Abstract

The invention relates to a system for automatically regulating a temperature of an interlayer airflow inductive heated material pipe and belongs to a material pipe temperature regulating system and a material pipe temperature regulating method for regulating the temperature by ensuring gas in an interlayer of two pipes. An interlayer space is formed between a metal pipe and a non-metallic pipe; at least one group of inductance coils is wound on the outer surface of the non-metallic pipe; the pipe wall of the non-metallic pipe is provided with an air inlet and an air outlet; the air inlet is connected with an air inlet pipe and a blower; a temperature sensor is arranged in the metal pipe; the temperature sensor is connected with a main controller; the main controller is respectively connected with an air quantity controller and an electric conduction quantity controller; the air quantity controller is connected with the blower; and the electric conduction quantity controller is connected with the inductance coils. The material pipe temperature regulating system and the material pipe temperature regulating method have the advantages that the interlayer space has a heat preservation effect on the metal pipe and the utilization rate of electric energy is improved; people around the heated material pipe can be protected by the non-metallic pipe; and fluidity gas can be fed into theinterlayer space, or the temperature of the metal pipe is regulated by regulating a distance between each two adjacent inductance coils.

Description

technical field [0001] The invention belongs to the technical field of temperature regulation and control of material pipes, and in particular relates to a material pipe with materials flowing in the pipes, and a temperature adjustment system and method for the material pipes that use gas to flow in the interlayer of the two pipes for temperature regulation. Background technique [0002] Now the material tube that heats the fluid material in the material tube by heating the material tube is wrapped with multiple resistive heating blocks on the outside of the material tube, and uses the heat conduction of the resistive heating block to the material tube, and the material tube is heated. heating. To adjust or reduce the temperature of the material pipe is to use a blower to blow air on the resistance heating block, reduce the temperature of the resistance heating block, and indirectly reduce the temperature of the material pipe. Its disadvantages are: most of the heat of the ...
