Abstract
The utility model relates to a flow guiding type aerator which is composed of a motor, an impeller, a blower fan, an aeration head, and a flow guiding pipe, wherein, the flow guiding pipe is arranged in a sewage treating tank, the impeller is arranged in the flow guiding pipe and is connected with the motor through a drive shaft, and the aeration head is arranged above or below the impeller and is connected with the blower fan through an air supply pipe. The flow guiding type aerator can respectively control the impeller rotation and the air supply amount to realize the dual-purpose of stir and oxygenization. The oxygen transfer coefficient of the utility model can reach 50% and is much high than the oxygen transfer coefficients of other oxygenizing devices, and the power consumption is obviously lower than that of a conventional oxygenizing device. Due to the adoption of the low pressure blower fan, the work amount of running maintenance is small.
Description
The utility model relates to a kind of guide flow type aerator, belongs to technical field of sewage.
It is the main method of sewage disposal that aerobe is handled, and by the metabolic reaction of microorganism the organism in the sewage and other nutritive substance is removed.This process consumes oxygen, needs oxygenation continuously in water, and the quality of oxygen replenishing equipment and efficient are the greatest factor that influences aerobic treatment process and running cost.At present oxygen replenishing equipment can be divided into three major types: 1. blast aeration equipment: the pressurized air that is produced by gas blower is discharged by aeration head below the water surface, and bubble moves upward, gas-to-liquid contact, and oxygen transfer is in liquid in the bubble.2. mechanical aeration equipment: comprise that vertical pivot surface aerating machine and oxidation ditch change brush.Aerator rotates makes that the sewage surface is acutely more folded, sewage and air blending.In this course, airborne oxygen dissolves in the sewage, is a kind of surperficial gas replenishment process.3. other aerator: comprise jet-flow aeration equipment, aerator and impeller aerator under water under water, jet-flow aeration equipment are by water sprayer air to be sucked in the sewage, and the pressure water that enters water sprayer is provided by water pump, divide self-priming and two kinds of gas blower Gas feedings.Aerator is an a kind of small-sized aerator newly developed recent years under water, comprises motor, impeller and ventpipe, is immersed in the sewage, driven by motor impeller high speed rotating produces negative pressure at the impeller center, and air is inhaled into through ventpipe, and smashed by impeller, realize the oxygenation process.The impeller aerator still is blast aeration in essence under water, and impeller only plays and stirs and the bubble breaking effect under water.
The purpose of this utility model is a kind of guide flow type aerator of design, changes the structure of prior art, to realize oxygen-transfer efficiency height, the low purpose of power consumption.
The guide flow type aerator of the utility model design is made up of motor, impeller, blower fan, aeration head and thrust-augmenting nozzle.Thrust-augmenting nozzle places in the treatment tank, and impeller places thrust-augmenting nozzle, and impeller links to each other with motor by transmission shaft.Aeration head place impeller above or below, and link to each other with blower fan by blast tube.
In the guide flow type aerator, used aeration head is micropore aeration pipe or aeration plate, and the aperture of micropore is 0.001～0.5mm.
The guide flow type aerator of the utility model design has the following advantages: 1. can control impeller rotation and air demand respectively, realize stirring and the oxygenation dual purpose.2. the oxygen transfer ratio can reach 50%, is higher than other oxygen replenishing equipment far away, and power consumption is starkly lower than conventional oxygen replenishing equipment, only be equivalent to conventional oxygen replenishing equipment half or 2/3rds.3. owing to adopt fan with low voltage, the running maintenance workload seldom.4. have powerful oxygen supply and plug-flow agitaion, improved equipment work efficient greatly.5. can be applicable in the aeration tank of any load, also can replace oxidation ditch to change brush, under the situation of oxygen deprivation, the anaerobism that can be used for water stirs, and purposes is very extensive.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the used aeration head of the utility model.
Below in conjunction with accompanying drawing, introduce content of the present utility model in detail.Among Fig. 1 and Fig. 2, the 1st, motor, the 2nd, blower fan, the 3rd, transmission shaft, the 4th, impeller, the 5th, blast tube, the 6th, aeration head, the 7th, thrust-augmenting nozzle, the 8th, at the bottom of the pond, the 9th, micropore.
As shown in Figure 1, the guide flow type aerator of the utility model design is made up of motor 1, impeller 4, blower fan 2, aeration head 6 and thrust-augmenting nozzle 7.Thrust-augmenting nozzle 7 places in the treatment tank, and impeller 4 places thrust-augmenting nozzle 7, and impeller links to each other with motor 1 by transmission shaft 3.Aeration head 6 place impeller 4 above or below, and link to each other with blower fan 2 by blast tube 5.
Working process of the present utility model is: motor 1 promotes current and moves downward in thrust-augmenting nozzle 7 by 4 rotations of transmission shaft 3 impeller.Air is supplied with by blast tube 5 by blower fan 2, and emits from aeration head 6, and air filled cavity is moved downward at the bottom of the pond by current drive downwards then, overflows the water surface in the outside of thrust-augmenting nozzle 7 with upward water flow, and airborne oxygen dissolves in the water in large quantities in this process.Aeration head 6 can place the below of impeller 4, also can be above impeller, below the water surface.Aeration head adopts micropore aeration pipe or dish, and micro-pore diameter can be 0.001～0.5mm.
Claims (2)
1, a kind of guide flow type aerator is characterized in that this aerator is made up of motor, impeller, blower fan, aeration head and thrust-augmenting nozzle; Described thrust-augmenting nozzle places in the treatment tank, and impeller places thrust-augmenting nozzle, and impeller links to each other with motor by transmission shaft, aeration head place impeller above or below, and link to each other with blower fan by blast tube.
