It is that steam is entered by tower bottom, the liquid phase of the gas phase evaporated and tower top decline carries out counter current contacting, and two when being in contact, and makes liquid phase
In low boiling material be transferred in gas phase, and the high boiler material in gas phase is transferred in liquid phase, to realize the mesh of separation
's.Liquid distribution trough is provided in some rectifying columns, the effect of liquid distribution trough is the liquid-phase collection that will be left along inner wall of tower
And redistribute to middle part in tower, allow liquid and gas preferably to carry out haptoreaction.But existing liquid distribution trough is welding
It is fixed on inner wall of tower, so being unfavorable for repair and replacement.In order to solve this problem, application No. is CN201721045808.7's
Utility model discloses a kind of rectifying column of conveniently replaced liquid distribution trough, including tower body, tower reactor and liquid distribution trough；It is described
The bottom in the tower body is arranged in tower reactor；The tower body inner wall is provided with the accommodating cavity outwardly protruded, opposite in the tower body
The side of the accommodating cavity offers insert port；The liquid distribution trough side is provided with insertion section, and the other side is provided with sealing
Portion；When the liquid distribution trough is inserted into the tower body, the insertion section is contacted in the accommodating cavity, and the mouth-sealed portion contacts
Outside the insert port, in the utility model specification, more detailed description is carried out to distributor, has passed through its specification
Explanation it is found that the utility model structure is complicated, and due to use plug-in type distributor, influence the structural strength and sealing of tower body
There is high-risk gas risk of leakage in performance；In addition, the utility model is also without solving to flow down when liquid along packing layer
When, it may appear that wall flow phenomenon causes vehicle repair major to be unevenly distributed in packing layer, to make under separative efficiency
The problem of drop.
Utility model content
The problems solved by the utility model are overcome the deficiencies in the prior art places, and it is simple to provide a kind of structure
It to be easy for installation and removal, and can guarantee the structural strength and sealing performance of tower body, wall flow phenomenon can also be avoided, improve rectifying
A kind of detachable distributor of suspension type for rectifying column of tower separative efficiency.
The technical solution adopted in the utility model includes distribution grid, and multiple distributions are evenly distributed on the distribution grid
Hole is also welded with riser and central tube on the distribution grid, and central tube is equipped with overflow hole, in the outer circle of the distribution grid
It is welded with cylinder-shaped retaining ring, vertical center web is welded on the outer wall of cylinder-shaped retaining ring, passes through bolt on vertical center web
Horizontal connecting plate is connected with nut.
4 riseies are welded on the distribution grid.
4 overflow holes are equipped at the upward 30mm in upper surface on the central tube away from distribution grid.
Compared with prior art, the utility model has the beneficial effects that
(1) the utility model is evenly distributed with multiple distribution holes on distribution grid, and riser is also welded on distribution grid
And central tube, central tube are equipped with overflow hole, are welded with cylinder-shaped retaining ring in the outer circle of distribution grid, and the utility model is made to have product
Liquid, liquid separation and the effect for dividing gas, make uniform gas-liquid distribution, avoid and wall flow phenomenon occur, improve distillation efficiency.
(2) the utility model is uniformly distributed on the outer wall of cylinder-shaped retaining ring is welded with 3 vertical center webs and 3 levels
The connection of the utility model and tower body can be realized in use, horizontal connecting plate is welded on the inner wall of tower body in connecting plate,
The suspension type distributor in tower is constituted, not only can be convenient installation and removal, but also can guarantee the structural strength and sealing performance of tower body,
When disassembly, screw bolt and nut only need to be unloaded, can be taken out from tower body by vertical center web by distributor is whole, facilitate distributor
Replacement and cleaning distributor, structure is simple, especially suitable for the lesser tower of diameter.

Specific embodiment
As shown in Figure 1, Figure 2 and Figure 4, the technical solution adopted in the utility model includes distribution grid 1, in the distribution grid 1
On be evenly distributed with multiple distribution holes 2, and the distribution hole 2 on distribution grid 1 at triangular arrangement, on the distribution grid 1
It is welded with 4 riseies 3 and central tube 4,4 is uniformly distributed at the upward 30mm in upper surface away from distribution grid 1 on central tube 4 and overflows
Discharge orifice 5 is welded with cylinder-shaped retaining ring 6 in the outer circle of the distribution grid 1, is uniformly distributed welding on the outer wall of cylinder-shaped retaining ring 6
Have 3 vertical center webs 7, be connected with horizontal connecting plate 10 on each vertical center web 7, i.e., the vertical center web 7 with
It is corresponding on horizontal connecting plate 10 to be machined with bolt hole and pass through bolt 11 and nut 12 for vertical center web 7 and horizontal connecting plate 10
Connection.
As shown in Figure 3 and Figure 4, in use, horizontal connecting plate 10 is welded on the inner wall of tower body 9, this reality can be realized
It with novel and tower body 9 connection, is connect by upper flange 16 with upper section tower body, is connect by lower flange 8 with lower section tower body, worked
When, liquid through inlet tube 13 enter tower body 9 after fall into central tube 4, when hydrops reach and be more than overflow hole 5 height after pass through
Overflow hole 5 overflows into cylinder-shaped retaining ring 6, uniform liquid separation and transports downwards under the action of multiple distribution holes 2 on distribution grid 1
It is dynamic to enter liquid phase and gas phase mixing chamber 14, it is contacted with the gas entered from 15 bottom of filler chamber, makes uniform gas-liquid distribution, wherein gas
Body is moved upwards through riser 3 again, gas when moving upwards, because bleed around with liquid formed contact, thus make liquid with
The realization of both gas comes into full contact with, and avoids wall flow phenomenon, improves distillation efficiency；When disassembly, 11 He of bolt need to be only unloaded
Nut 12 can be taken out from tower body 9 by vertical center web 7 by distributor is whole, and the replacement and cleaning distribution of distributor are facilitated
Device, especially suitable for the lesser tower of diameter.
