Description

Technical Field

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

[0002] In the tin plating process, waste gas generation mainly originates from several key stages, involving multiple mechanisms such as chemical reactions, physical processes, and energy exchange. The primary source of waste gas in the tin plating process is the high-temperature volatilization of organic waste gas during the acidic immersion tin plating process. Tin plating solutions typically contain strong acids such as sulfuric acid and hydrochloric acid, which release acid mist when heated or reacting with the substrate. These gases are irritating to the respiratory system, causing symptoms such as sore throat and cough, and corrode surrounding equipment, resulting in pollution when released into the atmosphere. Although existing technologies have developed waste gas scrubbing systems, the types of waste gas vary between workshops. To treat different types of waste gas, each workshop typically uses a single, fixed waste gas scrubbing device. In actual production, the content of waste gas is often quite complex, and treatment with only a single spray solution is inefficient. Furthermore, installing multiple scrubbing devices in each workshop is costly. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a waste gas treatment system that can efficiently and flexibly treat waste gas generated by multiple production workshops. This system has the advantages of small footprint, low investment and high waste gas treatment efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Provide exhaust gas treatment systems, including:

[0006] The collection module is used to collect waste gas from each production workshop;

[0007] The collection module is used to collect the waste gas from each workshop.

[0008] A spray module, connected to the collection module, is used to spray and neutralize the waste gas input into the collection module. The spray module includes several reactors, each interconnected by pipes, and each pipe is equipped with a first solenoid valve.

[0009] The spray module generates spray liquid to spray and neutralize the waste gas. Since each reactor is interconnected by pipes and each pipe is equipped with a first solenoid valve, each reactor is connected to the remaining reactors. Therefore, by controlling the first solenoid valve, the connected reactors can be flexibly adjusted, that is, the order in which the waste gas passes through the reactors can be flexibly adjusted, so that the mixed waste gas can be treated by different spray liquids, achieving a highly efficient waste gas treatment effect.

[0010] The collection module includes a main pipeline, which collects waste gas from corresponding workshops through several first branch pipelines. The main pipeline is connected to corresponding reactors through several second branch pipelines. Each first branch pipeline is equipped with a second solenoid valve, and each second branch pipeline is equipped with a third solenoid valve.

[0011] Because of the main pipeline and branch pipelines, the workshop exhaust gas can be input into the reactor through the main pipeline. By controlling the third solenoid valve on the second branch pipeline, the reactor into which the exhaust gas enters can be flexibly selected, so as to achieve the effect of flexible neutralization reaction.

[0012] The first solenoid valve, the second solenoid valve, and the third solenoid valve are respectively connected to a controller. The controller controls the opening sequence of the solenoid valves according to the type of exhaust gas to control the flow of exhaust gas through the reactor.

[0013] The controller can intelligently adjust the opening sequence of the first, second, and third solenoid valves. In practical applications, the controller can flexibly control the opening state of the corresponding solenoid valves simply by inputting the specific type of exhaust gas, demonstrating a high degree of intelligence.

[0014] In some embodiments, an emission module is also included, which is connected to the spray module and is used to emit the gas after the reaction. The emission module is equipped with a gas concentration detection alarm.

[0015] The emission module is equipped with a gas concentration detection alarm, which can detect various waste gases in the exhaust gas. Only when all waste gas components meet the standards will the gas be discharged. In practical applications, multiple required gas concentration detection alarms are installed to accurately detect the corresponding waste gas concentrations.

[0016] In some embodiments, a waste liquid recovery module is also included, which is connected to the bottom of the reactor.

[0017] The waste liquid recovery module is used to recover the spray liquid, so that the spray liquid containing waste gas can be treated before being discharged.

[0018] In some embodiments, the reactor includes a spray head and several packing layers, the spray head being located at the top of the reactor and the packing layers being distributed from top to bottom along the height of the reactor.

[0019] Because the spray heads are located at the top, the exhaust gas that can be transported from bottom to top can be sprayed more effectively, and the packing layer further enhances the treatment of the exhaust gas.

[0020] In some embodiments, environmentally friendly balls are placed on the filler layer.

[0021] In some embodiments, the top of the reactor is provided with a fog deflector, through which the exhaust gas treated by the packing layer is discharged.

[0022] The defogging panel allows the treated exhaust gas containing water vapor to have the water vapor removed before it is discharged.

[0023] In some embodiments, the discharge module includes a circulation tank and a wastewater treatment tank, which are respectively connected to the bottom of the reactor. The circulation tank is used to receive secondary scrubbing liquid after treating the waste gas, and the secondary scrubbing liquid is returned to the spray head.

[0024] The circulation tank is used to reuse the spray liquid that can still be used for spraying. In practical applications, the state of the spray liquid at the bottom of the reactor is detected to determine whether to continue recycling. When it cannot be recycled, the wastewater treatment tank at the bottom of the reactor is opened to transfer the waste liquid to the wastewater treatment tank.

[0025] The wastewater treatment tank includes a neutralization unit, a sedimentation unit, and a filtration unit arranged sequentially along the wastewater flow direction.

[0026] The neutralization unit is used to neutralize the treated wastewater again, thereby achieving the effect of wastewater recycling.

[0027] In the sedimentation unit, the wastewater that produces precipitate after the neutralization reaction undergoes a sedimentation reaction.

[0028] The filtration unit filters the wastewater that produces sediment, removing impurities.

[0029] In some embodiments, the spray head is a dual-head spray head that rotates.

[0030] Dual-head nozzles produce a better spraying effect.

[0031] In some embodiments, the reactor is also equipped with a pH meter, a flow meter, and a pressure gauge.

[0032] pH meter, flow meter and pressure gauge are used to detect the pH, flow rate and pressure of the spray liquid, respectively, and the state of the spray liquid is adjusted in time when it does not meet the requirements.

[0033] In some embodiments, the spray module further includes a liquid tank, which is fed into the spray module via a self-priming gas-liquid mixing pump.

[0034] The beneficial effects of the waste gas treatment system of this utility model:

[0035] This utility model discloses a waste gas treatment system. Its collection module collects waste gas from the corresponding workshop via a first branch pipe and transmits it to the main pipe. The main pipe then transmits the waste gas to the corresponding reactor via a second branch pipe. Because a second solenoid valve, a third solenoid valve, and a first solenoid valve are respectively installed between the first branch pipe, the second branch pipe, and each reactor, the order of waste gas transmission from each workshop to the corresponding reactor and the flow reactor can be arbitrarily adjusted. When multiple workshops have different types of waste gas and need to treat waste gas simultaneously, the waste gas from each workshop can be uniformly converged into the main pipe. Subsequently, by controlling the opening sequence of the first solenoid valves in each reactor, the mixed waste gas can be treated in a controlled manner. The waste gas is sequentially introduced into different reactors and treated by corresponding spray liquids, ensuring that the final output waste gas can be efficiently neutralized. This eliminates the need for multiple reactors in each workshop, saving costs and allowing for flexible adjustment of the corresponding reactors, thus improving production efficiency. Furthermore, when only one type of waste gas is generated in a production workshop and only that workshop's waste gas needs to be treated, simply opening the corresponding second and third solenoid valves is sufficient to transfer the waste gas to the appropriate reactor for neutralization. Moreover, when different types of waste gas are generated in a workshop, simply adjusting the third solenoid valve is enough to transfer the waste gas to the appropriate reactor, effectively reducing treatment costs.

[0046] Example 1

[0047] For the exhaust gas treatment system disclosed in this embodiment, please refer to [link / reference needed]. Figures 1-5 ,include:

[0048] The collection module is used to collect waste gas from each production workshop 14;

[0049] The collection module is used to collect the exhaust gas from each workshop, and it is generally collected through equipment such as air hoods and air inlets.

[0050] A spray module, connected to the collection module, is used to spray and neutralize the waste gas input into the collection module. The spray module includes several reactors 1, each reactor 1 is interconnected by pipes, and each pipe is equipped with a first solenoid valve 2.

[0051] The spray module generates spray liquid to spray and neutralize the waste gas. Since each reactor 1 is interconnected by pipes and each pipe is equipped with a first solenoid valve 2, each reactor 1 is connected to the remaining reactors 1, and each connected pipe is equipped with a first solenoid valve 2. Therefore, by controlling the first solenoid valve 2, the connected reactors 1 can be flexibly adjusted, that is, the order in which the waste gas passes through the reactors 1 can be flexibly adjusted, so that the mixed waste gas can be treated by different spray liquids, achieving a highly efficient waste gas treatment effect.

[0052] The spray module is mainly used to capture and neutralize acidic gases, organic solvent vapors, and other harmful gases. It uses a chemical solution, such as an alkaline liquid (e.g., sodium hydroxide solution), to react with the acidic gases in the exhaust gas, converting them into harmless or weaker compounds, thereby achieving the purpose of exhaust gas purification.

[0053] The collection module includes a main pipeline 3, which collects waste gas from corresponding workshops through several first branch pipelines 4. The main pipeline is connected to corresponding reactors 1 through several second branch pipelines 5. Each first branch pipeline 4 is equipped with a second solenoid valve 6, and each second branch pipeline 5 is equipped with a third solenoid valve 7.

[0054] Because of the main pipeline 3 and branch pipelines, the workshop exhaust gas can be input into reactor 1 through the main pipeline 3. The third solenoid valve 7 on the second branch pipeline can be controlled to flexibly select the reactor 1 into which the exhaust gas enters, so as to achieve the effect of flexible neutralization reaction.

[0055] The first solenoid valve 2, the second solenoid valve 6, and the third solenoid valve 7 are respectively connected to the controller. The controller controls the opening sequence of the solenoid valves according to the type of waste gas in order to control the flow of waste gas through the reactor 1.

[0056] The controller can intelligently adjust the opening sequence of the first solenoid valve 2, the second solenoid valve 6, and the third solenoid valve 7. In practical applications, as long as the specific type of exhaust gas is input, the controller can flexibly control the opening state of the corresponding solenoid valves, which has the advantage of high intelligence.

[0057] That is, the collection module is responsible for collecting the waste gas in each production workshop 14, and using equipment such as air collection hoods and air intakes for centralized collection.

[0058] It includes a main pipeline 3, which collects the waste gas of the corresponding workshop through several first branch pipelines 4, and connects to the corresponding reactor 1 through several second branch pipelines 5 respectively.

[0059] Each first branch pipe 4 is equipped with a second solenoid valve 6, and each second branch pipe 5 is equipped with a third solenoid valve 7. These solenoid valves are connected to the controller, and the controller controls the opening sequence of the solenoid valves according to the type of exhaust gas.

[0060] The spray module is connected to the collection module and is used to neutralize the exhaust gas input to the collection module through spraying. It includes several reactors 1, which are interconnected by pipes, and each pipe is equipped with a first solenoid valve 2.

[0061] The spray module generates spray liquid to neutralize the waste gas. By controlling the first solenoid valve 2, the order in which the waste gas passes through the reactor 1 can be flexibly adjusted, so that the mixed waste gas can be treated by different spray liquids, achieving a highly efficient waste gas treatment effect.

[0062] Main uses: Capturing and neutralizing acidic gases, organic solvent vapors, and other harmful gases. It utilizes a chemical solution (such as sodium hydroxide (NaOH)) to react with acidic gases in waste gas, converting them into harmless or weaker compounds.

[0063] The opening sequence of the first solenoid valve 2, the second solenoid valve 6, and the third solenoid valve 7 is intelligently adjusted.

[0064] By simply inputting the specific type of exhaust gas, the controller can flexibly control the opening state of the corresponding solenoid valves, achieving intelligent control. This system is designed to allow for precise control of the exhaust gas treatment process, adapting to the treatment needs of different types of exhaust gases and improving treatment efficiency and effectiveness. Through the intelligent control system, the treatment process can be automatically adjusted according to the specific composition of the exhaust gas, achieving more flexible and efficient exhaust gas treatment.

[0065] In this embodiment, an emission module is also included. The emission module is connected to the spray module and is used to emit the gas after the reaction. The emission module is equipped with a gas concentration detection alarm.

[0066] The emission module is equipped with a gas concentration detection alarm to monitor various waste gases and ensure that emissions are only released when all components meet the standards. In practical applications, multiple gas concentration detection alarms are installed to accurately detect the corresponding waste gas concentrations. The waste gas flows upward and comes into full contact with the descending spray liquid (chemical solution). Acidic gases (such as HCl, SO2, NOx, etc.) react with the alkaline solution, undergoing a neutralization reaction to form corresponding salt compounds.

[0067] Right now,

[0068] A gas concentration detection alarm is installed to detect the concentration of various pollutants in the exhaust gas. This ensures that the exhaust gas meets environmental standards before emission, avoiding environmental pollution. It can detect various pollutants in the exhaust gas, including but not limited to acidic gases (such as HCl, SO2, NOx, etc.). When the detected pollutant concentration exceeds a set safety threshold, the alarm will sound, prompting operators to take appropriate measures. In practical applications, multiple gas concentration detection alarms may be installed to ensure accurate detection of the corresponding exhaust gas concentration. The exhaust gas flows upward, making full contact with the descending spray liquid (chemical solution) to ensure that the pollutants in the exhaust gas react fully with the solution. Acidic gases (such as HCl, SO2, NOx, etc.) in the exhaust gas undergo a neutralization reaction with alkaline solutions (such as sodium hydroxide NaOH solution). The neutralization reaction produces corresponding salt compounds, which are generally more stable than the original acidic gases and have less environmental impact.

[0069] This design not only ensures the efficiency and effectiveness of waste gas treatment but also improves the system's safety and environmental friendliness. Through intelligent control and precise detection, the entire system can flexibly respond to different waste gas treatment needs, achieving efficient, safe, and environmentally friendly waste gas treatment.

[0070] The treated gas should be tested before being released to confirm that all its indicators meet the emission standards stipulated by the local environmental protection department.

[0071] Gases that meet the standards are discharged into the atmosphere through chimneys or pipes, while gases that do not meet the standards need to be returned for treatment or subjected to other treatment methods for further purification.

[0072] In this embodiment, a waste liquid recovery module is also included, which is connected to the bottom of the reactor 1.

[0073] The waste liquid recovery module is used to recover the spray liquid, so that the spray liquid containing waste gas can be treated before being discharged.

[0074] In this embodiment, the reactor 1 includes a spray head 8 and several packing layers 9. The spray head 8 is located at the top of the reactor 1, and the several packing layers 9 are distributed from top to bottom along the height direction of the reactor 1.

[0075] Since the spray head 8 is located at the top, the exhaust gas that can be transported from bottom to top can be sprayed better, and the packing layer 9 can better treat the exhaust gas.

[0076] Right now,

[0077] The packing layer 9 is distributed from top to bottom along the height direction of the reactor 1 and fills the inside of the reactor 1 to increase the surface area and time of contact between the waste gas and the spray liquid, thereby improving the treatment efficiency.

[0078] The spray head 8 evenly sprays the spray liquid into the interior of the reactor 1, ensuring full contact between the waste gas and the spray liquid. Even spraying improves the reaction efficiency between the waste gas and the spray liquid, promoting the neutralization reaction.

[0079] The packing layer 9 provides additional surface area, allowing more contact between the exhaust gas and the spray liquid, thereby improving treatment efficiency.

[0080] The presence of packing layer 9 extends the residence time of exhaust gas inside reactor 1, which helps to make the neutralization reaction more thorough.

[0081] The design of the packing layer 9 promotes sufficient contact between gas and liquid, improves mass transfer efficiency, and allows pollutants in the exhaust gas to be more effectively absorbed and neutralized by the spray liquid. The exhaust gas enters from the bottom of reactor 1 and flows upwards. The rising exhaust gas comes into contact with the spray liquid sprayed from the top spray head 8, initiating a neutralization reaction. As the exhaust gas passes through the packing layer 9, it further contacts and reacts with the spray liquid; the design of the packing layer 9 helps to improve the efficiency of this process.

[0082] Reactor 1 can treat waste gas more effectively, ensuring that pollutants in the waste gas are removed to the maximum extent, thereby meeting environmental emission standards. This design not only improves the efficiency of waste gas treatment but also enhances the system's processing capacity, enabling it to adapt to different operating conditions and changes in waste gas composition.

[0083] The mixed gas that has undergone the initial reaction will pass through the packing layer 9, further increasing the gas-liquid contact area and improving the reaction efficiency.

[0084] In this embodiment, environmentally friendly balls are placed on the filler layer 9.

[0085] In this embodiment, the top of the reactor 1 is provided with a fog-proof plate, and the exhaust gas treated by the packing layer 9 is discharged through the fog-proof plate.

[0086] Defogging panels allow treated exhaust gases containing moisture to have the moisture removed before being discharged. In other words, defogging panels intercept small droplets carried by the gas, preventing them from being discharged with the gas and ensuring clean outlet gas.

[0087] In this embodiment, the emission module includes a circulation tank 10 and a wastewater treatment tank. The circulation tank 10 and the wastewater treatment tank are respectively connected to the bottom of the reactor 1. The circulation tank 10 is used to receive the secondary scrubbing liquid after treating the waste gas, and the secondary scrubbing liquid flows back to the spray head 8.

[0088] The circulation tank 10 is used to reuse the spray liquid that can still be used for spraying. In actual application, the state of the spray liquid at the bottom of the reactor 1 is detected to determine whether to continue to circulate it. When it cannot be circulated, the wastewater treatment tank at the bottom of the reactor 1 is opened to transfer the waste liquid to the wastewater treatment tank.

[0089] The wastewater treatment tank includes a neutralization unit 11, a sedimentation unit 12, and a filtration unit 13 arranged sequentially along the wastewater flow direction.

[0090] Neutralization unit 11 is used to perform a second neutralization reaction on the treated wastewater to achieve the effect of wastewater recycling.

[0091] In sedimentation unit 12, the wastewater that produces precipitate after the neutralization reaction undergoes a sedimentation reaction.

[0092] The filtration unit 13 filters the wastewater that produces sediment to remove impurities.

[0093] Saturated or expired alkaline solutions need to be sent to a wastewater treatment pond for neutralization, sedimentation, filtration and other treatments before being discharged or recycled.

[0094] Right now,

[0095] The circulation tank 10 is connected to the bottom of the reactor 1 and is used to receive the secondary scrubbing liquid after the waste gas treatment. The wastewater treatment tank is also connected to the bottom of the reactor 1 and is used to treat waste liquid that cannot be recycled. When the scrubbing liquid cannot be recycled, the waste liquid is transferred to the wastewater treatment tank.

[0096] Neutralization unit 11 performs a second neutralization reaction on the treated wastewater to achieve the effect of wastewater recycling.

[0097] The sedimentation unit 12 performs a sedimentation reaction on the wastewater that has precipitated after the neutralization reaction.

[0098] The filtration unit 13 filters the wastewater that produces sediment to remove impurities.

[0099] Wastewater treatment process: Wastewater first enters neutralization unit 11 for a neutralization reaction, adjusting the pH value and reducing the corrosiveness and toxicity of the wastewater. After neutralization, the wastewater enters sedimentation unit 12 to precipitate the solid substances generated in the reaction. The precipitated wastewater then enters filtration unit 13 to further remove suspended solids and impurities, improving the clarity of the wastewater.

[0100] Wastewater that has undergone neutralization, sedimentation, and filtration can be directly discharged into the environment if it meets discharge standards. If the treated wastewater still has some value, it can be recycled and reused.

[0101] In this embodiment, the spray head 8 is a dual-head spray head, and the dual-head spray head 8 rotates.

[0102] The dual-head nozzles can produce a better spraying effect. Multiple spray heads 8 located at the top of the tower spray the pre-prepared alkaline solution downwards evenly, forming dense alkaline droplets.

[0103] In this embodiment, the reactor 1 is also equipped with a pH meter, a flow meter and a pressure gauge.

[0104] pH meters, flow meters, and pressure gauges are used to detect the pH, flow rate, and pressure of the spray solution, respectively. When these parameters do not meet requirements, the spray solution's condition is adjusted promptly. Regularly measuring parameters such as pH, flow rate, and pressure of the spray solution monitors the effectiveness of the entire treatment process, and adjusting the alkali concentration and flow rate according to actual needs.

[0105] In this embodiment, the spray module further includes a liquid tank 15, which is fed into the spray module via a self-priming gas-liquid mixing pump.

[0106] Regularly inspect and maintain or replace components such as pumps, nozzles, packing, and demisters to ensure proper equipment operation.

[0107] The above-mentioned waste gas treatment devices can effectively purify tin plating waste gas, reduce environmental harm, reduce corrosion of surrounding equipment, and reduce occupational health risks for workers.

[0108] The aforementioned waste gas treatment system uses a fluoroplastic horizontal water pump to pump wastewater and a fiberglass variable frequency centrifugal fan to discharge the treated gas. The entire system is connected by pipes welded together, with an inspection port and observation window above reactor 1. The pipes are PPR pipes, and a self-priming gas-liquid mixing pump delivers alkaline solution to the reaction tank and then to spray head 8. The alkaline solution reacts chemically with the acidic gases in the waste gas, converting them into harmless or weaker compounds. The purified gas is then discharged into the air by the fiberglass variable frequency centrifugal fan.

[0109] For example, the reaction chamber body is composed of a 2000x2000mm cylinder, with spray heads 8 connected internally via pipes. 400x400mm air inlets and outlets are provided on both sides, a 300mm diameter observation window is provided at the front, a 1000mm diameter maintenance port is provided at the top, and a DN80 reflux port is provided at the bottom of the reaction chamber. The reagent tank is located next to the reactor 1, and is supplied to the spray heads 8 via a DN40 PPR pipe and a self-priming gas-liquid mixing pump. An 11KW fiberglass variable frequency centrifugal fan is connected via a flange flexible connector.

[0110] For ease of use, the FRP variable frequency centrifugal fan, self-priming gas-liquid mixing pump, and solenoid valves are controlled by an electrical box. The electrical box area is divided into an indicator light area, a frequency converter display area, and a switch area.
