Problems solved by technology

[0005] In order to make up for the deficiencies in the prior art, the present invention proposes a plate type fractionation tower. The present invention is mainly used to solve the problem that the valve plate is mostly made of metal. The rust phenomenon makes the valve plate easy to get stuck; at the same time, the valve plate is driven by high-pressure hot steam, and due to the poor tensile performance of the metal valve plate, it is easy to break the engaging part of the valve plate in the long-term rusted state Phenomenon, which in turn causes the valve plate to fall off, affecting the normal use of the tray

Abstract

The invention belongs to the technical field of fractionation towers, in particular to a plate type fractionation tower. The plate type fractionation tower comprises a tower body and tower plates, wherein the tower plates are evenly installed inside the tower body; an overflow weir is installed on the upper surface of each tower plate, and the side surface of the overflow weir is provided with a downflow spout; downflow spouts between two adjacent tower plates are arranged in a staggered way; elastic hat-like rings are inserted and arranged in the overflow holes, and the bottom ends of the elastic hat-like rings are provided with annular roll rims; the elastic hat-like rings are made of a fiberglass material; hat-like valve blocks are arranged above the overflow holes, made of the fiberglass material, and arranged on and connected with the elastic hat-like rings through elastic fiber ribbons; and the bottom ends of the elastic fiber ribbons are provided with roll rim clamping balls which are clamped in the annular roll rims. The plate type fractionation tower of the invention effectively prevents the phenomenon of wearing or rusting obstruction of the hat-like valve blocks caused by wearing or rusting of the hat-like valve blocks during long-term usage.

Description

technical field [0001] The invention belongs to the technical field of fractionation towers, in particular to a plate type fractionation tower. Background technique [0002] Fractionation is a common method for separating liquid mixtures by utilizing the difference in boiling point of liquid mixtures. This method is widely used in petroleum refining processes to separate various oil products. The plate fractionation tower is a common separation device in petrochemical enterprises, including the fractionation tower cylinder and the staggered trays in the cylinder. [0003] Existing fractionation trays consist of sieve plates and downcomers. The mixed liquid to be separated is heated to boiling, and part of the liquid becomes gas, and the gas rises in the holes of the sieve plate to the upper part of the fractionation tray. Due to the lower temperature in the upper part of the fractionation tower, part of the gas condenses into liquid, and the liquid falls with the drop. Tub...
