The radial flow absorber is characterized in that the radial flow absorber consists of an end plate (1), an encloser (2), an absorbent (3), an external distribution cylinder (4), a flange (5), charging ports (6, 7), an outlet pipe (8), an internal distribution cylinder (9), an end cover (10), a middle distribution cylinder (11), a base plate (12), a tapered splitter (13), a support column (14), an inlet pipe (15), and a holding-down device (19); a plurality of concentric multihole distribution cylinders divide absorbent particles. In the absorber, gas flows through the absorber approximately in zigzag shape. The radial absorber has the characteristics of uniform gas distribution and small pressure drop, and is applicable for catching and recycling the gases with high output and light concentration.
Description
Technical field
The invention belongs to the gas separation field, specially refer to a kind of radial flow adsorber, be mainly used in the low CO of concentration in big flow gas such as the flue gas
2, SO
2Capture Deng gas.
Background technology
CO in the flue gas
2Concentration is lower, greatly about 8%～15%.System is to CO
2Capture rate to obtain CO when surpassing 90%
2Concentration surpasses 90% product gas, can adopt high pressure transformation adsorption process.But high pressure captures the CO in the flue gas
2Wasted big energy owing to the gas that nitrogen in the flue gas etc. is not needed capture carries out high compression, thereby increased operating cost, concentration is low more in the industrial tail gas, and the energy of waste is many more.Thereby to the CO in the industrial tail gas such as flue gas
2The absorber that captures will adopt a Rational structure, makes it also to have when handling high flow rate light concentration gas that pressure drop is little, the uniform characteristics of distribution of gas.Effect was also not relatively good when existing axial flow absorber was not very big in processing tolerance, but when handling atm number, not that to take to increase the absorber diameter be exactly to take to increase the measure of absorber height or the mode that both combine, this can cause respectively, and distribution of gas is uneven falls with very big pressure, all greatly reduces the usefulness of absorber.
Summary of the invention
The present invention seeks to solve the distribution of gas inequality and the very big pressure that exist when existing equipment is handled atm number and fall, greatly reduce the problem of the usefulness of absorber.
A kind of radial flow adsorber that is used for high flow rate light concentration gas trapping is made of end socket 1, shell 2, adsorbent 3, the outer tube 4 that distributes, flange 5, filler 6,7, outlet 8, inside distributor 9, end cap 10, middle distribution tube 11, base plate 12, conical baffle 13, support column 14, inlet tube 15, hold down gag 19.First end of end socket 1 sealing and second end and columnar absorber of shell 2 formations of sealing with end cap 10, the two ends of absorber have direct fluid to enter the inlet tube 15 of absorber and the outlet 8 that direct fluid is discharged absorber respectively, and end cap 10 is connected by flange or welding manner with shell 2.Inside distributor 9, outer tube 4 all concentric being welded on the base plate 12 that distribute, middle distribution tube 11 is welded on the end cap 10, and conical baffle 13 is welded on the base plate 12.Support column 14 is welded on base plate 12 and the end socket 1.The outer tube 4 that distributes, inside distributor 9, middle distribution tube 11 annular regions that are separated into the 21, the 22nd, the zone of filled with adsorbent 3.According to the needs of filled with adsorbent kind, the quantity of the tube that distributes can increase or reduce, thus corresponding increase or the minimizing that causes annular region quantity.16,17,18 expression air current flow directions.Annular region 20 is uniform districts of air inlet.The outside of inside distributor 9, outside distribute tube 4 the inboard and in distribute and be tied with the steel-wire screen of separating adsorbent on the inboard of tube 11 or the outside, each tube that distributes all has the aperture of varying number, but the hole on each distributes tube all is uniform percent opening difference, and the outer tube not perforate in the upper end cover certain distance H that distributes, H=30～200mm, the mass flow discrepancy that causes greatly owing to upper pressure is even to distribute so that proofread and correct, and the H=0 of inside distributor, middle distribution tube.The outer percent opening that distributes tube is 33%～45%, and the middle percent opening that distributes tube is 35～50%, and the percent opening of inside distributor is 5～20%.
Adsorbent filler the 6, the 7th is along 4-10 the hole that end cap 10 is circumferentially evenly opened.
Structure of the present invention makes pressure swing adsorption system have good distribution of gas when handling high flow rate light concentration gas and little pressure falls, and energy efficient improves absorber usefulness.
Gas flow mainly is entad Z-shaped flowing in the radial flow adsorber among the present invention, and adopts special even gas distribution mode, make gas evenly by and pressure drop ratio less, be suitable for handling high flow rate light concentration gas.

The specific embodiment
Referring to accompanying drawing, Fig. 1 has provided an absorber of the present invention, and absorber has 2, one on a shell and is roughly the end socket 1 that hemispherical head seals by one, and the end cap 10 of a plate shaped end plate closes.End socket 1 also comprises inlet tube 15.End cap 10 also comprises an outlet 8.End cap 10 also comprises the filler 6,7 that is used for importing and discharge in the inside of absorber adsorbent etc., and hold down gag 19 as shown in Figure 4.End cap 10 is connected by flange or welding manner with shell 2.
Middle part distribution tube is welded on the end cap 10, inside distributor 9, outer tube 4 all concentric being welded on the base plate 12 that distribute.Conical baffle also is welded on the base plate 12.The outside of inside distributor 9, outside distribute tube 4 the inboard and in distribute and be tied with the steel-wire screen of separating adsorbent on the inboard of tube 11, annular region 21,22 between the distribution tube defines the position of adsorbent, filler the 6, the 7th is along 8 holes that end casing is circumferentially evenly opened, what this hole defined adsorbent enters annular region 21,22, and go back the reserve part adsorbent in this filler 6,7 after in 21,22, filling it up with adsorbent, under the effect of hold down gag 19, can make 21,22 inner adsorbents of filling keep the jam-pack state.
The conical baffle 13 that is arranged on absorber bottom is used for guiding with arrow 17 represented working fluids and enters shell 2 and the outer long and narrow annular region 20 that distributes between the tube 4, as shown in arrow 17 then pass successively outside, in, inside distributor and along outlet 8 outflows.
Among Fig. 4, hold down gag 19 plays and a kind ofly compresses and make the adsorbent of annular region 21,22 middle and upper parts closely to contact with end cap 10 all the time in the filler 6,7, avoids the air-flow short circuit phenomenon that causes big hole to cause owing to reasons such as vibrations.
What Fig. 3 showed is, have interior, in, several annular regions 20,21,22,23 of surrounding of outer distribute tube (9,11,4) and shell 2, annular region the 20, the 23rd, the zone that direct fluid flows, can put into different adsorbents successively in the annular region 21,22, handle different fluids, as putting into activated alumina, 13X zeolite, silica gel etc.The annular region 20 that shows among Fig. 3 is 6 with the ratio of the cross section of annular region 23.
The present invention has realized flowing by the Z-shaped of absorber.The air current flow direction is with just in time opposite shown in the arrow 17 when the absorber desorption process.
