Innovative application technology in cotton textile industry - energy, power system optimization

In recent years, China Cotton Textile Industry Association (hereinafter referred to as “China Cotton Association”) has continued to carry out energy conservation and emission reduction technologies and project collection and recommendation activities in the cotton textile industry, collecting energy conservation, emission reduction, clean production and resource recycling in the cotton textile industry. Use technology and application with mature technology, good economy and practicability; release “China Cotton Textile Industry Energy Conservation and Emission Reduction Technology and Application Catalogue” (hereinafter referred to as “Catalogue”) to promote energy conservation and emission reduction Work, reduce the production cost of enterprises, build an information sharing platform in the industry, and play the role of an excellent enterprise role model.

In 2018, the China Cotton Association released the sixth batch of "Catalogues". Some of the energy and power system optimization technologies are summarized below and introduced in the industry:

Low-frequency transformation of the negative pressure fan of the compact spinning machine: By reducing the operating frequency of the negative pressure fan of the spinning frame, the heat generated by the motor and the inverter is reduced, the power consumption is saved and the service life of the motor bearing is prolonged, and the transformation realizes the reduction of the production power of the spinning frame every year. About 2.6 million Kwh. The technology was developed and used by Shijiazhuang Changshan Beiming Technology Co., Ltd.

Compact spinning negative pressure fan transformation: the drafting compact unit adopts easy-disassembly type, which can easily switch between spinning compact spinning and ordinary spinning; the negative pressure unit adopts central airway central concentrated negative pressure form, main air duct and branch wind The pipe and tight pipe route is shortened, the negative pressure ventilation efficiency is improved, and the load and actual power of the negative pressure fan are reduced; the tight pipe adopts the double suction port form, the negative pressure is more balanced, the ventilation amount is increased, and the negative pressure air flow is smoother and greatly Reduce the negative pressure ingot difference, which is conducive to the consistent yarn index; the main negative pressure bellows is equipped with a wiper-type and circulating short-staple cleaning device to achieve long-term spinning negative pressure stability and long-term operation without spinning when the spinning is completed. Cashmere and waste cotton; equipped with a new structural grid ring with anti-blocking, anti-winding, non-sticking and self-cleaning functions, the spinning quality is more stable; the negative pressure fan reduces the motor power while maintaining the negative pressure. The energy saving effect is remarkable. The annual production of spinning frames is reduced by nearly 2 million Kwh. The technology is developed and used by Taikang Wanliyuan Cotton Industry Co., Ltd.
