Design a Laboratory Rotating Test Bench for the Multi-Channel Dryer Experiment
Sha Wang,Jixian Dong,Changke Tan,Bo Wang,Lijie Qiao,Huan Liu 한국펄프·종이공학회 2019 펄프.종이기술 Vol.51 No.5
The dryer of paper machine has problem in discharging condensate water. When the dryer rotates at a high speed, the condensate water that is not discharged in time will form a water ring, resulting in low drying efficiency and high energy consumption. Thus, based on the multi-channel dryer proposed by others, a series of experiments was carried out on multi-channel dryer under static condition. However, due to the fact that the research condition of condensation and heat transfer of multi-channel dryer is not exactly the same as the actual working condition, the multi-channel dryer has not been introduced to the market. To address the above problems, this paper presented a rotating test bench which can better simulate the actual working condition of dryer and expounded the working principle of the test bench, as well as the design and calculation of rotary device of the test bench. Finite element analysis software was used to analyze the stress on the dryer channel. In order to avoid resonance problems, modal numerical analysis was conducted on the test bench, which provided experimental conditions for the further study of multi-channel dryer.
