Background technology
In existing Molten salt chlorination furnace production process, one or more levels dust chamber device of whole employing, for separating of the high-boiling point salt in mixed gas gas, but no matter be one-level or multistage dust chamber, all high-boiling point salt in mixed gas gas cannot be separated to more than 90%, by still carrying a large amount of high-boiling point salts in the mixed gas gas of dust chamber, this part high-boiling point salt can deposit in follow-up drip washing condenser system, and enters TiCl with the circulation of system material
4in storage tank, cause TiCl
4degradation, and then affect TiCl
4the operating performance of refining system.
According to statistics, the efficiency that current single-stage dust chamber is separated high-boiling point salt is 35%, namely has the high-boiling point salt of 65% to enter elution circuit groove tank, according to TiCl in elution circuit circulation groove
4liquid sampling analysis finds, AlCl
3content accounts for 35%, FeCl
3content accounts for 56%, and solid content is 200g/L, and boiling point is relative to TiCl
4higher, due to high-boiling point salt too high levels, cause submerged pump and annex serious wear on circulation groove, and can cause fouling in the corresponding double pipe cooler of submerged pump, heat exchange efficiency reduces, and direct influential system balance, finally causes TiCl
4quality product declines.
Utility model content
The purpose of this utility model is just to provide a kind of problem solving a large amount of high-boiling point salt of mixed gas gas entrainment in Molten salt chlorination furnace production process, makes the TiCl produced
4high-boiling point salt parting furnace in the fused salt chlorimation mixed gas that percentage of product improves.
To achieve these goals, the technical solution adopted in the utility model is: high-boiling point salt parting furnace in a kind of fused salt chlorimation mixed gas, comprise submerged pump on body of heater and circulation pulp tank, the furnace wall of described body of heater is from inside to outside successively by refractory brick, refractory materials packing layer and carbon steel shell composition, described body of heater is made up of burner hearth and two vertical spray cylinders, described spray cylinder top is provided with spray header, described spray header is communicated with submerged pump on circulation pulp tank by shower, be communicated with burner hearth bottom described spray cylinder, inlet mouth and air outlet is respectively equipped with in the upper end of described two spray cylinders,
As preferably, described burner hearth internal diameter is 1.3-4m;
As preferably, described spray cylinder internal diameter is 0.4-1mm;
As preferably, the spacing sprinkler spacing between described two spray cylinders is at 0.2-0.6mm;
As preferably, described burner hearth offers top salt outlet, burner hearth bottom offers bottom salt outlet.
Compared with prior art, the utility model has the advantage of: the utility model structure is simply easy to use, solve in Molten salt chlorination furnace production process, in mixed gas gas, carry the problem of a large amount of high-boiling point salt secretly, make the TiCl produced
4percentage of product improves, and makes AlCl
3, FeCl
3separate from mixed gas gas Deng high-boiling point salt, separation efficiency is up to 99%.
