Brief description
Fig. 1 is the structural representation of reactor of the present invention.
Specific embodiment
Reactor referring now to the Description of Drawings present invention.Fig. 1 is illustrated that the structural representation of reactor, and it includes arranging
Gas distributor 17 within reactor tank body 8, gas distributor 17 is located at tank body 8 bottom the interior bottom wall with tank body 8
Separately.In addition, the gas feed 21 of gas distributor 17 is arranged at the side-walls of tank body 8.Further, gas distributor 17 can
To be injected into the gas of such as carbon dioxide in tank body 8, fully to be reacted with the reactant liquor in tank body 8 and to be mixed, from
And quality higher white carbon black product can be obtained.
With continued reference to Fig. 1, the reactor of the present invention also includes the shaft 10 stretching into tank body 8, and shaft 10 is divided into
Connect shaft part and be located at the stirring shaft part within tank body 8.Wherein, connect shaft part and be connected with motor 1, stirring shaft part is fixed with and stirs
Mix blade 15.
Carry out gas injection to promote question response thing in reactor in gas distributor 17 is to reactor（It can be for example dioxy
Change carbon gas and the liquid sodium silicate as reactant liquor）While reaction, the shaft 10 within tank body 8 drives stirring vane 15
It is stirred treating reactant, therefore so that the mixing of question response thing is more uniform, further promote such as titanium dioxide
The abundant reaction of reactant liquor in carbon gas and tank body.
More specifically, the surface of gas distributor 17 is further opened with the carbon dioxide for making gas injection distributor 17
Gas is emitted into the pore in tank body 8, and pore opens up towards the interior bottom wall of tank body 8.
When being reacted in the reactor, the flow direction of reactant liquor is to enter from tank body 8 top to then pass to tank body 8 bottom,
It is back to tank body 8 top from tank body 8 bottom again after agitated blade 15 stirring.That is, reactant liquor is to be stirred with a kind of edge in tank body 8
Mix the axle 10 axially mode of flowing and carbon dioxide reaction.So the pore direction that gas distributor 17 opens up is and reactant liquor
Flow to consistent, therefore increased the homogeneity of question response thing concentration in reactor, i.e. reactant liquor and carbon dioxide are with close to complete
The state of mixed flow is reacted in the reactor, can improve the quality of white carbon black product further.Preferably, gas distributor 17 with
The distance between stirring vane 15 of foot, distance between the stirring vane 15 for this foot and tank body 8 interior bottom wall
1/4～1/3.When in this distance range, in reactor, the homogeneity of question response thing concentration is optimal.It should be understood, of course, that more than
Depending on the scope of distance can be according to specifically used situation, the present invention is not limited to this.
Further, reactor also includes chuck 11, and chuck 11 is the single piece being made up of first set portion and second set of portion.Its
In, first set portion coats the outside diapire of tank body 8, and second set of portion coats the periphery wall of tank body 8.And the heat-carrying agent of chuck 11 enters
Mouth 20 can be opened in first set portion, and heat-carrying agent outlet 12 can be opened in second set of portion.In other words, the heat-carrying of chuck 11
Medium entrance 20 is located at the outside diapire of tank body 8, and the heat-carrying agent of chuck 11 outlet 12 is located at the periphery wall of tank body 8.
The heat-carrying of such as steam or conduction oil when specifically used middle, can be injected by the heat-carrying agent import 20 of chuck 11
Medium, thus carry out heat temperature raising to whole tank body 8.The structure heat temperature raising of the chuck 11 outside this integral coating tank body 8
Effect more preferably, can promote the reaction in reactor.
Additionally, being also provided with spiral deflector 14 in space between tank body 8 and chuck 11, it is along in contrast to stirring
The direction of rotation L coiled coil of axle 10 is in above-mentioned space, i.e. spiral deflector 14 coils in above-mentioned space along direction M, and
And heat-carrying agent import 20 is connected with heat-carrying agent outlet 12.
With continued reference to Fig. 1, the top of tank body 8 offers the charging aperture 6 for injecting reactant liquor, and the outside diapire of tank body 8 is opened
It is provided with the discharging opening 19 for exporting obtained white carbon black product.In addition, tank body 8 top can also open up air vent 7, in tank
In body 8, unreacted carbon dioxide residual gas can be discharged from air vent 7 and be collected, can be again after then purifying further
Injection gas feed 21 is to be reused.
Alternatively, can be connected by shaft coupling 9 between the connection shaft part of shaft 10 and stirring shaft part.And motor
Reductor 2 can also be connected between 1 and the connection shaft part of shaft 10.More specifically, reductor 2 can be solid by frame 3
Due to the outside top of tank body 8, and sealing member 5 between the outside top of frame 3 and tank body 8, can be provided with.Shaft 10
Connect shaft part to run through sealing member 5 from outside and stretch in tank body 8.
In reactor shown in Fig. 1, the outside top of tank body 8 can also arrange manhole 4, and operator can be from this manhole
4 pairs of inside reactors are monitored and overhaul.In addition, the internal side wall of tank body 8 can also be fixed with baffle plate 13, baffle plate 13 is permissible
The question response thing being reacted in tank body 8 is stopped and water conservancy diversion, so that question response thing flow velocity in tank body 8 is more flat
Surely, and flow to more stable, so that question response thing realizes abundant reaction in tank body 8.
For example in specifically used, first by a certain amount of 25～35% liquid sodium silicate by entering when reaction starts
Material mouth 6 is injected into the stirring vane 15 then opening reactor in the tank body 8 of reactor.Now, by heat-carrying agent import 20 note
Enter steam or conduction oil to carry out heat temperature raising to whole reactor.It is pointed out that in an optional embodiment, removing
Using chuck 11, reactor is heated, a gas distributor can also be added again in the interior bottom portion of tank body 8, profit
The steam for heating can be passed through with this gas distributor thus reactor is heated into tank body 8.It should be understood, of course, that
Depending on the mode that reactor is heated can be according to specifically used situation, the invention is not limited in this.
When reactor is heated to 72 DEG C～80 DEG C（It is preferably 74 DEG C～78 DEG C）When, by the carbon dioxide of purity more than 40%
Gas is introduced in reactor, and carbon dioxide forms a large amount of tiny bubbles by gas distributor 11, and enters tank by pore
Body 8, under the action of forced stirring of stirring vane 15 acts on, tiny bubble can be broken into more tiny bubble, by this side
Contact area between formula carbon dioxide bubble and liquid sodium silicate is bigger, so that reaction is more homogeneous, quick.Then, exist
There is following reaction in reactor：
nSiO2×Na2O+CO2=nSiO2↓+Na2CO3
Reacted white carbon finished product is discharged from discharging opening 19, and in tank body 8, unreacted carbon dioxide residual gas can
To discharge from air vent 7 and to collect, after then purifying further, gas feed 21 can be re-injected to be reused.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
