Said equipment includes low-temperature system oil-returning pipe and high-temperature system oil-supplying pipe, between them an oil-supplying pipe is connected; between low-temperature system oil-returning pipe and high-temperature system oil-returning pipe are connected a low-temperature oil-discharging pipe and a temperature-regulating device.

Description

Technical field: [0001] The invention relates to a method and a device for supplying heat-conducting oil at different temperatures by using a heat-conducting oil heating furnace with the same parameters in an electrolytic aluminum anode production system, and belongs to the technical field of heat-conducting oil supply for thermal equipment used in the electrolytic aluminum anode production system. Background technique: [0002] At present, in the aluminum anode production system, heat transfer oil is used as a high-temperature heat carrier to exchange heat with heat-consuming equipment in the production process of paste making and asphalt melting, and plays a heating role. Due to the needs of process production, the heat consumption of each heat-using equipment is different, and the temperature requirements for heat-conducting oil are also different. Therefore, the heat-conducting oil heating station supplies heat-conducting oil of different temperatures according to the nee...

Problems solved by technology

[0003] There are two methods used in the past: one is to use a heat transfer oil supply temperature, although the heat conduction oil supply system is relatively simple, but because it is a kind of oil temperature, it cannot well meet the temperature requirements of different production links, and the product Performance has a certain impact

The second is to use different types of heat-conducting oil furnaces to supply different temperatures of heat-conducting oil. Although it meets the different temperature requirements of different heat-using equipment and ensures product quality, due to the different heat consumption of heat-using equipment at various temperatures, various Heat transfer oil furnaces with different temperatures supply different heat, that is, the specifications of the heat transfer oil furnace in a heat transfer oil heating station are different. The higher the oil supply temperature, the more furnace types, which increases investment and brings inconvenience to operation and management. It also makes it impossible for each heat conduction oil furnace to serve as backup for each other.
