Method and apparatus for employing human feces methane and solar energy as energy source of combined heat and power system

Abstract

The invention discloses a method of using firedamp and solar energy as the power resource of thermoelectric generating system. Wherein, using solar energy collector to attain the hot water above 100Deg. C; using heat exchange tube to heat the firedamp generator to keep the ferment temperature inside the firedamp generator at 55-60Deg. C, to attain the high-quality firedamp while the firedamp generate rate is 2.5-3.5m3 / m3 each day; the firedamp can be used as the power resource of thermoelectric generator. Said device comprises a solar energy collector, a firedamp reactor, and a steam generator. The invention realizes generating firedamp at high temperature to confirm the energy of ferment pool, while the firedamp yield of people shit is 0.43m3 / kg, the firedamp of raise yield is 0.12-0.35m3 / kg; and the firedamp yield at high temperature as 45-55Deg. C inside the firedamp ferment pool (digest device) is 2.5-3 times of ferment pool at lower temperature (<35Deg. C). The invention can be used at the industry workshop and the country.

Description

Technical field: [0001] The present invention relates to a method and equipment for using human excrement biogas and solar energy as energy sources for a combined heat and power system. The method and equipment are particularly realized by the combined energy supply of a human excrement biogas fermentation tank with high temperature and high gas production rate and CPC type medium-grade solar energy. Cogeneration method. Background technique: [0002] China is a country with a large population. For a long time, people have ignored the potential energy value of human excrement, and most of them are discharged as waste, which not only wastes energy, but also pollutes the environment. The current biogas digesters are generally normal temperature or variable temperature biogas digesters, and the production rate is relatively low and unstable, which is not suitable for industrial continuous production. However, the method of introducing solar energy into the biogas digester to ob...

Problems solved by technology

[0002] China is a country with a large population. For a long time, people have ignored the potential energy value of human excrement, and most of them are discharged as waste, which not only wastes energy, but also pollutes the environment.

The current biogas digesters are generally normal temperature or variable temperature biogas digesters, and the production rate is relatively low and unstable, which is not suitable for industrial continuous production. However, the method of introducing solar energy into the biogas digester to obtain higher gas production rate is currently limited to small solar energy such as plate collectors. The system does not require temperature control, which limits the working performance and application range of solar biogas generators
