Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and particularly discloses a green environmental protection catalytic combustion line. Background Art

[0002] In activities such as industrial production, waste gas treatment and resource utilization are crucial. There are many problems with traditional waste gas treatment methods. In the past, most waste gas treatment equipment used a single treatment method, such as simple filtration or adsorption, which was difficult to deal with complex waste gas components and different working conditions. It was difficult to recycle the adsorbent after use, resulting in increased costs and waste of resources. At the same time, there was a lack of effective design for energy utilization, and the heat generated by catalytic combustion was wasted, resulting in high energy consumption.

[0003] In terms of gas and wastewater emissions, traditional treatment technologies are difficult to effectively reduce the degree of environmental pollution. Waste gas often contains a large amount of harmful substances and is directly discharged into the atmosphere, affecting air quality; wastewater is discharged without sufficient treatment, threatening the water environment. Moreover, traditional catalytic combustion equipment lacks sufficient safety guarantee measures. There are potential safety hazards such as fires and explosions during operation, affecting the stable operation of the equipment and the safety of operators. In view of this, an efficient, low-energy, green environmental protection and safe and stable catalytic combustion line is needed to solve these problems. Content of the Utility Model

[0004] In order to overcome the deficiencies existing in the prior art, the purpose of the utility model is to provide a green environmental protection catalytic combustion line.

[0005] To achieve the above purpose, a green environmental protection catalytic combustion line of the utility model includes an adsorption box, a main fan, an emitter, and a first pipeline for connecting the three. The adsorbent in the adsorption box is used to adsorb harmful substances in the external waste gas. The gas treated by the adsorption box enters the emitter through the first pipeline driven by the wind force of the main fan and is discharged; it also includes a catalytic combustor, a desorption fan, a second pipeline, and a third pipeline. The second pipeline is used to connect the catalytic combustor, the desorption fan, and the adsorption box, and the third pipeline is used to connect the desorption fan and the emitter; after the adsorbent in the adsorption box is saturated with adsorption, the adsorption box is desorbed driven by the wind force of the desorption fan, and the desorbed waste gas enters the catalytic combustor through the second pipeline for catalytic combustion. The gas purified by catalytic combustion enters the emitter through the third pipeline for discharge.

[0006] The adsorbent in the adsorption box can effectively adsorb harmful substances in the external waste gas, preliminarily purify the waste gas, and provide a good basis for subsequent emissions. When the adsorbent is saturated with adsorption, the desorbed waste gas is introduced into the catalytic combustor through a desorption fan for catalytic combustion, which can completely decompose the harmful substances in the waste gas and achieve efficient purification. The adsorbent can be reused during the adsorption process. After desorption when it is saturated with adsorption, the desorbed adsorbent can be used for adsorption again, realizing the recycling of resources and reducing costs.

[0007] Furthermore, a second valve is provided on the second pipeline between the catalytic combustor and the desorption fan. The second valve is connected to the external air to regulate the air pressure in the pipeline. A flame arrester is provided on one side of the catalytic combustor to prevent the propagation of flames in the pipeline.

[0008] The second valve is connected to the external air to regulate the air pressure in the pipeline, which can ensure the pressure stability during the operation of the entire system. At the same time, the second valve can also be used to supply fresh air to the pipeline to adjust the gas environment in the pipeline and ensure the stability of the gas pressure and temperature in the pipeline. The stable pressure helps to improve the efficiency of each link such as adsorption, desorption, and catalytic combustion, making the waste gas treatment more complete, reducing the emission of incompletely treated waste gas, and thus achieving the purpose of green environmental protection. The setting of the flame arrester can effectively prevent the propagation of flames in the pipeline, reducing the risks of fire and explosion. This not only ensures the safe operation of the system but also avoids the release of harmful gases and pollutants caused by fire or explosion, playing a role in protecting the environment.

[0009] Furthermore, a first valve is provided on the first pipeline connecting the adsorption box and the main fan. An air filter is provided inside the first valve. The air filter is composed of multiple layers of filter meshes. The gas treated by the adsorption box enters the emitter after being filtered by the filter meshes.

[0010] The setting of the air filter can further filter the gas treated by the adsorption box, remove possible remaining fine particles, impurities, etc., ensure that the emitted gas is cleaner, reduce the pollution to the atmospheric environment, and meet the requirements of green environmental protection. The multiple layers of filter meshes can provide a more efficient filtering effect, perform hierarchical filtering on pollutants of different sizes, and improve the filtering accuracy and reliability. The filter meshes can prevent impurities from entering the main fan, reduce the wear and failure risks of the main fan, and extend the service life of the main fan. Different waste gas sources may contain different types and concentrations of pollutants, and the air filter can be adjusted and replaced according to the actual situation to adapt to different waste gas treatment requirements.

[0011] Further, the emitter is set as a chimney, which includes a base and a chimney body. One side of the chimney body is connected to the third pipe, and the other side of the chimney body is provided with a fourth pipe. A water collector is provided on the fourth pipe, and the water collector is connected to the chimney body through the fourth pipe; the wastewater generated by catalytic combustion in the catalytic combustor flows into the water collector through the third pipe and the fourth pipe.

[0012] By setting the water collector, the wastewater generated by catalytic combustion in the catalytic combustor can be centrally collected, avoiding environmental pollution caused by the random discharge of wastewater. Centralized treatment of wastewater can improve treatment efficiency and reduce treatment costs, meeting the requirements of green environmental protection. The water collector is connected to the chimney body through the fourth pipe to ensure that the wastewater can flow smoothly into the water collector. As an emitter, the chimney discharges the treated gas into the atmosphere. The presence of the water collector can prevent the wastewater from being discharged into the atmosphere along with the gas, avoiding secondary pollution.

[0013] Further, a heat preservation layer is sleeved on the second pipe connecting the adsorption box and the catalytic combustor. The heat preservation layer is composed of a heat preservation medium and is used to store the desorption heat generated by catalytic combustion so that the waste gas entering the catalytic combustor can be preheated.

[0014] The heat preservation layer can store the desorption heat generated by catalytic combustion, preheating the waste gas entering the catalytic combustor. This can reduce the additional energy input required during the catalytic combustion of the waste gas and improve energy utilization efficiency. The preheated waste gas is more likely to reach the reaction temperature of catalytic combustion, which can accelerate the catalytic reaction speed and improve the efficiency of catalytic combustion.

[0015] Further, the water collector includes a housing, a water collection chamber and a filter layer. The filter layer is composed of a filtering medium, and the wastewater generated by catalytic combustion flows into the water collection chamber after being filtered by the filtering medium.

[0016] The setting of the filter layer can filter the wastewater generated by catalytic combustion, removing pollutants such as impurities and particulate matter in the wastewater, and preliminarily purifying the wastewater. This helps to reduce the pollution of wastewater to the environment, meeting the requirements of green environmental protection. The filtering medium can be selected according to the characteristics of the wastewater to improve the filtering effect. For example, a filtering medium with adsorption properties can be selected to remove harmful substances in the wastewater. The filtered wastewater can be stored in the water collection chamber for further treatment and recycling. This can reduce the demand for fresh water resources and reduce water resource waste.

[0017] Further, the green environmental protection combustion line further includes a dry filter box. The dry filter box includes a filter box body, a filter unit provided on the filter box body and a maintenance door. An exhaust gas valve is provided on one side of the dry filter box for inputting external exhaust gas, and the other side of the dry filter box is connected to the first pipe for inputting the filtered gas into the adsorption box.

[0018] The dry filter box can preliminarily filter the external waste gas, removing large particle impurities, dust and other substances in the waste gas. This helps to reduce the processing burden of subsequent equipment such as the adsorption box, improving the processing efficiency and stability of the entire system. The waste gas treated by the dry filter box is cleaner, which is conducive to the better adsorption effect of the adsorbent in the adsorption box, improving the adsorption efficiency of harmful substances. The setting of the inspection door facilitates the regular inspection and maintenance of the dry filter box by the staff. The accumulated substances on the filter unit can be cleaned in time to ensure that the filtering effect is always good.

[0019] Furthermore, the number of adsorption boxes is set to be multiple. The multiple adsorption boxes are connected through the first pipeline, and the multiple adsorption boxes are respectively connected to the desorption fan and the catalytic combustor through the second pipeline; at least one adsorption box among the multiple adsorption boxes maintains the adsorption operation.

[0020] The setting of multiple adsorption boxes increases the capacity and speed of waste gas treatment. More waste gas can be treated simultaneously, improving the processing efficiency of the entire system. The multiple adsorption boxes are connected through pipelines, which can realize the diversion and parallel processing of waste gas, further improving the processing efficiency. At least one adsorption box among the multiple adsorption boxes maintains the adsorption operation, ensuring the continuous operation of the system. When one of the adsorption boxes is saturated with adsorption and needs to be desorbed, the other adsorption boxes can continue the adsorption treatment without interrupting the waste gas treatment process. The multiple adsorption boxes can be flexibly configured and scheduled according to actual needs. The working state of the adsorption box can be adjusted according to parameters such as the flow rate and concentration of the waste gas to achieve the optimal utilization of resources.

[0021] Furthermore, the main fan includes a fan body and a driving motor. A first gear is provided on the output shaft of the driving motor, a fan shaft is provided on the fan body, and a fan blade and a second gear adapted to the first gear are respectively provided at both ends of the fan shaft. Belts are sleeved outside the first gear and the second gear to achieve power transmission.

[0022] Through the combined transmission method of gears and belts, the power of the driving motor can be efficiently transmitted to the fan body, making the fan blade rotate at a suitable speed. The efficient transmission can improve the working efficiency of the main fan, ensuring that the waste gas can flow quickly and stably in the system, thereby improving the processing efficiency of the entire waste gas treatment system. The reasonably designed transmission system can reduce the energy consumption of the driving motor. By optimizing the cooperation of gears and belts, energy loss can be reduced and the energy utilization efficiency can be improved. This helps to reduce the operating cost of the entire waste gas treatment system and also meets the energy-saving requirements of green environmental protection.

[0023] Furthermore, the structure of the desorption fan is the same as that of the main fan.

[0024] Like the main blower, the desorption blower can also achieve stable operation and appropriate air volume control through an efficient transmission system, ensuring the efficient progress of the desorption process. This helps to improve the desorption efficiency, reduce energy consumption, and meet the requirements of green environmental protection. The desorption blower has the same structure as the main blower, making the equipment more standardized during manufacturing, installation, and maintenance. This can reduce production costs, improve production efficiency, and also facilitate the storage and replacement of parts.

[0025] The beneficial effects of the present utility model: high efficiency and low energy consumption. The structural design of the dry filter box, multiple adsorption boxes, catalytic combustor, and blower, as well as the setting of the heat insulation layer, can better achieve the flexible adjustment of the catalytic combustion line for different working states, improve the treatment efficiency. The adsorbent in the adsorption box can be recycled after desorption, and the heat generated by catalytic combustion can be recycled through the heat insulation layer, realizing the recycling of resources and reducing energy consumption; green environmental protection. The setting of the catalytic combustor, air filter, and water collector can make the pollutants in the gas and water discharged by the catalytic combustion line lower, and better meet the requirements of green environmental protection; safe and stable. The setting of the flame arrester and pressure relief valve can well achieve the safe and stable operation during the working process of the catalytic combustion line.

Detailed implementation manners

[0032] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present utility model.

[0033] Please refer to Figures 1 to 5 As shown in the figure, a green environmental protection catalytic combustion line of the present utility model includes an adsorption box 2, a main fan 4, a discharger 6, and a first pipeline 21 for connecting the three. The adsorbent in the adsorption box 2 is used to adsorb harmful substances in the external waste gas. The gas processed by the adsorption box 2 is driven by the wind force of the main fan 4 and enters the discharger 6 through the first pipeline 21 for discharge. It further includes a catalytic combustor 3, a desorption fan 5, a second pipeline 22, and a third pipeline 61. The second pipeline 22 is used to connect the catalytic combustor 3, the desorption fan 5, and the adsorption box 2. The third pipeline 61 is used to connect the desorption fan 5 and the discharger 6. After the adsorbent in the adsorption box 2 is saturated with adsorption, the adsorption box 2 is driven by the wind force of the desorption fan 5 for desorption. The desorbed waste gas enters the catalytic combustor 3 through the second pipeline 22 for catalytic combustion, and the gas purified by catalytic combustion enters the discharger 6 through the third pipeline 61 for discharge.

[0034] During actual use, the adsorbent in the adsorption box 2 can effectively adsorb harmful substances in the external waste gas, and perform preliminary purification treatment on the waste gas, providing a good basis for subsequent discharge. When the adsorbent is saturated with adsorption, the desorbed waste gas is introduced into the catalytic combustor 3 through the desorption fan 5 for catalytic combustion, which can completely decompose the harmful substances in the waste gas and achieve efficient purification. The adsorbent can be reused during the adsorption process. When it is saturated with adsorption, desorption is carried out, and the desorbed adsorbent can be used for adsorption again, realizing the recycling of resources and reducing costs.

[0035] Specifically, a second valve 221 is provided on the second pipeline 22 between the catalytic combustor 3 and the desorption fan 5. The second valve 221 is connected to the outside air for adjusting the air pressure in the pipeline. A flame arrester 31 is provided on one side of the catalytic combustor 3 to prevent the spread of flames in the pipeline.

[0036] In actual use, the second valve 221 is connected to the outside air for adjusting the air pressure in the pipeline, which can ensure the pressure stability during the operation of the entire system. At the same time, the second valve 221 can also be used to supplement fresh air into the pipeline to adjust the gas environment in the pipeline and ensure the stability of the gas pressure and temperature in the pipeline. The stable pressure helps to improve the efficiency of each link such as adsorption, desorption, and catalytic combustion, making the waste gas treatment more complete, reducing the emission of incompletely treated waste gas, and thus achieving the purpose of green environmental protection. The setting of the flame arrester 31 can effectively prevent the spread of flames in the pipeline, reducing the risk of fire and explosion. This not only ensures the safe operation of the system but also avoids the release of harmful gases and pollutants caused by fire or explosion, playing a role in protecting the environment.

[0037] Specifically, a first valve 211 is provided on the first pipeline 21 connecting the adsorption box 2 and the main fan 4. An air filter 212 is provided inside the first valve 211. The air filter 212 is composed of multiple filter meshes 2121. The gas treated by the adsorption box 2 enters the discharger 6 for discharge after being filtered by the filter meshes 2121.

[0038] In actual use, the setting of the air filter 212 can further filter the gas treated by the adsorption box 2, removing possible residual fine particles, impurities, etc., ensuring that the discharged gas is cleaner, reducing the pollution of the atmospheric environment, and meeting the requirements of green environmental protection. The multiple filter meshes 2121 can provide a more efficient filtering effect, performing hierarchical filtering for pollutants of different sizes, improving the filtering accuracy and reliability. The filter meshes 2121 can prevent impurities from entering the main fan 4, reducing the wear and failure risk of the main fan 4 and extending the service life of the main fan 4. Different waste gas sources may contain different types and concentrations of pollutants, and the air filter 212 can be adjusted and replaced according to the actual situation to adapt to different waste gas treatment requirements.

[0039] Specifically, the discharger 6 is set as a chimney 60. The chimney 60 includes a base 601 and a chimney body 602. One side of the chimney body 602 is connected to a third pipeline 61, and a fourth pipeline 62 is provided on the other side of the chimney body 602. A water collector is provided on the fourth pipeline 62, and the water collector is connected to the chimney body 602 through the fourth pipeline 62; the wastewater generated by catalytic combustion in the catalytic combustor 3 flows into the water collector through the third pipeline 61 and the fourth pipeline 62.

[0040] In actual use, by setting up a water collector, the wastewater generated by catalytic combustion in the catalytic combustor 3 can be centrally collected, preventing the random discharge of wastewater from polluting the environment. Centralized treatment of wastewater can improve treatment efficiency and reduce treatment costs, meeting the requirements of green environmental protection. The water collector is connected to the chimney body 602 through the fourth pipeline 62 to ensure that the wastewater can flow smoothly into the water collector. The chimney 60 serves as the emitter 6 to discharge the treated gas into the atmosphere. The presence of the water collector can prevent wastewater from entering the atmosphere along with the gas discharge, avoiding secondary pollution.

[0041] Specifically, a heat preservation layer 222 is sleeved on the second pipeline 22 connecting the adsorption box 2 and the catalytic combustor 3. The heat preservation layer 222 is composed of a heat preservation medium and is used to store the desorption heat generated by catalytic combustion so that the waste gas entering the catalytic combustor 3 can be preheated.

[0042] In actual use, the heat preservation layer 222 can store the desorption heat generated by catalytic combustion, preheating the waste gas entering the catalytic combustor 3. This can reduce the additional energy input required during the catalytic combustion of the waste gas and improve energy utilization efficiency. The preheated waste gas is more likely to reach the reaction temperature of catalytic combustion, which can accelerate the catalytic reaction rate and improve the efficiency of catalytic combustion.

[0043] Specifically, the water collector includes a housing 71, a water collection chamber 72, and a filter layer 73. The filter layer 73 is composed of a filtering medium, and the wastewater generated by catalytic combustion flows into the water collection chamber 72 after being filtered by the filtering medium.

[0044] In actual use, the filter layer 73 can filter the wastewater generated by catalytic combustion, removing pollutants such as impurities and particulate matter in the wastewater, and preliminarily purifying the wastewater. This helps reduce the pollution of the wastewater to the environment and meets the requirements of green environmental protection. The filtering medium can be selected according to the characteristics of the wastewater to improve the filtering effect. For example, a filtering medium with adsorption properties can be selected to remove harmful substances in the wastewater. The filtered wastewater can be stored in the water collection chamber 72 for further treatment and recycling. This can reduce the demand for fresh water resources and reduce water resource waste.

[0045] Specifically, the green environmental protection combustion line further includes a dry filtering box 1. The dry filtering box 1 includes a filtering box body 12, a filtering unit 13 provided on the filtering box body 12, and a maintenance door 14. An exhaust gas valve 11 is provided on one side of the dry filtering box 1 for inputting external exhaust gas, and the other side of the dry filtering box 1 is connected to the first pipeline 21 for inputting the filtered gas into the adsorption box 2.

[0046] In actual use, the dry filter box 1 can preliminarily filter the external waste gas, removing large particle impurities, dust and other substances in the waste gas. This helps to reduce the treatment burden of subsequent equipment such as the adsorption box 2, and improve the treatment efficiency and stability of the entire system. The waste gas treated by the dry filter box 1 is cleaner, which is beneficial to the better adsorption effect of the adsorbent in the adsorption box 2 and improves the adsorption efficiency of harmful substances. The setting of the inspection door 14 facilitates the staff to regularly inspect and maintain the dry filter box 1. The accumulated substances on the filter unit 13 can be cleaned in time to ensure that the filtering effect is always good.

[0047] Specifically, the number of adsorption boxes 2 is set to be multiple, and the multiple adsorption boxes 2 are connected through the first pipeline 21. The multiple adsorption boxes 2 are respectively connected to the desorption fan 5 and the catalytic combustor 3 through the second pipeline 22; at least one adsorption box 2 among the multiple adsorption boxes 2 is maintained to perform the adsorption work.

[0048] In actual use, the setting of multiple adsorption boxes 2 increases the capacity and speed of waste gas treatment. More waste gas can be treated simultaneously, improving the treatment efficiency of the entire system. The multiple adsorption boxes 2 are connected through pipelines, which can realize the diversion and parallel processing of waste gas, further improving the treatment efficiency. At least one adsorption box 2 among the multiple adsorption boxes 2 is maintained to perform the adsorption work, ensuring the continuous operation of the system. When one of the adsorption boxes 2 is saturated with adsorption and needs to be desorbed, the other adsorption boxes 2 can continue to perform the adsorption treatment without interrupting the waste gas treatment process. The multiple adsorption boxes 2 can be flexibly configured and scheduled according to actual needs. The working state of the adsorption box 2 can be adjusted according to parameters such as the flow rate and concentration of the waste gas to achieve the optimal utilization of resources.

[0049] Specifically, the main fan 4 includes a fan main body 41 and a driving motor 42. A first gear 43 is provided on the output shaft of the driving motor 42. A fan shaft 44 is provided on the fan main body 41. A fan blade 45 and a second gear 46 adapted to the first gear 43 are respectively provided at both ends of the fan shaft 44. A belt 47 is sleeved outside the first gear 43 and outside the second gear 46 to achieve power transmission.

[0050] In actual use, through the combined transmission method of gears and the belt 47, the power of the driving motor 42 can be efficiently transmitted to the fan main body 41, enabling the fan blade 45 to rotate at a suitable speed. The efficient transmission can improve the working efficiency of the main fan 4, ensuring that the waste gas can flow quickly and stably in the system, thereby improving the treatment efficiency of the entire waste gas treatment system. The reasonably designed transmission system can reduce the energy consumption of the driving motor 42. By optimizing the cooperation of the gears and the belt 47, the energy loss can be reduced and the energy utilization efficiency can be improved. This helps to reduce the operating cost of the entire waste gas treatment system and also meets the energy-saving requirements of green environmental protection.

[0051] Specifically, the structure of the desorption fan 5 is the same as that of the main fan 4.

[0052] In actual use, like the main fan 4, the desorption fan 5 can also achieve stable operation and appropriate air volume control through an efficient transmission system, ensuring the efficient progress of the desorption process. This helps to improve the desorption efficiency, reduce energy consumption, and meet the requirements of green environmental protection. The desorption fan 5 and the main fan 4 having the same structure makes the equipment more standardized during manufacturing, installation, and maintenance. This can reduce production costs, improve production efficiency, and also facilitate the storage and replacement of parts.
