Abstract
The utility model discloses a liquid acid anhydride insulating tube, its characterized in that: including heat preservation (1), it is article style of calligraphy structure to be equipped with three root canals in heat preservation (1). The beneficial effects of the utility model are that: with two steam conduits near in liquid acid anhydride pipe below, three root canals are the article style of calligraphy after, says three root canals and comes into operation after keeping warm with insulation material, ensures that two kinds of materials can not direct contact and corrode the pipeline to reduce the work load of overhauing.
Description
Technical field
The utility model belongs to a kind of liquid acid anhydride process units, particularly relates to a kind of liquid acid anhydride thermal insulation pipe.
Background technique
At present, in liquid acid anhydride production process, general is all that employing steam tube penetrates in liquid acid anhydride pipe and guarantees that liquid acid anhydride does not solidify, but the steam tube in this sample liquid acid anhydride pipe is if any leakage, and steam and liquid acid anhydride carry out reaction and become highly acid material corrosion pipeline and line clogging is affected and normally produce.
Summary of the invention
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provide a kind of simple and reasonable, guarantee that two kinds of materials can not directly contact and the liquid acid anhydride thermal insulation pipe of corrosion pipeline.
The technical solution adopted in the utility model is such: a kind of liquid acid anhydride thermal insulation pipe, is characterized in that: comprise thermal insulation layer, is provided with three pipes in Chinese character pin-shaped structure in described thermal insulation layer.
Described Chinese character pin-shaped structure is that two steam tubes are located at below liquid acid anhydride pipe.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: abutted against by two steam lines below liquid acid anhydride pipe, three pipes are in Chinese character pin-shaped, after come into operation after the insulation of three pipeline thermal insulating materials, guarantee that two kinds of materials can not directly contact and corrosion pipeline, thus reduce the workload of maintenance.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Mark in figure: 1 is thermal insulation layer, and 2 is liquid acid anhydride pipe, and 3 is steam tube.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of liquid acid anhydride thermal insulation pipe, comprise thermal insulation layer 1, two steam tubes 3 are abutted against below liquid acid anhydride pipe 2 by steam tube 3 and liquid acid anhydride pipe 2, and three pipes are in Chinese character pin-shaped, after come into operation after the insulation of three pipeline thermal insulating materials, the steam tube 3 of such bottom produces the liquid acid anhydride pipe 2 on heat heating top, guarantees that two kinds of materials can not directly contact and corrosion pipeline, reduces the workload of maintenance.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
1. a liquid acid anhydride thermal insulation pipe, is characterized in that: comprise thermal insulation layer (1), is provided with three pipes in Chinese character pin-shaped structure in described thermal insulation layer (1).
2. liquid acid anhydride thermal insulation pipe according to claim 1, is characterized in that described Chinese character pin-shaped structure is that two steam tubes (3) are located at below liquid acid anhydride pipe (2).
