Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a multi-component intelligent, efficient and environmentally friendly waste gas treatment device. Background Technology

[0002] With rapid industrialization and urbanization, air pollution has become a global environmental problem. As one of the main sources of air pollutants, the effective treatment of exhaust gas emissions is of great significance for improving air quality and protecting the ecological environment. Currently, various types of exhaust gas treatment equipment are available on the market, which can reduce harmful substances in exhaust gases to varying degrees, contributing to environmental protection. These devices typically employ physical, chemical, or biological methods to purify exhaust gases, such as adsorption, absorption, and catalytic oxidation processes.

[0003] Among existing waste gas treatment equipment, packing structures are widely used due to their advantages such as simple construction, convenient operation, and low operating costs. However, these devices still have many shortcomings in practical applications. Due to uneven airflow distribution, local packing loads are often too high, while the utilization rate of other areas is low, thus affecting the overall treatment efficiency. At the same time, the lack of effective airflow guiding structures between packing layers makes it easy for airflow short-circuiting and flow deviation to occur, reducing the gas-liquid mass transfer effect. In addition, existing equipment generally lacks real-time monitoring and intelligent adjustment functions for operating status, making it difficult to effectively cope with complex and changing waste gas compositions and increasingly stringent emission standards. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-component intelligent, efficient and environmentally friendly waste gas treatment device to solve the problems mentioned in the background art, such as uneven airflow distribution, low treatment efficiency, lack of airflow guiding structure and insufficient level of intelligent control in the current packing waste gas treatment devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-component intelligent high-efficiency environmentally friendly waste gas treatment device, comprising a purification chamber body, an air inlet at the bottom of one side of the purification chamber body, an air outlet at the top of the purification chamber body, and a first packing layer, a second packing layer, and a third packing layer arranged sequentially from bottom to top inside the purification chamber body, with an annular support seat below each packing layer, and a flow guide ring seat installed along the top edge of the annular support seat, wherein multiple sets of airflow diversion mechanisms are evenly distributed circumferentially inside the flow guide ring seat, and each set of airflow diversion mechanisms includes a drive module and a flow guide plate connected thereto.

[0007] Preferably, the guide plate has a fan-shaped structure with a wider inner end and a narrower outer end, and the gap between adjacent guide plates forms an airflow passage. Furthermore, the surface of the guide plate is provided with a number of inclined baffles, which are arranged at equal intervals along the length of the guide plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a multi-component intelligent high-efficiency environmentally friendly waste gas treatment device, including a purification chamber body 1, an air inlet 2 at the bottom of one side of the purification chamber body 1, and an air outlet 6 at the top of the purification chamber body 1. Inside the purification chamber body 1, from bottom to top, there are sequentially arranged a first packing layer 3, a second packing layer 4, and a third packing layer 5. Each packing layer has an annular support 7 below it. A guide ring seat 8 is installed along the top edge of the annular support 7. Multiple sets of airflow diversion mechanisms are evenly distributed circumferentially inside the guide ring seat 8. Each set of airflow diversion mechanisms includes a drive module 9 and a guide plate 10 connected to it. Pressure sensors 11 are installed in the middle of the top of each of the first packing layer 3, the second packing layer 4, and the third packing layer 5. Gas flow sensors 12 are installed at the bottom center of packing layer 3, the second packing layer 4, and the third packing layer 5. Meanwhile, pressure sensors 11, which are MPX5050 piezoresistive sensors, are fixed to the center of the top of each packing layer via a threaded connection and connected to the control system via an analog signal line. This is used to collect real-time pressure change data of the airflow above each packing layer. Gas flow sensors 12, which are FS4008 thermal mass flow sensors, are flange-embedded in the center channel at the bottom of each packing layer and connected to the main control module via an I²C communication interface. This is used to monitor the gas flow rate through each packing layer in real time. During equipment operation, the pressure sensors 11 and gas flow sensors 12 work together. The collected pressure and flow data are transmitted to the central control system. The system performs feedback control on the drive module 9 according to the set threshold, dynamically adjusting the angle of the guide plate 10 to achieve intelligent optimization of airflow distribution. At the same time, by comparing and analyzing the data from multiple layers of sensors, it can determine whether the packing layer is blocked or malfunctioning. In this structure, when exhaust gas is introduced into the purification chamber body 1 through the air inlet 2, it undergoes multi-stage purification treatment through the first packing layer 3, the second packing layer 4, and the third packing layer 5. During this process, the annular support seat 7 set under each packing layer provides stable support for the guide ring seat 8. At the same time, multiple sets of airflow diversion mechanisms evenly arranged on the guide ring seat 8 control the guide plate 10 to automatically adjust its angle under the drive module 9, realizing dynamic guidance of airflow direction and speed. This design ensures a more uniform distribution of exhaust gas as it passes through each packing layer, preventing localized flow deviations or short circuits. Furthermore, pressure sensors 11 located at the top center of each packing layer and gas flow sensors 12 located at the bottom center monitor real-time changes in airflow pressure and flow rate, feeding the data back to the control system. This enables intelligent sensing and adjustment of the operating status. This structure effectively solves the problems of decreased treatment efficiency and insufficient ability to handle complex operating conditions caused by uneven airflow distribution, low packing utilization, and lack of intelligent monitoring methods in existing exhaust gas treatment equipment. The drive module 9 includes a drive housing, a servo motor, and a rotating shaft. The servo motor is fixedly installed inside the drive housing, with one end of its output shaft coaxially connected to the rotating shaft. The outer end of the rotating shaft is fixedly connected to the inner end of the guide plate 10.After the servo motor in the drive module 9 is powered on, it drives its output shaft to rotate. The power is transmitted to the inner end of the guide plate 10 through the rotating shaft coaxially connected to the output shaft. Under the protection and fixed support of the drive housing, the guide plate 10 can be precisely adjusted in angle inside the guide ring seat 8. This allows for dynamic control of the exhaust gas flow direction and velocity according to the airflow state, ensuring that the airflow is more evenly distributed when passing through the first packing layer 3, the second packing layer 4, and the third packing layer 5. The guide plate 10 has a fan-shaped structure with a wider inner end and a narrower outer end. The gaps between adjacent guide plates 10 form an airflow passage. Furthermore, the surface of the guide plate 10 is provided with several inclined baffles 13, which are evenly spaced along the length of the guide plate 10. In this structure, the guide plate 10 can gradually gather and guide the airflow, making the exhaust gas form a more uniform distribution before entering the packing layer. The airflow passage formed between adjacent guide plates 10 effectively controls the airflow speed and direction. At the same time, the inclined baffle 13 generates local vortex and disturbance effects when the airflow passes through, further breaking the laminar flow state, enhancing the airflow mixing degree and contact efficiency with the packing, thereby improving the overall mass transfer effect and purification performance. The bottom of the annular support 7 has an arched curved surface structure. The arched curved surface is evenly provided with several guide grooves 14 along the circumference, and the inner wall of the guide grooves 14 is provided with multiple evenly distributed micro guide ribs. The arched curved surface at the bottom of the annular support 7 is designed with its own arc surface... The design guides the airflow smoothly to the next layer of packing material. Simultaneously, multiple guide grooves 14 further divert and conduct the airflow, making the airflow distribution more uniform and avoiding localized concentration or flow deviation. The micro-guide ribs on the inner wall of the guide grooves 14 generate micro-scale disturbances as the airflow passes through, enhancing airflow turbulence and improving the contact efficiency between the airflow and the packing layer, thereby improving the overall purification effect. The first packing layer 3 is a honeycomb activated carbon composite module, the second packing layer 4 is a three-dimensional spherical ceramic structured packing, and the third packing layer 5 is a porous graphene-zeolite composite textured layer. The honeycomb activated carbon composite module of the first packing layer 3 is composed of honeycomb activated carbon blocks and a nano-TiO2 coating, enabling efficient adsorption of large amounts of pollutants in the waste gas. The first layer targets molecular organic pollutants and achieves preliminary photocatalytic degradation of volatile organic compounds under light conditions. The second layer, 4, consists of three-dimensional spherical ceramic structured packings with transition metal oxide catalysts loaded on their surface. Under intermediate temperature conditions, these catalysts can catalytically oxidize and decompose residual organic gases and some nitrogen oxides, achieving flameless combustion purification. The third layer, 5, is a porous graphene-zeolite composite textured layer manufactured using a 3D printing process to create a corrugated structure. It exhibits excellent polar gas adsorption selectivity and synergistic photocatalytic performance, used for deep adsorption and synergistic purification of trace amounts of harmful gases. The three layers work in a progressive manner to achieve adsorption, catalysis, and deep purification functions, significantly improving overall treatment efficiency and adaptability to complex waste gas compositions.

[0018] Working Principle: When using this multi-component intelligent high-efficiency environmentally friendly waste gas treatment equipment, the waste gas first enters the main body 1 of the purification chamber through the air inlet 2. Driven upwards by the airflow, it passes through the first packing layer 3, the second packing layer 4, and the third packing layer 5 for multi-stage purification. During the process of the waste gas passing through each packing layer, the pressure sensor 11 collects the airflow pressure data above each packing layer in real time, and the gas flow sensor 12 simultaneously detects the gas flow changes below each packing layer. The signals are transmitted to the central control system through the analog signal line and the I²C communication interface. The system adjusts the drive based on the data fed back by the sensors. The drive module 9 issues a control command, which starts the servo motor in the drive module 9 and drives the rotating shaft to rotate, thereby adjusting the angle of the guide plate 10 and dynamically adjusting the airflow direction and speed. At the same time, the baffles 13 on the surface of the guide plate 10 move together to enhance the airflow disturbance effect. The arched curved surface structure at the bottom of the annular support 7, together with the guide groove 14 and the micro guide ribs, further guides the airflow evenly, ensuring that the airflow enters the next layer of packing area stably. The purified exhaust gas is finally discharged from the outlet 6. In the entire operation process, a continuous and stable exhaust gas treatment process is achieved, thereby completing a series of tasks.
