Description
Technical field
The utility model relates to a kind of new polyester without oily waste silk reuse re-use device.
Background technology
At present, polyester industry development grows, and the consumption of polyester is also increasing day by day.Polyester fiber is widely used in industry-by-industry as a kind of macromolecular material, simultaneously, increasing of waste polyester quantity, if do not recycle waste polyester, not only can cause the wasting of resources, but also a large amount of pollutions can be brought to environment, also can produce unnecessary side effect to polyester industry, therefore, the great research topic be recycled in order to current polyester industrial develops of waste polyester.Although waste polyester can not produce direct pollution to environment, because it has extremely strong chemical inertness, be difficult to by air or microbial degradation, a large amount of spaces can be occupied, thus very large burden is caused to earth environment.
The processing method of existing waste silk has physical method and chemical method, and physical method mainly contains granulating method, friction material method, screw extrusion method etc., chemical method mainly contains EG depolymerization, and the device that existing EG depolymerization adopts is complicated, long flow path, invest high, be unfavorable for further genralrlization.
Utility model content
The utility model makes improvement for above-mentioned prior art Problems existing, and namely technical problem to be solved in the utility model is to provide a kind of structure is simple, organic efficiency is high new polyester without oily waste silk reuse re-use device.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of new polyester is without oily waste silk reuse re-use device, comprise EG preheating can, described EG preheating can is connected to alcoholysis groove through material conveying pipe, the material feeding conveyance conduit of described alcoholysis groove is provided with the nitrogen pressure valve of the carboxylate for producing after force feed alcoholysis, described alcoholysis groove is connected to buffering coppers through force feed pipeline, force feed pipeline between described alcoholysis groove and buffering coppers is provided with the carboxylate filter for filtering the impurity contained in carboxylate, described buffering coppers are connected to reaction kettle of the esterification through delivery pump by force feed pipeline.
Further, described carboxylate filter is made up of the first carboxylate filter and the second carboxylate filter, and described first carboxylate filter, the second carboxylate filter are attempted by force feed pipeline.
Further, condensing unit is equipped with above described alcoholysis groove, buffering coppers.
Further, described condensing unit is connected in series by fractionating column, condenser, condensed fluid collection tank and the first control valve group and forms.
Further, the material feeding conveyance conduit of described EG preheating can and material discharge pipeline are provided with some the second control valve groups for controlling material.
Compared with prior art, the utility model has following beneficial effect: the utility model utilizes the existing equipment of production of polyester factory to carry out polyester without oily waste silk reuse, and flow process is short, and the equipment that whole flow process is used is few; Small investment, high efficiency, and be easy to control, effectively alleviate the pollution to environment, increase factory's benefit.
