Abstract
The utility model discloses a kind of rectifier column reflux device, comprise the return duct being installed on rectifying column tower top, return duct branch is connected with symmetry and disjunct liquid sealing pipe, the top of liquid sealing pipe is connected with return duct, the middle and upper part of liquid sealing pipe is connected with lower liquid pipe by distributing pipe, and the bottom of distributing pipe is higher than the top of return duct.Fluid-tight structure is provided with in this liquid sealing pipe.All the time liquid is filled with in this return duct.The design feature of rectifier column reflux device is that part adds the fluid-tight structure in liquid sealing pipe and liquid sealing pipe in the tower of return duct, return duct is connected with the top of liquid sealing pipe, lower liquid pipe is connected by the middle and upper part of distributing pipe with fluid-tight structure, the bottom of distributing pipe is higher than the top of return duct, such structure ensure that return duct is full of liquid all the time, also be the key thoroughly getting rid of hammering generation, eliminate in return duct the situation having gas-liquid to coexist, completely avoid because high temperature gas enters return duct and occur the possibility of " hammering " phenomenon.
Description
Technical field
The utility model relates to a kind of technical field of rectifier column reflux device, particularly relate to a kind of to be applied on rectifying column and to solve gas-liquid coexist and be back to the rectifier column reflux device of rectifying column.
Background technology
In Chemical Manufacture, the use of rectifying column is very general, and the operation of rectifying column can not lack the step of overhead reflux, not so cannot reach desirable separating effect; And, if reflux design is too simple, beyond thought puzzlement can be suffered, time in cooled feed back to rectifying column, owing to there is the possibility that gas-liquid coexists, the abnormal sound that can cause in return duct as hammering, either large or small; The existence of abnormal sound not only increases the psychological burden of operative employee, long-term vibrations and impact are caused to the filler of rectifying column, connector and tower internals etc., can cause that filler is broken, connector leaks, tower internals breaks, singly do not shorten the life-span of equipment, add maintenance of equipment amount, also add security risk.
For the reflux of rectifying column, traditional way is that the end of simple part in the tower of return duct connects an elbow, phegma is imported the first-stage tank of liquid distribution trough in tower, but such way existing defects, when capacity of returns changes, capacity of returns may be not enough to ensure that the interior part of the tower of return duct is full of liquid all the time, can cause the situation having gas-liquid to coexist in return duct like this, the gaseous phase materials of high temperature contacts in pipeline with the withdrawing fluid of low temperature, causes the generation of " hammering " phenomenon.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome above-mentioned prior art, a kind of rectifier column reflux device is provided, this rectifier column reflux device solves " hammering " problem that rectifier column reflux pipe may occur, for preventing the generation of this phenomenon, first ensure that return duct is full of liquid at any time, there will not be the situation that gas-liquid coexists, the design feature of this rectifier column reflux device is that part adds the fluid-tight structure in liquid sealing pipe and liquid sealing pipe in the tower of return duct, return duct is connected with the top of liquid sealing pipe, lower liquid pipe is connected by the middle and upper part of distributing pipe with fluid-tight structure, the bottom of distributing pipe is higher than the top of return duct, such structure ensure that return duct is full of liquid all the time, also be the key thoroughly getting rid of hammering generation.
The utility model solves the technical scheme that its technical problem adopts: a kind of rectifier column reflux device, comprise the return duct being installed on rectifying column tower top, return duct branch is connected with symmetry and disjunct liquid sealing pipe, the top of liquid sealing pipe is connected with return duct, the middle and upper part of liquid sealing pipe is connected with lower liquid pipe by distributing pipe, and the bottom of distributing pipe is higher than the top of return duct.Fluid-tight structure is provided with in this liquid sealing pipe.All the time liquid is filled with in this return duct.
In sum, the design feature of rectifier column reflux device of the present utility model is that part adds the fluid-tight structure in liquid sealing pipe and liquid sealing pipe in the tower of return duct, return duct is connected with the top of liquid sealing pipe, lower liquid pipe is connected by the middle and upper part of distributing pipe with fluid-tight structure, the bottom of distributing pipe is higher than the top of return duct, such structure ensure that return duct is full of liquid all the time, also be the key thoroughly getting rid of hammering generation, eliminate in return duct the situation having gas-liquid to coexist, completely avoid because high temperature gas enters return duct and occur the possibility of " hammering " phenomenon.Reflux structure is simple, and design is unique, embodies simple and practical feature.
Accompanying drawing explanation

Fig. 2 be in Fig. 1 A-A to schematic diagram;
Fig. 3 be in Fig. 1 B-B to schematic diagram.
Detailed description of the invention
Embodiment 1
A kind of rectifier column reflux device described by the present embodiment 1, as shown in Figure 1, Figure 2 and Figure 3, comprise the return duct 1 of the tower top being installed on rectifying column 5, return duct branch is connected with symmetry and disjunct liquid sealing pipe 4, the top of liquid sealing pipe is connected with return duct, the middle and upper part of liquid sealing pipe is connected with lower liquid pipe 2 by distributing pipe 3, and the bottom of distributing pipe is higher than the top of return duct.Fluid-tight structure is provided with in this liquid sealing pipe.All the time be filled with liquid in this return duct, ensure that return duct is full of liquid all the time, thus entirely eliminated in return duct the possibility that hammering occurs.
This reflux carries out designing for the backflow of large-scale rectifying column, so be designed with four tremie pipes, for small-sized rectifying column, can be reduced to two tremie pipes or even a tremie pipe, but must have fluid-tight structure.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to structure of the present utility model.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
Claims (3)
