Abstract
The utility model discloses a rotating reactor which is used for treating wastewater, and the wastewater entering into the reactor from the middle part is rotated at the upper part and is discharged out from the lower part. The rotating reactor comprises an inlet pipeline (1), a rotating tank body (2), an outlet pipe (3) and a valve (4), wherein, the inlet pipeline (1) is connected with the inner wall circumference projection of the columnar section of the rotating tank body (2) in a tangency way. The rotating reactor is characterized in that the inlet pipeline (1) is positioned at the 1/3-1/4 part under the liquid level of the columnar section of the rotating tank body (2); the included angle Theta between the axial line of the inlet pipeline (1) and the axial line of the rotating tank body (2) is 87-88 DEG; the outlet pipe (3) is positioned at the bottom part of the conical section of the rotating tank body (2); and the adjusting valve (4) is arranged on the outlet pipe (3). As the rotating reactor can enable the wastewater to be upwards rotated along the inner wall tangent of the columnar section of the rotating tank body, then downwards rotated under the gravity action, and finally discharged out from the outlet pipe at the lower part, the water flow cannot have short waterway phenomenon in the rotating tank body, not only flocculation acts fully and forms big floccus sedimentation easily, but also small floccus can only convolute at the upper part of the rotating tank body all the time, and the flocculation effect is ensured.
Description
Technical field
The utility model belongs to the wastewater treatment equipment technical field, is specifically related to a kind of being used for to screw off out the swirling flow reactor in the advancing of wastewater treatment flocculation reaction process.
Background technology
In most of sewage treatment process, all can be in sewage dosing coagulant, coagulant aids, so that the flocculation of the suspended substance in the water is agglomerating, be convenient to better remove.This reaction process generally is to carry out in coagulating groove, flocculation reaction groove respectively.In order to make this reaction more abundant, common coagulating groove and flocculation reaction groove all have corresponding whipping appts, so that suitable hydraulics to be provided to reaction, to make it generation and are easy to settled big flocculating body.Obviously, the whipping appts that is provided with not only will increase cost of investment, power consumption, also can increase equipment mounting hardness and maintenance cost, thereby, subsequent design occurs utilizes self power of pumping sewage, can produce the swirling flow stirring action, and the effect swirling flow reactor with extraordinary energy-saving effect usually is used to replace the flocculation reaction groove with whipping appts.But, existing swirling flow reactor, and since its structure formation or on advancing down, go out, perhaps enterprising down-output type, thereby have some shortcomings like this: (1) current residence time weak point, react not thorough; (2) the short flow phenomenon of current is arranged, make with the effusive flco of waste water to vary, wherein contained little settling of floccus performance is bad, causes follow-up sedimentation process deleterious.
Summary of the invention
The purpose of this utility model is the deficiency that exists at existing swirling flow reactor, and provides a kind of being used for to screw off out the swirling flow reactor in the advancing of wastewater treatment.
The utility model provides is used for screwing off out the swirling flow reactor in the advancing of wastewater treatment, this swirling flow reactor is to be made of influent stream pipeline, swirling flow casing, outflow tube and valve, influent stream pipeline and swirling flow casing cylindrical section tangent connection of inwall circumferential projection, it is characterized in that the influent stream pipeline is positioned at 1/3～1/4 place under the swirling flow casing cylindrical section liquid level, outflow tube (3) is positioned at the bottom of the conical section of swirling flow casing (2), and regulated valve (4) is provided with on it.
In order to make the power that revolves on the utility model reactor stronger, the utility model also is designed to 87～88 ° with the angle theta between influent stream conduit axis and the swirling flow casing axis.
Swirling flow reactor of the present utility model is before guaranteeing that the flocculation reaction effect is achieved in that processed waste water enters the swirling flow casing, in the influent stream pipeline, coagulating agent and coagulant aids have been added respectively earlier, and along with flow has been carried out pre-mixing, when the waste water that contains coagulating agent and coagulant aids enters the swirling flow casing, because the influent stream pipeline is positioned at 1/3～1/4 place under the swirling flow casing cylindrical section liquid level, and it is tangent with the cylindrical section inwall circumferential projection of swirling flow casing, and become 87～88 ° angle again with the angle theta of swirling flow casing axis, thereby can make waste water along revolving on the inwall tangent line of swirling flow casing cylindrical section, become backspin in action of gravity again then, the outflow tube by the bottom flows out at last.In this process, the waste water on import top is by swirling flow, and suspended substance wherein collides mutually, and under coagulating agent and coagulant aids effect, grows up into flco rapidly, reach certain volume after, swirling flow downwards continues to grow up.The flco of not growing up can stay in the swirling flow of the top of import, can not arrive the outflow tube of bottom.Because the time of growing up of flco has comprised the time of the swirling flow that makes progress and the time of swirling flow downwards, thereby with conventional swirler relatively, the time of hybrid reaction is elongated, easier formation big flocculating body, have only big flocculating body just to enter the backspin part in addition, thereby guaranteed flocculating effect.
Compared with the prior art the utility model also has the following advantages:
1, can become backspin in action of gravity again along supination on the inwall tangent line of swirling flow casing cylindrical section owing to enter the utility model current, thereby short flow phenomenon can not appear in current in the swirling flow casing, make suspended substance in the water that the long swirling flow reaction times be arranged, for the increase of flco provides temporal assurance.
2, because the axis of the utility model influent stream pipeline and the angle theta of swirling flow casing axis are 87～88 °, thereby can allow current produce to revolve, this has not only prolonged the swirling flow reaction times, also make little flco be retained in the top of swirling flow casing all the time, after growing up, just can enter into the swirling flow lower box, avoid the problem of prior art existence, further guarantee the effect of flocculation reaction.
