Abstract
The utility model discloses a double-threaded jet aerator belonging to wastewater treatment equipment, and particularly relates to aeration equipment based on jet techniques. The double-threaded jet aerator is characterized in that the double-threaded jet aerator has a circular pipe-shaped housing with a water inlet at one end and an air/water outlet at the other end, the middle part of the housing is bended at 10-20 degrees, a conical jet ejector is arranged inside the water inlet, an air inlet pipe is arranged perpendicularly on the housing and positioned on one side of the jet ejector, the space between the nozzle of the jet ejector and the air/water outlet defines an air/water turbulent mixing chamber, a double-threaded guide groove is formed on the inner wall of the mixing chamber, and the water inlet and the air inlet pipe are both provided with connecting flanges. The utility model has the benefits as follows: the double-threaded guide groove is formed on the inner wall of the air/water turbulent mixing chamber of the aerator, so that water in the turbulent state and the air are completely mixed in the mixing chamber and the oxygen absorption rate is increased; and the reasonable layout of the nozzle of the jet ejector and the air nozzle can allow the formation of negative pressure in the air inlet pipe, so as to reduce the air pressure of the fan and save power sources. The double-threaded jet aerator has a simple structure, maintains unchanged performances after long-term operation, does not need repair and maintenance and has high reliability.
Description
Technical field
The utility model belongs to sewage treatment equipment, particularly adopts the aerator of fluidics.
Background technology
Aerating system is the core of aeration tank technology; The quality of aerating system performance is related to the success or failure of sewage treatment process, and the jet aerator technology is widely used in the processing of municipal effluent, trade effluent such as petroleum wastewater, wastewater from chemical industry, paper waste, dyeing waste water, food processing wastewater in recent years.Stopping up in use appears in conventional ejector easily, and waste gas, discharged waste water are big, and the rate of transform of oxygen is not high, has influenced its aeration effect.
The utility model content
The deficiency of be prone to stop up in order to overcome existing efflux aerator, aeration is inhomogeneous, energy consumption is high, the utility model provides a kind of pair of screw thread jet aerator, and this pair screw thread jet aerator has the advantage that aeration is even, volume is little, efficient is high.
The utility model solves the technical scheme that its technical problem adopted: a kind of pair of screw thread jet aerator; It is characterized in that: an end is the circle tube form shell body of air water outlet for the water-in the other end; There is the bending of 10-20 degree at the housing middle part; In the water-in is conical ejector, and inlet pipe is vertically mounted on the housing of ejector one side, is air water turbulent flow mixing section between the outlet of ejector nozzle to air water; The mixing section inwall is provided with two screw thread diversion trenchs, and water-in, inlet pipe all are equipped with the flange that connects usefulness.
Be provided with air nozzle in the described inlet pipe, the air outlet of said air nozzle is positioned at the rear portion of conical ejector jet hole.
The utility model is because the length that prolonged ejector, and air nozzle is arranged on the rear portion of ejector nozzle, because high speed jet fluidised form; Make the air nozzle air outlet be negative pressure state; Help air admission liquid gas is mixed fully, oxygen uptake rate is high, and dynamicefficiency is high.Higher 3～4 times than traditional aeration tank processing efficiency, aeration time can obviously shorten, and is applicable to various WWTs, comprises plug-flow aeration tank, mixed aeration pond, extended aeration pond, oxidation ditch, oxidation pond etc.This jet aerator is applicable to darker aeration tank, has reduced floor space, and system is simple, practices thrift investment cost.Air water turbulent flow mixing section inwall is provided with two screw thread diversion trenchs; Can make the current in the mixing section become turbulence state to make liquid gas thorough mixing; Improve the aeration effect, the rational deployment of ejector jet hole and air nozzle outlet makes and forms negative pressure in the inlet pipe, needs fan pressure low; The little treatment efficiency of power is high, practices thrift working cost.
The beneficial effect of the utility model is that this aerating apparatus air water turbulent flow mixing section inwall is provided with two screw thread diversion trenchs, can make the current in the mixing section become turbulence state liquid gas to mix fully, and oxygen uptake rate is high; The rational deployment of ejector jet hole and air nozzle outlet makes and forms negative pressure reduction fan pressure saving power source in the inlet pipe.Device structure is simple, and long-term operation performance is constant, maintenance free, and safety is high.
