Background technique

For a long time, low bath ratio, high cloth speed, short dyeing process, labor saving and energy saving, and high level dyeing are all the performances that need to be improved urgently for air-liquid cloth dyeing machines. Whether these characteristics can be improved depends on the dyeing process. The temperature of the liquid is related to the heat exchanger. Therefore, the efficiency of the heat exchanger is the most important equipment for improvement and upgrading of the fabric dyeing machine manufacturers at present. However, the common types of circulating dye liquid heat exchangers are still stagnant. In the form of water cooling and steam heating, it is well known that a large amount of cooling water is used in water cooling, and the cooling water needs to be cooled or heated with high energy before it can be recycled. Therefore, in the overall dye liquor cooling process The energy or water resources consumed for cooling water treatment are extremely large and considerable. Therefore, if a high-efficiency circulating dyeing solution heat exchange device that does not consume the above-mentioned huge water resources or energy can be provided, the cost of dyeing operations can be greatly reduced. And improve the efficient use of resources.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Example 1

As shown in Figure 1, the heat exchanger 10 of the present invention is mainly installed between the inlet and outlet 31, 32 of the dye solution circulation pipe 30 of the dyeing machine 20;

As shown in Figures 2-6, the inside of the heat exchanger 10 is divided into a dye liquor circulation space 12 and a gas circulation space 13 by at least one compartment 11, and the dye liquor circulation space 12 is provided with a dye liquor inlet 121 and a dye liquor outlet. 122, and respectively connected to the branch pipes 321, 311 of the outlet 32 and the inlet 31 of the above-mentioned corresponding dye liquor circulation pipe 30; in addition, the above-mentioned gas circulation space 13 is provided with a gas inlet 131 and a gas outlet 132, and one end of the gas inlet 131 can be connected Cooling air source 40 such as air cooler or cold gas, and a steam source 50 is connected by the side; And gas outlet 132 is then connected with a condensing water cooler 60; or the ingress and egress of steam.

On the above-mentioned interlayer 11, a plurality of vacuum heat-conducting elements 14 are plugged and locked. The heat-conducting element 14 is generally a tubular body with an internal vacuum. The two ends of each stretch out respectively in the dye liquor circulation space 12 and the gas circulation space 13 on both sides of the interlayer 11; The heat transfer medium 141 in the heat conduction element 14 quickly flows to the end of the gas circulation space 13 to dissipate heat and condense after absorbing heat at one end of the dye liquid circulation space 12, and then circulates to the end of the dye liquid circulation space 12 to absorb heat, so that heat can be conducted due to vacuum The high heat conduction efficiency of the element 14 quickly and surely reduces the temperature of the circulating dye solution; on the contrary, when the circulating dye solution needs to be heated up, steam is input into the air circulation space 13, and the heat exchange direction is opposite, so that the temperature of the dye solution can be rapidly increased. And because the above-mentioned vacuum heat conduction element 14 can produce obvious and high-efficiency heat exchange under the extremely low temperature difference, the heat exchange efficiency will be improved, and the conditions for stable temperature control will be more stable, which will help to improve the level dyeing ability.

Example 2

As shown in Figure 3-8, in the heat exchanger according to the above characteristics, the arrangement of the inner compartment 11 and the vacuum heat conduction element 14 can be divided into: one is a flat compartment 11, which allows the overall heat exchange The interior of the device is divided into at least two evenly divided circulation spaces; the second is divided into inner and outer concentric circulation spaces by a concentric wall partition 110, and each vacuum heat conduction element 14 is also inserted on the partition, so that The two ends protrude into the two circulation spaces respectively.

In summary, the present invention does provide a high-efficiency heat exchanger device, which not only improves the heat exchange efficiency, but also uses cold air and steam with the lowest pollution and good heat transfer rate for cooling and heating, which is sufficient for cooling and heating The speed is accelerated, and it has the characteristics of energy saving, short dyeing process, high efficiency, low pollution and high level dyeing.
