How does the environmental protection dryer achieve the advantages of high efficiency and energy saving?

2020-03-02

Every eco-friendly dryer user wants to achieve efficient eco-friendly dryer operation and minimize losses. As a professional manufacturer of environmental protection dryers, Chuangda gives the following suggestions.

First, pay attention to the use of cooling water. The fans and pumps used in environmentally-friendly dryers are large-scale equipment, and the fans basically run continuously, so the motors they use are easy to generate heat, and water is used to cool them. However, as environmental problems become more serious today, water is also a scarce resource. User friends are advised to recycle the cooling water, which not only reduces the loss, but also saves water.

Second, pay attention to the overall insulation of environmental protection dryer. The drying work mainly uses thermal energy, so the full use of thermal energy has become a very important one. Therefore, special attention should be paid to the heat preservation work of the environmental protection dryer. No heat loss can occur in any link.

The heat pump drying unit is mainly composed of a finned evaporator, a compressor, a finned condenser, and a throttle valve. It allows the working fluid to continuously evaporate and absorb the heat from the outdoor environment (or the water vapor in the drying room) → The thermal cycling process of compression → condensation (releasing heat in the indoor drying room) → throttling → re-evaporation, so that the heat in the external low temperature environment (or the water vapor in the drying room) is transferred to the drying room. The compressor circulates in the system. It completes the gaseous step-up and temperature rise process in the compressor (temperature up to 100 ℃). It enters the internal machine and releases high-temperature heat to heat and dry the air in the room. At the same time, it is cooled and converted into a liquid state when it runs to the external machine. After that, the liquid quickly absorbs heat and evaporates again to turn into a gaseous state. At the same time, the temperature can drop to -20 ° C to -30 ° C. At this time, the air around the heat sink will continuously transfer heat to the refrigerant.
