摘要:

电费是无纺布纤维定型过程中除原料外的第二大生产成本,如何使其降低成为提高产品盈利的关键措施之一。基于国家为鼓励电力的削峰填谷实施的“峰谷平电价”用电策略,提出一种基于储能技术的纤维定型用单罐式储能换热系统,并对其关键部分的设计方法进行了阐述。结合河北某纺织企业的应用案例,通过理论计算,若采用储能换热系统与传统纤维加热装置相比可节省用电成本约为38%;而实际上,由于单罐工质的循环使得换热器出力下降,必须采用电加热器方可保证工艺运行,实际节省用电成本为25%左右,经济性良好。本文为储能技术在纺织工业的应用和设计方法提供支持。

Abstract:

Electricity costs are the second largest production cost in the nonwoven fiber process. A key measure is how to reduce electricity costs and improve profitability. Based on the power consumption strategy of "peak valley flat price" implemented by the state to encourage peak shaving and valley filling of electric power, a single-tank energy storage and heat exchange system for fiber sizing based on energy storage technology is proposed in this paper, and the design methodology of its key parts is described. Combined with the application case of a textile enterprise in Hebei, the economy of the system is analyzed. Through theoretical calculation, using the proposed energy storage heat exchange system can reduce electricity costs by approximately 38% compared to convention fiber heating devices. Due to the cycle of the single pot working medium heat exchanger output drop, must use electric heater can guarantee the process operation, actual saving electricity costs about 25%, which is good economical. This paper also provides support for the application and design methodology of energy storage technology in the textile industry.
