2Capture when adopting varies method decarbonization process,, prevent the coal-fired flue-gas CO of varies solution foaming, bias current in order to improve the decarburization capacity of varies
2The absorption reaction tower.
Two, background technology
At a large amount of CO of discharging every day in the oil field power plant for self-supply coal-burning boiler
2, promptly polluted environment, wasted resource again.Adopt the CO in the varies method decarbonization process capture coal burning boiler
2, and with CO
2Be used for the displacement of reservoir oil after the liquefaction, can improve oil recovery factor 10-30%, and 60-70%CO is arranged
2Seal up for safekeeping underground, reach the multiple target of energy-saving and emission-reduction, exhaust-gas resource utilization.Varies method decarbonization process system comprises CO
2Absorption process and CO
2Regenerative process, CO
2Vital part in the absorption process decarburization operation is directly determining decarburization efficient, and this process is mainly finished in the absorption tower, and the main effect on absorption tower is exactly: 1. remove many CO as far as possible
22. anti-anti-avulsion varies solution foaming, bias current.
Three, summary of the invention
The purpose of this utility model provides a kind of coal-fired flue-gas CO
2The absorption reaction tower can make CO by the absorption tower
2Absorptivity reaches more than 99.5%, avoids varies solution foaming, bias current phenomenon, simplifies decarbonization process, reduces production decarburization cost, improves decarburization efficient.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of absorption tower housing, gas outlet, mist extractor, shower, gland, corrugated plate packing, ring packing, screen, air inlet pipe distributor, rich solution pipe, blow-off pipe, skirt, it is characterized in that the middle part is provided with inlet chamber under the absorption tower, be provided with the air inlet pipe distributor in the bottom of inlet chamber, be provided with the rich solution chamber in air inlet pipe distributor bottom, upwards be provided with screen, corrugated plate packing, dividing plate from the air inlet pipe distributor by preface, cushion chamber, screen, ring packing, dividing plate, the filter net type mist eliminator of spray chamber and bottom, end socket top; Be provided with the gas outlet at the upper cover top, be provided with the horn spray thrower under spraying in the spray chamber, the shower that is communicated with spray thrower stretches out from one side body middle part, spray chamber; On the lower case of rich solution chamber, be provided with the rich solution outlet; Be provided with blow-off pipe in the low head bottom; Below low head, be provided with skirt.
The coal-fired flue-gas CO that the utility model is designed
2Absorption reaction tower absorption tower has the following advantages:

Four, description of drawings
Fig. 1-structural representation of the present utility model.
Sequence number explanation among the figure:
1, absorption tower housing 2, gas outlet 3, mist eliminator 4, shower 5, dividing plate 6, ring packing 7, screen 8, ripple packing 9, air inlet pipe distributor, 10, rich solution outlet 11, blow-off pipe 12, skirt
Five, embodiment
For further disclosing the technical solution of the utility model,, elaborate by embodiment below in conjunction with Figure of description;
The utility model relates to a kind of coal-fired flue-gas CO that is used for
2The absorption reaction tower, by absorption tower housing 1, gas outlet 2, mist eliminator 3, shower 4, dividing plate 5, ring packing 6, screen 7, corrugated plate packing 8, air inlet pipe distributor 9, rich solution pipe 10, blow-off pipe 11, skirt 12 are formed, and it is characterized in that at coal-fired flue-gas CO
2Absorption reaction tower lower side is provided with air inlet pipe distributor 10 and puts in enclosure interior, becomes cross, and tower middle part filler is a corrugated plate packing, and the middle and upper part is a ring packing, and bubbler is a trumpet type, and mist eliminator is equipped with in the lower end, gas outlet.Coal-fired flue-gas CO
2Its operation principle of absorption reaction tower and the course of work are: coal-fired flue-gas enters housing by the air inlet pipe distributor 9 of lower housing portion, with varies solution counter current contacting, through process corrugated plate packing district 8, enter ring packing district 6 again, coal-fired flue-gas after the decarburization is after mist extractor 3 removes varies liquid drop, 2 enter atmosphere from the gas outlet, varies solution sprays into from the upper end, absorption tower through shower 4, flow out from lower end, absorption tower rich solution outlet 10, more favourable and the gas-liquid mass transfer of the ring packing on top is also avoided solution foaming and bias current, and corrugated plate packing district in middle part has more strengthened the efficient mass transfer between gas-liquid, improved absorption efficiency, the sparge pipe flue, it is uniform more to help liquid, air inlet pipe distributor across, help even gas distribution, avoid bias current, crossfire.
