Description

Technical Field

[0001] This utility model relates to the technical field of waste gas purification treatment devices, and in particular to a high-efficiency adsorption device for purifying waste gas from a calcining furnace. Background Technology

[0002] The core function of calcining furnace exhaust gas treatment is to purify the harmful gases and particulate matter generated during the calcination process, ensuring that exhaust gas emissions comply with environmental regulations and standards, thereby effectively protecting the environment and safeguarding public health. At the same time, it achieves waste heat recovery and resource recycling, ultimately achieving a win-win situation for both the economy and the environment.

[0003] On the one hand, traditional devices lack effective multi-stage synergistic purification and pre-protection mechanisms, leading to easy clogging and insufficient deep treatment; on the other hand, their airflow distribution design is poor, resulting in low utilization rate and insufficient contact of activated carbon adsorption materials. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a high-efficiency adsorption device for purifying calcining furnace exhaust gas. First, the spray box effectively removes large particulate impurities from the exhaust gas, preventing them from clogging the subsequent honeycomb metal catalyst and activated carbon adsorption plates, ensuring the stable operation of the core purification unit. Next, the combination of ultraviolet light and the catalyst efficiently inactivates microorganisms and decomposes some organic pollutants. Finally, the activated carbon adsorption layer specifically targets residual odors, organic gases, and fine particulate matter for deep purification. Simultaneously, multiple sets of air outlets in the air guide box allow the exhaust gas to be evenly distributed and fully flow through the gaps between the activated carbon adsorption plates, significantly increasing the effective contact area and contact time between the exhaust gas and the activated carbon. This combination of multi-stage synergistic treatment and optimized airflow distribution design greatly improves the adsorption utilization rate of activated carbon and the overall purification efficiency of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-efficiency adsorption device for purifying exhaust gas from a calcining furnace includes: a base and a disinfection chamber. A spray chamber is fixedly connected to the top of the base. A second air guide pipe passes through one side of the spray chamber. One side of the second air guide pipe passes through the outer wall of the disinfection chamber. A disinfection component is installed inside the disinfection chamber. An adsorption chamber is fixedly connected to the top of the disinfection chamber. An installation strip is fixedly connected to the inside of the adsorption chamber. An adsorption component is installed inside the installation strip.

[0007] Furthermore, the disinfection assembly includes multiple disinfection lamps fixedly connected inside the disinfection chamber, the disinfection lamps being arranged in three equidistant groups, and two honeycomb-shaped metal catalysts installed inside the disinfection chamber, the honeycomb-shaped metal catalysts being disposed between the disinfection lamps.

[0008] Furthermore, the adsorption assembly includes a mounting plate slidably connected inside the mounting strip, and activated carbon adsorption membranes are installed on both sides of the outer wall of the mounting plate.

[0009] Furthermore, an air guide box is fixedly connected inside the adsorption box, and multiple sets of air outlets are opened on one side of the air guide box.

[0010] Furthermore, a water pump body is installed on the top of the spray box, and multiple water pipes are installed on the outer wall of the water pump body. Multiple nozzles are installed inside the spray box, and the nozzles are connected to the water pump body through water pipes. An air inlet is opened on one side of the spray box, and a drain outlet is opened at the bottom of the spray box.

[0011] Furthermore, a first air guide tube is provided on one side of the disinfection box, and the disinfection box is connected to the air guide box through the first air guide tube.

[0012] Furthermore, the outer wall of the adsorption box is rotatably connected to a door.

[0013] Furthermore, the top of the adsorption box is provided with multiple exhaust ports.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the spray box first removes large particulate impurities to prevent them from clogging the honeycomb metal catalyst and activated carbon adsorption membrane, thereby improving purification efficiency. Then, the combination of ultraviolet light and catalyst effectively destroys microorganisms and decomposes some organic pollutants. Finally, the activated carbon adsorption layer is specifically designed to deeply purify residual odors, organic gases and fine particulate matter, achieving a highly efficient purification effect.

[0016] 2. In this utility model, the design of multiple sets of air outlets in the air guide box allows the exhaust gas to be evenly distributed and fully flow through the gaps between each layer of activated carbon adsorption membrane, increasing the effective contact area and contact time between the exhaust gas and the activated carbon, thereby significantly improving the adsorption utilization rate of the activated carbon and the final purification effect.

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.

[0025] Reference Figures 1-5 This utility model provides an embodiment of a high-efficiency adsorption device for purifying calcining furnace exhaust gas, comprising: a base 1 and a disinfection chamber 7. A spray chamber 2 is fixedly connected to the top of the base 1. A second air guide pipe 10 passes through one side of the spray chamber 2, and one side of the second air guide pipe 10 passes through the outer wall of the disinfection chamber 7. A disinfection component is installed inside the disinfection chamber 7. An adsorption chamber 6 is fixedly connected to the top of the disinfection chamber 7. An installation strip 20 is fixedly connected inside the adsorption chamber 6, and an adsorption component is installed inside the installation strip 20. The top of the spray box 2 is equipped with a water pump body 3. Multiple water pipes 4 pass through the outer wall of the water pump body 3. Multiple nozzles 15 are installed inside the spray box 2. The nozzles 15 are connected to the water pump body 3 through the water pipes 4. An air inlet 11 is opened on one side of the spray box 2. A drain outlet 16 is opened at the bottom of the spray box 2. A first air guide pipe 8 passes through one side of the disinfection box 7. The disinfection box 7 is connected to the air guide box 13 through the first air guide pipe 8. A door 9 is rotatably connected to the outer wall of the adsorption box 6. Multiple exhaust ports 5 pass through the top of the adsorption box 6.

[0026] Specifically, the exhaust gas enters the spray chamber 2 through the inlet 11 and is sprayed by the nozzles 15 to remove large particulate impurities and prevent clogging of subsequent units. The pre-treated exhaust gas enters the disinfection chamber 7 through the second air guide pipe 10, where it is efficiently inactivated by alternating disinfection lamps 14 and honeycomb metal catalysts 17, and VOCs are decomposed. The purified exhaust gas is introduced into the air guide box 13 in the adsorption chamber 6 through the first air guide pipe 8, where the exhaust gas is evenly dispersed through the outlet 19, allowing it to flow fully through the gaps between the activated carbon adsorption membranes 18 on the mounting strips 20, greatly increasing the contact area and time, and achieving deep adsorption. Finally, the purified gas is discharged through the exhaust port 5. The airflow distribution of the air guide box 13 is optimized, which significantly improves the utilization rate of activated carbon and the purification efficiency, while avoiding clogging of the core unit.

[0027] Reference Figure 1 and Figure 4 Multiple disinfection lamps 14 are fixedly connected inside the disinfection chamber 7. The disinfection lamps 14 are arranged in three groups at equal intervals. Two honeycomb metal catalysts 17 are installed inside the disinfection chamber 7 and are arranged between the disinfection lamps 14.

[0028] Specifically, the exhaust gas is introduced into the interior of the disinfection chamber 7 through three second air guide pipes 10. Inside the chamber, it is first disinfected by the disinfection lamp 14, then the pollutants inside are removed by the honeycomb metal catalyst 17, and then it is disinfected again by the disinfection lamp 14. The multi-stage alternating combination achieves efficient disinfection.

[0029] Reference Figure 1 and Figure 5 The mounting strip 20 is internally slidably connected to the mounting plate 12. Activated carbon adsorption membranes 18 are installed on both sides of the outer wall of the mounting plate 12. An air guide box 13 is fixedly connected inside the adsorption box 6. Multiple sets of air outlet holes 19 are opened on one side of the air guide box 13.

[0030] Specifically, the exhaust gas is discharged into the activated carbon adsorption membrane 18 through the exhaust hole 19 opened in the air guide box 13, which increases the effective contact area and contact time between the exhaust gas and the activated carbon, thereby greatly improving the adsorption utilization rate of the activated carbon and the final purification effect, and then discharged from the exhaust port 5 at the top.

[0031] Working principle: Waste gas enters the spray chamber 2 through the inlet 11 and is sprayed by the nozzles 15 driven by the water pump body 3 to remove large particulate impurities; after pretreatment, the waste gas enters the disinfection chamber 7 through the second air guide pipe 10, and achieves multi-stage ultraviolet catalytic reaction through the alternating disinfection lamps 14 and honeycomb metal catalysts 17, which efficiently inactivates microorganisms and decomposes VOCs; the purified gas is introduced into the air guide box 13 in the adsorption chamber 6 through the first air guide pipe 8, and is evenly dispersed through its air outlet 19, so that the waste gas can fully flow through the gaps between the activated carbon adsorption membranes 18 on the mounting strip 20, greatly increasing the contact area and time; finally, the deeply purified gas is discharged from the exhaust port 5.
