Technical Field

[0001] This utility model relates to the field of waste gas treatment, and more specifically, to a low-resistance waste gas treatment shell structure. Background Technology

[0002] In industrial production, waste gas treatment is a crucial aspect of environmental protection and safe production, especially for industries such as chemical engineering, metallurgy, and spraying that generate high levels of dust and polluting gases. Therefore, there is an urgent need for efficient and low-energy-consumption waste gas purification equipment. While traditional waste gas treatment devices (such as cyclone dust collectors and electrostatic adsorption equipment) are widely used, most employ straight-through or simple flow-guiding structures, resulting in uneven airflow distribution, significant local turbulence, and large system pressure drops. For example, conventional intake structures, lacking airflow guidance, easily create eddies, increasing fan load and leading to persistently high operating energy consumption. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a low-resistance exhaust gas treatment shell structure, including a cylindrical body and an air inlet plate fixed at the top of the cylindrical body. A guide plate extending spirally towards the center of the air inlet plate is installed inside the air inlet plate, forming a spirally extending air inlet channel between the guide plate and the air inlet plate.

[0006] In a preferred embodiment, a through hole is provided at the center of the bottom end of the air intake plate, and the air intake channel and the guide pipe are connected through the through hole. A raised baffle is installed at the top edge of the through hole, and the baffle is arc-shaped with its two ends connected to the outer wall of the guide plate.

[0007] In a preferred embodiment, an intake pipe is installed on the outer wall of the intake disc, and the intake pipe is connected to the edge of the outer end of the guide plate.

[0008] In a preferred embodiment, a support frame is installed at the bottom of the air intake plate, the cylinder is located inside the support frame, and the distance between the base and the bottom end of the support frame is greater than the diameter of the base.

[0009] In a preferred embodiment, a plurality of slot plates are installed on the inner wall of the cylinder, and the slot plates have an insertion port on the side facing the flow guide column, and the electrostatic adsorption plate is inserted into the port.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. The spiral air intake channel of this utility model guides the exhaust gas to rotate through centrifugal force, reducing turbulence and local resistance, and significantly reducing the overall pressure inside the cylinder, thereby achieving a low resistance effect;

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] like Figure 1-3 The diagram shows a low-resistance exhaust gas treatment shell structure, including a cylindrical body 1 and an air intake plate 2 fixed to the top of the cylindrical body 1. Inside the air intake plate 2, a guide plate 3 extending spirally towards the middle of the air intake plate 2 is installed. A spirally extending air intake channel 4 is formed between the guide plate 3 and the air intake plate 2. A guide pipe 5 communicating with the air intake channel 4 is installed at the middle of the bottom end of the air intake plate 2. The guide pipe 5 penetrates downward through the cylindrical body 1 and extends into the interior of the cylindrical body 1. A detachable guide column 6 is installed inside the cylindrical body 1. Several equally spaced guide holes 7 penetrate the guide column 6. Several electrostatic adsorption plates 8 are installed between the outer wall of the guide column 6 and the inner wall of the cylindrical body 1. An exhaust pipe 9 is installed on the outer wall at the top of the cylindrical body 1.

[0020] An intake pipe 14 is installed on the outer wall of the intake disc 2, and the intake pipe 14 is connected to the edge of the outer end of the guide plate 3.

[0021] Based on the above, the exhaust gas enters the intake plate 2 through the outer intake pipe 14 and flows along the spiral intake channel 4 formed by the spiral guide plate 3.

[0022] The spiral air intake channel 4 guides the exhaust gas to rotate through centrifugal force, reducing turbulence and local resistance, and significantly reducing the overall pressure inside the cylinder 1, thereby achieving a low resistance effect.

[0023] A detachable base 10 is installed at the bottom end of the cylinder 1. Threads and grooves that engage with the threads are respectively provided at the edge of the base 10 and the edge of the bottom end of the cylinder 1. The base 10 is installed at the bottom end of the cylinder 1 through the threads and grooves.

[0024] A recessed flow guide shroud 11 is installed on the inner side of the base 10. The flow guide shroud 11 is arc-shaped and the opening faces upward. The bottom end of the flow guide tube 5 is located directly above the flow guide shroud 11.

[0025] Based on the above, the base 10 is connected to the cylinder 1 by threads, which facilitates disassembly and cleaning of deposited particles; the arc-shaped design of the flow guide shroud 11 optimizes the airflow direction and prevents particle accumulation.

[0026] The bottom center of the air intake plate 2 has a through hole 12. The air intake channel 4 and the guide pipe 5 are connected through the through hole 12. A protruding baffle 13 is installed at the top edge of the through hole 12. The baffle is arc-shaped and its two ends are respectively connected to the outer wall of the guide plate 3.

[0027] Based on the above, during the process of exhaust gas entering the guide pipe 5 from the spiral air intake channel 4 and through hole 12, particulate matter will accumulate. The baffle 13 is placed at the edge of the through hole 12, making it protrude a certain distance, which can prevent the accumulated matter from entering the interior of the guide pipe 5 under the force of airflow. At the same time, the baffle 13 structure can also prevent exhaust gas backflow, ensure that the airflow enters the guide pipe 5 in one direction, and improve the guide efficiency.

[0028] The bottom of the air intake plate 2 is equipped with a support frame 15, the cylinder 1 is located inside the support frame 15, the distance between the base 10 and the bottom of the support frame 15 is greater than the diameter of the base 10, and a number of slot plates 16 are installed on the inner wall of the cylinder 1. The slot plates 16 have an insertion port 17 on the side facing the guide column 6, and the electrostatic adsorption plate 8 is inserted into the insertion port 17.

[0029] Based on the above, the design of the detachable base 10 and the slot-type electrostatic adsorption plate 8 simplifies the cleaning and maintenance process, and the spacing between the support frame 15 and the base 10 avoids interference between components and facilitates operation.

[0030] Based on the above, during operation, the exhaust gas enters the intake plate 2 through the outer intake pipe 14 and flows along the spiral intake channel 4 formed by the spiral guide plate 3.

[0031] The spiral structure causes the exhaust gas to swirl, reducing the frictional resistance between the airflow and the channel wall, while improving the uniformity of airflow distribution. The exhaust gas enters the cylinder 1 vertically downward from the middle of the air inlet plate 2 through the guide pipe 5 and the through hole 12.

[0032] The end of the guide pipe 5 is located directly above the guide shroud 11. The arc design of the guide shroud 11 diffuses the exhaust gas in all directions, preventing the airflow from directly impacting the bottom of the cylinder 1. Inside the cylinder 1, there is a guide column 6 with multiple guide holes 7, which further disperses the airflow, reduces the flow velocity, and prolongs the residence time of the exhaust gas in the cylinder 1. After passing through the guide column 6, the exhaust gas enters the area between the guide column 6 and the inner wall of the cylinder 1.

[0033] The electrostatic adsorption plate 8 installed here adsorbs particulate matter (such as dust and oil mist) in the exhaust gas through a high-voltage electric field, thereby achieving purification. The purified gas flows upward and is discharged through the exhaust pipe 9 at the top of the cylinder 1.

[0034] Furthermore, in this application, the spiral intake channel 4 and the guide hole 7 of the guide column 6 work together to optimize the airflow distribution and reduce energy loss. The cooperation between the guide shroud 11 and the guide pipe 5 avoids airflow impact and further reduces system pressure.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
