Abstract

The utility model discloses a gaseous raw oil distributor which comprises a lower distribution body and an upper distribution body, wherein the lower distribution body is formed by combining a plurality of homocentric lower ring bodies (2) and a plurality of lower grid plates (5); the upper distribution body is positioned on the lower distribution body and formed by combining at least one concentric upper ring body (3) and a plurality of upper grid plates (1). The gaseous raw oil distributor is radial; and distribution holes (4) are formed on each of the lower ring bodies (2) at intervals. As the gaseous raw oil distributor is radial, the gaseous raw oil distributor radiates from the center to the outside, and as the upper ring bodies and the lower ring bodies have high density and large flowing resistance, the flowing resistance of a central part of the gaseous raw oil distributor shrinks gradually from the center to the outside; and the upper grid plates and the lower grid plates which are dispersed and the upper ring bodies and the lower ring bodies which are corrugated are uniformly distributed at the top of the reactor automatically under the action of the corresponding resistance like gaseous raw oil led by a ditch. The gaseous raw oil uniformly and equivalently flows in the reactor so as to improve the reaction effect of the gaseous raw oil.

Description

The gaseous feed oil dispenser

Technical field

The utility model relates to the distributor in the petrochemical industry smelting reactor, especially relates to a kind of distributor that is used for the oil flow of reactor gaseous feed.

Background technology

In the petrochemical industry smelting process, gaseous feed oil enters the back liquid expansion that fails to be convened for lack of a quorum from reactor head, owing to the short circuit reason, gaseous feed oil passes through easily in the centre, and its flow resistance is less, and therefrom the heart reduces gradually out to the marginal flow kinetic force, flow resistance increases gradually, thereby make gaseous feed oil flow distribution on reactor cross-section just evenly little, thus cause gaseous feed oil in reactor, to react little balanced, influence the reaction effect of gaseous feed oil.

The utility model content

At the uneven problem that flows that in reactor, distributes of gaseous feed oil in the above-mentioned prior art, the utility model provide a kind of make gaseous feed oil enter reactor after flow distribution even, help improving the gaseous feed oil dispenser of gaseous feed oil reaction effect.

The technical scheme that the technical problems to be solved in the utility model is taked is: described gaseous feed oil dispenser comprise the following minute part that is combined to form by a plurality of concentric following torus and polylith lower grid plate and be positioned on the following part of minuteing by at least two concentric last torus and polylith top grating be combined to form on a minute part, described gaseous feed oil dispenser is radially.

The utility model gaseous feed oil dispenser since radially by the center to external radiation, its centre makes flow resistance big owing to upper and lower torus and upper and lower screen density are high, and therefrom outer its density of mind-set reduces, flow resistance reduces gradually, be the upper and lower screen of the shape that scatters and be corrugated upper and lower torus and resemble irrigation canals and ditches guiding gaseous feed oil under the effect of corresponding resistance, be evenly distributed on the top of reactor automatically.Gaseous feed oil is flowing of even equivalent in reactor, thereby can improve the reaction effect of gaseous feed oil.

The specific embodiment

In Fig. 1, Fig. 2 and Fig. 3, described gaseous feed oil dispenser comprises branch part and following minute part, described going up divides part to be combined to form by two concentric last torus 3 and 24 top grating 1 welding, described top grating is evenly spaced apart radially, last torus equates with the top grating height, top grating is concordant to pass torus on all, and going up torus and top grating height certainly also can be unequal, and top grating also can interlock and pass torus on all; Described following minute part is combined to form by eight concentric following torus 2 and 12 lower grid plate 5 welding, described lower grid plate is evenly spaced apart radially, following torus equates with the lower grid plate height, concordant all torus down that pass of lower grid plate, certainly torus and lower grid plate height also can be unequal down, and lower grid plate also can interlock and pass all torus down.The described torus of going up all is positive 20 quadrangles with following torus, certainly the described torus of going up also can be other regular polygon with following torus, for further making flowing evenly of gaseous feed oil, on all following torus that divide down on the part, preferably be arranged at intervals with dispensing orifice 4, described dispensing orifice is the strip hole, can certainly be the hole of circular hole, mounting hole or other shape.Except that illustrated structure, described down torus can be six, ten, 12,15,16 outer, 18,20,24 etc. other are a plurality of, described lower grid plate also can be other polyliths such as eight, ten, 16,20; Described go up torus also can be one, three, four, five etc. a plurality of; described top grating also can 20,18,20 etc. other polylith, the various similar gaseous feed oil dispenser that they are formed all should be in protection domain of the present utility model.

Claims

1. gaseous feed oil dispenser, it is characterized in that: it comprise the following minute part that is combined to form by a plurality of concentric following torus (2) and polylith lower grid plate (5) and be positioned on the following minute part by at least one concentric last torus (3) and polylith top grating (1) be combined to form on a minute part, described gaseous feed oil dispenser is radially.

2. gaseous feed oil dispenser according to claim 1 is characterized in that: be arranged at intervals with dispensing orifice (4) on the torus (2) down described.
