Green and environment-friendly sewage treatment device and method for superfine fiber production

Abstract

The invention discloses a green and environment-friendly sewage treatment device and method for superfine fiber production, the device comprises a sewage treatment device body, and the sewage treatment device body comprises a movable water receiving primary treatment device and a fixed sewage treatment device; a pipeline I is arranged between the movable water-receiving primary treatment device and the fixed sewage treatment device, supporting legs are arranged at the bottom of the movable water-receiving primary treatment device, universal wheels are arranged at the bottoms of the supporting legs, fixed supporting legs are arranged at the bottom of the fixed sewage treatment device, and a pipeline II is arranged at the bottom of the fixed sewage treatment device. A handle is arranged on the side wall of the movable water receiving primary treatment device, a first water inlet pipe is arranged on the upper portion of the movable water receiving primary treatment device, a first water inlet tank is embedded into the first water inlet pipe, and the interior of the movable water receiving primary treatment device is of a cavity structure. The sewage treatment device has the beneficial effects that the structure is compact, the working intensity of workers is reduced, the sewage treatment effect for superfine fiber production is improved, and the discharge of small particles in the sewage for superfine fiber production is reduced.

Description

technical field [0001] The invention relates to the technical field of ultra-fine fiber production, in particular to a green and environment-friendly sewage treatment device and method for ultra-fine fiber production. Background technique [0002] Synthetic fibers made of polyacrylonitrile or acrylonitrile copolymer with an acrylonitrile content greater than 85% (mass percent). The commonly used second monomer is a non-ionic monomer, such as methyl acrylate, methyl methacrylate, etc., and the third monomer is an ionic monomer, such as sodium propylene sulfonate and the like. [0003] As early as more than 100 years ago, people have made polyacrylonitrile, but because there is no suitable solvent, it cannot be made into fiber. In 1942, German H. Rhein and American G.H. Latham discovered dimethylformamide solvent almost at the same time, and successfully obtained polyacrylonitrile fiber. In 1950, the American DuPont Company first carried out industrial production. Later, a ...

Problems solved by technology

[0004] Yet, although existing production method can produce superfine fiber, still there are many defects: 1, mainly adopt fixed sewage treatment device in the existing equipment For the treatment of wastewater after the production of microfiber, due to the fixed height of the sewage treatment device, or the problem that the existing sewage treatment device needs to realize the sewage treatment process in stages, the device cannot conveniently treat the sewage. Therefore, it is inconvenient to treat the waste water in different stages, and at the same time, it is not convenient to connect the waste water outlets of different production devices.

2. In the existing wastewater treatment device, it is impossible to produce preheating effect on the wastewater, which makes it easy to cause insufficient reaction in the subsequent sewage treatment process.

3. In the production process of the existing microfiber, due to the presence of cut raw materials or curly waste in the process, it is difficult to remove the curly waste or cut waste in the sewage treatment process, thus easily causing curly waste Or the cut waste is directly discharged

4. Among the existing sewage treatment devices, there are mainly sewage treatment devices for each process, which has the problem that the treatment efficiency is not high, and it is easy to increase the cost of sewage treatment for enterprises
