Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail with specific embodiment, but not as the limit to the present invention
It is fixed.
Inventor has found during numerically modeling is carried out to centrifuge evaporimeter of the prior art, to evaporimeter inside
Baffle plate structure be optimized can in the case where ensureing that crushing not increase, it is further reduce in cold media gas containing liquid
Amount.Therefore, mainly consider at 3 points in the design of liquid barrier in the present invention：Filter effect, the liquid level surface pressing uniformity and
Total crushing, and an equalization point is found on this 3 points.
Fig. 5 to Figure 14 is refer to, the liquid barrier of the evaporimeter in the present invention includes plate body, wherein, it is formed with plate body
One or more are used to increase the surface area of the plate body and the groove 1 of water conservancy diversion.For example, in a preferred embodiment, this
The section of the groove 1 in bright can certainly may also be employed the section of other shapes with V-shaped or arc, as long as can reach above-mentioned
Purpose.It is highly preferred that multiple grooves 1 be arrangeding in parallel are formed with plate body, axis direction of these grooves 1 along plate body
Extend the length range of whole plate body.
Because the present invention increased groove 1 on the plate body of liquid barrier, therefore can ensure that overall dimensions are constant and do not increase
Plus in the case of unit crushing, increase the surface area of liquid barrier, to filter droplet to greatest extent, so as to further improve suction
The impact that gas carrying liquid is brought.
During work, the gas from vapor-liquid separation device assembly 5 out still contains some drop, and this partial drop is in gas
Because the effect of inertia can be impacted on liquid barrier 2 and other walls in steering procedure, liquid barrier 2 can make to lead to again after gas turns
Outlet tube assembly 4 is crossed, so as to play a part of filtration.
In the process, every one groove 1 in the present invention can play the guide functions of drop, with along with groove 1
Droplet flow resistance it is little, drop is gathered together, and makes drop larger, its be raised air-flow entrainment probability it is relatively also less,
After drop can be made to flock together along single fixed-direction, then drip (such as the arrow institute in Fig. 7 and Figure 11 with gravity direction
Show), reduce by the probability of reentrainment in drop dropping process, therefore improve filter effect, it is ensured that unit crushing is not
In the case of increase, infringement of the absorbing gas belt liquid to compressor is reduced, improve compression efficiency.
It is highly preferred that the groove 1 in the present invention is formed in the upper surface of plate body, and groove 1 is faced out by the following table of plate body
It is prominent, so, can simultaneously increase the surface area of the upper and lower both sides of plate body.Obviously, groove is only formed on an upper, and lower surface is
The form of shiny surface, falls within protection scope of the present invention.
Preferably, the first end of plate body is open architecture or enclosed construction, and second end (i.e. outlet end) of plate body is to open
Put structure.During installation, the first end of plate body towards the housing 3 of evaporimeter one end, when its end plate contact with housing 3, can
To adopt open architecture, and when it also has an intersegmental gap as shown in figs. 5 and 9 between housing 3, then can adopt closed
Structure.Preferably, groove 1 extends to the second end by the first end of plate body, through the whole length scope of plate body.
The cross sectional shape of the plate body in the present invention can be diversified, for example, in the embodiment shown in Fig. 5 to Fig. 8
In, the section of plate body is in circular arc generally；In the embodiment shown in Fig. 9 to Figure 12, the section of plate body takes the shape of the letter U, wherein,
The bottom of the U-shaped is horizontal, and both sides are skewed in what is expanded outwardly.
Further, it is of the invention with plate body of the prior art when Figure 13 and Figure 14 respectively illustrate arc and U-shaped section
Between surface area comparison diagram.In Figure 13 and Figure 14, shown in dotted line is the shape of plate body of the prior art, shown in solid
Be plate body in the present invention shape, can be clearly observed from figure, at the position in region 7, surface area is obtained
Significantly increase, therefore increase circulation area, so as to also reduce crushing to a certain extent, further, the circulation of increase
Size depends on groove type and number.
Due to present invention improves absorbing gas belt liquid phenomenon, therefore alleviate " liquid hammer " is produced to blade, slow down to blade
Corrosion, so as to avoid potential safety hazard.
Fig. 5, Fig. 6, Fig. 9 and Figure 10 are refer to, present invention also offers a kind of evaporimeter, including above-mentioned liquid barrier 2.
In this embodiment, evaporimeter includes housing 3, and liquid barrier 2 is preferably arranged on being slightly slanted with the axis of relatively described housing 3
The lower section of the outlet tube assembly 4 in housing 3 and positioned at housing 3, so, every one groove structure of liquid barrier can be played leads
Stream is acted on, and allows drop to flock together along incline direction, is more easy to be dripped with gravity direction, and makes droplet size larger, its
It is lower by the probability for rolling up suction entrainment by refrigerant air-flow in liquid barrier dropping process.It is highly preferred that liquid barrier 2 and the housing 3
Axis between included angle A be less than or equal to 5 degree.
Preferably, the first end of liquid barrier 2 is abutted or separated with the end plate of housing 3.
Preferably, evaporimeter also includes vapor-liquid separation device assembly 5, is arranged on the lower section of liquid barrier 2.
Present invention also offers a kind of refrigerating plant, including above-mentioned evaporimeter.Due to the gear of the evaporimeter in the present invention
Groove structure is employed on liquid plate 2 and is obliquely arranged, therefore the drop in flooded evaporator can be made easily to assemble, easily drip,
In the case of can not increasing crushing is ensured, further improve the absorbing gas belt liquid measure of unit.
Certainly, it is more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art
For, on the premise of without departing from its general principles, some improvements and modifications can also be made, these improvements and modifications
It is considered as protection scope of the present invention.
