Description

Technical Field

[0001] The utility model relates to the technical field of biogas collection of wastewater anaerobic tanks, in particular to a water seal system for an anaerobic tank. Background Art

[0002] The existing water seal system for an anaerobic tank includes: a water seal tank and a safety water seal tank. A certain height of stored water remains in both water seal tanks. The inlet pipe extends into the stored water, and the outlet pipe is reserved above the water surface.

[0003] The gas generated by anaerobic bacteria enters the bottom of the water seal tank through the inlet pipe opening of the water seal tank and submerges into the water. The gas accumulates in the upper space of the water seal tank and generates a certain pressure. Finally, the gas is discharged through the outlet pipe opening at the top of the water seal tank. When the gas is discharged and burned, if backfire occurs, the stored water in the water seal tank can cut off the connection, avoid the spread of backfire and protect the main equipment. At the same time, the water seal tank can also filter the gas through the stored water.

[0004] When the outlet pipe of the water seal tank is blocked or closed, the biogas generated by the anaerobic reactor enters the safety water seal tank and is discharged into the atmosphere. However, the existing water seal tank and safety water seal tank are not directly connected, and it is necessary to manually operate the valve to switch the gas path. This process increases the workload of manual operation, and if the operation is not timely, it will cause the gas not to be discharged, resulting in potential safety hazards.

[0005] Therefore, there is an urgent need for a water seal system for an anaerobic tank that can solve one or more of the above problems. Summary of the Utility Model

[0006] To solve one or more problems existing in the prior art, the utility model provides a water seal system for an anaerobic tank. The technical solution adopted by the utility model to solve the above problems is: a water seal system for an anaerobic tank, which includes: a water seal tank, the water seal tank stores water, the water seal tank is connected to the outlet end of the inlet pipe, the outlet end of the inlet pipe is immersed in the stored water of the water seal tank, and the inlet end of the inlet pipe is connected to the first outlet end of the anaerobic tank;

[0007] The water seal tank is connected to the inlet end of the exhaust pipe, the inlet end of the exhaust pipe is arranged above the liquid level of the stored water, and the outlet end of the exhaust pipe is connected to the subsequent treatment facility;

[0008] A safety water seal tank, the safety water seal tank stores water, the safety water seal tank is provided with a discharge port, the discharge port is arranged above the liquid level of the stored water, the safety water seal tank is connected to the outlet end of the connecting pipe, the outlet end of the connecting pipe is immersed in the stored water of the safety water seal tank, and the inlet end of the connecting pipe is connected to the exhaust pipe;

[0009] The safety water seal tank is connected to the outlet end of the safety inlet pipe. The outlet end of the safety inlet pipe is immersed in the stored water of the safety water seal tank, and the inlet end of the safety inlet pipe is connected to the second outlet end of the anaerobic tank.

[0010] In some embodiments, corresponding pressure valves may be installed on the inlet pipe, the exhaust pipe, the connecting pipe, the discharge port, and the safety inlet pipe.

[0011] During implementation, pressure adjustment is performed by adjusting the stored water volume and the immersion height of the pipe body, such that the pressure at the outlet end of the exhaust pipe is less than the pressure at the outlet end of the connecting pipe (the difference is within 5 kPa), and the pressure at the inlet end of the connecting pipe is less than or equal to the pressure at its connection end with the exhaust pipe, thereby preventing the stored water in the safety water seal tank from flowing back into the exhaust pipe;

[0012] and such that the pressure at the outlet end of the safety inlet pipe is greater than or equal to the sum of the pressure at the outlet end of the inlet pipe and the pressure at the outlet end of the connecting pipe.

[0013] The technical effect achieved by the present utility model is that when the outlet end of the exhaust pipe is closed or blocked, gas can automatically enter the safety water seal tank and be discharged through the discharge port, thereby protecting the safety of the facility. Moreover, by providing the safety inlet pipe, the efficiency of gas entering the safety water seal tank can be increased when the gas pressure continues to increase, thereby accelerating the gas discharge efficiency and ensuring that the air pressure inside the facility always remains within a safe range.

[0017] To make the above objects, features, and advantages of the present utility model more comprehensible, the following describes the specific embodiments of the present utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from this description. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0018] Such as Figure 1As shown in the figure, the utility model discloses a water seal system for an anaerobic tank, which includes: a water seal tank 2 storing water, the water seal tank 2 is connected to the outlet end of an intake pipe 1, the outlet end of the intake pipe 1 is immersed in the stored water of the water seal tank 2, and the intake end of the intake pipe 1 is connected to the first outlet end of the anaerobic tank;

[0019] The water seal tank 2 is connected to the intake end of an exhaust pipe 3, the intake end of the exhaust pipe 3 is arranged above the liquid level of the stored water, and the outlet end of the exhaust pipe 3 is connected to a subsequent treatment facility;

[0020] A safety water seal tank 5 storing water, the safety water seal tank 5 is provided with a discharge port 6 arranged above the liquid level of the stored water, the safety water seal tank 5 is connected to the outlet end of a connecting pipe 4, the outlet end of the connecting pipe 4 is immersed in the stored water of the safety water seal tank 5, and the intake end of the connecting pipe 4 is connected to the exhaust pipe 3;

[0021] The safety water seal tank 5 is connected to the outlet end of a safety intake pipe 7, the outlet end of the safety intake pipe 7 is immersed in the stored water of the safety water seal tank 5, and the intake end of the safety intake pipe 7 is connected to the second outlet end of the anaerobic tank.

[0022] Specifically, the intake pipe 1, the exhaust pipe 3, the connecting pipe 4, the discharge port 6 and the safety intake pipe 7 can be installed with corresponding pressure valves to achieve automatic switching of on and off;

[0023] Furthermore, the water seal tank 2 and the safety water seal tank 5 can be installed with pressure sensors to detect the gas pressure in the tanks;

[0024] The water seal tank 2 and the safety water seal tank 5 can be installed with water replenishing and draining devices to realize the replacement, discharge and replenishment of the stored water;

[0025] The intake pipe 1, the connecting pipe 4 and the safety intake pipe 7 can be installed with liquid level sensors to detect the liquid level of the pipe bodies, and further assist in judging the current pressure state in the tanks.

[0026] During implementation, the pressure is adjusted by adjusting the stored water volume and the immersion height of the pipe bodies. When operating normally for exhaust, the pressure at the outlet end of the exhaust pipe 3 is made less than the pressure at the outlet end of the connecting pipe 4 (the difference is within 5 kPa), so as to ensure that the gas in the water seal tank 2 does not enter the safety water seal tank 5 under normal operating conditions;

[0027] Furthermore, the pressure at the intake end of the connecting pipe 4 is made less than or equal to the pressure at its connection end with the exhaust pipe 3, so as to prevent the stored water in the safety water seal tank 5 from flowing back into the exhaust pipe 3;

[0028] and making the pressure at the outlet end of the safety intake pipe 7 greater than or equal to the sum of the pressure at the outlet end of the intake pipe 1 and the pressure at the outlet end of the connecting pipe 4, ensuring that when the outlet end of the exhaust pipe 3 is blocked or closed, the gas can not only enter the safety water seal tank 5 through the connecting pipe 4 for discharge, but also enter the safety water seal tank 5 through the safety intake pipe 7 for discharge, so that the gas can be discharged efficiently, and finally protect the facility.

[0029] During normal operation, the outlet end of the exhaust pipe 3 is open, and the gas overcomes the pressure at the outlet end of the intake pipe 1 and enters the water seal tank 2, and is discharged through the exhaust pipe 3 for use;

[0030] When the exhaust pipe 3 is blocked or closed, the gas overcomes the pressure at the outlet end of the intake pipe 1 and enters the water seal tank 2, and then the gas in the water seal tank 2 overcomes the pressure at the outlet end of the connecting pipe 4 and enters the safety water seal tank 5, and is discharged through the discharge port 6. If the gas pressure continues to increase, the gas in the anaerobic tank overcomes the pressure at the outlet end of the safety exhaust pipe 7 and enters the safety water seal tank 5, and then is discharged through the discharge port 6, realizing dual-channel discharge, ensuring that the gas generated by the anaerobic tank can be discharged in a timely and efficient manner, and thus protecting the safety of the entire facility.

[0031] In summary, when the outlet end of the exhaust pipe is closed or blocked, the gas can automatically enter the safety water seal tank and be discharged through the discharge port, thereby protecting the safety of the facility. Moreover, by setting the safety intake pipe, the efficiency of the gas entering the safety water seal tank can be increased when the gas pressure continues to increase, and thus the discharge efficiency of the gas can be increased, so as to ensure that the air pressure in the facility is always within the safe range.
