Description
Technical field
A kind of fused solution is made the prilling granulator of spheric granules, belong to the fused solution field shaping technique.
Background technology
The chemical products moulding is an important step in the Chemical Manufacture, numerous liquid chemical product needed are made the solid particle form, store, pack, transport and use with convenient, as products such as paraffin, sulphur, rosin, polymer, urea, and some intermediate states are the salt series products of fused solution, as salts such as chemical fertilizer, calcium chloride.The forming technique of fused solution has multiple, and concrete granulating raw material characteristic is depended in the design of its prilling process and selection, and different material has different prilling process, as oil cooling granulating technique, steel band granulating technique, tower granulation technology and other granulating technique etc.Now brief introductory section granulating technique related to the present invention.
The oil cooling granulating technique is that density is formed drop greater than the fused solution of cold oil density by nozzle, spread to cold oil from the top of cold oil liquid level, drop sedimentation in cold oil, cooling move heat, and drop solidifies the back discharges, remove cold oil by centrifugal method, realize the granulation of fused solution.This oil cooling granulating technique exists the granulation ability low, and the Granularity Distribution wide ranges is second-rate, the fine particle problems such as causing oil contamination that suspends in cold oil.
With paraffin is example, and background technology of the present invention is described.
The wax moulding technology has chain disc type piece was moulding technology and water-cooled steel band granulating technique at present.
Chain disc type piece was moulding technology comprises following basic processes, the paraffin fused solution is injected the stainless steel cake wax, cake wax enters the cold house by chain drive, move on parallel layer by layer, indoor liquefied ammonia evaporimeter and the air blast of being provided with is to keep cold house's temperature, the heat of liquid wax is shifted out by cold wind, liquid wax is cooled to wax stone gradually, through switching mechanism wax stone is come off, and obtaining every weight is the piece wax product of 5kg.This wax moulding technology is cooling medium with the air, is about 2 hours cool time, the energy consumption height, and production efficiency is low, and labour intensity is big, and the package unit complexity is huge, and mechanical moving element is many, and fault is frequent.
The basic process of water-cooled steel band granulating technique is via distributing rotary drum to form drop with the paraffin fused solution, be dropped in the steel band upper surface, the steel band lower surface is cooled off by spraying cooling water, the paraffin drop is cooled to solid grain wax, scrape the back by scraper plate and obtain hemispherical sheet grain wax, cooling water recycles.The long-time running meeting reduces the smoothness of steel strip surface, and paraffin adhesion steel band or grain wax are inter-adhesive on steel band.Because the cooling of liquid wax is to move heat indirectly through the steel band single face, and the paraffin thermal conductivity factor is low, therefore, it is low to move the thermal efficiency, needs very long steel band, and floor space is big, generally needs many Granulation Equipments to work simultaneously.
On " research of wax balling technique " (" petroleum refining and chemical industry " rolled up the 8th～12 page of the 8th phase in 1994 the 26th), reported a kind of technology, but do not reported concrete device with the balling-up of gunite realization wax.
