Description
Technical Field
[0001] This application relates to the field of industrial waste gas treatment technology, and in particular to an industrial waste gas treatment device. Background Technology
[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory area. Industrial waste gas mainly includes sulfur-containing and nitrogen-containing compounds, soot, and industrial dust. When released into the atmosphere, it pollutes the air, and these substances enter the human body through various pathways, seriously endangering human health.
[0003] In existing technologies, wastewater is typically biologically treated in industrial reaction tanks and then transported via pipelines to a boiler combustion chamber for secondary combustion. During the biological treatment process in the reaction tank, gases are generated. The gas pressure inside the reaction tank exceeds the internal pressure of the collection and conveying device, causing a sudden increase in the internal pressure of the pneumatic conveying device. This results in a sharp increase or decrease in the gas delivery rate at the output end of the pneumatic conveying device. Furthermore, the biological treatment process generates gaseous and liquid water, which is then transported along with the treated waste gas to the waste gas combustion chamber. This not only affects the stable combustion temperature of the waste gas combustion chamber but also prevents the utilization of the gaseous and liquid water generated during the biological treatment process.
[0004] Therefore, there is an urgent need for a waste gas treatment device to solve the above problems. Utility Model Content

[0020] Combination Figures 1-7 As shown, an industrial waste gas treatment device includes a biological tank 1, a gas collection hood 2, a transfer pump 3, a buffer assembly 4, a heat exchanger 5, a gas-liquid separation assembly 6, a boiler 7, and a water storage tank 8. The first input end of the biological tank 1 is connected to the output end of an external raw material. The input end of the frustoconical gas collection hood 2 covers the output end of the biological tank 1. The input end of the transfer pump 3 is connected to the output end of the gas collection hood 2. The buffer assembly 4 is disposed inside the gas collection hood 2 to mitigate the impact of gas from the biological tank 1 on the transfer pump 3. The input end of the heat exchanger 5 is connected to the output end of the transfer pump 3, and the output end of the heat exchanger 5 is connected to the input end of the gas-liquid separation assembly 6. The first output end of the gas-liquid separation assembly 6 is connected to the input end of the boiler 7, and its second output end is connected to the input end of the water storage tank 8. The output end of the boiler 7 is connected to the external environment. The output end of the water storage tank 8 is connected to the second input end of the biological tank 1.
[0021] In the above scheme, the biological tank 1 serves as the initial treatment unit. Its output end is equipped with a frustum-shaped gas collection hood 2 to form a directional flow structure, which, combined with the internal buffer component 4, creates a pressure gradient regulation mechanism to effectively balance the pressure fluctuations generated during the biological treatment process. The transfer pump 3 and heat exchanger 5 are connected in series to form an energy conversion link, simultaneously performing heat exchange during the transfer process to create the necessary temperature conditions for subsequent gas-liquid separation. The gas-liquid separation component 6 adopts a dual-output design, introducing the separated gas into the boiler 7 for combustion, while the liquid water is returned to the biological tank 1 through the storage tank 8, ensuring both combustion temperature stability and achieving closed-loop utilization of water resources.
[0022] The buffer assembly 4 includes a first support plate 41, a second support plate 42, a first elastic element 44, a second elastic element 45, a third support plate 43, a connecting rod, and a fourth support plate. One end of the first support plate 41 is hinged to the inner wall of the opening of the gas collecting hood 2, and the other end extends horizontally toward the center of the gas collecting hood 2. One end of the second support plate 42 is hinged to the inner wall of the gas collecting hood 2 on the side opposite to the first support plate 41, and the other end extends toward the first support plate 41 and abuts against the end of the first support plate 41 away from the gas collecting hood 2. One end of the first elastic element 44 is fixed to the inner wall of the gas collecting hood 2. The first support plate 41 is fixedly connected to the second support plate 42 on the side away from the biological pool 1, and the other end of the second elastic member 45 is fixedly connected to the inner wall of the gas collection hood 2. The other end of the second elastic member 45 is fixedly connected to the side of the second support plate 42 away from the biological pool 1. The periphery of the third support plate 43 is fixedly connected to the inner wall of the gas collection hood 2 and is spaced above the first support plate 41 and the second support plate 42. The third support plate 43 has a plurality of air holes 431 penetrating along its thickness direction. The core of the plurality of air holes 431 is set at an angle to the thickness direction of the third support plate 43.
[0023] In the above scheme, the first support plate 41 and the second support plate 42 are hinged to form a movable support structure. Their ends abut against each other to form a dynamic seal, which can generate displacement under gas impact to absorb kinetic energy. The first elastic element 44 and the second elastic element 45 act on the first support plate 41 and the second support plate 42 respectively, providing reverse buffering force through elastic deformation, forming a double elastic buffering mechanism. The third support plate 43 serves as a secondary buffer layer. Its inclined vent 431 design deflects the airflow direction, achieving kinetic energy dissipation by changing the airflow path. The structure of the vent 431 at an angle to the thickness direction can guide the airflow to generate vortices, further reducing the airflow velocity. The spatial arrangement of each support plate forms a stepped buffer channel. The first support plate 41 and the second support plate 42 constitute the primary buffer layer, and the third support plate 43 constitutes the secondary buffer layer. Through graded buffering, the impact force is attenuated in a stepped manner to mitigate the impact of gas generated during the biological wastewater treatment process on the pneumatic conveying device.
[0024] The ends of the first support plate 41 and the second support plate 42 that are away from the inner wall of the gas collecting hood 2 are both stepped and form a sealed fit.
[0025] In the above scheme, a mechanical sealing interface is formed by designing the ends of the first support plate 41 and the second support plate 42 as interlocking stepped structures. The stepped structure can increase the sealing path length through multiple contact surfaces. When gas pressure is applied to the support plate, the misalignment of the steps can produce a self-locking effect, preventing gas leakage from the support plate connection.
[0026] The gas-liquid separation assembly 6 includes a shell 61, a primary separation mesh 62, a secondary separation mesh 63, multiple separation plates 64, two vortex plates 65, and a hydrophobic membrane 66. The columnar shell 61 has the primary separation mesh 62 arranged in an integral ring structure at intervals inside. The bottom of the primary separation mesh 62 is fixedly connected to the upper and lower inner walls of the shell 61. The periphery of the shell 61 has a first through hole 611 for communicating with the output end of the heat exchanger 5, a second through hole 612 for communicating with the input end of the water storage tank 8, and a third through hole 613 for communicating with the output end of the boiler 7. The annular secondary separation mesh 63 is arranged at intervals between the primary separation mesh 61 and the secondary separation mesh 62. Inside the off-net 62, the bottom of the secondary separation net 63 is fixedly connected to the upper and lower inner walls of the shell 61; multiple sine and cosine structure separation plates 64 are arranged in a ring in the gap between the primary separation net 62 and the secondary separation net 63; two vortex plates 65 are respectively fixed to the inner walls of the first through hole 611 and the third through hole 613, and vortex holes 651 are opened on the outer end faces of the multiple vortex plates 65 from the outside to the inside, and the core of the vortex hole 651 forms an angle with the axis of the vortex plate 65; the hydrophobic film 66 is attached to the outer side of the secondary separation net 63, and the top end face of the hydrophobic film 66 is flush with the top end face of the secondary separation net 63.
[0027] In the above scheme, the shell 61 serves as a separation chamber. Its annular primary separation mesh 62 achieves initial gas-liquid separation through physical interception, while the secondary separation mesh 63 forms a secondary separation barrier on its inner side. The sine and cosine structured separation plate 64 forms an asymmetric flow channel within the gap between the two separation meshes. By increasing the gas-liquid contact area and changing the airflow direction through its wavy surface, it promotes droplet collision and coalescence. The vortex plate 65 generates rotating airflow through the inclined vortex holes 651, using centrifugal force to enhance liquid water separation. Simultaneously, the vortex plates 65 at the first through hole 611 and the third through hole 613 act on the intake and exhaust stages, respectively, forming a dynamic separation process. A hydrophobic film 66 covers the outside of the secondary separation mesh 63, selectively blocking liquid water penetration through its material properties, ensuring that only dry gas enters the boiler 7 for combustion.
[0028] There are gaps between the plurality of separation plates 64, and there is an included angle between adjacent separation plates 64, the included angle being in the range of 10.5°-15.5°.
[0029] In the above scheme, a series of sine and cosine structure separation plates 64 are arranged in a ring between the primary separation net 62 and the secondary separation net 63 of the gas-liquid separation component 6, and the gap and angle range between adjacent separation plates 64 are defined to form a multi-stage variable airflow channel. The gap design allows the gas to generate a local vortex effect during flow, increasing the contact area between the gas and liquid phases and promoting the adhesion and condensation of liquid water on the surface of the separation plates 64; the angle within a specific range causes the airflow direction to deflect periodically, using the difference in centrifugal force to enhance the stratification effect between gaseous and liquid water. The angle range of 10.5°-15.5° can ensure that the airflow disturbance intensity reaches the separation threshold, while avoiding a surge in airflow resistance due to an excessively large angle, thus achieving a balance between separation efficiency and system energy consumption. Preferably, the angle between adjacent separation plates 64 is 12 degrees.
[0030] The hydrophobic membrane 66 is any one of polyester membrane, polyether membrane, polyamide membrane, and polyimide membrane.
[0031] In the above scheme, staff can select an economical hydrophobic membrane 66 according to actual needs and scenarios. Utilizing the common hydrophobic and high-temperature resistance properties of polyester membranes, polyether membranes, polyamide membranes, and polyimide membranes, a physical barrier layer is formed on the outside of the secondary separation mesh 63. When the gas flow containing liquid water passes through the secondary separation mesh 63, the hydrophobic membrane 66, based on its low surface energy properties, can repel liquid water penetration, forcing the liquid water to coalesce into droplets along the membrane surface and fall, while the gas enters the subsequent process through the membrane pores.
[0032] At least two sets of safety lines 9 are connected in parallel between the output end of the housing 61 and the input end of the boiler 7; each set of safety lines 9 includes a reducer 91, an electric quick-closing valve, a regulating valve 93, a flame arrester 94, and an expansion joint 95; the input end of the reducer 91 is connected in parallel to the third through hole 613 of the housing 61; the input end of the electric quick-closing valve 92 is connected to the output end of the reducer 91, and its output end is connected to the input end of the regulating valve 93; the output end of the regulating valve 93 is connected to the input end of the flame arrester 94; the output end of the flame arrester 94 is connected to the input end of the expansion joint 95; and the output end of the expansion joint 95 is connected to the input end of the boiler 7.
[0033] In the above scheme, reducer 91 is used to connect pipes of different diameters to balance flow rate and pressure; electric quick-closing valve can quickly cut off the pipeline to prevent equipment damage caused by sudden pressure increase or decrease; regulating valve 93 is used to dynamically regulate exhaust gas flow and pressure to maintain stable combustion chamber conditions; flame arrester 94 prevents flame backflow to the separation component or delivery pipeline through physical isolation or cooling, avoiding the risk of explosion; expansion joint 95 absorbs the stress generated by thermal expansion and contraction or vibration of the pipeline through flexible structure, protecting the integrity of the pipeline structure.
[0034] A drainage pump 10 is connected between the second output end of the water storage tank 8 and the second input end of the biological pool 1.
[0035] In the above scheme, by setting up a drain pump 10 to connect the water storage tank 8 and the input end of the biological pool 1, the liquid water after gas-liquid separation can be actively pumped back to the biological pool 1 for recycling. The second output end of the water storage tank 8 serves as the liquid water recovery outlet, the second input end of the biological pool 1 serves as the liquid water reuse inlet, and the drain pump 10 serves as the power drive unit. This solves the problem of liquid water failing to return to the biological pool 1 due to insufficient transport pressure or obstructed path, thus preventing liquid water from entering the combustion chamber of the boiler 7 and causing combustion temperature fluctuations, while also achieving internal recycling of water resources and reducing external water consumption.
