The invention relates to an
electric heating system of a high-temperature
asphalt tank. The defects that (1) the heat conversion rate of indirect heating is low; (2)
noise pollution,
waste gas pollution and environmental
pollution are caused; (3) potential safety hazards such as explosion and leakage happen; (4) using cost is increased year by year; (5) mounting, maintaining and repairing are inconvenient; (6) work can not be conducted in the oil shortage process in the prior art are overcome. According to the
electric heating system of the high-temperature
asphalt tank, the side face of the tank body part is provided with an electric heater part through a
flange, a power wiring box part of an electric heater is used for leading in a power source, a
power cable is used for being connected with multiple
electric heating elements, and the electric heating elements have a heating function.
Petroleum is non-renewable resources, according to
Yearbook, up to the end of 2011, the global
petroleum reserves are about 1.653 trillion buckets, and the global
petroleum reserves can be used for 54 years. Last year, the British
Petroleum Company reported that the global
petroleum reserves are 1.526 trillion buckets by the end of 2010. According to the very conservative consumption speed of global 0.8 hundred million buckets every day, the current global petroleum reserves can be globally consumed for 54 years. A road building
machine is a device which consumes a large number of petroleum products, the heat conversion rate is low, if all road building machines in China or even in the whole world are changed to be in a direct electric heating mode, the heat conversion rate can be greatly improved, pollution is lowered, and petroleum resources are saved.
