Description

Technical Field

[0001] The invention relates to the technical field of tail gas absorption towers, in particular to a tail gas absorption tower for chemical production with an anti-blocking mechanism. Background Art

[0002] In the chemical production process, tail gas treatment is a crucial link. As the key equipment for tail gas treatment, the performance of tail gas absorber directly affects the efficiency and effect of tail gas treatment. In addition, if the harmful substances in the tail gas are not effectively treated, it will also cause harm to the environment and human health.

[0003] In the process of treating, the traditional tail gas absorber needs to spray the reactant through the spray assembly, so that the tail gas will contact and react with the reactant when it rises in the absorber, so as to achieve the purpose of purifying the tail gas. However, the existing absorber usually has a spray assembly inside the absorber, and the tail gas is connected to the absorber from the bottom wall of the absorber, and the reactant is sprayed through the spray assembly to directly react with the tail gas. Since the tail gas is simply connected from the bottom of the absorber, the tail gas will directly flow upward along the inner cavity of the absorber, and cannot fully contact with the reactant, resulting in poor reaction effect between the tail gas and the reactant. Summary of the invention

[0004] The invention provides a tail gas absorption tower for chemical production with an anti-clogging mechanism, which can overcome certain defects of the prior art.

[0005] According to the present invention, a tail gas absorption tower for chemical production with an anti-blocking mechanism comprises an absorption tower body, an inner cavity is formed inside the absorption tower body, two packing plates are detachably provided inside the inner cavity, the two packing plates divide the inner cavity into a first reaction chamber, a second reaction chamber and a third reaction chamber which are arranged in sequence from top to bottom, the top walls of the two packing plates are detachably provided with a first gas pipeline communicating with a lower layer along the axis of the inner cavity, and the top wall of the partition plate is detachably provided with a second gas pipeline along the axis of the inner cavity;

[0006] A plurality of downwardly inclined inclined tubes are formed at equal intervals at the top of the outer walls of the first gas pipeline and the second gas pipeline, and the inclined tubes are used to spray the tail gas downward along the inclined direction of the inclined tubes. An air inlet pipe that is connected to the second gas pipeline is formed on the outer wall of the absorption tower body, and an air pump is provided at the air inlet pipe, and the air pump is used to pressurize the tail gas and transport it to the second gas pipeline;

[0007] A water supply component penetrating the first gas pipeline and the second gas pipeline is provided between the top wall and the bottom wall of the inner cavity, and a spray component for spraying reactants is provided at the corresponding positions of the water supply component and the first gas pipeline and the second gas pipeline.

[0008] It is understandable that key components such as the packing plate, the first gas pipeline and the second gas pipeline are all detachable, which is convenient for cleaning, replacement or maintenance when necessary, which not only increases the service life of the absorption tower but also reduces maintenance costs.

[0009] The first inclined portion is provided to prevent the reactants from accumulating at the connection between the filler plate and the first gas pipeline.

[0010] A recessed portion for storing fillers is formed on the top wall of the filler plate, a plurality of through holes for reactants to pass through are formed on the bottom wall of the recess, a threaded hole matching the first gas pipeline is formed along the axis of the inner cavity of the recess, and a first inclined portion is formed at the threaded hole, which contacts the first gas pipeline and is inclined downward toward the recess.

[0011] The above structure facilitates reaction filtration of the mixture after the reaction of the reactant and the tail gas, thereby improving the treatment effect of the tail gas.

[0012] The first inclined portion is provided to prevent the reactants from accumulating at the connection between the filler plate and the first gas pipeline.

[0013] It can be understood that the provision of the threaded holes enables the first gas pipeline to be conveniently installed on the filler plate and is also convenient for disassembly and maintenance when necessary.

[0014] Preferably, a second inclined portion inclined downward is formed on the top wall of the first gas pipeline, and a matching hole matching with the outer wall of the water supply component is formed on the top wall of the first gas pipeline.

[0015] The above structure prevents the reactant or the mixture of the reactant and the tail gas from accumulating on the top wall of the first gas transmission pipeline.

[0016] Preferably, a water delivery channel is formed inside the water supply member, an expansion cavity is formed at the corresponding position of the water supply member and the spray member, and a water outlet for installing the spray member is formed at the expansion cavity.

[0017] Through the above structure, the reactant can be continuously supplied to the spraying part through the water supply part, and the structure is compact and reasonable.

[0018] It can be understood that the corresponding spraying parts are supplied in the first reaction chamber, the second reaction chamber and the third reaction chamber respectively, so that reactions can be carried out in each of the first reaction chamber, the second reaction chamber and the third reaction chamber, thereby improving the reaction effect.

[0019] Preferably, the spraying member includes a water pipe connected to the water outlet and a mounting ring sleeved on the outer wall of the first gas pipeline, the mounting ring is provided with a fixing for installing the water pipe, and the water pipe is provided with a nozzle for spraying the reactant.

[0020] By setting the mounting ring and the fixing member, the stability and firmness of the spraying member on the first gas pipeline are ensured to prevent the spraying member from moving or leaking during operation.

[0021] Preferably, a bracket is provided at the bottom wall of the first gas transmission pipeline, and a plurality of knocking components located below the filler plate are provided at the bottom wall of the bracket, and the knocking components are used to knock on the bottom wall of the filler plate.

[0022] The above structure makes it easy to knock the filler plate to prevent the filler from clogging the through hole.

[0023] It is understandable that when the filler in the packing plate is vibrated, it will move slightly, increasing the contact area between the exhaust gas and the filler surface, accelerating the reaction rate, helping the exhaust gas to be evenly distributed in the molecular sieve, avoiding local saturation, and improving the reaction efficiency and uniformity of the reaction.

[0024] Preferably, an equipment cavity is formed at the bottom wall of the inner cavity, a water supply tank connected to the water supply component is provided in the equipment cavity, a water inlet pipe connected to the water supply tank is provided at the outer wall of the absorption tower body, a water pump is provided at the water inlet pipe, the water pump is used to pressurize the reactants and transport them to the inside of the water supply tank, and an air outlet pipe is formed at the top wall of the inner cavity.

[0028] Preferably, the knocking assembly includes a hinged seat arranged at the bottom wall of the bracket, a knocking arm is rotatably arranged at the hinged seat, a ball head is arranged at one end of the knocking arm to contact the bottom wall of the filler plate, a fixing plate is arranged at the other end of the knocking arm, an inclined surface is formed at the bottom wall of the fixing plate, and a spring is arranged between the knocking arm and the bracket, and the spring is used to provide an elastic force to keep the knocking arm pressed upward;

[0029] A driving member corresponding to the fixed plate is formed on the outer wall of the water supply member, and a convex portion matching the inclined surface is formed on the outer wall of the driving member. The driving member is used to intermittently drive the knocking component to knock the bottom wall of the filling plate.

[0030] Through the intermittent rotation of the driving member, the bottom wall of the filler plate is intermittently knocked, thereby preventing the filler from clogging the through hole and affecting the passage of the exhaust gas and the mixture after the exhaust gas reaction.

[0031] Preferably, both the first gas pipeline and the second gas pipeline are provided with a wind wheel connected to the outer wall of the water supply component, and the wind wheel is used to drive the water supply component to rotate; and a through opening corresponding to the wind wheel is formed on the outer wall of the bracket.

[0032] The wind wheel is connected to the outer wall of the water supply part and is respectively arranged in the first gas pipeline and the second gas pipeline, ensuring that when the gas passes through the first gas pipeline and the second gas pipeline, it can directly act on the wind wheel, thereby generating a rotational force, thereby driving the water supply part to rotate, and then allowing the spraying part to rotate and spray, thereby improving the spraying effect, and utilizing the kinetic energy of the gas to drive the rotation of the water supply part, without the need for additional electricity or mechanical drive devices, thereby achieving energy saving and self-driving effects.

[0033] It can be understood that the opening enables the wind wheel to absorb the exhaust gas in the horizontal direction, and the exhaust gas can also drive the wind wheel in the horizontal direction, thereby improving the rotation effect of the wind wheel.

[0034] During use, when the gas passes through the second gas pipeline, it will directly impact the blades of the wind wheel, generating a rotational force to drive the water supply part to rotate around its axis, and cooperate with the first gas pipeline, the second gas pipeline and the inclined pipe to change the delivery direction of the exhaust gas, so that the downward exhaust gas and the upward exhaust gas are sprayed out, which can form a step-by-step contact and mixing with the reactants, thereby improving the mixing rate of the reactants and the exhaust gas.

[0035] It can be understood that the wind wheel can not only change the flow direction and flow rate of the exhaust gas, but also drive the water supply part and the spray part to rotate, thereby improving the practicality of the device.

[0036] The beneficial effects of the present invention are as follows:

[0037] 1. The contact time between the tail gas and the reactant can be increased by setting the first reaction chamber, the second reaction chamber and the third reaction chamber. The tail gas can be ejected along the inclined direction of the inclined tube by coordinating the setting of the first gas pipeline, the second gas pipeline and the inclined tube, thereby changing the flow rate and flow direction of the tail gas in the first gas pipeline or the second gas pipeline, and increasing the mixing time of the reactant and the tail gas. In addition, the wind wheel is used to introduce part of the tail gas into the first gas pipeline in the first reaction chamber through the first gas pipeline, and the flow rate and flow direction of the tail gas are changed again through the corresponding inclined tube, thereby improving the fluidity of the tail gas, so that the tail gas reactant and the tail gas are fully contacted and mixed, greatly improving the mixing degree of the tail gas and the reactant, and thus improving the reaction effect.

[0038] 2. The wind wheel is connected to the outer wall of the water supply part and is respectively arranged in the first gas pipeline and the second gas pipeline, ensuring that when the gas passes through the first gas pipeline and the second gas pipeline, it can directly act on the wind wheel, thereby generating a rotational force, thereby driving the water supply part to rotate, and then allowing the spraying part to rotate and spray, thereby improving the spraying effect, and using the kinetic energy of the gas to drive the rotation of the water supply part, without the need for additional electricity or mechanical drive devices, thereby achieving energy saving and self-driving effects.

[0053] Among them, a water outlet pipe which is connected with the third reaction chamber 170 is provided on the outer wall of the absorption tower body 110, and the water outlet pipe is used to discharge the mixture after the tail gas reaction.

[0054] The exhaust gas absorption tower for chemical production with an anti-clogging mechanism disclosed in the present invention can increase the contact time between the exhaust gas and the reactant by disposing the first reaction chamber 150, the second reaction chamber 160 and the third reaction chamber 170, and cooperate with the disposing of the first gas pipeline 180, the second gas pipeline 181 and the inclined tube 540 so that the exhaust gas can be ejected along the inclined direction of the inclined tube 540, thereby changing the flow rate and flow direction of the exhaust gas in the first gas pipeline 180 or the second gas pipeline 181, and increasing the mixing time of the reactant and the exhaust gas. In addition, the wind wheel 430 is cooperated to introduce part of the exhaust gas into the first gas pipeline 180 in the first reaction chamber 150 through the first gas pipeline 180, and the flow rate and flow direction of the exhaust gas are changed again through the corresponding inclined tube 540, thereby improving the fluidity of the exhaust gas, so that the exhaust gas reactant and the exhaust gas are fully contacted and mixed, greatly improving the mixing degree of the exhaust gas and the reactant, and thus improving the reaction effect.

[0055] It can be understood that key components such as the filler plate 140, the first gas pipeline 180 and the second gas pipeline 181 are all detachable, which is convenient for cleaning, replacement or maintenance when necessary, which not only increases the service life of the absorption tower but also reduces maintenance costs.

[0056] In this embodiment, a recess 510 recessed inwardly for storing fillers is formed on the top wall of the filler plate 140, and a plurality of through holes 520 for reactants to pass through are formed on the bottom wall of the recess 510. A threaded hole that cooperates with the first gas pipeline 180 is formed along the axis of the inner cavity of the recess 510, and a first inclined portion 530 is formed at the threaded hole, which contacts the first gas pipeline 180 and is inclined downward toward the recess 510.

[0057] The above structure facilitates reaction filtration of the mixture after the reaction of the reactant and the tail gas, thereby improving the treatment effect of the tail gas.

[0058] The first inclined portion 530 is provided to prevent the reactants from accumulating at the connection between the filler plate 140 and the first gas pipeline 180 .

[0059] It can be understood that the provision of the threaded holes enables the first gas pipeline 180 to be conveniently installed on the filler plate 140 and is also convenient for disassembly and maintenance when necessary.

[0060] In this embodiment, a second inclined portion 550 inclined downward is formed on the top wall of the first gas pipeline 180 , and a matching hole 560 matching with the outer wall of the water supply component 220 is formed on the top wall of the first gas pipeline 180 .

[0061] The above structure prevents the reactants or the mixture of reactants and tail gas from accumulating on the top wall of the first gas pipeline 180 .

[0062] In this embodiment, a water delivery channel 310 is formed inside the water supply member 220 , an expansion cavity 320 is formed at the corresponding position of the water supply member 220 and the spray member 340 , and a water outlet 330 for installing the spray member 340 is formed at the expansion cavity 320 .

[0063] Through the above structure, the reactant can be continuously supplied to the spraying member 340 through the water supply member 220, and the structure is compact and reasonable.

[0064] It is understandable that the corresponding spraying members 340 are supplied in the first reaction chamber 150 , the second reaction chamber 160 , and the third reaction chamber 170 , respectively, so that reactions can be carried out in each of the first reaction chamber 150 , the second reaction chamber 160 , and the third reaction chamber 170 , thereby improving the reaction effect.

[0065] In this embodiment, the spraying member 340 includes a water pipe 720 connected to the water outlet 330 and a mounting ring 710 sleeved on the outer wall of the first gas pipeline 180, and a fixing member 730 for installing the water pipe 720 is provided at the mounting ring 710, and a nozzle 740 for spraying the reactant is provided at the water pipe 720.

[0066] By providing the mounting ring 710 and the fixing member 730 , the stability and firmness of the spraying member 340 on the first gas pipeline 180 are ensured to prevent the spraying member 340 from moving or leaking during operation.

[0067] Example 2

[0068] See Figure 2-7 This embodiment also provides a tail gas absorption tower for chemical production with an anti-blocking mechanism, which differs from Embodiment 1 in that a bracket 410 is provided at the bottom wall of the first gas pipeline 180, and a plurality of knocking components 420 located below the packing plate 140 are provided at the bottom wall of the bracket 410, and the knocking components 420 are used to knock on the bottom wall of the packing plate 140.

[0069] The above structure makes it easy to knock the filler plate 140 to prevent the filler from clogging the through hole 520 .

[0070] It is understandable that when the filler in the filler plate 140 is vibrated, it will move slightly, increasing the contact area between the exhaust gas and the filler surface, accelerating the reaction rate, helping the exhaust gas to be evenly distributed in the molecular sieve, avoiding local saturation, and improving the reaction efficiency and uniformity of the reaction.

[0071] In this embodiment, an equipment cavity 130 is formed at the bottom wall of the inner cavity, and a water supply tank 230 connected with the water supply component 220 is provided in the equipment cavity 130. A water inlet pipe 250 connected with the water supply tank 230 is provided at the outer wall of the absorption tower body 110. A water pump is provided at the water inlet pipe 250. The water pump is used to pressurize the reactants and transport them to the inside of the water supply tank 230. An air outlet pipe 210 is formed at the top wall of the inner cavity.

[0072] Through the above structure, the reactant in the water supply tank 230 can be stably delivered to the water supply member 220.

[0073] In this embodiment, the bottom of the water supply member 220 is rotatably disposed at the water supply tank 230, a fixing frame is provided at the air outlet pipe 210, and the top of the water supply member 220 is rotatably disposed at the fixing frame.

[0074] The above structure facilitates the rotation along the water supply tank 230 and the fixing frame.

[0075] In this embodiment, the knocking assembly 420 includes a hinge seat 620 disposed at the bottom wall of the bracket 410, a knocking arm 630 is rotatably disposed at the hinge seat 620, a ball head 640 is disposed at one end of the knocking arm 630 to contact the bottom wall of the filler plate 140, a fixing plate 650 is disposed at the other end of the knocking arm 630, an inclined surface 660 is formed at the bottom wall of the fixing plate 650, and a spring 670 is disposed between the knocking arm 630 and the bracket 410, and the spring 670 is used to provide an elastic force to keep the knocking arm 630 pressed upward;

[0076] A driving member 350 corresponding to the fixing plate 650 is formed on the outer wall of the water supply member 220 . A convex portion cooperating with the inclined surface 660 is formed on the outer wall of the driving member 350 . The driving member 350 is used to intermittently drive the knocking assembly 420 to knock on the bottom wall of the filling plate 140 .

[0077] By intermittently rotating the driving member 350, intermittent knocking of the bottom wall of the filler plate 140 is achieved, thereby preventing the filler from clogging the through hole 520 and affecting the passage of the exhaust gas and the mixture after the exhaust gas reaction.

[0078] In this embodiment, both the first gas pipeline 180 and the second gas pipeline 181 are provided with a wind wheel 430 connected to the outer wall of the water supply component 220, and the wind wheel 430 is used to drive the water supply component 220 to rotate; a through opening 610 corresponding to the wind wheel 430 is formed on the outer wall of the bracket 410.

[0079] The wind wheel 430 is connected to the outer wall of the water supply component 220 and is respectively arranged in the first gas pipeline 180 and the second gas pipeline 181, ensuring that when the gas passes through the first gas pipeline 180 and the second gas pipeline 181, it can directly act on the wind wheel 430, thereby generating a rotational force, thereby driving the water supply component 220 to rotate, and then allowing the spraying component 340 to perform rotational spraying, thereby improving the spraying effect, and utilizing the kinetic energy of the gas to drive the rotation of the water supply component 220, without the need for additional electricity or mechanical drive devices, thereby achieving energy saving and self-driving effects.

[0080] It is understandable that the opening 610 enables the wind wheel 430 to absorb the exhaust gas in the horizontal direction, and the exhaust gas can also drive the wind wheel 430 in the horizontal direction, thereby improving the rotation effect of the wind wheel 430.

[0081] During use, when the gas passes through the second gas pipeline 181, it will directly impact the blades of the wind wheel 430, generate a rotational force, thereby driving the water supply component 220 to rotate around its axis, and cooperate with the first gas pipeline 180, the second gas pipeline 181 and the inclined pipe 540 to change the delivery direction of the exhaust gas, so that the downward exhaust gas and the upward exhaust gas are sprayed out, which can form a step-by-step contact and mixing with the reactants, thereby improving the mixing rate of the reactants and the exhaust gas.

[0082] It can be understood that the wind wheel 430 can not only change the flow direction and flow rate of the exhaust gas, but also drive the water supply component 220 and the spray component 340 to rotate, thereby improving the practicality of the device.
