How To Eliminate Backward Production Capacity In Textile Enterprises

In September 2nd, the leader of the state environmental protection department visited Changzhou Xu Rong knitting and dyeing Co., Ltd. to inspect the work of energy conservation and emission reduction.

Advocating green at present

In a sense, the elimination of backward production capacity by textile enterprises has created a rare opportunity for upstream equipment enterprises.

Changzhou Xu Rong - actively committed to

The cyanobacteria event in Taihu, Jiangsu in 2007 brought a great impact on the entire printing and dyeing industry in China. It changed the development mode of winning profits before sacrificing the environment, and many enterprises closed down after the incident.

Changzhou Xu Rong knitting and dyeing Co., Ltd. carried out the relocation and integration of factories at this time, and emphasized environmental protection requirements in the process of new plant construction, so that the company took the lead in the fierce market competition.

Xu Rong has greatly improved the production process and improved the production of water, electricity and gas by means of technological pformation. The production cost has been greatly reduced, energy consumption has been reduced, and significant economic benefits have been brought to the enterprise.

Its original cotton and OP (cotton and spandex blended) fabric dyed one bath method and polyester fabric dyeing and washing one bath method in saving water and electricity, at the same time, it brings efficiency improvement.

In terms of sewage treatment, Changzhou Xu Rong knitting and dyeing Co., Ltd. has invested in the construction of a sewage regulating sedimentation tank with a daily handling capacity of 800 tons.

In terms of production technology pformation, the company's orders are mainly cotton and cotton and spandex mixed fabrics, the traditional pretreatment process takes a long time, and uses a lot of chemical additives. After repeated attempts by the company's technicians, the dark colored series of these two products has been successfully produced by dyeing and bathing, which greatly reduces the production cost.

In addition, the shrinkage prevention machine and the shrinking machine are used for pre-treatment, so as to improve the production rate, reduce the abnormality and reduce waste.

The condensate and cooling water recovery system is used to recycle the positive and negative wash water in the process of soft water production. These methods have achieved significant water saving effect.

There are also the pformation of motor frequency and the use of air source heat pump units. With wind and solar street lamps replacing traditional street lamps and ordinary light bulbs in workshops, the energy saving of electric power can be saved by 200 thousand kilowatts per year.

The waste heat recovery from the boiler chimney is used to save 2850 tons of steam throughout the year.

The use of setting machine flue gas purification device, effectively reduces the particle concentration and oil smoke concentration.

Replacing heavy oil with natural gas can effectively reduce emissions of soot, sulphur dioxide and carbon oxides.

Huafu color spinning -- eliminating backward and accelerating upgrading

Huafu color spinning Limited by Share Ltd merger and reorganization of Fei Ya shares, instead of simply maintaining operations, but actively eliminating backward equipment: in order to achieve automation in the production process, to maximize color mixing effect and reduce workers' labor intensity, the company developed a HF1022 automatic mixer with Zhengzhou textile machinery Limited by Share Ltd, integrated the cleaning equipment, eliminated the old dust removal units, eliminated all more than 200 A spinning frames, eliminated all the 1332M slot machines, and added 7 sets of mixer, 15 sets of filter units, 53 sets of carding machines, 28 sets of drawing frames, and upgraded 165 sets of spinning machines and 31 sets of automatic winders.

Huafu color spinning has replaced the old dust removal unit as a new compound dust filter, which has greatly improved the environment and air dust content of the workshop, and has effectively improved the health and comfort of the staff working environment.

By replacing the A spinning frame, the stability and consistency of the product quality are improved by the replacement of the FA series of spinning frames.

By eliminating the slot machine, the automatic winding machine is replaced, so that the efficiency of the machine is raised by 30%, the labor intensity of workers is reduced, the quality of products is improved steadily, and the yarn free rate is 100%.

Through technological pformation, the technical level and automation level of the equipment have been greatly improved.

Ruyi dyeing and printing -- introducing advanced production equipment

In addition, Jining Ruyi printing and dyeing Co., Ltd. introduced advanced foreign special-purpose production equipment.

In early 2009, the company invested 27 million 400 thousand yuan to build 3 new production lines, and rebuilt and updated the high energy consuming equipment. 3 sets of new sewage heat exchangers and 3 sets of steam generators of the oil boiler flue were added. The total energy input was 24 million 110 thousand yuan, and the comprehensive energy consumption was reduced by 36%.

These enterprises are relatively well-known industry enterprises, and they have learned from the experience of eliminating backward production capacity, which has a good reference for enterprises in the industry.
