Compressed air is increasingly used in modern industry due to its safety and convenience. Modern industry requires high reliability and civilized production, as a result, more and more customers need oil-free, dust-free purified compressed air, it takes energy to purify compressed air, the largest energy-consuming device in a purification plant is an air dryer, air dryers have two major categories: adsorption dryers and refrigerated dryers, this paper revolves around a new type of zero gas consumption residual heat regenerative air dryer, a comparative analysis of the energy consumption of various air dryers, provide the basis for the user's selection.
The effective air supply of the refrigerated dryer can reach 100%, however, due to the limitations of the cooling principle, the dew point of the gas supply for a refrigerated dryer can only reach a temperature of about 3°C ??(pressure dew point), and it is greatly affected by the intake air temperature, for every 5°C increase in inlet air temperature, cooling efficiency drops by 30%, the supply dew point will increase significantly, the traditional adsorption dryer consumes gas and consumes electricity, in a nutshell, energy consumption is higher than that of refrigeration dryers, but it has the irreplaceable advantages of a refrigerated dryer: the gas supply dew point is low and stable.
Jiangsu Jiayu Regeneration Dryer, use the heat generated when the gas is compressed, directly heat the adsorbent in the drying tower and allow it to desorb. We know no matter what the compressor is,
When the gas is compressed, it generates a lot of heat of compression, therefore, after the compressor compresses the gas, it must be equipped with a cooler to cool the gas to room temperature, then it is sent to the back-end equipment for drying, in this way, a lot of heat energy is wasted, the waste heat regeneration dryer utilizes this part of energy, the heating regeneration does not consume compressed air, only 1% of dry compressed air is consumed during cold blowing, full use of the compressor's residual heat to complete the regeneration of the adsorbent (the compressor can also eliminate the last-stage cooler), no blowers and electric heaters are needed,70% energy savings in the energy crisis today, it is indeed an ideal energy-efficient dryer. Jiangsu Jiayu JRR series waste heat regeneration air dryer, it is a new generation of dryer designed on the basis of adsorption dryer, which is more efficient and energy-saving.
Under the same working conditions, the use of waste heat to regenerate the dryer costs less than a freezer dryer, overturned the traditional concept. Refrigerated dryers consume less energy than adsorptive dryers, the zero-gas-consuming heat recovery dryer is almost energy-inefficient and the most energy-saving model. Based on the heating regeneration dryer, the refrigeration dryer saves energy by 56%, the waste heat regeneration dryer saves energy by 70.4%, and the zero gas consumption waste heat regeneration dryer saves 88%, such a large energy-saving effect is worth our vigorous promotion, long-term use of waste heat regeneration dryer, users can obtain greater economic benefits from energy conservation, people can also gain greater social benefits.
