Description
First, technical field
The present invention relates to a kind of filler on-line cleaning device, and in particular to a kind of on-line cleaning of bio-trickling tower packing.
2nd, background technology
With the operation of bio-trickling filter, biologic packing material surface strain biofilm is more and more, aging and the thalline product die
Tire out on filler surface, or even block filler.In order to improve the blockage problem of filler, method main at present is that artificial unloading is filled out
Material, is reloaded into packed tower, but there are many deficiencies for this method after to be cleaned, it is impossible to meet production needs, existing deficiency
Place is as follows：
(1) unloading and cleaning difficulty are big, and the filler layer thickness in bio-trickling filter is generally at 2 meters or so, after filler blocks
There is more sludge, its weight greatly increases, and in uninstall process, wet and slippery and soft filler makes bio-trickling filter internal work
Bad environments, it is necessary to larger working face, more artificial, the substantial amounts of clear water of consumption in the cleaning process after filler unloading,
The unloading and cleaning of filler of a variety of conditions all limit values.
(2) stop cleaning, existing 10000m are needed3Inside the bio-trickling filter of/h treating capacities, all there is about 30~40m3Life
Thing filler, completes from the cleaning that is unloaded to of filler, at least needs 2 day time, during which bio-trickling filter must be out of service, seriously
Influence the normal operation of bio-trickling filter.
(3) biological inoculum loss is big, and in the artificial cleaning process of filler, the strain adhered on filler is largely all lost in
, after being again loaded into bio-trickling filter, since strain loss is more, just bio-trickling filter need to can be made normally to transport after Spawn incubation
OK, the normal operation of bio-trickling filter is influenced.
(4) clean of high cost, need to use substantial amounts of manpower and materials, and a large amount of cleaning sullages of generation in cleaning process, using compared with
Long time, fund cost and time cost are all higher.
(5) there is loss in filler, and bio-trickling inner-tower filling material has Pall ring filler, bead biologic packing material and Raschig ring etc.,
During unloading and cleaning, inevitably there are the damage of filler.
3rd, the content of the invention
It is an object of the invention to provide a kind of bio-trickling filter on-line cleaning device, make filler in bio-trickling filter not
Unloading need to be passed through, by way of on-line cleaning, you can solve the problems, such as filler congestion, can be widely applied to bio-trickling filter
The cleaning of interior filler.
The present invention is achieved through the following technical solutions：
A kind of bio-trickling filter on-line cleaning device of the present invention, structure type are：It is evenly arranged in packing layer some perpendicular
To Cleaning pipes, some cleaning sprayers are distributed in Cleaning pipes, cleaning sprayer injection direction and horizontal plane are in 45° angle, are being cleaned
The entrance access compressed air of pipeline, compressed air enters Cleaning pipes by gas pulses generator, Cleaning pipes with
Motor-driven valve is set on gas pipeline, and motor-driven valve and gas impulse generator are controlled by PLC controller, the bio-trickling filter bottom of box
If drainpipe, motor-driven valve is set, motor-driven valve is controlled by PLC controller on drainpipe.
Ejected wash water passes through cleaning by the Cleaning pipes, and the pulse gas mixing that gas impulse generator produces
During nozzle, very strong jet power and multifrequency Sasser are produced, by PLC controller, can adjust cleaning water and pulse strength, it is right
Filler carries out the flushing of varying strength, and the thalline of aging and death can be gone initial stage due to poor adhesive force in flushing on filler
Remove, by setting the parameter of PLC controller, optimally filler can be cleaned.Waste water after flushing enters biology
Filter tower bottom is dripped, passes through discharged.
The cleaning sprayer is evenly arranged in the different depth of packing layer, ensures that cleaning without dead angle, is filled out according to different
Material selects different nozzles, meets the needs of different types of bio-trickling filter.
The beneficial effects of the invention are as follows：The present invention compared with conventional clean mode, traditional bio-trickling tower packing it is clear
Wash that there are problems with：Filler unloads and cleaning difficulty is big, need stop cleaning, biological inoculum loss is big, cleans of high cost, filler
There are loss；The present invention realizes the on-line cleaning of filler：Filler is not required to out of drop filter tower in unloading, cleaning process without stopping
The operation of bio-trickling filter, by controlling scavenging period and cleaning strength to control remaining strain amount on filler, being pulsed using air water
The mode of flushing reduces the usage amount of flushing water, avoids the damage of filler in uninstall process, and benefit of the invention saves significantly
The about cleaning cost of filler, improves the efficiency of filler cleaning, realizes the automation of filler cleaning.
