In the current trend of energy conservation and environmental protection, pharmaceutical companies should stop considering energy efficiency, environmental protection, and product quality when choosing dry equipment. Therefore, enhancing the energy-saving technology transformation of hot air circulation ovens has become a key issue of concern for related dry equipment enterprises. about
Hot air circulation ovenThe energy-saving methods are shared by relevant technical personnel as follows:
Improve the inlet air temperature of the hot air circulation oven and reduce the outlet exhaust gas temperature of the drying equipment. According to the introduction, improving the inlet air temperature of drying equipment is beneficial for improving the thermal efficiency of the oven. However, the inlet air temperature is limited by the allowable temperature of the product.
In a parallel flow oven, the surface temperature of the particles is relatively low, so the inlet air temperature of the drying equipment can be much higher than the allowable temperature of the product. Reduce various heat losses during the drying process. Generally speaking, the heat loss of a hot air circulation oven does not exceed 10%, while for large and medium-sized consumer installations with suitable insulation, the heat loss is around 5%. Therefore, it is very important to do a good job in dry and fragmented insulation tasks, but it is not necessarily better to have a thicker insulation layer, but to determine a better insulation layer thickness. The technician stated that in order to avoid dry and fragmented leaks, a series connection of supply fans and induced draft fans is commonly used; By making reasonable adjustments to operate the fragments in a zero pressure state, it can prevent the thermal efficiency of the hot air circulation oven from decreasing due to the leakage of dry media or the infiltration of ambient air& rdquo;
reduce
Hot air circulation ovenThe evaporation load. According to the introduction, before entering the hot air circulation oven, the material undergoes pre dehydration treatment such as filtration, centrifugal separation, or evaporator evaporation, which can add solid content to the material and reduce the evaporation load of the oven. This is one of the ineffective ways to save energy in drying equipment.
