Description
Technical Field
The utility model belongs to titanium tetrachloride production facility field, concretely relates to dust treatment device in titanium tetrachloride production.
Background
In the production process of titanium tetrachloride, solid dust contained in gas generated by a boiling chlorination furnace needs to be removed by a dust removal device, and for the treatment of the solid dust, manufacturers adopt a method of adding water and lime to neutralize the solid dust at present, and the method has two disadvantages: firstly, a large amount of lime and water are consumed, so that the economy is not reasonable; but valuable metals (zirconium, niobium, vanadium and the like) in the solid dust are all discarded in a white way, and the principle of recycling waste is not met.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a dust treatment device in titanium tetrachloride production can be through cooling, airtight collection with the solid dust for draw the valuable metal of dust the inside, with solve the problem that waste water and lime, valuable metal can not be retrieved at present, carry out the condensation with the titanium tetrachloride gas of taking over in the dust simultaneously and retrieve, reduce extravagantly.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is:
a dust treatment device in titanium tetrachloride production comprises a dry ash bin and a condenser, wherein the top of the dry ash bin is provided with a dust inlet and a gas outlet, the dust inlet is connected with a dust remover through a pipeline, the gas outlet is connected with the condenser through a collecting pipe, and the bottom of the dry ash bin is connected with a dry ash collecting device through an ash discharge valve; the bottom of the condenser is connected with the collecting tank, and a negative pumping pipeline is arranged on the condenser to pump out non-condensable gas.
And a cooling water jacket is arranged on the outer wall of the dry ash bin, and circulating cooling water is introduced into the cooling water jacket.
The dry ash bin is internally and vertically provided with a partition plate, and the partition plate is positioned between the dust inlet and the gas outlet.
The collection tank is connected with the crude titanium tetrachloride tank.
By adopting the technical scheme, the utility model discloses following beneficial effect has:
① the method of discharging solid dust is modified, so that no more lime and water are consumed in the process of treating the solid dust.
② the utility model can effectively collect the dry dust in the dust, and solves the problem that valuable metals in the solid dust can not be recovered.
③ the utility model can condense and recycle the titanium tetrachloride gas brought out from the dust, thus reducing waste.

Detailed Description
The following detailed description of the present invention is provided with reference to the accompanying drawings and examples, but not to be construed as limiting the present invention in any way.
Referring to fig. 1, a dust treatment apparatus for titanium tetrachloride production is provided for treating solid dust separated by a dust collector in titanium tetrachloride production again to collect dry ash therein and separate titanium tetrachloride from the solid dust. The device comprises a dry ash bin 1 and a condenser 2, wherein the top of the dry ash bin 1 is provided with a dust inlet so as to be connected with a dust remover through a pipeline, the pipeline is provided with an electromagnetic valve, one side of the dust inlet is also provided with a gas outlet, the gas outlet is connected with the condenser 2 through a collecting pipe 5, the collecting pipe 5 is provided with the electromagnetic valve, the bottom of the dry ash bin 1 is in a conical shape, the lowest point of the dry ash bin is connected with a discharge pipe, the discharge pipe is connected with a collecting bag or a closed collecting device below the discharge pipe, and the discharge pipe is provided with an; the condenser 2 is internally provided with a frozen brine as a condensing medium for condensing titanium tetrachloride gas entering the condenser 2, the condensed titanium tetrachloride flows out of a discharge valve at the bottom of the condenser 2 to a collecting tank 3, the collecting tank 3 is connected with a crude titanium tetrachloride tank 6 through a pipeline, the condenser is also provided with a negative pumping pipeline 8, and non-condensable gas in the gas entering the condenser 2 is pumped out to an overhaul negative pumping system through the negative pumping pipeline 8.
Furthermore, a cooling water jacket is further arranged on the outer wall of the dry ash bin 1, and circulating cooling water is introduced into the cooling water jacket to cool dust in the dry ash bin 1.
Further, a partition plate 7 is arranged in the dry ash bin 1, and the partition plate 7 is positioned between the dust inlet and the gas outlet so as to prevent dust from entering the gas outlet.
When the dust remover is used, solid dust is discharged from the dust remover and then enters the dry dust bin 1, and the dust in the solid dust falls into the bottom of the dry dust bin 1 and is bagged in batches through the dust discharge valve 4; gas contained in the solid dust enters a condenser 2 through a collecting pipe 5, the gas contains titanium tetrachloride gas, nitrogen and the like, the titanium tetrachloride is condensed into liquid through the condenser 2, the liquid flows into a collecting tank 3 below to be collected, after a certain amount of titanium tetrachloride liquid is collected by the collecting tank 3, the titanium tetrachloride liquid is discharged into a crude titanium tetrachloride tank 6, and non-condensable gas such as nitrogen is pumped into an overhauling negative pumping system through a negative pumping pipe 8.
The embodiments selected for the purpose of disclosing the invention are presently considered to be suitable, but it is to be understood that the invention is intended to cover all variations and modifications of the embodiments, which fall within the spirit and scope of the present invention.
