Description
Technical field
The invention belongs to crude titanic chloride production technical field, and more particularly to one kind is without sieve plate fluidizing chlorination system.
Background technology
Industrial production crude titanic chloride is typically using fluidizing chlorination, two kinds of fused salt chlorimation method at present.Domestic fluidizing chlorination system
System has the type of furnaces such as ￠ 800, ￠ 1200, ￠ 1600, ￠ 2400, ￠ 2800, ￠ 3600, and with the development of technology, domestic enterprise has opened introduction
External large-scale chlorination technique and equipment with application, to improve product yield and quality, such as ￠ 3000, the ￠ 4000 in the U.S., Japan
Boiling chloridizing furnace, because external fluidizing chlorination technology uses rutile mostly（TiO2 content >=95%, granularity requirements are harsh）Make
For raw material, thus used between chlorination furnace and dust-precipitator to cross pipeline connecting structure thinner（As shown in Figure 1）, but because China is not gold
The place of production of red stone, rutile need to rely on import, and rutile cost of material is high, causes its production cost high, product city competitiveness
Weak, therefore, the enterprise of domestic Introduced From Abroad fluidizing chlorination technology is intended to using domestic high titanium slag as raw materials for production, in the hope of drop
Low cost, premenstruum (premenstrua) research and improvement, some enterprises can reach high using 50% country using external fluidizing chlorination technology
Titanium slag raw material, but influenceed by the chlorination furnace structure and high titanium slag raw material introduced, the plugging problem ratio between chlorination furnace and dust-precipitator
It is more serious, it is easily caused yield reduction, environmental pollution, the problems such as labor intensity is big.
The content of the invention
To solve the problems, such as plugging between chlorination furnace and dust-precipitator present in prior art, invention proposes providing one kind
Without sieve plate fluidizing chlorination system, the fluidized bed chlorinator without perforated-plate that can be achieved to introduce all using domestic high titanium slag raw material when do not occur
Phenomena such as passageway blocks, so as to improve chlorination production efficiency, reduce production cost.
Technical scheme is as described below：
It is a kind of without sieve plate fluidizing chlorination system, mainly by chlorination furnace, bitubular dust-precipitator, rotoclone collector and elution device according to
Secondary connection composition, the top of bitubular dust-precipitator are provided with one high and one low two cylinders that gather dust of front stage, and two front stages are gathered dust cylinder
The conical lower portion that bottom is set is connected by motor-operated control valve with collection slag ladle, and collection slag ladle bottom is by motor-operated control valve with receiving slag ladle
Connection, chlorination furnace top are provided with the vertical tube short circuit of cross four-way, and vertical tube short circuit is connected by transverse tube short circuit with bitubular dust-precipitator,
The internal diameter of transverse tube short circuit is more than 2/3rds of chlorination furnace burner hearth internal diameter.
Further, mouth spray is provided with the top of the vertical tube short circuit and transverse tube short circuit, the top of vertical tube short circuit,
The prime of bitubular dust-precipitator is gathered dust at the top of cylinder, the rear class of bitubular dust-precipitator is gathered dust, and cylinder is connected on transverse tube with rotoclone collector, the bitubular
The conical lower portion of dust-precipitator is respectively equipped with temperature measuring equipment.
Further, the receipts slag ladle, which is provided with, neutralizes agitating device, neutralizes agitating device and is made up of circulating pump and pipeline.
Further, the spray equipment in the temperature measuring equipment, motor-operated control valve and mouth spray is respectively with automatically controlling
System connection.
In the present invention, it is connected using cross four-way vertical tube short circuit with chlorination furnace, auxiliary spray is set in vertical tube short circuit
Mouth is drenched, due to cross four-way structure, can facilitate and be operated in plugging handling；The internal diameter of transverse tube short circuit is designed as chlorination furnace burner hearth
More than 2/3rds of internal diameter, using this transverse tube short circuit internal diameter expanded, it can be ensured that not plugging, installed on transverse tube short circuit
Mouth spray, the titanium tetrachloride of spray is not liquefied into dust-precipitator bottom and is influenceed to arrange dust-slag collection, and can reach cooling and require；
Motor-operated control valve is used between bitubular dust-precipitator flange in the bottom and collection slag ladle, deslagging number and time can be controlled more conveniently；
Motor-operated control valve is used between collection slag ladle bottom and receipts slag ladle, can control the deslagging time, receives slag ladle using pump circulation stirring neutralization
Enter aftertreatment systems afterwards；Temperature measuring equipment is installed on bitubular dust-precipitator, it is ensured that bitubular dust-precipitator bottom temp is not less than control
While temperature processed, adjust automatically spray flux.
The advantages of the present invention mainly have：
It is existing that passageway blocking etc. does not occur when realizing the fluidized bed chlorinator without perforated-plate introduced all using domestic high titanium slag raw material
As so as to improve chlorination production efficiency, reducing production cost.
