Description

Technical Field

[0001] This utility model relates to the field of heating and energy-saving devices, and in particular to an intelligent tungsten alloy heating and energy-saving device for refining and distillation towers. Background Technology

[0002] Distillation columns are crucial equipment in petroleum refining and chemical production processes, primarily used to separate different components from mixtures. The main function of a distillation column is to separate complex multi-component mixtures into single or relatively pure components. By precisely controlling operating parameters such as temperature, pressure, and reflux ratio, distillation columns can produce products that meet stringent quality standards. Traditionally, materials in refining distillation columns are heated by exchanging heat with steam or heat transfer oil in a reboiler. This process requires a gas-fired boiler to heat water or heat transfer oil to 120 kg of high-temperature, 600°C, high-pressure steam. The 600°C heat transfer oil or 120 kg of high-pressure steam is then piped to the reboiler at the production site for heat exchange. The gas-fired boiler emits large amounts of nitrogen oxides, polluting the air. Furthermore, the boiler requires natural gas for combustion to generate heat, and natural gas combustion is a hazardous material requiring real-time monitoring, posing a potential safety and explosion hazard to the production process.

[0003] When using refining and chemical distillation towers, there is a problem of low heating efficiency due to the traditional method of heating materials through reboilers. In view of this, we provide an intelligent tungsten alloy heating and energy-saving device for refining and chemical distillation towers. Utility Model Content

[0006] Furthermore, the baffle plate divides the tower body into several heating chambers, and the connection between the baffle plate and the tower body is an arc-shaped structure.

[0007] Furthermore, the upper surface of the baffle plate is provided with several through holes, and several No. 1 heaters are fixedly installed inside the baffle plate.

[0010] Furthermore, the feeding section includes a feeding pipe, one end of which is fixedly fitted with a heating pipe, and the other end of which is fixedly fitted with a connecting pipe, which connects to the heating chamber.

[0011] Furthermore, the heating tube has a spiral structure, and the inner wall of the connecting tube has a tapered structure with a decreasing radius from the heating tube to the heating cavity.

The first heater 111 of each layer of the baffle plate 11 is independently temperature controlled. The through holes 112 promote gas-liquid contact. After the heavy components condense, they flow back along the surface of the baffle plate 11, while the light components continue to rise.

The raw material enters the spiral heating tube 22 through the feed tube 21. The tungsten alloy electric heating element in the heating tube 22 is energized to heat the raw material to the preset temperature. The spiral structure extends the flow path to ensure sufficient heating. The spiral heating tube 22 increases the heat transfer area to avoid local overheating. The conical structure of the connecting tube 23 pressurizes the material and increases the flow rate when entering the tower body 1 to avoid coking. In practical use, the raw material enters the spiral heating tube 22 through the feed pipe 21. The tungsten alloy electric heating element inside the heating tube 22 is energized to heat the raw material to the preset temperature. The spiral structure extends the flow path to ensure sufficient heating. The spiral heating tube 22 increases the heat transfer area to avoid local overheating. The conical structure of the connecting pipe 23 pressurizes the material and increases the flow rate when entering the tower body 1 to avoid coking. The high-temperature material is evenly distributed to the bottom of the tower body 1 through the discharge hole 132. The second heater 131 maintains a constant temperature at the bottom to ensure rapid vaporization of the material. The vaporized material rises to the heating chambers 12 of each layer. The first heater 111 of each baffle plate 11 has independent temperature control. The through hole 112 promotes gas-liquid contact.
