The present invention provides a kind of efflux aerator, including water inlet pipe (1), mixing chamber (2), the right-hand member of described water inlet pipe (1) stretches in mixing chamber (2), the top of mixing chamber (2) is provided with air inlet pipe (3), the right-hand member of mixing chamber (2) is connected with discharge pipe line (12) by venturi pipeline, described Venturi tube includes contraction flow region (4), throat (5), diffusion part (6), described air inlet pipe (3) is divided into left air inlet pipe (7) and right air inlet pipe (8) by dividing plate (13), described right air inlet pipe (8) stretches into throat (5) right-hand member by aspirating pipeline (14), described aspirating pipeline (14) is arranged along venturi pipeline upper inside wall.This device aeration effect is good, can be easy to external high-pressure air source.
Description
Technical field
The present invention relates to technical field of sewage is and in particular to a kind of efflux aerator.
Background technology
In wastewater treatment process, generally require to increase the contact area of water and air by aeration, traditional aerator structure is simple, and aeration effect is undesirable, and inconvenient plus high-pressure source of the gas.
Content of the invention
The problem existing for above-mentioned prior art, the present invention provides a kind of efflux aerator, and this device aeration effect is good, can be easy to external high-pressure air source.
To achieve these goals, the present invention provides a kind of efflux aerator, including water inlet pipe, mixing chamber, the right-hand member of described water inlet pipe stretches in mixing chamber, the top of mixing chamber is provided with air inlet pipe, the right-hand member of mixing chamber is connected with discharge pipe line by venturi pipeline, described Venturi tube includes contraction flow region, throat, diffusion part, described air inlet pipe is divided into left air inlet pipe and right air inlet pipe by dividing plate, described right air inlet pipe stretches into throat's right-hand member by aspirating pipeline, and described aspirating pipeline is arranged along venturi pipeline upper inside wall.
In this technical scheme, it is divided into left air inlet pipe and right air inlet pipe by making air inlet pipe, and makes right air inlet pipe stretch into the right-hand member of throat by aspirating pipeline, so, when using the apparatus, left air inlet pipe is directly connected with mixing chamber, source of the gas can be provided for first order aeration；Setting by right air inlet pipe and aspirating pipeline, so through throat mixing wastewater with air liquid due to meeting diffusion part produce high-speed eddy, and then aspirating pipeline suction part air can also be passed through, can further improve aeration effect, outer high-pressure air source can also be utilized in use as needed to provide pressure-air by right air inlet pipe and aspirating pipeline for throat's right-hand member, to improve aeration effect.
Further, the stage casing top of described discharge pipe line is provided with hemispheric teat, and the top of described teat is provided with time air inlet pipe.Mixing wastewater with air liquid can form high-speed eddy in teat, can not only improve the effect of mixing wastewater with air further, and can be by time air inlet pipe suction part air again, thus can further improve gas explosion effect.
The stage casing of described diffusion part is provided with filter screen, and the grid mesh number of described filter screen is 15-30 mesh.The setting of filter screen, can make the minute bubbles in mixing wastewater with air liquid be further divided into minute bubbles, expand the contact area of water and wholesale price, thus can improve gas explosion effect further.
Brief description
Fig. 1 is the structural representation of the present invention.
In figure：1st, water inlet pipe, 2, mixing chamber, 3, air inlet pipe, 4, contraction flow region, 5, throat, 6, diffusion part, 7, left air inlet pipe, 8, right air inlet pipe, 9, teat, 10, secondary air inlet pipe, 11, filter screen, 12, discharge pipe line, 13, dividing plate, 14, aspirating pipeline.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of efflux aerator, including water inlet pipe 1, mixing chamber 2, the right-hand member of described water inlet pipe 1 stretches in mixing chamber 2, the top of mixing chamber 2 is provided with air inlet pipe 3, the right-hand member of mixing chamber 2 is connected with discharge pipe line 12 by venturi pipeline, described Venturi tube includes contraction flow region 4, throat 5, diffusion part 6, described air inlet pipe 3 is divided into left air inlet pipe 7 and right air inlet pipe 8 by dividing plate 13, described right air inlet pipe 8 stretches into throat 5 right-hand member by aspirating pipeline 14, and described aspirating pipeline 14 is arranged along venturi pipeline upper inside wall.It is divided into left air inlet pipe 7 and right air inlet pipe 8 by making air inlet pipe 3, and makes right air inlet pipe 8 stretch into the right-hand member of throat 5 by aspirating pipeline 14, so, when using the apparatus, left air inlet pipe 7 is directly connected with mixing chamber 2, source of the gas can be provided for first order aeration；Setting by right air inlet pipe 8 and aspirating pipeline 14, so through throat 5 mixing wastewater with air liquid due to meeting diffusion part 6 produce high-speed eddy, and then aspirating pipeline 14 suction part air can also be passed through, can further improve aeration effect, this completes second aeration, outer high-pressure air source can also be utilized in use as needed to provide pressure-air by right air inlet pipe 8 and aspirating pipeline 14 for the gas-vapor mix liquid of throat 5 right-hand member, to improve aeration effect.
The stage casing top of described discharge pipe line 12 is provided with hemispheric teat 9, and the top of described teat 9 is provided with time air inlet pipe 14.Mixing wastewater with air liquid can form high-speed eddy in teat 9, can not only improve the effect of mixing wastewater with air further, and can be by time air inlet pipe 10 suction part air again, thus can further improve gas explosion effect.
The stage casing of described diffusion part 6 is provided with filter screen 11, and the grid mesh number of described filter screen 11 is 15-30 mesh.The setting of filter screen 11, can make the minute bubbles in mixing wastewater with air liquid be further divided into minute bubbles, expand the contact area of water and wholesale price, thus can improve gas explosion effect further.
