Huili Printing And Dyeing: "Low Carbon Account" In Energy Conservation And Emission Reduction

　　 In the eyes of many people, printing and dyeing enterprises are enterprises with high energy consumption. According to relevant policies, by 2011, the state will focus on eliminating nearly 7 billion 500 million meters of high energy consumption, high water consumption and low printing and dyeing capacity. The transformation and upgrading of printing and dyeing enterprises is imminent.

Many printing and dyeing enterprises in our region accelerate the pace of energy conservation and consumption reduction. In the 2009 annual energy saving advanced unit in Zhejiang this year, Huili printing and finishing Co., Ltd. is the only company in our district. Energy saving and emission reduction is not only a "cost revolution" for Huili printing and dyeing, but also a "industrial upgrading revolution" to enhance the overall competitiveness.

" Low carbon "Accounting books" help energy consumption pollution "double down"

Make full use of all available resources and save the resources that can be saved to the maximum. Huili printing and dyeing has its own "low carbon account" in saving energy and reducing consumption. Improving the technological process is an important part of Huili printing and dyeing "low carbon account book".

For example, cloth transported from textile mill to printing and dyeing plant needs to be desizing and bleaching before printing and dyeing. The earliest technology is to boil water through high temperature and strong caustic soda, consume water, consume energy, and consume alkali. Later, they improved the technology and used the high concentration of caustic soda and hydrogen peroxide to achieve the effect of desizing and bleaching, but this method increased the difficulty of sewage treatment. Today, Huili printing and dyeing has developed low alkali cold pad batch technology, which is in the leading position both inside and outside the country. It not only greatly reduces energy consumption, but also reduces the difficulty of sewage treatment.

In addition, the installation of energy-efficient equipment is to allow Huili printing and dyeing to save energy and reduce the cost of walking farther.

Sewage heat energy developed by Huili printing and dyeing recovery Installation. During the printing and dyeing process, the temperature of the sewage discharged from each washing part is as high as 90 degrees centigrade. After installing the sewage heat recovery device, the heat energy can be reused two times, and it can save 262 thousand and 100 tons of hot water in one year.

The improvement of the technological process and the updating and improvement of the production equipment reduce the energy consumption and pollution in the printing and dyeing process to the minimum and improve the quality of their products.

Energy saving and emission reduction boosted product upgrading

Energy saving and emission reduction for enterprises, the obvious benefit is the cost savings.

Fu Weirong, deputy general manager of Huili printing and dyeing, told reporters that in 2009, they passed technological innovation and equipment transformation. Over the past year, three energy saving costs of water, electricity and steam totaled over 438.5 yuan.

From the point of view of energy consumption of 10000 yuan output value, Huili printing and dyeing products are only 30.2 kilograms of standard coal per meter, and are in the leading position in the same industry in the whole province.

Through energy conservation Emission reduction Huili printing and dyeing not only gains visible economic benefits, but also further improves the product quality.

Huili printing and dyeing fabrics in 2009 reached 25 million meters, equivalent to 625 weeks around the earth. Among them, many products of Huili printing and dyeing are printing and dyeing services for the international fashion industry giants such as H&M and ZARA. For these giants of the fashion industry, they are concerned not only with the quality of quality products, but also with good production environment, including low energy consumption, environmental protection and so on. Huili printing and dyeing has made a contribution to the development of low carbon, which has been favored by these international giants.

Energy saving and emission reduction has brought Huili printing and dyeing onto the road of healthy development. Today, the content of Huili printing and dyeing "low carbon account book" is increasing. A project they are currently working on is reclaimed water reuse for printing and dyeing wastewater. Through advanced technology, the printing and dyeing wastewater produced in the production process is classified into advanced treatment and then used for production. By the end of this year, the biochemical and physicochemical two grade printing and dyeing wastewater pretreatment system with a total investment of more than 1500 yuan and a daily capacity of 5000 tons will be put into operation. It will be able to reuse more than 60% printing and dyeing wastewater. It can save 450 thousand tons of water every year, and the annual economic benefits can reach more than 300 million yuan.

Fu Weirong said that some enterprises regard energy conservation and emission reduction as a burden. Facts have proved that energy saving and emission reduction can bring a lot of economic benefits to enterprises, and it is also an important way for enterprises to transform and upgrade.
