Description

Technical Field

[0001] This utility model relates to the field of waste tire pyrolysis technology, specifically to a gas storage liquid seal tank. Background Technology

[0002] The amount of waste tires generated in my country is increasing by 8% to 10% annually, but the recycling rate is only about 50%. Many waste tires are discarded, polluting the environment and causing a huge waste of resources. After recycling, waste tires are often refined into fuel oil for reuse. Waste tire refining equipment can decompose various waste rubber, tires, and plastic products into fuel oil through high-temperature biomass processing.

[0003] Gas storage liquid-sealed tanks are required in the tire pyrolysis process. These tanks utilize the sealing properties of liquids to prevent leakage or backflow of gas or liquid media due to pressure differences. This technology employs basic concepts of fluid mechanics, using a suitable sealing fluid (such as water, grease, or oil) to create a specific liquid level difference within the sealing device. This balances pressure and prevents leakage. Traditional gas-liquid-sealed tanks typically have their pressure regulated by an explosion-proof flame arrestor breather valve on the tank top. However, the liquid-gas interface fluctuates significantly due to gas flow, leading to substantial waste of the liquid sealing medium. Therefore, improvements are necessary. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0024] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below. Example

[0025] A gas storage liquid-sealed tank includes a tank body 1. An air inlet 2 and a water inlet 3 are connected to the side wall of the tank body 1. A cap 4 is detachably installed on the upper end of the tank body 1, and an air outlet 5 is connected to the cap 4. A drain outlet 6 is provided at the lower end of the tank body 1. This storage liquid-sealed tank is installed in the middle of the process connecting the furnace chamber of a heating furnace and an oil storage tank. Through the liquid sealing effect, it can prevent backfire. Preferably, a pressure safety valve is installed at the air outlet 5. The upper end of the air outlet 5 is connected to the external heating furnace chamber through a gas pipe. The set pressure is generally 2000 Pa. The pressure safety valve automatically opens when the pressure inside the tank body 1 rises and exceeds a predetermined value, thereby reducing the internal pressure of the tank body 1 by discharging the gas medium to the outside. To improve the effect of preventing backfire, the tank body 1 is provided with an atmospheric pressure manhole 15, and a liquid sealing medium container 7 is installed at the bottom of the tank body 1. This liquid sealing tank is suitable for the process and scenario of waste tire oil refining. The liquid sealing medium is water. A buffer component is installed inside the tank body 1 to buffer the gas pressure inside the tank body 1. The buffer component is located above the liquid sealing medium container 7. By setting the buffer component, it has the flexibility to automatically balance the liquid sealing medium and gas pressure, buffer and reduce the fluctuation between the liquid sealing medium and gas interface, and reduce the liquid discharge loss caused by interface fluctuation. This solves the problem of serious waste of liquid sealing medium resources caused by the large fluctuation of the liquid sealing and gas interface due to the influence of gas flow in traditional gas liquid sealing devices.

[0026] In this embodiment, the buffer assembly includes an inflatable airbag 81, on which an air inlet pipe 82 is connected. The end of the air inlet pipe 82 penetrates the side wall of the tank 1 and is placed outside the tank 1. The air inlet pipe 82 is equipped with a flow control valve 83 and a pressure detection assembly. Inert gas can be injected into the inflatable airbag 81 for buffering according to the pressure parameters of the controlled gas. The airbag structure has the advantages of good buffering effect, low cost and convenient operation.

[0027] In this embodiment, the pressure detection component includes a branch air pipe 84 connected to the air inlet pipe 82. A pressure control valve 85 is installed on the branch air pipe 84, and a pressure gauge 86 is installed on the branch air pipe 84. The pressure gauge 86 can be used to observe whether the pressure inside the inflatable airbag 81 has reached the preset pressure, thereby determining whether to inflate.

[0028] In this embodiment, an observation mirror 9 is provided on the outside of the tank 1, through which staff can observe the situation inside the tank 1. Example

[0029] The difference between this embodiment and Embodiment 1 is that two vertical grooves 10 are also vertically formed on the outer side of the tank body 1. The vertical grooves 10 are rectangular in shape and are located on both sides of the observation mirror 9. A slider 11 is slidably connected in each vertical groove 10. A connecting plate 12 is fixedly connected to the opposite side of the slider 11. A baffle 13 is fixedly connected between the connecting plates 12. Liquid-sealed tanks are often used in workshops, but when transported or used in outdoor environments, the water and gas inside the liquid-sealed tank may be affected by various factors, such as the heat radiation of sunlight and direct light, which may directly affect the water. If the observation mirror 9 directly shines into the tank body 1, the gas space and water temperature in the tank body 1 will rise. This temperature rise may increase the internal gas pressure, thereby affecting its quality and safety, and may even pose a risk of explosion. Therefore, by setting the baffle 13, the observation mirror 9 can be shielded to prevent the heat radiation of sunlight or direct light from shining into the tank body 1 through the observation mirror 9, thereby improving the usage scenarios and applicability of the tank body 1.

[0030] In this embodiment, both the viewing mirror 9 and the baffle 13 are circular in shape, and the diameter of the baffle 13 is larger than the diameter of the viewing mirror 9, thereby improving the integrity of the baffle 13's obstruction.

[0031] A handle 14 is fixedly connected to the baffle 13. When the staff needs to observe the situation inside the tank 1 through the observation window 9, they can use their hands to hold the handle 14 to lift the baffle 13 upwards. The operation is simple and convenient.

[0032] The working principle and application scenarios of this utility model are as follows: This liquid-sealed tank is suitable for the process and scenario of waste tire oil pyrolysis, that is, the liquid medium to be sealed is fuel oil, which is obtained by the high-temperature biomass decomposition process of waste rubber, tires, and plastic products. A buffer component is installed inside the tank body 1 to buffer the gas pressure inside the tank body 1. The buffer component is located above the liquid-sealed medium container 7. By setting the buffer component, it has the flexibility to automatically balance the pressure of the liquid-sealed medium and the gas, buffering and reducing the fluctuation between the liquid-sealed medium and the gas interface, reducing the liquid discharge loss caused by the interface fluctuation, thereby solving the problem of liquid seal and gas interface in traditional gas liquid seal devices. The interface fluctuates greatly due to gas flow, resulting in a serious waste of liquid sealing medium resources. When using a buffer assembly, the buffer assembly includes an inflatable airbag 81. An air inlet pipe 82 is connected to the inflatable airbag 81. The end of the air inlet pipe 82 penetrates the side wall of the tank 1 and is placed outside the tank 1. The air inlet pipe 82 is equipped with a flow control valve 83 and a pressure detection component. According to the pressure parameters of the controlled gas, inert gas can be injected into the inflatable airbag 81 for buffering. The airbag structure has the advantages of good buffering effect, low cost and convenient operation. At the same time, the pressure detection component observes whether the pressure inside the inflatable airbag 81 reaches the preset pressure, thereby determining whether to inflate.

[0033] Liquid-sealed tanks are often used indoors, but during transportation or in outdoor environments, the water and gas inside may be affected by various factors, such as solar heat radiation and direct sunlight, which can directly impact the water. Direct sunlight entering the tank 1 through the viewing mirror 9 can raise the temperature of the gas and water inside the tank 1. This temperature increase may increase internal gas pressure, affecting its quality and safety, and even posing a risk of explosion. Therefore, two vertical grooves 10 are vertically formed on the outer side of the tank 1. These grooves are rectangular and located on either side of the viewing mirror 9. A slider 11 is slidably connected within each groove 10, and a connecting plate 12 is fixedly connected to the opposite side of each slider 11. A baffle 13 is fixedly connected between the connecting plates 12. By setting the baffle 13, the viewing mirror 9 is shielded, preventing solar heat radiation or direct sunlight from entering the tank 1 through the viewing mirror 9, thus improving the usability and scope of the tank 1.

[0034] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
