The pulverizer 10 is connected to a driving motor, and the first feeding bin 8 is of a closed structure. When the device is running, the waste filter bags in the first feeding bin 8 are conveyed to the pulverizer 10 along the first conveying belt 9 for crushing.

[0027] The burning device comprises a second feeding bin 14 connected to the outlet of the pulverizer 10, the outlet of the second feeding bin 14 is connected to the inlet of a smelting furnace 1, the smoke outlet of the smelting furnace 1 is connected to a bag-type dust collector 6, and the smoke outlet of the bag-type dust collector 6 is connected to an acid production system (not shown in the drawings). After the crushed filter bags enter the smelting furnace 1, high-temperature burning is carried out, the flue gas generated during the burning process enters the bag-type dust collector 6, and after filtration and dust removal, it is conveyed to the acid production system, which can be used for producing sulfuric acid.

[0028] A weighing part (not shown in the drawings) for detecting whether the first conveying belt 9 normally transports waste filter bags is arranged on the first conveying belt 9. Since the filter bags may be knotted or blocked when stored in the first feeding bin 8, the conveying condition of the waste filter bags can be directly reflected through the weighing part, and it can also be detected whether foreign matter or ash blocks are present on the first conveying belt 9 at this time. Once an abnormality is found, a signal can be sent in time to stop and maintain. An inductive probe (not shown in the drawings) for detecting whether the pulverizer 10 normally discharges is arranged at the outlet of the pulverizer 10. The inductive probe is an infrared inductive probe, which can determine whether the discharge of the pulverizer 10 is normal.

[0029] The crushing device further comprises a negative pressure dust collector 13, a first air extraction pipeline 16 is arranged between the negative pressure dust collector 13 and the first feeding bin 8, a second air extraction pipeline 17 is arranged between the negative pressure dust collector 13 and the first conveying belt 9, and a third air extraction pipeline 18 is arranged between the inlet of the pulverizer 10 and the negative pressure dust collector 13. The negative pressure dust collector 13 can be connected to the three air extraction pipelines through a four-way joint, and the negative pressure dust collector 13 can timely adsorb and accommodate the dust generated in the conveying process of the waste filter bag, and purify the production environment.

The collected smoke dust is sent to the material preparation for re-mining treatment.

[0033] The electric dust collector 4 has a second recovery part for collecting dust in the incineration flue gas. The electric dust collector 4 further collects the dust in the flue gas by the principle of same polarity repulsion and different polarity attraction. The product collected here is white smoke dust, which can be sold outside to reduce the operating cost of the equipment.

[0034] The quenching tower 5 has a third recovery part for collecting diarsenic trioxide in the incineration flue gas.

[0036] The products collected by the quenching tower 5 and the bag-type dust collector 6 are diarsenic trioxide, which is a dangerous waste and can be sold outside to reduce the operating cost of the equipment.

[0037] The device further comprises a fan 7 for generating negative pressure in the negative pressure dust collector 13 and guiding the incineration flue gas discharged from the bag-type dust collector 6 into an acid production system. The fan 7 is connected to the negative pressure dust collector 13 and the bag-type dust collector 6 through a three-way joint.

[0038] The waste filter bag is crushed by the crushing device, the crushed filter bag is combusted by the incineration device, the flue gas formed by combustion can be used for producing sulfuric acid after layer-by-layer filtration, and the impurities in the flue gas can be recycled and treated, so that the operation cost of the equipment is reduced.
