Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a condensing device for a reaction kettle. Background Art

[0002] Reflux condenser is a type of condenser. The most common one is reflux glass condenser. Reflux condenser is often used to connect to reactor, condense the gas produced in the reactor, discharge the condensed liquid back into the reactor, and discharge the condensed gas. Ordinary reflux condenser adopts spiral piping in the container, and introduces refrigerant in the spiral piping. The refrigerant is mostly water. The spiral piping contacts the gas to cool down and condense the liquid. In order to increase the contact area with the gas, some condensers will make innovative designs in the arrangement of spiral piping. For example, the spiral piping adopts multiple pipes to cross-set, or multiple pipes are nested in multiple layers with different spiral diameters. However, the spiral piping is often set in the center of the container near the axis. After the gas enters the container, it contacts the spiral piping and is diverted to both sides. A considerable part of the gas will flow through the gap between the threaded pipe and the side wall of the container and leave the container, resulting in reduced condensation efficiency and insufficient condensation.

[0003] Therefore, the problem that the inventor wants to solve is to design a device with a flow channel set in the side wall to assist condensation and improve the condensation effect. Utility Model Content
