Cleaning Technology

at present, the three-dimensional cleaning machine involved in tank car cleaning technology in China has full-automatic function, which includes two main structures: three-dimensional positioning machine and high-pressure cleaning machine. However, the tank car cleaning process used in the railway field still has many shortcomings. For example, serious pollution, serious energy consumption, insecurity, etc. In order to improve such defects, it is necessary to introduce new processes and improve the previous cleaning processes. The introduction of new technology can reduce environmental pollution and save capital cost. It can adapt to the development of the times and meet people's needs. Therefore, this paper expounds and analyzes the high-pressure water jet cleaning technology in railway tank cars from the aspects of application and improvement, and puts forward the corresponding improvement measures for reference.

Macroscopic Parameters

The computational fluid dynamics (CFD) model has been used to investigate the two-phase flow phenomena such as high-pressure water jet. High-pressure water jet is a new technology and develops rapidly due to its advantages in recent years. In this research, the effects of different models on the macroscopic parameters of jet propagation characteristics of high pressure water jet have been investigated numerically through the CFD technique. The simulations of the water jet with three kinds of k-ε models (i.e., standard, RNG, and realizable k-ε models) have been compared under the same conditions. It may be concluded that, the results calculated by the realizable k-epsilon model agree well with the experiment data and the realizable k-epsilon model would be utilized in the latter simulation. The agreement of the predicted data and experimental data are quite reasonable, it demonstrates that the CFD technique can be successfully applied to high-pressure water jet.

High Pressure Water Jet

In order to identify target material and physical dimension quickly and effectively by utilizing high pressure water-jet, the equal eigenvalues of reflected sound signal is required when high pressure water-jet impulse the same target through array nozzles. It is necessary to research the reasonable structure for flow divider to ensure that pressure and flow of every nozzle are identical. According to the device structure size, basic structure of flow divider and pipeline connection request, structure parameters of flow divider were acquired and introduced in this paper. The required initial parameters were calculated on demand, and the inside fluid state of flow divider was also judged. The governing equations are developed by combining incompressible viscous fluid continuity equation with N-S equation and standard k-ε turbulence model. Structure parameters were optimized by combining fluent with the orthogonal experiment. Through the comparison of pressure and flow data acquired in the analysis of the inside flow field of the flow divider, maximum relative pressure deviation of nine channels that based on the optimal size is 0.0243% and maximum relative deviation of the mass flow is 0.0000187%. The requirements of pressure and flow uniformity for identifying target material by using high pressure water-jet and multiple nozzles can be met perfectively.

High Pressure Water Jet

The traditional grinding technology of ball mill has many problems, such as high energy consumption, unable to maintain the original crystal shape, and it is difficult to obtain high quality and high purity ultrafine powder. The high-pressure water jet mineral dissociation technology is a new technology which is developed in response to these requirements. The experiment shows that the water jet technology has a strong ability of ultrafine grinding. With the increase of jet velocity, the crushing effect is more obvious. The high-pressure water jet pulverization is superior to ball milling for the separation of rare earth minerals, which has the characteristics of high dissociation degree and relatively uniform particle size. The water jet pulverization is more beneficial to the separation and recovery of rare earth minerals.
