Technical Field

The utility model relates to a carbon dioxide recovery plant technical field is planted to the flue gas, concretely relates to retrieve purification device of carbon dioxide.

Background

Boiler combustion generally accompanies with the production of flue gas, and this type of flue gas generally discharges to the atmosphere after handling, but this kind of mode exists to the insufficient problem of carbon dioxide in the flue gas utilization, and to the recycle mode of carbon dioxide in the flue gas, prior art has involved steps such as washing, absorption, analysis, purification, and the current purification device has the problem of mixing inhomogeneous, purification effect is not high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, to the not enough of existence among the above-mentioned background art, purify effectual purification device to carbon dioxide.

In order to achieve the above object, the utility model relates to a retrieve purification device of carbon dioxide has adopted following technical scheme:

the utility model provides a retrieve purification device of carbon dioxide, includes purification jar and pipe structure, purification jar upper end is provided with the outlet duct, purification jar upper portion still is provided with the feed liquor pipe, purification jar lower extreme is provided with the drain pipe, pipe structure is located purification jar lower part, pipe structure is including arranging purification jar outside outer tube in and arranging purification jar inside inner tube in, the inner tube is connected through being located the outside connector of purification jar with the outer tube, the outer tube is including the kink that upwards buckles the setting, the kink is connected with the intake pipe, a plurality of through-holes have been seted up along its length direction to the inner tube, and a plurality of through-holes are from being close to outer tube one side and keeping away from outer tube one side and gradually big setting, still be equipped with agitating unit in the purification jar.

The utility model relates to a further improvement part of purification device of retrieving carbon dioxide lies in, the kink is provided with the level gauge.

The utility model relates to a retrieve purification device of carbon dioxide's further improvement part lies in, the kink with be provided with the second connector between the intake pipe, be provided with one-way pneumatic valve in the second connector.

The utility model relates to a retrieve purification device of carbon dioxide's further improvement part lies in, equally divide on intake pipe, the kink of second connector both sides and do not be provided with ooff valve.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses set up the pipe structure for carbon dioxide gets into the pipe and just begins to contact with the sodium bicarbonate solution in pipe and the purification jar, gets rid of the impurity in the carbon dioxide gas, and mixed reaction time extension has guaranteed better purification effect, and simultaneously, the through-hole of equidimension not also makes the sodium bicarbonate solution in the mixed liquid ability relatively even and the purification jar in the outer tube mix on the inner tube, realizes the relatively even of mixing, and then reduces the stirring number of times, has improved the speed of purification.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure: 1 purification jar, 2 outlet ducts, 3 feed liquor pipes, 4 drain pipes, 5 outer tubes, 6 inner tubes, 7 connectors, 8 kinks, 9 level gauges, 10 intake pipes, 11 second connectors, 12 one-way air valves, 13 valves, 14 agitating unit.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

As shown in fig. 1, a retrieve purification device of carbon dioxide, including purification jar 1 and pipe structure, purification jar upper end is provided with outlet duct 2, purification jar upper portion still is provided with feed liquor pipe 3, purification jar lower extreme is provided with drain pipe 4, pipe structure is located purification jar lower part, pipe structure is including arranging purification jar outside outer tube 5 in and arranging purification jar inside inner tube 6 in, the inner tube is connected through being located purification jar outside connector 7 with the outer tube, the outer tube is including the kink 8 that upwards buckles and set up, the kink is connected with intake pipe 10, a plurality of through-holes have been seted up along its length direction to the inner tube, and a plurality of through-holes are from being close to outer tube one side to keeping away from outer tube one side and gradually big setting, still be equipped with agitating unit 14 in the purification jar. Further, the bending part is provided with a liquid level meter 9.

Further, a second connector 11 is arranged between the bending part 8 and the air inlet pipe 10, and a one-way air valve 12 is arranged in the second connector. The second connector is convenient for maintenance and replacement of the one-way air valve.

Furthermore, the air inlet pipes and the bending parts on two sides of the second connector are respectively provided with a switch valve 13. The setting of switch valve further controls the flow of carbon dioxide gas, and the controllability is stronger.

The utility model discloses a theory of operation does: add sodium bicarbonate solution in to the purification jar through the feed liquor pipe, at this moment, sodium bicarbonate solution can see through in inner tube to the kink, the feed liquor condition can be observed to the level gauge, later open switch valve, carbon dioxide gas gets into, mix the contact with sodium bicarbonate solution earlier in the outer tube, realize the sulfur dioxide in to the gas, hydrogen chloride etc. absorb, the reentrant inner tube, mix in the purification jar, because the existence of through-hole on inner tube and the inner tube, can also realize the even of mixing relatively in the purification jar, the whole effect that reaches the intensive mixing purification of stirring device's stirring, carbon dioxide gas after the purification at last is collected from outlet duct discharge. When the pipe structure needs to be cleaned, the pipe structure can be simply disassembled, so that the pipe structure is convenient to clean, and a better purification effect is ensured.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
