Accompanying drawing explanation
Fig. 1 is the structural representation of reactor of the present invention.
Embodiment
Referring now to accompanying drawing, reactor of the present invention is described.Shown in Fig. 1 is the structural representation of reactor, and it comprises the gas distributor 17 being arranged on reactor tank body 8 inside, gas distributor 17 to be positioned at bottom tank body 8 and with the interior bottom wall of 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 by the gas inject of such as carbonic acid gas in tank body 8, fully to react with the reaction solution in tank body 8 and to mix, thus can obtain the higher white carbon black product of quality.
Continue with reference to Fig. 1, reactor of the present invention also comprises the stir shaft 10 stretching into tank body 8, and stir shaft 10 is divided into the stirring shaft part connecting shaft part and be positioned at tank body 8 inside.Wherein, connect shaft part and be connected with electric motor 1, stir shaft part and be fixed with agitating vane 15.
Gas injection is carried out using while promoting that question response thing in reactor (can be such as carbon dioxide and the liquid sodium silicate as reaction solution) reacts in gas distributor 17 pairs of reactors, the stir shaft 10 of tank body 8 inside drives agitating vane 15 to stir treating reactant, therefore question response thing can be made to mix more even, further promote the abundant reaction of reaction solution in such as carbon dioxide and tank body.
More specifically, the surface of gas distributor 17 also offers the carbon dioxide being provided for gas injection sparger 17 and is disposed to pore in tank body 8, and pore is offered towards the interior bottom wall of tank body 8.
When reacting in the reactor, the flow direction of reaction solution enters from tank body 8 top then to flow to bottom tank body 8, after agitating vane 15 stirs, be back to tank body 8 top again bottom tank body 8.That is, reaction solution is with a kind of mode along stir shaft 10 axial flow and carbon dioxide reaction in tank body 8.So the pore direction that gas distributor 17 is offered is consistent with the flow direction of reaction solution, because this increasing the homogeneity of question response substrate concentration in reactor, that is, reaction solution and carbonic acid gas react in the reactor with the state close to complete mixing flow, can improve the quality of white carbon black product further.Preferably, the distance between the agitating vane 15 of gas distributor 17 and foot is the agitating vane 15 of this foot and 1/4 ~ 1/3 of the spacing of tank body 8 interior bottom wall.Time in this distance range, in reactor, the homogeneity of question response substrate concentration is best.Certainly should be appreciated that the scope of above distance can be determined according to concrete service condition, the present invention is not limited to this.
Further, reactor also comprises chuck 11, and chuck 11 is the single piece be made up of first set portion and the second cover portion.Wherein, the outside diapire of the coated tank body in first set portion 8, the periphery wall of the second coated tank body 8 in cover portion.And the heating agent import 20 of chuck 11 can be opened in first set portion, heating agent outlet 12 can be opened in the second cover portion.In other words, the heating agent import 20 of chuck 11 is positioned at the outside diapire of tank body 8, and the heating agent of chuck 11 outlet 12 is positioned at the periphery wall of tank body 8.
Time in concrete use, the heating agent of such as steam or thermal oil can be injected by the heating agent import 20 of chuck 11, thus heat temperature raising is carried out to whole tank body 8.The structure heats temperature rise effect of the chuck 11 of this integral coating tank body 8 outside is better, can promote the reaction in reactor.
In addition, spiral deflector 14 can also be provided with in space between tank body 8 and chuck 11, its along in contrast to the sense of rotation L coiled coil of stir shaft 10 in above-mentioned space, namely, spiral deflector 14 coils in above-mentioned space along direction M, and heating agent import 20 is communicated with heating agent outlet 12.
Continue with reference to Fig. 1, the top of tank body 8 offers the opening for feed 6 for injecting reaction solution, and the outside diapire of tank body 8 offers the discharge port 19 for exporting obtained white carbon black product.In addition, venting port 7 can also be offered in tank body 8 top, and in tank body 8, unreacted carbonic acid gas residual gas can be discharged from venting port 7 and collect, and can re-inject gas feed 21 to reuse after then purifying further.
Alternatively, stir shaft 10 connection shaft part and stir between shaft part and can be connected by shaft coupling 9.And step-down gear 2 can also be connected with between the connection shaft part of electric motor 1 and stir shaft 10.More specifically, step-down gear 2 can be fixed on the outside top of tank body 8 by frame 3, and can be provided with sealing member 5 between the outside top of frame 3 and tank body 8.The connection shaft part of stir shaft 10 can run through sealing member 5 from outside and stretch in tank body 8.
In the reactor shown in Fig. 1, the outside top of tank body 8 can also arrange manhole 4, and operator can monitor from this manhole 4 pairs of inside reactors and overhaul.In addition, the internal side wall of tank body 8 can also be fixed with baffle plate 13, baffle plate 13 can stop and water conservancy diversion the question response thing reacted in tank body 8, to make question response thing flow velocity in tank body 8 more steady, and flow to more stable, thus make question response thing in tank body 8, realize fully reaction.
For example in concrete use, first the liquid sodium silicate of a certain amount of 25 ~ 35% is injected in the tank body 8 of reactor by opening for feed 6 when reaction starts, then opens the agitating vane 15 of reactor.Now, by heating agent import 20 injecting steam or thermal oil, heat temperature raising is carried out to whole reactor.It is to be noted, in an optional embodiment, except utilizing chuck 11 to heat reactor, a gas distributor can also be added again in the interior bottom portion of tank body 8, utilizing this gas distributor can pass into the steam for heating in tank body 8 thus come to heat reactor.Certainly should be appreciated that the mode to reactor heats can be determined according to concrete service condition, the present invention is not limited thereto.
When reactor is heated to 72 DEG C ~ 80 DEG C (being preferably 74 DEG C ~ 78 DEG C), the carbon dioxide of purity more than 40% is introduced in reactor, carbon dioxide forms a large amount of tiny bubble by gas distributor 11, and enter tank body 8 by pore, under the action of forced stirring effect of agitating vane 15, tiny bubble can be broken into more tiny bubble, and the contact area in this way between carbonic acid gas bubble and liquid sodium silicate is larger, thus makes reaction more homogeneous, quick.Then, there is following reaction in the reactor:
nSiO
2×Na
2O+CO
2=nSiO
2↓+Na
2CO
