The accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms the part of specification, for explaining the present invention, is not construed as limiting the invention together with embodiments of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the equipment used of the mercerization of application liquid caustic soda hyperfiltration process in the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of mercerizing equipment with the real time filtering device, comprise and roll alkali groove 1, roll 2, spray thrower 3 and rinsing bowl 4, described roll 2 is arranged on and rolls between alkali groove 1 and rinsing bowl 4, described spray thrower 3 is arranged on the top of rinsing bowl 4, described front end top of rolling alkali groove 1 is provided with into material roller 5, and top, the rear end of described rinsing bowl 4 is provided with discharge roller 6.
The described alkali groove 1 that rolls is connected with the real time filtering device.Described real time filtering device comprises the first coarse filtration device 11 and the first filtering device using hollow fiber ultrafiltration membrane 12.The described alkali groove 1 that rolls is connected with the first filtering device using hollow fiber ultrafiltration membrane 12 with described the first coarse filtration device 11 respectively, and described the first coarse filtration device 11 and the first filtering device using hollow fiber ultrafiltration membrane 12 interconnect.
Described rinsing bowl 4 is connected with salkali waste and reclaims filter.Described salkali waste reclaims filter and comprises the second coarse filtration device 41 and the second filtering device using hollow fiber ultrafiltration membrane 42.Described rinsing bowl 4 is connected with described the second coarse filtration device 41, and described the second coarse filtration device 41 and the second filtering device using hollow fiber ultrafiltration membrane 42 interconnect, and described the second filtering device using hollow fiber ultrafiltration membrane 42 is connected with recycle of alkali liquor pond 43.
What described the first and second filtering device using hollow fiber ultrafiltration membranes adopted is the inner pressed hollow fiber ultrafiltration membrane, and material is polyethersulfone resin.
Specifically being implemented as follows of the mercerization of the application liquid caustic soda hyperfiltration process carried out based on the said equipment:
The alkali lye that the first coarse filtration device will roll in the alkali groove tentatively filters, alkali lye after tentatively filtering is sent into to the first filtering device using hollow fiber ultrafiltration membrane, after the first filtering device using hollow fiber ultrafiltration membrane carries out the essence filtration, alkali lye after the essence filtration is sent back to and rolls in the alkali groove, the cleannes of alkali lye in the alkali groove are rolled in assurance, and due to essence filter limited in one's ability, the first filtering device using hollow fiber ultrafiltration membrane can return to the first coarse filtration device by not carrying out the alkali lye that essence filters, and repeats filter process.During fabric process spray thrower below, the alkali lye adhered to can be washed in rinsing bowl, alkali lye in rinsing bowl is sent to the second coarse filtration device, after tentatively filtering, alkali lye after tentatively filtering is sent into to the second filtering device using hollow fiber ultrafiltration membrane and carry out the essence filtration, alkali lye after again essence being filtered is sent to the recycle of alkali liquor pond, and due to essence filter limited in one's ability, the second filtering device using hollow fiber ultrafiltration membrane can return to the second coarse filtration device by the alkali lye that does not carry out the essence filtration, repeats filter process.Be sent to the alkali lye in the recycle of alkali liquor pond, can carry out concentration and evaporation, recycle after evaporation in the mercerising process, after also can allocating concentration of lye, for pre-treatment, to reduce the consumption of commercially available alkali.
