Abstract
The utility model relates to a middle pressure equalizing type absorption tower mainly comprising an absorption tower and a pressure equalizer, wherein the pressure equalizer is arranged in the middle of a middle tower body, so that the middle tower body can be connected with a high pressure gas source and the absorption tower similarly provided with the pressure equalizer by using a pipeline and a valve; large-area gas dissipation or gas collection can be performed inside the absorption tower, and rapid pressure equalizing can be performed on two or plurality of absorption towers which are communicated mutually and similarly provided with the pressure equalizers; a gas dissipation pipe segment provided with gas dissipation holes is extended into the internal cavity of the middle tower body, large-area gas collecting can be performed in the absorption tower in high pressure state and large-area gas dissipation can be performed in the absorption tower in low pressure state, so that the impact force of gas flow on absorbents can be relieved; and the outer surface of the gas dissipation pipe segment is covered with a screen, so that the absorbent can be isolated and the loss of the absorbent can be avoided. Due to the technical scheme, the structure is simple and the function and effect in the aspects of relieving the impact force of gas flow, rapidly equalizing pressure of the absorption tower and the like are remarkable by only arranging the pressure equalizer is , and the structure of the absorption towers is improved.
Description
Technical field:
The utility model relates to air separation plant, is particularly useful for the adsorption tower of divided gas flow.
Background technology:
The adsorption tower of existing air separation plant mainly by at the bottom of body of the tower and flange, top cover, the tower, bolt, air inlet, gas outlet, exhaust outlet form.
With existing adsorption tower purified gases, in the process of finishing purifying and dry gas, because the pressure that the pressure in two adsorption towers is obviously different, the pressure of high-pressure air source and the adsorption tower of low-pressure state are interior is also obviously different, be again in the extremely short time and in adsorption tower bottom feeding gases at high pressure, to obtain even the pressure, tend to occur such phenomenon: the air-flow of high-pressure air source and the interior high pressure draught of the adsorption tower of locating high pressure conditions, the adsorbent in the adsorption tower of severe impact place low-pressure state simultaneously causes adsorbent to shorten without reason service life.
Two or many adsorption towers are accomplished: can alleviate air-flow and the impulsive force of adsorbent is made obtain in two adsorption towers evenly pressing the normal service life that to guarantee adsorbent again in the extremely short time.The difficult problem that this present just air separation plant technical field will be captured.
Summary of the invention:
Order of the present utility model provides the even pressure type adsorption tower in a kind of centre, its objective is such realization: at the bottom of adsorption tower mainly comprises body of the tower and flange, top cover, tower, bolt, air inlet that is arranged on down body of the tower and exhaust outlet, be arranged on the gas outlet of body of the tower; Middle part at middle body of the tower, the outside of body of the tower was provided with even depressor during the inner chamber of body of the tower in stretching in the diffuser section/gas collection pipeline section that is provided with air dispelling hole/gas collection hole, the pipeline section that is provided with flange were exposed at, and, at the outer surface of diffuser section/gas collection pipeline section, cover and be useful on the screen cloth of isolating adsorbent.
Owing to adopted such scheme, be provided with even depressor in the middle part of middle body of the tower, just can be connected with pipeline and valve with the adsorption tower that is provided with even depressor equally with high-pressure air source, in diffusing gas of adsorption tower inner chamber large tracts of land or gas collection, two or many of for mutual UNICOM are provided with even fast pressure of adsorption towers of even depressor equally; The inner chamber of body of the tower during the diffuser section that is provided with air dispelling hole stretched in just can be carried out the large tracts of land gas collection, carries out the diffusing gas of large tracts of land in the adsorption tower of low-pressure state in the adsorption tower of high pressure conditions, the alleviation air-flow is to the impulsive force of adsorbent; Outer surface in the diffuser section is coverd with screen cloth, just can isolate adsorbent, avoids adsorbent to run off.This technical scheme, relatively simple for structure, only be provided with even depressor, the impulsive force of the alleviation air-flow that is played, make the effect and the effect of aspect such as the even pressure of adsorption tower but very obvious fast, be the good behave of further improving the adsorption tower structure.
Description of drawings:
Accompanying drawing is middle even pressure type adsorption tower structural representation.
Among the figure: 1, bolt 2, gas outlet 3, the pipeline section 4 of giving vent to anger, flange 5, flange 6, screen cloth 7, even depressor 8, pipeline section 9, flange 10, diffuser section/gas collection pipeline section 11, air dispelling hole/gas collection hole 12, down at the bottom of body of the tower 13, air inlet 14, the tower 15, flange 16, air inlet pipeline section 17, bolt 18, flange 19, exhaust pipeline section 20, flange 21, exhaust outlet 22, middle body of the tower 23, body of the tower 24, go up body of the tower 25, top cover
The specific embodiment:
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Middle even pressure type adsorption tower, as shown in the figure:
Adsorption tower mainly comprises at the bottom of body of the tower 23 and flange 4/18, top cover 25, the tower 14, bolt 1/17, air inlet 13 that is arranged on down body of the tower 12 and exhaust outlet 21, be arranged on the gas outlet 2 of body of the tower 24.Wherein:
Be arranged on down the air inlet 13 of body of the tower 12, comprise air inlet pipeline section 16 and flange 15;
Be arranged on down the exhaust outlet 21 of body of the tower 12, comprise exhaust pipeline section 19 and flange 20;
Be arranged on the gas outlet 2 of body of the tower 24, comprise give vent to anger pipeline section 3 and flange 5.
14 usefulness bolts 17 are fixed on down flange 18 bottom surfaces of body of the tower 12 at the bottom of the tower.
In the middle part of middle body of the tower 22, the outside of body of the tower 24 was provided with even depressor 7 during the inner chamber of body of the tower 24 in stretching in the diffuser section/gas collection pipeline section 10 that is provided with air dispelling hole/gas collection hole 11, the pipeline section 8 that is provided with flange 9 were exposed at;
And,, cover and be useful on the screen cloth 6 of isolating adsorbent at the outer surface of diffuser section/gas collection pipeline section 10.
