Description

Technical Field

[0001] This utility model relates to waste gas treatment technology, and more particularly to a waste gas treatment tank in which waste gas and neutralizing liquid are evenly mixed. Background Technology

[0002] With the acceleration of industrialization, various industrial production activities generate a large amount of waste gas, which often contains a variety of pollutants, such as volatile organic compounds (VOCs), acidic gases, and particulate matter. If discharged directly without effective treatment, it will not only cause serious pollution to the atmospheric environment, leading to environmental problems such as smog and acid rain, but also harm human health, damaging the respiratory and cardiovascular systems of nearby residents. Therefore, efficient waste gas treatment technology is particularly important.

[0003] Currently, common waste gas treatment methods include absorption, adsorption, and combustion, among which using treatment ponds is a frequently used approach. However, existing waste gas treatment ponds have several drawbacks. Regarding the mixing of waste gas and neutralizing liquid, some treatment ponds have unreasonable structural designs and poorly positioned waste gas inlet pipes, leading to uneven mixing, low mass transfer efficiency, and hindering the full chemical reaction. This results in unsatisfactory waste gas treatment effects, making it difficult to meet stringent environmental emission standards.

[0004] In terms of purification processes, traditional treatment ponds rely on a single purification method and lack an effective multi-stage purification mechanism, failing to comprehensively remove various pollutants from waste gas. Furthermore, the adsorption materials are often fixed and difficult to replace, leading to a sharp decline in treatment efficiency once saturated. Many waste gas treatment ponds have complex component connections, making disassembly difficult and causing significant inconvenience for daily maintenance, repairs, and component replacement. Simultaneously, waste gas inlet pipes are prone to blockage due to impurity accumulation, making cleaning cumbersome and time-consuming, increasing equipment operating costs and downtime. In addition, traditional treatment ponds do not prioritize safety monitoring during waste gas treatment, lacking effective means for real-time monitoring of gas concentrations. In the event of gas leaks or abnormal concentrations, timely detection and intervention are difficult, posing significant safety hazards. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model discloses a waste gas treatment tank that can uniformly mix waste gas and neutralizing liquid, achieve good purification results, and is convenient, safe, and reliable in maintenance.

[0006] This utility model discloses a waste gas treatment tank for uniformly mixing waste gas and neutralizing liquid. It includes a treatment tank body, the width of which gradually increases from bottom to top. Several waste gas inlet pipes are installed along one side of the waste gas treatment tank body, extending from top to bottom. A waste gas access pipe is installed above the waste gas inlet pipes. A lower cover plate is installed above the treatment tank body and detachably connected to it. The lower cover plate is recessed from top to bottom. The lower cover plate has a removable absorbent cotton inside and several air holes running through its lower part. The upper cover plate is located above the lower cover plate and is detachably connected to it. The upper cover plate has a groove recessed from top to bottom, and a removable absorbent cake is located inside the groove. Several upper cover plate through holes run through the groove. The top cover plate is located above the upper cover plate and is detachably connected to it. An exhaust gas outlet pipe runs through the top cover plate.

[0007] Furthermore, the air inlet and outlet of the exhaust gas inlet pipe are located on the same axis, and a straight flow channel is formed inside the exhaust gas inlet pipe.

[0008] Furthermore, some exhaust gas inlet pipes are equipped with guide pipes at their outlets to change the direction of the exhaust gas flow to the side closer to the lower cover plate.

[0009] Furthermore, the interior of the treatment tank body is equipped with a stirring assembly, which includes a stirring rod fixed to the bottom of the treatment tank body and a stirring fan located at the end of the stirring rod away from the treatment tank body. The distance between the stirring fan and one side of the bottom of the treatment tank body is greater than the distance between the air outlet of the guide pipe and one side of the bottom of the treatment tank body.

[0010] Furthermore, some exhaust gas inlet pipes and some guide pipes are equipped with diversion fans that can change the gas flow direction.

[0011] Furthermore, the exhaust gas inlet pipe is located on one side of the exhaust gas treatment pool near the middle, and an air compressor capable of compressing the exhaust gas is installed at the inlet of the exhaust gas inlet pipe.

[0012] Furthermore, the connection method between the lower cover plate and the treatment pool, the connection method between the upper cover plate and the lower cover plate, and the connection method between the top cover plate and the upper cover plate are one of the following: bolt connection, screw-on bolt connection, snap-on connection, and tenon and mortise connection.

[0013] Furthermore, a filter screen is installed at the inlet of the exhaust gas inlet pipe, and at least two gas concentration sensors and an alarm device are installed inside the treatment tank body. The two gas concentration sensors are respectively installed on the upper part of the adsorption cotton and the upper part of the adsorption cake, and the alarm device is installed on one side of the outside of the treatment tank body and is connected to the at least two gas concentration sensors.

[0014] Furthermore, activated carbon and zeolite are incorporated into the adsorption cake.

[0015] Beneficial effects:

[0016] In this application, the treatment tank body gradually increases in width from bottom to top, and several exhaust gas inlet pipes introduce exhaust gas to the bottom of the treatment tank. This exhaust gas causes the neutralizing liquid within the treatment tank to tumble, ensuring thorough contact and uniform mixing between the exhaust gas and the neutralizing liquid. This improves the exhaust gas treatment effect and facilitates a full chemical reaction between pollutants in the exhaust gas and components in the neutralizing liquid, thereby enhancing the removal efficiency of harmful substances in the exhaust gas. The adsorption cotton on the lower cover plate and the adsorption cake in the upper cover plate groove are removable, allowing for timely replacement after the adsorption materials become saturated. This ensures the stability and continuity of the adsorption effect and reduces the operating cost of the equipment, eliminating the need to replace the entire cover plate and other components; only the adsorption material needs to be replaced. The adsorption cake in the upper cover plate groove is used for secondary adsorption of the exhaust gas. After treatment with the neutralizing liquid in the treatment tank and initial adsorption by the adsorption cotton on the lower cover plate, the exhaust gas undergoes secondary adsorption by the adsorption cake, further removing residual pollutants and resulting in cleaner exhaust gas, reducing environmental pollution and improving the overall quality of exhaust gas treatment. The system utilizes the energy of exhaust gas to drive the stirring fan and the diverting fan, reducing the energy consumption of additional power equipment; the adsorption material is regenerable, reducing treatment costs; and diverse connection methods meet different needs, improving the overall integrity and stability of the equipment and reducing failure and maintenance costs.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the specific embodiments of the present invention will be clearly and completely described below.

[0021] This utility model discloses a waste gas treatment tank 100 in which waste gas and neutralizing liquid are uniformly mixed, such as... Figure 1 and Figure 2As shown, it includes a treatment tank body 11, the width of which gradually increases from bottom to top. Several exhaust gas inlet pipes 111 are installed along one side of the wastewater treatment tank body, extending from top to bottom. An exhaust gas inlet pipe 112 is installed above each exhaust gas inlet pipe 111. The exhaust gas inlet pipes 111 are used to introduce exhaust gas into the wastewater treatment tank, and the exhaust gas inlet pipe 112 is used to connect to the exhaust gas pipe. The exhaust gas inlet pipe 112 can be disassembled at any time. After the exhaust gas is introduced into the bottom of the exhaust gas treatment tank 100 through the exhaust gas, it can cause the waste gas neutralization liquid in the waste gas treatment tank 100 to tumble, ensuring uniform mixing of waste gas and the waste gas neutralization liquid. The lower cover plate 12 is disposed above the treatment tank body 11 and detachably connected to the treatment tank body 11. The lower cover plate 12 has a recessed groove from top to bottom, and a detachable absorbent cotton 121 is disposed within the groove. The absorbent cotton 121 absorbs both waste gas and moisture within the waste gas. Several air holes penetrate the lower part of the lower cover plate 12 for the passage of waste gas from the wastewater treatment tank. The upper cover plate 13 is disposed above the lower cover plate 12. The upper cover 13 is detachably connected to the lower cover 12. The upper cover 13 is recessed from top to bottom and has a groove. A detachable adsorption cake 131 is provided in the groove. Several through holes are provided in the groove. The adsorption cake 131 is used for secondary adsorption of waste gas. The top cover 14 is located above the upper cover 13 and is detachably connected to the upper cover 13. A waste gas outlet pipe 141 is provided on the top cover 14. In this application, the treatment tank body 11 gradually increases in width from bottom to top, and several exhaust gas inlet pipes 111 introduce exhaust gas to the bottom of the treatment tank. The exhaust gas causes the neutralizing liquid within the treatment tank 100 to tumble, ensuring thorough contact and uniform mixing between the exhaust gas and the neutralizing liquid. This improves the exhaust gas treatment effect and facilitates a full chemical reaction between pollutants in the exhaust gas and components in the neutralizing liquid, thereby enhancing the removal efficiency of harmful substances in the exhaust gas. The exhaust gas inlet pipe 112 is used to connect to the exhaust gas pipe and can be disassembled at any time, facilitating connection to different exhaust gas emission sources. It also facilitates inspection, replacement, and maintenance of the exhaust gas inlet pipe 112 and its connected components, reducing maintenance costs and improving the operability and service life of the equipment. The absorbent cotton 121 on the lower cover plate 12 and the absorbent cake 131 in the groove of the upper cover plate 13 are both detachable, which makes it convenient to replace the absorbent material in time after it becomes saturated, ensuring the stability and continuity of the adsorption effect, and reducing the operating cost of the equipment. There is no need to replace the entire cover plate and other parts; only the absorbent material needs to be replaced.The adsorption cake 131 in the upper cover plate 13 is used for secondary adsorption of waste gas. After the waste gas has been treated by the neutralization liquid in the treatment pool and initially adsorbed by the adsorption cotton 121 in the lower cover plate 12, it can be further adsorbed by the adsorption cake 131 to remove the residual pollutants in the waste gas, making the final discharged waste gas cleaner, reducing environmental pollution, and improving the overall quality of waste gas treatment.

[0022] In one implementation, the inlet and outlet of the exhaust gas inlet pipe 111 are located on the same axis, and a straight flow channel is formed inside the exhaust gas inlet pipe 111. The exhaust gas inlet pipe 111 is used to receive exhaust gas and introduce it into the exhaust gas treatment tank 100. During prolonged use, sludge may accumulate inside the exhaust gas inlet pipe 111. When there is a large amount of sludge, the air intake effect of the exhaust gas inlet pipe 111 may deteriorate. By creating a straight flow channel inside the exhaust gas inlet pipe 111, workers can directly clean it from top to bottom using cleaning tools. The straight flow channel provides a convenient passage for cleaning work. Workers can use simple cleaning tools such as long-handled brushes and push rods to clean directly from top to bottom along the straight flow channel, without needing to use special, more complex tools and techniques as in curved or complex flow channels. This reduces the difficulty of cleaning operations and the professional skills required. The straight flow channel can minimize the impact of sludge accumulation on the air intake effect. Compared to curved or cornered flow channels, straight flow channels do not have dead corners or vortex areas where waste sludge can easily accumulate. Waste sludge is more easily discharged under the action of gravity and airflow, thus keeping the pipeline unobstructed for a longer period of time and ensuring that the waste gas can continuously and stably enter the waste gas treatment pool 100.

[0023] As one implementation method, the outlet of part of the exhaust gas inlet pipe 111 is provided with a guide pipe 113 that changes the direction of the exhaust flow to the side closer to the lower cover plate 12. The guide pipe 113 can change the direction of the exhaust gas introduced into the exhaust gas treatment tank 100 by the exhaust gas inlet pipe 111, increasing the effect of the exhaust gas carrying the waste gas neutralization liquid. This increases the mixing effect of the exhaust gas and the waste gas neutralization liquid. The guide pipe 113 makes the exhaust gas flow towards the side closer to the lower cover plate 12, making the flow path of the exhaust gas in the treatment tank longer and more tortuous, thereby increasing the residence time of the exhaust gas in the treatment tank. This allows the pollutants in the exhaust gas more time to chemically react with the neutralization liquid, which is conducive to more complete removal of harmful substances in the exhaust gas, improving the treatment effect, and making the final discharged gas more in line with environmental protection standards. Changing the flow direction of the exhaust gas can promote the mixing of the neutralization liquid and the exhaust gas at the microscopic level. When waste gas enters the neutralizing liquid at a specific angle, it generates stronger turbulence in localized areas, leading to more frequent contact between molecules in the neutralizing liquid and waste gas. This accelerates the chemical reaction, improves its thoroughness, and further reduces the residue of pollutants in the waste gas. Without the guide pipe 113, there might be dead zones within the treatment tank that are difficult for the airflow to reach, preventing the neutralizing liquid in these areas from fully contacting and reacting with the waste gas. The guide pipe 113, by changing the direction of the waste gas flow, effectively eliminates these dead zones, ensuring that every portion of the neutralizing liquid in the treatment tank participates in the waste gas treatment process, thus improving the effectiveness and stability of the entire treatment system.

[0024] In one implementation, a stirring assembly 15 is provided inside the treatment tank body 11. The stirring assembly 15 includes a stirring rod 151 fixed to the bottom of the treatment tank body 11 and a stirring fan 152 disposed at the end of the stirring rod 151 away from the treatment tank body 11. The distance between the stirring fan 152 and one side of the bottom of the treatment tank body 11 is greater than the distance between the air outlet of the guide pipe 113 and one side of the bottom of the treatment tank body 11. The exhaust gas introduced from the exhaust gas inlet pipe 111 can drive the stirring fan 152 to rotate through the guide pipe 113, thereby enabling the stirring fan 152 to mix the exhaust gas and neutralized liquid. This results in a more uniform mixture. The stirring fan 152 rotates under the drive of the exhaust gas, which can stir the exhaust gas and neutralized liquid from a vertical direction. This complements the flow of the neutralized liquid caused by the guide pipe 113 in a horizontal direction, achieving a multi-dimensional stirring effect. This ensures that the exhaust gas and neutralized liquid are fully mixed in all directions within the treatment tank, further improving the uniformity of the mixture and allowing the pollutants in the exhaust gas to fully contact and react with the neutralizing substances in the neutralized liquid. The rotation of the stirring fan 152 generates stronger shear forces and turbulence in localized areas, resulting in more thorough micro-mixing between the neutralizing liquid and the waste gas. This accelerates intermolecular diffusion and mass transfer, contributing to a more complete removal of harmful substances from the waste gas, improving treatment efficiency and quality, and making the waste gas treatment effect more stable and reliable. The stirring action of the stirring fan 152 on the neutralizing liquid continuously refreshes the contact interface between the waste gas and the neutralizing liquid, allowing the reaction to proceed continuously and efficiently. For pollutants with slower reaction rates, the stirring of the fan 152 can effectively shorten the reaction time, processing more waste gas in the same treatment time, or achieving the treatment target more quickly when treating the same amount of waste gas. This improves the overall treatment efficiency of the waste gas treatment system and helps meet the needs of large-scale, high-efficiency waste gas treatment. Utilizing the energy of the waste gas to drive the stirring fan 152 represents energy recovery and reuse, reducing the energy consumption such as electricity required by traditional stirring equipment and lowering the energy costs in the waste gas treatment process. The stable rotation of the stirring fan 152 ensures a continuous and stable stirring effect on the neutralizing liquid, unaffected by short-term fluctuations in factors such as exhaust gas flow rate and pressure. Even when the exhaust gas flow rate or composition changes, the stirring fan 152 can still maintain effective stirring of the neutralizing liquid through its own rotational inertia and the continuous action of the exhaust gas, making the exhaust gas treatment process more stable and the treatment effect more consistent. This is beneficial for ensuring the long-term stable operation of the exhaust gas treatment system and ensuring that the emitted exhaust gas always meets environmental protection standards.

[0025] As one implementation method, a diversion fan 114 capable of changing the gas flow direction is installed at the outlet of part of the exhaust gas inlet pipe 111 and the outlet of part of the guide pipe 113. When the guide pipe 113 discharges exhaust gas, it drives the diversion fan 114 to rotate. The rotation of the diversion fan 114 stirs and mixes the exhaust gas and the waste gas neutralization liquid on one hand, and changes the flow direction of the exhaust gas on the other hand. The diversion fan 114 is also used to change the flow direction of the exhaust gas, thereby making the flow direction of the exhaust gas in the waste gas neutralization liquid more chaotic, thus increasing the mixing effect of the exhaust gas and the waste gas neutralization liquid. When the diversion fan 114 rotates, it can stir the exhaust gas and the waste gas neutralization liquid from multiple angles, so that the exhaust gas comes into contact with the neutralization liquid in different directions. Compared with the effect of airflow in a single direction, it can greatly increase the dimensionality and uniformity of mixing, allowing the effective components in the exhaust gas and the neutralization liquid to come into more full contact and react, thereby improving the treatment effect. The diversion fan 114 changes the flow direction of the exhaust gas, making the flow direction of the exhaust gas in the waste gas neutralization liquid more chaotic, forming a stronger turbulent state. Turbulent flow increases the surface area and turnover rate of the gas-liquid interface, promoting the diffusion and mass transfer of pollutants in the waste gas into the neutralizing liquid, resulting in more thorough mixing and more complete removal of harmful substances from the waste gas. Because the diverter fan 114 ensures more uniform mixing and sufficient contact between the waste gas and the neutralizing liquid, the reaction rate between pollutants in the waste gas and the neutralizing liquid is accelerated, enabling the treatment process to be completed in a shorter time. This increases the waste gas treatment capacity per unit time, improves the overall treatment efficiency of the waste gas treatment system, and meets the enterprise's demand for efficient waste gas treatment. The diverter fan 114 can flexibly change the flow direction and stirring intensity of the waste gas by adjusting its angle, speed, and other parameters according to different waste gas flow rates, compositions, and treatment requirements. This allows the waste gas treatment system to better adapt to various complex operating conditions, improving system stability and reliability, and ensuring good treatment results under different circumstances.

[0026] As one implementation method, the exhaust gas inlet pipe 111 is located on the side of the exhaust gas treatment tank 100 near the center. Being closer to the center allows the exhaust gas to better agitate the neutralized liquid. The inlet of the exhaust gas inlet pipe 111 is equipped with an air compressor capable of compressing the exhaust gas. The air compressor increases the pressure of the exhaust gas, further enhancing the mixing effect between the exhaust gas and the neutralized liquid within the exhaust gas treatment tank 100. Positioning the exhaust gas inlet pipe 111 near the center allows the exhaust gas to enter from the center of the treatment tank, which, compared to entering from the edge, allows for more even diffusion in all directions. This better agitates the neutralized liquid throughout the treatment tank, preventing insufficient mixing in certain areas and improving the uniformity of the mixing between the exhaust gas and the neutralized liquid. This enhances the treatment effect and ensures that pollutants in the exhaust gas can fully contact and react with the effective components in the neutralized liquid over a wider area. The air compressor increases the pressure of the exhaust gas, allowing it to enter the treatment tank at a higher speed and with more energy. This enables the exhaust gas to impact and agitate the neutralizing liquid more forcefully, thereby greatly enhancing the mixing power of the exhaust gas and the neutralizing liquid. This allows the two to penetrate and mix more quickly and thoroughly, improving the mixing effect, accelerating the reaction rate, shortening the treatment time, and improving the overall efficiency of exhaust gas treatment.

[0027] In one implementation, the connection between the lower cover plate 12 and the treatment pool, the connection between the upper cover plate 13 and the lower cover plate 12, and the connection between the top cover plate 14 and the upper cover plate 13 are one of the following: bolt connection, screw-on bolt connection, snap-on connection, and tenon and mortise connection.

[0028] In one implementation, a filter screen is installed at the inlet of the exhaust gas inlet pipe 111. At least two gas concentration sensors and an alarm are installed inside the treatment tank body 11. The two gas concentration sensors are respectively located on the upper part of the adsorption cotton 121 and the upper part of the adsorption cake 131. The alarm is located on one side of the exterior of the treatment tank body 11 and is connected to the at least two gas concentration sensors. The filter screen effectively intercepts solid impurities and particulate matter in the exhaust gas, preventing these impurities from entering the treatment tank, avoiding pipe blockage, affecting gas flow, and damaging other components in the treatment tank such as gas concentration sensors and adsorption materials, thus ensuring the normal operation of the exhaust gas treatment system. The at least two gas concentration sensors, respectively located on the upper part of the adsorption cotton 121 and the upper part of the adsorption cake 131, can monitor the gas concentration at different locations in the treatment tank in real time, comprehensively understand the concentration changes of the exhaust gas during the treatment process, and provide accurate data support for judging the treatment effect and equipment operating status. When the gas concentration sensor detects an abnormal gas concentration, it can promptly transmit the signal to the alarm device. The alarm device then issues an alert, reminding staff to conduct timely inspections and handle the situation. This helps to promptly identify potential problems within the treatment tank, such as adsorption material failure, insufficient neutralization liquid, or pipeline leaks. This prevents the accumulation of problems from leading to a decline in treatment efficiency or equipment damage, ensuring the stable operation of the waste gas treatment system.
