Abstract
The invention discloses a kind of carbonyl iron dust atomization pyrolytic technique, it is characterized in that comprising the iron pentacarbonyl storage device, pyrolysis installation, gathering-device and the after-treatment device that connect successively; Described pyrolysis installation top entry place arranges atomizing nozzle device.The present invention is based on the atomization of liquid, vaporization pyrolysis principle designs, eliminate the evaporimeter that tradition vaporization pyrolytic technique is required, fundamentally solve the problem of frequent cleaning vaporizer in production process, atomization pyrolytic technique also has the large feature of operating flexibility, can be reached by the adjustment of technological parameter that traditional handicraft cannot realize, control arbitrarily the object of powder shape and particle diameter.
Description
Technical field
The present invention relates to and a kind of adopt atomised form that liquid iron pentacarbonyl is sprayed into pyrolysis installation to carry out pyrolysis, prepare device and the technology of carbonyl iron dust, belong to chemical technology field, particularly a kind of carbonyl iron dust atomization pyrolysis plant.
Background technology
Carbonyl iron dust, as the basic material with property, is widely used in the fields such as metallurgy, chemical industry, electronics, military affairs.Preparation process is sponge iron and CO gas synthesizing iron pentacarbonyl under high temperature, high pressure, and iron pentacarbonyl through heat resolve, is produced into carbonyl iron dust and carbon monoxide under specific condition.The carbonyl iron dust of preparation has practicality widely because having the features such as particle diameter is little, iron purity is high, outward appearance is spherical in shape, Electronic Performance is excellent.
In the preparation process of existing carbonyl iron dust, need to carry out high-temperature evaporation to the iron pentacarbonyl passing into pyrolysis reactor, decomposition temperature because of iron pentacarbonyl is 58 DEG C, boiling point is 104 DEG C, iron pentacarbonyl is caused to decompose in a large number at vaporescence, formed on an evaporator and need scabbing of cleaning, blocking pipe, affect the cycle of operation and cause the accident, the decomposition of iron pentacarbonyl also causes very large waste.Parking clean expander frequently causes repeatedly switched system, technological fluctuation again, pyrolytic process can not be carried out under steady temperature and condition, cause product cut size excessive, product purity and Quality Down.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of carbonyl iron dust atomization pyrolysis plant, adopting the atomization of liquid, vaporization pyrolysis, by vaporization and pyrolysis, a step in reaction unit completes, and shape and the particle diameter of carbonyl iron dust can be controlled arbitrarily, product purity is high, steady quality.
The present invention is realized by following technical scheme:
A kind of carbonyl iron dust atomization pyrolysis plant, comprises the iron pentacarbonyl storage device, pyrolysis installation, gathering-device and the after-treatment device that connect successively; Described pyrolysis installation top entry place arranges atomizing nozzle device.
Described iron pentacarbonyl storage device connects measuring pump and desalted water storage tank successively.
Described iron pentacarbonyl storage tank is also connected filter with between atomizer.
Described atomizing nozzle device is connection traffic meter and ammonia surge tank successively.
Described iron pentacarbonyl storage device top also connects nitrogen pipeline.
Described after-treatment device is dividing plate separator after being connected to pyrolysis installation in turn and bag hose.
Described gathering-device has three, is arranged on respectively bottom pyrolysis installation, dividing plate separator and bag hose.
Beneficial effect of the present invention is: the present invention is based on the atomization of liquid, antipyretic principle of vaporizing designs, eliminate the vapourizing unit before conventional pyrolytic device, fundamentally solves the problem of frequent cleaning vapourizing unit in production process; This device can also by the adjustment of technological parameter, reaches that traditional handicraft cannot realize, and controls arbitrarily the object of powder shape and particle diameter.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As Fig. 1, it is structural representation of the present invention, comprise the desalted water storage tank 1, measuring pump 2, iron pentacarbonyl storage tank 3, filter 11, atomizer 13, pyrolysis oven 5, dividing plate separator 7 and the bag hose 9 that connect successively, pyrolysis oven 5, dividing plate separator 7 and bag hose 9; Bottom connects the first collector 6, second collector 8, the 3rd collector 10 respectively; Pyrolysis oven 5 is connection traffic meter 12, ammonia surge tank 4 successively; Pyrolysis oven 5 also connects nitrogen pipeline.
Workflow of the present invention is: the desalted water injecting desalted water storage tank 1 is pressed into iron pentacarbonyl storage tank 3 by measuring pump 2, extrude the pentacarbonyl iron powder of same volume by after filter 11, be atomized, spray into the transposed pyrolysis oven 5 of nitrogen through atomizer 13, heat vaporized decomposition under ammonia atmosphere, generate the carbonyl iron dust and the CO gas that need particle diameter, the larger iron powder of part particle diameter enters the first collector 6, residue iron powder carries out being separated of iron powder and gas with gas by dividing plate separator 7, the iron powder be separated falls into the second collector 8, remain micro-iron powder and CO gas finally enters bag hose 9, carbon monoxide reclaims, final residue iron powder falls into the 3rd collector 10.
