Abstract
一种用于炼油塔中的液体分离器，采用旋流喷射方式，炼油塔中仅需采用一个喷头。这种分布器结构上为单喷头，其内设有一个旋流发生器，在其后设有一混合腔和一收缩-扩张型锥形喷嘴，旋流发生器为导流片式，在导流片上开有一孔。当原油由进口进入旋流器经分流，并通过混合腔获得合适的轴向、切向、径向速度后，由收缩-扩张锥形喷嘴喷出。结构简单，喷出口散布度均匀。
The utility model relates to a liquid separator used in an oil refinery tower, which adopts a swirling flow injection method, and only one spray head is required in the oil refinery tower. The structure of this distributor is a single nozzle, which is equipped with a swirl generator, followed by a mixing chamber and a contraction-expansion conical nozzle. The swirl generator is a deflector type. There is a hole in the sheet. When the crude oil enters the cyclone from the inlet, it is divided, and after obtaining the appropriate axial, tangential, and radial velocities through the mixing chamber, it is ejected from the contracting-expanding conical nozzle. The structure is simple, and the distribution of the spray outlet is uniform.
Description
The utility model relates to petrochemical industry and is used for refining oil a kind of liquid uniform distribution device of tower.
Liquid distribution trough in the petroleum refining production at present in the oil refining tower generally adopts many spray nozzle types of support rack type structure.This method is that feedstock oil is sprayed distribution by a plurality of shower nozzles of arranging by certain way that are fixed on the pole.The shortcoming of this method is that the distribution of liquid uniformity is poor, and it is bigger influenced by the distributing position of shower nozzle, and often the liquid distribution amount is big under shower nozzle, and departs from place far away, the vertical position of shower nozzle, and the liquid distribution amount is little, even is zero.The result influences mixing of feedstock oil and other working medium, and extracting rate is low.
The purpose of this utility model is achieved in that on the structure to be a single shower nozzle, a rotational flow generator is set behind its inducer, in its back a hybrid chamber and a contraction---expanding conical nozzle is arranged, rotational flow generator is the water conservancy diversion chip, has a hole on the flow deflector.Feedstock oil, sprays by tapered nozzle through behind the rotational flow generator from intake header.Feedstock oil obtains suitable axial, tangential, radial velocity through behind the rotational flow generator, thereby guarantees that the ejection back is even along the distribution degree of each horizontal plane.
Fig. 1 is the profile of the swirl injection type liquid distribution device that the utility model proposes.
Fig. 2 is that the A-A of Fig. 1 is to profile.
Below in conjunction with Fig. 1, Fig. 2 architectural feature of the present utility model, embodiment and working condition being done one describes in detail: a device of the present utility model comprises an inducer 1, a rotational flow generator 2 is set thereafter, a pair of eddy flow prerotation vane 3 is arranged in the rotational flow generator 2, one hybrid chamber 5 and a contraction---expanding conical nozzle 6 is set at rotational flow generator 2 rear portions.The inclination angle of prerotation vane 3 is preferably 25 °-30 °, and this device adopts 30 °, respectively opens a hole 4 in the middle part of two prerotation vanes 3 to increase axial flow.Shrinking---the outlet semiapex angle of expanding conical nozzle 6 is 45 °.Base regime of the present utility model is, feedstock oil enters rotational flow generator 2 by inducer 1, after 3 shuntings of eddy flow prerotation vane, in hybrid chamber 5, mix, then by shrinking---6 ejections of expanding conical nozzle, owing to ejection is expanded in shunting, mixing and contraction back, make crude oil acquisition suitable axial, tangential, radial velocity, thus even after the assurance ejection along the distribution degree of each horizontal plane.
The utility model has saved support, so simple in structure because only need directly link to each other with intake header; It is constant that rotational flow generator produces swirling number simultaneously, makes under the unsettled operating mode of inlet flow rate, also can make the ejection liquid dissemination even, and the distribution degree is big.It is initial point with nozzle under vertical that the utility model is used for one, from the initial point to the radius is to carry out liquid dissemination in 1.6 meters the scope to measure, and the liquid in container height of measuring flow is 9.0 ± 1.0 centimetres, and the distribution degree is even; And after exceeding the scope of 1.6 meters of desired radiuses, the liquid height in the measuring vessel is bordering on zero.
Claims (2)
1, a kind of liquid distribution trough that is used for refining oil tower is characterized in that being provided with a rotational flow generator behind its inducer, and a hybrid chamber and a contraction---expanding conical nozzle is arranged in its back, and rotational flow generator is the water conservancy diversion chip, has a hole on the flow deflector.
2, liquid distribution trough according to claim 1, the inclination angle that it is characterized in that the eddy flow prerotation vane are 25 °-30 °.
