The invention discloses an energy-saving marine carbon capture system, as shown in figure 1, comprising: absorption tower 3, desorption tower 5, first heat exchanger 4, cooler 6 and a plurality of pipelines and pumps. The main engine of the ship is used for providing power, the auxiliary engine is used for generating power for other equipment on the ship, and the main engine and the auxiliary engine are both diesel engines, so that a large amount of smoke is generated by the main engine cylinder sleeve 1 and the auxiliary engine cylinder sleeve 2, and especially the smoke generated by the main engine cylinder sleeve 1 is more, and the smoke forms a smoke stream 9. The flue gas is led to the absorption tower 3; the amine liquid in the absorption tower 3 absorbs carbon dioxide in the flue gas to form rich liquid; the residual gas is discharged from the top of the absorption tower 3; the rich liquid flow 7 passes through the main engine cylinder sleeve 1 and/or the auxiliary engine cylinder sleeve 2 and is heated to the temperature (about 80-125 ℃) required by desorption of carbon dioxide by the amine liquid after being used as a cylinder sleeve cooling medium to exchange heat with the cylinder sleeve, and then enters the desorption tower for desorption to form lean liquid. The rich liquid is used as a cylinder liner cooling medium for cooling the main engine cylinder liner 1 and the auxiliary engine cylinder liner 2, so that the heat of the cylinder liner is recycled, and the energy consumption of a carbon capture system is reduced.
Before entering the cylinder sleeve of the main engine and/or the auxiliary engine, the rich liquid firstly enters the first heat exchanger 4; the rich stream 7 and the lean stream 8 exchange heat within said first heat exchanger 4; the lean liquid sequentially passes through the first heat exchanger 4 and the cooler 6, and finally returns to the absorption tower 3. The first heat exchanger 4 may be used to achieve preheating of the rich liquid stream 7 and pre-cooling of the lean liquid stream 8, the cooler 6 being used to further cool the lean liquid to a temperature (about 10 c to 60 c) required for absorption of carbon dioxide by the amine liquid.
In some embodiments, the rich liquid may be split after being preheated by the first heat exchanger 4, and used for cooling the main machine leveling end 10. The rich liquid is recombined after cooling the main engine cylinder sleeve 1, the auxiliary engine cylinder sleeve 2 and the main engine flat end 10 respectively so as to utilize the heat of the main engine flat end 10.
In some embodiments, the carbon capture system further comprises a second heat exchanger 11, the second heat exchanger 11 is used for partially absorbing heat of the flue gas, and the rich liquid is heated for the third time, so that the temperature of the rich liquid is ensured to be heated to the desorption temperature. In the second heat exchanger 11, the inlet end of the rich liquid is communicated with the main engine cylinder sleeve 1 and/or the auxiliary engine cylinder sleeve 2 and the main engine horizontal end 10, and the outlet end is communicated with the desorption tower 5; the inlet end of the flue gas is communicated with the main engine cylinder sleeve 1 and/or the auxiliary engine cylinder sleeve 2, and the outlet end is communicated with the absorption tower 3.
Further, the carbon capturing system further comprises a first three-way valve 12, wherein the first three-way valve 12 divides the rich liquid flowing out of the cylinder sleeve into two streams, and one stream enters the second heat exchanger 11 to exchange heat with the flue gas again; the two rich liquids are combined and then enter a desorption tower 5. A flow control valve is also arranged on the pipeline where the second heat exchanger 11 is located so as to control the quantity of rich liquid exchanging heat with the flue gas, and the distribution proportion of the two rich liquids is adjusted so as to cope with the possibly occurring complex working conditions on the ship.
In some embodiments, the carbon capture system further comprises a second three-way valve 13 and a third three-way valve 14. The inlet and outlet of the absorption column 3 and the desorption column 5 also include control valves to control opening and closing. The lean solution enters the second three-way valve 13 before entering the absorption tower 3, and the rich solution enters the third three-way valve 14 before entering the desorption tower 5. One end of the second three-way valve 13 is communicated with the rich liquid outlet end of the absorption tower 3, one end of the third three-way valve 14 is communicated with the lean liquid outlet end of the desorption tower 5, one side of the second three-way valve 13, which is communicated with the rich liquid outlet end of the absorption tower 3, is closed under the condition that the carbon capturing system operates normally, and one side of the third three-way valve 14, which is communicated with the lean liquid outlet end of the desorption tower 5, is closed.
When the carbon capture system is in a starting state, the auxiliary machine is started in advance, and then a pump in the system is started, so that the amine liquid flows. At this time, the inlets and outlets of the absorption tower 3 and the desorption tower 5 are closed, and one side of the second three-way valve 13, which is communicated with the rich liquid outlet end of the absorption tower 3, is opened, and one side of the third three-way valve 14, which is communicated with the lean liquid outlet end of the desorption tower 5, is opened by adjusting the second three-way valve 13 and the third three-way valve 14; so that the amine liquid is circulated to the main engine cylinder sleeve 1 and the auxiliary engine cylinder sleeve 2 again without passing through the absorption tower 3 and the desorption tower 5. The cooler 6 also does not introduce cold streams and does not cool the amine liquid. The auxiliary cylinder sleeve 2 heats itself, and the continuous heating of the amine liquid is realized. The heat of the amine liquid can be transferred to the main engine cylinder sleeve 1, so that the main engine cylinder sleeve 1 is heated, after the main engine cylinder sleeve 1 is heated to a proper working temperature, the cooler 6 starts to introduce cold flow, and the amine liquid is cooled, so that the amine liquid is maintained in a temperature range suitable for the operation of the main engine cylinder sleeve 1. At this time, the operator may selectively adjust the second three-way valve 13 and the third three-way valve 14 such that one side of the second three-way valve 13, which communicates with the rich liquid outlet end of the absorption tower 3, is closed, one side of the third three-way valve 14, which communicates with the lean liquid outlet end of the desorption tower 5, is closed, and the control valves of the inlets and outlets of the absorption tower 3 and the desorption tower 5 are opened, so that carbon dioxide recovery is started.
When the carbon capturing system starts to stop, the host stops running, the inlets and outlets of the absorption tower 3 and the desorption tower 5 are closed, one side of the rich liquid outlet end of the absorption tower 3 is opened by the second three-way valve 13 which is communicated with the rich liquid outlet end of the absorption tower 3, and one side of the lean liquid outlet end of the desorption tower 5 is opened by the third three-way valve 14 which is communicated with the rich liquid outlet end of the desorption tower 5; so that the amine liquid is circulated to the main engine cylinder sleeve 1 and the auxiliary engine cylinder sleeve 2 again without passing through the absorption tower 3 and the desorption tower 5. After a certain period of time after the auxiliary machine is turned off, the cold flow to the cooler 6 is stopped and the pump in the carbon capture system is turned off.
In some embodiments, the ph=7 to 9 before the amine solution absorbs the flue gas by dilution because the metal is easily corroded under strong alkaline conditions. To reduce the corrosion of the amine liquid to the cylinder liner.
From the perspective of corrosion prevention, a protective layer can be covered on the surface of the cylinder sleeve. Further, the protective layer is a metal plating layer, and the metal is at least one of chromium, cobalt and nickel. The anti-corrosion effect can be further improved.
In some embodiments, the gas obtained after desorption in the desorption tower sequentially enters a compression device, a liquefaction device and a liquid carbon dioxide storage tank to finally finish capturing and storing carbon dioxide.
In summary, the invention takes the amine liquid as the cooling medium of the cylinder sleeve to directly absorb the heat of the cylinder sleeve, thereby utilizing the limited energy on the ship to the maximum extent and saving the energy. According to the invention, through setting the alkalinity of the amine liquid and the material of the cylinder sleeve, the condition that the amine liquid corrodes the cylinder sleeve is reduced to the greatest extent. According to the invention, the first three-way valve and the second heat exchanger are arranged, so that on one hand, the heat of the flue gas is further utilized, and on the other hand, the heat absorbed by the amine liquid of the carbon capture system is regulated, so that the complex working conditions possibly occurring on the ship are dealt with. According to the invention, the second three-way valve, the third three-way valve and the corresponding connecting pipelines are arranged, so that the carbon trapping system can be stably started and stopped.
While the present invention has been described in detail through the foregoing description of the preferred embodiment, it should be understood that the foregoing description is not to be considered as limiting the invention.
