Filament winding alternation-type filtering device for textile waste gas

Abstract

The invention discloses a filament winding alternation-type filtering device for textile waste gas, belongs to the field of textile waste gas filtering devices, and innovatively adopts a mode of winding a tough filament for taking-up. The tough filament drives textile fibers mingled between filtering soft brushes on the surface of a filter cartridge, and the textile fibers are tightly wound by thetough filament in a tough filament winding process. Meanwhile, in the winding process of the tough filament, the other tough filament moves to the position where the tough filament is located along with synchronous rotation to replace the tough filament to receive subsequent textile fibers, and then the wound tough filament is gradually unfolded in cleaning water and cover the initial position ofthe other tough filament while the textile fibers in a winding clamp are cleaned, so that the cleaning process of the textile fibers on the surface of the filter cartridge is achieved. Meanwhile, thepositions of the pair of the tough filaments are exchanged and alternated so as to guarantee that waste gas purification is not affected by the cleaning process, barrier-free continuous operation isachieved, and smooth operation of the next cleaning process is also guaranteed.

Description

technical field [0001] The invention relates to the field of textile waste gas filtering devices, and more specifically, relates to a winding and alternate filtering device for textile waste gas. Background technique [0002] Exhaust gas from the textile printing and dyeing industry mainly comes from two aspects: one is the spinning process of chemical fibers, and the other is the pre-treatment and functional finishing processes of textiles. Generally, the high-temperature exhaust gas discharged contains not only dust particles, but also a large amount of fiber pollutants. (such as short staples, cotton wool, etc.) and dust, and some processes will also have emissions such as additives and oil wax. If they are not treated and discharged directly, they will not only endanger human health, but also cause air pollution. [0003] Because textile waste gas contains a large amount of fiber pollutants (such as short velvet, cotton wool, etc.), these large particles of impurities, i...

[0002] Exhaust gas from the textile printing and dyeing industry mainly comes from two aspects: one is the spinning process of chemical fibers, and the other is the pre-treatment and functional finishing processes of textiles. Generally, the high-temperature exhaust gas discharged contains not only dust particles, but also a large amount of fiber pollutants. (such as short staples, cotton wool, etc.) and dust, and some processes will also have emissions such as additives and oil wax. If they are not treated and discharged directly, they will not only endanger human health, but also cause air pollution.

[0003] Because textile waste gas contains a large amount of fiber pollutants (such as short velvet, cotton wool, etc.), these large particle impurities, it is necessary to filter the waste gas to remove these fiber pollutants in the process of textile waste gas treatment, but fiber pollution During the treatment process, it is very easy to cause the blockage of the filter equipment, making it difficult for the entire filtration process to be continuously and efficiently carried out, and the efficiency is low
