(Summary description)The textile industry is one of the high energy, water consumption and high pollution industries monitored by the state. The textile industry accounts for about 4.4% of the country’s total industrial energy consumption, 8.51% of the country’s total water consumption by industrial enterprises above designated size, and the country’s industrial wastewater. About 10% of the total emissions are one of the industries that consume a lot of energy in the manufacturing industry. It is also one of the industries that uses a lot of water, produces a large amount of waste water, and has a greater impact on environmental quality. In the textile industry, energy conservation and emission reduction are carried out in depth. Work is of great significance to the country, to the industry, and to the enterprise. In recent years, many textile companies have renewed their sewage treatment equipment and developed rapidly in the direction of energy conservation and environmental protection, actively using new energy-saving production equipment for technological transformation.

Dongguan Deyongjia Textile & Garment Co., Ltd. belongs to Hong Kong Deyongjia Group and is located in the strategic center of the Guangdong-Hong Kong-Macao Greater Bay Area. The company is large in scale, has world-class advanced production equipment and a strong technical team, and has a wide range of products. Deyongjia Company actively fulfills its social responsibilities, persists in the implementation of green production in all links, and always adheres to the development concept of "high quality and social responsibility". In recent years, Deyongjia has vigorously pursued the path of transformation and development and green development. Positive results have been achieved in reducing consumption, improving quality and increasing efficiency. In order to reduce the power consumption of fans, the impact of noise on the environment, and the frequency of fan failures, De Yongjia carried out technical transformations on the fans of sewage treatment plants twice in May 2018 and May 2019.
Before the technical transformation, the sewage treatment system was running 4 sets of 250kW centrifugal blowers. The nameplates and measured parameters of the blowers are shown in the table below.

Based on the actual production situation, Dongguan Deyongjia Textile replaced the original 4 centrifugal fans with 3 magnetic levitation centrifugal blowers of Magnetic Valley Technology CG/B220. The installation of the magnetic levitation fan is simple, and it can be installed only if the ground is flat, without the auxiliary installation of large cranes and other equipment.
The fan has passed the practical operation test and has the characteristics of high efficiency, low noise and stable operation. The outlet flow of the fan can be adjusted by frequency conversion according to the process requirements, which greatly saves power consumption and has achieved energy saving, noise reduction and environmental protection operation. purpose.
