Description
Technical field
The present invention relates to exhaust-gas treatment field, particularly relate to a kind of polyamide granulation emission-control equipment.
Background technology
Polyamide, is called for short PA, for main chain having the condensate of amido link.Can be obtained by diamine and binary acid polycondensation, lactams ring-opening polymerisation.Multiple polyamide is obtained because binary acid used is different with the kind of diamine.High-molecular polyamide resin and low molecule pa resin is roughly divided into by the size of relative molecular weight.
High-molecular polyamide resin, namely the nylon known of people or polyamide fibre, be made up of straight-chain aliphatic binary acid and diamine, mainly for the preparation of synthetic fibers and engineering plastics, the class polyamide that R and D technics comparing is complete.Low molecule pa resin obtains, also known as dimer acid polyamide resin after carrying out polycondensation reaction by dimeric dibasic acid and diamine or polyamine.Two large classes can be divided into: non-reacted or neutral polyamide and reactive polyamide by its character.Neutral polyamide synthesizes, for the production of ink, heat sealing adhesive and coating primarily of dimeric dibasic acid and ethylenediamine.
Polyamide can volatilize a large amount of organic exhaust gas when granulation, as processed not in time, and the environment that can pollute.
At present, the waste gas volatilized when processing polyamide granulation removes mainly through spray process.This kind of method is simple to operate, but can only remove part aqueous waste gas in waste gas, and the removal effect for water-fast odorant is bad, and absorptivity has much room for improvement.Utilize bioanalysis the odorant pollutant decomposition and inversion contained in waste gas can be become less or even harmless material.Simple biomembrane process waste gas, need to hang a large amount of biomembranes, and reaction condition is wayward.
