In this detailed description, the subject of the invention is explained with examples that do not have any limiting effect only for a better understanding of the subject.
The invention relates to a biogas production system for producing biogas from a mixture containing animal waste and water.
Referring to Figure 1 , the said biogas system (10) comprises a mixture storage unit (100). There is a supply line (120) provided on the mixture storage unit (100). The said supply line (120) allows the mixture of animal waste and water to be transferred into the mixture storage unit (100).
There is a waste drainage line (1 10) to ensure that waste is drained from the mixture storage unit (100). The said waste is generated as a result of obtaining biogas from the mixture. There is a hot water line (130) for adjusting the temperature of the mixture placed inside the mixture storage unit (100). The said hot water line (130) is disposed to surround the storage unit. Thus, it is ensured that the temperature of the mixture storage unit (100) is kept constant. A constant temperature is required to obtain biogas from the mixture contained in the mixture storage unit (100). The hot water line (130) ensures that this temperature is kept constant. In a possible embodiment of the invention, the water temperature in the hot water line (130) is kept constant at 37 degrees Celsius.
There is a solar collector (240) for supplying water to the hot water line. In a possible embodiment of the invention, it is preferred to use the vacuum tube solar collector (240) as the solar collector (240).
There is a temperature sensor (310) for measuring the temperature of the water in the solar collector (240). The biogas production system comprises a processor (300) configured to receive data from the said temperature sensor (310). The said temperature sensor (310) continuously measures the temperature of the water so that when the water cools, it is transmitted from a cold water transmission line (170) to the solar collector (240). After the cold water is heated in the solar collector (240), it is sent back to the mixture storage unit (100) from a hot water transmission line (160).
There is a mixing unit (140) for increasing the yield of biogas obtained from the mixture contained in the mixture storage unit (100). In a possible embodiment of the invention, the serpentine rubber material is used as the said mixing unit (140). (10) The mixing unit (140) is also configured to operate at certain times of the day with a timer. Therefore, the mixture is not constantly mixed. Thus, this saves energy.
Referring to Figure 2, there is a gas storage unit (200) in the biogas system (10). The biogas produced in the mixture storage unit (100) is stored in the said gas storage unit (200). It is transmitted from a gas transmission line (150) to the gas storage unit (200) produced in the mixture storage unit (100). In a possible embodiment of the invention, Teflon material up to 16 bar is used as the said gas transmission line (150).
The gas storage unit comprises a first liquid reservoir and a second liquid reservoir intertwined. The said second liquid reservoir is disposed of inversely in the first liquid reservoir. The second liquid reservoir contains water filled up to half of the second liquid reservoir. This seals the second liquid reservoir and the first liquid reservoir. Thus, the spread of the produced biogas to the environment is prevented. The biogas transferred from the gas transmission line (150) to the gas storage unit (200) is temporarily stored between the first liquid reservoir and the second liquid reservoir.
There is a floating cover (210) on the gas storage unit. The floating cover (210) is disposed of in connection with the gas storage unit (200). There is a switching element (220) on the floating cover (210). The said switching element (220) allows the gas in the gas storage unit (200) to transmit to a washing unit (230).
If gas is filled into the gas storage unit (200), the accumulated gas exerts a thrust force on the floating cover (210). The floating cover (210) moves upwards with the effect of the applied pushing force. Thus, the floating cover (210), which moves upwards, allows one to measure how much gas is stored in the tank.
The biogas coming into the said washing unit (230) is purged here. In a possible embodiment of the invention, it is preferred to use a metal-absorbing material as the washing unit (230). The gas coming to the washing unit (230) reacts with the material containing the metal absorbent property. The hydrogen sulfide is purified from the reacting gas.
Referring to Figure 3, there is a provided biogas storage unit (250) connected to the gas storage unit (200). In the biogas storage unit (250), the biogas passing through the washing unit (230) is stored for use. An exemplary operating scenario of the invention is described as follows;
It is ensured that biogas production is performed by using animal wastes in a biogas production system. The collected animal wastes are preferably pumped from the supply line (120) to the mixture storage unit (100), half of which is water. The temperature of the mixture storage unit (100) is raised using the hot water line (130) provided in the mixture storage unit (100). The water in the hot water line (130) is heated via the solar collector (240). Thus, the necessary heat for obtaining biogas from the mixture is provided by utilizing solar energy. The temperature of the mixture storage unit (100) is controlled by the processor (300). The processor (300) ensures that the temperature data received from the temperature sensor (310) is kept at a predetermined temperature value. The controller ensures that the water flow through the hot water transmission line (160) and the cold water transmission line (170) is controlled to ensure that the temperature is kept constant. The processor (300) enables the mixing unit (140) to be operated at predetermined periods. Biogas production efficiency is increased using the mixing unit (140). The biogas formed over time in the mixture storage unit (100) is pressurized to the gas storage unit (200) through the gas transmission line (150). With the separation of biogas from the face, waste is generated in the mixture storage unit (100). The said waste is drained from the waste drainage line (1 10).
The gas from the gas transmission line (150) accumulates between the first liquid reservoir and the second liquid reservoir. The gas accumulated in the second liquid reservoir moves upwards by applying the thrust force to the liquid in the first liquid reservoir. Depending on this movement, the floating cover (210) provided on the second liquid reservoir moves upwards with the gas. Thus, it is determined that gas accumulates in the second liquid reservoir as much as the displacement amount of the floating cover (210).
If the gas accumulated in the second liquid reservoir reaches a predetermined level, the floating cover (210) enables the switching element (220) to come to the open position. The gas is transmitted to the washing unit (230) when the switching element (220) is in the open position. The gas entering the washing unit (230) reacts with the metal-absorbing material. Here, hydrogen sulfide is purified from the gas that reacts. Thus, biogas is obtained. The resulting biogas is stored for use in the gas storage unit (200).
In an exemplary embodiment of the invention, biogas is obtained from animal wastes collected by a farmer. The farmer ensures that the collected animal wastes are transferred from the supply unit to the mixture storage unit (100) as a mixture with water. The gas formed over time in the mixture storage unit (100) is transmitted to the gas storage unit (200). The gas accumulated in the gas storage unit (200) is transmitted to the washing unit (230). Hydrogen sulfide is separated from the gas in the washing unit (230). The resulting biogas is used to operate a furnace. Thus, it is ensured that the obtained biogas can be used directly. The scope of protection of the invention is specified in the attached claims and cannot be limited to those explained for sampling purposes in this detailed description. It is evident that a person skilled in the art may exhibit similar embodiments in light of the above-mentioned facts without drifting apart from the main theme of the invention.
