Abstract

The invention provides a biogas slurry decarbonization and deamination combined system. The system comprises a preheater (1), a decarbonization tower (2), a deamination tower (4), a condenser (5), an ammonia water storage tank (6) and a pipeline (7), wherein the preheater (1) preheats a biogas slurry raw material and feeds the biogas slurry raw material into the decarbonization tower (2), and the decarbonized biogas slurry raw material enters the deamination tower (4), is brought out by water vapor in the deamination tower (4), then is cooled by the condenser (5) and enters the ammonia water storage tank (6). By virtue of equipment designed on the device, ammonia nitrogen in biogas slurry can be effectively removed, and energy saving and environment protecting effects are achieved; meanwhile, the whole device is also easy to control and can be further popularized and applied.

Description

technical field [0001] The invention relates to the field of biogas slurry decarburization, in particular to a biogas slurry decarburization combined with deamination system. Background technique [0002] With the continuous development of the current social economy, people's living standards are also constantly improving, and higher production requirements are also put forward for traditional manufacturing industries. [0003] A large amount of high-concentration wastewater will be produced in the production process of alcohol fermentation. After two-stage anaerobic fermentation to produce biogas, the wastewater COD is about 2000mg / L and contains 300-500mg / L ammonia nitrogen. If these wastewater with high COD and ammonia nitrogen are discharged directly, It will cause a large number of aquatic organisms to die and have a serious impact on the ecosystem; in addition, the country vigorously promotes energy conservation and emission reduction policies, and reduces the ammonia ...
