Description
Technical field
Technical field of chemical is the utility model is related to, especially a kind of rectifying column.
Background technology
Rectifying column is a kind of tower vapor-liquid contacting apparatus for carrying out rectifying.The basic principle of distillation is that liquid mixture is more
Second part gasifies and partial condensation, using the different characteristic of wherein each component volatility, realizes the unit operation for separating purpose.
And existing rectifying column complicated integral structure, and tower body easily corrodes in use, so as to shorten the use of rectifying column
Service life；On the other hand, due to inevitably can there are different size of particle in steam so that different size of particle in gas into
Enter in tower body, get off for a long time, can cause to block inside tower body, so as to shorten the service life of rectifying column.
Utility model content
To be used in view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of simple in structure and extension
The rectifying column in service life.
What the technical solution of the utility model was realized in：A kind of rectifying column, including tower body, it is characterised in that：It is described
Overhead vapours outlet, reflux liquid pipe, tower tray, inlet tube, steam inlet and bottom of towe liquid are disposed with tower body from top to bottom
Outlet, the tower tray have multiple, and multiple tower tray arrangements intersected with each other, the tower body bottom is provided with skirt, is set on the skirt
It is equipped with skirt exhausting-gas hole；The inner wall of the tower body is provided with the corrosion-resistant coating made of graphite modified polypropylene material；The steaming
The filter assemblies for filtering gaseous impurity are provided with vapour entrance, the filter assemblies include circular frame and are arranged at circle
Multiple filtration net on frame, the circle frame are fixed on the inner wall of steam inlet, the mesh aperture of each layer filter screen by
Airintake direction is tapered into toward outgassing direction.
Preferably：The bottom of the skirt is provided with skirt foundation ring.
By using above-mentioned technical proposal, the utility model overall structure is simple, using tower body inner wall be provided with by
Corrosion-resistant coating made of graphite modified polypropylene material, ensure that tower body in use is less prone to corrosion phenomenon, so that
Extend the service life of rectifying column.Using in the upper filter assemblies being provided with for filtering gaseous impurity, pass through multiple filtration
It is effectively big to the difference in gas and the mesh aperture of each layer filter screen tapers into setting from airintake direction toward outgassing direction
Small impurity is gradually filtered, and is avoided the different size of impurity in gas from entering in tower body and is caused tower body blocking, so as to prolong
The service life of rectifying column is grown.
The utility model is further arranged to：Manhole is provided with the tower body.
By using above-mentioned technical proposal, manhole personnel easy to repair, which enter in tower body, carries out maintenance tower tray.
The utility model is further arranged to：Skirt manhole is provided with the skirt.
By using above-mentioned technical proposal, personnel easy to repair, which enter in skirt, to be carried out maintenance.
