Description

Technical Field

[0001] The utility model relates to the technical field of wet gas storage tank devices, and particularly relates to an adjustable-pressure wet gas storage tank. Background Technique

[0002] A wet gas storage tank is the simplest and most common type of gas storage tank, usually used for biogas storage. It consists of a water seal tank and a bell. The bell is a bottomless cylindrical container that can move up and down. Large and medium-sized biogas projects are one of the important means to solve energy and environmental pollution problems. In general biogas projects, wet gas storage tanks are used for biogas storage. During the use of the gas storage tank, due to operational errors or damage to equipment, pipelines, etc., problems such as excessive biogas and negative pressure often occur in the wet gas storage tank. These problems easily lead to deformation and damage of the gas storage tank. The existing biogas gas storage tank has the bell set in a form that can slide up and down freely. When biogas is introduced into the gas storage tank, the bell moves upward to balance with the external atmospheric pressure. When the biogas in the bell is led to users and used by them, the gas in the gas storage tank decreases, and the bell moves downward to maintain balance with the external atmospheric pressure.

[0003] For example, an automatically adjustable-pressure wet gas storage tank with the publication number CN207990186U consists of components such as a water seal pool, a bell, and a vent pipe. The water seal pool adopts a steel-concrete structure and is provided with a heat preservation layer. An air inlet pipe and an air outlet pipe are provided in the water seal pool. The bell and the water seal pool are connected through a guide rail connecting piece. Each wet gas storage tank is evenly arranged with a group of guide rail connecting pieces. The guide rail connecting piece consists of an upper guide wheel, a lower guide wheel, and a guide rail. The bell is provided with an upper guide wheel and a lower guide wheel, and a counterweight is provided at the lower end to facilitate the lifting of the bell. A slider is evenly fixed on the inner wall of the bell, and the bottom end of the slider is connected to a spring and fixed at the bottom of the water seal pool. Eight sliders are evenly arranged on the inner walls around the bell and fixed at the bottom of the water seal pool through springs to facilitate pressure regulation during the lifting process of the bell.

[0004] The above device is connected by a spring fixed at the bottom of the water seal pool and the bottom end of the slider inside the bell. The bell can be automatically adjusted through the slider with a spring, which solves the problem of inconvenience to users caused by insufficient or excessive pressure. Moreover, the wet gas storage tank has a simple structure, is easy to manufacture, and has advantages such as environmental protection, energy conservation, safety and reliability, long service life, and low cost. However, since the automatic adjustment device of the device mainly adjusts itself through the setting of the spring, it brings an extreme value of the internal air pressure. When exceeding this limit, it may cause damage to the spring or make the elastic deformation effect worse and unable to rebound. It is relatively unsafe to set the main automatic adjustment on the spring effect. Content of the Utility Model

Detailed implementation mode

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 to 2 , the present invention provides a technical solution:

[0019] Figure 1 This is the front overall view of the device. The main body is the gas storage tank 4. A curved cover 5 is arranged at the upper end of the gas storage tank 4. The curved cover 5 provides an internal sealed space for the gas storage tank 4. And an air transmission pipe 7 is arranged at the upper end of the curved cover 5. At the same time, a fixed joint 6 is installed outside the air transmission pipe 7. An outer convex layer 9 is arranged at the upper end of the fixed joint 6. The setting of the outer convex layer 9 facilitates the user to move and fix. And a sealing plate is arranged in the middle of the air transmission pipe 7. At the same time, an engaging layer is arranged on the inner wall of the air transmission pipe 7 to facilitate fixed connection with the pipeline for transporting biogas required, preventing gaps or leaks in the transmission connection from causing internal biogas leakage. An air transmission end 8 is installed in the center of the sealing plate. And an air transmission interface is arranged in the middle of the air transmission end 8. The air transmission end 8 arranged in the middle is used to transmit biogas. An interpenetrating pipe 2 is arranged on the side surface of the gas storage tank 4. And an air pressure gauge 3 is installed outside the interpenetrating pipe 2. At the same time, a fixed rod is installed on the back side of the air pressure gauge 3 to connect to the surface of the gas storage tank 4. In addition, the air pressure value is displayed on the air pressure gauge 3 through the airbag detection end installed inside the interpenetrating pipe 2. The accurate air pressure gauge 3 is displayed through the numbers set on the side. A transmission line pipe is arranged at the lower end of the air pressure gauge 3. And an air vent end is installed at the lower end of the transmission line pipe. At the same time, an air pump 1 is connected to the right side of the air vent end. A control end is arranged at the upper end of the air pump 1. The numerical signal displayed by the air pressure gauge 3 is transmitted to the air vent end through the transmission line pipe. And the air pump 1 connected to the back side of the air vent end is controlled to transmit the signal to the upper control end. When the received signal exceeds the limit, the air pump 1 will be turned on to transport gas into the interior to increase the internal air pressure and balance the negative air pressure state;

[0020] Figure 2This is a side view of the balance pipe 15 of the device. The main body is the gas storage tank 4. The balance pipe 15 is arranged on the other side of the gas storage tank 4. Derivative pipes are installed on both sides at the upper end of the balance pipe 15. At the same time, a cover 13 is arranged at the top of the derivative pipe. A lower connecting plate is arranged at the lower end of the cover 13. An embedded spring 12 is arranged at the lower end of the lower connecting plate. At the same time, the embedded spring 12 is connected to the fitting end block 10. A side port is arranged inside the derivative pipe. A support column 11 passes through the side port and is connected to the upper end of the fitting end block 10. At the same time, a handle 14 is arranged at the upper end of the support column 11. The upper derivative end is provided for placing the fitting end block 10. The main material of the fitting end block 10 is plastic material, and its shape is set to engage with the inner wall of the balance pipe 15 to ensure that there is no gap in its joint. When the internal air pressure in one gas storage tank 4 increases, it will cause the fitting end block 10 to move upward. Through the connection of the support column 11, the fitting end block 10 on the other side is driven to move within the range of the side port. When the fitting end block 10 moves to a certain position, the two ends will be connected to achieve the air pressure balance effect, so as to adjust the internal high air pressure of the device. And by increasing the number of connected gas storage tanks 4, the adaptability effect is better.

[0021] During actual use, through the connection on both sides of the device, when the air pressure is too low, the numerical signal of the air pressure gauge 3 is transmitted to the control end, and the internal air pressure is increased to the balanced air pressure value through the gas transmission of the air pump 1. When the air pressure is too high, the fitting end block 10 arranged inside it moves upward through the balance pipe 15 connected on one side, driving the other side to move so that the middle is connected to balance the internal high pressure. When the number of connected gas storage tanks 4 is large, its self-balancing effect is stronger.

[0022] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
