Description

一种旋流气液、液液分离器 A cyclone gas-liquid, liquid-liquid separator

技术领域 technical field

本发明涉及一种分离器,特别是涉及一种用于工业上互不相溶,且具有密度差的气液或液液的初步分离的螺旋管旋流气液、液液分离器。The invention relates to a separator, in particular to a helical tube swirl gas-liquid and liquid-liquid separator used for preliminary separation of gas-liquid or liquid-liquid which are industrially immiscible and have density difference.

背景技术 Background technique

目前,离心力和重力分离原理被广泛用于分离领域,其中以具有锥形筒的旋风分离器为代表。由于旋风分离器内流体的流动产生一定的剪切作用,容易将液滴(油滴或水滴)打碎乳化而恶化分离过程;而且旋风分离器通用性较差。因此用来进行液液分离效果并不理想。螺旋管具有截面小的特点,可以避免上述因素的影响。专利号为01206727.X的螺旋式气液分离器就是利用螺道产生离心力来实现气液分离的,但是该装置不能用来进行液液分离。At present, the principles of centrifugal force and gravity separation are widely used in the field of separation, among which the cyclone separator with a conical cylinder is the representative. Because the flow of the fluid in the cyclone separator produces a certain shearing effect, it is easy to break and emulsify the liquid droplets (oil droplets or water droplets) and deteriorate the separation process; and the cyclone separator has poor versatility. Therefore, it is not ideal for liquid-liquid separation. The spiral tube has the characteristics of small cross-section, which can avoid the influence of the above factors. The spiral gas-liquid separator with the patent No. 01206727.X utilizes the centrifugal force generated by the spiral to realize gas-liquid separation, but this device cannot be used for liquid-liquid separation.

在上述技术方案中,螺旋管主体1的螺旋管设计参数遵循以下关系:In the above technical solution, the spiral tube design parameters of the spiral tube main body 1 follow the following relationship:

450 ≤ 2 πR ( N - 4 ) D 1 ≤ 500 , 2 ≤ H D 2 ≤ 2.5 ; 其中R、D1、D2的取值在如下范围内最合适:150mm≤R≤200mm,20mm≤D1≤30mm、25mm≤D2≤35mm。 450 ≤ 2 πR ( N - 4 ) D. 1 ≤ 500 , 2 ≤ h D. 2 ≤ 2.5 ; Among them, the values of R, D 1 and D 2 are most suitable in the following ranges: 150mm≤R≤200mm, 20mm≤D 1 ≤30mm, 25mm≤D 2 ≤35mm.

在上述技术方案中,所述的螺旋管主体1的螺旋管封闭段14的圈数为N-4圈。In the above technical solution, the number of turns of the closed section 14 of the spiral tube body 1 is N-4.

在上述技术方案中,所述的调整段16设置在第一圈所开圆孔15与第二圈所开圆孔15之间间隔的半圈不带孔的螺旋管段,第二圈螺旋管所开圆孔15与第三圈所开圆孔15之间间隔半圈的螺旋管段,所以螺旋管主体1的螺旋管上部分总共为4圈带孔段13;所述的调整段16为相邻两圈小孔之间的一段不带孔的螺旋管,所述的调整段长度为1/2圆周。In the above technical solution, the adjustment section 16 is set in the half-circle spiral pipe section without holes between the first round hole 15 and the second round hole 15, and the second round spiral pipe section There is a half-circle helical tube section between the round hole 15 and the third round hole 15, so the upper part of the helical tube of the helical tube main body 1 is a total of 4 circles with holes 13; the adjustment section 16 is adjacent A section of helical tube without holes between two circles of small holes, the length of the adjustment section is 1/2 circle.

在上述技术方案中,所述的螺旋管主体1的螺旋管上的4圈带孔段13,从螺旋管上部自上到下3圈小孔的数目分别为n1、n2、n3,孔径分别为d1、d2、d3;圆孔的数目和孔径应遵循以下设计准则:n1≤n2≤n3,d1≤d2≤d3In the above technical solution, the numbers of the 4 circles of holed sections 13 on the spiral tube of the spiral tube main body 1 are n 1 , n 2 , n 3 respectively from top to bottom of the spiral tube, The apertures are d 1 , d 2 , and d 3 respectively; the number and aperture of circular holes should follow the following design criteria: n 1 ≤n 2 ≤n 3 , d 1 ≤d 2 ≤d 3 .

在上述技术方案中,所述的支架2由圆盘9、立管10和固定组件组成;其中固定组件包括调节螺母11、管托12、管扣13、螺栓14;所述的立管10共有三根,上部带有一段螺纹,底部连接在圆盘底座上,这三根立管长度不同,可以分别支撑螺旋管的上中下部分;管托12由上下两个调节螺母11固定在上述立管10螺纹段的合适高度上,螺旋管被夹持在管扣13和管托12之间,并由螺栓14锁紧。由于不同流量下容器7中液面高度也不同,而螺旋管的带孔段的位置要始终高于液面才能正常工作。因此可以用管托支持螺旋管的不同位置实现螺旋管高度的调节,以适应不同工况下的液面高度。In the above technical solution, the support 2 is composed of a disc 9, a standpipe 10 and a fixing assembly; wherein the fixing assembly includes an adjusting nut 11, a pipe holder 12, a pipe buckle 13, and a bolt 14; the riser 10 has a total Three, the upper part has a thread, and the bottom is connected to the disc base. The three standpipes have different lengths and can support the upper, middle and lower parts of the spiral pipe respectively; the pipe support 12 is fixed on the above-mentioned standpipe 10 by two upper and lower adjustment nuts 11 At the appropriate height of the threaded section, the spiral pipe is clamped between the pipe buckle 13 and the pipe holder 12, and is locked by the bolt 14. Since the height of the liquid level in the container 7 is different under different flow rates, the position of the holed section of the spiral tube must always be higher than the liquid level to work normally. Therefore, the height of the spiral tube can be adjusted by using the different positions of the tube support to support the spiral tube, so as to adapt to the liquid level under different working conditions.

在上述技术方案中,所述的固定组件由管托12、管扣13、调节螺母11和螺栓14组成,其中管托12为一试管夹形式,一端扁平状,其上开有两个螺孔,和有一个管托凸起17;管托12的另一端可以是半圆形状的金属环,或者是两个半圆形状的金属环,在金属环上开有螺孔,通过螺钉穿过螺孔用上下两个调节螺母11,将固定组件固定在立柱上部;管扣13为一金属板,其上开有两个螺孔,和有一个管扣凸起18,两个螺孔的位置与管托12上的两个螺孔相对应,管扣凸起18与管托凸起17;管托12和管扣13之间夹持螺旋管,管托12和管扣13螺孔相对,并用螺栓14锁紧,这样支架和螺旋管就组成了一个整体。In the above technical solution, the fixing assembly is composed of a tube support 12, a tube buckle 13, an adjusting nut 11 and a bolt 14, wherein the tube support 12 is in the form of a test tube clamp, one end is flat, and two screw holes are opened on it , and there is a tube holder protrusion 17; the other end of the tube holder 12 can be a semicircular metal ring, or two semicircular metal rings, and a screw hole is provided on the metal ring, and the screw passes through the screw hole to use Two adjustment nuts 11 up and down fix the fixing assembly on the top of the column; the pipe buckle 13 is a metal plate with two screw holes and a pipe buckle protrusion 18, the positions of the two screw holes are consistent with the pipe support The two screw holes on 12 correspond to each other, the pipe buckle protrusion 18 and the pipe support protrusion 17; the spiral pipe is clamped between the pipe support 12 and the pipe buckle 13, the pipe support 12 and the pipe buckle 13 screw holes are opposite, and the bolt 14 Lock it tightly, so that the bracket and the spiral tube form a whole.

其中带孔段上设置调整段16,该调整段为相邻两圈小孔之间的一段不带孔的螺旋管,所述的调整段长度为1/2圆周;就是考虑到受小圆孔射流的影响,混合液流经每一圈带孔螺旋管后分层状态会受到一定干扰,马上进入下一圈带孔螺旋管分离将会影响到分离效果。因此设计了一段不带孔螺旋管作为“调整段”,当混合液流过该“调整段”时会重新分层从而消除这种干扰的影响。Wherein the adjustment section 16 is set on the section with holes, and this adjustment section is a spiral tube without holes between two adjacent circles of small holes, and the length of the adjustment section is 1/2 circumference; Influenced by the jet flow, the layered state of the mixed liquid will be disturbed to a certain extent after passing through each circle of perforated spiral tube, and immediately entering the next circle of perforated spiral tube for separation will affect the separation effect. Therefore, a section of helical tube without holes is designed as an "adjustment section", and when the mixed liquid flows through the "adjustment section", it will be re-stratified to eliminate the influence of this interference.

其中螺旋管上还设计了螺旋管封闭段采用管壁封闭,这样的设计是为了使混合流体在进入带孔段进行分离之前,有足够长的时间受到离心力和重力的联合作用,分层更为充分,从而加强在带孔部分的分离效果。Among them, the closed section of the spiral tube is also designed on the spiral tube to be closed by the tube wall. This design is to make the mixed fluid have a long enough time to be subjected to the combined action of centrifugal force and gravity before entering the section with holes for separation, and the stratification is more accurate. Sufficiently, thereby enhancing the separation effect in the perforated part.

本发明的优点在于:The advantages of the present invention are:

本发明的气液、液液分离器,利用两种互不相溶的、且密度不同的两种混合流体(两种液体或是气体和液体)存在密度差,在螺旋管中流动的时候会受到离心力和重力的联合作用而产生分层现象;密度较小的流体主要集中在管截面内侧偏上的位置;密度较大的流体则主要集中在管截面外侧偏下的位置,在螺旋管的外侧开上小孔,就会有一部分管截面外侧的液体顺着小孔流出,这部分液体主要为密度较大的流体;而管内剩下的主要是另一种流体,它们会从螺旋管的出口流出,将从小孔和螺旋管出口流出的流体分别收集起来,实现了两种流体的初步分离。The gas-liquid and liquid-liquid separator of the present invention utilizes two kinds of mixed fluids (two kinds of liquids or gas and liquid) that are immiscible with each other and have different densities to have a density difference, which will The delamination phenomenon is caused by the combined action of centrifugal force and gravity; the fluid with lower density is mainly concentrated in the upper part of the inner side of the tube section; the fluid with higher density is mainly concentrated in the lower part of the outer side of the tube section. If a small hole is opened on the outside, a part of the liquid on the outside of the tube section will flow out along the small hole. This part of the liquid is mainly a fluid with a higher density; The outlet flows out, and the fluids flowing out of the small hole and the outlet of the spiral tube are collected separately, and the preliminary separation of the two fluids is realized.

该分离器体积小、重量轻、结构简单、分离效率高,特别适合海上平台等特殊场合下的多相分离。另外具有压力损失小,节省能耗,以及通过调节进出口阀门,可以适应不同粘度不同配比的混合液分离,使分离达到最佳状态。The separator is small in size, light in weight, simple in structure and high in separation efficiency, and is especially suitable for multi-phase separation in special occasions such as offshore platforms. In addition, it has the advantages of small pressure loss, energy saving, and by adjusting the inlet and outlet valves, it can adapt to the separation of mixed liquids with different viscosities and different proportions, so that the separation can reach the best state.

具体实施方式 Detailed ways

实施例1:Example 1:

参照图1,制作一带有螺旋管的旋流气液、液液分离器;下面结合附图和实施例对本发明进行详细说明:With reference to Fig. 1, make a cyclone gas-liquid, liquid-liquid separator with spiral tube; The present invention is described in detail below in conjunction with accompanying drawing and embodiment:

本实施例的螺旋管主体1采用不锈钢管制成螺旋管具有总圈数N=15.5,螺旋管回转半径R=200mm,螺旋管的螺距H=70mm,螺旋管的管内径D1=29mm,螺旋管的管外径D2=32mm;螺旋管主体1的螺旋管上部1-4圈为开孔段,余下部分为封闭段。开孔段的螺旋管第一圈开有6个圆孔15,即n1=6,d1=2.5mm;第二圈开有6个圆孔15,即n2=6,d2=3mm;第三圈开有8个圆孔15,即n3=8,d3=3.5mm;螺旋管主体1带孔段开孔的位置如图2A、图2B、图2C、图2D所示。本实施例的圆孔15从距离输出管6的出口1/4圆周处开始开孔,并且圆孔15均匀开在螺旋管的外侧,与水平线成α=45°夹角。因为在离心力和重力的作用下,两种流体的界面不再是水平的而是与水平线有个夹角,而界面的中垂线与管壁的交点是最利于液体流出分离的位置,因此选择上述开孔角度;从上到下3圈小孔的数目分别为n1、n2、n3,孔径分别为d1、d2、d3;考虑到混合液在流经螺旋管的带孔段时,一部分密度较大的流体顺着小孔流出,管内该流体的流量随之减小,因此小孔的数目和孔径遵循了以下设计准则:n1≤n2≤n3,d1≤d2≤d3The spiral pipe main body 1 of the present embodiment is made of stainless steel pipe, and the spiral pipe has a total number of turns N=15.5, the radius of gyration of the spiral pipe R=200mm, the pitch H=70mm of the spiral pipe, and the inner diameter of the spiral pipe D 1 =29mm, the spiral pipe The outer diameter of the pipe is D 2 =32mm; the upper 1-4 circles of the spiral pipe of the spiral pipe main body 1 are opening sections, and the remaining part is a closed section. There are 6 circular holes 15 in the first circle of the spiral tube of the opening section, that is, n 1 =6, d 1 =2.5mm; the second circle has 6 circular holes 15, that is, n 2 =6, d 2 =3mm ; There are 8 circular holes 15 in the third circle, namely n 3 =8, d 3 =3.5mm; the position of the hole section of the spiral tube main body 1 is shown in Fig. 2A, Fig. 2B, Fig. 2C, and Fig. 2D. The circular hole 15 of the present embodiment starts opening at the 1/4 circumference of the outlet of the output pipe 6, and the circular hole 15 is evenly opened on the outside of the spiral tube, forming an angle of α=45° with the horizontal line. Because under the action of centrifugal force and gravity, the interface of the two fluids is no longer horizontal but has an angle with the horizontal line, and the intersection point of the vertical line of the interface and the pipe wall is the most favorable position for the liquid to flow out and separate, so choose The above-mentioned opening angle; the number of small holes in the three circles from top to bottom are n 1 , n 2 , n 3 , and the apertures are d 1 , d 2 , d 3 ; During the period, a part of the fluid with higher density flows out along the small holes, and the flow rate of the fluid in the pipe decreases accordingly. Therefore, the number and diameter of the small holes follow the following design criteria: n 1 ≤ n 2 ≤ n 3 , d 1 ≤ d 2d 3 .

本实施例的调整段16设置在第一圈所开圆孔15与第二圈所开圆孔15之间间隔的半圈不带孔的螺旋管段,第二圈螺旋管所开圆孔15与第三圈所开圆孔15之间间隔半圈的螺旋管段,所以螺旋管主体1的螺旋管上部分总共为4圈带孔段13。上述的螺旋管主体1的螺旋管上不带孔的螺旋管段为调整段16。第1段位于第1圈最后一个小孔和第2圈第一个小孔之间,第2段位于第2圈最后一个小孔和第3圈第一个小孔之间,调整段16长度为1/2圆周。The adjustment section 16 of the present embodiment is arranged on the half-circle helical tube section without holes between the first round hole 15 and the second round hole 15, and the second round hole 15 and the second round hole. The circular holes 15 opened in the third circle are separated by a half circle of helical tube sections, so the upper part of the helical tube of the helical tube main body 1 has four circles of holed sections 13 in total.
