Description
Technical field
The invention belongs to titanium tetrachloride production technical fields, and in particular to a kind of side of green processing titanium tetrachloride dust-slag collection
Method.
Background technique
During fluidizing chlorination produces titanium tetrachloride, mainly by petroleum coke and rich-titanium material（High titanium slag/rutile）This
A little solid components are added in the middle part of chlorination furnace, and liquid chlorine is sent into after gasification from bottom, form fluidized bed, and chlorination occurs for storeroom
Reaction generates crude titanic chloride gas.A part compared with small particle petroleum coke and high titanium slag/rutile with titanium tetrachloride gases
It is discharged at the top of chlorination furnace together, carries out gas solid separation into rotoclone collector.TiO in high titanium slag/rutile2It is chlorinated into
When titanium tetrachloride, other metal oxides therein can also be chlorinated into corresponding metal chloride, such metal chloride with
Titanium tetrachloride gases enter after rotoclone collector largely condense after enter solid dust-slag collection.
Every 1 ton of titanium tetrachloride of production will generate 0.25t dust-slag collection.Contain the up to petroleum coke of 50%-70% in dust-slag collection
With high titanium slag/rutile, residual components are mainly metal chloride, are lacked in the prior art to the effective of titanium tetrachloride dust-slag collection
Processing method, most enterprises using the method processing accumulated in landfill or lime and after solidify, cause the waste of resource with
The pollution of environment.
Metal chloride in dust-slag collection is met water and is largely dissolved, and the content of chloride ion can reach 100mg/L in aqueous solution
More than, this has seriously been more than the requirement in China's sewage drainage standard to chloride ion content, is unable to direct emission, and direct emission will
Meeting polluted underground water, surface drainage and soil, cause environmental pollution.Therefore, using water-soluble filtering, filtrate is directly injected into 1600m
The mode of underground handles chloride slag, has environmental pollution hidden danger.Accumulation landfill is carried out after solidifying using milk of lime：It will usually give up
Filters pressing, filter residue are carried out after the Plus acidic water slurrying of slag（Referred to as inertia slag）It accumulated, taken out or is implemented from inertia slag burnt
Mine separation；Filtrate obtains solid metallic hydroxide and CaCl after carrying out filters pressing after being neutralized with milk of lime2Solution, solid slag tip
Processing, CaCl2Solution, which is evaporated, is concentrated to get anhydrous calcium chloride.But this process flow is cumbersome, solid waste accumulation can occupy
A large amount of place does not fully achieve the harmless treatment of resource.Therefore, efficient, environmentally protective new work is needed exist for
Skill realizes the comprehensive utilization of resource.
Summary of the invention
In view of the above shortcomings of the prior art, the object of the present invention is to provide a kind of green processing titanium tetrachlorides to gather dust
The method of slag.Titanium tetrachloride dust-slag collection is handled by the way that reasonable technique is arranged, it can be achieved that effective component in dust-slag collection
It sufficiently recycles, realizes the optimization of resource, and solve chloride accumulation environmental pollution caused by underground water and soil.
The present invention provides a kind of methods of green processing titanium tetrachloride dust-slag collection, and this approach includes the following steps：
A, titanium tetrachloride dust-slag collection is dissolved in hydrochloric acid solution, obtains slurry；
B, the slurry in step a is subjected to filters pressing, isolated filter residue and filtrate；
C, the filter residue for obtaining step b is using multistage shaking table joint gravity treatment, isolated petroleum coke and titanium slag；
D, after the filtrate that step b is obtained is filtered, is concentrated, the spray roasting in roaster obtains Fe2O3Powder and contain HCl's
Furnace gas；
E, the furnace gas in step d is cooled to 100 DEG C hereinafter, then absorbing in absorption tower through water after cyclone dust collectors dedusting
Hydrochloric acid solution is formed, is back in step a and uses；Fe2O3Powder, which is packaged, to be sold.
Under preferable case, in step a, the mass fraction of the hydrochloric acid solution is 2-4%.
It is further preferred that the mass ratio of hydrochloric acid solution and titanium tetrachloride dust-slag collection is 3 ︰ 1-6 ︰ 1 in step a.Using this
Material ratio can be such that the chloride in titanium tetrachloride dust-slag collection is completely dissolved.
In the present invention, filter residue is handled by multistage shaking table joint gravity treatment, specific processing step can refer to existing
Technology is selected, and using the processing mode, the titanium slag rate of recovery in filter residue can be made up to 34%, TiO in obtained titanium slag2Grade
90% or so.
Preferably, filtered filtrate and the furnace gas progress heat exchange after dedusting in step e in step d, while realizing filter
The concentration of liquid and the cooling of furnace gas.
Specifically, filtrate is pumped into first in the separator of venturi lower part, after filtering and through cyclone dust collectors dedusting
Furnace gas afterwards carries out heat exchange, is pumped into roaster furnace roof again later, and spraying, acid mist quilt during decline is formed through peracid spray gun
The high-temperature gas heating from bottom to top that burner is served in roaster, is converted to Fe2O3Powder and furnace gas containing HCl gas.
Under preferable case, it is 1.2-1.5 that filtered filtrate, which is concentrated into relative density, is more selected as 1.3.
Preferably, the maturing temperature in roaster is 550-650 DEG C.
According to the present invention, the Fe generated in step d2O3Powder largely passes through Furnace and enters bunker, and small part is passed through
It is melted down again after cyclone dust collectors sedimentation, the Fe in bunker2O3Powder is taken out after being packaged；Furnace gas obtained in step d enters by furnace roof
Cyclone dust collectors remove dust, exchange heat using venturi and filtered filtrate, its temperature is made to reach 100 DEG C hereinafter, gas
Into absorption tower, absorb to form hydrochloric acid solution by water in absorption tower, HCl recovery rate is up to 80% or more, by hydrochloric acid solution
It is used back to step a.
The parameter not being limited in the present invention can refer to this field and carry out conventional selection, to make method of the invention
It can be carried out.
The present invention obtains Fe by the way that filtrate is directly carried out spray roasting2O3The gas of powder and containing hydrogen chloride, hydrogen chloride gas
Body, which forms hydrochloric acid by absorption, to realize recycling for resource with Returning utilization to pulping process, and recycling chlorine reduces to water
The pollution of system and soil, Fe2O3Powder can directly be sold, and realize energy-efficient, harmless to environment to titanium tetrachloride dust-slag collection
With the purpose of resource rational utilization.
