Abstract
The utility model discloses a dissolved air vessel in an air flotation tank, comprising a vessel body used for dissolving air; each end of the vessel body is provided with an end cover, a water inlet and a water outlet; the vessel body is formed by butting and communicating two sections of equal-sized cylinders; each section of cylinder wall is provided with an air inlet; an air distributing plate is arranged at the air inlet side in the cylinder; and the two air inlets are arranged in parallel in opposite directions. In the utility model, the two air inlets arranged in parallel in opposite directions are arranged on the wall of the vessel body and the air distributing plates are arranged at the corresponding positions in the vessel body, therefore, the air bubble quantity in the dissolved air vessel can be improved greatly; furthermore, the air bubbles can be distributed uniformly and have moderate sizes so that fine fibers in the air flotation tank can quickly float on water surfaces so as to be removed; and the deslagged water is clear and contains little fine fibers, and the water purifying effect is greatly improved.
Description
Technical field
The utility model relates to a kind of papermaking wastewater treatment facility, particularly relates to a kind of air flotation pool dissolving.
Background technology
Often use flotation waste water treatment equipment to carry out sewage disposal in field of papermaking, so that its recycle, the water resources of saves valuable.The air flotation pool dissolving is a major parts in the flotation waste water treatment equipment, and its effect is to generate a large amount of dissolved air waters so that a large amount of fiber fines in the processed water are bubbled through the water column.According to its use properties characteristics, it is particularly crucial that bubbles volume that is generated in the dissolving and distribution thereof and bubble size seem, but traditional dissolving inlet mouth is single, be difficult to adjust suitable molten gas air pressure and air input and satisfy big water treatment requirement of loading, the dissolving charge flow rate is found to be attached together with fiber fines if charge flow rate meeting bigger than normal causes molten carbonated drink to discharge bigger than normal being difficult to of back bubble by adjusting, bigger bubble also very easily breaks simultaneously, do not reach pneumatically supported effect, so its slagging-off is limited in one's ability, the slagging-off effect also has much room for improvement.
The utility model content
Technical problem to be solved in the utility model provide a kind of bubbles volume big, be evenly distributed, air flotation pool dissolving that the air supporting slagging-off is effective.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of air flotation pool dissolving, comprise the tank body that is used for molten gas, the two ends of tank body are provided with end cap, water-in and water outlet, its tank body is docked and connected by great circle column-shaped barrels such as two sections and forms, be respectively arranged with inlet mouth on every section barrel wall, air inlet side is provided with air distribution plate in the cylindrical shell, and two inlet mouths are parallel reversed arrangement.
A kind of air flotation pool dissolving of the utility model, by being the inlet mouth of parallel reversed arrangement and after the corresponding position is provided with air distribution plate in tank body being provided with two on the tank wall, can improve the bubbles volume in the dissolving greatly, and very even, the big or small appropriateness of bubble distributes, make the fiber fines in the air flotation pool can float fast to the water surface like this so that remove, water outlet after the slagging-off is limpid and to contain fiber fines few, has improved purifying water effect greatly.The usage quantity of simultaneously also less water purification agent polymerize aluminum chloride and polyacrylamide has increased the processing power of air-floatation water purifier.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural front view of a kind of air flotation pool dissolving of the utility model.
Fig. 2 is the local structure vertical view of a kind of air flotation pool dissolving of the utility model.
Wherein, Reference numeral: 1 is tank body, and 2 is end cap, and 3 is water-in, and 4 is water outlet, and 5 is inlet mouth, and 6 is air distribution plate, and 7 for weighing apparatus pushes back pipe, and 8 is sewage draining exit.
Embodiment
Disclosed all features in this specification sheets, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification sheets (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
As depicted in figs. 1 and 2, a kind of air flotation pool dissolving of the utility model comprises the tank body 1 that is used for molten gas, the two ends of tank body 1 are provided with end cap 2, water-in 3 and water outlet 4, between water-in 3 and tank body 1, also be connected with weighing apparatus and push back pipe 7, on the end cap 2 of water outlet 4 sides, also offer sewage draining exit 8, its tank body 1 is docked and connected by great circle column-shaped barrels such as two sections and forms, be respectively arranged with inlet mouth 5 on every section barrel wall, inlet mouth 5 sides are provided with air distribution plate 6 in the cylindrical shell, two inlet mouths 5 are parallel reversed arrangement, and the vertical range between two inlet mouths 5 is greater than at about 1/3rd of tank body 1 total length.During use, the intake pressure of two inlet mouths 5 is set to 0.74mpa, and flow set is that 1.2m/h is comparatively suitable.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
