Description

Technical Field

[0001] The utility model relates to the technical field of gas engineering, in particular to a classified storage type standard gas distribution device. Background Art

[0002] As we all know, gas is one of the indispensable energy sources in people's lives. It is not only the main power raw material of factories, but also an important energy source for urban development. Common gases include natural gas, liquefied petroleum gas, artificial gas and biomass gas. These different gases have different functions and occupy different working areas. If they are reasonably allocated, there will be different effects. The gas distribution cabinet can configure the standard gas in proportion through its internal gas control valves, flow regulators and other components.

[0003] However, in the prior art, all configured standard gases are stored in a gas storage tank. This will result in that each time a different gas is configured, its gas distribution will be affected by the gas distributed last time, resulting in confusion in the standard gas components and affecting the final test results. For example, the last time the standard gas was liquefied gas, and the next time the standard gas is natural gas. Since their components and proportions are different, the residual gas of the liquefied gas standard gas in a gas storage tank will affect the subsequently distributed natural gas standard gas, and replacement is required. It takes about 6 to 7 replacements to meet the requirements, and this process produces huge losses. Therefore, a classified storage type standard gas distribution device is proposed to address the above problems. Utility Model Content

[0004] In order to solve the shortcomings of the prior art, the utility model proposes a classified storage type standard gas distribution device, which can independently manage each gas source tank while distributing gas to reduce waste due to replacement, improve the accuracy of the distributed standard gas, and increase resource utilization.

The outer surfaces of the multiple standard gas storage tanks are provided with standard gas classification labels.

[0006] As a further description of the above technical solution:

[0007] The pressure-stabilizing premixing assembly includes a second pressure-stabilizing tank and a premixing tank. The second pressure-stabilizing tank is connected to a manual valve of a gas distribution cabinet and an air inlet of the premixing tank.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] Reference Figure 1 , the utility model provides an embodiment: a classified storage type standard gas distribution device, including a gas distribution cabinet 6, the gas distribution cabinet 6 is connected to the total gas source 7 through multiple first pressure-stabilizing tanks 8, the total gas source 7 is various types of gas sources needed to configure standard gas, such as natural gas, that is, methane, propane, and nitrogen. The gas source quantity balance is automatically controlled by the purchased gas distribution cabinet 6. This device is an improvement on the configuration cabinet 6. The device also includes multiple standard gas storage tanks 3, preferably four, which are used to collect the successfully configured standard gases respectively. The gas outlet end of the gas distribution cabinet 6 is connected to multiple gas outlet channels, and manual valves 9 are installed on the surfaces of the gas outlet channels. Multiple standard gas storage tanks 3 are respectively connected to the corresponding manual valves 9. A pressure-stabilizing premixing component is also connected between the standard gas storage tank 3 and the manual valve 9 for stabilizing the pressure and avoiding gas stratification during gas distribution. The outer surfaces of the multiple standard gas storage tanks 3 are provided with standard gas classification labels 10, which can facilitate the classification of the standard gas types to be distributed.

[0024] The pressure stabilizing premixing component includes a second pressure stabilizing tank 1 and a premixing tank 2. The second pressure stabilizing tank 1 is connected to the manual valve 9 of the gas distribution cabinet 6 and the air inlet end of the premixing tank 2. The air outlet end of the premixing tank 2 is connected to the standard gas storage tank 3, which plays the role of pressure stabilization and premixing to avoid stratification. The air inlet end of the premixing tank 2 is provided with the top of the tank body, and the air outlet end is provided on the side wall of the tank body, which can better prevent stratification when discharging gas.

[0025] The gas distribution cabinet 6 is also connected to a spare tank 11, which is connected to the gas distribution cabinet 6 through a valve. The spare tank 11 is a reserved tank for discharging residual gas in the gas storage tank and replacing the gas storage tank. It is not used during normal gas distribution and is in a closed state.

[0026] The outer surfaces of the plurality of standard gas storage tanks 3 are provided with standard gas sampling points 4 and sampling valves 5. The standard gas sampling points 4 are connected to the gas inspection pipe for sampling and inspecting whether the configured standard gas meets the standard requirements.

[0027] The first pressure stabilizing tank 8 and the second pressure stabilizing tank 1 are both made of stainless steel material formed in one step, which can reduce the occurrence of gas leakage. They are 50 cm high, 30 cm wide, and sealed cylindrical containers. The premixing tank 2 is a cylindrical container group with a diameter of 30 cm and a height of 110 cm. The standard gas storage tank 3 is a cylindrical container with a diameter of 50 cm and a height of 180 cm.

[0028] When in use, first turn on the power of the total gas source 7 and the gas distribution cabinet 6, and set the required standard gas ratio. For example, if natural gas needs to be configured, the natural gas components are 85% methane, 13% propane, and 2% nitrogen after analysis by a gas chromatograph. When distributing the gas, we need to turn on the three gases of methane, propane, and nitrogen, and set the air intake volume on the gas distribution cabinet 6. After the gas distribution starts, the equipment automatically runs through computer control to configure the required standard gas. After the configuration is completed, the standard gas is stored separately in an independent standard gas storage tank 3, and the standard gas category is marked to prevent confusion in the use of the standard gas storage tank 3. When preparing other gases, they can be placed in different standard gas storage tanks 3 to avoid the need for replacement.

[0029] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
