Specific implementation mode
Specific embodiment of the utility model is given below.Specific embodiment is only used for being further described this practicality newly
Type does not limit the application scope of the claims.
The utility model provides a kind of drain horizontal bore column plate (referring to Fig. 1-3, abbreviation column plate), including tower casing 1,
It is characterized in that the column plate further includes down-flow plate 3, bottom plate 5, draining plate weir 6, draining plate 7, liquid barrier connecting plate 8 and liquid barrier 9；Institute
It states 5 level of bottom plate and is fixedly mounted on 1 inner wall of tower casing, plate hole 11 is provided on bottom plate 5；The down-flow plate 3 is fixed on vertically in tower casing 1
Wall；Down-flow plate 3 surrounds downspout 2 with tower casing 1；The draining plate 7 is seamlessly connected with down-flow plate 3；Between draining plate 7 and bottom plate 5
There is bottom gap 4；There are gradients between draining plate 7 and bottom plate 5；There is draining plate in position corresponding with plate hole 11 on the draining plate 7
Trepanning 10；The size of draining plate trepanning 10 is more than the size of plate hole 11；7 upper surface of draining plate is fixed on the draining plate weir 6, is enclosed
In the periphery of draining plate trepanning 10, prevents the liquid phase sprayed from draining plate trepanning 10 from returning to draining plate trepanning 10, drop can only be passed through
Liquid pipe 2 goes to descending trays；The both ends of the liquid barrier 9 are connect by liquid barrier connecting plate 8 with bottom plate 5；Liquid barrier 9 and bottom plate
There are gradients between 5；
Draining plate 7 is located at 5 top of bottom plate, and liquid barrier 9 is located at 5 lower part of bottom plate；
The liquid barrier 9 divides parallel and be staggered for two rows, has gap between two rows of liquid barriers 9；Lower gear liquid
9 position of plate is corresponding with plate hole 11；
Preferably, liquid barrier 9 is V-type, and upper row's liquid barrier is lower V-type, and lower row's liquid barrier is upper V-type；Liquid barrier 9 and bottom plate
There are gradients between 5, that is, the position for being located at 3 bottom end of neighbouring upper layer column plate down-flow plate is higher than neighbouring this layer of 3 top of column plate down-flow plate
Position, the quantity of upper row's liquid barrier is one more than lower row's liquid barrier；Lower row's liquid barrier is 5 in the present embodiment, upper gear liquid
Plate is 6；The distance between the summit of upper row's liquid barrier and the peak base of lower row's liquid barrier are 50~200mm, preferably 90mm；
