Specific embodiment
As shown in Figure 1 to Figure 2, the invention mainly comprises bottom plate 1, first baffle 2 and second baffles 3, with reference to the accompanying drawing
The present invention will be described in detail.
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
Passway 5 is formed between second baffle and end plate, in the second partition of the rightmost side, per two adjacent second baffles between and
Gas vent 7 is then formed between second baffle and end plate.Internal gas passageways 6 are formed between first partition and second partition.This
Sample, gas enter in internal gas passageways through gas access first, then enter another adjacent internal gas through passway
In channel.The acquisition of second partition upper channel mouth or gas vent, obtained except through interval setting second baffle it is outer, can be with
It is obtained by way of borehole on a monolith second partition.
As shown in figure 3, gas enters between first layer first partition and first layer second partition from left side through gas access
In the internal gas passageways surrounded, then entered through passway in another adjacent internal gas passageways, subsequent gas according to
It is secondary to be moved from left to right through passway, internal gas passageways, most removed afterwards through gas vent.
The quantity of first baffle in first partition can be four, at this time the first baffle length of the top and bottom
For 5mm, the length of two intermediate first baffles is 8mm, and the spacing between every two adjacent second baffles is 2mm.Second
The quantity of second baffle in partition is then three, and second baffle length is 8mm, between two adjacent second baffles
Away from and second baffle it is equal with the distance between end plate and be 2mm.
The considerations of for overall structural strength and processing, the horizontal distance between first partition and second partition are 4mm.
The present invention is improved in the structure of straight channel, and to be staggered is added by the inside in straight channel
One, the method for second baffle enables gas when entering anode flow channel due to the effect for the first, second baffle being staggered
