Abstract
The utility model discloses an anhydrous hydrogen fluoride rectifying tower which comprises a tower body, a tower kettle and a reboiler, wherein the tower kettle is arranged at the bottom of the tower body and is directly communicated with the inner part of the tower body, and the top and the bottom of the reboiler are respectively communicated with the side surface of the tower body and the bottom of the tower kettle by a pipeline. In the anhydrous hydrogen fluoride rectifying tower, the bottom of the tower body is directly communicated with the tower kettle so that a complicated three-way pipeline is saved, and the occupied areas of the tower body and the tower kettle are reduced; and the reboiler is directly communicated with the tower body and the tower kettle so that the length of the used pipeline is reduced, heat losses are reduced, and production energy consumption is lowered.
Description
Technical field
The utility model relates to a kind of anhydrous hydrogen fluoride rectifying tower.
Background technology
Traditional anhydrous hydrogen fluoride rectifying tower, comprise tower body, tower still and reboiler, tower still and reboiler are located at the side of tower body, the top of tower still is connected with the top of tower body side and reboiler respectively by three-way pipeline and communicates, the bottom of tower still is connected with the bottom of the bottom of tower body and reboiler respectively by three-way pipeline and communicates, be communicated with liquidometer on the three-way pipeline of tower still and tower still bottom, the side of tower body also is provided with temperature-measuring port, and the top of tower body also is provided with condenser.Adopt the anhydrous hydrogen fluoride rectifying tower of said structure, tower body and tower still floor space are big, and connecting tube is many, and these connecting tubes have not only reduced the material transmission efficiency, also can cause scattering and disappearing of heat, cause unnecessary waste; In addition, the liquidometer end opening is connected on the three-way pipeline of tower still bottom, because the deposition of the impurity in the still liquid in the tower still causes the liquidometer end opening to stop up easily, causes the liquid level of liquidometer to show inaccurate.
The utility model content
The purpose of this utility model provides that a kind of floor space is little, good integrity, anhydrous hydrogen fluoride rectifying tower that connecting tube is few.
In order to realize above purpose, the technical scheme that the utility model adopted is: a kind of anhydrous hydrogen fluoride rectifying tower, comprise tower body, tower still and reboiler, described tower still be located at the bottom of tower body and directly with the tower body internal communication, the top of described reboiler and bottom are connected bottom pipeline and tower body side and tower still respectively and communicate.
The side of described tower body and tower still is provided with liquidometer.
Described tower still is coaxial setting up and down with tower body.
Anhydrous hydrogen fluoride rectifying tower of the present utility model, the tower body bottom directly is communicated with the tower still, has saved lengthy and tedious three-way pipeline, and has reduced the floor space of tower body and tower still; Reboiler directly is communicated with tower body and tower still, has reduced the length of used pipeline, has reduced scattering and disappearing of heat, has reduced the energy consumption of producing.In addition, the liquidometer end opening of the utility model rectifying tower is positioned at the side of tower still, and liquidometer adopts this structure setting, avoids the influence of still liquid deposition impurity in the tower still, and the liquid level that has solved liquidometer shows inaccurate problem.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model anhydrous hydrogen fluoride rectifying tower.
Embodiment
A kind of specific embodiment of anhydrous hydrogen fluoride rectifying tower of the present utility model as shown in Figure 1, comprise tower body 11, tower still 13 and reboiler 14, described tower still 13 is located at bottom and direct and tower body 11 internal communication of tower body 11, the top of reboiler 14 is connected with tower body 11 sides by pipeline 17 and communicates, and the bottom is connected with tower still 13 bottoms by pipeline 18 and communicates; Be provided with liquidometer 12 in the connection of the side of tower body 11 and tower still, the side of tower body 11 also is provided with temperature-measuring port 20, also is provided with condenser 19 at the top of tower body 11.
Embodiment of the present utility model is the non-limiting the technical solution of the utility model in order to explanation only; wherein in specific embodiment; tower body is directly arranged on the tower still; tower body adopts coaxial setting with the tower still; also can adopt other non-coaxial manner setting; the technical scheme that every employing tower still is located at the tower body bottom and directly is communicated with tower body all should fall into protection domain of the present utility model.
Claims (3)
