In today's society, “green environmental protection†and “energy saving and consumption reduction†have become global topics and have been listed by consumers as an important consideration in selecting products. For this reason, many companies have taken the lead in the development of green machinery products. Vacuum drying equipment is favored by customers because of its "green equipment."
With the severe invasion of haze days, the society must pay attention to the strategic viewpoints of energy conservation, emission reduction, sustainable development, environmental protection, and conservation-oriented society in today's society. In addition, energy shortages have attracted worldwide attention, and the traditional concept believes that the vacuum drying equipment has high energy consumption because it requires a vacuum pump. However, there was no real comparison of energy consumption when the same material was dried to the same moisture content. In fact, vacuum drying is drying at a low temperature in an enclosed space, and energy waste is relatively small.
Despite this, the energy saving of vacuum drying equipment is still the key to development. Compared with other types of drying equipment, the energy saving of vacuum drying equipment should focus on the rational design, selection and use of vacuum systems.
There are not many vacuum systems capable of pumping steam. At present, there are two main categories. One is a pump capable of directly pumping water vapor. The main ones are water jet pumps, steam jet pumps, water ring pumps, and wet roots pumps; It is using condensation to catch water. Both of these methods consume relatively high energy. The direction of the former type of energy saving should be to increase the pumping efficiency of the pump; the latter type of energy saving should be directed to the design of the structure and thermal efficiency of the gas-solid phase changer.
Continuous vacuum drying equipment is an important way to increase product output and save energy. The continuous vacuum drying equipment has less auxiliary time than the periodic vacuum drying equipment, which saves time and increases the output. At the same time, he does not need to change the temperature of the equipment every time it produces a cycle like the periodic vacuum drying equipment, which causes part of the energy to be wasted on the repeated heating of the equipment components. Therefore, energy is saved.
Industry insiders pointed out that domestic companies have accelerated the study of vacuum drying technology, which has reduced energy consumption to a certain extent, reduced pollution, brought more benefits and value to society, and made due contribution to the realization of green production and low-carbon production. contribution. At this stage, however, the vacuum dryer revolution in China has not yet been successful. Vacuum drying equipment manufacturers generally have low innovation capabilities. Poor enterprises that can introduce new technologies and new products with independent intellectual property rights have resulted in slow development of drying technologies. Knowledge achievements have not been effectively translated into actual productivity. At present, the R&D and innovation of technologies in the field of drying equipment mainly rely on universities and research institutes. Due to the disconnection of companies, it is difficult to effectively turn knowledge achievements into productivity.
It can be seen that in this regard, China's relevant enterprises should carry out comprehensive, multi-level energy-saving technological transformation, vigorously develop the application of renewable energy and industrial waste heat drying technology, and comprehensively promote China's vacuum drying technology reform and application.
Xiao Bian believes that the trend toward the development of energy-saving vacuum dryers is a topic worthy of study by many manufacturers. If energy-saving products can be better used, sales of products will become a trend of increase, and users can also Which gets higher profits, so that energy-saving development will be the dryer industry's innovation.
