Sugar refinery beet fluming wash water treatment facility
The utility model relate to sugar refinery produce in stream send the technical field of sewage of beet.
In the beet in sugar refinery was produced, stream sent the wash water of beet to recycle after the precipitation clarification.Mostly be to adopt peripheral charging not have raking device or floating sedimentation tank at present in settling tank, because the settling tank floor space is big, clarifying efficiency is low, contains in the overflow to float slag, and the backwater rate is low, and backwater is of poor quality, influences the normal operation of subsequent technique; The operational administrative complexity, the fluctuation of settling tank overflow quality index is big, and cycle water is poor.
The utility model provides a kind of sugar refinery beet fluming wash water treatment facility, and it can make settling area be several times as much as existing precipitation process equipment under identical floor space situation, has improved sewage treating efficiency effectively.
The utility model reaches by the following technical programs: the periphery along the pond body is disposed with feeding trough and water leg, in the feeding trough bottom, along circumference vertical supply pipe is set equidistantly, pond body upper parallel equidistant placement has the load-bearing I-beam of supporting tilted plate separator, the I-beam two ends are fixed on the body wall of pond, a support post is arranged in the middle of each I-beam, be arranged in parallel at the intravital tilted plate separator in pond apportion between adjacent I-beam, the tilted plate separator between each adjacent I-beam can be to be integral a plurality of being connected before and after each other.
Every capable tilted plate separator between adjacent I-beam is chained together each other by overflow groove from beginning to end, and the junction flexible elastomer is as India-rubber strip, sponge strip, foam plastics strip sealing.
Cross section is that step-like above-mentioned overflow groove has throttle orifice at bottom land, and the side wall upper part of groove is the water yield distribution plate that has breach; Throttle orifice pitch of holes and pore size equate.
The utility model compared with prior art has following advantage and positively effect: do not enlarging occupation area of equipment and increasing under the prerequisite that constructs the factory buildings, the sewage disposal device that design and installation the utility model provides in the settling tank of original peripheral feeding device, increase settling area and satisfy production requirement, dark awl bucket spoil disposal need not the raking device, but so tilted plate separator compact arrangement, with less floor space, reach higher throughput and backwater quality.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model; Fig. 2 tilted plate separator is arranged synoptic diagram at the pond inner plane; Fig. 3 is the vertical view of tilted plate separator; Fig. 4 is overflow groove transverse section and throttle orifice shape synoptic diagram.
As shown in the figure, be respectively equipped with feeding trough (2) and water leg (3) along pond body (1) inner peripheral wall, in feeding trough, along circumference by 20 vertical supply pipes (7) equidistantly are set, to realize uniform distribution; Adopt 11 I-beams (4) parallel equidistant to be arranged in the top in pond, tilted plate separator (5) hangs with I-beam and is connected, in order to improve supporting capacity, a support Steel Pipe Support (6) in the middle of the every I-beam; The I-beam two ends are placed on the outer wall on body top, pond by special seat ear (8), strain with stay-bolt; In the installation, earlier I-shaped beam seat ear is installed, again that I-beam is in place, look for benchmark with water level gauge, make each bar I-beam end be in same level, then I-beam and seat ear are welded together, and intermediate studdle is supportted; Between the intravital adjacent I-beam in pond tilted plate separator is housed, the tilted plate separator that is arranged between adjacent I-beam can be a plurality of, and front and back are concatenated into an integral body each other.
The tilted plate separator of in circular settling tank, arranging be the applicant at Chinese patent 94215907, disclosed content in by name " a kind of swash plate concentrating unit ".Install in the separator many parallel, spaced apart, and with the swash plate (9) of horizontal plane inclination certain angle; Sewage is introduced feeding trough by water inlet pipe, is evenly distributed to the bottom, pond along sub-feed tube, and the feed well on swash plate group avris bar enters between the swash plate, and the sedimentation treating processes is carried out between swash plate, and the primary water after the precipitation process overflows into water leg, flows out through rising pipe.Be furnished with not the tilted plate separator that string on the same group connects between every adjacent I-beam, each parameter of separator is determined according to physical size optimization; For increase tilted plate separator group number and inclined plate sedimentation area as far as possible, this device apportion in the circular area of pond body is arranged in parallel.
Each tilted plate separator device, top all have overflow groove (10), and overflow groove passes through the end place of plate group, constitute packaged type with sponge strip (11) sealing and connect; Allow certain displacement on the overflow groove length direction, the overflow groove of being convenient to each tilted plate separator combination in every row is end to end each other; Have throttle orifice (12) at the bottom of the overflow groove, the pressured difference of overflow is discharged through these holes, like this, shallow-layer all has nearest round between interior each plate of swash plate combination, avoided interfering with each other and causing turbulent flow, by the overflow of throttle orifice discharge, by having the water yield distribution plate (13) of semicircle breach, be collected to the intermediary water leg, flow to total overflow water leg; This design can guarantee the normal discharge of overflow under overflow groove is connected to each other the big situation of the long water resistance of stroke.
