Background technique

A lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. The sulfuric acid production process for lead-acid batteries is mainly composed of five parts, including the production of sulfur dioxide gas, the purification of furnace gas, the conversion of sulfur dioxide gas, the absorption of sulfur trioxide gas and the treatment of tail gas. The invention aims at purifying the furnace gas produced by burning pyrite ore to produce sulfur dioxide.

When the furnace gas prepared with sulfuric acid for lead-acid batteries enters the purification device, the furnace gas contains mineral dust. The accumulation of mineral dust not only blocks the pipeline equipment, but also the iron oxide in it can form iron sulfate with the acid mist, covering the surface of the sulfur dioxide catalyst. The surface not only reduces the activity of the catalyst, but also increases the resistance of the bed. At present, the furnace gas treatment in the preparation of sulfuric acid for lead-acid batteries is carried out by dry method or wet method. At present, wet method is generally used for purification. The existing wet method directly injects the furnace gas into the dust reduction chamber, and removes the mineral dust in the furnace gas by water leaching , the water is directly in contact with the furnace gas to separate the mineral dust carried in the furnace gas. This requires high water showering, and the control of water showering is not in place, so that the mineral dust carried in the furnace gas cannot be separated, resulting in furnace gas Directly discharged, producing a large amount of mineral dust.

the spun water will drop through the inside of dust fall room (1), will carry the mineral dust that carries in the stove gas, the water of whereabouts will pass through the top of filter (16), the fixed impurity that carries in to the water through filter (16) filters, drive rotatory piece (15) rotatory simultaneously in transmission post (7), through the rectangular channel of scraper blade (17) one end when rotatory piece (15), remove right-hand member in drive scraper blade (17), scraper blade (17) extrude two second springs (20) respectively, the bottom of scraper blade (17) will contact with the top of filter (16), clear up the solid particle at filter (16) top, scrape the right-hand member to collection box (5), when rotatory piece (15) are rotatory to the right-hand member, the bottom of the high rotatory piece (15) in top of scraper blade (17), two second springs (20) will reset this moment and drive scraper blade (17) reset, rotatory piece (15) continuous rotation, drive scraper blade (17) left and right-hand member is removed, the top of filter (16) is cleared up through drain (25) at the drain, drain (11) is discharged through the drain.
