Description

Technical Field

[0001] This utility model relates to the field of spinning flue gas emission technology, and in particular to a flue gas emission system for a winding workshop of porous fine denier polyamide 6. Background Technology

[0002] During the spinning process, various equipment is used in production, including auxiliary equipment such as guide rollers and network devices. In particular, the winding workshop for porous fine denier polyamide 6 produces a large amount of oily fumes and heat. These large amounts of oily fumes and heat have a direct impact on product quality and the workshop production environment. Therefore, there is a flue gas treatment device to collect the flue gas from all the equipment and then treat it centrally. After treatment, the flue gas and heat that do not affect the environment are directly discharged into the external environment.

[0003] The original flue gas was discharged separately through small filtration equipment, especially the large winding equipment. Moreover, separate pipes were set up for the flue gas emissions from different workshops to transport heat and flue gas to the highest point of the building. If necessary, the pipes could be extended a certain distance into the air before being discharged, in order to prevent smoke and heat from returning to the factory area and to prevent smoke from accumulating nearby.

[0004] However, because the pipes that draw gas upwards during exhaust are all individual exhaust outlets, they cannot be cleaned or repaired. Moreover, if the fan malfunctions, the entire production workshop will be unable to exhaust smoke, causing the smoke to accumulate and spread throughout the workshop.

[0005] Because these types of flue gas ducts need to intersect with other ducts, and there are many devices that need to exhaust smoke in order to avoid mutual interference, the duct design can only use small-diameter exhaust pipes with many bends and long pipes. This results in low suction power of the duct. On the other hand, if large exhaust pipes are used, they will take up a lot of space and cannot cover all the equipment through the large exhaust pipes.

[0006] In the production process of porous fine denier polyamide 6, the flue gas from this type of yarn is unstable and the amount of yarn spun is not fixed. This results in sometimes excessive local smoke in the workshop, sometimes a sudden increase in smoke throughout the entire workshop, and sometimes a sudden drop in smoke volume. A single exhaust pipe cannot meet this unstable smoke exhaust demand.

[0007] Based on this, this utility model designs a flue gas emission system for a winding workshop using porous fine denier polyamide 6 to solve the above-mentioned problems. Utility Model Content

[0008] The purpose of this invention is to provide a flue gas emission system for a winding workshop using porous fine denier polyamide 6. This system addresses the issue of numerous and complex equipment unable to cover large-diameter flue pipes. Instead, it connects all equipment to a larger-diameter flue pipe, which in turn connects to an exhaust pipe at a high point on the roof via an ascending flue. This facilitates the convenient transport of flue gas, utilizes multiple channels for transport, and increases the exhaust speed through multiple fans, effectively enhancing the overall suction power of the flue. Furthermore, this device allows for the independent opening or closing of the ascending flue, especially during flue cleaning, without requiring system shutdown. It can alter the flue gas direction without reducing suction power, thus ensuring safe production.

[0009] This utility model is implemented as follows: a flue gas emission system for a winding workshop of porous fine denier polyamide 6, comprising: Smoke collection pipe, smoke exhaust pipe, relay fan and rising flue; Both the smoke collection pipe and the smoke exhaust pipe are smoke exhaust pipes, and the smoke collection pipe is connected to the smoke exhaust port of all flue gas treatment equipment. The exhaust pipe is installed at high altitude and connected to the external environment; An oil drain pipe is also installed on the smoke collection pipe; Multiple rising flues are connected between the smoke collection pipe and the smoke exhaust pipe; Each of the rising flues is equipped with a smoke exhaust fan, and the smoke exhaust port of the smoke exhaust fan is connected to the smoke exhaust pipe; Multiple isolation valves are installed on the flue pipe, and an isolation valve is installed between two adjacent flue pipes; A relay fan is also installed between adjacent isolation valves, and the relay fan is a bidirectional fan; The relay fan is isolated and sealed from the rising flue through an isolation valve.

[0010] Furthermore, the exhaust port of the exhaust pipe opens downwards.

[0011] Furthermore, the relay fan is mounted on a reversing pipe, which is connected to the isolation valve via a flange.

[0012] Furthermore, an air valve is installed between each of the aforementioned rising flues and the flue gas collecting pipe.

[0013] Furthermore, a check valve is also installed on the oil drain pipe.

[0014] The beneficial effects of this utility model are: 1. This utility model adds two large-channel smoke collection pipes and smoke exhaust pipes, and also adds multiple rising flues to connect the smoke exhaust pipes and smoke collection pipes, forming a strong suction effect, effectively avoiding the situation where the small smoke pipe is connected when the smoke is discharged, resulting in insufficient suction. The smoke collection pipe is directly connected to the smoke treatment equipment, which can discharge and concentrate the smoke more quickly. 2. This device provides more exhaust channels through multiple rising flues, and can more quickly disperse and absorb the flue gas in the smoke collection pipe when different suction requirements are met, effectively improving the exhaust speed of the flue gas. 3. This device also includes a bidirectional booster fan and an isolation valve. When there is an abnormality in the rising flue of the smoke outlet, the individual pipe can be inspected and cleared without affecting the rest of the pipes and the overall smoke exhaust system. In addition, the booster fan can also make up for the missing suction power, thereby ensuring the smooth discharge of smoke in the production workshop. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0017] The attached diagram lists the components represented by each number as follows: 1-Smoke collection pipe, 11-Smoke exhaust pipe, 12-Oil exhaust pipe, 2-Intermediate fan, 21-Isolation valve, 22-Deflector pipe, 3-Rising flue, 31-Smoke exhaust fan. Detailed Implementation

[0018] Please see Figure 1 As shown, this utility model provides a flue gas emission system for a winding workshop of porous fine denier polyamide 6. In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] In a specific embodiment of the technical solution of this utility model: Includes smoke collection pipe 1, smoke exhaust pipe 11, relay fan 2 and rising flue 3; Both the smoke collection pipe 1 and the smoke exhaust pipe 11 are smoke exhaust pipes. The smoke collection pipe 1 is connected to the exhaust port of all flue gas treatment equipment. The exhaust pipe 11 is installed at a high altitude and connects to the external environment. The exhaust port of the exhaust pipe 11 opens downward to prevent rain and foreign objects from falling into the pipe. The smoke collection pipe 1 is also equipped with an oil drain pipe 12, and a check valve is installed on the oil drain pipe 12 to prevent external air from entering the smoke collection pipe 1 through the oil drain pipe 12. The oil in the smoke collection pipe 1 can be discharged downwards by itself through this invention. This valve can be a check valve for sewers, which can facilitate the discharge of oil by itself and prevent the air in the workshop from being entered into the smoke collection pipe 1. Multiple rising flues 3 are connected between the smoke collection pipe 1 and the smoke exhaust pipe 11; Each rising flue 3 is equipped with a smoke exhaust fan 31. The smoke exhaust port of the smoke exhaust fan 31 is connected to the smoke exhaust pipe 11. Each rising flue 3 is equipped with an air valve between it and the smoke collection pipe 1. The air valve can close the individual rising flue 3, thereby allowing for the inspection and unblocking of blocked or malfunctioning rising flues 3. Multiple isolation valves 21 are installed on the smoke collection pipe 1, and an isolation valve 21 is installed between two adjacent smoke risers 3; A relay fan 2 is also installed between adjacent isolation valves 21. The relay fan 2 is a bidirectional fan. The relay fan 2 is isolated and sealed from the rising flue 3 through the isolation valve 21.

[0020] The relay fan 2 is installed on a deflector pipe 22, which is connected to the isolation valve 21 via a flange. This allows the isolation valve 21 to be closed during normal operation of the exhaust duct, enabling maintenance and cleaning of the relay fan 2. When the relay fan 2 is working normally, the deflector pipe 22 can also compensate the entire exhaust duct system, ensuring efficient exhaust of the flue gas. In particular, when the local smoke is dense and the air pressure section has less smoke, the integrated smoke collection pipe 1 and exhaust pipe 11 can quickly disperse the smoke in the dense area and discharge it through multiple different rising smoke ducts 3, thus dispersing the smoke in the workshop more quickly.

[0021] It should be noted that this device is not simply one in use and one on standby; rather, all fans are working simultaneously, and each fan and each different rising flue duct 3 can be individually shut off and blocked for individual cleaning, making the entire smoke exhaust system smoother, with higher overall smoke exhaust efficiency, and a stronger ability to withstand abnormal risks.

[0022] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
