Application of thermal oil furnace in printing and dyeing industry

In the early days of the printing and dyeing industry, stentering machines were heated using organic heat transfer furnaces instead of electric heating, using coal instead of electricity, significantly reducing energy costs. Converting steam to organic heat transfer furnaces can significantly reduce energy consumption and production costs. Organic heat transfer furnaces, with their high pressure, high temperature, indirect heating, and safe and reliable heating characteristics, meet the needs of many industrial production processes. Using steam to heat the dyeing solution requires 10-12 tons of steam, while using thermal oil only consumes 1,000-1,200 kilograms of coal. Using thermal oil furnaces saves 30-50% of energy, significantly reducing production costs.

The dyeing liquid heating device utilizes an organic heat transfer medium (thermal oil). The inlet and outlet ports on the cylindrical shell are connected to the oil inlet and outlet of the thermal oil boiler via oil pipes, respectively. This creates a closed oil circulation circuit between the thermal oil and the cylindrical shell. During the heating process, no energy is lost except for heat conduction within the device itself. Furthermore, the thermal oil is recyclable and has a near 100% utilization rate. The use of a thermal oil boiler to heat the dyeing liquid within the heat exchange tubes ensures a relatively smooth heating process, thereby extending the life of the equipment.

The dyeing machine thermal oil boiler primarily utilizes a dye channel connected from the dye tank to the inlet of the circulating pump. The filter is mounted on the outlet of the circulating pump, the cloth delivery rack is mounted on the dye tank, the dye bucket and liquid level gauge are connected to the dye channel, the heater and condenser are mounted on the dye tank, and a regulating valve is installed between the filter, heater, and condenser. The pipe is flange-fastened to the dye tank and is equipped with the relevant valves, platinum resistance thermometer, pressure gauge, etc. Recyclable and without loss, the utilization rate is near 100%.
