A waste silk processing system for chemical fiber factories and its working process

Abstract

The invention discloses a waste silk processing system for a chemical fiber factory and its working flow, relates to the textile field, and aims to solve the problem that carbon disulfide cannot be recovered and reused in the process of processing waste silk and the potential safety hazards occur. The system includes a waste silk tank, an exhaust pipe and a spraying device. The waste silk tank is connected to the waste water pipe. The exhaust pipe is installed inside the waste silk tank and the exhaust pipe extends out of the waste silk tank. The spraying device Installed above the waste silk trough, the waste silk trough is respectively connected with the supplementary water pump and the waste water pump, and the waste silk trough is connected with the sky net pipeline through the waste water pump, and the surface of the waste silk trough is also provided with a fishing port. This product can remove the carbon disulfide attached to the surface and inside of the waste silk by spraying and soaking the waste silk with alkaline water, which greatly reduces the concentration of carbon disulfide gas before the waste silk enters the dryer, and can reuse carbon disulfide, avoiding The emission of carbon disulfide reduces the potential safety hazards in the waste silk treatment process and has positive social benefits.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a waste silk processing system for chemical fiber factories. Background technique [0002] Chemical fiber is the abbreviation of chemical fiber. It is a fiber with textile properties obtained by using natural polymer compounds or artificially synthesized polymer compounds as raw materials through the preparation of spinning stock solution, spinning and post-treatment processes. The length and thickness of the fibers , whiteness, gloss and other properties can be adjusted in the production process, and are widely used in the manufacture of clothing fabrics, filter cloths, conveyor belts, hoses, ropes, fishing nets, electrical insulating threads, medical sutures, tire cords and parachutes, etc. [0003] Chemical fiber factories inevitably produce a large amount of waste silk due to various reasons. The development and utilization of waste silk is a work of ecological and economic significan...

AI Technical Summary

Problems solved by technology

[0004] During the waste silk recycling process, because the waste silk contains a large amount of carbon disulfide and other substances used as auxiliary raw materials, the waste silk produced cannot be processed by the normal product process procedures. The existing waste silk treatment methods are waste silk collection, throwing Drying and drying are simply dehydration of the waste silk, which leads to the inability to recycle the carbon disulfide in the waste silk, which also indirectly leads to some safety problems due to the high concentration of carbon disulfide in the process of processing waste silk.

For example, when the waste silk is dried, the possibility of a flash explosion event is greatly increased due to the high concentration of carbon disulfide. At the same time, due to problems such as drying, the carbon disulfide in the waste silk is directly discharged into the environment, causing environmental pollution.

This has a great impact on the current energy-saving and emission-reduction projects in the chemical fiber industry
