Description
Technical field
The present invention relates to the preparation of titanium tetrachloride, relate in particular to boiling chloridizing furnace.
Background technology
Adopt of the titanium tetrachloride of chloridising production both at home and abroad has the sieve plate boiling chloridizing furnace more at present, its advantage is that fluid bed is set up stable in the stove, easy to control, equipment is simple, making is easy, but the sieve plate eyelet stops up easily, thereby causes channel, production target is worsened, even be forced to blowing out, so to the having relatively high expectations of titaniferous material (natural rutile, synthetic rutile, high titanium slag etc.), particularly calcium, magnesium addition content has relatively high expectations.China is titanium resource big country, and 95% titanium ore is the rock ore deposit, and impure magnesium, calcium are higher, it is 7～10% that the high titanium slag that makes through arc melting generally contains Mgo+Cao, the magnesium of producing in chlorination process, calcium chloride present molten condition under normal running temperature, stop up the sieve plate eyelet easily, and production can not normally be carried out, must blowing out change sieve plate, replacement cycle is frequent, and generally at 20～30 days once, labour intensity is big, operational danger is big, has seriously restricted fluidizing chlorination production.For this reason, people have developed no sieve plate fluidizing chlorination technology, rely on the air inlet on the furnace bottom cone to replace gas distribution grid (sieve plate) to go up hundreds of aperture, and air-flow is evenly distributed.As Chinese patent ZL200320130822.9 " circular seam type fluidized bed chlorinator without perforated-plate ", certain effect is arranged to changing original sieve plate fluidizing chlorination short and easy obstruction service time that has.
Summary of the invention
The object of the present invention is to provide a kind of multi-laminar flow cribriform-plate-free boiling chloridization furnace, by reasonable furnace, bottom construction, layering feeds chlorine, and the fluidization that forms stable continuous with titaniferous material is reacted, and produces titanium tetrachloride.
Technical scheme of the present invention:
Chlorination furnace body of heater of the present invention is cylinder and pyramid type, bell is a back taper, gas vent is housed respectively on the bell, venting and temperature-measuring port, the bell deadweight that is connected to of bell and body of heater compresses and is connected, there is the sealing of refractory material sealing gasket the junction, body of heater is made of outer box hat and inner lining refractory, body of heater is divided into four sections, the first stove section is the cylindrical boiling section that is, temperature-measuring port is equipped with on its top, its underpart has the flange of flange and furnace bottom to adopt bolt to be connected to make chlorination furnace in aggregates, flexible sealing ring between the flange of this flange and furnace bottom, seal, the second stove section is conical, on the second stove section material inlet is housed, the 3rd stove section also is conical, and its cone angle is bigger than the second stove section, and the 4th stove section is the cylindrical expanding reach that is, furnace bottom is a monoblock type multilayer chlorine store chamber structure, divide 1～5 layer of chlorine store chamber, every layer of chlorine store chamber has chlorine flow opening and the chlorine air inlet that is circular layout, and the chlorine air inlet connects chlorination tube respectively, every chlorination tube disposes the automatic adjusting apparatus of chlorine flowrate, but the multilayer layering feeds chlorine, realizes multilayer stream, and mud hole is equipped with in the furnace bottom middle and lower part.
Multi-laminar flow cribriform-plate-free boiling chloridization furnace of the present invention (1) has overcome the susceptible to plugging disadvantage of sieve plate stove sieve plate eyelet, (2) the air-flow multilayer enters, make material be dispersed in bed, (3) the bed inwall is streamlined, help material movement, (4) if meet coherent mass, it can be deposited on awl and discharge from slag-drip opening at the end, and (5) can give first-class furnace bottom earlier, adopt the fluidised form furnace technology, furnace temperature is easy to control, it is simple, easy to operate to prevent that furnace lining fusing and other type of furnace from relatively having equipment concurrently, advantages such as the duration of runs is long are the novel type of furnaces of a kind of very practical and effective.
