Description

Technical Field

[0001] The present application relates to the field of gas-liquid separation devices, and in particular to a gas-liquid separator. Background Art

[0002] The waste gas generated during the production of petroleum products contains a large amount of corrosive droplets and harmful substances. Direct discharge will cause serious air pollution. Therefore, the waste gas usually needs to undergo a series of purification treatments before it can be discharged. At present, during the purification process of waste gas, a gas-liquid separator is usually used to separate and remove the corrosive liquids and harmful substances contained in the waste gas.

[0003] In related technologies, such as Figure 1 The gas-liquid separator includes a separation tower body 1; the top and bottom of the separation tower body 1 are respectively provided with an air outlet pipe 11 and a liquid outlet pipe 12; the inner cavity of the separation tower body 1 is sequentially installed with a cyclone 2 and an adsorption part (specifically, a plurality of coalescing filter elements 3) from top to bottom; wherein, the cyclone 2 includes a cyclone barrel 20, the side of the cyclone barrel 20 is connected with an air inlet pipe 21, and the end of the air inlet pipe 21 away from the cyclone barrel 20 extends out of the separation tower body 1; the bottom of the cyclone barrel 20 is connected with an exhaust pipe 22 and a liquid discharge pipe 23; and a cyclone blade 24 is also arranged in the cyclone barrel 20. After the subsequent exhaust gas enters the cyclone barrel 20 through the air inlet pipe 21, it is centrifugally treated by the cyclone blade 24, and most of the corrosive droplets carried in the exhaust gas are thrown to the inner wall of the cyclone barrel 20 and finally flow to the bottom of the separation tower body 1 through the liquid discharge pipe 23 for temporary storage. After the liquid level of the corrosive liquid at the bottom of the separation tower body 1 rises to a certain height, it is discharged through the liquid discharge pipe 12. The waste gas from which the corrosive liquid is separated by the cyclone 2 is discharged through the exhaust pipe 22 at the bottom of the cyclone 2, and continues to flow upward along the inner cavity of the separation tower body 1, and is discharged from the air outlet at the top of the separation tower body 1 after the harmful impurities are adsorbed by the coalescing filter element 3 at the top of the separation tower body 1.

[0004] With respect to the above-mentioned related technologies, the exhaust gas discharged through the cyclone still contains a small portion of corrosive droplets. At the same time, since the exhaust pipe at the bottom of the cyclone directly faces the bottom of the separation tower body, the exhaust gas subsequently discharged from the exhaust pipe will directly impact and disturb the corrosive liquid stored at the bottom of the separation tower body, causing the liquid to easily splash. During the rising process, the exhaust gas is likely to entrain the corrosive droplets again, thereby causing the exhaust gas subsequently discharged from the air outlet at the top of the separation tower body to still contain a considerable portion of corrosive droplets; therefore, there is room for improvement. Summary of the invention

[0005] In order to reduce the amount of corrosive droplets carried in the gas discharged from the air outlet at the top of the separation tower body, the present application provides a gas-liquid separator.

[0006] The present application provides a gas-liquid separator, which adopts the following technical solution:

[0007] A gas-liquid separator comprises a separation tower body, wherein the top and bottom of the separation tower body are respectively provided with an air outlet pipe and a liquid outlet pipe, a cyclone and an adsorption part are sequentially installed in the inner cavity of the separation tower body from bottom to top, and a liquid blocking component is also provided in the inner cavity of the separation tower body, wherein the liquid blocking component is located between the cyclone and the adsorption part, and the liquid blocking component comprises a first liquid blocking plate coaxially supported in the inner cavity of the separation tower body, and a plurality of first air holes are evenly opened on the first liquid blocking plate.

[0008] By adopting the above technical solution, a first liquid baffle plate is arranged between the cyclone and the adsorption part; during the subsequent rising process of the exhaust gas discharged through the exhaust pipe of the cyclone along the inner cavity of the separation tower body, the droplets carried in the exhaust gas collide with the first liquid baffle plate under the action of inertia, and after the small droplets merge into larger droplets, they drip to the bottom of the separation tower body by gravity, effectively reducing the situation in which the subsequent exhaust gas still carries a large number of corrosive droplets when it is discharged from the air outlet pipe on the top of the separation tower body.

[0009] Preferably, a wind shield is also provided at the bottom of the cyclone, a gap is left between the upper surface of the wind shield and the exhaust pipe at the bottom end of the cyclone, and a gap is left between the outer periphery of the wind shield and the outer periphery of the separation tower body.

[0010] By adopting the above technical solution, the wind shield is set to limit the exhaust gas blown out through the exhaust pipe at the bottom of the cyclone from directly impacting and stirring the corrosive liquid at the bottom of the separation tower body, causing disturbance or splashing of the corrosive liquid, so that some droplets are re-entrained into the rising exhaust gas, resulting in an increase in the content of corrosive droplets in the rising exhaust gas; at the same time, the exhaust gas blown out from the exhaust pipe at the bottom of the cyclone can be guided by the wind shield, so that the exhaust gas can better flow to the surroundings of the cyclone and flow upward along the gap between the outer periphery of the cyclone and the separation tower body; a gap is left between the outer periphery of the wind shield and the inner periphery of the separation tower body, so that the droplets dripping from the first liquid baffle plate can flow to the bottom of the separation tower body through the gap.

[0011] Preferably, the liquid baffle assembly also includes a second liquid baffle plate supported in the inner cavity of the separation tower body, the second liquid baffle plate is located above the first liquid baffle plate and has a gap with the first liquid baffle plate, a plurality of second ventilation holes are evenly arranged on the second liquid baffle plate, and the plurality of second ventilation holes are staggered with the plurality of first ventilation holes.

[0012] By adopting the above-mentioned technical scheme, it is beneficial to increase the contact area and contact probability between the liquid retaining assembly and the corrosive droplets entrained in the rising exhaust gas, so that the liquid retaining assembly can better intercept the corrosive droplets carried in the rising exhaust gas, which is beneficial to further reduce the content of corrosive droplets in the exhaust gas discharged from the top outlet of the separation tower body.

[0013] Preferably, the first liquid baffle plate and the second liquid baffle plate are both in the shape of conical plates with the tip facing upward.

[0014] By adopting the above technical solution, by making the first liquid baffle plate and the second liquid baffle plate into conical plate shapes, the corrosive droplets that subsequently impact the bottom sides of the first liquid baffle plate and the second liquid baffle plate can flow to the lower parts of the first liquid baffle plate and the second liquid baffle plate by their own gravity and gather and drip to the bottom of the separation tower body, which is beneficial to reduce the residence time of the corrosive droplets on the first liquid baffle plate and the second liquid baffle plate, so that the first liquid baffle plate and the second liquid baffle plate are not easily corroded and damaged.

[0015] Preferably, the air inlet pipe of the cyclone is also connected to a flushing pipe, and one end of the flushing pipe away from the air inlet pipe is connected to a wind source.

[0016] By adopting the above technical solution, after the subsequent gas-liquid separator stops running and the corrosive liquid accumulated at the bottom of the separation tower body is discharged through the liquid outlet pipe, clean gas can be introduced into the air inlet pipe through the flushing pipe to flush the cyclone, so as to reduce the residual corrosive liquid in the cyclone. At the same time, after the clean gas is discharged from the exhaust pipe at the bottom of the cyclone, it can act on the inner cavity wall at the bottom of the separation tower body to drive the corrosive droplets adhered to the inner cavity wall at the bottom of the separation tower body to flow to the bottom of the separation tower body and be discharged from the liquid outlet pipe, thereby reducing the situation where the droplets adhere to the inner cavity wall of the separation tower body for a long time, causing the inner cavity wall of the separation tower body to be easily corroded.

[0017] Preferably, the bottom lining surface of the separation tower body is covered with a glass fiber reinforced plastic layer.

[0018] By adopting the above technical scheme and setting the fiberglass layer, it is beneficial to reduce the residence time of the subsequent corrosive liquid in the bottom lining of the separation tower, and reduce the situation where the bottom cavity wall of the separation tower body is easily corroded and damaged by corrosive liquid droplets due to long-term adhesion of corrosive liquid droplets to the bottom cavity wall of the separation tower body.

[0019] Preferably, the inner cavity of the separation tower body is provided with a lifting drive member, the lifting drive member is located above the second liquid baffle plate and the lifting drive member is drivingly connected to the second liquid baffle plate to drive the second liquid baffle plate to rise and fall in the longitudinal direction;

[0020] When the lifting drive member drives the second liquid baffle plate to abut against the first liquid baffle plate, the first liquid baffle plate and the second liquid baffle plate cooperate to separate the top cavity and the bottom cavity of the separation tower body.

[0021] By adopting the above technical solution, before the clean gas is subsequently introduced into the cyclone through the flushing pipe, the second liquid baffle plate is driven to move downward and abut against the first liquid baffle plate through the lifting drive member, and the first liquid baffle plate and the second liquid baffle plate cooperate to separate the upper and lower cavities of the separation tower body at this time, thereby limiting the subsequent air discharged from the bottom air outlet of the cyclone from entering the upper cavity of the separation tower body, so that the clean gas can better act on the lower cavity of the separation tower body, and further facilitate the clean gas to better blow the residual droplets on the cavity wall at the bottom of the separation tower body to the bottom of the separation tower body.

[0022] Preferably, a gap is left between the first liquid baffle plate and the inner circumference of the separation tower body, and the second liquid baffle plate abuts against the inner circumference of the separation tower body.

[0023] By adopting the above technical solution, a gap is left between the first liquid baffle plate and the inner periphery of the separation tower body, so that the droplets dripping from the bottom side of the second liquid baffle plate can fall from the gap between the first liquid baffle plate and the separation tower into the bottom of the separation tower body, thereby reducing the accumulation of droplets on the first liquid baffle plate. The outer periphery of the second liquid baffle plate is abutted against the inner periphery of the separation tower body, and the second liquid baffle plate is subsequently driven by the lifting drive member to abut against the first liquid baffle plate, and the gap between the first liquid baffle plate and the inner periphery of the separation tower body can be blocked by the second liquid baffle plate to limit the subsequent clean gas from entering the upper cavity of the separation tower body through the gap between the first liquid baffle plate and the inner periphery of the separation tower body.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. A liquid retaining assembly is arranged inside the separation tower body and is located between the cyclone and the coalescing filter element. The corrosive droplets carried in the exhaust gas rising from the subsequent separation tower body can collide with the bottom sides of the first liquid retaining plate and the second liquid retaining plate. After the small droplets converge into larger droplets, they will drip to the bottom of the separation tower body again, effectively intercepting the droplets carried in the exhaust gas rising from the separation tower body, and reducing the situation where the exhaust gas discharged from the top outlet pipe of the subsequent separation tower body carries corrosive droplets.

[0026] 2. By supporting a funnel-shaped windshield with the tip facing upward at the bottom of the cyclone exhaust pipe, on the one hand, the exhaust gas discharged from the exhaust pipe at the bottom of the cyclone is effectively restricted from directly contacting the corrosive liquid surface at the bottom of the separation tower body, reducing the disturbance and impact of the exhaust gas on the corrosive liquid, which is beneficial to reduce the situation where the exhaust gas re-entrains corrosive droplets during the rising process; on the other hand, the exhaust gas can be guided by the windshield, so that the exhaust gas subsequently discharged from the exhaust pipe at the bottom of the cyclone can flow to the outside of the cyclone through the windshield and rise.

[0027] 3. Through the setting of the lifting drive component, before the clean gas is subsequently introduced into the cyclone inlet pipe, the lifting drive component drives the second liquid baffle plate to abut against the first liquid baffle plate, so that the upper cavity and the lower cavity of the separation tower body are separated by the cooperation of the first liquid baffle plate and the second liquid baffle plate, so that the clean gas subsequently discharged from the exhaust pipe at the bottom of the cyclone can better act on the lower cavity of the separation tower body, so as to utilize the clean gas to better blow the corrosive droplets remaining on the cavity wall of the lower cavity of the separation tower body to the bottom of the lower cavity of the separation tower body for collection.

[0035] The following is combined with Figure 2-5 This application is described in further detail.

[0036] The present application embodiment discloses a gas-liquid separator, referring to Figure 2 and Figure 3, including a separation tower body 1, the top and bottom of the separation tower body 1 are connected to an air outlet pipe 11 and a liquid outlet pipe 12 respectively, the inner cavity of the separation tower body 1 is supported with a cyclone 2, a liquid retaining assembly 4 and an adsorption part in sequence from bottom to top; the adsorption part includes a plurality of coalescing filter elements 3, and the plurality of coalescing filter elements 3 are supported in the inner cavity of the separation tower body 1 through a bracket. The liquid retaining assembly 4 includes a first liquid retaining plate 41 and a second liquid retaining plate 42 supported in the inner cavity of the separation tower body 1, the second liquid retaining plate 42 is located above the first liquid retaining plate 41 and a gap is left between the first and second liquid retaining plates 42, the first and second liquid retaining plates 41 and 42 are evenly provided with a plurality of first air holes 411 and a plurality of second air holes 421, and the plurality of first air holes 411 are staggered with the plurality of second air holes 421.

[0037] During the subsequent rising process of the waste gas discharged through the exhaust pipe 22 at the bottom of the cyclone 2 in the separation tower body 1, the corrosive droplets it carries may collide with the bottom sides of the first liquid baffle plate 41 and the second liquid baffle plate 42 under the action of inertia, and the small droplets will converge into larger droplets and then drip to the bottom of the separation tower body 1 for storage. The first liquid baffle plate 41 and the second liquid baffle plate 42 are used to intercept the corrosive droplets carried in the rising waste gas, thereby reducing the corrosive liquid from contacting the coalescing filter element 3 located at the top of the separation tower body 1 for a long time, thereby affecting the service life of the coalescing filter element 3. On the other hand, it is beneficial to reduce the corrosive droplets carried in the waste gas subsequently discharged from the air outlet pipe 11 at the top of the separation tower body 1.

[0038] The first liquid baffle plate 41 and the second liquid baffle plate 42 are both in the shape of a cone with the tip facing upward. Through the above arrangement, the droplets subsequently accumulated on the bottom sides of the first liquid baffle plate 41 and the second liquid baffle plate 42 can slide to the lower part of the first liquid baffle plate 41 and the second liquid baffle plate 42 by their own gravity, so that smaller droplets can converge to form larger droplets and then drip to the bottom of the separation tower body 1, thereby reducing the residence time of the corrosive liquid intercepted on the first liquid baffle plate 41 and the second liquid baffle plate 42 on the first liquid baffle plate 41 and the second liquid baffle plate 42, thereby reducing the corrosion of the first liquid baffle plate 41 and the second liquid baffle plate 42 by the corrosive droplets.

[0039] Reference Figure 2 and Figure 4The inner cavity of the separation tower body 1 is also provided with a windshield 5; the windshield 5 is located at the bottom of the cyclone 2 and has a gap with the exhaust pipe 22 at the bottom of the cyclone 2; the outer periphery of the windshield 5 has a gap with the inner periphery of the separation tower, and the outer periphery of the windshield 5 is welded to the inner periphery of the separation tower body 1 through a plurality of main connecting plates 51, so as to realize the stable connection of the windshield 5 to the inner periphery of the separation tower body 1. The liquid outlet pipe 12 at the bottom of the cyclone 2 is provided with the windshield 5. On the one hand, it limits the waste gas discharged through the exhaust pipe 22 at the bottom of the cyclone 2 to directly impact and stir the corrosive liquid stored at the bottom of the separation tower body 1, and reduces the situation that the waste gas is easy to re-entrain the corrosive droplets due to the direct impact and stirring of the corrosive liquid by the waste gas; on the other hand, the waste gas discharged through the exhaust pipe 22 at the bottom of the cyclone 2 can be guided and limited by the windshield 5, so that the waste gas can quickly flow to the outside of the cyclone 2 and rise after being discharged from the exhaust pipe 22.

[0040] The wind shield 5 is in the shape of a conical plate with the tip facing upward. The corrosive droplets that subsequently adhere to the wind shield 5 can slide through the wind shield 5 to the outer periphery of the wind shield 5 and fall into the bottom of the separation tower body 1 through the gap between the outer periphery of the wind shield 5 and the inner periphery of the separation tower, which is beneficial to reduce the residence time of the corrosive on the wind shield 5 and reduce the corrosion of the wind shield 5 by the corrosive droplets.

[0041] One end of the air inlet pipe 21 of the cyclone 2 extending out of the separation tower body 1 is connected to a flushing pipe 211 , and one end of the flushing pipe 211 away from the air inlet pipe 21 is connected to an air source, specifically an air compressor or a turbo blower. Through the above arrangement, after the gas-liquid separator stops running and the corrosive liquid stored at the bottom of the separation tower body 1 is discharged through the liquid outlet pipe 12 at the bottom of the separation tower body 1, the clean gas is injected into the cyclone cylinder 20 of the cyclone 2 through the flushing pipe 211 and the air inlet pipe 21 by the gas source, and the clean gas is discharged through the exhaust pipe 22 at the bottom of the cyclone 2; on the one hand, it is beneficial to use the clean gas to flush the cyclone cylinder 20 of the cyclone 2, so as to take out the corrosive liquid remaining in the cyclone cylinder 20, and reduce the residual corrosive liquid droplets in the cyclone cylinder 20; on the other hand, part of the clean gas discharged through the exhaust pipe 22 at the bottom of the cyclone 2 can act on the bottom cavity wall of the separation tower body 1 through the gap between the outer periphery of the wind shield plate 5 and the inner periphery of the separation tower body 1, so as to blow the corrosive liquid droplets remaining on the bottom cavity wall of the separation tower body 1 to the bottom of the separation tower body 1, and reduce the corrosive liquid droplets adhering to the inner lining of the separation tower body 1 for a long time, which makes the inner lining of the separation tower body 1 easy to be damaged. A through-and-off valve is installed on the flushing pipe 211 . Specifically, the through-and-off valve is a butterfly valve. When the exhaust gas enters the cyclone 2 through the air inlet pipe 21 , the flushing pipe 211 is closed by the butterfly valve to limit the exhaust gas from leaking out through the flushing pipe 211 .

[0042] Reference Figure 2 and Figure 3, the inner cavity of the separation tower body 1 is also supported with a mounting plate 43; the mounting plate 43 is located above the second liquid baffle plate 42, and a plurality of connecting rods 431 are connected around the outer periphery of the mounting plate 43, and the ends of the connecting rods 431 away from the mounting plate 43 are welded to the inner periphery of the separation tower body 1, so that the mounting plate 43 is stably mounted in the separation tower body 1, and the mounting plate 43 is installed with a lifting drive member, specifically, the lifting drive is a linear electric cylinder 44, and the telescopic rod of the linear electric cylinder 44 is penetrated through the mounting plate 43 and connected to the top of the second liquid baffle plate 42, so that the lifting drive member is driven to be connected to the second liquid baffle plate 42. Subsequently, the telescopic rod is driven to extend and retract by the linear electric cylinder 44, so that the second liquid baffle plate 42 can be driven to rise and fall vertically. When the second liquid baffle plate 42 abuts against the first liquid baffle plate 41, the first liquid baffle plate 41 and the second liquid baffle plate 42 cooperate to form a blocking structure to separate the top and bottom cavities of the separation tower body 1.

[0043] Through the above arrangement, before the clean gas is subsequently pumped into the cyclone 2 through the gas source, the second liquid baffle plate 42 is first driven downward by the linear electric cylinder 44 and abutted against the first liquid baffle plate 41, so that the top cavity and the bottom cavity of the separation tower body 1 are separated and separated by the cooperation of the first liquid baffle plate 41 and the second liquid baffle plate 42, thereby limiting the clean gas subsequently discharged through the exhaust pipe 22 at the bottom of the cyclone 2 from flowing upward, so that it can better act on the bottom cavity wall of the separation tower body 1, so as to better blow the corrosive droplets remaining adhered to the bottom cavity wall of the separation tower body 1 to the liquid outlet pipe 12 at the bottom of the separation tower body 1.

[0044] The linear electric cylinder 44 is also provided with a protective cover 45, which is made of glass fiber reinforced plastics, and the bottom end of the protective cover 45 is connected to the mounting plate 43 through a flange. The protective cover 45 is used to wrap and protect the linear electric cylinder 44, thereby reducing the possibility that the linear electric cylinder 44 is corroded and damaged by corrosive droplets during the actual use of the rear gas-liquid separator.

[0045] Reference Figure 2 and Figure 5 , a gap is left between the outer periphery of the first liquid baffle plate 41 and the inner periphery of the separation tower body 1, and a plurality of auxiliary connecting plates 412 on the outer periphery of the first liquid baffle plate 41 are welded and fixed to the inner periphery of the separation tower body 1. Through the above arrangement, the first liquid baffle plate 41 is stably installed in the inner cavity of the separation tower body 1, and the corrosive droplets dripping from the bottom side of the second liquid baffle plate 42 can flow into the bottom of the separation tower body 1 through the gap between the outer periphery of the first liquid baffle plate 41 and the inner periphery of the separation tower body 1, thereby reducing the accumulation of corrosive droplets dripping from the bottom side of the second liquid baffle plate 42 on the first liquid baffle plate 41.

[0046] The outer periphery of the second liquid baffle plate 42 is arranged to abut against the inner periphery of the separation tower body 1. Through the above arrangement, after the subsequent linear electric cylinder 44 drives the second liquid baffle plate 42 to abut against the first liquid baffle plate 41, the second liquid baffle plate 42 can block the gap between the outer periphery of the first liquid baffle plate 41 and the separation tower body 1, and then the first liquid baffle plate 41 and the second liquid baffle plate 42 can better cooperate to separate the bottom cavity and the top cavity of the separation tower body 1, thereby limiting the clean gas subsequently discharged from the exhaust pipe 22 at the bottom of the cyclone 2 from flowing upward to the top cavity of the separation tower body 1.

[0047] A balancing pipe 6 is also provided on the periphery of the separation tower body 1, the bottom end of the balancing pipe 6 is connected to the bottom cavity of the separation tower body 1, and the connection point between the balancing pipe 6 and the bottom cavity of the separation tower body 1 is located below the wind shield 5, the top end of the balancing pipe 6 is connected to the top cavity of the separation tower body 1, and the connection point between the balancing pipe 6 and the top cavity of the separation tower body 1 is located above the second liquid baffle 42, and a balancing valve 61 is also installed on the balancing pipe 6. Through the above arrangement, before the subsequent gas source injects clean gas into the cyclone 2, the balancing valve 61 on the exhaust pipe 22 is opened, so that part of the clean gas that subsequently enters the bottom of the separation tower body 1 can be discharged to the top cavity of the separation tower body 1 through the balancing pipe 6, which is beneficial to maintaining the air pressure balance in the separation tower body 1.

[0048] A glass fiber reinforced plastic layer 13 is fixedly arranged in the inner lining of the bottom cavity of the separation tower body 1. The arrangement of the glass fiber reinforced plastic layer 13 can effectively reduce the residence time of subsequent corrosive droplets on the bottom cavity wall of the separation tower body 1, and reduce the long-term adhesion of corrosive droplets on the bottom cavity wall of the separation tower body 1, which causes the bottom cavity wall of the separation tower body 1 to be easily corroded by corrosive droplets, thereby improving the corrosion resistance of the bottom cavity wall of the separation tower body 1.

[0049] The implementation principle of the embodiment of the present application is that during the operation of the gas-liquid separation tower, the waste gas discharged from the exhaust pipe 22 at the bottom of the cyclone 2 moves upward along the separation tower body 1, and the corrosive droplets entrained in the waste gas collide with the first liquid baffle plate 41 and the second liquid baffle plate 42 under the action of inertia, and the small droplets impinging on the first liquid baffle plate 41 and the second liquid baffle plate 42 are gathered into large droplets and then drip to the bottom of the separation tower body 1; the first liquid baffle plate 41 and the second liquid baffle plate 42 are used to intercept the corrosive droplets entrained in the rising waste gas, thereby effectively reducing the content of corrosive droplets in the waste gas subsequently discharged from the air outlet pipe 11 at the top of the separation tower body 1.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
