Catering trade will produce a large amount of changing food wastes every day, except a part is for feed, other very major part be dropped processing.In addition,, on market, fruits and vegetables has also produced a large amount of fruits and vegetables rubbish in the process of packing, transportation and sale, has not only caused waste, simultaneously also to environment.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of changing food waste to produce the desulfurizer of biogas, has feature simple in structure, operation cost is low and safe.
To achieve these goals, the technical solution adopted in the utility model is: a kind of changing food waste is produced the desulfurizer of biogas, include treating pond, in treating pond, being provided with security device is connected, the entrance of security device is connected with dry-type methane storage tank with no pressure, make-up pipe provides supplementary feed to security device, security device firedamp drainage mouth is connected with biological desulphurization tower by pipeline, on the pipeline between security device and biological desulphurization tower, be connected with air supply pump, recycle pump has been delivered to the circulation of biological desulphurization tower top by the circulation fluid in biological desulphurization tower and has been sprayed, the biogas delivery port of biological desulphurization tower is connected with the inlet mouth of dry-type desulfurizing tower by pipeline, the venting port of dry-type desulfurizing tower is connected with using appts.
Described biological desulphurization tower bottom is connected with nutrition agent pipeline.
The inner sweetening agent of filling iron oxides of described dry-type desulfurizing tower.
In described thing thionizer, be filled with the carrier-filler that maintains microorganism existence.
The beneficial effects of the utility model are:
The utility model, owing to having adopted biological desulphurization tower, can carry out desulfurization processing by the hydrogen sulfide in biogas, and after desulfurization is processed, the concentration of hydrogen sulfide in methane is 100ppm;
Due to air supply pump, for the breathing of microorganism provides sufficient oxygen;
The inner sweetening agent of filling iron oxides of dry-type desulfurizing tower, can effectively remove the hydrogen sulfide in biogas, and the concentration of hydrogen sulfide in methane is 1ppm;
Due to the device that has adopted biological desulphurization tower to combine with dry-type desulfurizing tower, greatly reduced the usage quantity of sweetening agent, reduced the running cost of biogas desulfurization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, a kind of changing food waste is produced the desulfurizer of biogas, include treating pond 1, in treating pond 1, being provided with security device 3 is connected, the entrance of security device 3 is connected with dry-type methane storage tank 5 with no pressure, make-up pipe 4 provides supplementary feed to security device 3, the firedamp drainage mouth of security device 3 is connected with biological desulphurization tower 6 by pipeline, on the pipeline between security device 3 and biological desulphurization tower 6, be connected with air supply pump 7, recycle pump 8 has been delivered to the 6 top circulations of biological desulphurization tower by the circulation fluid in biological desulphurization tower 6 and has been sprayed, the biogas delivery port of biological desulphurization tower 6 is connected with the inlet mouth of dry-type desulfurizing tower by pipeline, the venting port of dry-type desulfurizing tower is connected with using appts.
Described biological desulphurization tower 6 bottoms are connected with nutrition agent pipeline.
The inner sweetening agent of filling iron oxides of described dry-type desulfurizing tower.
The effect of the utility model security device is:
The structure of unpowered agitation fermentor tank is divided into upper chambers and bottom compartment, and the methane accumulation that fermentation produces, in bottom compartment, promotes bottom fermented liquid in tank and moves to upper chambers along centre pipe; When biogas pressure reaches set(ting)value in tank, automatically open security device 3 at the valve connecting on the connecting leg of tank body upper and lower part, be stored in the High-pressure Marsh Gas gas of bottom, outwards discharge on tank top by fermentation; The fermented liquid of upper chambers, under action of gravity, moves downward along centre pipe simultaneously, realizes the object that pot liquid stirs.It is its sharpest edges that whipping process does not need electric power energy.Meanwhile, its structure has guaranteed that fermentor tank is difficult for producing scum silica frost and crust is existing.
Principle of work of the present utility model is:
Biogas in dry-type methane storage tank with no pressure is inputted by biological desulphurization tower bottom through piping, is filled with the carrier-filler that maintains microorganism existence in biological desulphurization tower;
Spray on the top that circulation fluid in biological desulphurization tower is delivered to biological desulphurization tower by shifting pump, forms adverse current with the biogas of bottom input, and now in circulation fluid, microorganism carries out biological respinse by hydrogen sulfide hydrogen sulfide is decomposed.For the necessary oxygen of breathing of microorganism is provided, adopt air supply pump 7 to injecting air in biological desulphurization tower, to maintain oxygen concentration;
Through biological desulphurization tower biogas after treatment, directly enter and in dry-type desulfurizing tower, carry out desulfurization processing again, the inner iron oxides of filling of dry-type desulfurizing tower obtains sweetening agent, when biogas is by packing layer, sweetening agent is changed to iron sulphide by the hydrogen sulfide in biogas, thereby removes the hydrogen sulfide in biogas.The concentration of the hydrogen sulfide in the biogas after dry-type desulfurizing tower desulfurization is 1ppm.
