Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing biogas dehydration methods mainly include the throttling expansion cooling dehydration method and the post-pressurization cooling method. Both methods require additional booster equipment, and the condenser must be installed at the lowest point of the pipeline. , resulting in low condensation efficiency, which cannot meet the high intake requirements of the generator set, and provides a biogas rotary condensation device

specific Embodiment approach 1

[0014] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment. This embodiment includes a condenser 1, a screw shaft 2, a drive shaft 3, a motor 4, a driven shaft 5, a baffle 6 and a biogas output pipe 7. The condenser 1 is a cylindrical structure, and the baffle The plate 6 is horizontally arranged in the condenser 1, the condensate bin 1-1 is above the baffle 6, and the condensate collection bin 1-2 is below the baffle 6, and the screw shaft 2 is set in the condensate bin 1-2. 1, the upper end of the screw shaft 2 is the biogas inlet 2-1 and passes through the top of the condenser 1, the upper end of the screw shaft 2 passes through the baffle plate 6 and is located in the condensed water collection bin 1-2, and the driving shaft 3 is installed through a bearing On the top of the condenser 1, the input end of the driving shaft 3 is connected to the output end of the motor 4, the output end of the driving shaft 3 is connected to the screw s...

specific Embodiment approach 2

[0015] Specific implementation mode two: combination figure 1 This embodiment is described. The difference between this embodiment and the first embodiment is that it also adds a liquid level gauge 8, which is arranged on the side wall of the condenser 1 and located on the upper part of the condensed water collection bin 1-2. The liquid level gauge 8 is used to monitor the liquid level of the condensed water, and when the liquid level of the condensed water reaches a certain height, it will be discharged through the drain port 1-5 of the condenser. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0016] Specific implementation mode three: combination figure 2 Describe this embodiment, the difference between this embodiment and specific embodiment one is that it also adds an exhaust pipe 9, and the exhaust pipe 9 is arranged in the condensate tank 1-1, and the upper end of the exhaust pipe 9 passes through the condenser 1 The top of the exhaust pipe 9 passes through the baffle plate 6 and is located in the condensed water collection bin 1-2 at the lower end. When emergencies such as excessive pressure in the condensed water collection bin 1-2 occur, the exhaust pipe 9 is used to discharge the biogas in the condensed water collection bin 1-2. Other compositions and connections are the same as those in Embodiment 1 or 2.

[0017] Working principle of the present invention:

[0018] The condensate enters the condensate bin 1-1 from the condensate inlet 1-3 and fills up the condensate bin, biogas enters the screw shaft 2 from the biogas inlet 2-1, starts the motor 4, and...

The device provided by the invention is suitable for being used in a methane power generation technology of a large-scale methane project.

Description

technical field [0001] The invention relates to a condensation device, in particular to a biogas rotary condensation device. Background technique [0002] The biogas power generation project is a system project that takes anaerobic digestion as the core technology, forms terminal products with biogas power generation, and integrates manure treatment, biogas production and power generation, and biogas resource utilization. However, due to the high requirements of biogas generator sets on the quality of biogas, especially in cold regions such as Heilongjiang, the power generation cost and power generation effect of biogas power generation projects cannot be well guaranteed. [0003] The main components of biogas are methane and carbon dioxide, and its calorific value is about 20-25MJ / m 3 . In the biogas project, the temperature of the biogas produced is different depending on the process, mostly around 30°C and 50°C, and contains a large amount of water vapor, which will cau...
