Abstract
A vacuum demister relates to a device for removing foams in air flow from a reboiler in sulfolane production equipment. At present, foams, which are generated during heating and vaporization process of a material by a reboiler, enter into a rectifying tower with the air flow, thus influencing the separation effect of sulfolane in the rectifying tower. The vacuum demister provided by the invention is mainly designed to solve the above problem. The vacuum demister contains a cylindrical shell. The bottom of the cylindrical shell is provided with an air intake for connecting with the reboiler. A filling material support is arranged over the air intake. A filling material is filled over the filling material support. The upper portion and the lower portion of the cylindrical shell are respectively provided with hand holes for filling and replacing the filling material. The top of the cylindrical shell is provided with a gas outlet for connecting with the rectifying tower. The invention has the following advantage: after the foams in the vaporized gas are absorbed by the filling material, the filing material enters into the rectifying tower, so as to raise the separation effect of sulfolane in the rectifying tower.
Description
Technical field:
The present invention relates to the device that a kind of foam of producing in the air-flow that ability will be come out in the sulfolane equipment is removed from reboiler.
Background technology:
At present, directly be connected by connecting pipe between sulfolane rectifying column and the reboiler, when reboiler adds the thermal material vaporization, can produce more foam, foam gets in the rectifying column with air-flow, influence the separating effect of the interior sulfolane of rectifying column.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of being contained in and be connected the vacuum demister that the foam in the air-flow that the ability on the pipeline will come out is removed between reboiler and the rectifying column from reboiler.
Above-mentioned purpose is achieved in that it comprises cylindrical shell; The air inlet that the cylindrical shell bottom has confession to be connected with reboiler; The air inlet top has filler to support, and filler supports the top charge, and the foam in the boil-off gas is absorbed the back by filler and gets into rectifying column; Be respectively equipped with the hand hole that installs and change filler additional in the upper and lower of cylindrical shell, the gas outlet that the cylindrical shell top has confession to be connected with rectifying column.
Advantage of the present invention is, after reboiler added boil-off gas that thermal material produces and gets in the tube by the air inlet of cylindrical shell bottom, the foam in the boil-off gas was absorbed the back by filler and gets into rectifying column, improves the sulfolane separating effect in the rectifying column.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
With reference to accompanying drawing; It comprises cylindrical shell 1; The air inlet 2 that the cylindrical shell bottom has confession to be connected with reboiler, the air inlet top has filler to support 3, and filler supports top charge 4; Be respectively equipped with the hand hole 5 that installs and change filler additional in the upper and lower of cylindrical shell, the gas outlet 6 that the cylindrical shell top has confession to be connected with rectifying column.
