Embodiment

[0014] Example: such as figure 1 As shown, a heat exchange circulation system of a dyeing machine includes a dyeing machine 1, a heat exchanger 2, an insulating water tank 3 and a cooling pool 4. The dyeing machine 1 is provided with a cooling pipe for cooling down and a heating pipe for heating up, and the dyeing machine 1 is connected with the heat exchanger 2 through a conduit 11 . The heat exchanger 2 is connected with a steam pipeline 21, and the steam pipeline 21 is connected with the inlet of the heating pipe of the dyeing machine 2 through a diverter valve 23, and the steam in the steam pipeline 21 heats the heat exchanger 2 and the dyeing machine 1 simultaneously. The heat exchanger 2 is connected with the thermal insulation water tank 3 through the connecting pipe 22, and the steam is discharged into the thermal insulation water tank 3 after heating the heat exchanger 2 for recovery.

Abstract

The invention relates to the technical field of printing and dyeing equipment, in particular to a heat exchange circulating system for a dyeing machine. The heat exchange circulating system for the dyeing machine comprises the dyeing machine, a heat exchanger, a heat preservation water tank and a cooling pool; the heat exchanger is connected with a steam pipeline, the dyeing machine is connected with the heat exchanger through a guide pipe, a cooling pipe and a heating pipe is arranged in the dyeing machine, a water inlet of the cooling pipe is connected with a cold water pipe connected with the cooling pool, a water outlet of the cooling pipe is connected with a three-way pipe, and the three-way pipe is connected with the cooling pool and the heat preservation water tank; the cooling pool is connected with the heat exchanger through a cooling branch pipe and a cooling return pipe, the heat exchanger is connected with the heat preservation water tank through a connecting pipe, the heat preservation water tank is connected with the heating pipe through a hot water pipe, and an outlet of the heating pipe is connected with the three-way pipe. The heat exchange circulating system for the dyeing machine is high in heat energy recovery utilization rate and capable of reducing heat energy waste and lowering the production cost.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing equipment, in particular to a heat exchange circulation system of a dyeing machine. Background technique [0002] The high-temperature and high-pressure dyeing machine can be used for pretreatment, alkali reduction, dyeing and washing of various chemical fiber fabrics. During the production and heating process, a large amount of steam is required to heat the dye liquor in the dyeing vat from normal temperature to high temperature through a heat exchanger. , a considerable amount of high-temperature water with a relatively high temperature is produced in the process. At the same time, after the high-temperature and high-pressure dyeing treatment, the cooling water is used to cool the dye vat for a period of time after heat preservation, and then the dyeing vat is cooled and pressure-treated. During this process, a large amount of steam and high-temperature cooling water will be generate...
