Description
Technical field
The utility model relates to a kind of sewage disposal device, especially the anaerobism waste disposal plant.
Background technology
At present, in existing high suspended matter anaerobism sewage treatment process, injecting the sewage that to handle, generally adopting the mode of sprayed feed toward anaerobic jar.Owing to contain more solid substance and silt in the high suspended matter waste water, behind the entering anaerobic jar, poor because of the liquid fluidity in the jar, waste water and anaerobism liquid mixed effect are inhomogeneous.And it is more concentrated just to have got into jar interior high suspended matter waste water, the effect that can produce natural subsidence, and sediment settlement and accumulation can be formed gradually on the bottom; The final processing dead angle that forms in the anaerobic jar; Anerobes can not well contact with it and digest, and finally buries feed-pipe and forms the obstruction of feed-pipe charging jet hole, causes the anaerobic jar volume to reduce relatively; The efficient that directly causes anaerobic jar to handle waste water reduces, and reduces biogas output.Because the suitable fermentating liquid PH value of anerobes can not be lower than 6.5, the fermentation that is lower than 6.0 o'clock methanobacterias almost completely stops, and non-processor waste water can not produce biogas.And because the high suspended matter Waste Water Centralized that has just got at a few places, is brought the acidity-basicity ph value load impact to anaerobism to the processing of waste water, need add medicine carries out pH value and regulates, the pH value that guarantees to handle waste water about 7.0, thereby strengthened the cost of WWT.
Summary of the invention
The purpose of the utility model provides a kind of suspended substance anerobic sowage does not have the obstruction mixing device, should be able to overcome deficiency of the prior art, further improves fermentor tank efficient, increases biogas output.
In order to achieve the above object, the concrete technical scheme of the utility model is:
A kind of suspended substance anerobic sowage does not have the obstruction mixing device, and it comprises anaerobic jar, feed-pipe, blow-off pipe and escape pipe, it is characterized in that also comprising:
Be located at the bottom of said anaerobic jar and the annular gas distribution pipe above the feed-pipe;
The gas pipe that on said annular gas distribution pipe, evenly is provided with;
Inlet mouth is communicated with said anaerobic jar top escape pipe, the gas compressor that the air outlet is communicated with said annular gas distribution pipe.
Described gas pipe includes tracheae, valve pocket, non-return hole, non-return valve core, and production well and annular gas release groove constitute; Wherein, go into tracheae and communicate with valve pocket through non-return hole suitable for reading, non-return valve core places valve pocket, and valve cavity wall is provided with a plurality of production wells that communicate with exterior annular gas release groove, and the end opening of going into tracheae communicates with annular gas distribution pipe.
After anaerobic jar adopts said structure, in the bottom of anaerobic jar annular gas distribution pipe is set, according to the working radius of anaerobic jar floorage and single gas pipe; On gas distribution pipe, arrange perforate and the gas pipe that has non-return is installed; The pressurized back of biogas that produces from anaerobic jar gets into annular gas pipe, and the gas that utilizes gas pipe to discharge stirs, and plays moment blended effect; High suspended matter is put on liter by gas and is digested by anerobes; Silt is put on liter by gas, flows out anaerobic jar with the anaerobism water outlet, can not produce feed-pipe charging jet orifice phenomenon of blocking.
Figure of description
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the gas pipe 5 analysed and observe along the A-A line among Fig. 1;
In the drawings, anaerobic jar 1, biogas escape pipe 2, compressor 3, annular gas distribution pipe 4, gas pipe 5, blow-off pipe 6, feed-pipe 7, charging jet hole 8, non-return valve core 9, annular gas release groove structure 10, production well 11, tracheae 13 is gone in non-return hole 12, valve pocket 14 and liquid guide groove 15.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
Shown in Figure 1, be the structural representation of the utility model.From figure, can know, be provided with feed-pipe 7 and blow-off pipe 6 in the bottom of anaerobic jar 1, on feed-pipe 7, be provided with annular gas distribution pipe 4, on annular gas distribution pipe 4, evenly be provided with gas pipe 5.Bottom at anaerobic jar 1 is communicated with the air intake of compressor 3 through biogas escape pipe 2, and the air outlet of compressor 3 is communicated with annular gas distribution pipe 4 through pipeline.Wherein, the feed-pipe in the anaerobic jar 1 is provided with charging jet hole 8 at 7 the end, can high suspended matter waste water be injected in the anaerobic jar 1; Blow-off pipe 6 is used for the sewage in the drain tank; Compressor 3 is delivered to the annular gas distribution pipe 4 after pressurizeing the biogas that comes out from anaerobic jar 1.
Shown in Figure 2, be the structural representation of the gas pipe 5 analysed and observe along the A-A line among Fig. 1, from figure, can know that gas pipe includes tracheae 13, valve pocket 14, non-return hole 12, non-return valve core 9, production well 11 constitutes with annular gas release groove 10; Wherein, go into tracheae 13 and communicate with valve pocket 14 through non-return hole 12 suitable for reading, non-return valve core 9 places valve pocket 14, and valve cavity wall is provided with a plurality of production wells 11 that communicate with exterior annular gas release groove 10, and the end opening of going into tracheae 13 communicates with annular gas distribution pipe 4.Wherein, it is that the pressurized gas in the gas distribution pipe 4 can only be come out that gas pipe 5 is provided with the non-return purpose, and anaerobism liquid in the anaerobic jar 1 and suspended substance silt etc. can not get in the gas distribution pipe 4.
The principle of work of the utility model is:
High suspended matter waste water gets in the anaerobic jars 1 from feed-pipe 7, in charging jet hole 8, high suspended matter waste water is sprayed in the jar and produces biogas with anaerobism liquid hybrid reaction; The biogas that comes out from anaerobic jar 1 top escape pipe 2 is compressed the annular gas distribution pipe 4 of machine 3 pressurization back entering, and from gas pipe 5 ejections.The biogas of ejection impacts anaerobism liquid in the anaerobic jar and high suspended matter waste water; With anaerobism liquid and high suspended matter waste water good mixing effect; The firm high suspended matter waste water that gets in the jar is mixed with original anaerobism liquid in moment fully, make the waste water that newly advances with the anaerobism liquid moment mixing in the former jar, the impact that therefore can not produce local anaerobism liquid acidity-basicity ph value load in the jar; Need not add the medicine of regulating pH value, so just reduce the running cost of WWT.Take place in moment owing to mixing simultaneously; Therefore the anaerobism activity is comparatively violent, and violent anaerobism activity contacts with waste water and can produce a large amount of biogas, and the rising of biogas can produce the air supporting effect; Silt that gets into during with the anaerobic jar charging and suspended substance are along with together rising; Finally along with the water of discharging flows out anaerobic jar, at the bottom of can not being deposited on jar, cause the reduction of anaerobic jar load and the generation of acidifying phenomenon.Avoided suspended substance that charging jet hole 8 is stopped up simultaneously, and the many bad problem of bringing.
