Detailed Description
The technical solution adopted by the present invention will be further explained below with reference to the accompanying drawings and embodiments to help those skilled in the art better understand the technical solution of the present invention.
Example 1
In the present embodiment, all the members are made of a plate material having an equal thickness.
As shown in fig. 1-4, for an embodiment of the vortex-proof distributor for an extraction tower in the present invention, the distributor includes a distribution plate 1, a circular down-flow barrel 2 and a cross-shaped vortex-proof plate 3.
The distribution plate 1 is integrally formed by punching, the width of the bottom surface of the distribution plate is 320-400mm, the two end surfaces of the distribution plate form arcs and are equidistant to the inner surface of the tower body, the bottom surface is provided with sieve holes, the diameters of the sieve holes are 1-4mm, the sieve holes are uniformly distributed according to the square shape, the distance between the sieve holes is 15-40mm, two side surfaces are provided with supporting beams, the height of each supporting beam is 80-140mm, the upper parts of the supporting beams on two sides are provided with bending parts, the width of each bending part is 20-60mm, the supporting beams on two sides are provided with two rows of connecting round holes.
The diameter of the inner through hole of the circular liquid descending cylinder 2 is 30-60mm, the height of the circular liquid descending cylinder is 100-160mm, the circular liquid descending cylinders are mutually staggered, are in a staggered structure and are welded on the bottom surface of the distribution disc 1, the number of the circular liquid descending cylinders is 10-20, and the circular liquid descending cylinders are determined according to the liquid quantity requirement of the distributor.
The cross-shaped vortex-preventing plate 3 is formed by welding three rectangular plates with equal height, the height is 20-50mm, one rectangular plate is 50-80mm, the other two rectangular plates are 20-60mm, the cross-shaped vortex-preventing plates are welded on the upper part of the circular liquid dropping cylinder 2, and the number of the cross-shaped vortex-preventing plates is the same as that of the circular liquid dropping cylinder.
