Abstract (English):
Thermal energy is the most common, and important type of energy used. At present, the efficient use and management of thermal energy is very important and provides an effective way to combat the energy crisis. With stricter emission regulations and rising fossil fuel prices, energy conservation and emission reduction have become especially important for any heat-based distillation process. Currently, energy-saving methods include the use of columns with a partition wall or other configurations. Using thermal rectification technology can play a positive role in promoting the development and use of clean energy and reducing carbon dioxide emissions. Energy-saving methods mainly used to improve rectification include heat pump technology, Rankine cycle, Stirling engine and others. The purpose of the work is to investigate the operation of the engine because of cyclic compression and expansion of air or other gas at different temperatures. It is used to drive a fan in industrial steam condensation processes from a distillation column. The fan can promote vapor condensation, improving heat transfer and process efficiency. The other part of the engine must be cooled to create a temperature gradient. This can be achieved by using a coolant. The water first passes through the cold part of the engine, and then is injected into the air stream, which the fan pumps through an air condenser. The results showed that water injection makes it possible to reduce the air temperature more effectively, which contributes to better condensation of liquid vapors from the distillation column.
