Technical field
The utility model relates to a kind of flusher, and what be specifically related to is a kind of flusher of the swash plate/tube settler for cleaning water conservancy and engineering of water treatment.
Background technology
Precipitation is the important step of mud-water separation in the water treatment technology, its operation conditions directly affects effluent quality, traditional horizontal sedimentation tank advantage is simple structure, safe and reliable, shortcoming is that floor space is large, treatment effeciency is low, wants to reduce the length that the turbidity of filtering front water will strengthen sedimentation basin significantly.And this and human social theory are opposed.
The appearance of shallow pool theory makes sedimentation that significant progress arranged, and swash plate, inclined tube are referred to as shallow pond sedimentation basin, and it is based upon on this principle basis just.Be provided with a desirable sedimentation basin, cellar for storing things, pond V, surface area A, the long L in pond, wide=B, height=H processes water yield Q, time of staying t, sinking speed U0.V=Qt then, H=Uot, Q=Uot/H=U0A.By shallow pond precipitation principle as can be known: deposition efficiency only is the function of sedimentation basin surface area, and irrelevant with the depth of water.When the sedimentation basin volume was definite value, pond more shallow then A value was larger, and deposition efficiency is higher.So, if with sedimentation basin by highly being divided into the n layer, namely be divided into n and highly be the shallow layer settling unit of h=H/n, under the constant condition of Q, the sedimentation degree of depth of particle is reduced to H/n by H, the heavy fast scope of the particle that then can be completely removed in the sedimentation basin expands u U0/n to by original u U0, and minute rate that can be removed in the particle of heavy fast u＜U0 also increases to nu/U0 by u/U0, thereby makes this sedimentation basin suspended particulate clearance increase n than originally doubly.Obviously, the shallow-layer number of separation is more, and clearance is corresponding raising also.Can be made into swash plate or tube settler by this principle.
Placement angle is that (about 25～40 millimeters of inclined tube caliber, length is 800～1000 millimeters for 60 ° inclined tube or swash plate in the settling zone of sedimentation basin.About 100 millimeters of swash plate spacing).Because the settling zone is divided into many districts, desilting area and deposition efficiency significantly increase; Simultaneously, sink to mud on the pipe end or the plate face by the gravity settling zone that slips away.
Tube settler refers to be provided with the sedimentation basin of inclined tube in the settling zone.The parallel pipe or the parallelpiped (sometimes can utilize the honeycomb filler) that utilize in the settling zone of flat flow or vertical sedimentation basin are divided into a series of shallow layer precipitating layers, and processed and heavy mud sedimentation is mutually motion and separating in each precipitation shallow-layer.Be divided into contrary (different) to stream, three kinds of different separate modes of concurrent and reverse flow according to its mutual direction of motion.(or in parallel pipe) is equivalent to a very shallow sedimentation basin between per two inclined paralled plates.
Adopt the advantage of swash plate (inclined tube) sedimentation basin to be:
Utilize lamina flow principle, effectively utilized the pond dark, increased effective desilting area, improved the disposal ability of sedimentation basin;
Shorten the particles settling distance, thereby shortened the sedimentation time;
Increase the desilting area of sedimentation basin, thereby improved treatment effeciency.The mistake flow rate of this type sedimentation basin can reach 36m3/(m2.h), exceed 7-10 doubly than the disposal ability of general sedimentation basin, be a kind of new and effective settling apparatus.
Sewage is in this phase process process, and being deposited in the plant equipment that the mud of inclined tube (plate) sedimentation basin bottom adopts is steel wire rope pull sludge scraper, realizes the mud of scraping of straight reciprocating motion.
But the common inclined-tube sedimentation basin has again easy deposition, surface easily to grow algae and the perforation problems such as spoil disposal is not smooth.Need the flushing of regularly clear pond, reduction causes clogging because of the biomembrane overgrowing.And this stopping production of need to cutting off the power supply, and the clear pond of draining, will affect the process to sewage disposal.Cause the non-qualified discharge of sewage.And also be not easy to operation for the mud on the artificial flushing swash plate (inclined tube), and there is certain danger.
