Pay attention to energy use management and promote energy saving and long-term harvest

The main products of Yixing Loki are textiles, corduroy, khaki printed dyed fabrics, denim and so on. At present, there are new and old plant heat 50t/h and denim hot 30.4t/h, which are used in the central heating of Yixing union thermal power plant. The cogeneration mode is adopted, which greatly improves the energy utilization ratio and improves the environment.

However, since the Yixing cogeneration power plant is heating the whole city of Yixing, the parameters of the heat network are as high as 1.6MPa, while Yixing Loki mainly uses heat of 0.5Mpa and 0.7Mpa steam. The company is only 2 km away from Yixing union thermal power plant. The larger steam pressure difference is urgently needed to build a differential thermal power project to realize the comprehensive utilization of resources.

Yixing Lok Chi responded positively to the policy of national energy conservation and pformation, tap the potential internally, improve the system, and pform irrational heating systems.

Therefore, Yixing Lok Chi invested 2 million 60 thousand yuan in 2012, and installed a set of DCS decentralized remote automatic control system on each machine platform to achieve the remote control and control of steam pressure, temperature and flow rate.

After the completion of the project, the workshop can save 3~5 tons of steam per hour, save 20 thousand tons of steam per year, and save 4 million 320 thousand yuan in economic efficiency.

New thinking of Process Technology Cryogenic Cold reactor pretreatment process

All along, cotton fabric pretreatment, mostly using the traditional desizing, scouring and bleaching processes, the advantage of this process is thorough pretreatment, good cloth effect, but because the process is accompanied by multi-channel high temperature steaming, high temperature washing, resulting in the working environment high temperature, high humidity and long process, high consumption of water and electricity consumption, high production costs.

Lok has been exploring new technologies for energy saving and emission reduction in recent years. One of the most important aspects is to use low-temperature cold reactor pretreatment, through heavy cold reactors, light bleaching or even bleaching, and only through simple water washing to complete all processes of pretreatment, cooking, and bleaching. Low carbon processing technology greatly reduces the amount of steam and saves manpower and water and electricity costs; low temperature cold reactor pretreatment has subverted the traditional pre-treatment of high temperature and high alkali technology.

At low temperature, the mild treatment environment makes the treated fabric less damaged and less weightless without affecting the pretreatment quality.

Low temperature pretreatment is an inevitable trend in the future.

Due to the selection of suitable products and a large number of laboratory test work, the final cryogenic cold reactor pretreatment process has achieved the desired effect. Through comparison with the traditional cold pile plus high temperature loose type boiling and bleaching process, the indexes basically meet the requirements of subsequent dyeing. This process can save long car steaming and boiling process, save 7000 tons per year, save electricity by 240 thousand degrees, save water 36 thousand tons, and save 1 million 680 thousand yuan annually.
