The printing and dyeing line transforms steam into organic heat carrier to save energy and greatly reduce production cost. The organic heat carrier furnace has many high-temperature, indirect heating, safe and reliable heating characteristics, which can meet many industrial production requirements. Recently, such as Shaoxing Yongfeng, Xiangshan Zhejiang Giant Eagle Group and Ningbo Juying Katie Garment Co., Ltd., after technical research, boldly transformed the dyeing machine steam heating into organic heat carrier heating and achieved gratifying results.

    The system overcomes two problems of steam heating. One is that the steam entering the cylindrical casing is directly discharged from the outlet of the simple casing after heating the heat exchange tube, and can only be used once, not only heat. The utilization rate is low (usually only about 30%) and it is a serious waste of water resources. The second is waste of energy and high cost of use. For example, dyeing one ton of polyester cotton and heating the dyeing liquid with steam requires 10~ 12 tons of steam, while using heat-conducting oil to heat the dyeing liquid, only consume 1000-1200 kg of coal, and use heat-conducting oil to heat energy to save 30~50%, greatly reducing production costs.
Organic heat carrier heating boiler for printing and dyeing industry
    The dyeing liquid utilizes an organic heat carrier {heat-conducting oil} heating device in which the inlet and the outlet on the cylindrical casing are respectively communicated with the oil-out n and the oil inlet of the heat-conducting oil boiler through the oil pipe, thereby making the heat-conducting oil and the cylindrical casing Form a closed circulating oil path. In the heating process, in addition to the heat conduction of the equipment itself, there is no other loss of electricity, and the heat transfer oil can be recycled without loss. The utilization rate is close to 100%, and the heat transfer oil is used for replacement. The medium dyeing liquid in the heat pipe is heated, so that the heating process of the dyeing liquid in the heat exchange tube is relatively stable, thereby prolonging the life of the equipment.

    The dyeing machine heat conduction oil heating device is mainly connected to the circulation pump inlet from the dyeing tank by the dyeing liquid passage, the filter is installed at the outlet of the circulation pump, the cloth distribution frame is installed on the dyeing tank, and the paint barrel and the liquid level meter are respectively connected to the dyeing liquid. On the channel, the heater and condenser are installed on the dyeing tank, the regulating valve is installed in the middle of the filter, heating and condenser, the connecting tube is fixed on the dyeing tank by flange, and the relevant valve, platinum thermal resistance, pressure gauge, etc. are installed. .
