Description of drawings
Fig. 1 is the structural representation of titanium tetrachloride washing absorption device of the present utility model.
Embodiment
Referring to Fig. 1, a kind of titanium tetrachloride washing absorption device of the present utility model comprises that successively the one-level rapids rushes washing tower 1, secondary rapids and rushes washing tower 2, three grades of packing towers 3 and level Four packing tower 4.The one-level rapids rushes on the circulation fluid pipeline that washing tower 1, secondary rapids rush washing tower 2, three grades of packing towers 3 and level Four packing tower 4 pump 6 all is installed, and pump 6 is exported to the one-level rapids and rushes on the circulation fluid pipeline that washing tower 1, secondary rapids rush washing tower 2, three grades of packing towers 3 and level Four packing tower 4 interchanger 5 all is installed.Wherein, the air outlet, top that the one-level rapids rushes washing tower 1 is connected to the inlet pipe that described secondary rapids rushes washing tower 2, the air outlet, top that the secondary rapids rushes washing tower 2 is connected to one-level packing tower 3 inlet pipe by pipeline, and the air outlet at one-level packing tower 3 tops is connected to secondary filler 4 tower inlet mouths by pipeline; The one-level rapids rushes washing tower 1 and the secondary rapids rushes washing tower 2 shared slush-pit launder 9, and one-level packing tower 3 and secondary packing tower 4 share subsiders 10.
Air outlet, secondary packing tower 4 top is connected on mist eliminator 11 inlet mouths by pipeline.One-level packing tower 3, secondary packing tower 4 all dispose shower nozzle.Be provided with on pump 6 and interchanger 5 pipelines on valve 7, pump 6 and the titanium tetrachloride mud return system pipeline and be provided with valve 8.
The principle of work of titanium tetrachloride washing absorption device of the present utility model is described below in conjunction with Fig. 1:
Mixing furnace gas after dust collecting system is processed enters one-level rapids among Fig. 1 and rushes washing tower 1 and carry out washing absorption, under the washing absorption of circulation fluid, the titanium tetrachloride gases of mixing in the furnace gas is condensed into titanium tetrachloride liquid, mixing simultaneously in the furnace gas entrained solid particle and condensed titanium tetrachloride liquid enters 1 grade of rapids and rushes at the bottom of washing tower 1 tower, and the titanium tetrachloride gases that is not condensed enters the secondary rapids and rushes in the washing tower 2 with mixing furnace gas, and entrained solid particle and the titanium tetrachloride gases that is not condensed carry out washing absorption in the furnace gas to mixing again.In the above-mentioned titanium tetrachloride washing absorption process, mix titanium tetrachloride gases in the furnace gas and constantly be washed to absorb and enter at the bottom of the tower in the circulation fluid, then by overflow port the titanium tetrachloride liquid under the washing absorption is drained in the slush-pit launder 9.
In the above-mentioned titanium tetrachloride washing absorption process, if the unlatching that then keeps valve 7 when the circulation fluid solid content is low at the bottom of the tower continues that the one-level rapids is rushed the mixing furnace gas that washing tower 1 and secondary rapids rush in the washing tower 2 and carries out washing absorption; If the circulation fluid solid content is higher, then valve-off 7, and Open valve 8 is delivered to mud return system by the circulation fluid that pump 6 is high with solid content.In the above-mentioned titanium tetrachloride washing absorption process, the titanium tetrachloride gases that guarantees to mix in the furnace gas can washing absorption, rush the pipeline that washing tower 1 and secondary rapids rush between the washing tower 2 at pump discharge to one-level rapids and dispose interchanger 5, heat transferring medium is that normal-temperature water cools to circulation fluid respectively.
Circulation fluid is cooled as heat transferring medium through the two-stage normal-temperature water, the entrained solids particle is very low in the mixing furnace gas after employing circulation fluid washing absorption is processed, enter and carry out washing absorption in the one-level packing tower 3, mix titanium tetrachloride gases in the furnace gas be condensed into titanium tetrachloride liquid and enter tower at the bottom of as circulation fluid, and the titanium tetrachloride gases that is not condensed enters in the secondary packing tower 4 with mixing furnace gas, again the titanium tetrachloride gases that is not condensed is carried out washing absorption.In the above-mentioned titanium tetrachloride washing absorption process, mix titanium tetrachloride gases in the furnace gas and constantly be washed to absorb and enter at the bottom of packing tower 3,4 towers in the circulation fluid, then by overflow port the titanium tetrachloride liquid under the washing absorption is drained in the subsider 10.
In the above-mentioned titanium tetrachloride washing absorption process, if the unlatching that then keeps valve 7 when the circulation fluid solid content is low at the bottom of the tower continues the mixing furnace gas in one-level packing tower 3 and the secondary packing tower 4 is carried out washing absorption; If the circulation fluid solid content is higher, then valve-off 7, and Open valve 8 is delivered to mud return system by the circulation fluid that pump 6 is high with solid content.In the above-mentioned titanium tetrachloride washing absorption process, for improving the washing absorption efficient of titanium tetrachloride, guarantee that the titanium tetrachloride gases of mixing in the furnace gas can fully be washed absorption, dispose interchanger 5 at pump discharge to the pipeline between one-level packing tower 3 and the secondary packing tower 4, heat transferring medium is-25～-30 ℃ chilled brine.
Top exit place at secondary packing tower 4 is provided with mist eliminator 11, removes the liquid particle in the mixed gas behind the washing absorption.
