Description

Condensation kettle

Technical field

This utility model relates to naphthalene system production equipment technical field, particularly to a kind of condensation kettle.

Background technology

Traditional naphthalene system product processes includes: melts naphthalene, sulfonation, condensation and neutralizes several step, adopt a still that crude naphthalene (purity is not high) carries out molten naphthalene during molten naphthalene, molten naphthalene adds the material (concentrated sulphuric acid) of sulfonation in still after terminating, sulfonation adds the material (mainly formaldehyde) of condensation in still after terminating, in adding in still more afterwards, the material (mainly alkali liquor) of sum is neutralized, final production goes out the naphthalene water reducer of liquid, pulverizable naphthalene water reducer after drying and processing. Whole process carries out in a still, need in the condensation process to control the temperature in still, and this still is advantageous for the still of molten naphthalene, the detection being not used in still temperature, experience only by workman judges a temperature range in still, can affect the quality of naphthalene product after condensation if it is determined that inaccurate.

Utility model content

The utility model proposes a kind of condensation kettle, solve the problem that cannot accurately control formaldehyde dripping quantity in prior art.

Condensation kettle of the present utility model, including: kettle and be arranged on the feeding mouth on described kettle, gas outlet, discharging opening and formaldehyde filler, it is characterized in that, also include being positioned at the formaldehyde filling apparatus above described formaldehyde filler, described formaldehyde filling apparatus includes: formaldehyde container, dropper and flow controller, described dropper and formaldehyde reservoir, flow controller is arranged on described dropper, and described dropper and described formaldehyde filler are tightly connected.

Wherein, described gas outlet is provided with connection flexible pipe.

Wherein, described gas outlet is tightly connected with being connected flexible pipe.

Wherein, described gas outlet be connected between flexible pipe and be additionally provided with thermal insulation layer.

Wherein, also including the puddler being arranged in condensation kettle and the driver being positioned on kettle, described driver connects puddler.

Wherein, also include: the thermowell for inserting thermometer being arranged on described kettle, described thermowell edge is sequentially provided with heat-barrier material ring and soft rubber ring from inside to outside.

The formaldehyde filling apparatus of condensation kettle of the present utility model is for automatically controlling opening or closing of dropper according to the parameter preset, to reach accurately to control the effect of formaldehyde infusion volume. And need not manually drip, it is to avoid the formaldehyde injury to human body.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described 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 premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is this utility model one condensation kettle structural representation;

Fig. 2 is the enlarged diagram of formaldehyde filling apparatus in Fig. 1.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

Condensation kettle of the present utility model is as shown in Figure 1, including: kettle 1 and be arranged on the feeding mouth 2 on described kettle 1, discharging opening 3, gas outlet 4 and formaldehyde filler 16 (certainly also including: observation panel 9, water inlet 11, steam inlet 12, standby mouth 13, steam condensate (SC) outlet 14 and recirculated water entrance 15 etc.), gas outlet 4 for aerofluxus to keep pressure in still. In order to accurately control formaldehyde dripping quantity, also including the formaldehyde filling apparatus 17 being positioned at above formaldehyde filler 16, formaldehyde filling apparatus 17 can be fixed on kettle 1 by support, and is positioned at above formaldehyde filler 16. This formaldehyde filling apparatus 17 is as in figure 2 it is shown, include: formaldehyde container 171, dropper 172 and flow controller 173. Dropper 172 connects with formaldehyde container 171, and flow controller 173 is arranged on dropper 172, and dropper 172 and formaldehyde filler 16 are tightly connected. Flow controller 173 is for automatically controlling opening or closing of dropper according to the parameter preset, to reach accurately to control the effect of formaldehyde infusion volume. And need not manually drip, it is to avoid the formaldehyde injury to human body.

In order to reclaim the naphthalene of volatilization, gas outlet 4 is provided with connection flexible pipe 5. Connect flexible pipe 5 for the gas outlet 4 of this molten naphthalene still being connected to the naphthalene retracting device on production line, to be reclaimed by the naphthalene of volatilization, it is to avoid the waste of material, it is prevented that air pollution. What connect flexible pipe 5 has flexibility, not by the restriction in production line space, arranges more convenient. Further, gas outlet 4 is tightly connected with being connected flexible pipe 5, to prevent the naphthalene leakage of volatilization. Gas outlet 4 be connected between flexible pipe 5 and be additionally provided with thermal insulation layer, it is prevented that kettle 1 overheated with scorch connection flexible pipe 5.

In the present embodiment, also including the puddler 7 being arranged in condensation kettle and the driver 8 being positioned on kettle 1, described driver 8 connects puddler 7. Driver 8 drives puddler 7 to rotate in still, with the material in stirred tank, makes condensation reaction more thorough. It is also the mouth sealed that certain puddler stretches into the opening in still.

For the ease of the temperature in detection kettle, this condensation kettle also includes: being arranged on the thermowell 6 for inserting thermometer 10 on kettle 1, thermowell 6 edge is sequentially provided with heat-barrier material ring and soft rubber ring from inside to outside. Heat-barrier material environmental protection card soft rubber ring will not contact with kettle 1, in case soft rubber ring is ruined, soft rubber environmental protection card plays sealing function after inserting thermometer 10. The kettle 1 of the condensation kettle of the present embodiment is provided with the thermowell 6 for inserting thermometer 10, may be inserted into thermometer in whole condensation reaction, by the observation panel 9 Real Time Observation temperature in the kettle on kettle 1.

The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
