Description

Technical Field

[0001] This utility model relates to the field of printing exhaust gas technology, specifically to an environmentally friendly treatment device for printing exhaust gas. Background Technology

[0002] In the printing industry, processes such as ink mixing, printing, and drying generate a large amount of waste gas containing volatile organic compounds (VOCs). If this waste gas is discharged directly without effective treatment, it will not only cause serious pollution to the atmospheric environment, causing environmental problems such as smog and photochemical smog, but also harm human health, leading to respiratory diseases, nervous system damage, and so on.

[0003] Currently, spray treatment technology is a commonly used method for treating printing waste gas. Traditional spray treatment devices mostly use fixed nozzles, and the water mist sprayed from the nozzles is umbrella-shaped. The waste gas mainly flows vertically upward in the tower and can only come into contact with the water mist directly below the nozzle. The coverage area of ​​the umbrella-shaped water mist is limited, resulting in a short gas-liquid contact time, making it difficult to effectively capture fine particulate matter and non-water-soluble VOCs in the waste gas.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly waste gas treatment device for printing to solve the problems mentioned in the background art.

[0008] Furthermore, a fixing rod is fixedly installed on the side wall of the connecting rod, and the bottom of the fixing rod is fixedly connected to the side wall of the arc-shaped guide plate;

[0009] The inner wall of the arc-shaped guide plate is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to the outer wall of the ball shaft;

[0010] A water storage valve is fixedly installed at the bottom of the support rod, and the bottom of the water storage valve is fixedly connected to the center of the top of the spray head. The inner wall of the bottom of the connecting rod is interconnected with the connecting pipe, the support rod, the arc-shaped guide plate, and the inner wall of the spray head.

[0011] Furthermore, the outer wall of the protective box is provided with an inspection window, and a transparent isolation door is rotatably installed on the inner wall of the inspection window.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The rotating and swinging components drive the entire spray assembly to rotate in a circular motion. The spray head moves along a spiral trajectory under the constraint of the arc-shaped guide plate. The water mist diffuses in a conical spiral. The vortex increases the contact area of ​​the water mist, which increases the collision frequency between the exhaust gas and the water mist. The spiral motion of the water mist and the rising airflow of the exhaust gas form a reverse shear force, causing the exhaust gas to follow a spiral upward path in the tower, thus prolonging the residence time of the exhaust gas.

[0017] 2. During the diffusion process, the spiral water mist forms more tiny water droplets, which greatly increases the specific surface area of ​​the water mist. This gives volatile organic compounds, dust and other pollutants in the exhaust gas more attachment points, enabling them to be absorbed and captured more effectively, thereby improving the purification effect on pollutants.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1-4This utility model provides a technical solution: an environmentally friendly treatment device for waste gas from printing, including a protective box 1. A rotating swing assembly 6 is fixedly installed on the inner wall of the protective box 1. After the rotating motor 601 in the rotating swing assembly 6 is started, the drive gear 602 fixedly installed at its bottom drive end begins to rotate. Since the outer wall of the drive gear 602 is meshed with the driven gear 603, the driven gear 603 will rotate accordingly. A connecting rod 610 is fixedly installed at the end of the driven gear 603, and a follower gear 604 is fixedly installed at the end of the connecting rod 610, so the follower gear 604 will rotate accordingly. Since the bottom end of the outer wall of the follower gear 604 is meshed with the rotating gear 605, the rotating gear 605 also begins to rotate. Finally, the spray assembly 7 fixed at the bottom of the rotating gear 605 performs a circular rotational motion. The spray assembly 7 includes components fixedly installed at the bottom of the rotating gear 605. The unit has a connecting pipe 701, with a support rod 702 fixedly installed at the bottom of the connecting pipe 701. A spray head 704 is fixedly installed at the bottom of the support rod 702. A ball shaft 707 is fixedly installed on the outer wall of the spray head 704. An arc-shaped guide plate 703 is slidably installed on the outer wall of the ball shaft 707. A support assembly 3 is fixedly installed on the side end of the arc-shaped guide plate 703. During the rotation of the spray assembly 7, due to the fixed arc-shaped guide plate 703, the rotation of the connecting pipe 701 drives the support rod 702 and the spray head 704 to move. The ball shaft 707 slides and rotates in the groove 705 of the arc-shaped guide plate 703, causing the spray head 704 to tilt and rotate around the ball shaft 707 as the axis. This makes the water mist appear in a spiral shape, increasing the contact area and contact time between the exhaust gas and the water mist, thereby improving the capture effect of fine particulate matter and non-water-soluble VOCs in the exhaust gas and effectively improving the quality of exhaust gas treatment.

[0025] Please see Figure 2 This utility model provides a technical solution: an environmentally friendly treatment device for waste gas from printing, including a swing motor 607 fixedly installed on the inner wall of a protective box 1. After the swing motor 607 is started, its drive end drives a fixedly installed swing gear 608 to rotate reciprocally. Since the swing gear 608 meshes with the swing gear 609 connected to the outer wall, it drives the swing gear 609 to rotate. The swing sleeve 606 fixedly installed on the inner wall of the swing gear 609 swings along with the swing gear 609. The connecting rod 301 fixedly installed on the outer wall of the swing sleeve 606 is rotatably connected to the top of the rotating gear 605 at its bottom. Driven by the swing sleeve 606, the connecting rod 301 drives the rotating gear 605 and the spray assembly 7 fixedly installed at its bottom to swing at a certain angle. Combined with the circumferential rotation of the spray assembly 7 driven by the rotating motor 601, the spray assembly 7 achieves a composite motion mode combining rotation and swing.

[0026] Please see Figure 2This utility model provides a technical solution: an environmentally friendly treatment device for waste gas from printing, including a connecting rod 301 with a fixing rod 302 fixedly installed on its side wall. This installation method of the fixing rod 302 allows it to connect the arc-shaped guide plate 703 to the connecting rod 301, effectively limiting the position of the arc-shaped guide plate 703. During the movement of the spray assembly 7, it prevents the arc-shaped guide plate 703 from shifting or shaking, ensuring its stability. The arc-shaped guide plate 703 provides a precise track for the sliding of the ball shaft 707 on the outer wall of the spray head 704. After the fixing rod 302 firmly fixes the arc-shaped guide plate 703, it can ensure that the ball shaft 707 always slides and rotates along a predetermined path within the groove 705 of the arc-shaped guide plate 703.

[0027] Please see Figure 2 This utility model provides a technical solution: an environmentally friendly treatment device for waste gas from printing, including a water pipe 5 fixedly installed on the inner wall of the top of the connecting rod 301 near the fixed rod 302. The inner wall of the water inlet 4 fixedly installed on the top of the water pipe 5 adopts a threaded connection design. In the actual installation process, the operator only needs to align the water outlet of the water supply device with the water inlet 4 and then rotate and tighten it to achieve a quick and stable connection. The threaded connection itself has good sealing performance. When the water supply device is tightened with the water inlet 4, the engagement between the threads can effectively prevent water leakage and ensure the stable operation of the water supply system.

[0028] Please see Figure 3 , Figure 4 This utility model provides a technical solution: an environmental protection device for treating waste gas from printing, including an arc-shaped guide plate 703 with a groove 705 on its inner wall, and a ball shaft 707 installed on the outer wall of a spray head 704. The inner wall of the groove 705 is slidably connected to the outer wall of the ball shaft 707. When the ball shaft 707 slides in the groove 705, it can drive the spray head 704 to tilt and rotate along a predetermined trajectory.

[0029] Please see Figure 3This utility model provides a technical solution: an environmentally friendly treatment device for printing waste gas, including a water storage valve 706 fixedly installed at the bottom of a support rod 702. The water storage valve 706 is located between the support rod 702 and a spray head 704, and its bottom is fixedly connected to the center of the top of the spray head 704. It plays a key role in regulating and distributing the absorbent liquid, allowing the absorbent liquid to be evenly buffered and distributed before entering the spray head 704, avoiding uneven liquid flow or pressure fluctuations that could affect the amount of liquid sprayed from each nozzle of the spray head 704. The inconsistency improves the uniformity of the absorbent spray and enhances the waste gas treatment effect. The inner wall of the bottom of the connecting rod 301 is interconnected with the inner wall of the connecting pipe 701, the support rod 702, the arc-shaped guide plate 703, and the spray head 704. This interconnected structure forms a complete liquid transport channel, which ensures that the absorbent flows smoothly from the connecting rod 301 into the connecting pipe 701, and then enters the spray head 704 through the support rod 702 and the water storage valve 706, providing a stable supply of absorbent to the spray head 704 and ensuring the continuous operation of the spraying.

[0030] Please see Figure 1 This utility model provides a technical solution: an environmental protection treatment device for waste gas from printing, including a protective box 1 with a specially opened inspection window 2 on the outer wall, and a transparent isolation door rotatably installed on the inner wall of the inspection window 2. During the operation of the equipment protected by the protective box 1, the staff can directly observe the operation status of the internal equipment through the inspection window 2 and the transparent isolation door without opening the protective box 1.

[0031] Working principle: When the rotary motor 601 is started, its driving end drives the drive gear 602 to rotate. Since the drive gear 602 is meshed with the outer wall of the driven gear 603, the driven gear 603 will rotate accordingly. A connecting rod 610 is fixedly installed at the end of the driven gear 603, and a follower gear 604 is fixedly installed at the end of the connecting rod 610. The follower gear 604 will rotate together with the driven gear 603. A rotating gear 605 is meshed with the bottom of the outer wall of the follower gear 604. Driven by the follower gear 604, the rotating gear 605 starts to rotate, which in turn drives the spray assembly 7 fixedly installed at its bottom to rotate.

[0032] Since the arc-shaped guide plate 703 is fixed, the rotation of the connecting pipe 701 will drive the support rod 702 and the spray head 704 to move, so that the ball shaft 707 slides and rotates on the inner wall of the groove 705 opened on the inner wall of the arc-shaped guide plate 703, thereby causing the spray head 704 to tilt and rotate about the ball shaft 707 as the axis, thus expanding the spray range.

[0033] Simultaneously, the swing motor 607 is started, and its drive end drives the swing gear 608 to rotate reciprocally. The swing gear 608 meshes with the outer wall of the swing gear 609, thereby driving the swing gear 609 to rotate. A swing sleeve 606 is fixedly installed on the inner wall of the swing gear 609. The swing sleeve 606 swings together with the swing gear 609. A connecting rod 301 is fixedly installed on the outer wall of the swing sleeve 606. The bottom of the connecting rod 301 is rotatably connected to the top of the rotating gear 605. Driven by the swing sleeve 606, the connecting rod 301 drives the rotating gear 605 and the spray assembly 7 at its bottom to swing at a certain angle, expanding the spray range.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
