Description

Technical Field

[0001] The utility model relates to the technical field of reboilers, in particular to a low-energy-consumption rapid-circulation reboiler. Background Art

[0002] Reboiler is an important industrial equipment used to heat and evaporate liquids. In the fields of petroleum, chemical industry, pharmaceutical industry, etc., reboiler is widely used in heating, evaporation, distillation and other processes. Traditional reboilers have problems such as high energy consumption and slow circulation speed, which not only increases production costs but also affects production efficiency. Reboiler is often used in conjunction with distillation tower. It is a special heat exchanger that can exchange heat and has gasification space. In industrial production, the main function of heat exchange equipment is to transfer heat from a fluid with a higher temperature to a fluid with a lower temperature. It is an indicator of the fluid temperature reaching the process flow to meet the needs of the industrial process. In the processing of coal tar, the heat source of the reboiler is heat transfer oil, and the medium to be heated is high-viscosity coal tar. The forced circulation reboiler is currently used, which consists of a shell with a gas-liquid separation space and a removable U-shaped tube bundle. There is an overflow weir at the end of the tube bundle to ensure that the tube bundle can be effectively immersed in the liquid. However, since the liquid will not flow after entering, many liquids are heated unevenly, so that the entire reboiler cannot heat up quickly.

[0003] Existing technical problems: A filter is added inside the existing reboiler to block impurities. Too many impurities will cause clogging of the filter, so the material cannot enter the reboiler, affecting the working efficiency of the reboiler. Utility Model Content

[0010] Preferably, a sewage box is provided at the outlet of the sewage outlet, and one end of the sewage box is movably connected to the surface of the support seat.

[0011] Preferably, the output end of the rotating motor is electrically connected to one end of the telescopic driving rod, and the two ends of the heat-insulating outer shell close to the support seat are movably connected with fixing screws.

[0012] Beneficial Effects

[0013] In the utility model, a soft brush is adopted, and the retractable driving rod is controlled to rotate by a rotating motor, and the retractable driving rod drives the soft brush to clean the impurities on the surface of the filter plate, thereby realizing that a filter screen is added inside the reboiler to block impurities, and excessive impurities will not cause clogging of the filter screen, so that materials can enter the reboiler without affecting the working efficiency of the reboiler.

[0014] In the utility model, an exhaust cover is adopted, and the exhaust port is blocked by the exhaust cover through a retractable support frame.
