Intelligent equipment makes the energy efficiency of the dye tank effectively improve, and digital technology makes the energy management of the shopping mall more and more sophisticated... With the rapid advancement of digital and intelligent transformation and upgrading, more and more industrial parks and large public buildings are implementing technological and management energy-saving renovation to achieve green and high-quality development.

According to the White paper "China's Energy Transition" released in August 2024, in the past decade, China has vigorously developed energy-saving and carbon reduction technologies and industries through industrial restructuring, optimization and upgrading, comprehensively improved energy efficiency, and continued to reduce energy intensity, saving energy consumption of about 1.4 billion tons of standard coal and reducing carbon dioxide emissions by about 3 billion tons.

It should also be noted that at present, the problems of high energy cost and low energy efficiency in China are still prominent. A number of experts recently interviewed by a reporter of Science and Technology Daily analyzed that accelerating the digital and intelligent transformation of energy can effectively improve the comprehensive utilization level of energy in the whole society and reduce the cost of enterprise investment and operation. "Smart change number turn" is making energy saving and carbon reduction become targeted.

In the cold winter, in the textile printing and dyeing workshop of Zhejiang Piyi Textile Co., LTD. (hereinafter referred to as "Zhejiang Piyi"), the dye cylinder running at high temperature continues to dissipate heat, and high temperature steam lingers throughout the workshop. This is the most important energy consumption link in the printing and dyeing industry.

Since 2022, the prices of all kinds of energy have continued to rise, and the cost of production energy has risen sharply. At the same time, affected by market factors such as foreign trade orders, the operating pressure of Zhejiang Piyi has surged, and the demand for energy saving and carbon reduction, cost reduction and efficiency improvement is very strong.

It was in this year that Zhejiang Piyi cooperated with ENN Energy Holding Co., LTD. (hereinafter referred to as "ENN Energy") to transform the dye cylinder process, changing part of the steam heat transfer process to the gas heater cycle heat transfer process, effectively improving the thermal efficiency of gas heating.

The energy-saving transformation is not only limited to the production process and process, the application of digital equipment makes it possible to accurately control the energy consumption of the dyeing cylinder.

In 2024, ENN Energy has successively installed a number of printing and dyeing plants with carbon intelligent control integrated machines, and the energy consumption management of dyeing tanks by various manufacturers has been further upgraded. Wang Zun, chief product officer of NENAO Panenergy Network, told reporters that the carbon intelligent control machine is independently developed by NENao Energy, and can use algorithms to sense, predict and analyze the microcirculation process system of the dye tank, and then optimize temperature control to achieve efficient matching of energy supply and printing and dyeing process.

The data show that the dye tank equipped with the carbon intelligent control machine has a 5% higher yield than before and remains above 99%. This means that the energy consumption of a dyeing tank can be reduced by about 4%.

"We also set up a carbon emission factor monitoring module in the integrated carbon intelligent control machine, which can automatically calculate the carbon footprint of the entire production process of printing and dyeing, and intelligent carbon footprint analysis report for printing and dyeing products." Wang said that credible carbon footprint reports will play an important role in China's textile exports.
