NOVELTY - A distributed-type cooling heating and power system comprises marsh gas collecting device (1), marsh gas purification device (3), fuel gas internal combustion engine (5), cold water electric generator (16), fumed hot water and lithium bromide absorption-type chiller-heater unit (21), heat exchange device, and cooling tower. The marsh gas collecting device is connected with fuel gas internal combustion engine. The internal combustion engine uses fuel gas and marsh gas to produce power and is connected to cold generator water to generate power.    USE - Distributed-type cooling heating and power system used for producing biogas (claimed).    ADVANTAGE - The system is continuous, stable, and efficient, fully recycles biomass methane fermentation of organic matter, and effectively alleviates air pollution.    DETAILED DESCRIPTION - A distributed-type cooling heating and power system comprises marsh gas collecting device (1), marsh gas purification device (3), fuel gas internal combustion engine (5), cold water electric generator (16), fumed hot water and lithium bromide absorption-type chiller-heater unit (21), heat exchange device, and cooling tower. The marsh gas collecting device is connected with fuel gas internal combustion engine. The internal combustion engine uses fuel gas and marsh gas to produce power and is connected to cold generator water to generate power. The internal combustion engine and fumed hot water and lithium bromide absorption-type chiller heater unit produce high temperature flue gas. The fumed hot water and lithium bromide absorption-type chiller heater unit and water-cooled heat exchangers are connected with generator device.
