Electric heating system of high-temperature asphalt tank

Abstract

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.

Description

technical field [0001] The invention belongs to the field of industrial electric heaters, and the technical solution of the invention is claimed. Background technique [0002] Traditional high-temperature asphalt tank heating devices use diesel or coal boilers to exchange heat for heat-conducting oil. The heat-conducting oil indirectly heats the asphalt. The heat transfer rate is low and there is pollution emission. The heat-conducting oil system has circulating pumps, burners and other equipment that will cause noise pollution. , If the combustion chamber of the traditional burner is improperly maintained, there will be a hidden danger of explosion, and the heating raw material is diesel or coal, which will cause fire hazards. The indirect heating of traditional heat transfer oil will cause "drip", "run", "take", "leak", " Diesel and coal are non-renewable resources, and the cost is high. It is difficult to supply sufficient and timely diesel oil when there is a shortage of...

[0002] Traditional high-temperature asphalt tank heating devices use diesel or coal boilers to exchange heat for heat-conducting oil. The heat-conducting oil indirectly heats the asphalt. The heat transfer rate is low and there is pollution emission. The heat-conducting oil system has circulating pumps, burners and other equipment that will cause noise pollution. , If the combustion chamber of the traditional burner is improperly maintained, there will be a hidden danger of explosion, and the heating raw material is diesel or coal, which will cause fire hazards. The indirect heating of traditional heat transfer oil will cause "drip", "run", "take", "leak", " Diesel and coal are non-renewable resources, and the cost is high. It is difficult to supply sufficient and timely diesel oil when there is a shortage of diesel oil. Indirect heating leads to a decrease in heat conversion rate, oil prices continue to rise, and heat transfer oil also has a service life limit. Regularly replaced, the cost of use increases year by year. The traditional indirect heat transfer oil heating is full of coils inside, which is very inconvenient for installation, maintenance, repair, and disassembly. The traditional indirect heat transfer oil heating needs to preheat the boiler in advance
