Abstract
The utility model discloses a kind of high efficiency gravity concentration tower, tower body including inner hollow and setting, one-level swash plate, two level swash plate, water inlet water distributor, supernatant return duct and precipitating sludge discharge pipe, the one-level swash plate is arranged at the middle and upper part in tower body, two level swash plate is arranged at the middle and lower part in tower body, water inlet water distributor is communicated in the tower body pars intermedia between one-level swash plate and two level swash plate to be sent into second pond sludge, supernatant return duct is communicated in the tower body top above one-level swash plate to reclaim supernatant, precipitating sludge discharge pipe is communicated in the tower body bottom below two level swash plate to exclude thickened sludge, so as to realize primary second pond excess sludge after the equipment, gravity concentration effect can be largely realized in short time.
Description
Technical field
Sludge disposal technology is the utility model is related to, especially a kind of high efficiency gravity concentration tower.
Background technology
Sludge condensation is the basis of sludge treatment technique, sludge condensation by reducing sludge interstitial water, reducing sludge volume,
So as to reduce the processing pressure of the techniques such as follow-up sludge digestion, dehydration.Sludge condensation generally use physical treatment method, main bag
Gravity concentration method, floatation thickening method, mechanical thickening method are included, at present, it is dirty to turn into current cities and towns because of economic sexual clorminance for gravity concentration method
The sludge condensation technique of water treatment plant's main flow, but the problem of concentrated effect difference in application process be present, it need to be improved.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of gravity concentration tower, realize that primary two is heavy
Pond excess sludge concentrates in the high efficiency gravity that gravity concentration effect after the equipment, can be largely realized in the short time
Tower.
The technical solution adopted in the utility model is：
A kind of high efficiency gravity concentration tower, including inner hollow and erect tower body, one-level swash plate, two level swash plate, enter water cloth
Water pipe, supernatant return duct and precipitating sludge discharge pipe, the one-level swash plate are arranged at the middle and upper part in tower body, and two level swash plate is set
The middle and lower part being placed in tower body, water inlet water distributor are communicated in the tower body pars intermedia between one-level swash plate and two level swash plate to be sent into
Second pond sludge, supernatant return duct are communicated in the tower body top above one-level swash plate to reclaim supernatant, precipitating sludge row
Outlet pipe is communicated in the tower body bottom below two level swash plate to exclude thickened sludge.
Further, barometric pipe is additionally provided with compensation tower inside and outside air pressure at the top of the tower body.
Wherein, the one-level swash plate is all made up of with two level swash plate some parallel swash plates, and one-level swash plate and two level are oblique
Plate is set in parallel in tower body.
The beneficial effects of the utility model：The utility model high efficiency gravity concentration tower is direct to the aerobic excess sludge of second pond
Gravity concentration is carried out, after reaching appropriate aqueous rate, enters back into aftertreatment systems.Aerobic excess sludge enters water distribution system in tower
Afterwards, slowly rise under hydraulic action, bulky grain thing gradually sinks, and after multilayer incline-plate, the increase of waterpower stroke, improves surplus
Remaining sludge settling efficiency, and then short time, efficient concentrated effect.
Brief description of the drawings
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the utility model high efficiency gravity concentration tower.
Embodiment
As shown in figure 1, a kind of high efficiency gravity concentration tower of the present utility model, including inner hollow and the tower body 1, one of setting
The main members such as level swash plate 2, two level swash plate 3, water inlet water distributor 4, supernatant return duct 5 and precipitating sludge discharge pipe 6.
Wherein, the one-level swash plate 2 is arranged at the middle and upper part in tower body 1, and two level swash plate 3 is arranged at the middle and lower part in tower body 1,
Water inlet water distributor 4 is communicated in the pars intermedia of tower body 1 between one-level swash plate 2 and two level swash plate 3 to be sent into second pond sludge, supernatant
Liquid return duct 5 is communicated in the top of tower body 1 above one-level swash plate 2 to reclaim supernatant, and precipitating sludge discharge pipe 6 is communicated in
The bottom of tower body 1 of the lower section of two level swash plate 3 is to exclude thickened sludge.
Its operation principle is：The second pond aerobic sludge of moisture content 99% enters water distribution system in tower from water inlet water distributor 4
Afterwards, slowly rise under hydraulic action, bulky grain thing gradually sinks, and after multilayer incline-plate, one-level swash plate 2 prevents bulky grain thing
Continue to rise and supernatant return duct 5 just can reclaim supernatant, two level swash plate 3 further makes the increase of waterpower stroke, improves
Excess sludge settling efficiency, and then short time, efficient concentrated effect, finally give the dense of moisture content 92%~95%
Contracting sludge is discharged from precipitating sludge discharge pipe 6, to enter back into aftertreatment systems.
As the further optimization of the technical program, the top of tower body 1 is additionally provided with barometric pipe 7 to balance tower body
1 inner and outer air pressure, carried out so as to which sludge condensation process is more uniformly quick.
Wherein, the one-level swash plate 2 is all made up of with two level swash plate 3 some parallel swash plates, and one-level swash plate 2 and two level
Swash plate 3 is set in parallel in tower body 1, and specific swash plate number can be appropriately arranged with according to factors such as tower body size and thickening efficiencies.
Preferred embodiments of the present utility model are the foregoing is only, the utility model is not limited to above-mentioned embodiment party
Formula, if with essentially identical means realize the technical scheme of the utility model purpose belong to the scope of protection of the utility model it
It is interior.
