The energy consumption level of polyester staple fiber equipment is an important consideration, which directly affects the production cost and the economic benefits of the enterprise. The following is a detailed analysis of the energy consumption level of polyester staple fiber equipment:
I. Energy consumption composition
The energy consumption of polyester staple fiber equipment is mainly composed of the following parts: steam consumption, electricity consumption, chilled water consumption and consumption of other energy media, such as compressed air, circulating water, etc. According to the information in the reference article, steam and electricity are the main parts of the energy consumption of polyester staple fiber equipment, and the two together account for more than 90% of the total energy consumption.
Steam consumption: In the production of polyester staple fibers, steam is mainly used to heat the rollers of the tension heat setting machine to meet the tension heat setting process requirements. The steam consumption will vary according to the different configurations and process requirements of the production line. Generally speaking, high-pressure steam (such as 3.5MPa) has a higher consumption ratio and accounts for a larger proportion of the comprehensive energy consumption of the device.
Electric energy consumption: The electric equipment transmission, lighting equipment and control system in polyester staple fiber equipment all consume electric energy. Especially in recent years, with the improvement of equipment automation and intelligence level, the proportion of electric energy consumption in total energy consumption is also gradually increasing.
2. Energy consumption level
The energy consumption level of polyester staple fiber equipment is affected by many factors, such as equipment model, production capacity, process parameters, raw material quality and operation management level. Taking a 100kt/a polyester staple fiber device as an example, after energy optimization measures, its unit product comprehensive energy consumption dropped from 4812.3MJ/t before optimization to 4240.0MJ/t, a decrease of 11.89%. This shows that the energy consumption level of polyester staple fiber equipment can be effectively reduced through technological transformation and process optimization.
3. Energy-saving measures
In order to reduce the energy consumption level of polyester staple fiber equipment, the following energy-saving measures can be taken:
Recycling of steam condensate: By recycling steam condensate, the steam utilization efficiency is improved and steam consumption is reduced.
Electric energy optimization: Measures such as installing harmonic absorbers and replacing lighting strips can be taken to reduce electric energy consumption.
Optimization of compressed air energy consumption points: By optimizing compressed air energy consumption points, the compressed air consumption can be reduced.
Air conditioning transformation and seasonal differentiated operation: Through air conditioning transformation and seasonal differentiated operation, the consumption of chilled water, steam and electricity can be saved.
In summary, the energy consumption level of Polyester staple fiber equipment is affected by many factors, but through technical transformation, process optimization and energy-saving measures, the energy consumption level of equipment can be effectively reduced, and production efficiency and economic benefits can be improved.
