Problems solved by technology

The one-time use of the power plant brings a great burden on the economy, and after the filter bag is used in a thermal power plant, a lot of heavy metals and harmful elements are attached to the filter bag. After deep burial, it cannot solve its environmental protection problems. More damage to deeper soil

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] combine figure 1 , an embodiment of the present invention. A PPS recovery system in waste dust removal bags, characterized in that it includes a cleaning device for removing dust from the dust removal bags, a drying device for drying the cleaned dust removal bags, a segmentation device for cutting the dried dust removal bags, A layering device for splitting the divided dust bag into layers and an opening device for opening and restoring the split dust bag into flocculent PPS fibers. In this embodiment, a vibrator is fixed inside the cleaning device, and the vibrator is in contact with the cleaning liquid in the cleaning device and provides vibration to the cleaning liquid. In this embodiment, the cleaning device, drying device, dividing device, layering device and opening device are fixed together in sequence, and the PPS filter bag is processed through the ab...

The system comprises a cleaning device, a drying device, a cutting device, a layering device and an opening device, wherein the cleaning device is used for cleaning the dust removal bag, the drying device is used for drying the cleaned dust removal bag, the cutting device is used for cutting the dried dust removal bag, the layering device is used for layering and splitting the cut dust removal bag, and the opening device is used for opening the split dust removal bag into flocculent PPS fiber.

Description

technical field [0001] The invention relates to the field of dust removal and recovery technical equipment, in particular to a method and system for recovering PPS in waste dust removal bags. Background technique [0002] At present in my country, PPS (polyphenylene sulfide) filter bags are widely used in air dust removal and filtration in thermal power plants. However, these PPS filter bags generally have no effective recycling methods after use, and can only be buried deeply. Since most of the PPS fibers are imported, domestic PPS fibers have less output due to technological problems, and most of the PPS filter bags are imported. The one-time use of the power plant brings a great burden to the economy, and after the filter bag is used in a thermal power plant, a lot of heavy metals and harmful elements are attached to the filter bag. After deep burial, it cannot solve its environmental protection problems. more damage to the deeper soil. Contents of the invention [0...
