Description
Technical Field
The present utility model relates to the field of capturing carbon dioxide from mixed exhaust gases, and to an improved means of absorption and regeneration of carbon dioxide adsorbents for capturing carbon dioxide from exhaust gases containing carbon dioxide, such as exhaust gases from combustion of carbonaceous materials or other carbon dioxide releasing reactions.
Background
Over the past centuries, the combustion of fossil fuels such as coal, natural gas and petroleum has increased, resulting in an increase in the concentration of carbon dioxide in the atmosphere. The data indicate that the total amount of carbon dioxide produced by world-wide fuel usage by 2010 has reached 306 billions of tons and by 2020 has broken through 340 billions of tons. From the simulation data, greenhouse effect has more potential to affect the earth climate. The reduction of carbon dioxide emitted to the atmosphere from the combustion of fossil fuels can be achieved by capturing and safely storing carbon dioxide emitted from thermal power plants and other fossil fuel burning plants. The captured carbon dioxide may be injected into the subsurface, such as an oil well, as pressure to enhance oil recovery, or injected into depleted oil and gas wells for deposition. Experiments show that carbon dioxide can be preserved underground for thousands of years and cannot be released into the atmosphere.
Capturing carbon dioxide in exhaust gas by means of adsorbents has been used in the prior art for decades, for example for removing carbon dioxide (and other acid gases) from natural gas produced in gas fields. The adsorbents used in the prior art are various basic aqueous solutions such as potassium carbonate, potassium bicarbonate and various amine solutions. The separation of carbon dioxide from the exhaust gas of a thermal power plant with an amine solution is a common treatment method.
These carbon dioxide capture solutions are typically liquid adsorbents with the mixed gas to be separated introduced into the absorber column from the bottom end. After the carbon dioxide of the exhaust gas in the absorption tower is captured (or acid gas is absorbed), the carbon dioxide (or other acid gas) is discharged out of the absorption tower together with the adsorbent. The adsorbent regeneration reaction is carried out in a regeneration tower and returned to the absorption tower. Regeneration of the amine solution is carried out by stripping in a regeneration column with steam generated in a reboiler at the bottom of the column. However, in the current process of capturing carbon dioxide by the carbon capturing technology, the carbon dioxide capturing efficiency is low.

Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings and technical schemes, but is not limited to the following examples.
Example 1
The structural schematic diagram is shown in fig. 1.
An apparatus for removing carbon dioxide from exhaust gas using a superparamagnetic carbon dioxide adsorbent particle. Exhaust gas enters through the exhaust gas duct 1. The exhaust gas entering through the exhaust gas conduit 1 is split in the three-way valve 2 and enters the turbulent adsorber 5 in the upper inlet conduit 3 and the lower inlet conduit 4. The turbulent bed adsorber 5 is filled with a carbon dioxide adsorbent. The exhaust gases introduced in the upper inlet duct 3 enter the sieve tray 6. The gas rises from bottom to top through the vertical duct 29, which ensures circulation of the adsorbent particles and thorough mixing of the adsorbent particles with the exhaust gas. The actual design of the turbulent bed adsorber will depend on the carbon dioxide capture specifications. The suspension of carbon dioxide-capturing particles is contacted with a carbon dioxide-containing exhaust gas. The reaction between the exhaust gas and the above-mentioned liquid suspension of particles is carried out in a turbulent adsorber, in which a large number of bubbles are produced. When the exhaust gas after carbon dioxide absorption escapes from the adsorber, it is released to the surrounding environment through the exhaust gas outlet 7, and a mist eliminator 8 is provided at the exhaust gas outlet 7 to prevent water mist from escaping from the apparatus together with the exhaust gas. Optionally, a cleaning device is required to ensure that no chemicals are discharged. The suspension of adsorbent particles is discharged through an adsorbent discharge pipe 9 and into an adsorbent tank 10. The suspension overflows from a low wall at one side of the adsorbent pool 10 and flows through a gap between the centrifugal separation screen drum 11 and the side of the liquid separation channel 13; an electromagnet 12 with a cambered surface is arranged on the surface of the centrifugal separation screen cylinder 11, so that superparamagnetic particles are stuck to the electromagnet when the centrifugal separation screen cylinder rotates, and liquid enters the recovery pipe 27 from the liquid separation channel 13 by gravity.
The arc of the arc surface of the electromagnet 12 is set to be only 1/3 of the circumference of the centrifugal separation screen cylinder. The pulsed direct current connected to the electromagnet 12 cooperates with the centrifugal separation screen cylinder so that superparamagnetic particles that are attracted by the electromagnet 12 when it rotates over the arc-shaped shield 26 will fall off the cylinder side walls and be collected by the conveyor belt.
These superparamagnetic particles are then introduced into a regeneration tower 16 (e.g. a spray tower), the particles are sprayed into the regeneration tower 16 by a solid spraying device 17, and the steam entering the bottom of the regeneration tower through a steam pipe 18 is reboiled by upward flow, at which time carbon dioxide is released from the adsorbent particles. The released carbon dioxide and steam are collected by the collecting pipe 19, and then the mixture of carbon dioxide and steam is cooled by entering the cooler 20, and is separated into carbon dioxide gas and liquid water in the condenser 21. Carbon dioxide is extracted in the flash tank through a collection pipe and then further processed before entering the plant outlet. Water is fed in condensate line 23 to reboiler 24 where it is heated to produce steam which is passed through steam line 18 to the regeneration column. The recovered particles are extracted from the particle recovery pipe 27 at the bottom of the regeneration tower, mixed with the amine liquid in the drain pipe 14, and then pumped out by the pump 25, and re-enter the turbulent bed adsorber 5. Water enters the recovery tube 27 by replenishing it through a makeup water line 28 after the pump 25.
In the apparatus shown, the suspension is recovered from the turbulent adsorber by a continuous flow rate, allowing the apparatus to be operated continuously. Batch operation is also possible, but requires multiple adsorbers to operate simultaneously.
