Description
Technical field
The utility model relates to the vitals in the air-flotation system, specifically a kind of air buoyancy tank.
Background technology
In sewage flotation treatment process, the dissolved air water that is produced by molten mechanism of qi is discharged in the processed waters by reliever, saturated dissolved gas water discharges micro-bubble and upwards floats under normal pressure, in the bubble floating process with the floating water surface of going up of the suspended solid in the sewage (SS), utilize instrument such as scraper plate that suspended substance is removed then, realize solid-liquid separation.Above-mentioned a series of process all is to finish in a casing that is called air buoyancy tank.The casing of the air buoyancy tank that generally uses is horizontal rectangle structure at present, whole air buoyancy tank by exposure chamber (molten air chamber), separate chamber, adopt grit chamber, dreg collecting slot, overflow port etc. and form, exposure chamber, separate chamber, to adopt the grit chamber relatively independent, and the volume size of each part all has certain proportion.Arrive the exposure chamber behind the sewage flocculation, in the exposure chamber, contact with the microbubble that from reliever, comes out, bonding, and flow to the separate chamber together, in separate chamber's process of flowing, suspended solid in the sewage upwards floats under the microbubble buoyancy function together, enter and scraped into dreg collecting slot by slag scraper after adopting the grit chamber, treated water then overflows from overflow port, thereby realizes solid-liquid separation.The shortcoming of this air buoyancy tank is that cabinet space utilizes rate variance, because the maximum separate chamber's effective volume that takes up space has only its upper part, causes that this occupation area of equipment is big, manufacturing cost is high, and transportation is inconvenient; On the other hand, in the exposure chamber, the come-up direction of the flow direction of sewage and bubble at an angle of 90, the sewage that is in the upper strata is easy to miss the chance that contacts with microbubble, and suspended solid wherein can not be held up, thereby influenced the utilization ratio of microbubble, also just influenced the processing efficiency of system.
The utility model content
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, and a kind of vertical-type air-flotation case is provided, and to improve wastewater treatment efficiency and plant factor, reduces floor space, convenient transportation.
For this reason, the technical solution of the utility model is: the vertical-type air-flotation case, comprise vertical cabinet, and it is characterized in that the top of casing is equipped with the sewage water inlet pipe road, its water outlet is positioned at casing; The bottom of casing is equipped with the dissolved air water suction culvert, and its water outlet is positioned at casing, and water-in is positioned at outside the casing; Casing is provided with outlet pipeline outward, and its water-in is opened on the casing that is positioned at below the dissolved air water suction culvert.The utility model will have now air buoyancy tank each functional component such as exposure chamber, separate chamber, adopt grit chamber etc. and merge into one, form a vertical tubular casing, processed sewage is guided to the top of casing, and the outlet of dissolved air water is placed on the bottom of casing, and promptly dissolved air water discharges from the bottom of air supporting casing.The velocity contrast that the utility model utilizes the lift of molten gas bubble floating and sewage to descend increases the duration of contact of bubble and sewage, helps the adhesion come-up of bubble to SS, and is timing at velocity contrast, causes the rising stalling characteristic, reaches the air supporting purpose.Because in the contact process of the dissolved air water of suspended solid that descends and rising, both direction of motion is relative, be that sewage is to move from top to bottom, and dissolved air water is to move from bottom to top, both touch opportunities are very abundant, and microbubble meeting in the process of come-up is bonding and float a considerable amount of suspended substances, so the utilization ratio of bubble is very high, the processing efficiency that is to say system device is higher, has improved sewage treatment effect.Owing to having cancelled existing exposure chamber, separate chamber, having adopted the casing that the grit chamber merges becomes a tubular, the space availability ratio of equipment is improved, and has reduced manufacturing expense and trucking costs in addition.Casing can vertically be placed simultaneously, has reduced the floor space when equipment is installed.
Described vertical-type air-flotation case, the water outlet of dissolved air water suction culvert is provided with reliever, is used for the dissolved air water ideal is discharged.
Described vertical-type air-flotation case is provided with the water outlet current collector that is positioned at dissolved air water suction culvert below in the casing of bottom, its water-in with outlet pipeline is relative.The liquid that collecting ring comes out is discharged into the water inlet of outlet pipeline by water level overflow control sluice.
Described vertical-type air-flotation case, the top of casing is provided with a slag scraper, and the scum silica frost that slag scraper will float is scraped in the dreg collecting slot.
Described vertical-type air-flotation case, the bottom of casing is provided with a delivery pipe, is used to discharge the intravital partly precipitated thing of case.
The utility model will have now air buoyancy tank exposure chamber, separate chamber, adopt grit chamber etc. and merge into a vertical cabinet, simple and reasonable for structure, have following beneficial effect: improved the space availability ratio of equipment, reduced manufacturing expense and trucking costs, convenient transportation; The vertical placement of casing has reduced the floor space when equipment is installed; In the contact process of suspended solid and dissolved air water, both direction of motion is relative, has improved wastewater treatment efficiency and plant factor.
Below in conjunction with Figure of description the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
