Abstract
The utility model relates to a scale depositing device comprising a regularly-decagon connecting frame which is arranged at two ends of the scale depositing device; a framework is arranged at each inner corner of the connecting frame; a strip-shaped filter screen is arranged between the two adjacent frameworks; an annular baffle cap is arranged on the top surface of the connecting frame; and a cover plate is arranged on the baffle cap at the top of the scale depositing device. The scale depositing device provided by the utility model has the advantages of firm structure, reliability in operation, small occupying space, strong scale depositing capability and the like. The scale depositing device has the effects of scale depositing buffering and material distribution, during the using process, materials entering form an inlet of a reactor fall on a bottom plate, then enter the scale depositing device form the outer side of a sieve hole in the scale depositing device, and fall to a catalyst bed layer, the cross section of the scale depositing device is small, a barrel body is tall, so that even if the lower end of the scale depositing device is plugged, the pressure drop is not increased as liquid enters from a sieve hole in the upper part after the liquid level rises. The scale depositing device well improves the defects in the prior art, and has a good economic benefit.
Description
Technical field
The utility model relates to a kind of hydrogenation reactor, especially relates to a kind of sump for hydrogenation reactor.
Background technology
In petroleum refining industry, adopt the high-temperature and high-pressure hydrogenation purification techniques history of existing nearly half a century.Improvement along with technologies such as hydrocracking and hydrodesulfurizations, the increase of light-end products demand, and the heavy oil feedstock crack refinement, air conservations etc. need, its structure of the nucleus equipment-hydrogenation reactor of hydro-refining unit and hydrocracking unit and parts constantly carry out perfect.For the downflow system hydrogenation fixed bed reactors of gas and liquid flowing, its inner member generally includes inlet diffuser, gas-liquid allotter, sump, cold hydrogen box, thermocouple and exit collector etc.
The reactor end socket space that the sump utilization was left unused originally, improve the space reactor utilization rate, can increase desulfurization, receive the ability of dirt, the extension reactor cycle of operation, improve the fluid nowed forming of first bed, simplify the inlet diffuser structure, on the many suspensions of sump and the beam, string with iron chains, it takes up room greatly, incrustation is indifferent, and sediment incrustation basket is through after a while running, also usually stops up, problem such as pressure drop rising.
Summary of the invention
The purpose of this utility model provides a kind of sump, technical problems such as existing sump takes up room greatly, incrustation is indifferent, pressure drop is big to improve, easy obstruction.
The utility model mainly solves the problems of the technologies described above by following technical proposals: a kind of sump, the link that comprises the regualr decagon that is arranged on the sump two ends, each interior angle place of this link is provided with skeleton, be provided with the strip filter screen between the adjacent skeleton, the link end face is provided with the baffle plate cap of annular, and the baffle plate cap at sump top is provided with cover plate.
As preferably, described strip filter screen is made of the many gratings that parallel equidistant is welded on the skeleton, and the cross section of this grating is triangle.
As preferably, in the described strip filter screen, form bar shaped screen hole between the two adjacent gratings.
The utlity model has sound construction, reliable, little, advantage such as the incrustation ability is strong takes up room.This sump has the effect that slows down incrustation and material distribution, in use, the material that enters from reactor inlet drops on the base plate, the outside, sieve aperture hole from sump enters sump then, fall into beds subsequently, the sump cross section is little and stack shell is high, even the sump lower end is stopped up, liquid level rises the back from the inflow of top sieve aperture, can not cause pressure drop to increase.The utility model has well improved the deficiency of existing sump, has good economic benefits.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 be the utility model A-A to cutaway view;
Fig. 3 is scheme of installation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.Fig. 1 is structural representation of the present utility model, Fig. 2 be the utility model A-A to cutaway view, Fig. 3 is scheme of installation of the present utility model.As seen from the figure, this sump comprises the link 1 of the positive icosagon that is arranged on the sump two ends, and link 1 each interior angle place is provided with skeleton 2, is provided with strip filter screen 3 between the adjacent skeleton 2, and strip filter screen 3 both sides are welded on the skeleton 2.
In the application process, described sump is arranged on the base plate, sump on base plate with triangular arrangement.
In hydrogenation reactor when work,, material falls from reactor inlet, run into base plate after, be diffused on the sump, material distributes at a plurality of sumps, the sieve aperture that material passes on the filter screen enters beds.Colloid in the material, impurity and suspended particulate are blocked in outside the sump.Along with increasing running time, impurity stops up the distributor lower end on the liquid level of back and move, and little and stack shell is long because of the sump sectional area, material can flow into from top, and can not cause the pressure drop increase.
At last, should be pointed out that the above specific embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the above-mentioned specific embodiment, and many distortion can also be arranged.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done the above specific embodiment all should be thought to belong to protection domain of the present utility model.
Claims (3)
1. sump, the link that comprises the regualr decagon that is arranged on the sump two ends, it is characterized in that each interior angle place of this link is provided with skeleton, be provided with the strip filter screen between the adjacent skeleton, the link end face is provided with the baffle plate cap of annular, and the baffle plate cap at sump top is provided with cover plate.
2. a kind of sump according to claim 1 is characterized in that described strip filter screen is made of the many gratings that parallel equidistant is welded on the skeleton, and the cross section of this grating is triangle.
