Description
Technical Field
The utility model belongs to chemical industry environmental protection equipment field especially relates to a static mixing arrangement who adds the medicine in-process in biochemical degradation among waste water treatment.
Background
In the process of wastewater treatment, corresponding agents (such as hydrogen peroxide, organic acid, neutralizing alkali and the like) must be added in the process of entering wastewater into biochemical degradation, and the common method is to directly or spray the required agents into a biochemical degradation tank, so that the agents are often unevenly distributed, the biochemical treatment effect is reduced, and the service life of microorganisms is influenced.
Disclosure of Invention
The utility model aims at overcoming the not enough of prior art, providing a static mixing arrangement, can avoid directly or spray the entering biochemical degradation pond with the medicament and reduce the biochemical treatment effect because of the medicament distributes inhomogeneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a static mixing device, characterized by: a compressed air pipe and a medicament pipe are vertically inserted into the mixer, the bottom end of the compressed air pipe is vertically connected with an air drum pipe, the bottom end of the medicament pipe is vertically connected with a medicament injection pipe, and the compressed air pipe and the medicament pipe are both provided with control valves; the bottom of one side of the mixer is provided with a water inlet pipe, the upper part of the other side of the mixer is provided with a water outlet pipe, and the water inlet pipe and the water outlet pipe are both provided with control valves.
The air blowing pipe and the medicine injection pipe are arranged oppositely, the upper wall of the air blowing pipe is provided with a plurality of small holes, the lower wall of the medicine injection pipe is provided with a plurality of small holes, and air and medicine flowing out of the small holes on the air blowing pipe and the medicine injection pipe form reverse convection so that the medicine is fully mixed. The middle part is equipped with the sieve in the blender, evenly lays a plurality of round holes on the sieve, can further disperse the liquid of misce bene, and can eliminate the bubble in the blender, misce bene.
And the mixer is provided with a vent pipe.
The utility model has the advantages that: the bubbling mode is used for adding, the added medicament and the compressed air are in reverse contact below the liquid level of the wastewater, the mixing is sufficient, the medicament is uniformly mixed before the wastewater enters the biochemical degradation tank, and the problem of low utilization rate caused by uneven medicament addition is thoroughly solved.

Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
Example 1, see FIGS. 1-2: a static mixing device, characterized by: a compressed air pipe 2 and a medicament pipe 4 are vertically inserted into the mixer 1, the bottom end of the compressed air pipe 2 is vertically connected with an air blowing pipe 3, the bottom end of the medicament pipe 4 is vertically connected with a medicament injection pipe 5, and the compressed air pipe 2 and the medicament pipe 4 are both provided with control valves; the bottom of one side of the mixer 1 is provided with a water inlet pipe 8, the upper part of the other side is provided with a water outlet pipe 9, and the water inlet pipe 8 and the water outlet pipe 9 are both provided with control valves.
The air blowing pipe 3 and the medicine injection pipe 5 are arranged oppositely, the upper wall of the air blowing pipe 3 is provided with a plurality of small holes, the lower wall of the medicine injection pipe 5 is provided with a plurality of small holes, and the air and the medicine flowing out from the small holes on the air blowing pipe 3 and the medicine injection pipe 5 form reverse convection, so that the medicine is fully mixed.
The middle part is equipped with sieve 6 in the blender 1, evenly lays a plurality of round holes 7 on the sieve 6, can further disperse the liquid of misce bene, and can eliminate the bubble in the blender, misce bene.
The mixer is provided with a vent pipe 10 to prevent the pressure build-up of the compressed air blown into the mixer.
At first, open the control valve of inlet tube 8 and squeeze into blender 1 with waste water in, after having certain liquid level, open compressed air pipe 2's control valve and put into compressed air, then open the control valve of medicament pipe 4 and make the medicament enter into blender 1 in, because the gas and the medicine that the aperture on blast pipe 3 and the injection pipe 5 flowed out form reverse convection, make the medicament mix fully, in addition 6's of sieve effect, make the waste water homogeneous mixing after adding the medicine, then enter into next biochemical system through outlet pipe 9.
