Printing and dyeing enterprises in Keqiao District comprehensively promote green and low-carbon development

Recently I walked into Zhejiang Red Green Blue Textile Printing and Dyeing Co., Ltd. located in Ma’an Street and saw a large area of solar photovoltaic panels installed on the roof of its factory. “When the sun is good, these electric panels generate more than 50,000 kilowatt-hours of electricity every day, and each kilowatt-hour of electricity can save the company more than 1 cent in electricity bills.” Mo Linxiang, the company’s executive deputy general manager, said that compared with the traditional model, the company provides The roof of the factory cooperates with a third party to use solar power to generate electricity. It is not only the use of clean energy, but also a way for enterprises to practice green development and contribute to “carbon neutrality”. Currently, the company’s roofs that can install solar photovoltaic panels have all been installed. .

In Ma’an Street, printing and dyeing enterprises that use solar photovoltaic power generation like “Red Green Blue Textile” are not an exception. Currently, there are “Red Green Blue Textile” and “Zhonghuan Textile” More than 10 companies including “Printing and Dyeing” took the lead in taking the lead, saving about 3-5% of electricity consumption according to the installed capacity.

In addition to using clean energy at the source, printing and dyeing companies also actively use existing energy to achieve recycling. At present, more than 100 printing and dyeing enterprises in Ma’an Street have basically installed waste heat reuse systems. Through waste heat reuse, they can realize cascade utilization of energy and effectively improve energy utilization.

In Shaoxing Yongtong Printing Co., Ltd., the company’s waste heat recovery rate reaches more than 90%. “On the one hand, we transport the waste heat generated by the medium-pressure steam of the setting machine to related equipment.” Zhang Jianmu, general manager of the company, said. On the other hand, through machine modification, we also convert part of the medium-pressure steam into low-pressure steam and provide it to related parties. equipment. At the same time, the waste heat generated by low-pressure steam is also fully recovered and utilized.

With the transformation and upgrading of Keqiao’s printing and dyeing industry, the environmental protection concepts of printing and dyeing enterprises have also been continuously improved in recent years. More and more companies plan to improve energy efficiency through energy-saving technological transformation. For example, “Xinshu Printing and Dyeing” plans to invest heavily in transforming motors and replacing ordinary motors with permanent magnet motors year by year. It is expected to increase the power efficiency of the equipment by about 15%.

“In recent years, Keqiao District has actively promoted the overall improvement of printing and dyeing enterprises, helping the printing and dyeing industry to develop into high-tech, intelligent and green. Next, we will further Guide more printing and dyeing enterprises to optimize their energy structure, use energy in a cascade, and innovate process technology to help create a green and low-carbon printing and dyeing industry cluster.” said the relevant person in charge of Ma’an Street.
