Description

Technical Field

[0001] The utility model relates to the technical field of epoxy resin production, in particular to a condenser for epoxy resin production. Background Art

[0002] Epoxy resin is a high molecular polymer, which refers to a class of polymers containing two or more epoxy groups in the molecule. It is the condensation product of epichlorohydrin and bisphenol A or polyol.

[0003] A large amount of toluene is used in the production of epoxy resin. In order to reduce production costs, the residual toluene in the waste liquid after production is recovered. At present, toluene is recovered by distillation. During distillation, a condenser is needed to condense the toluene vapor into toluene liquid for recovery. However, the existing condensers all use a pipe to pass the toluene vapor through a water flow for condensation. The single pipe to guide the toluene vapor will concentrate the heat in the toluene vapor, which is not conducive to rapid heat dissipation. Moreover, the condensation speed is slow only by water flow. Therefore, in view of the above status quo, it is urgent to develop a condenser for epoxy resin production that first diverts the toluene vapor to reduce the concentration of heat, and then cools and condenses the toluene vapor by air cooling and cold water at the same time, so as to overcome the shortcomings in current practical applications and meet current needs.
