Description

Heating pipeline structure capable of quickly raising temperature Technical Field The utility model provides a heating pipeline structure capable of quickly heating, and belongs to the technical field of pipeline electric heaters. Background The pipeline electric heater is a structure which consumes electric energy and converts the electric energy into heat energy, namely a heating pipeline, so as to heat materials to be heated. In operation, a low-temperature fluid medium enters an input port of the electric heating container under the pressure action through a pipeline, and a path designed by utilizing the thermodynamic principle of the fluid is taken away along the specific heat exchange flow channel in the electric heating container, so that the temperature of the heated medium is quickly increased, and a high-temperature medium required by a process is obtained at an outlet of the electric heater. When the heating element is overtemperature, the independent overheat protection device of the heating element immediately cuts off the heating power supply, thereby avoiding coking, deterioration and carbonization caused by overtemperature of the heating material, and effectively prolonging the service life of the electric heater. The existing pipeline electric heater basically can meet the normal use requirement, but still has the defect that the shell of the pipeline electric heater generally comprises an inner shell layer, an outer shell layer and a heat preservation cotton layer arranged between the inner shell layer and the outer shell layer and is used for heat preservation, and although the heat preservation can be well carried out, when a heating element heats a medium, due to the heat transfer performance, the situation that a small amount of heat is lost outwards from a heat exchange flow channel sequentially through the inner shell layer, the heat preservation cotton layer and the outer shell is unavoidable, the heat is lost, the lost heat is difficult to be reused, and the heat utilization rate is to be improved. Based on the above, the utility model provides a heating pipeline structure capable of quickly heating.
