Abstract
The utility model discloses a superheater of an N-methylaniline contact system, which is free from the phenomenon of blocking or hardening of parts in the superheater, and can improve the content stability of N-methylaniline and guarantee the long-period running of equipment. According to the technical scheme, the superheater comprises a tower body with a plurality of heat exchange column pipes, and an upper end socket and a lower end socket which are arranged at the two ends of the tower body; and the superheater is characterized in that pipe plates are arranged between the two ends of the tower body and the upper and lower end sockets, the heat exchange column pipes are arranged between the pipe plates, a tar discharging device is arranged on the lower end socket, a biphenyl inlet is formed in the upper part of the tower body, and a biphenyl outlet is formed in the lower part of the tower body.
Description
Technical field
The utility model relates to a kind of superheater, is specifically related to a kind of methylphenylamine contact system superheater.
Background technology
In the superheater tubulation in traditional methylphenylamine contact system demister is housed, a tar separator is arranged between superheater and contactor.In use, drive to find that in the near future charging is unstable that the fluctuation of methyl alcohol vaporizing pressure and temp is large, the fluctuation of superheater inlet temperature is large, and methylphenylamine content is unstable, simultaneously, also often occurs in superheater and the tar separator stopping up.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model aims to provide a kind of novel methylphenylamine contact system superheater, has improved the stability of methylphenylamine content, is difficult for simultaneously stopping up, and has guaranteed the long-term operation of equipment.
To achieve these goals, the technical solution of the utility model: a kind of methylphenylamine contact system superheater, comprise the tower body with some heat exchanging pipes, and the upper and lower end socket at tower body two ends, wherein, all have tube sheet between described tower body two ends and upper and lower end socket, described heat exchanging pipe is built up between this tube sheet; On described low head, also be provided with tar discharging device.
Further, have the biphenyl import on described tower body top, have the biphenyl outlet in this tower body bottom.
At described low head the compound import is set; At described upper cover the outlet of vaporization material is set.
Has an expansion joint at described tower body middle part.
Also be provided with hanging support in described tower body middle and upper part.
Described heat exchanging pipe is vertical between the described tube sheet, and perpendicularity requires to be 0.06mm.
The beneficial effects of the utility model: be provided with tar discharging device at described low head, can in the situation of not stopping, carry out tar exhausting to whole superheating system, avoid in the superheater each parts to stop up such as tar separator etc., and then affect the stable content of methylphenylamine.Simultaneously, establish the biphenyl import by logical on tower body top, the logical biphenyl of establishing exports in the tower body bottom, further guarantees the stable content of methylphenylamine with the heating of biphenyl chuck.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of methylphenylamine contact system superheater as shown in Figure 1 comprises the tower body 1 with some heat exchanging pipes 5, and the upper and lower end socket 2,3 at tower body 1 two ends, wherein, all have tube sheet 4 between described tower body 1 two ends and upper and lower end socket 2,3, described heat exchanging pipe 5 is built up between this tube sheet 4; On described low head 3, also be provided with tar discharging device 8.
The utility model so that this equipment can carry out tar exhausting in the situation of not stopping, had both been avoided the situation that each parts generation is stopped up in the whole superheating system by at low head 3 tar discharging device 8 being set, and did not affect again normal production simultaneously.Through long-term experiment, tar separator tar exhausting day shift every day in the superheater, in the running in 1 year, occur without clogging, the stable content of methylphenylamine has obtained strong guarantee simultaneously.
In order to guarantee thermal effect, described heat exchanging pipe 5 is vertical between the described tube sheet 4, and perpendicularity requires to be 0.06mm.Simultaneously have biphenyl import 6 on described tower body 1 top, have biphenyl outlet 7 in this tower body 1 bottom.By biphenyl chuck mode of heating, effectively improved the stability of methylphenylamine content, guaranteed the long-term operation of equipment.
At described low head 3 compound import 10 is set; At described upper cover 2 vaporization material outlet 9 is set.To realize the normal production operation of methylphenylamine.
In addition, has an expansion joint 11 at described tower body 1 middle part.Also be provided with hanging support 12 in described tower body 1 middle and upper part.In order to make things convenient for the production of methylphenylamine, guaranteed the stability of whole equipment.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on the specific embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
