Four shunting pipelines 511 are respectively connected with four groups of gas detection devices, so that the four groups of gas detection devices can sequentially and alternately detect waste gas, and because each group of gas detection devices detects waste gas and needs a certain time, the four shunting pipelines 511 sequentially receive waste gas detection samples newly conveyed in turn, so that the waste gas detection can be continuously performed, and the burden of each group of gas detection devices is also reduced.
Because the special design of first box body 510 and second box body 520 is adopted in reposition of redundant personnel group building, waste gas flows through the clearance between first box body 510 and the second box body 520, the waste gas of being more convenient for is fully dispersed in first box body 510, has improved the homogeneity and the smoothness nature of gas reposition of redundant personnel, has reduced the unbalance nature of local atmospheric pressure effectively.
In addition, above layer upon layer box structure design for the structure is compacter, and the volume is littleer, and it is more convenient to use the installation, and third driver 532's work load is also littleer.
In summary, the carbon dioxide comprehensive utilization, trapping and recovery system 1000 provided by the embodiment of the invention can be combined with the conventional exhaust passage 100, and is suitable for transforming the conventional exhaust passage 100, so that the carbon dioxide in the waste gas can be conveniently trapped and recovered, and the convenience for recovering the carbon dioxide is improved; the implementation is convenient, and the modification cost of the traditional exhaust passage 100 is lower.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
