Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection and safety equipment technology, and in particular to a rapid pressure regulating water seal device. Background Technology
[0002] In many industrial processes, such as chemical plants and coking plants, there are various gas pipeline systems. These gases may be toxic and harmful (such as hydrogen sulfide and chlorine) or flammable and explosive (such as methane and hydrogen). To prevent these gases from leaking into the surrounding environment and causing safety accidents and environmental pollution, an effective sealing device is needed. Water seal tanks are one such simple and effective device. For example, in a flare system, combustible gases discharged from various production units are transported to the flare for combustion through pipelines. In this process, to prevent flare backfire (the flame propagating backward along the pipeline) and gas leakage, water seal tanks are installed in the pipeline system. When the pressure in the flare system fluctuates, the water in the water seal tank can act as a buffer and seal, preventing gas from escaping.
[0003] The existing technical solutions mentioned above have the following drawbacks: the existing large water seal tanks require a large amount of water and take a long time to replenish, making them inconvenient to use and less practical. Utility Model Content
[0004] The purpose of this invention is to provide a rapid pressure regulating water seal device.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A rapid pressure regulating water seal device includes a water seal tank. An installation component is fixedly connected inside the water seal tank, and a standard flange is fixedly connected to the outside of the installation component. A first rubber air chamber and a second rubber air chamber are disposed inside the water seal tank between the installation components. Identical blind flanges are fixedly connected to both ends of the outside of the first rubber air chamber, and an identical standard flange is fixedly connected to one end of the outside of the second rubber air chamber, while an identical blind flange is fixedly connected to the other end of the outside of the second rubber air chamber.
[0007] By adopting the above technical solution, the rubber gas bag is installed inside the water seal tank and positioned below the liquid level. When air is blown into the gas bag, the gas bag expands rapidly, and the liquid level in the water seal tank also rises accordingly, thereby achieving the effect of different water levels and different pressures corresponding to different gas release processes.
[0008] Furthermore, a first air pipe is fixedly connected to the outside of the first rubber air bag, a first control valve is fixedly connected to the outside of the first air pipe, a second air pipe is fixedly connected to the outside of the second rubber air bag, a second control valve is fixedly connected to the outside of the second air pipe, and a third air pipe is provided on the outside of the second air pipe.
[0009] By adopting the above technical solution, when the rubber gas bag is evacuated, the rubber gas bag quickly retracts, and the liquid level in the water seal tank decreases accordingly. The final number of rubber gas bags can be calculated according to different working conditions based on the size of the water seal tank and the sealing pressure, so as to achieve the use under different working conditions. At least two rubber gas bags should be set. When the gas venting pressure does not change much, one rubber gas bag is used. When the gas venting pressure changes greatly, two rubber gas bags are started at the same time to achieve the effect of quickly adjusting the venting pressure.
[0010] Furthermore, a vacuum pump is installed on the outside of the third gas pipe, a gas tank is installed on the outside of the vacuum pump, a fourth gas pipe is fixedly connected to the outside of the gas tank, a locking bolt is inserted between the standard flange and the blind flange, and a locking nut is threaded on the outside of the locking bolt.
[0011] By adopting the above technical solution, the blind flange and the standard flange can be used together to separate the gap between the connection with the water seal tank and the gap between the connection of the two rubber air bags, so that the gap will not also form a vacuum. The vacuum pump can both evacuate the rubber air bag into a vacuum and blow air into the rubber air bag, realizing the function of one pump for multiple purposes and saving costs.
[0012] Furthermore, there are two symmetrically arranged mounting components, the standard flange and the blind flange are in contact with each other, and multiple locking bolts and locking nuts are provided, with three standard flanges and three blind flanges each.
[0013] By adopting the above technical solution, connection and installation are facilitated.
[0014] Furthermore, one end of the first air tube is connected to the interior of the first rubber air bag, one end of the second air tube is connected to the interior of the second rubber air bag, one end of the third air tube is connected to the vacuum pump, the other ends of the first air tube, the other ends of the second air tube, and the other ends of the third air tube are connected to each other through a T-connector, one end of the outer side of the fourth air tube is connected to the vacuum pump, and the other end of the outer side of the fourth air tube is connected to the air tank.
[0015] By adopting the above technical solution, the gas cylinder can effectively supply gas to the gas tank, realizing the functions of both supplying gas and creating a vacuum, which facilitates better adjustment and use.
[0016] In summary, the beneficial technical effects of this utility model are as follows:
[0017] The system utilizes rubber air bags, air tanks, vacuum pumps, air pipes, and control valves, which greatly saves water resources. At the same time, the water level in the water seal tank changes significantly in a short time, achieving rapid pressure sealing of the venting device. This greatly helps improve the overall process quality of the gas venting device and makes it easy to use. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.
[0022] Reference Figure 1-2A rapid pressure regulating water seal device includes a water seal tank 1. An installation component 2 is fixedly connected inside the water seal tank 1. A standard flange 3 is fixedly connected to the outside of the installation component 2. A first rubber air chamber 4 and a second rubber air chamber 5 are disposed inside the water seal tank 1 between the installation components 2. Identical blind flanges 6 are fixedly connected to both ends of the outer side of the first rubber air chamber 4. Identical standard flange 3 is fixedly connected to one end of the outer side of the second rubber air chamber 5, and identical blind flange 6 is fixedly connected to the other end of the outer side of the second rubber air chamber 5. A first air pipe 7 is fixedly connected to the outer side of the first rubber air chamber 4, and a first control valve 8 is fixedly connected to the outer side of the first air pipe 7. A second air pipe 9 is fixedly connected to the outer side of the second rubber air chamber 5, and a second control valve 10 is fixedly connected to the outer side of the second air pipe 9. A third air pipe 11 is disposed outside the second air pipe 9, and a vacuum pump 12 is disposed outside the third air pipe 11. An air tank 13 is disposed outside the vacuum pump 12, and a fourth air pipe 14 is fixedly connected to the outer side of the air tank 13. Locking bolts are inserted between the standard flange 3 and the blind flange 6. 15. A locking nut 16 is threaded onto the outer side of the locking bolt 15. The rubber air chamber is installed inside the water seal tank 1 and positioned below the liquid level. When air is blown into the air chamber, it expands rapidly, and the liquid level in the water seal tank 1 rises accordingly. This achieves the effect of different water levels and pressures corresponding to different gas release processes. When a vacuum is drawn into the rubber air chamber, it retracts rapidly, and the liquid level in the water seal tank 1 decreases accordingly. The final number of rubber air chambers can be calculated based on the water seal tank 1 and the sealing pressure, depending on the working conditions, to achieve different working conditions. For proper use, at least two rubber air bags should be installed. When the gas venting pressure does not change significantly, one rubber air bag can be used. When the gas venting pressure changes significantly, both rubber air bags should be activated simultaneously to achieve rapid adjustment of the venting pressure. The blind flange 6 and the standard flange 3 can be used together to separate the gap connected to the water seal tank 1 from the gap between the two rubber air bags, preventing the gap from becoming a vacuum. The vacuum pump 12 can both evacuate the rubber air bag into a vacuum and pump air into the rubber air bag, achieving a multi-purpose function and saving costs.
[0023] like Figure 1-2 As shown, there are two symmetrically arranged mounting components 2. The standard flange 3 and the blind flange 6 are in contact with each other. Multiple locking bolts 15 and locking nuts 16 are provided. There are three standard flanges 3 and three blind flanges 6. One end of the first air pipe 7 is connected to the inside of the first rubber air bag 4. One end of the second air pipe 9 is connected to the inside of the second rubber air bag 5. One end of the third air pipe 11 is connected to the vacuum pump 12. The other ends of the first air pipe 7, the second air pipe 9, and the third air pipe 11 are connected to each other through a T-connector. One end of the fourth air pipe 14 is connected to the vacuum pump 12. The other end of the fourth air pipe 14 is connected to the air tank 13.
[0024] The implementation principle of this embodiment is as follows: When it is necessary to inflate the rubber gas bag, the gas tank 13, the gas pipe and the vacuum pump 12 work together to fill the rubber gas bag with gas. The rubber gas bag expands rapidly, and the liquid level in the water seal tank 1 also rises accordingly. This achieves the effect of different water levels and different pressures during the gas release process. There are two rubber gas bags. When the gas release pressure does not change much, one rubber gas bag is used. When the gas release pressure changes greatly, both rubber gas bags are started at the same time to achieve the effect of quickly adjusting the release pressure.
[0025] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
