Specific embodiment
As shown in Figure 1 to Figure 2, the utility model mainly includes bottom plate 1, first baffle 2 and second baffle 3, below with reference to
The utility model is described in detail in attached drawing.
As shown in Figure 1 and Figure 2, bottom plate 1 is that " [upper and lower ends of the plate structure of " shape, bottom plate are end plate 8, in two end plates
Between be equipped with left and right settings multilayer first partition, every layer of first partition includes the multiple first baffles set gradually from top to bottom
2, first baffle is collinearly arranged, and wherein two first baffles of the top and bottom are fixedly connected with end plate, and per adjacent
Gas access 4 is formed between two first baffles, the width of multiple gas accesses is equal.The acquisition of gas access except through
Except interval setting first baffle, it can also be obtained by way of the borehole in a monolith first partition.
Second partition is equipped between every two layers adjacent of first partition, second partition includes setting gradually from top to bottom
Multiple second baffles 3, the quantity of second baffle is identical as the quantity of the gas access in first partition in second partition, and second
Gas access in baffle and first partition corresponds, i.e., the gas entered through gas access is blocked by second baffle first,
Then it moves up and down.In addition to one layer of second partition of the rightmost side, in second partition per between two adjacent second baffles and
