Description
本发明涉及制冷领域,尤其涉及一种均流板、油分离器、冷凝器及闪发器。The invention relates to the field of refrigeration, and in particular to a flow equalization plate, an oil separator, a condenser and a flasher.
空调制冷系统中,压力容器是主要元件,如蒸发器、冷凝器、油分离器、闪发器等,它们在整个系统中空间占比较大。随着用户需求多种多样,市场面向于体积小、性能高的方向集中。这也是技术与结构理念的兼顾发展,进而内置油分离器发展迅速,出现了各种新结构、新形式。但是,内置油分离器的研究重点不仅仅是节省机组空间,其分离效果的机理分析也是重中之重。在总体积不变、功耗不变的内置油分离器中,内部件结构形式决定着油气分离的能力,甚至结构优化后,其占用空间也会随之减小。内置油分离器中气流流动状态及过程较复杂,具体的规律很难找寻。In air conditioning refrigeration systems, pressure vessels are the main components, such as evaporators, condensers, oil separators, flashers, etc., which occupy a large space throughout the system. With a variety of user needs, the market is focused on small size and high performance. This is also the development of both technical and structural concepts, and the built-in oil separator has developed rapidly, and various new structures and forms have emerged. However, the research focus of the built-in oil separator is not only to save the unit space, but also the mechanism analysis of the separation effect. In the built-in oil separator with the same total volume and constant power consumption, the internal component structure determines the ability to separate oil and gas. Even after the structure is optimized, the occupied space will be reduced. The flow state and process of the airflow in the built-in oil separator are complicated, and the specific laws are difficult to find.
发明内容Summary of the invention
现有的内置油分离器通常设置于冷凝器内部中上方,为了协调冷凝管有效布置,其内置油分离器的截面形状受限。进而导致其内部元件设计在符合汽液分离机理的同时,做出适当的调整,以拟合内置油分离器外形结构形式。而在汽液分离器分离效果在结构确定的情况下,流场状态对分离效果影响最大。The existing built-in oil separator is usually disposed above the inside of the condenser, and the cross-sectional shape of the built-in oil separator is limited in order to coordinate the effective arrangement of the condensing duct. In turn, the internal component design is adapted to the vapor-liquid separation mechanism, and the appropriate adjustment is made to fit the internal oil separator shape structure. However, in the case where the separation effect of the vapor-liquid separator is determined in the structure, the flow field state has the greatest influence on the separation effect.
发明人经过研究发现,均流板的合理设计对分离效果有重要影响,具体来说,现有的均流板除了起到均气效果之外,在油气混合物经过均流板后撞击滤网后,气体穿过滤网进入到冷凝器,而油滴被阻隔在滤网下面,顺着重力作用向下滴落,透过均流板小孔回到积油槽 中。这个过程中,油滴回落的量对整个油分离器的分离效果起着至关重要的作用。但是,由于均流板中小孔周围气流源源不断,积累的油滴回程阻力较大,进而影响到油分离器的分离效果。The inventors have found through research that the rational design of the flow equalization plate has an important influence on the separation effect. Specifically, the existing current sharing plate not only plays the equal gas effect, but also hits the filter after the oil and gas mixture passes through the current equalizing plate. The gas enters the condenser through the filter, and the oil droplets are blocked under the filter screen, dripping down the gravity, and returning to the oil accumulation tank through the small holes of the flow equalization plate. In this process, the amount of oil droplets falling back plays a crucial role in the separation of the entire oil separator. However, due to the continuous flow of air around the small holes in the flow equalization plate, the accumulated oil droplet return resistance is large, which in turn affects the separation effect of the oil separator.
有鉴于此,本发明提出一种均流板、油分离器、冷凝器及闪发器,能够提高气态介质和液态介质的分离效果。In view of this, the present invention provides a current equalizing plate, an oil separator, a condenser, and a flasher, which can improve the separation effect of a gaseous medium and a liquid medium.

下面通过附图和实施例,对本发明的技术方案做进一步的详细描述。The technical solution of the present invention will be further described in detail below through the accompanying drawings and embodiments.
如图1所示,为本发明均流板的一实施例的示意性结构图。在本 实施例中,均流板1包括板体11,在所述板体11的至少一个侧边上沿所述板体11的长度方向设置有多个过液槽12,以便所述板体11上方的沉积液滴通过所述过液槽12流回所述板体11下方。FIG. 1 is a schematic structural view of an embodiment of a current sharing plate of the present invention. In the present embodiment, the current equalizing plate 1 includes a plate body 11 on which a plurality of liquid passing grooves 12 are disposed along at least one side of the plate body 11 so that the plate body The deposited droplets above the 11 flow back through the overflow tank 12 back below the plate body 11.
在本实施例中,过液槽分布设置在板体的至少一个侧边上,均流板所连接的壁面与过液槽之间能够形成板体上方的沉积液滴的导流通道,沉积液滴可通过过液槽流向均流板的下方,并能够降低其他方向的流体对沉积液滴向下回流效果的影响,从而提高了均流板对气态介质和液态介质的分离效果。In this embodiment, the liquid distribution tank is disposed on at least one side of the plate body, and a flow guiding channel for depositing droplets above the plate body can be formed between the wall surface connected to the flow regulating plate and the liquid passing tank, and the deposition liquid The droplets can flow down the flow plate through the liquid flow tank, and can reduce the influence of fluids in other directions on the downward flow of the deposition droplets, thereby improving the separation effect of the flow plates on the gaseous medium and the liquid medium.
为了降低气液混合物的流速,并实现气液分离,可以进一步在所述板体11的两个侧边之间的板体11表面上分布设置多个均流孔13,以便气液混合物通过所述均流孔13从所述板体11下方到达所述板体11上方。对于均流孔13来说,气液混合的流体介质会从下通过均流孔13流向板体11的上方。而板体11上方的沉积液滴可以通过过液槽12流到板体11下方。这样就使得沉积液滴能够尽量避开均流孔13中向上流动的气液混合物,减少该气液混合物对沉积液滴向下回流效果的影响,从而提高了均流板对气态介质和液态介质的分离效果。In order to reduce the flow rate of the gas-liquid mixture and achieve gas-liquid separation, a plurality of equalizing holes 13 may be further distributed on the surface of the plate body 11 between the two side edges of the plate body 11 so that the gas-liquid mixture passes through The mean flow hole 13 reaches the upper side of the plate body 11 from below the plate body 11. For the equalizing holes 13, the gas-liquid mixed fluid medium flows from below through the equalizing holes 13 to the upper side of the plate body 11. The deposition droplets above the plate body 11 can flow through the liquid supply tank 12 to below the plate body 11. In this way, the deposited droplets can avoid the upward flow of the gas-liquid mixture in the flow-through hole 13 as much as possible, thereby reducing the influence of the gas-liquid mixture on the downward flow of the deposition droplets, thereby improving the flow medium and the liquid medium of the flow plate. The separation effect.
当将本实施例的均流板应用到油分离器时,均流板在分离油气混合物的同时,又承担着沉积油滴的作用。油气混合物在从下至上通过均流板时,速度能够得到重新分配。大部分油通过撞击分离作用会掉落至储油槽,但仍有一部分油随着气流穿过均流板后进入滤网,而后被阻拦在滤网中。当滤网中油滴积累量足够大,便会沿着滤网及油分离器侧壁面滴淋到均流板上表面,其中油分离器侧壁面的油滴可以沿着油分离器侧壁面与板体侧边上的过液槽之间形成的导流通道向下流动,而滴淋到均流板上表面的大油滴可以被向上的流体吹破,并溅到油分离器侧壁面上,再顺着侧壁面从过液槽向下流到积油槽中。这样,通过上述过液槽的设置,解决了均流孔以外的流动死区,提高了沉积液滴的回流效果,提升了积油槽的储油量,进而提高了油分离器的油气分离效果。When the current equalizing plate of the present embodiment is applied to the oil separator, the flow equalizing plate is responsible for depositing oil droplets while separating the oil and gas mixture. The velocity can be redistributed as the oil and gas mixture passes through the flow equalization plate from bottom to top. Most of the oil will fall to the sump by impact separation, but still a portion of the oil enters the screen as it passes through the flow plate and is then blocked in the screen. When the oil droplet accumulation in the filter screen is large enough, it will drip along the side wall of the filter screen and the oil separator to the surface of the flow equalizer. The oil droplets on the side wall of the oil separator can be along the side wall and plate of the oil separator. The flow guiding channel formed between the liquid passing tanks on the side of the body flows downward, and the large oil droplets dripping onto the surface of the flow equalizing plate can be blown by the upward fluid and splashed on the side wall surface of the oil separator. Then, along the side wall surface, it flows downward from the liquid tank to the oil accumulation tank. Thus, through the arrangement of the above-mentioned liquid passing tank, the flow dead zone outside the flow sharing hole is solved, the backflow effect of the deposited liquid droplets is improved, the oil storage amount of the oil accumulation tank is improved, and the oil and gas separation effect of the oil separator is improved.
在另一个实施例中,本发明的均流板1还可以应用于其他的气液 分离设备,涉及到的沉积液滴并不限于润滑油,还可以包括液态冷媒、燃油等。其他气液分离设备中均流板所实现的功能作用均可参考在油分离器中的功能作用,这里就不再一一赘述了。In another embodiment, the current equalizing plate 1 of the present invention can be applied to other gas-liquid separation devices, and the deposition droplets involved are not limited to lubricating oil, and may include liquid refrigerant, fuel oil, and the like. The functional functions realized by the flow plates in other gas-liquid separation devices can be referred to the functional functions in the oil separator, and will not be further described here.
如图2-图5所示,分别为本发明均流板的多个实施例的示意性局部结构图。均流板1的过液槽12在所述板体11的表面上可以呈多种开槽形状,包括弧形、多边形或弧形与多边形的组合。例如图5中示出的矩形过液槽、图4中示出的弧形过液槽(包括半圆形过液槽)、图3中示出的梯形过液槽、图2中示出的三角形过液槽等。在一个均流板1上,可以设置同一种开槽形状的过液槽12,也可以设置多种开槽形状的过液槽12。2 to 5 are schematic partial structural views respectively showing a plurality of embodiments of the flow equalizing plate of the present invention. The liquid-passing groove 12 of the flow equalizing plate 1 may have various grooved shapes on the surface of the plate body 11, including a curved shape, a polygonal shape, or a combination of a curved shape and a polygonal shape. For example, the rectangular over-tank shown in Figure 5, the curved over-tank shown in Figure 4 (including a semi-circular over-tank), the trapezoidal over-tank shown in Figure 3, shown in Figure 2 Triangle over tank and so on. On one of the equalizing plates 1, the same type of grooved over-liquid tank 12 may be provided, or a plurality of grooved over-liquid tanks 12 may be provided.
各种形状的过液槽的尺寸可以按照结构加工难度做出调整。针对于应用的气液分离设备(例如油分离器等)的容量高低、功耗能力,各种形式的过液槽的尺寸可随之改动。在进行不同形状的过液槽的选择时,如果主要考量因素在于加工难度和批量生产率等,则可以采用比较容易加工的矩形过液槽与弧形过液槽,这种形状的过液槽也适合于批量生产。如果主要考量因素在于回油能力,则可以采用回油能力更强的梯形过液槽和三角形过液槽等多边形过液槽的结构形式,此类过液槽具有棱角,能够对下落的液滴起到导流作用,从而回油能力更好。在实际设计时,可以在不同的要求下针对不同形状的过液槽进行实验分析,以确定最优结构。The size of the various shapes of the liquid tank can be adjusted according to the structural processing difficulty. The size of various types of over-fluid tanks can be changed depending on the capacity and power consumption of the gas-liquid separation equipment (such as oil separators) used in the application. When selecting the tanks of different shapes, if the main considerations are processing difficulty and mass productivity, etc., it is possible to use a rectangular over-fluid tank and an arc-shaped liquid tank which are relatively easy to process, and the over-tank tank of this shape is also Suitable for mass production. If the main consideration is the oil returning ability, a structural form of a polygonal over-fluid tank such as a trapezoidal liquid tank and a triangular liquid tank having a stronger oil returning ability can be used. Such an over-liquid tank has an angular shape and can be used for falling droplets. It acts as a diversion and thus has better oil returning ability. In the actual design, experimental analysis of different shapes of the liquid tank can be carried out under different requirements to determine the optimal structure.
过液槽12形成于板体11的上表面到下表面之间,与上下表面相接的槽壁的设置形式对回油效果也有一定影响。在本发明均流板的实施例中,过液槽12的槽壁可以相对于所述板体11的表面垂直(例如图2-图5中各种形状的过液槽121a、122a、123a和124a等),也可以相对于所述板体11的上侧表面呈预设外斜角α(例如图2-图5中各种形状的过液槽121b、122b、123b和124b等)。垂直或外斜形式的槽壁能够配合均流板所连接的壁面形成上大下小的导流通道结构,这种通道结构可以促进沉积液滴的向下流动。对于外斜形式的槽壁,针对预设外斜角可分为相对水平角度呈0°到45°,45°到90°两种情况。 从45°到0°的变化过程中,截面积变化较快,有利于减小气流阻力,但油滴受壁面摩擦阻力在增大。在45°到90°的变化过程中,截面积突变比率在变小,油滴受壁面摩擦阻力在减小。因此综合考虑,优选预设外斜角为30°~60°,更优选的预设外斜角为45°,从而兼顾到加工便利性以及气流阻力与回油均衡作用。The liquid passing tank 12 is formed between the upper surface and the lower surface of the plate body 11, and the arrangement form of the groove wall that is in contact with the upper and lower surfaces also has a certain influence on the oil returning effect. In the embodiment of the flow equalizing plate of the present invention, the groove wall of the liquid passing tank 12 may be perpendicular to the surface of the plate body 11 (for example, the liquid tanks 121a, 122a, 123a of various shapes in FIGS. 2 to 5 and 124a, etc., may also be provided with a predetermined outer oblique angle α with respect to the upper side surface of the plate body 11 (for example, the liquid overflow grooves 121b, 122b, 123b, and 124b of various shapes in FIGS. 2 to 5, etc.). The wall of the vertical or outer oblique form can form a large and small flow guiding channel structure with the wall surface connected to the flow equaling plate, and the channel structure can promote the downward flow of the deposition droplets. For the groove wall of the outer oblique form, the preset outer oblique angle can be divided into two cases of a relative horizontal angle of 0° to 45° and 45° to 90°. During the change from 45° to 0°, the cross-sectional area changes rapidly, which is beneficial to reduce the airflow resistance, but the oil droplets are increased by the wall frictional resistance. During the change from 45° to 90°, the cross-sectional area abrupt ratio becomes smaller, and the oil droplets are reduced by the wall frictional resistance. Therefore, in general consideration, it is preferable that the preset external oblique angle is 30° to 60°, and the more preferable preset external oblique angle is 45°, thereby achieving both processing convenience and airflow resistance and oil return equalization.
在板体11的厚度条件充足的情况下,可以在过液槽12的槽壁靠近所述板体11下侧的位置进一步设置过渡钝边结构(例如图2-图5中各种形状的过液槽121c、122c、123c和124c等)。过渡钝边结构是指在过液槽12的呈预设外斜角(例如45°)的槽壁的预设厚度位置(例如以板体11的下侧表面为基准的整体厚度的1/2或1/3等)上形成的倾角(例如60°或90°等,优选为90°)大于预设外斜角且小于等于90°的过渡部分。参考图2-图5,该过渡钝边结构使得过液槽12的槽壁在板体11的厚度方向形成了外斜角突变的效果,进而实现过液槽12的截面突变,而利用这种截面突变的效果能够减小油滴回落过程中受到的气流阻力。而为了提高生产效率,也可以选择不在呈外斜角的槽壁上留钝边的结构形式。In the case where the thickness of the plate body 11 is sufficient, a transitional blunt edge structure (for example, various shapes in FIGS. 2 to 5) may be further disposed at a position where the groove wall of the liquid supply tank 12 is adjacent to the lower side of the plate body 11. Liquid tanks 121c, 122c, 123c, and 124c, etc.). The transitional blunt edge structure refers to a predetermined thickness position of the groove wall of the over-fluid tank 12 at a predetermined outer oblique angle (for example, 45°) (for example, 1/2 of the overall thickness based on the lower surface of the plate body 11) The inclination angle formed on the 1/3 or the like) (for example, 60° or 90°, etc., preferably 90°) is greater than the transition portion of the preset outer oblique angle and less than or equal to 90°. Referring to FIG. 2 to FIG. 5, the transitional blunt edge structure causes the groove wall of the liquid tank 12 to form an external oblique angle mutation effect in the thickness direction of the plate body 11, thereby realizing the sudden change of the cross section of the liquid tank 12, and utilizing this The effect of the cross-section abrupt change can reduce the resistance of the airflow received during the drop of the oil droplets. In order to improve production efficiency, it is also possible to select a structure that does not leave a blunt edge on the groove wall of the outer bevel.
过液槽的结构和数量设计可以主要考虑相对气液分离设备的容量大小及均流孔总面积比率之间的关系。随着气液分离设备容量的增大,过液槽面积占比可适当的增加,优选单个的过液槽12的截面积大于300mm
2。但为保证均流孔的均气效果,通过过液槽12的气流总量不超过均流孔13的气流总量的1%。
The structure and quantity design of the liquid tank can mainly consider the relationship between the capacity of the gas-liquid separation device and the ratio of the total area of the flow holes. As the capacity of the gas-liquid separation device increases, the ratio of the area of the overflow tank can be appropriately increased. Preferably, the cross-sectional area of the single over-tank 12 is greater than 300 mm 2 . However, in order to ensure the equalization effect of the flow holes, the total amount of gas flowing through the liquid flow tank 12 does not exceed 1% of the total gas flow of the flow holes 13.
如图6所示,为本发明冷凝器的一实施例的示意性结构图。在本实施例的冷凝器中,包括了内置形式的油分离器A,以及冷凝器中的其他元器件,例如冷凝管B等。参考图7-图9所示的油分离器实施例,该油分离器A包括壳体、油气进口3和前述任一种均流板1的实施例。其中,图7中示出的油分离器A的壳体可由侧封板23、轴向端部封板8、回油侧封板9、中间封板4和顶部封板2等焊接形成,并避免泄漏。油气进口3可以设置在壳体沿长度方向的任意一端,例如图7所示的最左侧一端。FIG. 6 is a schematic structural view of an embodiment of a condenser of the present invention. In the condenser of the present embodiment, the oil separator A in the built-in form, and other components in the condenser, such as the condenser B and the like, are included. Referring to the oil separator embodiment shown in Figures 7-9, the oil separator A includes a housing, an oil and gas inlet 3, and an embodiment of any of the foregoing flow equalization plates 1. Wherein, the housing of the oil separator A shown in FIG. 7 may be formed by welding the side sealing plate 23, the axial end sealing plate 8, the oil return side sealing plate 9, the intermediate sealing plate 4, and the top sealing plate 2, and the like. Avoid leaks. The oil and gas inlet 3 may be disposed at either end of the housing along the length direction, such as the leftmost end shown in FIG.
另外,油分离器A还可以包括气液滤网6和挡油板21。气液滤网6的上下侧可以分别设有滤网上压板5和滤网下压板7。气液滤网6、均流板1和挡油板21从上到下设置在所述壳体内,在所述壳体底部设有积油槽22。在积油槽22的一侧(例如远离油气进口3的最右侧一端)的回油口10。In addition, the oil separator A may further include a gas liquid filter 6 and a baffle plate 21. The upper and lower sides of the gas-liquid filter 6 may be provided with a filter press plate 5 and a filter lower press plate 7, respectively. The gas-liquid filter 6, the flow plate 1 and the oil-retaining plate 21 are disposed in the casing from top to bottom, and an oil accumulation groove 22 is provided at the bottom of the casing. The oil return port 10 on one side of the oil accumulation tank 22 (for example, away from the rightmost end of the oil and gas inlet 3).
参考图7,在本实施例的油分离器A中,油气混合物M首先进入油气进口3,截面积迅速变大,气流分散呈无序状态。当撞击到两侧封板及挡油板21后,油气混合物M的大部分G绕中间封板4的底部转向进入挡油板21与均流板1的中间空间,还有一部分气流通过挡油板21进入到积油槽22后重新分配。但最终气流汇集到均流板1的底部,通过均流孔13进入气液滤网6,进行最后油气分离过程。而油气混合物M中的大部分油L通过与挡油板21的撞击分离作用而掉落到积油槽22,但仍有一部分油随着气流进入气液滤网6,而后被阻拦在气液滤网6中。当气液滤网6中油滴积累量足够大,便会沿着气液滤网6及侧封板23滴淋到均流板1上表面,再通过过液槽12流到积油槽22中,最后通过回油口10进行排油。Referring to Fig. 7, in the oil separator A of the present embodiment, the oil and gas mixture M first enters the oil and gas inlet 3, the cross-sectional area rapidly increases, and the air flow dispersion is disordered. When hitting the two side sealing plates and the oil retaining plate 21, most of the G of the oil and gas mixture M is turned around the bottom of the intermediate sealing plate 4 into the intermediate space of the oil retaining plate 21 and the flow equalizing plate 1, and a part of the airflow passes through the oil retaining The plate 21 is redistributed after entering the oil accumulation tank 22. However, the final gas stream is collected to the bottom of the flow equalization plate 1, and enters the gas liquid filter 6 through the flow equalization hole 13 to perform the final oil gas separation process. Most of the oil L in the oil and gas mixture M is dropped into the oil accumulation tank 22 by the collision with the oil baffle 21, but a part of the oil enters the gas liquid filter 6 with the air flow, and is then blocked in the gas liquid filter. In the net 6. When the oil droplet accumulation amount in the gas-liquid filter screen 6 is sufficiently large, it will drip along the gas-liquid filter screen 6 and the side seal plate 23 to the upper surface of the flow equalization plate 1, and then flow through the liquid supply tank 12 to the oil accumulation tank 22, Finally, the oil is drained through the oil return port 10.
对于上述油气进口3可以设置在壳体沿长度方向的任意一端的油分离器的实施例,均流板1从所述油气进口3所在端沿所述壳体的长度方向延伸到所述壳体的另一端。对于这种结构,过液槽12在单位长度上的数量(相当于过液槽12分布的稀疏程度)从所述油气进口3所在侧沿所述均流板1的长度方向均匀分布。An embodiment of the oil separator 3 may be disposed at any end of the housing along the length direction, and the flow plate 1 extends from the end of the oil and gas inlet 3 along the length of the housing to the housing The other end. With this configuration, the number of the liquid tanks 12 per unit length (corresponding to the degree of sparseness of the distribution of the liquid tanks 12) is uniformly distributed from the side of the oil and gas inlet 3 along the longitudinal direction of the flow equalizing plate 1.
考虑到油气进口3附近的气流比较剧烈,距离油气进口3越远气流剧烈程度会逐渐下降,因此优选靠近油气进口3一侧的过液槽12的稀疏程度相比于远离油气进口的位置更稀疏。考虑到均流孔13的孔径通常从靠近油气进口一侧到远离一侧通常设置成由小变大,这样最远一侧的均流孔的截面积已经足以满足回油,因此可以适量减少过液槽12的数量。即优选过液槽12在单位长度上的数量由第一数量到第二数量再到第三数量的方式分布,所述第一数量和所述第三数量均少于所述第二数量。也就是说,过液槽12在单位长度上的数量是从油气 进口3的所在端到远离的一端按照由少至多再变少的规律布置。同理,基于距离油气进口3越远气流剧烈程度会逐渐下降的特点,还优选过液槽12的截面积从所述油气进口3所在侧沿所述均流板1的长度方向逐渐增大。Considering that the airflow near the oil and gas inlet 3 is relatively intense, the farther the gas flow from the oil and gas inlet 3 is gradually reduced, the sparseness of the liquid tank 12 near the oil and gas inlet 3 side is preferably sparse compared to the position far from the oil and gas inlet. . Considering that the diameter of the flow equalization hole 13 is usually set from the side close to the oil and gas inlet to the far side, it is usually set to be small and large, so that the cross-sectional area of the flow hole on the farthest side is sufficient to satisfy the oil return, so that it can be appropriately reduced. The number of tanks 12. That is, it is preferable that the number of the liquid tanks 12 on the unit length is distributed from the first quantity to the second quantity to the third quantity, and the first quantity and the third quantity are both less than the second quantity. That is, the number of the liquid tanks 12 per unit length is arranged from the end of the oil and gas inlet 3 to the farther end in accordance with the rule of decreasing from less to less. Similarly, based on the feature that the intensity of the gas flow is gradually decreased from the oil and gas inlet 3, it is preferable that the cross-sectional area of the liquid tank 12 gradually increases from the side of the oil and gas inlet 3 along the length of the flow plate 1.
对于长度较短的均流板或者远端的均流孔的截面积不足以满足回油,则可以只设置成过液槽12在单位长度上的数量由第一数量到第二数量的方式分布,所述第一数量少于所述第二数量。另外,为保证均流孔的均气效果,优选所述均流板的任意侧边上的所述过液槽12在沿所述均流板的长度方向上的总长度不大于所述均流板的该侧边总长度的1/3。For the shorter length of the flow plate or the cross-sectional area of the distal flow hole is insufficient to meet the oil return, it may be arranged that only the number of the liquid flow tank 12 per unit length is distributed from the first quantity to the second quantity. The first quantity is less than the second quantity. In addition, in order to ensure the uniformity effect of the flow equalization holes, it is preferable that the total length of the liquid supply tank 12 on any side of the flow equalization plate in the longitudinal direction of the flow equalization plate is not more than the current sharing. The total length of the side of the board is 1/3.
从制冷系统整体布局分析,油气进口3在油分离器壳体的设置位置存在多变状态,除了前述的单边设置位置,还可以设置成图10所示的偏置位置或者图11所示的中间位置。From the overall layout analysis of the refrigeration system, the oil and gas inlet 3 has a variable state at the installation position of the oil separator housing, and may be set to the offset position shown in FIG. 10 or the one shown in FIG. 11 in addition to the aforementioned unilateral arrangement position. centre position.
在图10中,油气进口3设置在壳体沿长度方向的壳体长度的1/2位置与所述壳体沿长度方向的任意一端之间的偏置位置,例如1/3位置或者2/3位置。相应的,均流板1包括从该偏置位置沿所述壳体的长度方向分别延伸到所述壳体的两端的第一均流板段和第二均流板段,所述第一均流板段的长度大于所述第二均流板段的长度。In Fig. 10, the oil and gas inlet 3 is disposed at an offset position between a position 1/2 of the length of the casing in the longitudinal direction of the casing and an arbitrary end of the casing in the longitudinal direction, for example, 1/3 position or 2/ 3 positions. Correspondingly, the flow equalization plate 1 includes a first flow equalization plate segment and a second flow equalization plate segment respectively extending from the offset position along the length direction of the casing to both ends of the casing, the first The length of the flow plate section is greater than the length of the second flow equalization plate section.
对于油气进口3设置在偏置位置的油分离器A来说,较长的第一均流板段可参考前述单边形式的均流板上的过液槽12的分布方式。即第一均流板段上的所述过液槽12在单位长度上的数量从所述油气进口3所在位置分别沿所述第一均流板段的长度方向均匀分布。也可以是第一均流板段上的所述过液槽12在单位长度上的数量由第一数量到第二数量的方式分布,所述第一数量少于所述第二数量,或由第一数量到第二数量再到第三数量的方式分布,所述第一数量和所述第三数量均少于所述第二数量。For the oil separator A in which the oil and gas inlet 3 is disposed at the offset position, the longer first flow equalization plate section can refer to the distribution pattern of the liquid overflow tank 12 on the current unilaterally distributed plate. That is, the number of the liquid passing tanks 12 on the first equalizing plate section is uniformly distributed along the longitudinal direction of the first equalizing plate section from the position of the oil and gas inlet 3, respectively. It is also possible that the number of the liquid tanks 12 on the first equalizing plate section is distributed from the first quantity to the second quantity in a unit length, the first quantity is less than the second quantity, or The first quantity to the second quantity are distributed to the third quantity, the first quantity and the third quantity being less than the second quantity.
根据不同距离下油气混合物的气流剧烈程度,较短的第二均流板段上的所述过液槽12在单位长度上的平均数量低于较长的所述第一均流板段上的所述过液槽12在单位长度上的平均数量。第一均流板段 上的所述过液槽12的平均截面积也优选大于所述第二均流板段上的所述过液槽12的平均截面积。Depending on the intensity of the gas flow mixture at different distances, the average number of the liquid passages 12 on the shorter second flow equalization plate section is less than the average length on the first flow equalization plate section. The average number of the liquid tanks 12 over the unit length. The average cross-sectional area of the over-tank 12 on the first equalizing plate section is also preferably greater than the average cross-sectional area of the over-tank 12 on the second averaging plate section.
对于较短的第二均流板段,可根据其长度进行过液槽在单位长度上的数量的分布方式设计。例如对于偏置较大、长度较短的第二均流板段,则可以将其上的所述过液槽12在单位长度上的数量从所述油气进口3所在位置沿所述第二均流板段的长度方向设置成均匀分布的形式。而对于偏置较小、长度较长的第二均流板段,则可以参考前述第一均流板段的布置方式,即将其上的所述过液槽12在单位长度上的数量从所述油气进口3所在位置沿所述第二均流板段的长度方向或由第四数量到第五数量的方式分布,所述第四数量少于所述第五数量,或由第四数量到第五数量再到第六数量的方式分布,所述第四数量和所述第六数量均少于所述第五数量。For the shorter second equalizing plate section, the distribution of the number of liquid tanks per unit length can be designed according to the length thereof. For example, for a second counterflow plate segment having a large offset and a short length, the number of the liquid tanks 12 on the unit length may be from the position of the oil and gas inlet 3 along the second The length direction of the flow plate segments is arranged in a uniformly distributed form. For the second current equalizing plate segment with a small offset and a long length, reference may be made to the arrangement of the first current equalizing plate segments, that is, the number of the liquid passing tanks 12 on the unit length thereof is The position of the oil and gas inlet 3 is distributed along the length direction of the second current equalizing plate segment or from the fourth number to the fifth number, the fourth quantity being less than the fifth quantity, or by the fourth quantity The fifth number is distributed to a sixth number, the fourth number and the sixth number being less than the fifth number.
基于距离油气进口3越远气流剧烈程度会逐渐下降的特点,还优选第一均流板段上的过液槽12的截面积从所述油气进口3所在位置沿所述第一均流板段的长度方向逐渐增大。而与较短的第二均流板段相比,还优选所述第一均流板段上的所述过液槽12的平均截面积大于所述第二均流板段上的所述过液槽12的平均截面积。在设计第二均流板段上的过液槽时,可以根据第二均流板段的长度来选择适合的截面积,例如所述第二均流板段上的所述过液槽12的截面积从所述油气进口3所在位置沿所述第二均流板段的长度方向可以均相同或逐渐增大。The cross-sectional area of the over-fluid tank 12 on the first equalizing plate section is preferably along the first current-flowing plate section from the position of the oil-gas inlet 3 based on the feature that the violent degree of the gas flow is gradually decreased from the oil and gas inlet 3 The length direction gradually increases. Preferably, compared with the shorter second equalizing plate segment, it is preferable that the average cross-sectional area of the liquid passing tank 12 on the first equalizing plate segment is larger than the above-mentioned over the second current sharing plate segment. The average cross-sectional area of the liquid tank 12. When designing the over-fluid channel on the second equalizing plate section, a suitable cross-sectional area may be selected according to the length of the second averaging plate section, for example, the over-fluid tank 12 on the second averaging plate section The cross-sectional area may be the same or gradually increasing along the length direction of the second flow plate section from the position of the oil and gas inlet 3.
在图11中,油气进口3设置在所述壳体沿长度方向的所述壳体长度的1/2位置(即中间位置)。所述均流板1包括从所述油气进口3所在位置沿所述壳体的长度方向分别延伸到所述壳体的两端的第一均流板段和第二均流板段。由于油气进口位于中间位置,因此两侧的油气运行情况基本一致,因此可使第一均流板段和所述第二均流板段上的所述过液槽12对称布置,这里的对称布置既可包括布置的系数程度,也可以包括过液槽12的截面积或者形状等。In Fig. 11, the oil and gas inlet 3 is disposed at a position (i.e., an intermediate position) of the length of the casing in the longitudinal direction of the casing. The current equalizing plate 1 includes a first flow equalization plate segment and a second flow equalization plate segment extending from the position of the oil and gas inlet 3 respectively along the length direction of the casing to both ends of the casing. Since the oil and gas inlet is located at an intermediate position, the oil and gas operation conditions on both sides are substantially the same, so that the first flow plate section and the liquid flow tank 12 on the second flow plate section can be symmetrically arranged, and the symmetric arrangement here The degree of coefficient of the arrangement may be included, and the cross-sectional area or shape of the liquid tank 12 may be included.
对于第一均流板段和第二均流板段来说,其上的过液槽12在单位长度上的数量和截面积的设置方式均可参考前述油气进口3单边设 置或者偏置设置的油分离器实施例。例如将过液槽12在单位长度上的数量从所述油气进口3所在位置分别沿所述第一均流板段和所述第二均流板段的长度方向均匀分布,或由第一数量到第二数量的方式分布,所述第一数量少于所述第二数量,或由第一数量到第二数量再到第三数量的方式分布,所述第一数量和所述第三数量均少于所述第二数量。又例如,所述第一均流板段和所述第二均流板段上的所述过液槽12的截面积从所述油气进口3所在位置分别沿所述第一均流板段和所述第二均流板段的长度方向均逐渐增大。具体理由可参考前述实施例,这里就不再赘述了。For the first equalizing plate section and the second equalizing plate section, the number of the liquid tanks 12 on the unit length and the sectional area can be set by referring to the aforementioned oil and gas inlet 3 single side setting or offset setting. Oil separator embodiment. For example, the number of the liquid tanks 12 on the unit length is uniformly distributed from the positions of the oil and gas inlets 3 along the length direction of the first and second flow plate sections, respectively, or by the first quantity. Distributed to a second quantity, the first quantity being less than the second quantity, or being distributed by a first quantity to a second quantity to a third quantity, the first quantity and the third quantity Both are less than the second amount. For another example, a cross-sectional area of the liquid-passing tank 12 on the first and second equalizing plate sections is from the position of the oil-gas inlet 3 along the first current-saverage section and The length direction of the second equalizing plate section gradually increases. For specific reasons, reference may be made to the foregoing embodiments, and details are not described herein again.
在图10和图11所示的两种油气进口布置方式的实施例中,为保证均流孔的均气效果,优选所述第一均流板段的任意侧边上的所述过液槽12在沿所述均流板的长度方向上的总长度不大于所述第一均流板段的该侧边总长度的1/3;和/或所述第二均流板段的任意侧边上的所述过液槽12在沿所述均流板的长度方向上的总长度不大于所述第二均流板段的该侧边总长度的1/3。In the embodiment of the two oil and gas inlet arrangement modes shown in FIG. 10 and FIG. 11 , in order to ensure the equalization effect of the flow sharing holes, the over-liquid tank on any side of the first flow equalization plate section is preferred. The total length in the longitudinal direction of the current equalizing plate is not more than 1/3 of the total length of the side of the first flow equalizing plate segment; and/or any side of the second current sharing plate segment The total length of the over-tank 12 on the side in the longitudinal direction of the flow equalization plate is not more than 1/3 of the total length of the side of the second flow equalization plate section.
