Description

Technical Field

[0001] This utility model belongs to the field of industrial waste gas treatment technology, and in particular relates to an environmentally friendly treatment device for exhaust gas from aluminum profile spraying. Background Technology

[0002] Spray coating is a common surface treatment technology used to coat the surface of aluminum profiles with a protective or decorative coating. Aluminum profile spray coating exhaust gas refers to the waste gas generated during the curing process of the coating after powder coating of aluminum profiles. This process produces volatile organic compounds (such as benzene, toluene, xylene, etc.), particulate matter, smoke, and other harmful gases. If these exhaust gases are directly emitted into the atmosphere, they will pollute the environment, affect air quality, and pose potential hazards to human health. Therefore, it is necessary to effectively treat aluminum profile spray coating exhaust gas to reduce pollutant emissions and protect the environment and human health.

[0003] In simple terms, during the treatment of exhaust gas from aluminum profile spraying, the exhaust gas enters the adsorption tower through a pipeline for spraying to remove large particulate solids. Subsequently, the treated gas enters a dry filter and an activated carbon adsorption filter in sequence before being discharged into the air.

[0004] However, in existing adsorption towers, some components (such as nozzles and swirl plates) are fixedly installed. During the process of exhaust gas entering the adsorption tower, if the nozzles are unevenly distributed in the tower or are blocked by impurities or solid particles in the exhaust gas, some areas will be sprayed excessively while other areas will be sprayed insufficiently, resulting in inadequate exhaust gas treatment. Therefore, an environmentally friendly treatment device for exhaust gas from aluminum profile spraying is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide an environmentally friendly treatment device for exhaust gas from aluminum profile spraying, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An environmentally friendly treatment device for exhaust gas from aluminum profile spraying, comprising:

The multiple swirl plates are circumferentially distributed with the axial direction of the support column as the center, and the ends of the multiple swirl plates away from the rotating toothed ring are rotatably connected to the support column. The outer wall of the rotating toothed ring meshes with the inner wall of the upper end of the rotating cylinder. The rotating cylinder is rotatably installed inside the outer shell.

[0009] A filtration structure is provided, which is connected to the outer casing pipe.

[0010] In a further technical solution, the spray treatment structure also includes pulleys, a transmission belt, and a motor. The outer housing has a mounting groove for accommodating the transmission belt.

[0011] In a further technical solution, the outer casing has a rotating groove inside, and the upper end outer wall of the rotating cylinder is rotatably mounted in the rotating groove.

[0012] In a further technical solution, the cross-section of the rotating cylinder is set as an isosceles trapezoid, the cross-sectional diameter of the upper end of the rotating cylinder is larger than the cross-sectional diameter of the lower end, and the outer wall of the rotating cylinder has multiple uniformly distributed through holes.

[0013] In a further technical solution, the spray treatment structure also includes nozzles. The outer shell has a fixing ring and connecting pipes inside. Multiple connecting pipes are provided and installed on the inner wall of the fixing ring.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides an environmentally friendly treatment device for exhaust gas from aluminum profile spraying, comprising:

[0026] The spray treatment structure 1 includes an outer shell 11, a support column 12, a toothed ring 13, a swirl plate 14, and a rotating cylinder 15. The support column 12 is vertically installed inside the outer shell 11 and is coaxial with the outer shell 11. Multiple swirl plates 14 are provided and are obliquely installed on the inner wall of the toothed ring 13. The multiple swirl plates 14 are circumferentially distributed with the axis of the support column 12 as the center, and the ends of the multiple swirl plates 14 away from the toothed ring 13 are rotatably connected to the support column 12. The outer wall of the toothed ring 13 meshes with the inner wall of the upper end of the rotating cylinder 15. The rotating cylinder 15 is rotatably installed inside the outer shell 11.

[0027] Filter processing structure 2 is connected to the outer shell 11 by a pipe;

[0028] In this embodiment, the rotating drum 15 rotates axially around the support column 12; the rotating drum 15 drives the toothed ring 13 and the swirl plate 14 in the toothed ring 13 to also rotate axially around the support column 12; the rotating swirl plate 14 uses centrifugal force to separate solid or liquid particles in the exhaust gas, thereby achieving high treatment efficiency; at the same time, the rotating swirl plate 14 generates strong rotation and turbulence in the tower, and the clean water sprayed from the nozzle 19 is more evenly distributed inside the outer shell 11 by the swirl plate 14, increasing the contact area and contact time between the exhaust gas and the clean water, thereby improving the adsorption and dissolution efficiency of pollutants;

[0029] Specifically, the spray treatment structure 1 also includes pulleys 16, a drive belt 17, and a motor 18. The outer housing 11 has a mounting groove 111 for accommodating the drive belt 17. A pair of pulleys 16 are provided, one of which is mounted on the lower end face of the rotating drum 15, and the other pulley 16 is rotatably mounted on the outside of the outer housing 11. The drive belt 17 is connected to the pair of pulleys 16 via the mounting groove 111. The output shaft of the motor 18 is connected to the pulley 16 mounted on the outside of the outer housing 11.

[0030] In this embodiment, after starting, the motor 18 drives the pulley 16 outside the outer casing 11 to rotate. Through the transmission belt 17, the pulley 16 installed on the lower end face of the rotating drum 15 also rotates synchronously, thereby driving the rotating drum 15 to rotate axially around the support column 12. The rotating drum 15 drives the toothed ring 13 and the swirl plate 14 in the toothed ring 13 to rotate axially around the support column 12. The operation is simple, no manual operation is required, and the automation level of the equipment is improved.

[0031] Specifically, the outer casing 11 has a rotating groove 112 inside, and the upper end outer wall of the rotating cylinder 15 is rotatably mounted in the rotating groove 112;

[0032] Specifically, the cross-section of the rotating cylinder 15 is set as an isosceles trapezoid, the cross-sectional diameter of the upper end of the rotating cylinder 15 is larger than the cross-sectional diameter of the lower end, and the outer wall of the rotating cylinder 15 has a plurality of uniformly distributed through holes 151.

[0033] In this embodiment, the exhaust gas flows through the swirl plate 14 to the through hole 151 and enters the filter treatment structure 2 through the pipe for filtration treatment. During this process, the solid particles and impurities in the exhaust gas are further filtered by the rotating drum 15 and finally discharged into the air.

[0034] Specifically, the spray treatment structure 1 also includes nozzles 19. The outer shell 11 has a fixing ring 113 and a connecting pipe 114 inside. Multiple connecting pipes 114 are provided and installed on the inner wall of the fixing ring 113. The multiple connecting pipes 114 are circumferentially distributed with the support column 12 as the center. Multiple sets of nozzles 19 are provided, and multiple nozzles 19 are provided in each set. The multiple nozzles 19 are installed at intervals on the connecting pipes 114. The fixing ring 113 is placed at a predetermined distance above the toothed ring 13.

[0035] In this embodiment, the water pump delivers clean water from the water tank to the connecting pipe 114 and sprays it into the outer housing 11 through the nozzle 19;

[0036] Specifically, the outer housing 11 also has a filter plate 115, which is disposed at a predetermined distance above the fixing ring 113;

[0037] In this embodiment, the spray exhaust gas to be treated enters the interior of the outer housing 11 from the upper end of the outer housing 11 through a pipe, first passes through the filter plate 115, and then flows towards the lower end of the outer housing 11.

[0038] The working principle of this utility model is as follows:

[0039] The exhaust gas to be treated enters the outer housing 11 from the upper end through the pipe, passes through the filter plate 115 first, and then flows towards the lower end of the outer housing 11. At this time, the water pump sends clean water from the water tank to the connecting pipe 114 and sprays it into the outer housing 11 through the nozzle 19.

[0040] After starting, the motor 18 drives the pulley 16 outside the outer casing 11 to rotate. Through the transmission belt 17, the pulley 16 installed on the lower end face of the rotating drum 15 also rotates synchronously, thereby driving the rotating drum 15 to rotate axially around the support column 12. The rotating drum 15 drives the toothed ring 13 and the swirl plate 14 in the toothed ring 13 to rotate axially around the support column 12. The operation is simple and does not require manual operation by workers, thus improving the automation level of the equipment.

[0041] In this way, the rotating swirl plate 14 uses centrifugal force to separate solid or liquid particles in the exhaust gas, thereby achieving high treatment efficiency. At the same time, the rotating swirl plate 14 generates strong rotation and turbulence in the tower, and the clean water sprayed from the nozzle 19 is more evenly distributed inside the outer shell 11 by the swirl plate 14, increasing the contact area and contact time between the exhaust gas and the clean water, thereby improving the adsorption and dissolution efficiency of pollutants.

[0042] Subsequently, the exhaust gas flows through the swirl plate 14 to the through hole 151 and enters the filtration structure 2 through the pipe for filtration. During this process, solid particles and impurities in the exhaust gas are further filtered by the rotating drum 15 and finally discharged into the air.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
