본 발명은 3차원 다공체로 된 복합형 고체 고이온전도체를 이용한 리튬황배터리에 관한 것으로, 용융온도 이상의 고온(120℃ 이상)에서 유동성을 가지게 되는 유황이 배터리 셀 전극 외부로 누설되는 것을 방지할 수 있는 복합형 고체 고이온전도체를 이용하여 상온뿐만 아니라 고온에서도 작동가능한 리튬황배터리를 구현함으로써 성능 저하 없이 배터리를 사용함은 물론 오히려 고온에서의 이온전도도가 증가되어 배터리의 출력성능을 향상하고자 한다.
Abstract:
PURPOSE: A device for capturing carbon dioxide in exhaust gas is provided to reduce renewable energy required for recycling an absorption solution which absorbs carbon dioxide from regeneration towers and to reduce collection cost of total carbon dioxide. CONSTITUTION: A device for capturing carbon dioxide in exhaust gas comprises absorption towers (10); regeneration towers (20); a first heat exchanger (31); a second heat exchanger (32): and a dehydration device (100). The absorption towers absorb carbon dioxide in the exhaust gas into an absorption solution. The regeneration towers heat up the absorption solution which absorb carbon dioxide and recycles the same. The first and second heat exchangers are installed on a line between the regeneration towers and the absorption towers and perform heat exchange between the recycled absorption solution and the carbon dioxide absorption solution for two times. The dehydration device is installed on a line between the first and second heat exchangers and absorbs moisture inside the absorption solution. The dehydration towers control the moisture concentration inside the absorption solution before being supplied to the absorption towers to be maintained within a set range.

PURPOSE: Equipment for trapping carbon dioxide is provided to save recycling energy by 20% or more and to increase operation stability of a CO2 absorbing process by maintaining water content over a specific amount or more. CONSTITUTION: Equipment for trapping carbon dioxide comprises a absorbing tower(10), a recycling tower(13), and a heat exchanger(12). The absorbing tower absorbs CO2 in exhaust gas, into an absorbing solution. The recycling tower heats and recycles the absorbing solution with CO2 exhausted from the absorbing tower. The heat exchanger is installed in a line(18a) between the absorbing tower and recycling tower and conducts heat exchange. A dehydrating apparatus(17) absorbing water in CO2 absorbing solution and constantly maintains the concentration range of water in the CO2 absorbing solution. The dehydration installed in the line is installed in front or back of the heat exchanger.
Abstract:
PURPOSE: A regenerator for carbon dioxide absorbing liquids is provided to save energy by controlling the preheating of absorbents and the cooling of pressure carbon dioxide under a uniform condition. CONSTITUTION: A regenerator for carbon dioxide absorbing liquids comprises a first storage tank(110), a regeneration tower, a separation drum(160), a multi-stage compressor(170), heat exchangers, a temperature sensor(130), and a flow meter(120). The first storage tank stores the carbon dioxide absorbing liquids. The regeneration tower generates regenerated absorbents by heating absorbents and vitrifying carbon dioxide. The separation drum separates the vitrified carbon dioxide. The compressor compresses the separated carbon dioxide. The heat exchangers heat-exchange the compressed carbon dioxide with the absorbents discharged from the first storage tank. The temperature sensor detects the temperature of the absorbents after heat exchanging. The flow meter controls a flow rate of the absorbents passing through the heat exchangers according to the detected temperature of the absorbents.
