Description

Recovery equipment for preparing bisphenol F epoxy resin

Technical Field

The invention relates to a technology for recovering bisphenol F epoxy resin preparation waste, in particular to a recovery device for preparing bisphenol F epoxy resin.

Background

Bisphenol F epoxy resin, also called bisphenol F diglycidyl ether, BPF for short, is a novel epoxy resin developed for reducing the viscosity of bisphenol A epoxy resin and having the same performance, and is characterized by small viscosity which is less than 1/3 of the viscosity of bisphenol A epoxy resin and good impregnation property to fibers. The cured product of the resin composition has almost the same properties as bisphenol A epoxy resin, but has slightly low heat resistance and slightly excellent corrosion resistance. The liquid bisphenol F type epoxy resin can be used for solvent-free coatings, adhesives, cast plastics, glass fiber reinforced plastics, carbon fiber composite materials and the like. The production of bisphenol F epoxy resin is mainly carried out in two steps, wherein in the first step, phenol and 37% formaldehyde aqueous solution react to generate bisphenol F under the condition that 35% hydrochloric acid is used as a catalyst; and secondly, carrying out polycondensation reaction on the bisphenol F and epoxy chloropropane in the presence of sodium hydroxide to obtain the bisphenol F type epoxy resin.

At present, the existing recovery equipment for preparing bisphenol F epoxy resin is usually used for simply treating waste liquid by a sedimentation method, the solution after simple treatment cannot reach the discharge standard, and the settled solid particles also contain more solution and still need secondary separation, so that the use effect is poor, the production cost is increased, and the environment is greatly damaged;

the utility model with application number CN202021283635.4 discloses a waste recovery device for epoxy resin production, in the technical scheme, waste liquid in production is filtered by two groups of obliquely arranged filter plates, liquid obtained after filtration is pumped to a sedimentation tank through a water pump for sedimentation, and finally the liquid after sedimentation is recovered; firstly, in the technical scheme, although the waste liquid is filtered, the filtered waste liquid still adopts a sedimentation tank sedimentation treatment mode, the actual treatment effect on the waste liquid is not obvious, and the sedimentation tank is still a simple collection tank, so that the sedimentation tank cannot be conveniently reformed if the waste liquid treatment means is changed due to the improvement of the production process or the change of the environmental temperature; secondly, this scheme is when filtering, and the filter is for using continuously, in the use, the filter effect can descend gradually, consequently in this period that the effect descends, have partly solution because the filter blocks up and go in the collection device that flows into solid waste, after filter effect descends to certain extent, just can clear up the filter through the manual work, and the manual work is also wasted time and energy to the cleanness of filter to unrestrained waste liquid also can cause the pollution to the environment when the filter takes out.

In view of the above technical problem, the present application proposes a solution.
