Description
Technical field
The utility model is related to a kind of increase flat flow air-float filtration after shallow air-floatation filtering, forms double air-float filtrations
Water treatment system, makes coagulant and flocculant have the longer time to carry out reagentia, and fiber removal is more thorough, road filtering after guarantee
It is more effective, more cleaning, special pair of air-float filtration water treatment system of wet method spun lacing of more high yield, belong to wet method spun lacing water treatment facilities
Field.
Background technology
At present, by the fiber that wet method spun lacing is used is superbhort fiber, the turnover rate of fiber is 5-8% after spun lacing, this
Few fibers just enter the water process circulatory system through vacuum suction, therefore the load and difficulty of wet method spun lacing water process are combed than conventional
Reason spun lacing is higher, and enterprise usually from the one kind in a kind of shallow air-floatation or flat flow air supporting, filters as first.But
During actual production, due to needing certain reagentia time after the coagulant such as addition PAC, the coagulation such as unreacted PAC in part
Agent easily enters into next road pipeline and Sand Filtration System with recirculated water, influences the cleaning of pipeline and the cleaning of sandfiltration pot, so that
The recoil frequency and filter efficiency of sandfiltration pot are influenceed, water quality is finally influenceed, is produced and easily block water needle plate, microorganism exceeded etc. to ask
Topic, in addition, single air supporting water treatment system to there is also aquifer yield low, it is impossible to meet high speed wet method spunlace non-woven production line water need
The problem wanted.
Utility model content
Purpose of design：The weak point in background technology is avoided, a kind of cleaning for both not interfered with pipeline and sand filtration is designed
The cleaning of tank, does not interfere with the recoil frequency and filter efficiency of sandfiltration pot again, and can ensure that water cleaning, will not block liquid drugs injection
Plate, the problems such as microorganism will not be produced exceeded, adapt to special pair of gas of wet method spun lacing of high speed wet method spun lacing production line water needs
Swim processing system.
Design：In order to realize above-mentioned purpose of design.The utility model is improved single air-flotation system, in shallow-layer
Increase flat flow air-float filtration after air-float filtration, form double air-float filtration water process, coagulant and flocculant is had longer
Time carrys out reagentia, and fiber removal is more thorough, and more effective more cleaning, the aquifer yield of road filtering are higher after guarantee.Shallow air-floatation
It is an advanced quick air-flotation system, on the basis of traditional air supporting theory, and has successfully used " shallow pool theory " and " zero
Speed " principle and integrating cohesion, air supporting, skimming, precipitating, scrape mud for designing, are a kind of high-efficiency appliances that purification of water quality is processed.
Two kinds of air-floating apparatus compare, and shallow air-floatation water velocity is fast, and action time is short；And flat flow air supporting water velocity is slow, effect
Time is long, and two sets of air-floating apparatus carry air dissolving system.Air dissolving system is using jet air-suction, when operating pressure is
During 0.4MPa or so, high-pressure water inlet is sprayed by the high speed in ejector, and air is sucked in very short time, and in mixing
During pipe high speed cuts into microbubble and dissolves in water to greatest extent, so that the dissolved air water of over-saturation is formed, by follow-up equipment
Decompression, discharge the dissolved air water containing a large amount of a diameter of 20~45um microbubbles, be combined with the flco in sewage, form steady
Fixed gas enclosure flco, floats up to the water surface together, completes the separation of wadding float.The suspension content of its spun lacing recycle-water（SS）For
100-150mg/l, shallow air-floatation crosses the suspension content of water after filter（SS）It is 5-15mg/l, water is outstanding after flat flow air-float filtration
Float content（SS）It is 0-2mg/l.
Technical scheme：Special pair of air supporting water treatment system of a kind of wet method spun lacing, by shallow air-floatation filter and flat flow
Gas-flotation filter device is constituted, and flat flow gas-flotation filter device is located at after shallow air-floatation filter, forms double air-float filtrations
Water treatment system.Two sets of air-floating apparatus carry air dissolving system.
The utility model compared with background technology, because the application increased flat flow after shallow air-floatation filter
Gas-flotation filter device, so as to form double air-float filtration water treatment systems, the system makes coagulant and flocculant have the longer time
Carry out reagentia, not only fiber removal is more thorough, after can ensureing road filtering it is more effective, more clean, and aquifer yield is higher,
High speed wet method spun lacing production line can be met uses water needs.
Brief description of the drawings
Fig. 1 is special pair of air supporting water treatment system schematic diagram of wet method spun lacing.
Specific embodiment
Embodiment 1：Referring to the drawings 1.Special pair of air supporting water treatment system of a kind of wet method spun lacing, by shallow air-floatation filter
Constituted with flat flow gas-flotation filter device and flat flow gas-flotation filter device is located at after shallow air-floatation filter, form double gas
Floating filtering water treatment system.Recycle-water enters water return tank, and water return tank delivery port is connected and super with super efficiency shallow air flotation device water inlet
Effect shallow air-floatation device is provided with matched air dissolving system, and super efficiency shallow air flotation device delivery port enters with horizontal flow air flotation device
The mouth of a river is connected and horizontal flow air flotation device is provided with matched air dissolving system, and horizontal flow air flotation device delivery port is intake to sand filtration
End, to bag type filter device water inlet end, bag type filter device water side is to clear water reserviors, clear water reserviors water side for sand filtering device water side
To double police's filter for installation water inlet ends, double police's filter for installation water sides are supplied water to spun-laced machine.
Shallow air-floatation crosses the suspension content of water after filter（SS）It is 5-15mg/l, the suspension of water after flat flow air-float filtration
