Analysis of factors affecting energy consumption of Paraffin forming machine
1 Raw material factors
The raw material of the paraffin forming machine is refined liquid wax produced from the hydrorefining unit.
According to actual production conditions, semi-refined wax is usually less effective in demoulding than fully-refined wax. If demoulding difficulties occur, it will directly affect the decrease in processing capacity of the device and increase energy consumption.
According to the paraffin crystallization theory, when the wax liquid is extremely cold at high temperatures, the wax with a high melting point will precipitate first and generate a large number of crystallization centers, resulting in the formation of dense needle-shaped crystals, which adhere tightly to the wax disk, making demoulding difficult. In addition, the higher the isomeric hydrocarbon content of paraffin wax, the higher its methyl content, and the shrinkage rate of paraffin wax is related to its methyl content, and the greater the methyl content, the smaller the shrinkage rate, and the smaller the shrinkage rate will also increase the demoulding. difficulty. In order to pursue the yield, the pre-processing device makes the distribution of paraffin carbon components wider and the content of isomeric hydrocarbons higher, which results in poor demoulding effect of semi-refined wax. When processing fully refined wax, since the fully refined wax is processed by the ketone-benzene device, the carbon components are concentrated and the isomeric hydrocarbon content is very small, which is easy to cool, solidify and crystallize.
2 Mechanical failure factors
Long-term smooth operation is the key to energy conservation and emission reduction. Due to the characteristics of the paraffin molding machine, there are many rotating equipment and there are relatively many mechanical failures.
Therefore, equipment failure rate directly affects device output and energy-saving efforts.
Strengthening equipment maintenance capabilities and operator inspection quality are the key to reducing equipment mechanical failures.
