Comprehensive analysis of thermal oil heating bitumen tank technology | FEITENG

Working principle and technical details

The working principle of thermal oil heating bitumen tank is based on the concept of heat conduction and circulation heating. The system mainly consists of thermal oil heating furnace, thermal oil circulation pump, heating tank, storage tank, transportation pipeline and operation control system. During the heating process, the thermal oil is heated to a certain temperature in the heating furnace, and then driven by the thermal oil circulation pump and circulated in the closed piping system to transfer the heat to the asphalt in the asphalt heating tank. After heat exchange, the heat transfer oil with reduced temperature returns to the heating furnace for heating again, forming a closed loop.

In order to ensure the uniformity of asphalt heating and avoid localized overheating or overcooling, the temperature of the asphalt in the heating tank is precisely controlled by advanced temperature control devices. These control devices can monitor the asphalt temperature in real time and automatically adjust the heating power according to the set temperature range to ensure that the asphalt is uniformly heated within the specified temperature range.

The advantages of thermal oil heating asphalt

Thermal oil heating asphalt has significant advantages over traditional steam heating. First of all, it can be in the lower working pressure to obtain a higher temperature heating effect, reducing the pressure level of the equipment and engineering costs. Secondly, thermal oil heating is closed-circuit heating, which can fully utilize waste heat, reduce heat loss and improve thermal efficiency. In addition, thermal oil heating also has the advantages of fast heating speed, precise temperature control and easy operation.

In the asphalt heating process, the use of thermal oil to avoid the asphalt due to direct heating and possible aging deterioration. The maximum temperature of heat transfer oil can reach 300 ℃, can meet the needs of asphalt heating, while avoiding too high a temperature on the asphalt quality. In addition, the process of heating asphalt with heat transfer oil is a fully closed system, which reduces heat loss and environmental pollution.

Application scenarios and market demand
