Abstract
The utility model discloses a dissolved air floatation contact chamber which is arranged in a dissolved air floatation box, and is characterized in that a baffle is arranged in the contact chamber; a cylinder arranged horizontally is arranged at the bottom of the contact chamber; and one part of the cylinder is located in the air floatation box, and the other part of the cylinder is located outside the air floatation box. The dissolved air floatation contact chamber is simple and exquisite in structure, the mixing efficiency of sewage and dissolved air water is greatly improved, and the treatment efficiency of a dissolved air floatation system is improved.
Description
Technical field
The utility model belongs to the environmental protection equipment technical field, relates to pressure air-dissolving air-float system, relates in particular to a kind of air-dissolving air-float exposure chamber.
Background technology
Air-dissolving air-float system is a kind for the treatment of process in sewage flotation treatment process, it is after the dissolved air water that produced by " molten mechanism of qi " is injected in processed sewage after reliever discharges, saturated dissolved gas water discharges micro-bubble and upwards floats under normal pressure, take the suspended substance in sewage to the water surface in the bubble floating process, then utilize the instruments such as scraper plate that suspended substance etc. is removed.
Seen air-dissolving air-float system in the market, its exposure chamber is a rectangular parallelepiped cavity, in actual use, and when effluent stream during through this cavity, the microbubble discharged from reliever contacts with the suspended solid sewage, and clings suspended substance and upwards float together.The shortcoming of this exposure chamber is that the space of sewage and microbubble contact position is relatively large, the probability less that microbubble contacts with suspended substance in sewage, only have the part micro-bubble can cling and float suspended substance, some microbubbles directly float because touching less than suspended substance, affected the utilization ratio of microbubble, also just affected the processing efficiency of equipment, had much room for improvement.
As from the foregoing, address these problems very necessary!
In view of this, the inventor has done deep research to this, designs a kind of new air-dissolving air-float exposure chamber, its exquisiteness simple in structure, greatly improved the mixing efficiency of sewage and dissolved air water, also just improved the processing efficiency of air-dissolving air-float system, this case produces thus.
The utility model content
The purpose of this utility model is for a kind of air-dissolving air-float exposure chamber is provided, and exquisiteness simple in structure improves the mixing efficiency of sewage and dissolved air water greatly, improves the processing efficiency of air-dissolving air-float system.
For achieving the above object, the technical solution of the utility model is:
A kind of air-dissolving air-float exposure chamber, be arranged in the air supporting casing, it is characterized in that: be provided with baffle plate in exposure chamber, be provided with the cylinder of arranged transversely in bottom, the part of cylinder is at the air supporting box house, and another part is in the air buoyancy tank external body.
Further, described cylinder is in the part of air supporting casing the inside, and its upper end is provided with a level fluting, and in the part of external of air buoyancy tank, its end connects sewage water inlet pipe and dissolved air water water inlet pipe.
Further, the import of described sewage water inlet pipe is connected with cylinder is tangent.
Further, the import of described dissolved air water water inlet pipe is connected with cylinder is tangent.
Further, described sewage and the dissolved air water that enters exposure chamber rotatablely moves along cylinder axis, and sense of rotation is consistent.
The utility model is in actual moving process, due to sewage water inlet pipe, dissolved air water water inlet pipe and cylinder is tangent is connected, like this when sewage and dissolved air water enter, can flow into along the cylinder axis direction rotation, and sense of rotation is consistent, both can not collide, and mutual promotion, stirring action are arranged on the contrary, facilitate entering of sewage and dissolved air water, the more important thing is that both can be good at mixing.
And the setting of cylinder is limited the path of sewage and dissolved air water, is also the mixing efficiency that has improved both, and makes mixed sewage and dissolved air water flow into equably the horizontal direction at casing by the elongated slot on top.Compared with prior art, the time lengthening that both are mixed, distance is also elongated, mixing efficiency improves greatly, after mixing from groove evenly out.
The effect of its baffle plate is to force mixed sewage to be flowed directly to liquid level, reduces the time that suspended substance floats.
The beneficial effects of the utility model: the utility model exquisiteness simple in structure, greatly improve the mixing efficiency of sewage and dissolved air water, improve the processing efficiency of air-dissolving air-float system.
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model master apparent direction.
Fig. 2 is the structural representation that the utility model is overlooked direction.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to accompanying drawing 1 and accompanying drawing 2, the present embodiment discloses a kind of air-dissolving air-float exposure chamber, be arranged in the air supporting casing, a part that belongs to the air supporting casing, it is characterized in that: be provided with baffle plate 2 in exposure chamber 1, be provided with the cylinder 3 of arranged transversely in bottom, the part of cylinder 3 is at the air supporting box house, and another part is in the air buoyancy tank external body.
Further arrange, described cylinder 3 is in the part of air supporting casing the inside, and its upper end is provided with a level fluting 4, and in the part of external of air buoyancy tank, its end connects sewage water inlet pipe 5 and dissolved air water water inlet pipe 6.
Further arrange, the import of described sewage water inlet pipe 5 is connected with cylinder 3 is tangent.
Further arrange, the import of described dissolved air water water inlet pipe 6 is connected with cylinder 3 is tangent.
Further arrange, the described sewage that enters exposure chamber and dissolved air water are along cylinder 3 axis rotations, and sense of rotation is consistent.
The foregoing is only an embodiment of the present utility model, not to the restriction of this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
