Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a supergravity waste gas treatment device. Background Technology

[0002] In industrial production processes, industries such as chemical, metallurgical, and power generation produce large amounts of waste gas containing harmful pollutants. Direct emission of this waste gas can cause serious air pollution, threatening ecological balance and human health. Therefore, waste gas purification and treatment has become one of the core needs in the field of industrial environmental protection. Hypergravity technology, with its unique advantage of enhancing gas-liquid mass transfer, has gained widespread attention in the fields of waste gas absorption and purification. It accelerates mass transfer and chemical reactions between the gas and liquid phases by simulating a hypergravity environment, and compared to traditional gravity field treatment technologies, it features high reaction efficiency and compact equipment size.

[0003] However, the structural design of existing high-gravity waste gas treatment devices still has certain shortcomings, with most devices employing a cylindrical structure. This type of cylindrical device suffers from low treatment efficiency in practical applications. On the one hand, the flow field distribution inside the cylindrical cavity is uneven, and local eddies are easily formed after the exhaust gas enters the cylinder, which leads to bubble aggregation, excessively fast rising speed, short contact time between the gas and liquid phases and insufficient contact. On the other hand, most cylindrical bubble dispersion mechanisms are single-jet or rotary designs, which make it difficult to achieve uniform dispersion of exhaust gas. The resulting bubbles have a large particle size and a limited gas-liquid contact area, which restricts the improvement of mass transfer efficiency.

[0004] In addition, the internal space layout of the cylindrical device is limited, and the impurity interception and separation structure is difficult to work in coordination with the bubble dispersion mechanism, which can easily cause impurities to accumulate and block the device, further reducing the long-term stable operation efficiency of the device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a supergravity waste gas treatment device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A supergravity exhaust gas treatment device includes: a support frame, a water tank fixedly mounted on the top of the support frame, a solenoid valve mounted on the bottom of the water tank, a filter plate mounted inside the water tank, a water pump mounted on the right side plate of the water tank, a water pipe mounted on the output port of the water pump, the outlet of the water pipe being located above the water tank, a fan fixedly mounted on the top side of the water tank via a fixed base, an exhaust gas tank mounted on the output port of the fan, an exhaust gas outlet mounted on the bottom of the exhaust gas tank, a connecting plate mounted on the bottom left side of the support frame, a bubble generator mounted on the connecting plate, a square frame plate fixedly mounted on the upper left side of the filter plate via a support column, multiple sets of bubble release nozzles mounted on the square frame plate, and the bubble release nozzles being connected to the bubble generator via pipes; The water tank provides a place for the reaction of waste gas and water and stores the liquid medium required for waste gas treatment. The solenoid valve controls the discharge and shut-off of the liquid inside the water tank. The filter plate intercepts and separates solid impurities generated during the waste gas treatment process. The bubble generator disperses the waste gas into microbubbles through multiple sets of bubble release nozzles, increasing the gas-liquid contact area and improving the waste gas treatment efficiency. The fan inlet is connected to the external waste gas pipeline. The waste gas enters the water body through the waste gas tank and outlet, and forms a bubble group through the bubble release nozzles to achieve mass transfer and reaction under hypergravity conditions.

[0007] Preferably, a panel is provided on the left side of the water tank, and a handle is provided on the panel. The panel is used to open the panel and clean the solid impurities on the filter plate after the liquid inside the water tank has been drained.

[0008] Preferably, the bubble release nozzles are evenly distributed in a matrix on the frame plate, and the bubble release nozzles are used to generate micron-sized bubble clusters.

[0009] Preferably, the water tank is also equipped with a pH sensor and a temperature sensor, which are used to monitor water parameters in real time.

[0010] Compared with the prior art, this utility model provides a supergravity waste gas treatment device, which has the following beneficial effects: The water tank, serving as the reaction chamber for waste gas and liquid media, provides a stable spatial foundation for gas-liquid mass transfer. Combined with multiple sets of bubble release nozzles evenly distributed in a matrix on the frame plate, it can disperse waste gas into micron-sized microbubble clusters. Compared to the bubble dispersion effect of existing cylindrical devices, the bubble particle size in this design is smaller and the distribution is more uniform, greatly expanding the contact area between the gas and liquid phases and creating key conditions for efficient mass transfer and chemical reactions.

[0011] The tank's cavity structure ensures stable storage and flow of the liquid medium, avoiding the problems of uneven flow field and bubble aggregation found in existing cylindrical devices. The bubble release nozzles are precisely positioned above the left side of the filter plate inside the tank. As the bubble cluster slowly rises within the tank, it forms sufficient counter-current contact with the liquid medium, extending the gas-liquid contact time. Simultaneously, under hypergravity conditions, the trajectories of the microbubbles are more complex, further enhancing the disturbance and mixing between the gas and liquid phases, significantly improving the absorption and reaction efficiency of pollutants.

[0012] The filter plate and the bubble release nozzle installed inside the water tank complement each other. The filter plate can effectively intercept solid impurities generated during the exhaust gas treatment process, preventing impurities from adhering to the nozzle of the bubble release nozzle and causing blockage, thus ensuring the long-term stable bubble release effect of the nozzle. Meanwhile, the uniform bubble group generated by the bubble release nozzle does not interfere with the interception function of the filter plate. The two form a synergistic working mechanism inside the water tank, which not only ensures the treatment efficiency but also extends the maintenance cycle and service life of the device.

[0015] 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.

[0016] Reference Figures 1-3 As shown, a supergravity exhaust gas treatment device in this embodiment includes a support 1, which provides stable support for the entire device. Its top is fixedly connected to a water tank 3. This fixing method ensures that the water tank 3 will not shift due to internal liquid sloshing or component vibration during operation.

[0017] A solenoid valve 301 is installed at the bottom of the water tank 3. The solenoid valve 301 is connected to the internal cavity of the water tank 3 and is used to precisely control the discharge and shut-off of the liquid medium in the water tank 3, so as to facilitate the adjustment of the liquid replacement frequency according to the treatment requirements. A filter plate 302 is horizontally installed inside the water tank 3. The filter plate 302 is fixedly connected to the inner wall of the water tank 3, which can effectively intercept solid impurities generated during the waste gas treatment process and prevent impurities from being discharged with the liquid or accumulating inside the device.

[0018] A water pump 2 is fixedly installed on the right side plate of the water tank 3. The output port of the water pump 2 is sealed to the water pipe 201 through a pipe. The outlet of the water pipe 201 extends to the top of the water tank 3. This layout allows the water pump 2 to transport externally replenished liquid or circulating liquid in the water tank 3 to the top of the water tank 3, forming a circulating flow of liquid medium and ensuring the stability of the reaction environment.

[0019] The top side of the water tank 3 is fixedly connected to the fan 5 via a mounting bracket. The mounting bracket enhances the stability of the fan 5 installation. The output port of the fan 5 is sealed to the exhaust gas tank 501. The bottom of the exhaust gas tank 501 is provided with an outlet 502, which is connected to the inside of the water tank 3. This allows external exhaust gas to be transported to the exhaust gas tank 501 via the fan 5, and then enter the liquid medium in the water tank 3 through the outlet 502.

[0020] A connecting plate 102 is fixedly installed on the bottom left side of the bracket 1. A bubble generator 4 is installed on the connecting plate 102. A square frame plate is fixedly connected to the upper left side of the filter plate 302 through a support column. Multiple sets of bubble release nozzles 402 are installed on the square frame plate. The bubble release nozzles 402 and the bubble generator 4 are connected in a sealed manner through a pipe. The bubble generator 4 can convert the exhaust gas into microbubbles, which are then released into the liquid medium through the bubble release nozzles 402 to achieve full gas-liquid contact.

[0021] In some examples, a panel 303 is provided on the left side of the water tank 3. The panel 303 is movably connected to the water tank 3 via a hinge, and a handle is fixedly provided on the panel 303. After the liquid in the water tank 3 has been drained, the panel 303 can be easily opened using the handle to directly clean the solid impurities accumulated on the filter plate 302, preventing impurities from clogging the filter plate 302 and affecting the processing efficiency, while also simplifying the maintenance process of the device.

[0022] In some examples, the bubble release nozzles 402 are evenly distributed in a matrix on the frame plate. This distribution allows the bubble release nozzles 402 to form a uniform bubble coverage area in the water tank 3. Combined with the structural design of the nozzles themselves, they can generate micron-sized bubble clusters, which greatly increases the gas-liquid contact area and further improves the reaction efficiency between waste gas and liquid media.

[0023] In some examples, a pH sensor and a temperature sensor are also fixedly installed inside the water tank 3. The detection end of the sensor is in direct contact with the liquid medium, and the data output end is connected to an external control system. Both can monitor the pH value and temperature parameters of the water in real time, providing data support for the operation and control of components such as water pump 2 and fan 5, ensuring that the liquid medium is always under optimal reaction conditions, and improving the stability and compliance rate of waste gas treatment.

[0024] The working principle of this utility model is as follows: When using this high-gravity exhaust gas treatment device, firstly, a suitable installation location should be selected based on the actual working conditions of the industrial exhaust gas treatment site. The support bracket 1 should be placed stably and fixed, utilizing its rigid structure to ensure the stability of the entire device during operation. Next, component connections and debugging should be performed. The inlet of the blower 5 should be sealed to the external exhaust gas pipeline to ensure no leakage along the exhaust gas transport path. The sealing connection between the water pump 2 and the water pipe 201 should be checked to ensure the outlet of the water pipe 201 is precisely aligned with the top of the water tank 3. The connecting pipe between the bubble generator 4 and the bubble release nozzle 402 should be tightened to prevent gas leakage from affecting the bubble generation effect. A pre-mixed liquid medium should be injected into the water tank 3 until the preset liquid level is reached. At this point, the left side panel 303 of the water tank 3 should be closed and locked to ensure the airtightness of the water tank 3. Simultaneously, the solenoid valve 301 should be checked to ensure it is in the closed state. The pH sensor and temperature sensor should be activated for preheating calibration to ensure they can monitor water parameters normally.

[0025] After the device is installed and debugged, the system can be started to enter the waste gas treatment working state. First, the blower 5 is started. Under the negative pressure suction of the blower 5, the external industrial waste gas enters the waste gas tank 501 through the inlet. The waste gas tank 501 buffers and stabilizes the waste gas, avoiding fluctuations in waste gas flow that may affect the treatment effect. Then, the waste gas enters the liquid medium in the water tank 3 through the outlet 502 at the bottom of the waste gas tank 501. Simultaneously, the bubble generator 4 is started. The bubble generator 4 pressurizes and disperses the incoming waste gas, converting it into a group of micron-sized fine bubbles through multiple sets of evenly distributed bubble release nozzles 402 in a matrix. Because the bubble release nozzles 402 are precisely positioned above and to the left of the filter plate 302, the bubble cluster rises slowly under the influence of gravity, forming a full counter-current contact with the liquid medium in the water tank 3. Compared to traditional cylindrical devices, the matrix-distributed nozzles result in smaller and more uniform bubble sizes, greatly expanding the gas-liquid contact area. Simultaneously, the cavity structure of the water tank 3 avoids uneven flow and bubble aggregation, extending the gas-liquid contact time. During the ascent, the trajectory of the microbubbles becomes more complex, further enhancing the disturbance and mixing between the gas and liquid phases. Harmful pollutants in the exhaust gas undergo a full mass transfer reaction with the liquid medium, achieving the absorption and purification of pollutants.

[0026] During the treatment process, pH and temperature sensors collect real-time parameter data of the liquid medium in water tank 3. If the parameters deviate from the optimal reaction range, the liquid circulation can be started or new liquid can be added by adjusting water pump 2: water pump 2 draws the liquid from water tank 3 and transports it to the top of water tank 3 through water pipe 201, forming a circulating flow of the liquid medium and maintaining the stability of the reaction environment. At the same time, solid impurities generated during the waste gas treatment process are efficiently intercepted by filter plate 302 in water tank 3, preventing impurities from adhering to the nozzle of bubble release nozzle 402 and causing blockage, ensuring a long-term stable bubble release effect of the nozzle, while the uniformly rising bubble group does not interfere with the interception function of filter plate 302, and the two form a synergistic working mechanism.

[0027] After the exhaust gas treatment has been running for a certain period, the device maintenance procedure can be initiated based on sensor monitoring data or a preset program. First, shut down the blower 5 and bubble generator 4 to stop exhaust gas input and bubble generation. Open the solenoid valve 301 to discharge the reacted waste liquid and some precipitated impurities from the water tank 3. After the waste liquid is completely discharged, open the tank plate 303 using the handle to directly clean the solid impurities accumulated on the filter plate 302. Simultaneously, check for blockages in the nozzles of the bubble release nozzles 402 and clean them if necessary. After maintenance, close the solenoid valve 301, refill the water tank 3 with new liquid medium, calibrate the sensors, and then restart the device for exhaust gas treatment.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
