Description
Technical field
The utility model relates to a kind of alternating expression sieve plate installing structures of circulation pattern sieve-plate tower, belong to air separation unit skill
Art field.
Background technique
Circulation pattern sieve-plate tower is widely used in air separation unit, compares other sieve-plate towers, more efficient, load regulation range is more
It greatly, is the highest sieve-plate tower of cost performance in everyways such as energy consumption, economy, as shown in Figure 1.But the presence for the error that throttles is led
The uncertainty for causing column plate orientation, not only greatly reduces the economy of tower and its peripheral equipment, more constrains circulation type tower plate
Technology is in large-scale, super-huge space division field, the development for aspects such as process complexity, more, the rectifying purity requirement height of material mouth.
The researcher for being dedicated to research throttling error problem in rectifying column field in the world is more, their final a part are locked to adopt
The size of throttling error is determined with the method for manufacture actual measurement, and temporarily determines that nozzle orientation carries out pipe arrangement by this, it is another
Influence of the part to develop or eliminate using the sieve plate of other structures the method for circulation pattern sieve plate to solve the problems, such as throttling error,
Both methods is time-consuming and laborious, costly, or even has abandoned the essence of circulation pattern sieve plate, it is clear that has all avoided circulation pattern sieve plate section
Stream error problem.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and it is simple to provide a kind of structure, installation side
Just, the rectification effect of circulation pattern splitter column can be greatly improved, to reduce the energy consumption of tower and peripheral equipment, saves production cost
The alternating expression sieve plate installing structure of circulation pattern sieve-plate tower.
The purpose of this utility model is completed by following technical solution, a kind of alternating expression sieve of circulation pattern sieve-plate tower
Board mounting structure, it includes tower body, is equipped with muti-piece circulation sieve plate up and down in tower body, the circulation sieve plate includes up time needle ring
Two kinds of sieve plate and circulation sieve plate counterclockwise are flowed, and the sieve plate flow direction of the adjacent installation of interlayer up and down is completely on the contrary, i.e. one of
For circulation sieve plate clockwise, adjacent another piece is circulation sieve plate counterclockwise.
As preferred: being provided with column plate on the circulation sieve plate and connect liquid bath, connect an avris phase of liquid bath in the column plate
Neighbour is provided with column plate downspout, and liquid circulation direction is flowed on the outside of downspout on the outside of liquid bath one and enters downspout from connecing；It is described
Downspout alignment lower layer's circulation sieve plate of upper ocean heat content sieve plate connects liquid bath, and the upper ocean heat content sieve plate connects liquid bath against lower layer
The downspout of circulation sieve plate.
The utility model mainly utilizes circulation pattern sieve-plate structure feature, liquid flow mass transfer effect linear change and
The accumulative rule of installation error, the method by carrying out positive and negative alternate combination to circulation pattern sieve plate change liquid air flowing law, eliminate
The concentration difference of gas makes to establish on sieve plate and the adjacent the most similar gas-liquid contact mass transfer condition of one layer of sieve plate, efficiency of sieve plate hair
It waves suitable with adjacent one layer of sieve plate, and then reduces or eliminates throttling error, improve rectification efficiency；Simple, the installation side with structure
Just, the rectification effect of circulation pattern splitter column can be greatly improved, to reduce the energy consumption of tower and peripheral equipment, saves production cost etc.
Feature.

Fig. 1 is conventional circulation pattern sieve-plate tower mounting structure schematic diagram.
Fig. 2 is circulation pattern sieve-plate tower mounting structure schematic diagram described in the utility model.
Fig. 3 is the sieve-plate structure schematic diagram of one layer of the utility model installation.
Fig. 4 is the sieve-plate structure schematic diagram of the utility model adjacent layer installation.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: shown in Fig. 2-4, a kind of friendship of circulation pattern sieve-plate tower
Wrong formula sieve plate installing structure, it includes tower body 1, is equipped with muti-piece circulation sieve plate 2 in tower body 1 up and down, the circulation sieve plate 2 wraps
Include two kinds of circulation sieve plate (shown in Fig. 4) clockwise and circulation sieve plate counterclockwise (shown in Fig. 3), and the adjacent installation of interlayer up and down
For sieve plate flow direction completely on the contrary, i.e. one of is circulation sieve plate clockwise, adjacent another piece is circulation sieve plate counterclockwise.
As shown in the figure, column plate is provided on the circulation sieve plate 2 and connects liquid bath 3, connect an avris of liquid bath 3 in the column plate
Column plate downspout 4 has been disposed adjacent it, liquid circulation direction flows to 4 outside of downspout and enters downspout from connecing 3 one outside of liquid bath
4；The alignment lower layer's circulation sieve plate of downspout 4 of the upper ocean heat content sieve plate connects liquid bath 3, and the upper ocean heat content sieve plate connects liquid bath
3 against lower layer's circulation sieve plate downspout 4.
Embodiment: the utility model is in circulation pattern sieve-plate tower design basis, by kth layer sieve plate and+1 layer of kth of sieve plate
Backflow direction design is on the contrary, connect the alternately variation of liquid bath and downspout design position.
During the installation process, the downspout position for connecing liquid bath and being directed at+1 layer of kth for guaranteeing kth layer column plate, guarantees splitter column
In to connect top view setting angle position in liquid bath and downspout vertical direction almost the same, reduce assembling deviation.
Alternating expression circulation sieve plate splitter column described in the utility model, so that interior circulating liquid flows to positive and negative alternate flowing,
It can be well solved and restricted brought by throttling error.It is verified by product testing, novel alternating expression circulation tower compares other shapes
Formula splitter column rectification efficiency is higher, entirely reaches 90% or more, even up to 112%.This is multiple to the enlargement of space division tower and process
Hydridization and it is energy-saving, reduce cost etc. and play a significant role.
