Abstract

The invention provides a domestic marsh gas combined heat and power generation device. The domestic marsh gas combined heat and power generation device comprises a first burning chamber, a thermo-acoustic engine and a bothway turbine power generation device; the first burning chamber is used for burning combustible gas to obtain heat, a heating device is arranged inside the first burning chamber and is connected with the thermo-acoustic engine through a thermal bridge, the thermo-acoustic engine is combined with the bothway turbine power generation device to form a thermo-acoustic power generation device, and meanwhile, the thermo-acoustic engine is connected with a water way in a contact manner. The domestic marsh gas combined heat and power generation device is provided with the bothwayturbine power generation device, the structure is simple, running is reliable, the overall machine cost is low, meanwhile, waste heat of the thermo-acoustic engine is used, the heat efficiency can befurther improved, the thermo-acoustic power generation scale can be flexibly designed according to actual needs, and the device is suitable for small and medium house type domestic systems.

Description

technical field [0001] The invention relates to the technical field of new energy applications, and more specifically, to a domestic biogas cogeneration device. Background technique [0002] Renewable energy is an important energy source for sustainable development, and biogas power generation technology is a new technology for comprehensive utilization of energy that integrates environmental protection and energy saving. It uses a large amount of organic waste (such as feces, straw, urban garbage, sewage, etc.) in industry, agriculture or urban life to produce biogas through anaerobic fermentation, uses the biogas on the engine, and is equipped with a comprehensive power generation device. It is an important way to effectively use biogas to generate electricity and heat. At present, there are a huge number of domestic biogas users, and about 40% of the 200 million rural households use domestic biogas digesters. If the biogas can be processed and utilized, tens of billions...
