Description

Technical Field

[0001] The present invention relates to the technical field of absorption towers, and in particular to an absorption tower. Background Art

[0002] At present, amine escape in the absorber is an important environmental and industrial problem, because amine is a volatile organic compound (VOC), and its emission will not only lead to the loss of absorbent, increase the system operation cost, but also may cause harm to the environment and human health. Conventional methods for treating amine escape in the absorber in the prior art include the following: water washing method: by installing a water washing tower at the outlet of the absorber, the flue gas is fully contacted with water by spraying, and the volatile amine in the gas phase is absorbed. The water washing method can effectively capture the escaped amine, but multiple water washings may be required to achieve a higher capture efficiency; acid washing method: using an acidic solution instead of water for washing can improve the absorption efficiency of amines, especially for amines with higher volatility. Acid washing can reduce the concentration of amines escaping into the flue gas, but may involve additional acid consumption and processing costs; additive method: adding specific chemical substances such as alcohols, alcohol amines, inorganic salts, etc. to the absorption liquid to reduce the volatility of amines. Additives can reduce the concentration of free amines in the liquid phase by forming hydrogen bonds or complexes, thereby inhibiting the volatilization and escape of amines.

[0003] However, all of the above methods require sufficient water or acid or additives, and consume a lot of water or acid or additives, which are not easy to operate, making the process operation of the internal structure of the absorption tower more complicated and costly.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] like Figure 1 As shown, an embodiment of the present invention provides an absorption tower, which includes: a tower body 10, an electrostatic precipitator 40, a dry bed 20, a concentration detection element 50 and a control element. The tower body 10 has an air inlet 11, an air outlet 12 and a cavity 13 connected to the air inlet 11 and the air outlet 12, and the air inlet 11 is located below the air outlet 12; the electrostatic precipitator 40 and the dry bed 20 are both arranged in the cavity 13; the concentration detection element 50 is arranged in the cavity 13, and the concentration detection element 50 is used to detect the concentration of the flue gas components in the cavity 13. The electrostatic precipitator 40 and the dry bed 20 are both connected to the control element, and the control element adjusts the operating parameters of the electrostatic precipitator 40 and / or the operating parameters of the dry bed 20 according to the concentration detected by the concentration detection element 50.

[0035] The absorption tower provided in this embodiment, through the structure of combining the electrostatic precipitator with the dry bed 20 and the heat exchanger 30, does not need to add additional water or acid or additives, which can not only improve the dust removal effect, but also effectively reduce energy consumption. In addition, the structure in this embodiment can also facilitate the flexible adjustment of the operating parameters of the electrostatic precipitator 40 and / or the operating parameters of the dry bed 20 according to the concentration of the flue gas components in the cavity 13, so as to make adaptive adjustments according to actual needs. Through precise control, it is possible to further reduce energy consumption while ensuring the dust removal effect. Therefore, the absorption tower provided in this embodiment can solve the technical problem that the absorption tower in the prior art often needs to add a large amount of water or acid or additives, resulting in high costs.

[0036] Specifically, the gas in the absorption tower flows from the gas inlet 11 to the gas outlet 12 , and flows out through the gas outlet 12 .

[0037] In this embodiment, the electrostatic precipitator 40 adsorbs the flue gas in the cavity 13 by generating an electrostatic field, and the drying bed 20 includes a motor and a fan, and the motor drives the fan to operate; the control component adjusts the voltage of the electrostatic field of the electrostatic precipitator 40 and / or the operating frequency of the motor of the drying bed 20.

[0038] In this embodiment, the electrostatic precipitator 40 is arranged above the drying bed 20, and the concentration detection member 50 includes a first detection unit 51 and a second detection unit 52. The first detection unit 51 is arranged on the side of the drying bed 20 close to the electrostatic precipitator 40, and the second detection unit 52 is arranged on the side of the electrostatic precipitator 40 close to the air outlet 12. The control member adjusts the voltage of the electrostatic field and / or the operating frequency of the motor of the drying bed 20 according to the concentration value detected by the first detection unit 51 and the concentration value detected by the second detection unit 52. In this way, the electrostatic precipitator 40 and the drying bed 20 can be better adaptively adjusted.

[0039] Specifically, when the concentration value detected by the second detection unit 52 is less than the concentration value detected by the first detection unit 51, and the difference between the concentration value detected by the second detection unit 52 and the concentration value detected by the first detection unit 51 is within the preset difference range, the control unit controls the dry bed 20 to operate and controls the electrostatic precipitator 40 to stop operating; when the concentration value detected by the second detection unit 52 is less than the concentration value detected by the first detection unit 51, and the difference between the concentration value detected by the second detection unit 52 and the concentration value detected by the first detection unit 51 exceeds the preset difference range, the control unit controls both the dry bed 20 and the electrostatic precipitator 40 to operate; when the concentration detected by the second detection unit 52 is greater than the concentration detected by the first detection unit 51, the voltage of the control electrostatic field is increased and / or the operating frequency of the control motor is increased. With such a setting, it is convenient to improve the control accuracy of the electrostatic precipitator 40 and the dry bed 20, and to better ensure the flexibility of regulation.

[0040] Specifically, the absorption tower in this embodiment also includes a particle size detection structure. By detecting the particle size and concentration and determining the selected outlet, only the outlet of the dry bed 20 dust removal can be selected. It can be discharged directly through the dry bed 20, or it can be discharged through the dry bed 20 and the electrostatic precipitator in sequence. This can achieve graded selective dust removal, improve the efficiency of dust removal, and reduce energy usage.

[0041] In this embodiment, the absorption tower further includes a weight detection member 70, a beating member 80 and a collecting member 60, which are arranged below the electrostatic precipitator 40. The weight detection member 70 is used to detect the weight of the electrostatic precipitator 40; the beating member 80 is movably or vibratingly arranged on the electrostatic precipitator 40; the collecting member 60 is arranged below the electrostatic precipitator 40, and the collecting slot of the collecting member 60 is arranged toward the electrostatic precipitator 40; the weight detection member 70 and the beating member 80 are both connected to the control member, and the control member controls the beating member 80 to beat the electrostatic precipitator 40 according to the situation detected by the weight detection member 70, so as to collect the smoke and dust falling from the electrostatic precipitator 40 through the collecting member 60. With such a structural arrangement, it is convenient to effectively beat the dust on the electrostatic precipitator 40, so as to better reabsorb new dust and improve the dust removal effect.

[0042] Specifically, when the weight detection member 70 detects that the weight of the electrostatic precipitator 40 is greater than the preset weight, the control member controls the electrostatic precipitator 40 to stop working, and the control member controls the flapping member 80 to flap the electrostatic precipitator 40, so as to collect the smoke and dust falling from the electrostatic precipitator 40 through the collecting member 60; when the weight of the electrostatic precipitator 40 detected by the weight detection member 70 is less than or equal to the preset weight, the control member controls the electrostatic precipitator 40 to operate and the flapping member 80 to stop working. In this way, the flapping member 80 can be better controlled, so as to better ensure the dust removal effect of the electrostatic precipitator 40.

[0043] In this embodiment, the tower body 10 is provided with an escape port, the collecting member 60 has a dust outlet, and the collecting member 60 is rotatably arranged to move to the dust collecting position and the dust outlet position; when the collecting member 60 is in the dust collecting position, the collecting member 60 is arranged in the cavity 13, and the outer wall of the collecting member 60 blocks the escape port; when the collecting member 60 is in the dust outlet position, at least part of the collecting member 60 extends out of the escape port, so that the dust outlet extends out of the tower body 10. In this way, the dust in the mobile phone parts can be better collected to avoid the situation where the dust in the collecting member 60 is full and overflowing.

[0044] Specifically, the dust outlet is located at the lowest position of the bottom wall of the collecting member 60; a shielding plate is provided at the collecting slot of the collecting member 60, the shielding plate shields part of the collecting slot, and the shielding plate is arranged opposite to the dust outlet; wherein, when the collecting member 60 is in the dust outlet position, the shielding plate and the bottom plate of the collecting member 60 are clamped at the avoidance port to block the avoidance port. With such a structural arrangement, the dust in the collecting member 60 can be effectively discharged.

[0045] In this embodiment, the absorption tower further includes a driving member, which is drivingly connected to the collecting member 60, and drives the collecting member 60 to rotate; the driving member is connected to the control member, and the control member controls the working condition of the driving member according to the number of times the beating member 80 beats; when the number of times the beating member 80 beats exceeds a preset number, the control member controls the driving member to move to the dust discharge position. With such a structural setting, it is convenient to better control the movement of the collecting member 60 to better collect dust.

[0046] Specifically, the absorption tower further includes a blocking plate, which is movably arranged on the collection member 60, and has a blocking position for blocking the dust outlet or a avoiding position for avoiding the dust outlet; when the collection member 60 is in the dust collecting position, the blocking plate is in the blocking position to prevent the collected dust from falling into the absorption tower; when the collection member 60 is in the dust discharging position, the blocking plate is in the avoiding position. With such a structural arrangement, it is convenient to discharge dust through the dust outlet when the collection member 60 is in the dust discharging position.

[0047] In this embodiment, the absorption tower further includes a heat exchanger 30, and the heat exchanger 30 is disposed between the drying bed 20 and the electrostatic precipitator 40. In this way, the flue gas can be effectively cooled.

[0048] Specifically, the dry bed 20, heat exchanger 30, electrostatic precipitator 40, concentration detection element 50, weight detection element 70, beating element 80 and collecting element 60 in this embodiment do not completely block the cross-section of the tower body 10, that is, the gas in the tower body 10 can flow smoothly in the tower body 10 from the air inlet 11 to the air outlet 12.

[0049] In this embodiment, the periphery of the electrostatic precipitator 40 is matched with the periphery of the inner wall of the cavity 13, and the periphery of the electrostatic precipitator 40 is installed on the inner wall of the cavity 13, and a plurality of vents are arranged at intervals on the electrostatic precipitator 40. In this way, it is easy to ensure the normal circulation of the fluid in the cavity 13, and at the same time, it is easy to smoothly and stably remove dust from the gas in the circulation cavity.

[0050] Specifically, the electric precipitator 40 in this embodiment includes a plurality of carbon fiber filaments, which are arranged in a staggered manner to form a plurality of vents. With such a structural arrangement, it is possible to stably form an electric field and adsorb large particles of impurities, thereby ensuring a dust removal effect.

[0051] The absorption tower proposed in this scheme can optimize the dust removal process of industrial flue gas by integrating advanced monitoring technology, intelligent decision-making algorithms and precise actuators. The above settings can not only significantly improve the dust removal efficiency and reduce energy consumption, but also help reduce equipment wear, extend service life, and ensure that emissions always meet environmental standards. The absorption tower monitors the particle size and concentration of particulate matter in the flue gas in real time and intelligently decides the most suitable dust removal path. This flexible dust removal strategy ensures that the best dust removal effect can be achieved under different working conditions. For low-concentration flue gas, the system can be discharged directly to avoid unnecessary energy waste; for medium-concentration flue gas, dry bed 20 dust removal is sufficient to meet emission requirements; and for high-concentration flue gas, the combination of dry bed 20 and electrostatic precipitator ensures efficient dust removal. In addition, through variable frequency speed regulation technology and intelligent start-stop strategy, the system can adjust the operating status of the fan and motor according to actual needs, thereby effectively reducing energy consumption. In addition, by accurately controlling the operating parameters of the dry bed 20 and the electrostatic precipitator 40, the system can further reduce energy consumption while ensuring the dust removal effect. By ensuring that the quality of exhaust gas always meets environmental standards, the system helps reduce the impact of industrial activities on the environment. In addition, the system's intelligent decision-making and execution mechanism can respond to abnormal changes in monitoring data in a timely manner and take corresponding measures to prevent excessive emissions of pollutants.

[0052] In summary, the absorption tower of the present application can not only improve dust removal efficiency and reduce energy consumption through intelligent control strategies, but also reduce environmental pollution and improve the economic benefits of enterprises. With the increasingly stringent industrial environmental protection requirements and the continuous increase in energy costs, such a system will have broad application prospects.

[0053] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: dust removal is performed by combining an electrostatic precipitator and a heat exchanger (fin type), which not only improves the dust removal effect, but also reduces energy consumption. The heat exchanger achieves cooling, and then dust removal is performed by a dry bed and an electrostatic precipitator.
