Description
Technical field
The utility model belongs to falling film evaporator technical field, specially a kind of falling film evaporator film-distributing device.
Background technology
Falling film evaporator film-distributing device at present, have the following disadvantages in use：
（1）Cloth film is uneven.
（2）Cloth film is unstable.
（3）Mounting means is complicated, it is difficult to ensures flatness.
Therefore, it is necessary to a kind of falling film evaporator film-distributing device of stabilization.
The content of the invention
The purpose of this utility model is to provide a kind of falling film evaporator film-distributing device, it is possible to achieve stable cloth film and peace
Dress is convenient.
The utility model is that the technical scheme used is realized：
A kind of falling film evaporator film-distributing device, including evaporator pipe sheet, heat exchanger tube is welded on the evaporator pipe sheet；Institute
Heat exchanger tube import welding distribution head is stated, the distribution head side offers some liquid inlet holes；It is distributed on the evaporator pipe sheet
There is distance sink tube, the distance sink tube installs distributing disc by nut, is evenly arranged on the distributing disc and is distributed disk liquid-inlet；Institute
State and be welded with riser on distributing disc with the correspondence position of heat exchanger tube, the riser lower end is stretched into distribution head, described liter of gas
Pipe lower end is provided with dovetail annular groove, and the dovetail annular groove is corresponding with the liquid inlet hole in distribution head；The riser upper side
Offer gas vent.
In use, liquid is flowed on tube sheet by the liquid-inlet on distributing disc, treat that the liquid level on tube sheet there was not distribution head
Liquid inlet hole after, into distribution head, liquid inlet hole in distribution head coordinates the dovetail groove structure of riser bottom to realize liquid
Film is evenly arranged, and gas is discharged by riser.In addition, it is connected using distance sink tube with distributing disc by nut, convenient disassembly
And it can guarantee that the levelness of distributing disc installation.
Preferably, some liquid inlet holes are tangentially provided with the distribution head, that is to say, that liquid inlet hole is not radially
It is opened in distribution head, and liquid inlet hole is inclined hole, such liquid changes after entering along heat transfer tube wall face uniform flow, rather than edge
Heat pipe inner wall is under plume, and it is uniform to be more beneficial for cloth film.
Film-distributing device described in the utility model is reasonable in design, has the characteristics of easy for installation, cloth film is uniform, stable.
Brief description of the drawings
Fig. 1 represents structural representation of the present utility model.
Fig. 2 represents the liquid inlet hole schematic diagram being tangentially distributed in distribution head.
In figure：1- heat exchanger tubes, 2- tube sheets, 3- distribution heads, 31- liquid inlet holes, 4- riseies, 41- dovetail annular grooves, 42- gas

Embodiment
In order that those skilled in the art are better understood from the utility model, the utility model is made below in conjunction with accompanying drawing into
One step understands, completely illustrated.
A kind of falling film evaporator film-distributing device, including distribution head 3, riser 4, distributing disc 5, distance sink tube 6 etc., specific knot
Structure is as shown in figure 1, weld heat exchanger tube 1 on evaporator pipe sheet 2；Distribution head 3, the side of distribution head 3 are welded in the import of heat exchanger tube 1
Face offers some liquid inlet holes 31, and further, liquid inlet hole is arranged to inclined hole（Tangentially）, and non-radial hole, such as Fig. 2 institutes
Show, it is uniform to be more beneficial for cloth film.
As shown in figure 1, distance sink tube 6 is distributed with the evaporator pipe sheet 2, the distance sink tube 6 is installed by nut to be distributed
Disk 5, it is connected using distance sink tube with distributing disc by nut, convenient disassembly and the levelness that can guarantee that distributing disc installation.Described point
It is evenly arranged on cloth disk 5 and is distributed disk liquid-inlet 51, liquid is flowed on tube sheet 2 by the import.
Riser 4 is welded with the distributing disc 5 with the correspondence position of heat exchanger tube 1, distribution is stretched into the lower end of riser 4
In first 3, the lower end of riser 4 is provided with dovetail annular groove 41, and the dovetail annular groove 41 and the liquid inlet hole 31 in distribution head 3 are right
Should, after liquid level did not had liquid inlet hole 31 on tube sheet 2, liquid enters from the liquid inlet hole 31, along it between dovetail annular groove 41
Gap flows down, afterwards along heat transfer tube wall face（In planar）Uniform flow.Liquid inlet hole in distribution head coordinates riser bottom
Dovetail groove structure, realize being evenly arranged for liquid film, the upper side of riser 4 offers gas vent 42, in liquid
Gas by riser by top gas export discharge.The distribution head of traditional film-distributing device is that end is zigzag, liquid edge
Heat exchanger tube is flowed between jagged groove, liquid most cases lower edge " strand " flows down from heat transfer tube wall, exist cloth film it is uneven,
The problem of unstable.And the utility model opens up liquid inlet hole in distribution head side（Inclined hole）, such liquid is equal along heat exchanger tube face
Cloth flows down so that cloth film is more uniformly, stably.
When it is implemented, distribution head 3 is connected as a single entity with heat exchanger tube 1 by welding, distance sink tube 6 passes through nut and distributing disc 5
Connection be can be very good to control distributing disc installation level and easy for installation, and some apertures are tangentially provided with distribution head 3 and are coordinated
The dovetail configuration of riser bottom realizes being evenly arranged for liquid film, and H1 is determined according to the evaporation capacity of downward film evaporator and liquid inlet volume
The number of openings of liquid inlet hole on~H4 reasonable size and distribution head.
The scope of the requires of the utility model protection is not limited to above embodiment, for those skilled in the art
Speech, the utility model can have a various deformation and change, it is all made within design of the present utility model with principle any repair
Change, improve and equivalent substitution all should be included in the scope of protection of the utility model within.
