Description
Technical field
The invention belongs to technical field of rectification, be specifically related to a kind of honeybee lattice packed tower.
Background technology
Packed tower is using the filler in tower as the mass transfer apparatus of contact member between gas-liquid two-phase, is widely used in the unit operations such as distillation, absorption, desorbing, extraction, stripping.For the packed tower of distillation procedure, in gas-to-liquid contact mass transfer, with the increase of tower diameter, owing to there is the phenomenons such as wall stream, channel, make the inhomogeneities that contacts with each other of gas-liquid two-phase increase, can seriously reduce separation efficiency.And adopt efficient packing of small particle and circular minor diameter tower (laboratory tower) that higher separation efficiency (every meter of 20～30 shelf theory plates) can be reached, but the disposal ability of packed tower is relevant with tower diameter, and therefore the disposal ability of minor diameter tower is limited.
In order to take into account separation efficiency and disposal ability, existing solution is multiple-tube column.Multiple-tube column is composed in parallel by the circular minor diameter tower of several filling high efficiency packings, but because its structure is complicated, making, installation and operation etc. require harshness to be only applicable to precise distillation.
Summary of the invention
For the deficiencies in the prior art, the technical problem that the present invention intends to solve is to provide a kind of honeybee lattice packed tower, and this packed tower has special internal structure, can ensure that when tower diameter expands, has the high separating efficiency identical with minor diameter tower.The attachment components such as the unit problem to solve to affect mass-transfer efficiency after tower height increases of liquid distribution, collection and redistribution is set simultaneously, the setting of this attachment component can guarantee that the uniform contact of gas-liquid two-phase, reduce the generation of the phenomenon such as wall stream and channel, disposal ability can be improved, all applicable from lab pilot plant to industrial mass production, the scope of application is wider.Tower height can be regulated by tower section superposition simultaneously, it is possible to meets different separation efficiency requirements.
It is an object of the invention to complete by following technical solution:
A kind of honeybee lattice packed tower, including outer tower body, it is characterized in that being provided with in described packed tower n tower section, n is natural number, tower in a number of hexagon all it is arranged in parallel along tower height direction in each tower section, being pressed into filler casting die and liquid re-distributor in each hexagon in tower upper port, lower port installs dismountable packing support；In a number of hexagon, tower is welded to each other together, constitutes lattice nest, and the sectional view of lattice nest is honeycomb, and the top edge of lattice nest is by shrouding and outer tower barrel soldering, and lower edge is by gripper shoe and outer tower barrel soldering.
Compared with prior art, the present invention adopts the lattice Nest architecture that in hexagon, tower is in parallel, both the problem that single column disposal ability and separation efficiency in prior art are low had been solved, notable shortening tower height degree simultaneously, have simple in construction, easy to process, material disposal ability is high, can effectively realize liquid in tower uniformly redistributes, improve the feature such as mass-transfer efficiency, operation variation, for all applicable from lab pilot plant to industrial mass production.
Analyzing structure, for tower, wall stream effect is relevant with the ratio k of wall girth and sectional area, and k value is more little, and wall stream effect is more weak.As, during with circular k value for 1, the k value of tetragon is 1.414, and hexagonal k value is 1.1547, and octagonal k value is 1.0823.With minor diameter tower and be unified in the cylinder that multitube is placed in a major diameter, wall stream effect is the most weak, but effective channel cross-sectional area utilization rate is low；If segmenting structure in the tower of major diameter, need again as far as possible little k value, as piled up by circle, cannot be closely coupled between each circle, there is gap, cause the segmentation difficulty connected with tower, for instance multiple-tube column is exactly very complicated in structure.Octagon k value is little, but its space availability ratio is low, similar with minor diameter tower effect；Hexagon k value is less and splitter simple in construction, channel cross-sectional area utilization rate are high, considers factors above, adopts hexagon better as segmenting structure separation efficiency and disposal ability.
