High efficiency fan
As a major industrial and energy province, Hebei Province actively responds to the call for energy conservation. In order to promote the smooth development of the 13th Five-Year Plan, the industrial sector has implemented "controlling total volume, promoting transformation, focusing on technological transformation, promoting energy conservation, focusing on management, and promoting efficiency". Important measures. As an important production base of high-quality plate and high-quality bar and wire rod in China, Handan Iron and Steel Group Hanbaoshan Iron and Steel Co., Ltd. is facing the problems of aging equipment and low fan operation efficiency, so technological upgrading and fan transformation are imminent. At this time, Ruichen Environmental Protection undertook the renovation of the supporting environmental dust removal fan for the 2x 360 m sintering machine of Handan Baosteel Iron Co., Ltd. and completed it beyond the standard, which was affirmed by Handan Baosteel Iron Co., Ltd.

At the beginning of 2016, the 2# coke oven of Huaigang was overhauled. In order to meet the environmental protection requirements, the dust removal fan needs to be modified. According to the calculation of the design institute, the air volume has increased from 190000 m3/h to 260000 m3/h, and the motor has changed from 560kW to 710kW. Therefore, it is necessary to purchase fans, motors, frequency converters, etc. again, and to rebuild the civil foundation, which takes at least 7 days, affecting production. However, our company only needs to customize a "Rui Chang" high-efficiency and energy-saving fan to meet the needs.

Fan Energy Saving Technical Transformation Project of Lianyungang Xingxin Iron and Steel Co., Ltd.
The original dust removal fan of Xingxin Iron and Steel 3# out of the iron yard has poor dust removal effect. In order to respond to the national environmental protection call, after comprehensive consideration, Xingxin Iron and Steel decided to use our high-efficiency and energy-saving fans, increase the air volume and air pressure design, and require that the operating efficiency of the modified fans shall not be less than 80%. In early September 2017, Shanghai Rychen completed the installation of the new fan. After a period of operation, the two parties organized the acceptance, and the operating efficiency reached more than 81%, and the project was perfectly accepted.

This renovation is aimed at two tail dust removal fans in the first burning workshop. The original 1# and 2# tail dust removal fans have low operating efficiency of 60.76 and 60.67 respectively, which cannot meet the production requirements. The manufacturer requires the use of existing electrical equipment to transform two fans to maximize the operating air volume and air pressure of the fans.

Southern Cement Co., Ltd. Fan Energy Saving Technical Transformation Project
Jiangxi Southern Cement responded to the national call for environmental protection, reduced dust emissions, and replaced the original electric dust removal equipment at the kiln end of each branch plant with bag dust removal equipment. The system resistance will increase by 1000Pa to 1500Pa. Shanghai Rychen adopts high-efficiency fluid conveying technology and customized "Rui Chang" high-efficiency energy-saving fan, which can not only meet the need of increasing wind pressure after changing electric bags, but also effectively reduce the increase of production cost. After technological transformation, the operating efficiency of the three high-efficiency fans is higher than 80%, and the increase in power consumption per ton is lower than 1.5kWh, meeting the requirements of Southern Group.

Hebei Jinyu Dingxin Cement Co., Ltd. Coal Mill Fan Reconstruction Project
The operating efficiency of the original 4000t/d coal mill fan is 68.8%, and the operating efficiency is low. In order to improve the air volume, the original fan needs to be technically modified. After the renovation of our company, the flow rate has been greatly improved compared with that before the renovation, the equipment is stable in operation, and the fan operation efficiency has reached 82.7, which has been unanimously recognized by the senior management and leaders of Jinyu Dingxin.
