Embodiment Construction
[0024] see figure 1 , The vehicle-used compressed bio-natural gas production equipment of the present invention is composed of a pretreatment system, an anaerobic fermentation tank, a desulfurization system, a deoxygenation system, a decarbonization system, a dehydration system, a compression system, and a waste heat utilization device. After the biomass raw material is processed by the pretreatment system, anaerobic fermentation tank, desulfurization system, deoxygenation system, decarbonization system, dehydration system, and compression system, the compressed bio-natural gas for vehicles is output. The waste heat utilization device is used to collect the waste heat generated by the deoxygenation system, decarbonization system, dehydration system or compression system, and the collected waste heat is used to increase the temperature and heat preservation of the anaerobic fermentation tank. The waste heat utilization device adopts a water-cooling method, that is, the cold wa...

The invention relates to production equipment and a production method of compressed biological natural gas for a vehicle. The production equipment comprises a pretreatment system, an anaerobic fermentation tank, a desulfurization system, a deoxidation system, a decarbonization system, a dewatering system, a compression system and a waste heat utilization device, wherein after the biomass raw material is treated by the pretreatment system, the anaerobic fermentation tank, the desulfurization system, the deoxidation system, the decarbonization system, the dewatering system and the compression system, the compressed biological natural gas for the vehicle is output; and the waste heat utilization device is used for collecting the waste heat generated by the deoxidation system, the decarbonization system, the dewatering system or the compression system, and the collected waste heat is used for heating and insulating the anaerobic fermentation tank. In the invention, the waste heat generated in biogas deoxidation, decarbonization, dewatering and compression processes is utilized by the heat exchanger to convert cold water into high-temperature hot water by a heat exchanger, and the high-temperature hot water is used for heating and insulating the anaerobic fermentation tank, thereby realizing the energy gradient and comprehensive utilization of the production equipment of the compressed biological natural gas for the vehicle, and improving the integral heat utilization efficiency of the system.
Description
technical field [0001] The invention belongs to the field of energy efficiency improvement, and in particular relates to a vehicle-used compressed bio-natural gas production equipment and a production method. Background technique [0002] According to the 2009 national rural renewable energy statistics, by the end of 2008, the total annual biogas production was 12.118 billion cubic meters, equivalent to 9% of the natural gas consumption in that year. Considering technical feasibility and resource competitiveness, the biomass resources that can be used to produce biogas in my country are equivalent to about 199 billion cubic meters of biogas equivalent, equivalent to 120 billion cubic meters of natural gas, which is equivalent to 1.5 times of my country's natural gas consumption of 80.7 billion cubic meters in 2008. However, the current utilization methods of biogas are mainly direct combustion and biogas power generation, and its utilization value is low, and the income of ...
