Technical field
The present invention relates to a kind of boiling chloridizing furnace, belong to the titanium tetrachloride preparing technical field with the natural rutile producing titanium tetrachloride t 5 bx.
Background technology
Titanium tetrachloride is to produce the raw material that Titanium Sponge 40-60 mesh and vapour phase oxidation process are produced white titanium pigment, and it makes with chlorinated with chlorine richness titanium material having in the presence of the charcoal.At present domestic method of in industry, producing titanium tetrachloride has fused salt chlorimation and fluidizing chlorination, and employed rich titanium material all is titanium slags.Because the granularity of titanium slag is inhomogeneous; Account for accounting for about 43% below 21%, 200 order greater than 75 purposes, for reaching good effect of settling; Employed boiling chloridizing furnace is adopted the boiling section basal area: the structure of expanding reach basal area=1: 16, the investment cost of stove and maintenance cost height.In addition, rutile fluidizing chlorination success of the test is arranged also at present, but develop at the early-stagely, still have a lot of weak points,, make loaded down with trivial details etc. such as the boiling chloridizing furnace complex structure.These problems all have to be solved.
Summary of the invention
Technical problem to be solved by this invention is, a kind of boiling chloridizing furnace with the natural rutile producing titanium tetrachloride t 5 bx is provided, and this boiling chloridizing furnace investment cost and maintenance cost are low, structure with make simple.
Technical scheme of the present invention: with the boiling chloridizing furnace of natural rutile producing titanium tetrachloride t 5 bx; Integral body has cylinder shape liquid bed steelwork shell; Comprise boiling section; Boiling section connects expanding reach through transition section, when guaranteeing that boiling chloridizing furnace normally moves, and the investment cost and the maintenance cost of having saved boiling chloridizing furnace greatly; Lower end at boiling section offers slag notch, is sealed with the furnace bottom seal closure, in the furnace bottom seal closure, is inserted with Chlorination tube, between furnace bottom seal closure and slag notch, at a distance from being provided with chlorine gas distribution plate, is used to support material, uniform distribution chlorine; One side of boiling section also is provided with filling tube; The upper end of described expanding reach is provided with furnace top cover, on furnace top cover, offers the air outlet.
The opening of described Chlorination tube makes chlorine upwards can evenly get into chlorine gas distribution plate down.
Described chlorine gas distribution plate is the plansifter plate, and percentage of open area is 1.33%.
Sieve aperture on the described chlorine gas distribution plate little tubaeformly for down big, prevents the sieve aperture putty.
Described chlorine gas distribution plate adopts water glass refractory concrete or graphite to process.
The height H of described boiling section is 2-4 a times of boiling section diameter.
Described boiling section is an outer steel shell, and inner lining refractory, the outermost layer of refractory materials are that fire-resistant acid resisting concrete is made layer firm by ramming; The second layer is a fireclay brick; The 3rd layer is the electrode paste molded layer; The 4th layer is fireclay brick; One deck is phosphoric acid salt concrete precast block or high alumina brick.
The liner of described expanding reach is divided into three layers, and the fire-resistant acid resisting concrete of outermost layer is made layer firm by ramming; The inside is two-layer to be clay brick.
The present invention is according to the relatively more uniform characteristics of natural rutile particle; And according to the thermal equilibrium of boiling chloridizing furnace; Being provided with rational structure arranges; Make the ratio of basal area and the basal area of expanding reach of boiling section narrow down to 1: 5.76, thereby when guaranteeing the normal operation of boiling chloridizing furnace, the investment cost and the maintenance cost of having saved boiling chloridizing furnace greatly.In addition; Shelve the chlorine gas distribution plate that has up-small and down-big sieve aperture in the bottom of boiling section, and take rational percentage of open area, make boiling chloridizing furnace have good springiness; The advantage that is easy to operate and control; And make screen perforation not putty and chlorine be evenly distributed, the opening that cooperates Chlorination tube makes chlorine upwards can evenly get into chlorine gas distribution plate down.The present invention has also taked rational inner lining structure to expanding reach and boiling section, and further having strengthened this boiling chloridizing furnace is the chlorination effect of 80-180 purpose natural rutile to granularity.The present invention also has the making characteristic of simple, can wide popularization and application.
