Problems solved by technology

The composition of the oil mist in the nylon filament production workshop is relatively complex, the most important being saturated fatty acids. Although the production equipment itself has a local exhaust device, it still cannot completely prevent the oil mist from spreading into the air.
In short, the polluted air will cause damage to the health of the workers in the workshop on the one hand, and on the other hand, such as natural emissions, will have a greater impact on the health of surrounding residents and the natural environment

Abstract

Belonging to the field of environmental protection, the invention particularly discloses a treatment process suitable for spinning plant waste gas. According to the treatment process suitable for spinning plant waste gas, mainly spinning plant waste gas is introduced into a water spraying tower and flows from the bottom up the water spraying tower, and a water spraying device at the upper part ofthe water spraying tower sprays atomized water vapor to flush the waste gas from top to bottom. The treatment process suitable for spinning plant waste gas can effectively remove polyamide oligomer, oil mist and smoke dust from spinning long waste, and has the characteristics of high comprehensive utilization rate of resources, low energy consumption, convenient operation, stable running, and lowcost.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a treatment process suitable for waste gas from spinning mills. Background technique [0002] Spinning mills produce a lot of harmful gases during the production process. Taking the production of nylon filament as an example, the main pollutants in the air are polyamide oligomers and emulsified oil mist. During the production process, the high temperature generated by screw extrusion will lead to the precipitation and volatilization of polyamide oligomers, thereby polluting the air in the workshop; the spinning production process requires that the tow must be heated and drawn, and the heated and drawn tow will cause emulsification The oil evaporates. As a result, the air in the production workshop contains a faint pungent odor and forms a gray oil mist, accompanied by a small amount of smoke. Through further analysis, testing and data statistics, under norma...
