Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically a storage tank with a booster defrosting function. Background Technology

[0002] Currently, cryogenic storage tanks all adopt a double-walled cylindrical structure, including an inner container and an outer container. The inner container, as the most important component of the cryogenic storage tank, stores mostly flammable, explosive, and harmful liquefied gases and cryogenic liquids (such as liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, liquid carbon dioxide, liquid ethylene, etc.).

[0003] In existing technologies, storage tanks storing cryogenic liquid media require pressurization according to usage needs. Due to the low temperature of the cryogenic liquid, frost will form on the surface of the pressurizer, affecting its use. Defrosting requires manual hand tools, which is very inconvenient.

[0004] In view of this, there is an urgent need for a storage tank with a booster defrosting function. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A storage tank with a booster defrosting function includes: a tank body, on which a booster mechanism is provided, the booster mechanism including a booster body disposed on the tank body; The tank is equipped with a pressure relief pipe, one end of which extends to the top of the inner cavity of the tank, and the outlet of the pressure relief pipe faces the booster body. A first automatic pressure relief valve is provided on the pressure relief pipe. The pressure relief pipe is provided with a diversion pipe at its end, and a plurality of nozzles are provided on the diversion pipe, with the plurality of nozzles distributed along the axial direction of the diversion pipe.

[0007] The pressure relief pipe is a three-way pipe, which includes an inlet pipe, a first outlet pipe and a second outlet pipe. The first outlet pipe and the second outlet pipe are both connected to the inlet pipe. The inlet pipe extends into the inner cavity of the tank. The first outlet pipe is equipped with a second automatic pressure relief valve. The diversion pipe is located at the suspended end of the second outlet pipe. The first automatic pressure relief valve is located on the second outlet pipe.

[0008] The main body of the booster has fins arranged circumferentially in the pipeline, and the nozzle is oriented in the same direction as the extension of the fins.

[0009] A pressure gauge is installed on the tank.

[0010] The tank is equipped with a level gauge.

[0011] The booster mechanism also includes an input pipe, one end of which extends to the bottom of the inner cavity of the tank, and the other end is connected to the input port of the booster body.

[0012] An input valve is installed on the input pipe.

[0013] The booster mechanism also includes an output pipe, one end of which extends to the top of the inner cavity of the tank, and the other end is connected to the output port of the booster body.

[0014] An output valve is installed on the output pipe.

[0015] A pipeline safety valve is installed on the pipeline of the main body of the booster.

[0016] The above-described structure of this utility model can achieve the following beneficial effects: During use, the pressurizer mechanism pressurizes the tank, causing frost to form on the surface of the pressurizer's pipes. When the pressure inside the tank is high, the first automatic pressure relief valve opens, and the high-pressure gas inside the tank is sprayed out through the pressure relief pipe towards the pressurizer body, blowing away the frost on the surface of the pressurizer body and completing the defrosting work without the need for manual defrosting with hand tools. Furthermore, by setting up a diversion pipe to divert the high-pressure gas from the pressure relief pipe, the spraying area is increased, improving the defrosting effect.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0021] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0022] refer to Figure 1 and Figure 2 A storage tank with a booster defrosting function is shown, comprising: a tank body 1, a booster mechanism being provided on the tank body 1, the booster mechanism including a booster body 2 disposed on the tank body 1; A pressure relief pipe 3 is provided on the tank body 1. One end of the pressure relief pipe 3 extends to the top of the inner cavity of the tank body 1, and the outlet of the pressure relief pipe 3 faces the booster body 2. A first automatic pressure relief valve 4 is provided on the pressure relief pipe 3. The pressure relief pipe 3 is provided with a diversion pipe 13 at its end, and a number of nozzles 14 are provided on the diversion pipe 13, which are distributed along the axial direction of the diversion pipe 13.

[0023] Based on the above structure, during use, the pressurizer mechanism pressurizes the tank 1, causing frost to form on the surface of the pipes of the pressurizer body 2 (when the pressure inside the tank is low and pressurization is needed, the pressurizer mechanism operates; because the liquid flowing inside the pressurizer mechanism is cryogenic, a thin layer of frost will form initially, and with prolonged operation, a thicker layer of frost will form). When the pressure inside the tank 1 is high, the first automatic pressure relief valve 3 opens, and the high-pressure gas inside the tank 1 is ejected through the pressure relief pipe 3 into the pressurizer body 2, blowing away the frost on the surface of the pressurizer body 2 (after the tank is pressurized). When a certain pressure is reached, the first automatic pressure relief valve 4 will automatically work, using the overpressured gas to blow away the frost on the booster body 2; the longer the pressurization time of the storage tank 1, the more frost will form on the booster body 2, and the higher the pressure of the storage tank 1 will be. At this time, the first automatic pressure relief valve 4 will work more frequently, so that the frost on the booster body 2 can be thoroughly blown away, completing the defrosting work without the need for manual defrosting with hand tools; and by setting the diversion pipe 13 to divert the high-pressure gas from the pressure relief pipe 3, the blowing area is increased, and the defrosting effect is improved.

[0024] like Figure 1 and Figure 2As shown, the pressure relief pipe 3 is a three-way pipe, which includes an inlet pipe, a first outlet pipe, and a second outlet pipe. Both the first and second outlet pipes are connected to the inlet pipe. The inlet pipe extends into the inner cavity of the tank 1. The first outlet pipe is equipped with a second automatic pressure relief valve 5. The diversion pipe 13 is located at the suspended end of the second outlet pipe. The first automatic pressure relief valve 4 is located on the second outlet pipe. Thus, by setting the pressure relief pipe 3 as a three-way pipe and installing the second automatic pressure relief valve 5 on the first outlet pipe, when the pressure inside the tank 1 is too high, it can be automatically relieved through the first outlet pipe or the second outlet pipe. When the pressure inside the tank 1 is too high, the first automatic pressure relief valve 4 and the second automatic pressure relief valve 5 can also be opened simultaneously to relieve pressure.

[0025] Further optimization involves finning the pipeline of the turbocharger body 2 to facilitate heat exchange. The nozzle 14 is oriented in the same direction as the extension of the fins. In this way, the high-pressure gas ejected blows away the frost on the fins and pipeline along the extension direction of the fins.

[0026] like Figure 1 As shown, a pressure gauge 6 and a level gauge 7 are installed on the tank 1 to monitor the pressure and level inside the tank 1.

[0027] like Figure 1 As shown, specifically, the booster mechanism also includes an input pipe 8 and an output pipe 9. One end of the input pipe 8 extends to the bottom of the inner cavity of the tank 1, and the other end is connected to the input port of the booster body 2. An input valve 10 is provided on the input pipe 8. One end of the output pipe 9 extends to the top of the inner cavity of the tank 1, and the other end is connected to the output port of the booster body 2. An output valve 11 is provided on the output pipe 9. Thus, the opening and closing of the input pipe 8 and the output pipe 9 are controlled by the input valve 10 and the output valve 11, respectively.

[0028] A further optimization is that a pipeline safety valve 12 is installed on the pipeline of the booster body 2. Multiple pipeline safety valves 12 can be installed. After the booster body 2 is pressurized, a low-temperature liquid medium will remain inside. When the low-temperature liquid medium absorbs heat and vaporizes, its volume increases, which may cause safety hazards. Therefore, the pipeline safety valve 12 is used to release pressure in real time.

[0029] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
