Description
Technical field
Fused solution is made the prilling granulator of spheric granules product, 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 organic 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.
