[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a chimney for treating acidic waste gas from unsaturated resin. Background Technology

[0002] In the chemical production field, the production process of unsaturated resins generates a large amount of waste gas containing acidic substances. This waste gas is characterized by strong corrosiveness and high temperature. Chimneys for treating acidic waste gas from unsaturated resins serve as key equipment for waste gas emission, playing a crucial role in safely and efficiently discharging the treated acidic waste gas into the atmosphere.

[0003] Traditional chimneys struggle to simultaneously achieve both high strength and good thermal insulation, making them prone to structural deformation and even damage under long-term stress from internal exhaust gas pressure, external wind force, and thermal expansion and contraction, posing safety hazards. Furthermore, they lack intelligent mechanisms for adjusting exhaust gas flow and velocity, making it difficult to optimize exhaust emissions in real time according to different operating conditions and adapt to diverse production needs, thus affecting exhaust gas treatment effectiveness. Therefore, a chimney using unsaturated resin acidic exhaust gas treatment is proposed. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a chimney for treating acidic waste gas from unsaturated resin, aiming to improve the existing technology's lack of a mechanism for intelligently adjusting waste gas flow rate and velocity, making it difficult to optimize waste gas emission status in real time according to different working conditions and adapt to diverse production needs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chimney for treating acidic waste gas from unsaturated resin, comprising a chimney body, an exhaust pipe fixedly connected to the outer wall of the chimney body, an outer shell fixedly connected to the outer wall of the exhaust pipe, an adjustment component provided inside the outer shell, and a drive component provided at the bottom of the outer shell;

[0006] The adjustment assembly includes two guide rods, which are fixedly connected inside the housing. Two sliders are slidably connected to the outer wall of the guide rods, and a baffle is fixedly connected between the outer walls of the two sliders. A spring is sleeved on the outer wall of the guide rod.

[0011] As a further description of the above technical solution:

[0012] The height of the baffle is greater than the inner diameter of the exhaust pipe, but less than half the height of the guide rod.

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected to the inner wall of the outer casing, and the other end of the spring is fixedly connected to the top of the slider.

[0029] 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.

[0030] Reference Figures 1-3 The present invention provides an embodiment of a chimney for treating acidic waste gas from unsaturated resin, comprising a chimney body 1, which serves as the main structure of the entire chimney and is the main channel for the emission of acidic waste gas from unsaturated resin. An exhaust pipe 2 is fixedly connected to the outer wall of the chimney body 1, which is used to discharge the acidic waste gas from unsaturated resin into the interior of the chimney body 1. An outer shell 3 is fixedly connected to the outer wall of the exhaust pipe 2, providing installation space for the adjustment component and drive component installed inside. An adjustment component is installed inside the outer shell 3, which adjusts the flow rate or direction of the waste gas in the exhaust pipe 2 according to actual needs to adapt to the waste gas treatment requirements under different working conditions. A drive component is installed at the bottom of the outer shell 3, which provides a power source for the adjustment component, enabling it to achieve automatic adjustment.

[0031] Reference Figure 2 The adjustment assembly includes two guide rods 4, which are fixedly connected inside the housing 3. The guide rods 4 provide a stable track for the subsequent sliding of the slider 5, ensuring that the slider 5 will not deviate or shake during movement. Two sliders 5 are slidably connected to the outer wall of the guide rods 4. The sliders 5 can slide along the axial direction of the guide rods 4, and drive the baffle 6 connected to them to move through their sliding, thereby realizing the adjustment of the internal space of the exhaust pipe 2. A baffle 6 is fixedly connected between the outer walls of the two sliders 5. The baffle 6 is the core component of the adjustment assembly. By changing its position, the cross-section of the exhaust gas flow in the exhaust pipe 2 can be adjusted, thereby controlling the flow rate and velocity of the exhaust gas. A spring 7 is sleeved on the outer wall of the guide rods 4. The spring 7 can provide a restoring force after the sliders 5 and the baffle 6 move, so that the baffle 6 can automatically return to the initial position when no adjustment is needed.

[0032] Reference Figure 2 The drive assembly includes a housing 8, which is fixedly connected to the bottom of the outer shell 3. The housing 8 serves as the main structure of the drive assembly, providing a space for the paraffin wax inside. The housing 8 is filled with paraffin wax, which has the property of changing its physical state with temperature. Utilizing this property, when the temperature of the exhaust gas changes, the paraffin wax will melt or solidify accordingly, thereby generating a volume change and providing a power source for the drive assembly. A connecting rod 9 is fixedly connected to the top of the housing 8, and the top of the connecting rod 9 is fixedly connected to the bottom of the baffle 6. The connecting rod 9 plays the role of connecting and transmitting the force generated by the volume change of the paraffin wax inside the housing 8 to the baffle 6, so that the baffle 6 can move under the action of the drive assembly, thereby regulating the exhaust gas in the exhaust pipe 2.

[0033] Reference Figure 3 The chimney body 1 is divided into a support layer 10, a heat insulation layer 11, and an anti-corrosion layer 12 from the outside to the inside. The support layer 10 is located on the outermost layer and mainly bears the structural strength of the entire chimney body 1, ensuring that the chimney can maintain a stable shape under various environmental conditions and operating conditions. The heat insulation layer 11 is located in the middle position and its function is to effectively block the heat of the high-temperature exhaust gas inside the chimney from being transferred to the outside, reducing heat loss. The anti-corrosion layer 12 is located on the innermost layer and is in direct contact with the acidic exhaust gas of the unsaturated resin, which can prevent the acidic exhaust gas from corroding the inner wall of the chimney and extend the service life of the chimney.

[0034] Reference Figure 2 The height of baffle 6 is greater than the inner diameter of exhaust pipe 2 and less than half the height of guide rod 4. The height of baffle 6 is greater than the inner diameter of exhaust pipe 2, which ensures that baffle 6 can completely cover the internal space of exhaust pipe 2 during movement, thereby achieving effective control of exhaust gas flow and avoiding exhaust gas leakage or inability to fully adjust. The height of baffle 6 is less than half the height of guide rod 4, which is to ensure that baffle 6 has enough room to move on guide rod 4, so that it can be flexibly adjusted under the action of drive component.

[0035] Reference Figure 2 One end of the spring 7 is fixedly connected to the inner wall of the outer casing 3, and the other end of the spring 7 is fixedly connected to the top of the slider 5. This allows the spring 7 to be compressed or stretched when the slider 5 slides on the guide rod 4, causing the baffle 6 to move, thereby storing elastic potential energy. When the driving force of the drive component disappears, the elastic potential energy stored in the spring 7 is released, pushing the slider 5 and the baffle 6 back to their initial positions, thus realizing the automatic reset function of the adjustment component.

[0036] Reference Figure 3The support layer 10 is made of carbon steel, which has high strength and good toughness, providing solid structural support for the chimney body 1. During the treatment of acidic waste gas from unsaturated resin, the chimney needs to withstand the pressure generated by the internal waste gas, external wind force, and its own gravity load.

[0037] Reference Figure 3 The insulation layer 11 is made of rock wool, which has excellent heat insulation properties and can effectively prevent the heat from the high-temperature exhaust gas inside the chimney from being transferred to the outside. In the case of treating acidic exhaust gas from unsaturated resin, the exhaust gas usually carries a high temperature. If a large amount of heat is lost, it will not only waste energy but also raise the temperature of the outer wall of the chimney.

[0038] Reference Figure 3 The anti-corrosion layer 12 is made of fiberglass and ceramic fiber. Fiberglass has good corrosion resistance and can effectively resist the chemical erosion of unsaturated resin acidic exhaust gas, preventing acidic substances from corroding and damaging the inner wall of the chimney. Ceramic fiber has high temperature resistance and wear resistance, and can maintain stable physical and chemical properties in high temperature exhaust gas environment, further enhancing the protective ability of the anti-corrosion layer 12.

[0039] Working principle: When exhaust gas is transmitted to exhaust pipe 2, the drive assembly starts to work. If the exhaust gas temperature rises, the paraffin wax filled in housing 8 melts and expands in volume, pushing baffle 6 upward through connecting rod 9. Guided by two guide rods 4, baffle 6 slides along slider 5, compressing spring 7. At this time, baffle 6 changes position, adjusting the exhaust gas flow cross-section in exhaust pipe 2, controlling the flow rate and velocity of exhaust gas, and thus regulating exhaust gas emissions. When the exhaust gas temperature decreases, the solidified paraffin wax shrinks in volume, spring 7 releases elastic potential energy, pushing slider 5 and baffle 6 downward to return to their initial positions for the next adjustment.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
