Description

technical field [0001] The invention relates to the technical field of heat conduction oil heating, in particular to a heat conduction oil heating system. Background technique [0002] Traditional heat transfer oil fuel heaters use coal, heavy oil, light oil, combustible gas or other combustible materials as fuel, use heat transfer oil as the heat carrier, and use circulating oil pumps to force liquid phase circulation to transfer heat energy to heat-consuming equipment and then return Reheating once-through special industrial furnace. However, the temperature of the heat transfer fluid in the furnace is high, and most of them are flammable and explosive. Once leakage occurs during operation, it will cause fire, explosion and other accidents, and even cause casualties and property losses. The heat conduction oil electric heater is a new type, safe, high-efficiency and energy-saving, low-pressure (atmospheric or lower pressure) and special industrial furnace that can provide...

Problems solved by technology

The heating system of this heating method has the characteristics of simple appearance, compact structure, and convenient operation. However, during the production process, the electric heating tube directly contacts the heat transfer oil for heating. The maximum allowable working temperature is generally around 300 degrees Celsius. Due to the carbonization and deterioration of the heat transfer oil due to local long-term high temperature, the heat transfer efficiency of the heat transfer oil continues to decline. It is very difficult to clean the inner wall of the heating tank

In addition, the existing heating tank or heating ax is usually designed in the shape of a cylindrical tank. This shape of the heating tank is very easy to cause heat dispersion, and the heat conduction oil is heated unevenly, resulting in uneven and uneven temperature output to the heating equipment. Stable; the temperature of the heat transfer oil in the heating tank does not accumulate, the heat is easily lost, the heat storage effect is poor, and the energy consumption is large

In order to improve energy efficiency, the heat transfer oil heating system currently on the market adopts the most method of changing the shape or structure of the electric heater, such as designing the electric heater in a spiral shape to increase its contact surface with the heat transfer oil, but this change is also at the same time Increased power consumption
