A device for improving the air-float segregation effect comprises a dissolved air releasing-mixing pool, a guide plate, and an air-float solid-liquid separating pool, and a residue scraping machine is provided above the gas-floating solid-liquid separate pool. The utility model is characterized in that: the device for improving the air-float segregation effect also comprises a current plate arranged in the solid-liquid separate pool, and the fixing device of the positioning strip arranged on the pool wall of the solid-liquid separate pool; and the positioning strip restricts the position and the direction of the current plate. The utility model improves the hydraulic condition of the separating pool, and decreases the reynolds number of the water current in the separating pool. Thus, the separating region which is commonly in the turbulent condition at present is in or is close to the laminar condition, the interference to the fiberized granules in the floating process is reduces, and the floating rate is raised. The design current velocity adopted at present can be raided to about 15m/h form the 6 to 8m/h. The air-float separating effect is raised under the situation of the same processing capacity, and the water quality of the yielding water is better.
Description
Technical field:
The utility model relates generally to the structure of water treatment facilities air-floating apparatus, relates in particular to the improvement of water treatment flotation tank inner structure.
Background technology:
In the research to dissolved air flotation mechanism, all only being subjected to gravity, buoyancy and resistance with flocs with gas is prerequisite and foundation, uses Newton's second law then and obtains its ascent rate at present.Yet in actual conditions, band wadding particle also is subjected to the influence of streamflow regime except that being subjected to above-mentioned various power, and stressing conditions differs greatly in turbulent flow and laminar condition.Add in the water wadding grain and vary in size, different, surface nature is also different, and in floating-upward process its size also in continuous variation.Therefore wadding grain come-up can not uniform motion.
Because the design of air supporting at present generally all is under the wadding stream condition, above-mentioned factor is very obvious to the influence of flocs with gas ascent rate, and theory analysis and actual conditions differ bigger.In the design of present air-floating apparatus, the engineering staff generally can only adopt well below the ascent rate of theory or strengthen the Disengagement zone size and design.So solid-liquid separation effect all differs far away with theoretical value in actual engineering, solid-liquid separation effect is poor.For head it off, the patent No. is 01222525.8, and name is called " solid-liquid separation tank retaining device " and discloses a kind of structure, has increased baffle plate in solid-liquid separation tank, to improve the influence of turbulent flow to come-up wadding particle, solid-liquid is effectively separated.But,, thereby this problem is effectively solved simultaneously because direction that baffle plate is provided with and angle are bigger to the turbulent flow influence because this patent document does not disclose the concrete structure of baffle plate.
Summary of the invention:
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of device that improves the dissolved air flotation effect is provided.
The purpose of this utility model can be by realizing by the following technical solutions: a kind of device that improves the dissolved air flotation effect, include molten gas and discharge mixing pit (9), deflector (10), air supporting solid-liquid separation tank (11), and being provided with Slag Scraping Device (8) above it, its main feature is also to include to be provided with cowling panel (1) in solid-liquid separation tank (11); Cowling panel (1) is provided with positioning strip (3); The pool wall of solid-liquid separation tank (11) is provided with the fixture (4) of positioning strip (3), the position and the direction of positioning strip (3) restriction cowling panel (1).In separate tank, set up cowling panel, can effectively increase wetted perimeter, thereby reduce Reynolds number R greatly
c, reduce the interference of turbulent flow to band gas particle come-up, help improving ascent rate.It reduces degree and can utilize the cowling panel computational methods to determine according to designing requirement.Cowling panel quantity is many more, and it is big more to reduce degree.
The device of described raising dissolved air flotation effect also includes and is provided with a cowling panel (1) at least; Be arranged in parallel between cowling panel (1) plate and the plate.Its quantity and distance between plates are from being determined by the cowling panel computing formula.Quantity is many more, and spacing is more little, and effect is good more.Arrange by water (flow) direction.
The positioning strip (3) of the device of described raising dissolved air flotation effect is provided with locating slot (31), and the width of its locating slot is greater than the thickness of cowling panel (1).
The thickness of cowling panel of the present utility model (1) is 1-4mm.Distance between plate and the plate is 15-150mm.
The angle of the plate face of described cowling panel (1) plate face and deflector (10) is the 0-90 degree.Angle at the bottom of cowling panel (1) plate face and solid-liquid separation tank (11) pond is the 25-90 degree.The upper top of cowling panel (1) is lower than the scraper plate 50-150mm of Slag Scraping Device (8); The lower bottom part of cowling panel (1) is higher than solid-liquid separation tank (11) bottom surface, pond 100-250mm.
The length of cowling panel (1) is the length less than solid-liquid separation tank (11), greater than 1/2 length of solid-liquid separation tank (11).
The fixture (4) that improves the device of dissolved air flotation effect also includes bolt (41), spring washer (42), backing plate (43).
The beneficial effects of the utility model are to improve the hydraulics of separate tank, the Reynolds number of current in the reduction separate tank, make the Disengagement zone that generally is in turbulent condition at present, be in or near laminar condition, reduce, improve ascent rate the interference in the flocs with gas floating-upward process.The design current velocity that adopts at present by 6-8m/h, can be brought up to about 15m/h.Under same treatment amount situation, improve the dissolved air flotation effect, make effluent quality better.
