Abstract
The utility model discloses a suction-breaking flow-type gas-liquid distributor used for the hydrogenation reactor in the petroleum refining. The utility model is characterized in that four rectangular holes which are distributed symmetrically are opened on the top of a central tube. The lower part of the central tube is a trumpet-shaped flaring. A disk-shaped breaking flow device is arranged under the flaring. Six notches in the shape of an isosceles triangle are uniformly opened at the lower part of a circular bubble cap. Adopting the distributor, the homogeneity of the integral distribution and the local distribution of the bed material of the hydrogenation reactor can be improved thoroughly. The contact of the catalyst and the material is more sufficient and uniform. The temperature difference in the cross-section of the bed is reduced maximally. The quality of the petroleum product is improved, and the cost of production is reduced.
Description
This device belongs to the internals of hydrogenation reactor in the petroleum refining.
For realizing the even distribution to hydrogenation reactor inside gas-liquid two-phase feeding, people disclose multiple gas-liquid distributor.Estimate, weigh the quality of a distributor distribution performance, the one, see whether the distributing homogeneity of fluid on whole distribution cross section that is distributed be good, and promptly whether the overall distribution characteristic is good; The 2nd, see whether the uniformity that is distributed fluid on the cross section in each definite zone is good, and promptly whether the local distribution uniformity is good.The disclosed circular bubble cap type gas-liquid distributor of U.S. Union oil company is exactly wherein a kind of.We find that by a large amount of experiments circular bubble cap type gas-liquid distributor has the good whole distributing homogeneity, but wherein the local distribution characteristic is very poor, promptly the liquid phase thing more than 70% is concentrated and to be distributed under its central tube in the view field, make in this zone liquid measure intensive, cause material can not be uniformly distributed in the reactor catalyst bed face, abundant, the homogeneous that have influenced reaction carry out.
The purpose of this utility model provides a kind of whole uniformity and local uniformity is all well aspirated broken flow pattern gas-liquid distributor, so that material fully contacts with catalyst, reduce the temperature difference in the hydrogenation reactor bed cross section, improve oil quality, reduce production cost.
The utility model is achieved in that a broken flow pattern gas-liquid distributor of being made up of central tube (5), round bubble cap (7), clamp (3), nut (1), screw rod (2) of suction, it is characterized in that: central tube (5) bottom is horn-like enlarging, the top is provided with the rectangular indentation (4) of 4 symmetrical distributions, and is fixed on the distribution grid (9) by snap ring (8); Central tube (5) lower part outlet place is provided with disc blowgun (13), and blowgun (13) is bound up on the exit of central tube (5) by three ribs (11); Have 6 uniform vees (6) on the circular bubble cap (7), bubble cap (7) is bound up on the central tube (5) by nut (1), screw rod (2), clamp (3).Referring to Fig. 1, carry under one's arms liquid phase when rising to annulus top when gas phase, mixed flow can enter central tube from the differing heights of breach, and flows to relatively, clashes, and has increased the lateral momentum of mixed flow, is beneficial to the expansion of distribution.Circular bubble cap bottom has 6 uniform isoceles triangle v notch vs (6).Proof by experiment, the stationarity that this breach form helps operating, promptly under the gas-liquid flow condition of broad, the distribution character that distributor can both held stationary.The disc blowgun (13) that has ease discharge orifice (12), its effect is: when the intensive liquid in center flows the high speed impact blowgun, the charging of being clashed into promptly can be splashed and is scattering in the big zone beyond the center, and a small amount of charging enters the central area via spout hole (12).
The diameter of the disc blowgun in the utility model is about half of centre bore internal diameter, has a plurality of ease stream circular holes on the blowgun, and its percent opening is about 5%.
6 uniform vees of circular bubble cap bottom in the utility model are isoceles triangle v notch vs, and the triangle base is 1:3 with the ratio of its height.
Experiment shows that this distributor is compared with circular bubble cap type gas-liquid distributor, and material distribution circle area increases by 150～200%, and it is about 300% that the local distribution uniformity improves, and the work elasticity of distributor strengthens.Suitable gas, liquid loading range enlarges, thereby the catalyst bed laminar surface that makes material can be uniformly distributed in reactor reacts fully, homogeneous.
Description of drawings:
Fig. 1 is the main cutaway view of the broken flow pattern gas-liquid distributor structure of suction.
Further specify in conjunction with the accompanying drawings:
This device mainly comprises central tube (5), circular bubble cap (7), disc blowgun (13).The top of central tube (5) is provided with the rectangular indentation (4) of four symmetrical distributions and the clamp (3) of standing screw (2), the bottom is loudspeaker enlarging (10), loudspeaker enlarging (10) connects disc blowgun (13) by three ribs (11), by snap ring (8) central tube (5) is fixed on the interior distribution grid (9) of hydrogenation reactor.The top of circular bubble cap (7) has to connect uses through hole, skirt section to have six uniform isoceles triangle v notch vs (6); And, form a broken flow pattern gas-liquid distributor of complete suction by nut (1), screw rod (2) and central tube (5) connection.The broken flow pattern gas-liquid distributor of a plurality of this suctions is housed on the bed distribution grid (9) in hydrogenation reactor.
