Description
Technical Field
The invention belongs to the technical field of heating equipment, and particularly relates to a heating/vaporizing device comprising a built-in coil.
Background
In the laboratory, the flow of the experimental feedstock is small and there is generally no steam as a source of steady heat. When the experimental raw materials need to be heated/vaporized continuously, the heating/vaporizing method commonly used by large-scale chemical devices is difficult to be directly applied due to small flow, and a proper heating/vaporizing device is difficult to find.
Common continuous heating/vaporization methods include:
(1) electric heating jacket heating/vaporization method: the flask filled with the experimental raw materials is arranged in the electric heating sleeve, and an electric heating program is started for heating. The method has controllable heating and simple operation. However, the raw materials are usually added at one time and used for the batch distillation of liquid raw materials, so that the continuous heating is difficult to realize.
(2) Electric heating rod heating/vaporization method: an electric heating rod provided with an electric heating element is extended into the heating/vaporizing device to heat the experimental raw materials and heat or vaporize the experimental raw materials. The method has the advantages of rapid temperature rise and low equipment material cost. Because the temperature of the electric heating rod is high and the temperature rise is fast, local overheating of a contact part area of the electric heating rod can be caused, and raw materials are coked or decomposed. The temperature rise and the temperature drop are fast, and the temperature rise and the temperature drop are difficult to control.
(3) Electric heating/vaporizing method for outer wall of hollow tube: the electric heating belt is wound on the outer wall of the hollow pipe, the electric heating belt heats the outer wall of the hollow pipe, and the outer wall transfers heat to the raw materials in the hollow pipe to heat or vaporize the raw materials. The method has the advantages of simple equipment structure, low equipment manufacturing difficulty and low material cost. However, the pipe wall is directly heated, and the temperature difference exists in the radial direction of the pipe, so that hot spots can be formed on the local inner wall of the pipe, the experimental raw materials are coked or decomposed, and the central temperature of the pipe is low, so that the raw materials are not heated completely.
(4) Straight tube outside jacket oil bath heating/vaporization method: the hollow pipe is externally provided with a jacket, heat conduction oil is filled in the jacket, a heat conduction oil circulating heating oil bath system is externally arranged, the heat conduction oil is heated through the oil bath system, the heat conduction oil transfers heat to the outer wall of the hollow pipe and then transfers heat to the raw material, and the raw material is heated or vaporized. The method has the advantages of high heating precision, uniform heating, no local hot spot and high safety. But the heat transfer coefficient of the pure pipe wall is small, the heat exchange area per unit length is small, and the method is not suitable for occasions with limited length.
(5) Tube oil bath heating/vaporization method: the heating/vaporizer is of a tubular structure, a tube pass is taken by general raw materials, a shell pass is taken by heat conduction oil, a heat conduction oil heating circulating oil bath system is arranged outside, the heat conduction oil is heated by the oil bath system, the heat conduction oil transfers heat to the heat exchange tubes, and then the heat is transferred to the raw materials, so that the raw materials are heated or vaporized. The method has the advantages of large heat exchange area, strong heating capacity, uniform heating, no local hot spot and high safety. However, the internal parts are more, the sealing points are arranged in the internal parts, leakage is easy to occur, the structure is complex, the manufacturing difficulty is higher, the cost is higher, and the maintenance is difficult.
