiency.

[0032] With the structure of multiple independent filter cartridges 2, each filter cartridge 2 has a corresponding mounting hole 104 and closure 3. In actual production, it can be quickly replaced without affecting the normal operation of other filter cartridges 2, and there is no need to stop production for a long time to replace the integral filter plate, reducing the maintenance workload. Compared with the integral filter plate, the cost of a single filter cartridge 2 is lower. When replacing the filter cartridge 2, only the damaged or blocked part needs to be replaced, reducing the maintenance cost.

[0033] In some examples, such as Figure 4 and Figure 5 As shown, in this embodiment, to solve the problem that the fouling on the inner wall of the filter cartridge 2 affects the gas-liquid separation effect, a receiving sleeve 4, a support rod 5, a spring piece 6, and a cleaning fiber 7 are arranged inside the filter cartridge 2 to achieve efficient cleaning of the inner wall of the filter cartridge 2.

[0034] Specifically, a receiving sleeve 4 is provided inside the filter cartridge 2, and its shape is a circular tube, and it is arranged coaxially with the filter cartridge 2. The function of the receiving sleeve 4 is to store the spring pieces 6 when the filter cartridge 2 does not need to be cleaned, so as to prevent the spring pieces 6 and the cleaning fibers 7 from occupying too much space inside the filter cartridge 2, and to prevent the cleaning fibers 7 from being contaminated by impurities in the exhaust gas. The support rod 5 is movably arranged inside the filter cartridge 2, and a plurality of spring pieces 6 are evenly arranged along the circumferential direction at the bottom end of the support rod 5. The spring pieces 6 are elastic and can shrink when squeezed by external force, and can return to their original state after the external force disappears. There are cleaning fibers 7 on the spring pieces 6, and the cleaning fibers 7 are soft in texture and have strong adsorption capacity. When the spring pieces 6 expand, the cleaning fibers 7 can unfold and contact with the inner wall of the filter cartridge 2, and then absorb and entrain dirt to achieve a cleaning effect.

[0035] When the filter cartridge 2 is working, the spring piece 6 is inserted into the accommodating sleeve 4, and the spring piece 6 and the cleaning fiber 7 are squeezed and contracted in the accommodating sleeve 4, which will not interfere with the normal separation process and avoid being contaminated by impurities in the exhaust gas. When it is necessary to clean the dirt on the inner wall of the filter cartridge 2, the support rod 5 moves to separate the spring piece 6 from the accommodating sleeve 4. After the spring piece 6 separates from the accommodating sleeve 4, it expands outward due to its own elastic force, driving the cleaning fiber 7 to contact the inner wall of the filter cartridge 2. The cleaning fiber 7 scrapes against the inner wall of the filter cartridge 2 as the support rod 5 moves, absorbs the dirt on the inner wall of the filter cartridge 2, and cleans it. A drainage hole can be opened on the side of the accommodating sleeve 4 to avoid water accumulation inside.

[0036] The inner wall of the filter cartridge 2 can be cleaned conveniently without disassembling the filter cartridge 2 for cleaning. The inner wall of the filter cartridge 2 can be cleaned when the gas-liquid separator is installed. When the filter cartridge 2 is working normally, the spring piece 6 and the cleaning fiber 7 are stored in the accommodating sleeve 4, and do not occupy the internal space of the filter cartridge 2. At the same time, the cleaning fiber 7 is prevented from contacting with impurities in the exhaust gas to prevent contamination.

[0037] In some examples, such as Figure 4 and Figure 5 As shown, in this embodiment, the support rod 5 is designed as a screw rod, and the cleaning box 8 is arranged on the outer wall of the housing 1. A threaded hole is opened on the top, and the threaded hole is precisely matched with the thread of the support rod 5 to ensure that the support rod 5 can smoothly rotate in the threaded hole and make axial displacement. The cleaning box 8 is extended out of the top of the support rod 5 and a hand wheel 9 is arranged to facilitate the operator to apply force.

[0038] When it is necessary to clean the scale on the inner wall of the filter cartridge 2, the operator holds the handwheel 9 and rotates it. Since the support rod 5 is threadedly connected to the threaded hole on the dirt cleaning box 8, the support rod 5 will move along the axial direction while rotating. As the support rod 5 moves, the dirt cleaning fiber 7 can scrape the inner wall of the filter cartridge 2 in a rotating and moving state, adsorbing and entraining the scale, so as to clean the scale more thoroughly. Finally, the support rod 5 drives the dirt cleaning fiber 7 to move into the dirt cleaning box 8, and the operator can open the dirt cleaning door 10 at the bottom of the dirt cleaning box 8 to clean the scale on the dirt cleaning fiber 7. The dirt cleaning box 8 provides a space for centralized collection of the dirt after cleaning, improving the convenience of the cleaning work.

[0039] In some examples, such as Figure 4 and Figure 5 shown, in this embodiment, for the problems of liquid discharge and gas leakage prevention in the gas-liquid separator, the housing 1 is designed to be inclined, and structures such as a flow guide plate 201 and an overflow plate 202 are arranged in the filter cartridge 2.

[0040] A certain angle is specially set between the housing 1 and the horizontal plane, aiming to enable the liquid intercepted in the filter cartridge 2 to flow by gravity. The end of the flow guide plate 201 arranged inside the filter cartridge 2 extends to be close to but not in contact with the inner wall of the filter cartridge 2, thereby forming a liquid discharge channel 2011 between the flow guide plate 201 and the inner wall of the filter cartridge 2. An overflow plate 202 is also arranged in the filter cartridge 2, and the overflow plate 202 is arranged at a position in the filter cartridge 2 close to the liquid discharge port 203. An overflow port 2021 is opened on the overflow plate 202, and its height is higher than that of the liquid discharge channel 2011. A liquid discharge port 203 is opened on the side wall of the filter cartridge 2 corresponding to the position of the overflow plate 202, and the liquid discharge port 203 is communicated with the liquid discharge pipe 103.

[0041] When the gas-liquid mixture enters the filter cartridge 2, the gas passes through the wall of the filter cartridge 2 and is discharged, while the liquid is intercepted in the filter cartridge 2. Since the housing 1 is inclined, the liquid in the filter cartridge 2 flows along the flow guide plate 201 towards the liquid discharge channel 2011 under the action of gravity. As the liquid continuously accumulates, the liquid level in the liquid discharge channel 2011 gradually rises. When the liquid level exceeds the height of the overflow port 2021, the liquid overflows through the overflow port 2021, then flows out from the liquid discharge port 203, and finally is discharged from the gas-liquid separator through the liquid discharge pipe 103.

[0042] Since the overflow port 2021 is higher than the liquid discharge channel 2011, a certain height of accumulated liquid will form at the overflow plate 202. This part of the accumulated liquid can block the outlet of the liquid discharge channel 2011, forming a liquid seal structure, so that the gas in the filter cartridge 2 cannot leak through the liquid discharge channel 2011 and the overflow port 2021, and can only be discharged normally from the wall of the filter cartridge 2, ensuring the tightness of the gas-liquid separation process. The inclined setting of the housing 1 utilizes the gravity effect to enable the liquid to flow and discharge in the filter cartridge 2, avoiding the influence of liquid accumulation on the gas-liquid separation effect. The liquid seal structure formed by the ingenious design of the overflow plate 202 and the overflow port 2021 prevents the gas from leaking through the liquid discharge channel 2011. This sealing method is formed naturally, without additional sealing devices, and has a simple structure and high reliability.

[0043] In some examples, such as Figure 6 and Figure 7 shown, in this embodiment, to further optimize the separation effect of the gas-liquid separator, a centrifugal impeller 11 and a supporting cover plate 1012 and elastic water-absorbing layer 12 structure are added at the inlet pipe 101 to achieve the preliminary separation of large liquid droplets in the gas, reduce the separation burden of the subsequent filter cartridge 2, and improve the overall gas-liquid separation efficiency.

[0044] The centrifugal impeller 11 is rotatably arranged inside the inlet pipe 101. The centrifugal impeller 11 is connected to an external driving element through a central shaft. The external driving element can be a motor or a pneumatic motor, etc., to provide rotational power for the centrifugal impeller 11. An opening 1011 is formed on the side wall of the inlet pipe 101. The cover plate 1012 is connected to the opening 1011 by a hinged manner. The hinge point is located on the side of the opening 1011, enabling the cover plate 1012 to rotate around the hinge point to block and open the opening 1011. The size of the cover plate 1012 is slightly larger than the opening 1011 to ensure complete coverage of the opening 1011. An elastic water-absorbing layer 12 is arranged on the inner wall of the cover plate 1012, preferably a sponge layer, which can absorb the liquid droplets thrown out by the centrifugal impeller 11.

[0045] When the gas containing moisture enters the inlet pipe 101, the external driving element drives the centrifugal impeller 11 to rotate at a high speed. The large liquid droplets in the gas are thrown out towards the outer circumference under the action of centrifugal force. These thrown large liquid droplets hit the elastic water-absorbing layer 12 on the inner wall of the cover plate 1012 and are absorbed by the elastic water-absorbing layer 12. After the gas is preliminarily separated from the large liquid droplets, it enters the filter cartridge 2 for more refined gas-liquid separation. When the elastic water-absorbing layer 12 needs to be replaced or maintained, the operator can open the cover plate 1012 to replace or clean and maintain the elastic water-absorbing layer 12, and then rotate the cover plate 1012 back to its original position to block the opening 1011 and continue the gas-liquid separation work.

[0046] The structural form of the filter cartridge 2 is more suitable for dealing with small droplets. In this embodiment, the centrifugal impeller 11 preliminarily separates large droplets in the gas, reducing the droplet content and making the droplet size smaller in the gas entering the filter cartridge 2 subsequently, which is more adaptable to the working conditions of the filter cartridge 2, reducing the working load of the filter cartridge 2 and the possibility of the filter cartridge 2 being blocked due to dealing with a large number of large droplets.

[0047] In some examples, such as Figures 6 to 8 As shown, in this embodiment, to further optimize the usage efficiency and drainage function of the elastic water-absorbing layer 12, a wire mesh 13, a telescopic member 14, and a drainage plate 1013 are designed to achieve automatic drainage of the elastic water-absorbing layer 12.

[0048] The wire mesh 13 closely covers the surface of the elastic water-absorbing layer 12, which can not only ensure that the elastic water-absorbing layer 12 can contact the droplets but also effectively transmit the extrusion force. A telescopic member 14 is arranged on the outer wall of the cover plate 1012. The telescopic member 14 can be an electric push rod or a cylinder, etc., and its telescopic end is connected to a connecting rod 15 that is slidably arranged through the cover plate 1012. The other end of the connecting rod 15 is connected to the wire mesh 13. A sealing structure is designed at the sliding part of the connecting rod 15 on the cover plate 1012 to prevent gas from leaking from the sliding part. A drainage plate 1013 is arranged at the bottom of the opening 1011. The drainage plate 1013 is located below the elastic water-absorbing layer 12 to ensure that the liquid can be discharged into the intake pipe 101.

[0049] When the droplets in the gas are thrown by the centrifugal impeller 11 towards the elastic water-absorbing layer 12 on the inner wall of the cover plate 1012, the elastic water-absorbing layer 12 starts to absorb the droplets. As time goes by, the elastic water-absorbing layer 12 gradually absorbs a large amount of liquid and approaches the saturated state. To ensure the continuous water absorption capacity of the elastic water-absorbing layer 12, the telescopic end of the telescopic member 14 intermittently extends and retracts, driving the wire mesh 13 to intermittently extrude the elastic water-absorbing layer 12 through the connecting rod 15. The extrusion force can be evenly distributed on the elastic water-absorbing layer 12 to squeeze out the absorbed liquid. The squeezed-out liquid drips onto the drainage plate 1013 below under the action of gravity. The inclined design of the drainage plate 1013 guides the liquid to flow towards the drainage port and finally discharges into the intake pipe 101. The telescopic member 14 runs intermittently at a preset time interval to ensure that the elastic water-absorbing layer 12 is squeezed and drained in time after absorbing a certain amount of liquid, avoiding being unable to continue absorbing droplets due to water absorption saturation, thereby maintaining the continuous and efficient water absorption capacity of the elastic water-absorbing layer 12.

[0050] In some examples, such as Figure 9 As shown, in this embodiment, a partition plate 105 is arranged in the housing 1. A plurality of positioning holes 1051 are evenly distributed on the partition plate 105. The number of the positioning holes 1051 is the same as the number of the filter cartridges 2 and their positions correspond one by one. The top end of the filter cartridge 2 can be inserted into the positioning holes 1051, so that the filter cartridge 2 remains stable during the gas-liquid separation process, avoiding affecting the gas-liquid separation effect due to the shaking of the filter cartridge 2.

[0051] The intake pipe 101 and the exhaust pipe 102 are respectively located on both sides of the partition plate 105. The side where the intake pipe 101 is located is the gas-liquid mixed gas inlet area, and the side where the exhaust pipe 102 is located is the gas discharge area after being separated by the filter cartridge 2. Such a layout enables the gas-liquid mixed gas to enter from the intake pipe 101 and must pass through the filtration and separation of the filter cartridge 2 before it can reach the exhaust pipe 102 and be discharged from the housing 1.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit them. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
