Description

Jet stream melts device of air

Technical field

The utility model belongs to technical field of sewage, and specifically a kind of structure is simple, manufacturing cost is low, efficient Low consumption, jet stream with long service life melt device of air.

Background technique

Anoxic and aerobic biochemical process are together in series by AO technique, are a kind of follow-on sewage using activated sludge process Treatment process not only can also have certain dephosphorization and denitrification effect with degradation of organic substances.When processing, anoxic section is carried out in the pond A Processing, in the pond O carry out aerobic section processing.Traditional AO structure of reactor is extremely complex, generally comprises underwater in the pond A Blender, the underwater aerating system in the pond O, sludge reflux pump, the Aeration fan in computer room, multiple components such as centralized control cabinet, The equipment configured in system is very more, and electrical component is more, and system structure is complicated, and high failure rate, especially underwater component is more, It is very difficult to repair after failure and handle.

Also have in the prior art using water distributor and dissolved oxygen processing is carried out to the pond O, but it necessarily is greater than the pond O liquid level, makes Big with middle noise, dissolved oxygen effect is poor, needs water distributor number more.

In conclusion the AO process spent water of the prior art is handled so that energy consumption is high, the pond O is generally required with more aeration tubes, Once a certain or certain aeration tube damages, will result in for hypoxgia, sewage treatment is not up to standard, only stops production, and discharge water inspection dimension It repairs, is many times that can not repair, and machine room fan operation energy consumption is big, takes up a large area once there are problems.

Utility model content

The utility model aim is intended to provide that a kind of structure is simple, manufacturing cost is low, efficient low-consume, with long service life Jet stream melts device of air.

To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is that a kind of jet stream melts device of air, in which: packet Threeway mixing tube is included, the axial line of the first through hole of the threeway mixing tube and the second through-hole is located in a straight line, third through-hole Axial line and the axial line of the first through hole and the second through-hole be mutually perpendicular to；It is fixed with aqueduct at the first through hole, It is fixed with injection pipe in the second through hole, the third through-hole is located in air intake duct；The lower end of the aqueduct is from first through hole Place insertion threeway mixing tube inner cavity in, the internal diameter and outer diameter of the lower section of the aqueduct be respectively less than the upper section of aqueduct internal diameter and Outer diameter, so that being formed with mixing chamber between the outer wall of the lower section of aqueduct and the inner wall of threeway mixing tube, the aqueduct goes out The mouth of a river and the gas outlet of air intake duct are respectively positioned in mixing chamber, and the water outlet of aqueduct is located at below the gas outlet of air intake duct；Institute Stating has spacing between the inlet of injection pipe and the water outlet of aqueduct；The water inlet of the aqueduct is sewage inlet.

The utility model is compared with prior art advantageously: aeration efficiency is high, and low energy consumption, is suitable for a variety of dirts Water process operating condition.Reach filling for liquids and gases since jet stream melts device of air in the case where sewage is in the higher spray regime of speed Divide mixing, oxygen uptake rate is very high, and the dynamic efficiency of water pump is high.It facts have proved that the dissolved oxygen mode is carried out than traditional by blower The aeration tank treatment effeciency of aeration is 3~4 times high, and in the case where identical oxygen dissolving value, the aeration time of this kind of aeration mode can be bright It is aobvious to shorten.So that water distributor component is reduced, installation is extremely convenient, and the personnel of no any technology only need to spend 15 minutes can be complete Forming apparatus installation, and traditional equipment needs professional person to spend nearly 2 working days that could complete to install.Structure is simple, manufacture at This low, efficient low-consume, long service life.

Detailed description of the invention

The utility model can be further illustrated by the nonlimiting examples that attached drawing provides；

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

It is right with reference to the accompanying drawings and examples in order to make those skilled in the art that the utility model may be better understood Technical solutions of the utility model further illustrate.

Referring to attached drawing 1, the jet stream in figure melts device of air, in which: including threeway mixing tube 12, the of the threeway mixing tube 12 The axial line of one through-hole and the second through-hole is located in a straight line, and the axial line of third through-hole and the first through hole and second are led to The axial line in hole is mutually perpendicular to；It is fixed with aqueduct 13 at the first through hole, is fixed with injection pipe 14, institute in the second through hole Third through-hole is stated to be located in air intake duct 15；The inner cavity of threeway mixing tube 12 is inserted into the lower end of the aqueduct 13 from first through hole In, the internal diameter and outer diameter of the lower section of the aqueduct 13 are respectively less than the internal diameter and outer diameter of the upper section of aqueduct 13, so that aqueduct 13 The outer wall of lower section and the inner wall of threeway mixing tube 12 between be formed with mixing chamber 16, the water outlet and air-breathing of the aqueduct 13 The gas outlet of pipe 15 is respectively positioned in mixing chamber 16, and the water outlet of aqueduct 13 is located at below the gas outlet of air intake duct 15；It is described There is spacing between the inlet of injection pipe 14 and the water outlet of aqueduct 13；The water inlet of the aqueduct 13 is wastewater influent Mouth 11.In this embodiment, injection pipe 14 may be implemented to protrude into the liquid in the pond O, effectively realize aeration, easy to maintain, structure Simply, manufacturing cost is low, efficient low-consume, long service life.
