Description
Technical field
The present invention relates to iodine, also relate to phosphoric acid, specifically, relate to the device that from phosphoric acid by wet process, extracts iodine.
Background technology
Iodine is a kind of scarce resource.Iodine can be used for producing many Industrial products and chemical reagent; Iodine has germicidal action, therefore can be used as sterilant; Iodine still is a kind of trace element of needed by human; The product of iodine deep processing has the fine chemical product of wide market outlook especially.But present iodine scarcity of resources, and in the prior art, extract the iodine resource apparatus and be mostly traditional packing tower, exist filler to be prone to obstruction, short drawback of extraction tower operational cycle, the extraction cost of iodine resource is high.
In the Chinese patent DB, relating to the patented claim part that extracts iodine has No. 200820301317.9 " iodine extraction extraction tower ", No. 200910102772.5 " method of extraction iodine from contain the iodine Rock Phosphate (72Min BPL) ", No. 201010144399.2 " are the heating means that raw material extracts extraction agent in the iodine process to contain the iodine Rock Phosphate (72Min BPL) " etc.The extraction plant that these technical schemes are used remains the equipment of prior art.
Summary of the invention
The object of the invention provides a kind of extraction plant that from phosphoric acid by wet process, extracts rare iodine resource, extracts iodine efficient to improve, and reduces production costs, and reduces energy consumption.
The contriver is in order to put forward the periodic percentage extraction; The device of invention must make spe medium evenly and fully contact with the phosphoric acid acid solution; Guarantee its residence time, reinforcing mass transfer process to greatest extent, the extraction plant that from phosphoric acid by wet process, extracts rare iodine resource that therefore provides is a housing and two chambers cylindrical device of inner core composition; In the inner core is inner room, is the mistress between housing and the inner core; Inner core is the porous cylindrical shell of set aperture, and the inner room top has circular top cover, top cover center to have the import of phosphoric acid acid solution; Circular bottom plate is arranged at the bottom of the inner room, and rotor is equipped with in base plate central authorities, and the eddy current baffle plate is installed on the chamber; The domatic cover plate is all arranged at mistress's top and bottom, has the spe medium outlet on the domatic cover plate of top, has the acid solution outlet on the slope shape plate of bottom, and the middle part is equipped with ring-like porous fabrics device; Around the shell wall bottom and the inner room base plate all have the spe medium import.
Above-mentioned eddy current baffle plate be shaped as the right-angled trapezium shape, right-angled trapezium shape baffle plate vertically is installed on the inwall, baffle plate and inner room axially parallel.
Totally 8 on above-mentioned eddy current baffle plate eddy current baffle plate, per 4 eddy current baffle plates are one deck, the eddy current baffle plate divides and two-layerly relatively is installed on the chamber.
Above-mentioned spe medium outlet is 2, is distributed in the both sides of mistress's top center symmetrically.
Spe medium import around the above-mentioned shell wall is 10, and symmetry, radial distribution is in the bottom of barrel wall equably, and the spe medium access to plant is evenly distributed like this.
Above-mentioned acid solution outlet is 2, is distributed in the both sides of mistress bottom centre symmetrically.
The spe medium bottom inlet of above-mentioned inner room base plate is 2, is distributed in the both sides of bottom centre symmetrically.
Above-mentioned rotor has the helical impeller and is fixed on the base plate with wear ring, and rotor is connected with PWR PLT through rotating shaft.
Principle of work of the present invention is: the phosphoric acid acid solution gets into inner room from the acid solution import, and acid solution is done the high-speed screw motion with rotor, and with spe medium contact mass transfer from the spe medium import; The acid solution of doing high-speed screw motion at inner room receives the effect of cf-and inwall vesicular structure, dishes out along the inner core tangential direction, carries out countercurrent mass transfer the mistress and from the spe medium of spe medium import; From acid solution and spe medium mass transfer process that the inner core tangential direction is dished out, receive the effect of ring-like porous fabrics device, carry out redispersion, discharge from the acid solution outlet at last.
The present invention compares with traditional iodine extraction element has following advantage: 1. because rotor has the helical impeller and inner core is provided with the eddy current baffle plate, acid solution and spe medium are able to prolong duration of contact, and extraction efficiency improves; 2. acid solution is done the spiral motion that surpasses universal gravity constant far away at inner room, in super gravity field, carries out mass transfer with spe medium, and mass-transfer efficiency is high; 3. the acid solution of doing high-speed screw motion at inner room in the effect lower edge of cf-and inwall vesicular structure the inner core tangential direction dish out, get into mistress and spe medium and carry out counter current contact, the extraction efficiency height of iodine; 4. rotor has the helical impeller, need not any filler, and the phosphoric acid acid solution can not stopped up, and realizes long-time effectively smooth running; Therefore 5. plant bulk is little, simple in structure, and rotor only adopts a secondary dynamic seal to be fixed on the lower shoe, makes, installation, maintenance is very convenient.
