Abstract
The utility model discloses a gas phase iodine crystallizer. The crystallizer main body is divided into two sections which are two thin-wall cubes or triangles, cylinders or polyhedrons or combination of polyhedrons in different shapes, or combination of cylinders and polyhedrons. The volume of a first section of crystallizer (3) is not less than that of a second section of crystallizer (4). The first section of crystallizer is provided with an iodine steam inlet (1), and the second section crystallizer is provided with a non-condensable gas outlet (7). The two sections of crystallizers are fixed on a common cone base (6) which communicates the two sections of crystallizers. A container is arranged below the cone base (6). The two sections of crystallizers are connected through a connecting bracket (5) and externally connected through a shell bracket (2). According to the gas phase iodine crystallizer provided by the utility model, large-scale industrial production of iodine sublimation and desublimation is realized, thereby laying a solid foundation for industrialized production of iodine purification by adopting a sublimation method.
Description
Technical field
The utility model relates to crystallization, specifically, relates to iodinating and refining Crystallization device equipment.
Background technology
As everyone knows, a kind of important form that iodine exists be association in rock phosphate in powder, but its content is different according to the quality in ore deposit.Phosphorus ore is produced phosphoric acid carry iodine again from phosphoric acid, this technology has been documented in Chinese patent No. 200510003058.2, and " extracting the method for iodine from contain the iodine phosphate ore production in the phosphoric acid,diluted that produces " is inner.But in the process of phosphoric acid production iodine, iodine is present in phosphoric acid by wet process with ionic forms, want to produce a kind of satisfactory smart iodine and just the ionic forms iodine in phosphoric acid,diluted must be oxidized to iodine molecule, and through extraction, absorption, oxidation analyse iodine, filtration, distilling, sublimate etc. just can obtain concentration greater than 99.5% smart iodine, the gas phase iodine crystallizer of mentioning in the application is exactly to satisfy a kind of equipment that smart iodine is produced.The gas phase iodine crystallizer also can satisfy the requirement that other thick iodine (such as the iodine that reclaims other different qualities such as iodine, Iodine, bittern iodine and mineral iodine) is finish-machined to smart iodine.
Summary of the invention
The purpose of this utility model is to provide a kind of gas phase iodine crystallizer, to promote the quality of iodine.
The method and technology scheme that the inventor provides is: a kind of gas phase iodine crystallizer, and this crystallizer main body is divided into two sections, is two thin-walled squares, or triangle body, cylinder or polyhedron, or difform polyhedral combination are perhaps cylinder and polyhedral combination; Wherein the volume of first paragraph crystallizer is not less than the volume of second segment crystallizer; The iodine steam import is arranged on the first paragraph crystallizer, be the main crystal region of iodine, the incoagulable gas outlet is arranged on the second segment crystallizer, be the secondary crystallization district of iodine; On two sections crystallizers were fixed at the bottom of a common cone, the cone end, was communicated with two sections crystallizers, and the cone end is the collector of iodine, was provided with container on cone beneath limit; For adding stiff stability, two sections crystallizers have connection bracket to connect, and the outside connects with outer casing stand.
Above-mentioned crystallizer outside is furnished with special-purpose fan.
A plurality of series connection of above-mentioned crystallizer or the use that is together in parallel.
Above-mentioned crystallizer connects the washing tail gas device in the incoagulable gas outlet, and makes crystallizer keep negative pressure state with the vacuum pump or fan.
Principle of the present utility model is: iodine steam enters the first paragraph of crystallizer from the top of crystallizer, the crystallizer outer wall is thinner, blow with fan the outside, iodine steam condensation in it is got off, become iodine crystal, stick on the crystallizer inwall, do not have a small amount of iodine steam under condensation to enter the second segment of crystallizer from boring the end at first paragraph, again be condensed, incoagulable gas is discharged to the washer or atmosphere of back from the second segment of crystallizer.The distribution of temperature in the crystallization control device can be controlled the size of iodine crystal.Pat the outer wall of crystallizer, under crystallization iodine just can enter cone, the limit fills in the container of iodine.The utility model in use, the iodine in wall not energy product gets blocked uply, being generally 3～5mm left and right will pat, in order to avoid affect the condensation effect of crystallizer.
Advantage of the present utility model: realized iodine distillation, the large-scale industrial production of sublimating.Single covering device per hour can condensation iodine 30 Kg left and right.If at the logical frozen air of import, the load of device can arrive the 50Kg left and right.For the refining purification iodine of sublimed method realizes that suitability for industrialized production provides solid foundation.
