Description
Technical field
The utility model relates to the catalyst of gas washing in SA production, also relates to screening operation, in particular to the screening plant of sulfuric acid catalyst.
Background technology
As everyone knows, in the sulphuric acid process, the SO in the unstripped gas
2Be converted into SO
3Need to use catalyst, catalyst commonly used is a vanadium catalyst, is vanadium catalyst in the factory again.Active material in the vanadium catalyst is V
2O
5In the production process, vanadium catalyst can be because air-flow and high temperature and efflorescence gradually.The vanadium catalyst of efflorescence can cause the obstruction of converter, increases SR, and conversion ratio is reduced.Therefore, sulfuric acid enterprise according to the mensuration of SR and conversion ratio, needs the cleaning converter after the driving certain hour, sift out the catalyst of efflorescence, replenishes the catalyst amount.Yet artificial driving is adopted in the inner catalyst screening of converter usually, and manually sieve on handling to ground, backfill again after screening is good.The catalyst that the screening converter is 1 section needs 30 people to work continuously 4 days, and totally 5 sections of converters if screening just needs great amount of manpower fully, need about 20 days consuming time, and operating efficiency is extremely low, and the repair time is very long.According to retrieval, still there is not relevant art applications Chinese patent at present.
Summary of the invention
The purpose of this utility model provides a kind of sulfuric acid catalyst sifter, uses this sifter in a short time vanadium catalyst to be told available catalyst, the useless catalyst of particulate and catalyst powder by its particle diameter, improves the operating efficiency of maintenance.
The sulfuric acid catalyst sifter that the designer provides is made up of screening district and dust storehouse, screening district case top is the inclined-plane, a catalyst suction line and the secondary adjustable pipe of pressing are arranged on it, and enclosure interior has a tilting screen cloth, and available catalyst storehouse and the useless catalyst storehouse of particulate are divided in screening; The useless catalyst storehouse of available catalyst storehouse and particulate has a material outlet respectively; Screening district housing links to each other with the dust storehouse, and a gas channel is arranged between them; Dust is equipped with dust-removal cloth-bag in the storehouse, and air stream outlet is arranged at the top, and the vacuum tube interface is arranged at top.
Above-mentioned catalyst suction line is connected with converter; The secondary adjustable pipe of pressing is connected with the vavuum pump import.
The included angle of above-mentioned screen cloth is 30 °～75 °; Mesh size is 4 * 4～12 * 12mm.
Visor is arranged respectively at the bottom in the useless catalyst storehouse of above-mentioned catalyst storehouse and particulate; Visor is also arranged at the bottom in described dust storehouse, and visor is circular, and its diameter is φ 50mm～φ 150mm.
The filter area of above-mentioned dust-removal cloth-bag is 0.5m
2～1m

The operation principle of sulfuric acid catalyst sifter is: sifter utilizes the vavuum pump negative pressure of vacuum in when operation, catalyst is drawn onto on the screen cloth sieves, and the particulate catalyst sifts, and flows out from the material outlet in the useless catalyst storehouse of particulate; And the qualified catalyst of granularity is stayed on the wire side, falls into available catalyst district, flows out from material outlet and carries out collecting packing on ground, and the catalyst of collection is back to converter again; The catalyst dust enters the dust storehouse by gas channel under vacuum draw, dust storehouse cloth bag relies on vacuum cleaning, and remaining air-flow utilizes the air compressor air storage tank pulse valve to extract out.
Sulfuric acid catalyst sifter of the present utility model, stable, simple to operate, respond well.Compare with the artificial method for sieving of tradition, following advantage is arranged: 1. save the human and material resources resource, alleviate labor strength greatly; 2. the dust recovering effect is good, helps the healthy of environmental protection and operating personnel; 3. screening effect is good, and catalyst grains can be separated fully with dust.
