Dye vat water circulation system

Abstract

The invention discloses a dye vat water circulation system, and belongs to the field of textile printing and dyeing equipment. The dye vat water circulation system comprises a dye vat (1) and a water injection pump (6) for injecting water into the dye vat (1), and a heat exchanger is arranged in the dye vat (1). The dye vat water circulation system is characterized in that a recycled water tank (9) is arranged, a heat exchange water outlet of the heat exchanger is connected into the recycled water tank (9) through a pipeline, a water inlet of the water injection pump (6) is connected to the bottom of the recycled water tank (9) through a pipeline, a water outlet of the water injection pump (6) is connected to the top of the dye vat (1) through a dye vat water filling pipe (2), and a water hammer eliminating branch is arranged between the water injection pump (6) and the recycled water tank (9). According to the dye vat water circulation system, secondary application of heat exchange water of the heat exchanger is realized by the aid of the recycled water tank, waste of water resources is avoided, and water hammer in the pipelines is eliminated when the water injection pump stops working.

Description

technical field [0001] A water circulation system for a dye vat belongs to the field of textile printing and dyeing equipment. Background technique [0002] The printing and dyeing process is a link of high energy consumption, high water consumption and high pollution in the textile industry. Generally, a heat exchanger is installed in the dyeing vat to heat the water in the dyeing vat, so that the water temperature in the dyeing vat reaches the appropriate temperature of the dye. In the prior art, after finishing printing and dyeing, the waste water in the dyeing vat and the heat exchange water for the dye in the dyeing vat are all drained away, because the heat exchange cycle in the dyeing vat does not interact with the dyeing vat. The dyes in the heat exchanger are in contact with each other, so the exchange water discharged from the heat exchanger is not polluted water, and the waste of water resources is greatly increased after being directly discharged. In the printin...

Problems solved by technology

In the prior art, after finishing printing and dyeing, the waste water in the dyeing vat and the heat exchange water for the dye in the dyeing vat are all drained away, because the heat exchange cycle in the dyeing vat does not interact with the dyeing vat. The dyes inside are in contact with each other, so the exchange water discharged from the heat exchanger is not polluted water, and the waste of water resources is greatly increased after direct discharge

In the printing and dyeing process, due to the frequent injection of water in the dyeing vat, the corresponding injection pump is in a state of frequent start and stop, which affects the service life of the injection pump, and also has the following problems: whenever the injection pump stops working, the water in the tube It will form a more serious water hammer phenomenon, which will form a greater impact on the equipment in the pipeline, causing severe vibration in the pipeline and will greatly shorten the service life of the equipment in the pipeline. Although there are water hammer elimination in the prior art Equipment such as devices, but the effect is poor and the cost is high
