Abstract
The utility model relates to a naphthalene is production equipment technical field, discloses a sulfonating reactor, be in including the cauldron body and setting feed inlet, gas outlet and discharge gate on the cauldron body, install two way pipelines rather than the intercommunication on the discharge gate. The utility model discloses an install two way pipeline adapters rather than the intercommunication on sulfonating reactor's the discharge gate, consequently can be used in a production line with sulfonating reactor on, can all be used for the sulphonate by whole cauldron when the sulphonate, the naphthalene after will sulfonating has again improved sulfonated efficiency respectively through among two leading -in solitary condensation kettle in two way pipelines like this, it is the production efficiency of product also to have improved whole naphthalene.
Description
Technical field
The utility model relates to naphthalene system products production equipment technical field, in particular to a kind of sulphonation kettle.
Background technology
Traditional naphthalene system product processes comprises: melts naphthalene, sulfonation, condensation and neutralizes several steps, adopt a still that NAPTHALENE FLAKES. (INDUSTRIAL GRADE） (purity is not high) is carried out molten naphthalene during molten naphthalene, molten naphthalene adds the material (vitriol oil) of sulfonation in still after terminating, sulfonation adds the material (being mainly formaldehyde) of condensation in still after terminating, in adding in still more afterwards, the material (being mainly alkali lye) of sum neutralizes, final production goes out liquid naphthalene water reducer, pulverizable naphthalene water reducer after drying and processing. Whole process all carries out in a still, owing to material usage ratio in every a one-step process is different, in Four processes, reaction material amount ratio is 1:3:6:2, naphthalene and the vitriol oil after sulfonation reaction generate 3 parts of naphthene sulfonic acid, namely when condensation reaction, the ratio of naphthene sulfonic acid and formaldehyde is 1:2, therefore this still is equivalent to only have 1/2 for the utilization ratio of the vitriol oil, it is seen that the efficiency of sulfonation is extremely low. And production process has a small amount of naphthalene evaporate, it is thus desirable to naphthalene is recycled.
Practical novel content
The utility model proposes a kind of sulphonation kettle, solve all flow processs in prior art and all carry out and cause the inefficient problem of sulfonation in same still (not having production line).
Sulphonation kettle of the present utility model, the opening for feed comprising still body and being arranged on described still body, air outlet and discharge port, described discharge port is provided with the two-way pipeline adaptor being connected with it, described air outlet is provided with connecting hose.
Wherein, each joint of described two-way pipeline adaptor is equipped with flowrate control valve.
Wherein, described air outlet and described connecting hose are tightly connected.
Wherein, thermofin also it is provided with between described air outlet and connecting hose.
The discharge port of sulphonation kettle of the present utility model is provided with the two-way pipeline being connected with it, therefore sulphonation kettle can be used on a production line, when sulfonation can whole still all for sulfonation, again the naphthalene after sulfonation is imported in two independent condensation stills by two-way pipeline respectively, which enhance the efficiency of sulfonation, also improve the production efficiency of whole naphthalene system product.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, it is briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of sulphonation kettle of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only the utility model part embodiment, instead of whole embodiments. Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The sulphonation kettle of the present embodiment is as shown in Figure 1, comprising: still body 1 and opening for feed 2, first steam-in 31, the 2nd steam-in 32, porthole 4, air outlet 5, discharge port 6, water of condensation discharge outlet 11, sewage draining exit 12 and the mouth for subsequent use 13 that are arranged on still body 1, air outlet 5 is for being vented to keep pressure in still. Discharge port 6 is provided with the two-way pipeline adaptor 8 being connected with it. Two-way pipeline adaptor 8 is for connecting two-way pipeline, and two-way pipeline connects the condensation still of the next stage of naphthalene system production technique. Because the amount ratio of the material of the vitriol oil and condensation is 1:2, therefore, each road pipeline of two-way pipeline is respectively used to connect the opening for feed of condensation still (altogether two condensation stills). Sulphonation kettle special like this carries out sulfonation, and output can bring up to original twice, thus improves the efficiency of sulfonation and the production efficiency of whole flow process.
In the present embodiment, due to next stage corresponding two condensation temperature in the kettle of each sulphonation kettle, the difference of pressure, the flow velocity of the liquid naphthalene sulfonic acid in two-way pipeline may be caused different, in order to accurately control to flow into the amount of the naphthene sulfonic acid of each condensation still so that condensation reaction is more accurate, each joint of two-way pipeline adaptor 8 is equipped with flowrate control valve 9, when reaching the amount of the naphthene sulfonic acid needed for condensation still, flowrate control valve 9 cuts out automatically. This avoid in follow-up two condensation stills naphthene sulfonic acid in a still excessive, the problem of naphthene sulfonic acid deficiency in another still.
In the present embodiment, air outlet 5 being provided with connecting hose 7, connecting hose 7, for the air outlet 5 of this sulphonation kettle is connected to naphthalene retrieving arrangement, to be reclaimed by the naphthalene of volatilization, avoids the waste of material. Connecting hose 7 there is flexibility, not by the restriction in production line space, arrange more convenient.
Further, air outlet 5 and connecting hose 7 are tightly connected, and avoid naphthalene to leak. Also being provided with thermofin between air outlet 5 and connecting hose 7, namely the inwall of connecting hose 7 is enclosed within the outer wall of air outlet 5 by thermofin, prevents still body 1 overheated to scorch connecting hose 7.
The foregoing is only better embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
