Overflow dyeing system of gas flow atomization dyeing machine and water using method thereof

Abstract

The invention relates to an overflow dyeing system of a gas flow atomization dyeing machine and a water using method thereof. The overflow dyeing system is characterized in that a filter mesh I is arranged between a main pump and a heat exchanger in a matching manner, the output pipeline of the heat exchanger is connected with an overflow spray nozzle through an overflow spray nozzle connecting pipe valve, and the overflow spray nozzle is positioned above a gas flow spray nozzle; and an additional pump is connected and arranged on the pipeline of the main pump in parallel, and a connecting valve I and a connecting valve II are arranged and connected on two end pipelines connected with the additional pump. By adopting the overflow dyeing system, the electricity consumption can be effectively saved, and the limitations in dyeing by a gas flow dyeing machine can be solved. The overflow dyeing system simultaneously has the gas flow and overflow dyeing systems, thereby avoiding wrinkling of terylene and other gray cloth when passing through high-temperature gas flow at the temperature of 130 DEG C for dyeing, further reducing the electricity consumption consumed by a fan when drying by the high-temperature gas flow, saving energy and expanding the range of applications of the dyeing machine.

Description

technical field [0001] The invention relates to an overflow dyeing system of an airflow atomization dyeing machine and a water use method thereof. Background technique [0002] In the field of existing air-flow dyeing machines, gray cloth is driven by air flow and cloth guide wheel during pretreatment and dyeing, and the ratio of water to cloth is quite small, generally cotton gray cloth is 1:3-4, polyester gray cloth is 1:2-4 , so as to save water, save dyeing materials, and reduce waste water discharge. It is one of the environmentally friendly dyeing machines for gray cloth pretreatment and dyeing. However, the airflow dyeing machine uses the airflow of the fan as the main power to drive the gray cloth, and the power of the fan is large and the power consumption is large. Especially when dyeing at a high temperature of 130°C, the actual power consumption is more than twice that at room temperature and pressure below 100°C. In addition, when dyeing polyester or polyester-...

AI Technical Summary

Problems solved by technology

However, the airflow dyeing machine uses the airflow of the fan as the main power to drive the gray cloth, and the power of the fan is large and the power consumption is large.

Especially when dyeing at a high temperature of 130°C, the actual power consumption is more than twice that at room temperature and pressure below 100°C. In addition, when dyeing polyester or polyester-cotton gray fabrics at a high temperature of 130°C, the dyeing result will produce fish scales and regular wrinkles. It is difficult to solve this problem even through post-finishing high-temperature tentering

Therefore, high temperature and high pressure dyeing at around 130°C by the airflow dyeing machine has a certain impact on the quality of polyester or polyester cotton gray fabrics, and consumes a lot of energy, which has shortcomings.
