Description

Technical Field

[0001] This utility model relates to the field of stenter technology, specifically to a multi-stage circulation treatment mechanism for stenter exhaust gas. Background Technology

[0002] Stenter machines generate a large amount of oily fumes during operation. These fumes contain pollutants such as lubricants, plasticizers, dyes, and dye auxiliaries (including waxes, solvents, emulsifiers, and polymer monomers). Their chemical composition is highly complex, including at least alkanes, esters, alcohols, ketones, aldehydes, heterocyclic compounds, and polycyclic aromatic hydrocarbons. In existing technologies, stenter exhaust gas treatment typically involves spray cooling, which not only lowers the exhaust gas temperature but also removes some oil. However, relying solely on spray cooling for stenter exhaust gas treatment is ineffective, leaving some oil residue in the exhaust gas.

[0003] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a multi-stage circulation treatment mechanism for waste gas from a stenter to solve the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-stage circulation treatment mechanism for waste gas from a stenter includes a treatment box, with an outlet pipe and an inlet pipe respectively provided on both sides of the treatment box. The treatment box is provided with several main filter screens, and a pair of parallel connecting slots are opened above each main filter screen. The pair of connecting slots are respectively arranged on both sides of the main filter screen, and a circulation pipe is provided on each pair of connecting slots. The circulation pipe is fixed to the top surface of the treatment box.

[0008] Preferably, a circulation fan and a secondary filter are respectively provided in the pair of connecting slots, the circulation fan in the pair of connecting slots is located on the side away from the air intake pipe, and the secondary filter in the pair of connecting slots is located on the side close to the air intake pipe.

[0009] Preferably, a sealing ring is provided on the top surface of the processing box, and the sealing ring is located on the outside of the connecting slot.

[0010] Preferably, a connecting plate is provided at the lower end of the circulation pipe. The area of ​​the connecting plate is larger than that of the sealing ring. The connecting plate presses on the sealing ring, and the connecting plate is connected to the top surface of the processing box by bolts.

[0011] Preferably, an observation window is provided on the side of the circulation pipe, and the observation window is located on the side close to the secondary filter screen.

[0012] (III) Beneficial Effects

[0013] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: The multi-stage circulation treatment mechanism for waste gas from a stenter in this utility model has multiple sets of circulation boxes on the treatment box. When the waste gas flows in the treatment box, it first passes through the main filter screen, and then enters the circulation box under the action of the circulation fan, where it is filtered by the secondary filter screen, and then passes through the main filter screen for a second time. The cooperation between each main filter screen and each circulation box enables the waste gas to undergo three filtrations, which greatly increases the filtration effect.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] This utility model embodiment provides a multi-stage circulation treatment mechanism for waste gas from a stenter, such as... Figure 1-3 As shown, the device includes a processing box 1. The processing box 1 has an air outlet pipe 2 and an air inlet pipe 3 on its two sides. The processing box 1 has several main filter screens 4. Each main filter screen 4 has a pair of parallel connecting slots 5 on its upper side. The pair of connecting slots 5 are respectively set on both sides of the main filter screen 4. Each pair of connecting slots 5 has a circulation pipe 6, which is fixed to the top surface of the processing box 1.

[0020] Reference Appendix Figure 2-3 Each pair of connecting slots 5 contains a circulating fan 7 and a secondary filter 8. The circulating fan 7 in the pair of connecting slots 5 is located on the side away from the intake pipe 3, and the secondary filter 8 in the pair of connecting slots 5 is located on the side closer to the intake pipe 3. (See attached...) Figure 2Taking a specific perspective as an example, the exhaust gas, after being sprayed, enters the treatment chamber 1 through the right-side inlet pipe 3. It first passes through the main filter 4, then, under the action of the circulation fan 7, enters the circulation pipe 6, passes through the secondary filter 8, and re-enters the treatment chamber 1, where it is filtered a second time by the main filter 4. The circulation process of the exhaust gas within the treatment chamber can be controlled by adjusting the power of the circulation fan 7 and the rate at which the exhaust gas enters the treatment chamber 1.

[0021] Reference Appendix Figure 2-3 A sealing ring 9 is provided on the top surface of the treatment box 1, and the sealing ring 9 is located outside the connecting slot 5. A connecting plate 10 is provided at the lower end of the circulation pipe 6. The area of ​​the connecting plate 10 is larger than that of the sealing ring 9. The connecting plate 10 presses on the sealing ring 9 and is connected to the top surface of the treatment box 1 by bolts. Under the action of the bolts, the connecting plate 10 tightly presses the sealing ring 9, ensuring the airtightness. After the circulation pipe 6 is disassembled, the circulation fan 7 and the secondary filter screen 8 can be easily cleaned and replaced.

[0022] Reference Appendix Figure 1-3 An observation window 11 is provided on the side of the circulation pipe 6. The observation window 11 is located on the side close to the secondary filter screen 8, so as to facilitate observation of the usage status of the secondary filter screen 8 and timely replacement.

[0023] This utility model discloses a multi-stage circulation treatment mechanism for waste gas from a stenter. Multiple circulation boxes are set on the treatment box. When the waste gas flows in the treatment box, it first passes through the main filter screen, and then enters the circulation box under the action of the circulation fan. It is then filtered by the secondary filter screen, and then passes through the main filter screen a second time. The cooperation of each main filter screen and each circulation box enables the waste gas to undergo three filtrations, which greatly increases the filtration effect.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
