Background technology
Zinc oxide (ZnO) is the oxide compound of zinc, dissolves in acid and highly basic, but is insoluble in water.Zinc oxide is widely used in plastics, silicate product, synthetic rubber, lubricating oil, paint, ointment, tackiness agent, food, battery, fire retardant, makeup, printing and dyeing, papermaking, enamel and cable as a kind of conventional chemical additive, etc.Along with the continuous quickening of industrial process, the demand of zinc oxide constantly increases, simultaneously also day by day harsh to its performance requriements.
The method of producing zinc oxide mainly contains dry method and wet method two kinds, but mostly adopt dry method, dry method has direct method and indirect method, and direct method also claims method produced in USA, is be that raw material is through boiling sintering desulfuration with zinc ore concentrate, briquetting is mixed again with tackiness agent, coal dust etc., introduce to maintain in stove and steam zinc, then by zinc fume oxidation (zinc fume contacts with air), draw through the pipeline as zinc oxide collection device, obtain zinc oxide product, the micro-shape of this product is needle-like; Indirect method also claims method national law, be take zinc ingot metal as raw material, first through melting and scumming, then proceed to high temperature crucible and in special oxidizing chamber, zinc fume is oxidized at 1250-1300 DEG C, draw through the pipeline as zinc oxide collection device, obtaining micro-shape is spherical zinc oxide product.
Because the particle of the zinc oxide of directly drawing from the pipeline as zinc oxide collection device is larger, thus need to carry out follow-up pulverizing and/or selection by winnowing operation is implemented refinement and separates fineness grade according to different purposes, thus cause process tediously long, the shortcoming that energy consumption is large, cost is high.
Chinese patent Authorization Notice No. CN201678713U recommends " rotary kiln end lower zinc oxide collection device ", it is that the flue gas containing low-grade zinc oxide coming from rotary kiln end is introduced sedimentation in primary monomer sludge box, and secondary bag-type dust case introduced by the vacuum fan on the pipeline of the flue gas entered in primary monomer sludge box through being arranged on the transmission pipeline be connected between primary monomer sludge box and secondary bag-type dust case, by the Bag filter be arranged in secondary bag-type dust case, air cleaning unit process is separately arranged or introduced to air after filtration outward, trifle in the world is then collected in secondary bag-type dust case, regularly to remove, specifically can see the 0022nd section to 0024 section, the specification sheets of this patent.
By understanding the full text of above-mentioned CN201678713U, known its is not be zinc oxide collection device truly, but belongs to environmental protection and energy saving facility category, does not thus have referential technical meaning for collecting the zinc oxide be oxidized by zinc fume.
Known according to above-mentioned explanation, if the zinc oxide of the fine particle shape be gathered on cloth bag can be collected, so certainly can avoid the waste of zinc oxide, to economize on resources to greatest extent, but be showed no in disclosed patent and non-patent literature at present and allly have corresponding technology to enlighten.
