Description

Technical Field

[0001] The utility model relates to the field of heating equipment, in particular to a novel low-energy consumption high-temperature oil furnace. Background Art

[0002] The working principle of the thermal oil furnace is to transfer heat through the heating elements immersed in thermal oil. With thermal oil as the medium, a circulating pump is used to force the thermal oil to circulate in the liquid phase, and the heat is transferred to one or more heat-using equipment. After unloading from the heat-using equipment, the heat is returned to the heater through the circulating pump, and then the heat is absorbed and transferred to the heat-using equipment. This cycle is repeated to achieve continuous heat transfer and increase the temperature of the heated object. It can be widely used in industrial fields such as petroleum, chemical, pharmaceutical, textile printing and dyeing, light industry, and building materials. However, as a coal-fired furnace used as a heater, it mainly has technical problems such as low thermal utilization rate and environmental pollution.

[0003] For example, the Chinese patent with publication number CN201779847U proposes a high-temperature energy-saving and environmentally friendly heat transfer oil circulation furnace, which includes a coal-fired furnace, a heating liner arranged on the coal-fired furnace, and an oil barrel arranged on the outer periphery of the heating liner. A vortex tube is arranged in the heating liner, and the input end of the vortex tube is connected to the output end of the oil pump, and the output end of the vortex tube is connected to the inner cavity of the oil barrel. High thermal utilization rate. Since the utility model adopts a vortex tube for heating, the heat transfer oil forms a vortex flow, which makes the heating rapid and uniform, thereby improving the thermal efficiency. At the same time, an economizer is used to utilize the waste heat of smoke and dust, further improving the thermal efficiency. However, in this scheme, the inlet and outlet of the high-temperature oil furnace consume more energy during use. For this reason, we propose a new type of low-energy high-temperature oil furnace.
