Description
Technical field
The utility model belongs to technical field of chemical, and in particular to a kind of naphthalene evaporator.
Background technology
At home, it is necessary to which the crude naphthalene heating and gasifying of 78 DEG C of crystalline temperatures is entered into reactor in built phthalic anhydride plant
Row production, but carried out in evaporator in the gasification of crude naphthalene, because gasification temperature is high, flow velocity is fast, part crude naphthalene
It can not fully gasify and enter next procedure, the phenomenon of this entrained liquid can cause quick-fried accident after first firing to occur, influence safety is raw
Production, so the catalytic oxidation of the generation phthalic anhydride carried out in using naphthalene as the reactor of raw material is, it is necessary to ensure to use pure
Naphthalene gas, once if having the entrance of naphthalene liquid, because strength of fluid is high, can occur vigorous reaction with catalyst, so that last quick-fried
It is fried.And the evaporation of naphthalene is not complete enough in current evaporator, often there is droplet to enter next process with naphthalene steam；Or be
Pure naphthalene steam can be obtained, is combined using plurality of devices, naphthalene is repeatedly handled, complex process, power consumption is high.
Therefore, completely vaporizing for crude naphthalene in evaporator how is ensured, safety just becomes into next process to be compared
Important the problem of.
The content of the invention
Technical problem to be solved in the utility model is：A kind of naphthalene evaporator is provided, can effective gasified industry naphthalene, and
Separate crude naphthalene gas and liquid, it is ensured that pure crude naphthalene gas enters subsequent processing, and equipment is simple, it is ensured that peace
Entirely.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of naphthalene evaporator, including vaporizer body, main body include cavity wall and cavity, and cavity wall top is provided with gas and gone out
Mouthful, bottom is provided with liquid-inlet, and middle part is provided with high pressure steam inlet；Cavity wall top sets what is extended in oriented cavity to hang
Web plate and multiple curved slabs are provided with arm, cantilever, web plate is located at the top of multiple curved slabs.
It is preferred that, described cantilever is arranged on the center of cavity, is fixedly connected and cavity wall central upper portion position.
It is preferred that, described web plate is provided with some mesh, and web plate size is identical with the cross-sectional sizes of respective cavities.
It is preferred that, described web plate is equidistantly positioned with multiple curved slabs.
It is preferred that, central flat area is maximum in described multiple curved slabs, and two ends reduce successively；Or top curved slab is most
Greatly, reduce successively downwards.
By adopting the above-described technical solution, the beneficial effects of the utility model are：
1. because with the addition of multiple curved slabs, the naphthalene steam formation vortex of evaporation can be made so that heating is evenly abundant,
Steam is heated up than more uniform, and therefore partial drop therein can gasify, reduces the possibility that drop is carried secretly；Curved slab also has
There is the function of certain absorption drop, drop is not entered next process with steam.
2. setting some mesh on web plate, the drop in steam is mainly adsorbed, after aggegation for a period of time, drop can drip
Return in liquid naphthalene, gasify again, it is ensured that the purity of steam in gas.
Therefore, the effective gasified industry naphthalene of the utility model energy, and separate crude naphthalene gas and liquid, it is ensured that it is pure
Crude naphthalene gas enter subsequent processing, equipment is simple, it is ensured that safety.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Wherein, 1- vaporizer bodies；2- cavity walls；3- cavitys；4- cantilevers；5- web plates；6- curved slabs；7- high steams enter
Mouthful；8- liquid-inlets；9- gas vents.
Embodiment
With reference to the accompanying drawings and examples, the utility model is expanded on further.
As shown in figure 1, in the utility model, including vaporizer body 1, main body 1 is included in cavity wall 2 and cavity 3, cavity wall 2
Portion is provided with gas vent 9, and bottom is provided with liquid-inlet 8, and middle part is provided with high pressure steam inlet 7；The top of cavity wall 2 is provided with
Web plate 5 and multiple curved slabs 6 are provided with the cantilever 4 extended into cavity 3, cantilever 4, web plate 5 is located at the upper of multiple curved slabs 6
Side；Web plate 5 is equidistantly positioned with multiple curved slabs 6, and some mesh are provided with web plate 5.
In actual production, naphthalene evaporator major function is to allow preheated liquid naphthalene to be gasified totally into gas naphthalene, except devaporation
In drop；Therefore, first preheated liquid naphthalene is circulated into vaporizer body 1 by liquid-inlet 8, then steamed by high pressure
Vapor inlet 7 be passed through high-pressure and high-temperature steam to liquid naphthalene carry out be brought rapidly up gasification, the naphthalene steam after gasification can carry a small amount of drop to
Upper drift, naphthalene steam can form vortex, so, it is equal that steam heats up comparison by the stop of curved slab 6 in uphill process
Even, therefore drop therein may gasify, it is impossible to which the drop of gasification is then stopped by web plate 5 or curved slab 6, drops back to liquid naphthalene
In gasify again.
So ensure that the purity into the naphthalene steam of next process, it is ensured that the safety of production.
It should be understood that these embodiments are merely to illustrate the utility model rather than limit scope of the present utility model.This
Outer to should be understood that after the content of the utility model instruction has been read, those skilled in the art can make each to the utility model
Plant and change or change, these equivalent form of values equally fall within the application appended claims limited range.
