Abstract

The invention discloses a preparation method of an activated carbon fiber compounded molecular sieve adsorption concentration runner. The method comprises the following steps: A, performing surface treatment on activated carbon fibers; b, carrying out pre-doping treatment on the treated activated carbon fiber and the treated fiber matrix, and carrying out corrugated forming; c, the corrugated composite paper and the flat fiber paper are subjected to stacking or winding forming through an adhesive, the stacking or winding mode is that one layer of composite paper and one layer of flat paper are stacked, and a honeycomb body module is obtained in the step; d, preparing an activated carbon fiber / molecular sieve composite adsorption material by a sol-gel method; and E, preparing to obtain the activated carbon fiber / molecular sieve composite adsorption concentration runner module. The activated carbon fiber / molecular sieve composite adsorption concentration rotating wheel module has the advantages of large adsorption capacity and strong adsorption capacity, in addition, the adsorption adaptability is wide, the adsorption capacity is large, the adsorption range is wide, and the problem that the adsorption concentration rotating wheel is poor in treatment effect on some waste gas components is solved.

Description

technical field [0001] The invention relates to a production technology of a molecular sieve adsorption and concentration runner, in particular to a preparation method of an activated carbon fiber composite molecular sieve adsorption and concentration runner, which belongs to the technical field of volatile organic compound VOCs adsorption treatment. Background technique [0002] There are many kinds of VOCs, complex components, and different properties. They are generally produced in industrial production, such as coating, printing, pharmaceutical, petroleum, chemical and other industries. VOCs will not only cause air pollution, but also seriously endanger human health. Therefore, at present, For industrial waste gas with large air volume and low concentration, the mainstream treatment method is incineration after adsorption and concentration, which has the characteristics of high efficiency and energy saving. [0003] Although the existing treatment methods are diverse, th...
