Abstract
The utility model relates to a methane collection device of an expanded granular sludge bed. The methane collection device comprises a cylindrical tank body and is characterized in that a three-phase separator arranged in an upper layer and a lower layer is arranged in the tank body, the three-phase separator comprises an upper group of triangular methane collecting hood and a lower group of triangular methane collecting hood, which are arranged in a staggered manner, the hypotenuse of the upper triangular methane collecting hood is partially overlapped with the hypotenuse of the adjacent lower triangular methane collecting hood, and the top parts of the triangular methane collecting hoods are connected with a methane main pipe through methane branch pipes. The methane collection device disclosed by the utility model is simple in structure and can collect methane generated by a reaction chamber below the three-phase separator.
Description
Technical field
The utility model relates to a kind of expanded granular sludge bed sludge gas collecting device, is applicable to sewage treatment area.
Background technology
Expanded granular sludge bed (EGSB; Expanded Granular Sludge Bed); It is third generation anaerobic reactor; Can be divided into into water water distribution system, reaction zone, three-phase separation area and water outlet canal system system, be used to the processing of multiple industrial organic waste water (like starch, beer, alcohol, butcher, monosodium glutamate, lemon etc.).Waste water is before the settling chamber that gets into EGSB, and bubble must obtain separating, and prevents that air chamber from producing a large amount of foams, and the collecting methane that simultaneously reaction chamber is produced gets up.
Summary of the invention
The purpose of the utility model is to provide a kind of expanded granular sludge bed sludge gas collecting device simple in structure.
To achieve these goals; The technical scheme of the utility model is: a kind of expanded granular sludge bed sludge gas collecting device; Comprise cylindrical tank body; It is characterized in that: be provided with upper and lower two-layer triphase separator in the said tank body; Said triphase separator is made up of the upper and lower two groups trilateral gas skirts that are crisscross arranged, and the hypotenuse of the hypotenuse of last trilateral gas skirt and adjacent following trilateral gas skirt is overlapped, and the top of said trilateral gas skirt is connected with the biogas house steward through the biogas arm.
Further, the two ends of said trilateral gas skirt are welded on the inwall of tank body.
The utlity model has following advantage: this expanded granular sludge bed sludge gas collecting device is simple in structure; The gas, liquid, solid mixed solution rises in the triphase separator; The biogas bubble is run into the inwall of trilateral gas skirt and is separated with solid, liquid effectively, and biogas collects through biogas arm and biogas house steward.
Description of drawings
Fig. 1 is the schematic top plan view of the utility model embodiment.
Fig. 2 is the cross-sectional schematic at A-A place among Fig. 1.
The 1-tank body, 2-trilateral gas skirt, 3-biogas arm, 4-biogas house steward, 5-water-sealed tank, 6-biogas torch.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration.
With reference to figure 1 ~ 2; A kind of expanded granular sludge bed sludge gas collecting device; Comprise cylindrical tank body 1, it is characterized in that: be provided with upper and lower two-layer triphase separator in the said tank body 1, said triphase separator is made up of the upper and lower two groups trilateral gas skirts 2 that are crisscross arranged; The hypotenuse of the hypotenuse of last trilateral gas skirt 2 and adjacent following trilateral gas skirt 2 is overlapped, and the top of said trilateral gas skirt 2 is connected with biogas house steward 4 through biogas arm 3.
In the present embodiment, two-layer triphase separator can get up the collecting methane in the waste water more up hill and dale; The two ends of said trilateral gas skirt 2 are welded on the inwall of tank body 1; Said biogas house steward's 4 end feeds the water-sealed tank 5 of tank body 1 top; Normal to guarantee tank body 1 internal pressure; When biogas is fewer, can be directly it be burnt, when biogas is many with biogas torch 6; Said water-sealed tank 5 also can be connected with the biogas gas-holder behind air water separator, and biogas is covered up.
This expanded granular sludge bed sludge gas collecting device is simple in structure; Organic waste water produces biogas in expanded granular sludge bed reaction chamber; The gas, liquid, solid mixed solution rises in the triphase separator; The biogas bubble is run into the inwall of trilateral gas skirt 2 and is separated with solid, liquid effectively, and biogas collects with biogas house steward 4 through biogas arm 3.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
Claims (2)
