Description

Technical Field

[0001] The utility model belongs to the technical field related to spandex production, and particularly relates to a device for recycling spandex waste liquid. Background Art

[0002] Dry spinning is the most commonly used method in spandex production, and about 80% of spandex is spun by this method. Due to the polymerization characteristics of dry spinning and the shedding of tank and pipeline retentate, it is necessary to add a filter before transporting to spinning. During the filter replacement process, a certain amount of waste stock solution needs to be generated. The periodic replacement of the reactor and the replacement of the spinning component will generate waste stock solution, but it still has the following disadvantages in actual use:

[0003] One way to deal with the waste of spandex stock solution is to entrust a company with hazardous waste treatment qualifications to handle it. Another way is to soak it in water for solidification and treat it as hazardous waste after solidification. The solidification cycle is long, and DMAC gas will volatilize during the process, polluting the air and generating a large amount of process wastewater. This treatment method will not only bring environmental pressure, but also cause material waste;

[0004] Whether the waste liquid of spandex raw liquid is processed or recycled, it is necessary to determine the state of the spandex raw material. When determining the state of the raw material, direct observation by staff often results in large errors and inaccurate state determination. Therefore, sampling is required. When sampling is performed directly, the processing equipment needs to be opened and some of the spandex waste liquid needs to be taken out. The removal operation is relatively cumbersome, and the operator is exposed to more DMAC gas, which is prone to safety hazards. Utility Model Content
