2090-CSWM1DF-14AA09 The Paper Industry “14th Five-Year Plan” and Medium – and Long-term High-quality Development Outline issued by the China Paper Association put forward the sustainable development goals of the paper industry during the 14th Five-Year Plan period. Due to the country’s per capita paper consumption will continue to increase before the national economy reaches the medium-developed countries, as well as the impact of the carbon peak and the implementation of the ban on waste paper import policy, the total energy consumption of the paper industry will continue to rise, and the demand for papermaking related equipment will also increase.

Turbine fan

The application of turbine fans in China’s paper industry is relatively late, and it has been officially put into use since 2007, and the relevant technicians in the paper industry know little about it, and it is often regarded as a “new technology”. The turbine fan has the advantage of high mechanical efficiency and can save energy consumption of equipment. In addition, the exhaust temperature of the turbine fan is high, generally 120 ~ 180 ° C, and the heat can be recycled for the heating of 2090-CSWM1DF-14AA09 the paper machine white water and air system. And the turbine fan does not need to use water as the working fluid, which can save water.

01 Customer Demand

With the increasing use of turbine fans, the demand has increased significantly, and the performance of papermaking equipment has also been continuously improved, developing in the direction of low energy consumption, high yield and high output. A customer of a paper company in Zhejiang Province pre-reformed and upgraded its production equipment on site, improved the process, and achieved production efficiency improvement and energy saving and consumption reduction as the direction of the transformation.

02 Inwitten Solution

2090-CSWM1DF-14AA09 In order to meet the needs of customers, Inweiten uses GD270 inverter to adjust the motor operating frequency. GD270 has the product advantage of free parking + speed tracking, so as to control the fan running speed and meet the requirements of wind pressure. At the same time, according to the production process, reasonable adjustment of the inverter operation mode makes the production efficiency and energy saving effect greatly improved.

03 Customer Revenue

1. Equipment cost: inverter chooses P-type machine corresponding motor power, saving equipment cost;

2. Production efficiency: It can realize rapid acceleration and deceleration, and increase the fan speed to the working frequency in a short time;

3. Energy saving effect: free parking inverter stops output, and tracks start 2090-CSWM1DF-14AA09 when starting again, which can save standby operation and achieve energy saving.

04 Summary

At present, the paper industry is increasing energy-saving transformation in terms of adhering to energy conservation and emission reduction; In terms of improving product quality, it is required to innovate and transform process technology and equipment. In order to ensure the continuity and stability of production, Inwizen is committed to improving the level of production equipment and processing equipment for pulp and paper products, and promoting the industrial upgrading and development with lean production.
