Abstract

The application discloses concentrated tower balance pipeline structure, including the concentrate pans, the concentrate pans with the intercommunication has pipeline and gas phase balance pipeline between the concentrated tower, be provided with the delivery pump on the pipeline, the delivery pump will in the concentrate pans the material carry extremely the concentrated tower, the pipeline both ends connect respectively in the concentrate pans bottom with the concentrated tower top, the gas phase balance pipeline both ends connect respectively in the concentrate pans top with the concentrated tower top. The invention has the advantages that a gas phase balance pipeline is communicated between the top of the concentrated solution intermediate tank and the top of the concentration tower, when the gas phase pressure in the concentrated solution intermediate tank is high, the steam carries the material to be automatically conveyed to the concentration tower, and the problem is effectively solved.

Description

Balanced pipeline structure of concentration tower

Technical Field

The application relates to production of chinlon, in particular to a balanced pipeline structure of a concentration tower.

Background

In the production process of nylon-6, about 65% of recovered materials subjected to triple effect evaporation are sent to a concentrated solution intermediate tank and then sent to a concentration tower for further concentration, so that the concentration is increased to 85%. When 65% of reclaimed materials enter the concentrated solution intermediate tank, because the water content in the materials is 35% and the temperature of the concentrated solution is 125 ℃, a large amount of water vapor is caused to emerge through a water seal tank at the top of the concentrated solution intermediate tank, and meanwhile, the materials flow away along with the water vapor, so that the environmental pollution and the material loss are caused.

Disclosure of Invention

The invention aims to provide a concentration tower balance pipeline structure to overcome the defects of the prior art.

In order to achieve the above object, the present invention provides the following technical solutions.

The embodiment of the application discloses concentrated tower balance pipeline structure, including the concentrated solution pans, the concentrated solution pans with the intercommunication has pipeline and vapor balance pipeline between the concentrated tower, be provided with the delivery pump on the pipeline, the delivery pump will the interior material of concentrated solution pans carries extremely the concentrated tower, the pipeline both ends connect respectively in the concentrated solution pans bottom with the concentrated tower top, vapor balance pipeline both ends connect respectively in the concentrated solution pans top with the concentrated tower top.

Preferably, in the above-mentioned equilibrium pipeline structure of the concentration tower, the top of the intermediate tank for the concentrated solution is connected with a water seal pipeline, and the water seal pipeline extends to the water seal tank.

The invention has the advantages that a gas phase balance pipeline is communicated between the top of the concentrated solution intermediate tank and the top of the concentration tower, when the gas phase pressure in the concentrated solution intermediate tank is high, the steam carries the material to be automatically conveyed to the concentration tower, and the problem is effectively solved.

Drawings

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present application, and other drawings can be obtained by those skilled in the art without creative efforts.

FIG. 1 is a schematic diagram showing the configuration of the equilibrium line of the concentration column in an embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1, the equalizing pipeline structure 100 of the concentration tower includes a concentrated solution intermediate tank 100, a conveying pipeline 300 and a vapor equalizing pipeline 400 are communicated between the concentrated solution intermediate tank 100 and the concentration tower 200, a conveying pump 500 is disposed on the conveying pipeline 300, the conveying pump 500 conveys the material in the concentrated solution intermediate tank 100 to the concentration tower 200, two ends of the conveying pipeline 300 are respectively connected to the bottom of the concentrated solution intermediate tank 100 and the top of the concentration tower 200, and two ends of the vapor equalizing pipeline 400 are respectively connected to the top of the concentrated solution intermediate tank 100 and the top of the concentration tower 200. The top of the concentrate intermediate tank 100 is connected with a water seal pipeline 600, and the water seal pipeline 600 extends to the water seal tank 700.

Among this technical scheme, communicate a gas phase balance pipeline between the top of concentrate pans and the concentrated tower top, when gas phase pressure is big in the concentrate pans, vapor takes the material to carry to the concentrated tower from gas phase balance pipeline by oneself, has solved this problem effectively.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

The foregoing is directed to embodiments of the present application and it is noted that numerous modifications and adaptations may be made by those skilled in the art without departing from the principles of the present application and are intended to be within the scope of the present application.
