Description
Technical field
This utility model relates to the technical field of chlorination legal system titanium dioxide, the chlorination legal system titanium dioxide of a kind of continuously-running
Device.
Background technology
Chloride process titanium dioxide produce oxidation unit refer to be refined by chlorination the pure titanium tetrachloride sent here preheated after and compound modifying agent trichlorine
Change aluminum mixing, joined in oxidation reactor by charging ring and generate titanium dioxide with the high-temperature oxygen fast reaction through twice preheating
Titanium and chlorine, and reduce the temperature to about 200 DEG C by quench zone and cooling pipe, then with gas-solid separation equipment by titanium dioxide,
Chlorine and other gas carry out the process separated, and block impact to prevent the titanium dioxide generated from scabbing in the duct and produce, need
Quench zone adds except scar agent.
Existing chloride process titanium dioxide process units is the crude titanic chloride generated by chlorination furnace, condensed refined after deliver to oxidation unit with
High-temperature oxygen fast reaction generates titanium dioxide base material and chlorine, locates after being delivered to by the titanium dioxide base material obtained after cooled separation
Reason prepares titanium dioxide product, and chlorine is returned to again chlorination furnace and recycles.Titanium white chloride is produced there is high automatization, company
Continuous productionization and the productive prospecting with loop, but one of them link breaks down, and all can cause whole production line
Pausing, only after Resolving probiems, whole device could put into production from newly, as in chloridizing unit generation line clogging or set
For when extremely need to overhaul, chlorination furnace will stop into chlorine temporarily, thus the chlorine that oxidation unit produces will be unable to return to chlorination furnace,
Cause oxidation unit also will to stop simultaneously, make the system of whole chlorination legal system titanium dioxide not run continuously.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of temporarily stopping by chlorination furnace to be affected into chlorine, oxidation unit
Remain to the device of the chlorination legal system titanium dioxide run continuously.
The device of the chlorination legal system titanium dioxide of the technical scheme is that continuously-running of this utility model, including the chlorination of connection
Device and oxidation unit, described chloridizing unit includes oxidation reactor that chlorination furnace, described oxidation unit include being sequentially communicated, cold
But pipeline, gas-solid separation equipment, chlorination furnace connects with oxidation reactor, also includes chlor-alkali liquid chlorine device, in chlorination furnace and oxidation
It is provided with the pure titanium tetrachloride storage tank that can store certain pure titanium tetrachloride amount between reactor, is sequentially communicated after gas-solid separation equipment
Chlorine water circulating cooling tower, sulfuric acid tower, acid mist demister, turbine, chlorine water content and temperature after treatment is had to reach
Can be with the requirement of carbon steel material conveying, described turbine all connects with chlorination furnace and chlor-alkali liquid chlorine device, normally gives birth at chloridizing unit
In the case of product, the chlorine that oxidation unit produces can return to chlorination furnace and recycles；Feelings in chloridizing unit temporary parking maintenance
Under condition, still ensure that the lasting supply of oxidation unit material and the chlorine of generation can be processed by chlor-alkali liquid chlorine device, thus ensure that
The continuous operation of chlorination legal system titanium dioxide device.
Further, be respectively arranged with between turbine and chlor-alkali liquid chlorine device and chloridizing unit chlorination furnace the first stop valve,
Two stop valves, can need, by the chlorine gas transfer of generation to chlorination furnace or chlor-alkali liquid chlorine device, to make oxidation unit even according to producing
Continuous even running.
The beneficial effects of the utility model are:
1, the stop frequency of the oxidation unit caused because of chloridizing unit maintenance is reduced.
2, because of the minimizing opening stop frequency of oxidation unit, and then the labor intensity of operator is reduced.
3, because of the minimizing opening stop frequency of oxidation unit, thus the operating cost of whole device is reduced.
4, allow titanium white production device combine with chemical industry for making chlorine and alkali device, make the device energy long-term smooth of chlorination legal system titanium dioxide transport
OK, it is ensured that stablizing of chloride process titanium dioxide powder yield.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Figure is labeled as: 1-pure titanium tetrachloride storage tank, 2-oxidation reactor, 3-cooling pipe, 4-gas-solid separation equipment, 5-chlorine
Water circulating cooling tower, 6-sulfuric acid tower, 7-acid mist demister, 8-turbine, 9-the first stop valve, 10-second cuts stop valve,
11-chlorination furnace, 12-chlor-alkali liquid chlorine device, 13-after-treatment device.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Embodiment:
Embodiment 1:
As it is shown in figure 1, when chlorination furnace 11 is properly functioning, the second stop valve 10 is opened, the first stop valve 9 cuts out, chlorine
The petroleum coke, the high titanium slag that return to chlorination furnace 11 and join in chlorination furnace 11 react generation crude titanic chloride, then obtain after refined
It is sent to oxidation unit to pure titanium tetrachloride, thus reaches recycling of chlorine.
Embodiment 2:
As it is shown in figure 1, when chloridizing unit needs temporary parking to overhaul, and when chlorination furnace 11 stops into chlorine, the second stop valve 10 closes
Closing, the first stop valve 9 is opened, and the pure titanium tetrachloride needed for oxidation unit runs is provided by pure titanium tetrachloride storage tank 1, preheated
Device mixes with aluminum chloride after preheating temperature to 350-450 DEG C in Alchlor generator, and temperature is heated to
450-550 DEG C, join in oxidation reactor 2 by charging ring, arrive 1500-1800 DEG C high with temperature after twice preheating
Temperature oxygen fast reaction generates titanium dioxide base material and chlorine, and reduces the temperature to 200-300 DEG C by cooling pipe 3, then uses
Gas-solid separation equipment 4 carries out isolated titanium dioxide base material and high temperature chlorine.The titanium dioxide base material obtained is sent to post processing
Device 13 makes titanium dioxide product, and high temperature chlorine cools through chlorine water circulating cooling tower 5, and heat is passed through cold by heat exchanger
Freezing water to take away, the chlorine after cooling, because of aqueous, need to be dried with sulfuric acid tower 6, make chlorine water content reach to use carbon
Steel material conveying requirement, it is raw to chlor-alkali liquid chlorine device 12 that the chlorine after acid mist demister 7 carries out pressure-increasing unit with turbine 8 again
Production fluid chlorine products, thus ensure that oxidation unit energy continuous and stable runs, enable the yield of titanium dioxide to stablize.
