Abstract
The utility model discloses a titanium tetrachloride oxidation reactor spouts salt and removes scar device, including saltcellar, star type unloading valve and titanium tetrachloride oxidation reactor, the pipeline who is used for carrying the salt grain is connected through the star type unloading valve that establish the lower part to the saltcellar, and star type unloading valve can be established and adjust the converter of rotatory frequency control with the salt volume, the titanium tetrachloride oxidation reactor conversion zone is equipped with the through -hole, adopt the flange to be connected with salt grain pipeline, the salt grain through star type unloading valve in the saltcellar enters into the conveyer pipe, the use carrier gas is sprayed the salt grain in the titanium tetrachloride oxidation reactor, depend on its strong scouring action to the titanium tetrachloride oxidation reactor wall, eliminate the scar layer, adopt the above -mentioned mandatory scar method of removing, the system pressure that can effectively prevent titanium tetrachloride oxidation reactor from scarring and lead to is high, the not smooth scheduling problem of air current, ensure titanium tetrachloride oxidation reactor's long period run.
Description
Technical field
The utility model relates to a kind of oxidation reactor grit blast except scar device, especially relates to the gas phase oxidation reactor spray salt of titanium tetrachloride except scar device.
Background technology
Chlorination process prepares the main method of high-grade rutile titanium white powder, titanium tetrachloride gaseous oxidation is critical process prepared by titanium white chloride, oxidation reactor is nucleus equipment prepared by titanium white chloride, its long-standing subject matter is that the oxidation reactor cycle of operation is short, cycle short key factor is that the titanium dioxide granule generated scabs in oxidation reactor, cause system pressure rising, air-flow smooth, and be forced to blowing out.
Summary of the invention
The utility model is for technical problem to be solved, there is provided a kind of and can spray the titanium tetrachloride oxidation reactor spray salt device of salt except scar, by adding in titanium tetrachloride oxidation reactor by salt grain larger for hardness, by it, scar layer is removed to the strong souring of titanium tetrachloride oxidation reactor wall.
The technical scheme that the utility model adopts is: this titanium tetrachloride oxidation reactor spray salt device comprises salt cellar, star-like baiting valve and titanium tetrachloride oxidation reactor.Described salt cellar connects the transport pipe for carrying salt grain by baiting valve star-like set by bottom; The conversion zone of described titanium tetrachloride oxidation reactor is provided with through hole, adopts flange to be connected with salt grain transport pipe; Salt grain enters in transfer lime by star-like baiting valve from described salt cellar, uses carrier gas to be ejected in titanium tetrachloride oxidation reactor by salt grain.
Described salt cellar is provided with pressurising, pressure relief device; And corresponding seal approach is taked to total interface.
Further scheme is, described star-like baiting valve is provided with frequency transformer, can control salt adding amount by regulating star-like baiting valve rotation frequency.
Further again, described carrier gas can be oxygen, nitrogen or chlorine.
The beneficial effects of the utility model are: join in titanium tetrachloride oxidation reactor by carrier gas by the injection of salt grain, by its strong souring to titanium tetrachloride oxidation reactor wall, remove scar layer, adopt above-mentioned mandatory except scar method, effectively can prevent titanium tetrachloride oxidation reactor from scabbing and the problem such as the system pressure caused is high, air-flow is not smooth, guarantee the long-term operation of titanium tetrachloride oxidation reactor.
Accompanying drawing explanation
Fig. 1 is this utility structure schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, this titanium tetrachloride oxidation reactor spray salt, except scar device, is made up of salt cellar 1, star-like baiting valve 2 and titanium tetrachloride oxidation reactor 3 etc.
Salt cellar 1 connects the transport pipe for carrying salt grain by the star-like baiting valve 2 set by bottom, and star-like baiting valve 2 is provided with frequency transformer 4, and frequency transformer 4 can control salt adding amount by regulating the rotation frequency of star-like baiting valve 2; The conversion zone of titanium tetrachloride oxidation reactor 3 is provided with a through hole, adopts flange to be connected with salt grain transport pipe; Salt grain enters in salt grain transport pipe by star-like baiting valve 2 from salt cellar 1, uses oxygen, nitrogen or chlorine to be ejected in titanium tetrachloride oxidation reactor 3 conversion zone by salt grain as carrier gas.
Salt cellar 1 is provided with pressurising, pressure relief device; Corresponding seal approach is taked to total interface.
Concrete operations: during salt adding, first carry out pressure release to salt cellar 1, carry out salt adding operation at ambient pressure in salt cellar 1; After salt adding completes, pressurising is carried out to salt cellar 1, and keeps 0.3MPa pressure, also other arbitrary force value of desirable 0.3-0.5MPa; Start star-like baiting valve 2, the adjustment frequency transformer 4 arranged by it controls lower salt amount, and set of frequency gets 15HZ; Nebulizer gas pressure remains on 0.4MPa, or gets other value between 0.35-0.5MPa, salt grain is spurted into the conversion zone of titanium tetrachloride oxidation reactor 3, removes scar layer by it to the strong souring of titanium tetrachloride oxidation reaction wall.
