Steam leakage reform program for garment manufacturing industry

Premier Li Keqiang March 21 hosted by energy conservation and addressing climate change conference to promote the implementation of the "Government Work Report" to promote energy conservation and low-carbon development, and research to address climate change related work.

This year's "Government Work Report" clarified the " hard task " of energy conservation and emission reduction , and it is necessary to eliminate backward production capacity of 27 million tons of steel , 42 million tons of cement , 35 million standard containers of flat glass , and ensure that the " Twelfth Five-Year Plan" elimination task is one year ahead of schedule. Completed, truly suppressed, will never rebound; increase energy conservation and emission reduction, control the total energy consumption, this year's energy consumption intensity should be reduced by more than 3.9% , sulfur dioxide, chemical oxygen demand emissions should be reduced by 2% .

It can be seen that reducing energy consumption and reducing environmental pollution are now important tasks for enterprises and corporate leadership.

A clothing company is mainly engaged in the import and export trade and expatriate labor services of textiles, clothing, electromechanical, light industry and chemical products. As a key enterprise group in Jiangsu Province, it has high requirements for energy conservation and environmental protection.

1.0 Clothing Industry Overview

The scale of China's garment industry is huge. Statistics show that China's garment industry has many worlds*, processing capacity*, production capacity*, export volume*, and export value*. In the processing of garments , the use of steam ironing is an indispensable process in garment processing. With the fuel, the price of coal is constantly being refreshed, and energy costs have become an important part of the production cost of the domestic apparel industry, which is mainly based on small profits but quick turnover. In order to reduce the initial investment, domestic small-scale garment enterprises characterized by labor-intensive use often ignore the initial construction of the steam system. As a result, the steam system is not perfect, the steam leakage is wasteful, and the long-term operation cost remains high. With the continuous introduction of foreign capital, the business philosophy of foreign-fashioned garment enterprises has gradually gained recognition from the industry, and gradually recognized the importance of the initial construction of the steam system. As a clothing export market in Jiangsu, Nantong is mainly sold to Japan, South Korea and Europe and the United States. Visionary business owners have begun to connect with the international market and produce high-quality clothing with advanced equipment. Although the initial investment is large, the long-term operating costs have been reduced, and the product quality has been improved and the international competition of products has been improved. force.

2.0 Clothing Enterprise Steam System Introduction

The steam system of the clothing enterprise is very simple. The steam mainly has three applications, the workshop is ironed, the workers live hot water, and the canteen processes the food. The boiler generates steam or heat pipe network to supply steam, enters the workshop sub-cylinder, and the sub-cylinder comes out through the pressure-reducing valve (if the pipe is long, the steam-water separator needs to be installed) to be sent to each ironing line. It is taken from the decompressed pipe to each iron, and a 1/4" trap is installed on each iron to remove the condensed water generated by ironing, and the condensed water return pipe is collected and discharged to the water tank. Among them, pressure reduction control and steam dryness control are very important. Firstly, the pressure reducing valve should function as pressure reducing and voltage regulation. The precise and stable pressure is very important for the temperature of the iron and the safety of the operator, because each The ironing temperature required for the fabric is different, and the temperature of the iron is actually controlled by the pressure of the steam. Therefore, the stable and precise pressure control actually ensures the temperature of the iron and ensures the ironing effect of the fabric. The safety of the first-line workers is not threatened. The dryness of the steam is another key factor in the quality of the ironing. If the steam line is not well drained, the iron will accumulate water, causing the temperature to be too low, and even the condensation water remains on the fabric. The product quality has been seriously affected. In order to eliminate this phenomenon, some companies simply remove the trap behind the iron, which is better, but it has caused Substantial leakage of steam. Rick steam trap, the steam can be effectively removed in the water, greatly improving the dryness fraction, to improve the heat transfer effect of downstream equipment.

3.0 Application examples of clothing enterprises

A medium and large-scale garment export processing enterprise, the company has 800 front-line employees . The first phase of the company's plant was small, and the steam system was not fully valued when it was first built. The energy cost of running it was high. During the construction of the new project, the customer introduced Rick's expertise and services in the steam system through a friend's introduction and hoped to get Rick's overall steam solution.

We worked with the design institute to complete the design of the steam system. The system consists of steam entering the company's sub-cylinder through the hot network pipeline, which is drained by the sub-cylinder and then sent to the production workshop, staff quarters, and staff canteen through three branches. A supervisor in the production workshop enters the secondary cylinder of the workshop through the pressure reducing valve, and separates each branch from the secondary cylinder of the workshop into each workshop. The steam pipeline may be long before the pipeline enters each workshop. Condensed water will be produced, and the Rake steam separator will be installed. It has been proved that the steam separator has achieved the effect of improving the steam dryness. After entering the workshop, many parallel branches are separated. The Rick float traps are installed at the end of each branch. The iron takes steam from the top of each branch to ensure the use effect. The system uses RAKE cut -off valves, ball valves, 25P steam pressure reducing valves, steam separators, and float traps. The director of the company responsible for the steam system, Hong Jinning, said that since the entire system uses Rick valves, the system design is reasonable, the steam decompression is very stable, and the use of the steam separator makes the steam entering each workshop very dry, greatly improving the ironing effect. There is no steam running and dripping in the system until now, and almost no maintenance is required, and the steam consumption of the whole plant is only about 0.5 tons / hour.

4.0 Conclusion

With the continuous improvement of China's export clothing grades, the quality of products will continue to increase. Enterprises are increasingly demanding the energy consumption of steam systems and the reliability of equipment. Rick is a specialist in steam control and energy conservation and clothing. Enterprises will be closer and cooperation will be more and more extensive. It also plays an important role in the effective application of energy and the protection of the environment!
