Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of bio-trickling filter filler spray structure as shown in Figure 1 to Figure 3, including spray column 4, spray liquid catch tray 3,
Shower tray component and wall stream cleaning ring 10；Wall stream cleaning ring 10 can collect the liquid gathered on spray inner wall of tower, the cleaning of wall stream
The through flow hole 11 of ring 10 is collected hole with the spray liquid in the upper surface of two-sided shower tray unit 2 and is coaxially distributed so that liquid collecting annular groove
Spray liquid in 12 can equably flow to spray straight tube 8, so as to continue to spray to bottom by spray apertures 9, effectively solve wall
The problem of gas and liquid can not be contacted fully with biology on filler in spray column 4 caused by flow phenomenon, and effective biomass is low.
Spray column 4 is separated into multiple independent spray cylinders by spray liquid catch tray, and shower tray component includes one side shower tray
Unit 1 and two-sided shower tray unit 2, one side shower tray unit 1 is positioned at the top of independent spray cylinder, two-sided shower tray unit 2
Positioned at the lower section of one side shower tray unit 1；Wall stream cleaning ring 10 is located at the top of two-sided shower tray unit 2.
One side shower tray unit 1 includes one side ring sparger and spray straight tube 8, and the both ends of spray straight tube 8 are located at one side spray
The inside of ring.Two-sided shower tray unit 2 includes two-sided ring sparger and spray straight tube 8, and the both ends of spray straight tube 8 are located at two-sided spray
The inside of ring.Spray straight tube 8 connects with inside one side ring sparger and two-sided ring sparger respectively.
The downside of spray straight tube 8 is provided with spray apertures 9, a diameter of 4mm~6mm of the spray apertures 9, preferably 5mm；Spray apertures
9 spacing is 150mm~250mm, preferably 200mm.
The upside of two-sided ring sparger is provided with spray liquid and collects hole, and the downside of two-sided ring sparger is provided with spray apertures 9；Spray liquid

The upside of wall stream cleaning ring 10 is provided with liquid collecting annular groove 12, and the bottom of liquid collecting annular groove 12 is provided with through flow hole 11.
8 a diameter of 20mm~40mm of straight tube is sprayed, the spacing of spray straight tube 8 is 200mm~800mm.Between spray straight tube 8
Spacing become larger from centre to surrounding, to weaken the problem of spray liquid radial distribution is uneven caused by wall flow phenomenon；
On the spray straight tube 8 being distributed on each height layer, spray apertures 9 are uniform-distribution with.
Shower tray component carries out Multi-layer sprinkling to filler, and the spacing of adjacent shower tray unit is 0.8m to 2m, is advantageous to give up
Gas is redistributed in filter tower is dripped, and increases the touch opportunity of waste gas and filler.The spacing of adjacent shower tray unit is from top to bottom
Uniformly reduce, can so ensure that bottom filler has the wetting of abundance, whole packing layer is maintained a uniform humidity.Root
Factually border service requirement, every one spray liquid catch tray 3 of several layers of settings, the spacing of adjacent spray liquid catch tray 3 arrives for 3m
7m.The inwall of spray liquid catch tray 3 and spray column 4 is fixed, and for collecting circulation fluid, then passes through the pipeline 5 on the outside of tower body
Be discharged into circulation liquid bath 6, avoid because in spray liquid dead microbial gradually increase and caused by filler block the problem of, while can also prevent
Only circulation fluid excessively washes away to spray column bottom packing layer.
Spray liquid is pumped into shower tray component by circulation liquid bath 6 successively.
It the above is only concrete application example of the present utility model, do not form any limit to the scope of protection of the utility model
System.All technical schemes formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
