Abstract

The invention discloses a rod fin-type horizontal double-shaft stirring reboiler with propulsion blades. The rod fin-type horizontal double-shaft stirring reboiler with propulsion blades comprises a kettle body, a motor and a speed reducer connected to the motor. The top of the kettle body is provided respectively with a material inlet, a gas outlet and a manhole. Multiple material outlets are arranged at the bottom or a side wall of the kettle body. Two rotating shafts connected to an output shaft of the speed reducer are arranged in the kettle body. The two rotating shafts are respectively provided with multiple rod-type stirring fins at intervals. Each one of the rod-type stirring fins is provided with a propulsion blade. The rod-type stirring fins and the propulsion blades of the two rotating shafts are arranged crisscross. The rod fin-type horizontal double-shaft stirring reboiler with propulsion blades eliminates stirring blind angles and enhances stirring effects. Through the action between the rod-type stirring fins and the action between the rod-type stirring fins and the inner wall of the kettle body, materials bonded to the rod-type stirring fins and the inner wall of the kettle body can be scraped. Therefore, the rod fin-type horizontal double-shaft stirring reboiler with propulsion blades has strong self-cleaning effects and can avoid that materials are bonded to the interior of the kettle body.

Description

technical field

[0001] The invention relates to a reboiler, in particular to a rod-fin horizontal double-shaft stirring reboiler with propulsion blades having strong stirring, heat transfer and mass transfer effects. Background technique

[0002] Thermosiphon reboilers and Kettle kettle reboilers are often used in evaporation and distillation processes (ZL 200920088831.3, 2010; ZL 200810053594.7, 2010). The Kettle kettle reboiler is equipped with a gas outlet and a manhole on the top of the kettle body, and a material outlet at the bottom of the reboiler; the bottom of the reboiler of the thermosiphon reboiler is equipped with a material inlet and a gas outlet at the top. Part of the material is heated to the boiling state by the heat medium in the tube side in the evaporator, and then enters the distillation tower from the gas outlet. For high-boiling point materials, especially heavy tar or phenol tar, coal tar, polymers and other similar materials with high viscosity, hi...
