Embodiment 1

[0034] Embodiment 1: the volume of the fermentation tank is 0.5 cubic meters, the anaerobic reactor is 3.3 cubic meters, and the temperature is 15 to 50 degrees Celsius. Put into domestic waste, cattle, horses, pigs, human urine and stool, and the minimum biogas pressure is 3.3 * 4 = 13kpa, the highest is 3.3×20=66kPa.

Embodiment 2

[0035] Embodiment 2: The fermentation tank is 0.036 cubic meters, and the reactor is a stainless steel plate water tower with a diameter of 0.8 meters, a height of 1.3 meters, and a volume of 0.65 cubic meters. After 18 days of fermentation, the biogas can be used, and the volumetric gas production rate is 2 times, which is 16kpa during the day , 12kpa at night, 28kpa pressure gauge in 24 hours, with a volume of 0.65 cubic meters. 1-16kpa biogas pressure can be produced every day.

[0036] Send the biogas generated above to Guangxi Civil Fuel and Gas Products Quality Supervision and Inspection Station for inspection, and produce the inspection report (No. H2009-070) showing the main biogas indicators as follows:

[0037]

[0038] Generally, the content of biogas methane is 55% to 70%, the content of carbon dioxide is 28% to 44%, and the average content of hydrogen sulfide is 0.034%, while the methane concentration (73.54%) produced by the present invention is higher than it...

Abstract

The invention relates to a method for efficiently producing marsh gas and a device thereof. The method comprises the following steps: mainly using urban domestic garbage and rural waste as raw materials; putting the domestic garbage in a fermentation vat for primary corruption; then, conveying pretreated fermented liquid to an anaerobic reactor to ferment and generate the marsh gas; conveying devulcanized marsh gas to a cooker for combustion and use; and conveying liquid in the anaerobic reactor to the fermentation vat again. The device is characterized in pipeline design; an outlet pipeline of the fermentation vat is respectively communicated with a middle pipeline, a top pipeline and a bottom pipeline of the anaerobic reactor; and each pipeline is provided with a pipeline switch which can be opened or closed as required to achieve the functions of the reactor, such as automatically flushing, returning the liquid of the reactor to the fermentation vat, automatically discharging sewageand pollution, and the like. The invention improves the organic load rate and the processing efficiency of the reactor and has the advantages of easy cleaning, convenient pollution discharge and highmarsh gas production efficiency; and the produced marsh gas has high methane concentration and extremely low sulfureted hydrogen concentration, thereby being a favorable clean power source.

Description

technical field [0001] The invention relates to a method for biogas production and a device for producing biogas using the method. Background technique [0002] Biogas is a mixed gas. Its main component is methane, followed by carbon dioxide, hydrogen sulfide (H2S), nitrogen and other components. %, the average hydrogen sulfide content is 0.034%. [0003] According to local use requirements and conditions such as temperature and geology, the types of household biogas digesters include hydraulic pools with fixed arch covers, hydraulic pools with large uncovered covers, hanging tube hydraulic pools, meandering cloth hydraulic pools, Although there are various types of top return hydraulic pools, separated floating cover pools, semi-plastic pools, all-plastic pools and tank pools, they are generally composed of hydraulic biogas digesters, floating cover biogas There are four basic types of pools, semi-plastic biogas digesters and tank biogas digesters. [0004] The upper gas...
