Embodiment Construction

[0011] Such as figure 1 As shown, a distillation condensation reflux device, the reflux condenser includes a distillation port (10), a distillation tube (8), a condenser (1), a receiver (6), a valve on the receiver (5), a receiver It is composed of a lower valve (7) and a return pipe (12); a serpentine condenser pipe (3) is arranged inside the condenser, the lower end of the condenser pipe is a condensed water inlet (4), and the upper end is a condensed water outlet (2). The distillation pipe (8) is a right-angled elbow connected at the lower end to the distillation port, and at the upper end to the lower end of the condenser. A distillation pipe valve (9) is arranged in the middle of the distillation pipe, and a demister (13) is installed behind the valve through a flange connection. The demister is used to remove the flushing foam entering the condenser during the distillation process. The return pipe (12) is a straight pipe, the lower end of which is connected to the disti...

Abstract

The invention discloses a distillation condensing refluxing device. A refluxing condenser comprises a distillation port (10), a distillation pipe (8), a condenser (1), a receiver (6), a receiver upper valve (5), a receiver lower valve (7) and a refluxing pipe (12). The condenser is internally provided with a snakelike condensing pipe (3), the lower end of the condensing pipe is a condensate water inlet (4) and the upper end is a condensate water outlet (2). The distillation pipe (8) is a right-angled elbow pipe, the lower end of the distillation pipe is connected with the distillation port and the upper end is connected with the lower end of the condenser, a distillation pipe valve (9) is arranged at the middle of the distillation pipe, and a demister (13) is arranged behind the valve. The refluxing pipe (12) is a straight pipe, the lower end of the refluxing pipe (12) is connected with the distillation pipe below the distillation pipe valve (9), and the upper end is connected with the straight pipe at the lower end of the condenser and is located below the distillation elbow pipe and above the receiver upper valve (5). The distillation condensing refluxing device has the advantages that the structure is simple, the distillation gas does not affect the refluxing of refluxing liquid, and the practicability is high.

Description

technical field [0001] The invention designs a distillation condensation reflux device, especially a distillation condensation reflux device for large flow condensation reflux operation in the field of organic chemical industry. Background technique [0002] The reflux condenser is a commonly used equipment in the production process of organic chemical industry. The existing reflux condenser includes a distillation tube, a condenser, and a receiver. The organic vapor enters the condenser through the distillation tube, and the condensed organic matter enters the receiver, or the receiver is closed. The valve returns to the reactor through the distillation tube. When the amount of organic vapor increases, the rising organic vapor will easily hinder the return of the reflux condensate, resulting in air resistance and affecting the production operation. Contents of the invention [0003] The invention provides a reflux condenser with simple structure, strong practicability and...
