Description
Technical Field
The utility model relates to a steam thermodynamic system adopted by a printing and dyeing mill, in particular to a steam thermodynamic cycle energy-saving system.
Background
At present, in a traditional steam thermodynamic system (as shown in figure 2) adopted by a traditional printing and dyeing mill, high-pressure steam enters a steam distribution pipe through a manual valve and then enters a drying cylinder, the steam is subjected to heat release condensation in the drying cylinder, condensed water and a small amount of steam enter a condensed water collecting pipe through a drain valve, then flash steam is directly discharged, and the condensed water is recycled. In the traditional steam thermodynamic system, because the input of steam is adjusted through a manual valve, the valve cannot be timely adjusted in the process of adjusting the steam quantity, so that part of steam is wasted; because the drying cylinder is not smooth in drainage, the drain valve can generate air resistance, and the capillary tube is usually adopted to break the steam lock and exhaust steam, thereby causing the waste of steam. Due to poor drainage, the water film accumulated in the drying cylinder is thick, the thermal resistance of the drying cylinder is high, and the heat exchange efficiency inside and outside the drying cylinder is limited. The circulation of steam and condensed water in the drying cylinder is not smooth, so that the temperature difference between the front end and the rear end of the drying cylinder is large, and the quality of a product is influenced. The condensed water and the steam are directly discharged, so that the steam is wasted, and the heat of the condensed water is not fully utilized, thereby causing heat waste. Therefore, the traditional steam thermodynamic system adopted by the current printing and dyeing mill has the problems of high steam waste rate, limited heat exchange efficiency inside and outside the drying cylinder, great influence on product quality and waste due to insufficient utilization of heat.
