Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment tower technology, and in particular to a cyclone waste gas treatment tower with a guide plate. Background Technology

[0002] In existing industrial waste gas treatment processes, structures such as wet scrubbing towers, cyclone towers, or packed towers are commonly used to purify waste gas. Among them, cyclone waste gas treatment towers are widely used in industries such as chemical, electronics, spraying, and pharmaceutical due to their advantages such as good gas-liquid mixing effect, compact structure, and small footprint. Traditional cyclone waste gas treatment towers generally use tangential air inlets to make the waste gas rise in a spiral manner, while a spray device is installed at the top of the tower to absorb or react the waste gas.

[0003] However, in actual use, the swirling intensity inside the tower is limited by the structural design. Especially under different air volumes and operating conditions, the airflow path stability is insufficient, which can easily lead to problems such as airflow deviation, turbulence, or short circuits, resulting in reduced exhaust gas purification efficiency. Although the tower is equipped with fixed guide plates or turbulence structures, the structure remains unchanged and cannot adapt to air volume fluctuations, resulting in poor stability of the treatment effect. Utility Model Content

[0004] Therefore, it is necessary to address the issues that in practical use, the swirling intensity inside the tower is limited by the structural design, and the airflow path is prone to deviation and turbulence when facing different air volumes or operating conditions, which affects the purification efficiency. Existing fixed guide structures lack adjustment capabilities, are difficult to adapt to changes in air volume, and have poor stability in treatment effect. To address these issues, a swirling exhaust gas treatment tower with a guide plate is needed.

[0005] A cyclone-type exhaust gas treatment tower with a guide plate includes: a treatment tower, an air inlet pipe fixedly installed on one side of the treatment tower, and an exhaust pipe fixedly installed on the top of the treatment tower; an adaptive guide mechanism for adapting to different air inlet velocities, the adaptive guide mechanism being disposed inside the treatment tower; wherein, the adaptive guide mechanism includes a spray pipe fixedly installed inside the treatment tower, the spray pipe being located at the top of the air inlet pipe, a guide component being disposed at the bottom of the spray pipe, and a demisting component being disposed at the top of the spray pipe.

[0006] The flow guiding assembly includes a guide ring fixedly installed inside the processing tower. The guide ring has multiple flow guiding blades arranged in a ring-like manner, and the flow guiding blades are obliquely arranged on the inner wall surface of the guide ring.

[0007] A fixing frame is provided on the side of the guide vane near the inner wall of the guide ring. The fixing frame is fixedly connected to the inner wall of the guide ring. A rotating tube is rotatably installed on the outer side of the fixing frame. The guide vane is fixedly connected to the surface of the rotating tube.

[0008] A guide rod is installed through the surface of the guide vane. The guide rod is in the shape of a ring. Two springs are sleeved through the surface of the guide rod. The two springs are located on both sides of the guide vane. The adjacent side of the two springs is fixedly connected to the guide vane.

[0009] The guide rod is fitted with a protective sleeve on its outer side. The two ends of the two protective sleeves are fixedly connected to the guide vane and the inner wall of the guide ring, respectively. Both springs are located inside the protective sleeves.

[0010] A flow guide ring is fixedly installed at the bottom of the guide ring, and a flow guide cone is fixedly installed at the center of the flow guide ring. One side of the flow guide cone extends between multiple flow guide blades.

[0011] The defogging assembly includes a fixed frame that is fixedly installed inside the processing tower, and a defogging core is disposed inside the fixed frame.

[0012] The defogging assembly also includes a fixed rod that is fixedly installed inside the processing tower. The fixed rod is located at the top of the defogging core. An induction fan is rotatably installed on one side of the fixed rod. The other end of the fixed rod extends out of the processing tower and is fixedly connected to a speed sensor. The sensing end of the speed sensor is connected to the induction fan. Beneficial effects

[0013] 1. After the exhaust gas enters the tower, it first passes through the flow guiding component. Multiple inclined fan-shaped blades can automatically open and close under the action of wind pressure, guiding the airflow to form a stable vortex. Compared with the traditional fixed flow guiding structure, this structure can dynamically adjust the guiding angle according to the wind speed change, improve the consistency of the vortex and the gas-liquid contact efficiency. The demisting component is set above the spray section, which can efficiently capture the liquid droplets entrained after spraying, prevent liquid mist from being discharged, ensure clean exhaust, and extend the service life of downstream equipment.

[0014] 2. When exhaust gas passes through the demisting area, the airflow level in the demisting area is sensed in real time by the speed change of the induction fan as it rotates with the airflow. When the demisting core is blocked, the liquid mist is saturated, or there is a partial blockage, the exhaust gas flow rate will decrease, and the rotation speed of the induction fan will decrease accordingly. The speed sensor can detect this change and feed back an abnormal signal, thus realizing online monitoring of the operating status of the demisting component. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined with Figures 1-6 This invention describes a cyclone-type waste gas treatment tower with a guide plate.

[0026] In one embodiment, a cyclone exhaust gas treatment tower with a guide plate includes: a treatment tower 100, an air inlet pipe 200 fixedly installed on one side of the treatment tower 100, and an exhaust pipe 210 fixedly installed on the top of the treatment tower 100; an adaptive guide mechanism 300, which is disposed inside the treatment tower 100 to adapt to different air inlet velocities; wherein, the adaptive guide mechanism 300 includes a spray pipe 310 fixedly installed inside the treatment tower 100, the spray pipe 310 being located at the top of the air inlet pipe 200, a guide component 320 being disposed at the bottom of the spray pipe 310, and a demisting component 330 being disposed at the top of the spray pipe 310.

[0027] In this embodiment, after the exhaust gas enters the tower, it first comes into contact with the flow guiding component 320. The flow guiding component 320, through multiple inclined fan-shaped blades, can achieve adaptive opening and closing of the angle under the action of wind pressure, thereby guiding the exhaust gas to form a stable swirling path. Compared with the traditional fixed flow guiding structure, it can automatically adjust the guiding angle according to different inlet wind speeds, improve the consistency of swirling formation and gas-liquid contact efficiency. The demisting component 330 is set at the top of the spray pipe 310 and is located in the exhaust path of the treatment tower 100. It can perform efficient demisting treatment on the airflow after the spray reaction, effectively capture entrained droplets, prevent the droplets from being discharged with the exhaust gas, ensure the cleanliness of the exhaust gas, and extend the service life of the downstream equipment.

[0028] It should be noted that the existing waste gas treatment tower 100 typically includes basic components such as tower body wall, inlet pipe 200, exhaust pipe 210, spray device, packing layer or hollow sphere, demister and support structure. Its basic function is to complete the purification treatment by internal swirl, spray, absorption and demisting processes after the waste gas enters tangentially or from the bottom.

[0029] The airflow guiding component 320 is located directly above the air intake path. It guides the exhaust gas through an adaptive adjustment structure without blocking the airflow or increasing additional wind resistance. The demisting component 330 is located on the upper part of the tower near the exhaust pipe 210, which is consistent with the position of a traditional demister. It will not change the original demisting process or affect the operation of other purification units in the tower.

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the flow guiding assembly 320 includes a guide ring 321 fixedly installed inside the processing tower 100. Multiple flow guiding blades 322 are arranged inside the guide ring 321. The multiple flow guiding blades 322 are arranged in a ring shape and are obliquely arranged on the inner wall surface of the guide ring 321.

[0031] In this embodiment, the guide vanes 322 are arranged in a ring shape, which can effectively guide the waste gas entering the treatment tower 100, so that the waste gas is deflected at a set angle to form a stable vortex, thereby enhancing the airflow rotation intensity and distribution uniformity inside the tower body, and improving the contact efficiency and reaction sufficiency between the waste gas and the spray absorption liquid sprayed by the spray pipe 310.

[0032] A fixing frame 323 is provided on the side of the guide vane 322 near the inner wall of the guide ring 321. The fixing frame 323 is fixedly connected to the inner wall of the guide ring 321. A rotating tube 324 is rotatably installed on the outer side of the fixing frame 323. The guide vane 322 is fixedly connected to the surface of the rotating tube 324.

[0033] In this embodiment, the guide vane 322 is fixed to the surface of the rotating tube 324, thereby realizing the angle rotation adjustment of the guide vane 322 under the action of airflow. Compared with the traditional fixed-angle guide plate, it can automatically swing according to the intake wind speed of the exhaust gas and the direction of airflow impact. When the wind speed is high, the opening angle increases, guiding the formation of strong vortex; while when the wind speed is low, it automatically falls back to maintain a reasonable channel angle. It has good adaptability and dynamic guiding ability, which can effectively avoid the problem of decreased vortex stability caused by intake fluctuations, and at the same time improve the coherence of the airflow organization and the treatment efficiency inside the treatment tower 100.

[0034] A guide rod 325 is installed through the surface of the guide vane 322. The guide rod 325 is in the shape of a ring. Two springs 326 are sleeved through the surface of the guide rod 325. The two springs 326 are located on both sides of the guide vane 322. The adjacent side of the two springs 326 is fixedly connected to the guide vane 322.

[0035] In this embodiment, the guide vane 322 can deflect at an angle when subjected to exhaust gas pressure. When the pressure weakens, it can automatically return to its original position under the return force of the spring 326, thereby realizing the dynamic response and recovery of the guide angle. The setting of the spring 326 not only improves the adaptability of the guide assembly 320 to different wind speeds, but also avoids the problem that traditional fixed guide plates cannot be adjusted, so that the exhaust gas can form a stable and efficient swirling path under various working conditions.

[0036] The outer side of the guide rod 325 is fitted with a protective sleeve 327. The two ends of the two protective sleeves 327 are fixedly connected to the inner wall of the guide vane 322 and the guide ring 321, respectively. The two springs 326 are located inside the protective sleeves 327.

[0037] In this embodiment, the guide rod 325 and spring 326 are covered and protected by the protective sleeve 327, which effectively prevents dust, corrosive gas or spray liquid mist from entering the interior of the spring 326 mechanism, and prevents the spring 326 from rusting, jamming or failing, thereby improving the stability and service life of the entire adaptive flow guiding structure in humid, highly corrosive and high-frequency operating environments.

[0038] A guide ring 328 is fixedly installed at the bottom of the guide ring 321, and a guide cone 329 is fixedly installed at the center of the guide ring 328. One side of the guide cone 329 extends between multiple guide vanes 322.

[0039] In this embodiment, the guide cone 329 can effectively compensate for the problem of insufficient coverage of the guide vane 322 in the central area. The guide cone 329 is located in the center of the blade ring. Its conical shape can guide the airflow moving in a straight line along the axis to the outer blade area, avoiding the exhaust gas from rising directly without being guided, thus preventing the phenomenon of airflow short-circuiting or direct dead zone.

[0040] like Figure 2 and Figure 6 As shown, the defogging assembly 330 includes a fixed frame 331 that is fixedly installed inside the processing tower 100, and a defogging core 332 is disposed inside the fixed frame 331.

[0041] In this embodiment, droplets entrained in the exhaust gas after spray treatment can be effectively captured and separated, preventing liquid mist from being discharged with the airflow, causing exhaust pollution, or posing a risk of corrosion and blockage to downstream pipelines, fans, and other equipment. The demister core 332 can be made of materials such as corrugated packing, metal wire mesh, or high-efficiency glass fiber filter, which has efficient impact mist capture and inertial separation capabilities, achieving an improvement in droplet removal rate without significantly increasing airflow resistance. The fixing frame 331 is used to stabilize the installation position of the demister core 332, maintaining structural integrity and preventing displacement even at high wind speeds, ensuring long-term stability of the demister efficiency.

[0042] The defogging assembly 330 also includes a fixing rod 333 fixedly installed inside the processing tower 100. The fixing rod 333 is located on top of the defogging core 332. An induction fan 334 is rotatably installed on one side of the fixing rod 333. The other end of the fixing rod 333 extends out of the processing tower 100 and is fixedly connected to a speed sensor 335. The sensing end of the speed sensor 335 is connected to the induction fan 334.

[0043] In this embodiment, when the exhaust gas passes through the demisting area, the airflow level in the demisting area is sensed in real time by the speed change of the induction fan 334 as it rotates with the airflow. When the demisting core 332 is blocked, the liquid mist is saturated, or there is a partial blockage, the exhaust gas flow rate will decrease, and the rotation speed of the induction fan 334 will decrease accordingly. The speed sensor 335 can detect this change and feed back an abnormal signal, thereby realizing online monitoring of the operating status of the demisting component 330.

[0044] It should be noted that the induction fan 334 can be made of lightweight and corrosion-resistant materials such as polypropylene, polytetrafluoroethylene or aluminum alloy, and has multiple blades, which can start to rotate at low wind speeds to ensure the ability to sensitively detect airflow fluctuations.

[0045] The speed sensor 335 is a rotational speed measuring device linked to the induction fan 334. Its sensing end is connected to the induction fan 334, and it can collect the rotational speed of the induction fan 334 in real time through magnetic induction, photoelectric encoding, or Hall element, and feed this data back to the control system or monitoring terminal to determine the operating status of the demisting area. When the speed is lower than the set threshold, it can be determined that the demisting core 332 may have abnormal conditions such as blockage, saturation, or increased wind resistance.

[0046] Working principle: Industrial waste gas enters the treatment tower 100 tangentially through the inlet pipe 200, first contacting the guide assembly 320 located below the spray pipe 310. The guide assembly 320, through the inclined arrangement and rotatable connection structure of multiple guide vanes 322, causes the waste gas to deflect under wind pressure, thus guiding the airflow to form a stable spiral upward path. When the wind speed is high, the angle of the guide vanes 322 automatically increases, enhancing the swirling intensity; when the wind speed decreases, the spring 326 provides a return force, causing the guide vanes 322 to fall back to their initial angle, achieving dynamic adjustment. The guide cone 329 further guides the center... The axial airflow is deflected towards the outer blade area to avoid direct short-circuiting. During the swirling process, the exhaust gas rises to the spray pipe 310, where the nozzle atomizes and sprays the absorbent liquid, ensuring full contact with the rotating airflow and completing purification reactions such as desulfurization and deodorization. Subsequently, the exhaust gas enters the demister assembly 330 located at the top of the tower. The droplets are intercepted and separated by the demister core 332 to prevent liquid-carrying gas from being discharged. To achieve operational status monitoring, the exhaust gas drives the induction fan 334 to rotate as it passes through the demister area. The speed sensor 335 collects the rotation speed in real time to determine whether the airflow is unobstructed. When the speed drops abnormally, the blockage or saturation of the demister core 332 can be identified, enabling an online early warning function.

[0047] It should be noted that the induction fan and speed sensor mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the induction fan and speed sensor can be powered by the built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
